An X.509 CRL (certificate revocation list) is a tool to help determine if a certificate is still valid. The exact definition of those can be found in the X.509 document from ITU-T, or in RFC3280 from PKIX. In OpenSSL, the type X509 is used to express such a certificate, and the type X509_CRL is used to express a CRL.</p> <p>A related structure is a certificate request, defined in PKCS#10 from RSA Security, Inc, also reflected in RFC2896. In OpenSSL, the type X509_REQ is used to express such a certificate request.</p> <p>To handle some complex parts of a certificate, there are the types X509_NAME (to express a certificate name), X509_ATTRIBUTE (to express a certificate attribute), X509_EXTENSION (to express a certificate extension) and a few more.</p> <p>Finally, there's the supertype X509_INFO, which can contain a CRL, a certificate and a corresponding private key.</p> <p><b>X509_</b><i>XXX</i>, <b>d2i_X509_</b><i>XXX</i>, and <b>i2d_X509_</b><i>XXX</i> functions handle X.509 certificates, with some exceptions, shown below.</p> <p><b>X509_CRL_</b><i>XXX</i>, <b>d2i_X509_CRL_</b><i>XXX</i>, and <b>i2d_X509_CRL_</b><i>XXX</i> functions handle X.509 CRLs.</p> <p><b>X509_REQ_</b><i>XXX</i>, <b>d2i_X509_REQ_</b><i>XXX</i>, and <b>i2d_X509_REQ_</b><i>XXX</i> functions handle PKCS#10 certificate requests.</p> <p><b>X509_NAME_</b><i>XXX</i> functions handle certificate names.</p> <p><b>X509_ATTRIBUTE_</b><i>XXX</i> functions handle certificate attributes.</p> <p><b>X509_EXTENSION_</b><i>XXX</i> functions handle certificate extensions.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/X509_NAME_ENTRY_get_object.html">X509_NAME_ENTRY_get_object(3)</a>, <a href="../man3/X509_NAME_add_entry_by_txt.html">X509_NAME_add_entry_by_txt(3)</a>, <a href="../man3/X509_NAME_add_entry_by_NID.html">X509_NAME_add_entry_by_NID(3)</a>, <a href="../man3/X509_NAME_print_ex.html">X509_NAME_print_ex(3)</a>, <a href="../man3/X509_NAME_new.html">X509_NAME_new(3)</a>, <a href="../man3/d2i_X509.html">d2i_X509(3)</a>, <a href="../man3/d2i_X509_ALGOR.html">d2i_X509_ALGOR(3)</a>, <a href="../man3/d2i_X509_CRL.html">d2i_X509_CRL(3)</a>, <a href="../man3/d2i_X509_NAME.html">d2i_X509_NAME(3)</a>, <a href="../man3/d2i_X509_REQ.html">d2i_X509_REQ(3)</a>, <a href="../man3/d2i_X509_SIG.html">d2i_X509_SIG(3)</a>, <a href="../man3/X509v3.html">X509v3(3)</a>, <a href="../man7/crypto.html">crypto(7)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2003-2021 The OpenSSL Project Authors.

This manual page attempts to give an overview over how this problem is currently addressed in different parts of the OpenSSL library.</p> <h2 id="The-general-case">The general case</h2> <p>The OpenSSL library doesn't treat pass phrases in any special way as a general rule, and trusts the application or user to choose a suitable character set and stick to that throughout the lifetime of affected objects. This means that for an object that was encrypted using a pass phrase encoded in ISO-8859-1, that object needs to be decrypted using a pass phrase encoded in ISO-8859-1. Using the wrong encoding is expected to cause a decryption failure.</p> <h2 id="PKCS-12">PKCS#12</h2> <p>PKCS#12 is a bit different regarding pass phrase encoding. The standard stipulates that the pass phrase shall be encoded as an ASN.1 BMPString, which consists of the code points of the basic multilingual plane, encoded in big endian (UCS-2 BE).</p> <p>OpenSSL tries to adapt to this requirements in one of the following manners:</p> <ol> <li><p>Treats the received pass phrase as UTF-8 encoded and tries to re-encode it to UTF-16 (which is the same as UCS-2 for characters U+0000 to U+D7FF and U+E000 to U+FFFF, but becomes an expansion for any other character), or failing that, proceeds with step 2.</p> </li> <li><p>Assumes that the pass phrase is encoded in ASCII or ISO-8859-1 and opportunistically prepends each byte with a zero byte to obtain the UCS-2 encoding of the characters, which it stores as a BMPString.</p> <p>Note that since there is no check of your locale, this may produce UCS-2 / UTF-16 characters that do not correspond to the original pass phrase characters for other character sets, such as any ISO-8859-X encoding other than ISO-8859-1 (or for Windows, CP 1252 with exception for the extra "graphical" characters in the 0x80-0x9F range).</p> </li> </ol> <p>OpenSSL versions older than 1.1.0 do variant 2 only, and that is the reason why OpenSSL still does this, to be able to read files produced with older versions.</p> <p>It should be noted that this approach isn't entirely fault free.</p> <p>A pass phrase encoded in ISO-8859-2 could very well have a sequence such as 0xC3 0xAF (which is the two characters "LATIN CAPITAL LETTER A WITH BREVE" and "LATIN CAPITAL LETTER Z WITH DOT ABOVE" in ISO-8859-2 encoding), but would be misinterpreted as the perfectly valid UTF-8 encoded code point U+00EF (LATIN SMALL LETTER I WITH DIAERESIS) <i>if the pass phrase doesn't contain anything that would be invalid UTF-8</i>. A pass phrase that contains this kind of byte sequence will give a different outcome in OpenSSL 1.1.0 and newer than in OpenSSL older than 1.1.0.</p> <pre><code> 0x00 0xC3 0x00 0xAF # OpenSSL older than 1.1.0 0x00 0xEF # OpenSSL 1.1.0 and newer</code></pre> <p>On the same accord, anything encoded in UTF-8 that was given to OpenSSL older than 1.1.0 was misinterpreted as ISO-8859-1 sequences.</p> <h2 id="OSSL_STORE">OSSL_STORE</h2> <p><a href="../man7/ossl_store.html">ossl_store(7)</a> acts as a general interface to access all kinds of objects, potentially protected with a pass phrase, a PIN or something else. This API stipulates that pass phrases should be UTF-8 encoded, and that any other pass phrase encoding may give undefined results. This API relies on the application to ensure UTF-8 encoding, and doesn't check that this is the case, so what it gets, it will also pass to the underlying loader.</p> <h1 id="RECOMMENDATIONS">RECOMMENDATIONS</h1> <p>This section assumes that you know what pass phrase was used for encryption, but that it may have been encoded in a different character encoding than the one used by your current input method. For example, the pass phrase may have been used at a time when your default encoding was ISO-8859-1 (i.e. "naïve" resulting in the byte sequence 0x6E 0x61 0xEF 0x76 0x65), and you're now in an environment where your default encoding is UTF-8 (i.e. "naïve" resulting in the byte sequence 0x6E 0x61 0xC3 0xAF 0x76 0x65). Whenever it's mentioned that you should use a certain character encoding, it should be understood that you either change the input method to use the mentioned encoding when you type in your pass phrase, or use some suitable tool to convert your pass phrase from your default encoding to the target encoding.</p> <p>Also note that the sub-sections below discuss human readable pass phrases. This is particularly relevant for PKCS#12 objects, where human readable pass phrases are assumed. For other objects, it's as legitimate to use any byte sequence (such as a sequence of bytes from `/dev/urandom` that's been saved away), which makes any character encoding discussion irrelevant; in such cases, simply use the same byte sequence as it is.</p> <h2 id="Creating-new-objects">Creating new objects</h2> <p>For creating new pass phrase protected objects, make sure the pass phrase is encoded using UTF-8. This is default on most modern Unixes, but may involve an effort on other platforms. Specifically for Windows, setting the environment variable <code>OPENSSL_WIN32_UTF8</code> will have anything entered on [Windows] console prompt converted to UTF-8 (command line and separately prompted pass phrases alike).</p> <h2 id="Opening-existing-objects">Opening existing objects</h2> <p>For opening pass phrase protected objects where you know what character encoding was used for the encryption pass phrase, make sure to use the same encoding again.</p> <p>For opening pass phrase protected objects where the character encoding that was used is unknown, or where the producing application is unknown, try one of the following:</p> <ol> <li><p>Try the pass phrase that you have as it is in the character encoding of your environment. It's possible that its byte sequence is exactly right.</p> </li> <li><p>Convert the pass phrase to UTF-8 and try with the result. Specifically with PKCS#12, this should open up any object that was created according to the specification.</p> </li> <li><p>Do a naïve (i.e. purely mathematical) ISO-8859-1 to UTF-8 conversion and try with the result. This differs from the previous attempt because ISO-8859-1 maps directly to U+0000 to U+00FF, which other non-UTF-8 character sets do not.</p> <p>This also takes care of the case when a UTF-8 encoded string was used with OpenSSL older than 1.1.0. (for example, <code>ï</code>, which is 0xC3 0xAF when encoded in UTF-8, would become 0xC3 0x83 0xC2 0xAF when re-encoded in the naïve manner. The conversion to BMPString would then yield 0x00 0xC3 0x00 0xA4 0x00 0x00, the erroneous/non-compliant encoding used by OpenSSL older than 1.1.0)</p> </li> </ol> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/evp.html">evp(7)</a>, <a href="../man7/ossl_store.html">ossl_store(7)</a>, <a href="../man3/EVP_BytesToKey.html">EVP_BytesToKey(3)</a>, <a href="../man3/EVP_DecryptInit.html">EVP_DecryptInit(3)</a>, <a href="../man3/PEM_do_header.html">PEM_do_header(3)</a>, <a href="../man3/PKCS12_parse.html">PKCS12_parse(3)</a>, <a href="../man3/PKCS12_newpass.html">PKCS12_newpass(3)</a>, <a href="../man3/d2i_PKCS8PrivateKey_bio.html">d2i_PKCS8PrivateKey_bio(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2018-2020 The OpenSSL Project Authors.

It is memory-hard in the sense that it deliberately requires a significant amount of RAM for efficient computation. The intention of this is to render brute forcing of passwords on systems that lack large amounts of main memory (such as GPUs or ASICs) computationally infeasible.</p> <p>scrypt provides three work factors that can be customized: N, r and p. N, which has to be a positive power of two, is the general work factor and scales CPU time in an approximately linear fashion. r is the block size of the internally used hash function and p is the parallelization factor. Both r and p need to be greater than zero. The amount of RAM that scrypt requires for its computation is roughly (128 * N * r * p) bytes.</p> <p>In the original paper of Colin Percival ("Stronger Key Derivation via Sequential Memory-Hard Functions", 2009), the suggested values that give a computation time of less than 5 seconds on a 2.5 GHz Intel Core 2 Duo are N = 2^20 = 1048576, r = 8, p = 1. Consequently, the required amount of memory for this computation is roughly 1 GiB. On a more recent CPU (Intel i7-5930K at 3.5 GHz), this computation takes about 3 seconds. When N, r or p are not specified, they default to 1048576, 8, and 1, respectively.

Some may refuse non-PEM content for the sake of determinism (for example, there are keys out in the wild that are represented as an ASN.1 OCTET STRING. In raw form, it's not easily possible to distinguish those from any other data coming as an ASN.1 OCTET STRING, so such keys would naturally be accepted as PEM files only).</p> <h1 id="NOTES">NOTES</h1> <p>When needed, the 'file' scheme loader will require a pass phrase by using the <code>UI_METHOD</code> that was passed via OSSL_STORE_open().

Software-based generators must be seeded with external randomness before they can be used as a cryptographically-secure pseudo-random number generator (CSPRNG). The availability of common hardware with special instructions and modern operating systems, which may use items such as interrupt jitter and network packet timings, can be reasonable sources of seeding material.</p> <p>OpenSSL comes with a default implementation of the RAND API which is based on the deterministic random bit generator (DRBG) model as described in [NIST SP 800-90A Rev. 1]. The default random generator will initialize automatically on first use and will be fully functional without having to be initialized ('seeded') explicitly. It seeds and reseeds itself automatically using trusted random sources provided by the operating system.</p> <p>As a normal application developer, you do not have to worry about any details, just use <a href="../man3/RAND_bytes.html">RAND_bytes(3)</a> to obtain random data. Having said that, there is one important rule to obey: Always check the error return value of <a href="../man3/RAND_bytes.html">RAND_bytes(3)</a> and do not take randomness for granted. Although (re-)seeding is automatic, it can fail because no trusted random source is available or the trusted source(s) temporarily fail to provide sufficient random seed material. In this case the CSPRNG enters an error state and ceases to provide output, until it is able to recover from the error by reseeding itself. For more details on reseeding and error recovery, see <a href="../man7/RAND_DRBG.html">RAND_DRBG(7)</a>.</p> <p>For values that should remain secret, you can use <a href="../man3/RAND_priv_bytes.html">RAND_priv_bytes(3)</a> instead. This method does not provide 'better' randomness, it uses the same type of CSPRNG. The intention behind using a dedicated CSPRNG exclusively for private values is that none of its output should be visible to an attacker (e.g., used as salt value), in order to reveal as little information as possible about its internal state, and that a compromise of the "public" CSPRNG instance will not affect the secrecy of these private values.</p> <p>In the rare case where the default implementation does not satisfy your special requirements, there are two options:</p> <ul> <li><p>Replace the default RAND method by your own RAND method using <a href="../man3/RAND_set_rand_method.html">RAND_set_rand_method(3)</a>.</p> </li> <li><p>Modify the default settings of the OpenSSL RAND method by modifying the security parameters of the underlying DRBG, which is described in detail in <a href="../man7/RAND_DRBG.html">RAND_DRBG(7)</a>.</p> </li> </ul> <p>Changing the default random generator or its default parameters should be necessary only in exceptional cases and is not recommended, unless you have a profound knowledge of cryptographic principles and understand the implications of your changes.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/RAND_add.html">RAND_add(3)</a>, <a href="../man3/RAND_bytes.html">RAND_bytes(3)</a>, <a href="../man3/RAND_priv_bytes.html">RAND_priv_bytes(3)</a>, <a href="../man3/RAND_get_rand_method.html">RAND_get_rand_method(3)</a>, <a href="../man3/RAND_set_rand_method.html">RAND_set_rand_method(3)</a>, <a href="../man3/RAND_OpenSSL.html">RAND_OpenSSL(3)</a>, <a href="../man7/RAND_DRBG.html">RAND_DRBG(7)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2018-2019 The OpenSSL Project Authors.

A DRBG is a certain type of cryptographically-secure pseudo-random number generator (CSPRNG), which is described in [NIST SP 800-90A Rev. 1].</p> <p>While the RAND API is the 'frontend' which is intended to be used by application developers for obtaining random bytes, the RAND_DRBG API serves as the 'backend', connecting the former with the operating systems's entropy sources and providing access to the DRBG's configuration parameters.</p> <h2 id="Disclaimer">Disclaimer</h2> <p>Unless you have very specific requirements for your random generator, it is in general not necessary to utilize the RAND_DRBG API directly. The usual way to obtain random bytes is to use <a href="../man3/RAND_bytes.html">RAND_bytes(3)</a> or <a href="../man3/RAND_priv_bytes.html">RAND_priv_bytes(3)</a>, see also <a href="../man7/RAND.html">RAND(7)</a>.</p> <h2 id="Typical-Use-Cases">Typical Use Cases</h2> <p>Typical examples for such special use cases are the following:</p> <ul> <li><p>You want to use your own private DRBG instances. Multiple DRBG instances which are accessed only by a single thread provide additional security (because their internal states are independent) and better scalability in multithreaded applications (because they don't need to be locked).</p> </li> <li><p>You need to integrate a previously unsupported entropy source.</p> </li> <li><p>You need to change the default settings of the standard OpenSSL RAND implementation to meet specific requirements.</p> </li> </ul> <h1 id="CHAINING">CHAINING</h1> <p>A DRBG instance can be used as the entropy source of another DRBG instance, provided it has itself access to a valid entropy source. The DRBG instance which acts as entropy source is called the <i>parent</i> DRBG, the other instance the <i>child</i> DRBG.</p> <p>This is called chaining. A chained DRBG instance is created by passing a pointer to the parent DRBG as argument to the RAND_DRBG_new() call. It is possible to create chains of more than two DRBG in a row.</p> <h1 id="THE-THREE-SHARED-DRBG-INSTANCES">THE THREE SHARED DRBG INSTANCES</h1> <p>Currently, there are three shared DRBG instances, the <master>, <public>, and <private> DRBG. While the <master> DRBG is a single global instance, the <public> and <private> DRBG are created per thread and accessed through thread-local storage.</p> <p>By default, the functions <a href="../man3/RAND_bytes.html">RAND_bytes(3)</a> and <a href="../man3/RAND_priv_bytes.html">RAND_priv_bytes(3)</a> use the thread-local <public> and <private> DRBG instance, respectively.</p> <h2 id="The-master-DRBG-instance">The <master> DRBG instance</h2> <p>The <master> DRBG is not used directly by the application, only for reseeding the two other two DRBG instances. It reseeds itself by obtaining randomness either from os entropy sources or by consuming randomness which was added previously by <a href="../man3/RAND_add.html">RAND_add(3)</a>.</p> <h2 id="The-public-DRBG-instance">The <public> DRBG instance</h2> <p>This instance is used per default by <a href="../man3/RAND_bytes.html">RAND_bytes(3)</a>.</p> <h2 id="The-private-DRBG-instance">The <private> DRBG instance</h2> <p>This instance is used per default by <a href="../man3/RAND_priv_bytes.html">RAND_priv_bytes(3)</a></p> <h1 id="LOCKING">LOCKING</h1> <p>The <master> DRBG is intended to be accessed concurrently for reseeding by its child DRBG instances. The necessary locking is done internally. It is <i>not</i> thread-safe to access the <master> DRBG directly via the RAND_DRBG interface. The <public> and <private> DRBG are thread-local, i.e. there is an instance of each per thread. So they can safely be accessed without locking via the RAND_DRBG interface.</p> <p>Pointers to these DRBG instances can be obtained using RAND_DRBG_get0_master(), RAND_DRBG_get0_public(), and RAND_DRBG_get0_private(), respectively. Note that it is not allowed to store a pointer to one of the thread-local DRBG instances in a variable or other memory location where it will be accessed and used by multiple threads.</p> <p>All other DRBG instances created by an application don't support locking, because they are intended to be used by a single thread. Instead of accessing a single DRBG instance concurrently from different threads, it is recommended to instantiate a separate DRBG instance per thread. Using the <master> DRBG as entropy source for multiple DRBG instances on different threads is thread-safe, because the DRBG instance will lock the <master> DRBG automatically for obtaining random input.</p> <h1 id="THE-OVERALL-PICTURE">THE OVERALL PICTURE</h1> <p>The following picture gives an overview over how the DRBG instances work together and are being used.</p> <pre><code> +--------------------+ | os entropy sources | +--------------------+ | v +-----------------------------+ RAND_add() ==> <master> <-| shared DRBG (with locking) | / \ +-----------------------------+ / \ +---------------------------+ <public> <private> <- | per-thread DRBG instances | | | +---------------------------+ v v RAND_bytes() RAND_priv_bytes() | ^ | | +------------------+ +------------------------------------+ | general purpose | | used for secrets like session keys | | random generator | | and private keys for certificates | +------------------+ +------------------------------------+</code></pre> <p>The usual way to obtain random bytes is to call RAND_bytes(...) or RAND_priv_bytes(...). These calls are roughly equivalent to calling RAND_DRBG_bytes(<public>, ...) and RAND_DRBG_bytes(<private>, ...), respectively. The method <a href="../man3/RAND_DRBG_bytes.html">RAND_DRBG_bytes(3)</a> is a convenience method wrapping the <a href="../man3/RAND_DRBG_generate.html">RAND_DRBG_generate(3)</a> function, which serves the actual request for random data.</p> <h1 id="RESEEDING">RESEEDING</h1> <p>A DRBG instance seeds itself automatically, pulling random input from its entropy source. The entropy source can be either a trusted operating system entropy source, or another DRBG with access to such a source.</p> <p>Automatic reseeding occurs after a predefined number of generate requests. The selection of the trusted entropy sources is configured at build time using the --with-rand-seed option. The following sections explain the reseeding process in more detail.</p> <h2 id="Automatic-Reseeding">Automatic Reseeding</h2> <p>Before satisfying a generate request (<a href="../man3/RAND_DRBG_generate.html">RAND_DRBG_generate(3)</a>), the DRBG reseeds itself automatically, if one of the following conditions holds:</p> <p>- the DRBG was not instantiated (=seeded) yet or has been uninstantiated.</p> <p>- the number of generate requests since the last reseeding exceeds a certain threshold, the so called <i>reseed_interval</i>. This behaviour can be disabled by setting the <i>reseed_interval</i> to 0.</p> <p>- the time elapsed since the last reseeding exceeds a certain time interval, the so called <i>reseed_time_interval</i>. This can be disabled by setting the <i>reseed_time_interval</i> to 0.</p> <p>- the DRBG is in an error state.</p> <p><b>Note</b>: An error state is entered if the entropy source fails while the DRBG is seeding or reseeding. The last case ensures that the DRBG automatically recovers from the error as soon as the entropy source is available again.</p> <h2 id="Manual-Reseeding">Manual Reseeding</h2> <p>In addition to automatic reseeding, the caller can request an immediate reseeding of the DRBG with fresh entropy by setting the <i>prediction resistance</i> parameter to 1 when calling <a href="../man3/RAND_DRBG_generate.html">RAND_DRBG_generate(3)</a>.</p> <p>The document [NIST SP 800-90C] describes prediction resistance requests in detail and imposes strict conditions on the entropy sources that are approved for providing prediction resistance. Since the default DRBG implementation does not have access to such an approved entropy source, a request for prediction resistance will currently always fail. In other words, prediction resistance is currently not supported yet by the DRBG.</p> <p>For the three shared DRBGs (and only for these) there is another way to reseed them manually: If <a href="../man3/RAND_add.html">RAND_add(3)</a> is called with a positive <i>randomness</i> argument (or <a href="../man3/RAND_seed.html">RAND_seed(3)</a>), then this will immediately reseed the <master> DRBG. The <public> and <private> DRBG will detect this on their next generate call and reseed, pulling randomness from <master>.</p> <p>The last feature has been added to support the common practice used with previous OpenSSL versions to call RAND_add() before calling RAND_bytes().</p> <h2 id="Entropy-Input-vs.-Additional-Data">Entropy Input vs. Additional Data</h2> <p>The DRBG distinguishes two different types of random input: <i>entropy</i>, which comes from a trusted source, and <i>additional input</i>', which can optionally be added by the user and is considered untrusted. It is possible to add <i>additional input</i> not only during reseeding, but also for every generate request. This is in fact done automatically by <a href="../man3/RAND_DRBG_bytes.html">RAND_DRBG_bytes(3)</a>.</p> <h2 id="Configuring-the-Random-Seed-Source">Configuring the Random Seed Source</h2> <p>In most cases OpenSSL will automatically choose a suitable seed source for automatically seeding and reseeding its <master> DRBG. In some cases however, it will be necessary to explicitly specify a seed source during configuration, using the --with-rand-seed option. For more information, see the INSTALL instructions. There are also operating systems where no seed source is available and automatic reseeding is disabled by default.</p> <p>The following two sections describe the reseeding process of the master DRBG, depending on whether automatic reseeding is available or not.</p> <h2 id="Reseeding-the-master-DRBG-with-automatic-seeding-enabled">Reseeding the master DRBG with automatic seeding enabled</h2> <p>Calling RAND_poll() or RAND_add() is not necessary, because the DRBG pulls the necessary entropy from its source automatically. However, both calls are permitted, and do reseed the RNG.</p> <p>RAND_add() can be used to add both kinds of random input, depending on the value of the <b>randomness</b> argument:</p> <dl> <dt id="randomness-0">randomness == 0:</dt> <dd> <p>The random bytes are mixed as additional input into the current state of the DRBG. Mixing in additional input is not considered a full reseeding, hence the reseed counter is not reset.</p> </dd> <dt id="randomness-01">randomness > 0:</dt> <dd> <p>The random bytes are used as entropy input for a full reseeding (resp. reinstantiation) if the DRBG is instantiated (resp. uninstantiated or in an error state). The number of random bits required for reseeding is determined by the security strength of the DRBG. Currently it defaults to 256 bits (32 bytes). It is possible to provide less randomness than required. In this case the missing randomness will be obtained by pulling random input from the trusted entropy sources.</p> </dd> </dl> <h2 id="Reseeding-the-master-DRBG-with-automatic-seeding-disabled">Reseeding the master DRBG with automatic seeding disabled</h2> <p>Calling RAND_poll() will always fail.</p> <p>RAND_add() needs to be called for initial seeding and periodic reseeding. At least 48 bytes (384 bits) of randomness have to be provided, otherwise the (re-)seeding of the DRBG will fail. This corresponds to one and a half times the security strength of the DRBG. The extra half is used for the nonce during instantiation.</p> <p>More precisely, the number of bytes needed for seeding depend on the <i>security strength</i> of the DRBG, which is set to 256 by default.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/RAND_DRBG_bytes.html">RAND_DRBG_bytes(3)</a>, <a href="../man3/RAND_DRBG_generate.html">RAND_DRBG_generate(3)</a>, <a href="../man3/RAND_DRBG_reseed.html">RAND_DRBG_reseed(3)</a>, <a href="../man3/RAND_DRBG_get0_master.html">RAND_DRBG_get0_master(3)</a>, <a href="../man3/RAND_DRBG_get0_public.html">RAND_DRBG_get0_public(3)</a>, <a href="../man3/RAND_DRBG_get0_private.html">RAND_DRBG_get0_private(3)</a>, <a href="../man3/RAND_DRBG_set_reseed_interval.html">RAND_DRBG_set_reseed_interval(3)</a>, <a href="../man3/RAND_DRBG_set_reseed_time_interval.html">RAND_DRBG_set_reseed_time_interval(3)</a>, <a href="../man3/RAND_DRBG_set_reseed_defaults.html">RAND_DRBG_set_reseed_defaults(3)</a>, <a href="../man7/RAND.html">RAND(7)</a>,</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2017-2018 The OpenSSL Project Authors.

If an application uses a BIO for its I/O it can transparently handle SSL connections, unencrypted network connections and file I/O.</p> <p>There are two type of BIO, a source/sink BIO and a filter BIO.</p> <p>As its name implies a source/sink BIO is a source and/or sink of data, examples include a socket BIO and a file BIO.</p> <p>A filter BIO takes data from one BIO and passes it through to another, or the application. The data may be left unmodified (for example a message digest BIO) or translated (for example an encryption BIO). The effect of a filter BIO may change according to the I/O operation it is performing: for example an encryption BIO will encrypt data if it is being written to and decrypt data if it is being read from.</p> <p>BIOs can be joined together to form a chain (a single BIO is a chain with one component). A chain normally consist of one source/sink BIO and one or more filter BIOs. Data read from or written to the first BIO then traverses the chain to the end (normally a source/sink BIO).</p> <p>Some BIOs (such as memory BIOs) can be used immediately after calling BIO_new(). Others (such as file BIOs) need some additional initialization, and frequently a utility function exists to create and initialize such BIOs.</p> <p>If BIO_free() is called on a BIO chain it will only free one BIO resulting in a memory leak.</p> <p>Calling BIO_free_all() on a single BIO has the same effect as calling BIO_free() on it other than the discarded return value.</p> <p>Normally the <b>type</b> argument is supplied by a function which returns a pointer to a BIO_METHOD. There is a naming convention for such functions: a source/sink BIO is normally called BIO_s_*() and a filter BIO BIO_f_*();</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Create a memory BIO:</p> <pre><code> BIO *mem = BIO_new(BIO_s_mem());</code></pre> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/BIO_ctrl.html">BIO_ctrl(3)</a>, <a href="../man3/BIO_f_base64.html">BIO_f_base64(3)</a>, <a href="../man3/BIO_f_buffer.html">BIO_f_buffer(3)</a>, <a href="../man3/BIO_f_cipher.html">BIO_f_cipher(3)</a>, <a href="../man3/BIO_f_md.html">BIO_f_md(3)</a>, <a href="../man3/BIO_f_null.html">BIO_f_null(3)</a>, <a href="../man3/BIO_f_ssl.html">BIO_f_ssl(3)</a>, <a href="../man3/BIO_find_type.html">BIO_find_type(3)</a>, <a href="../man3/BIO_new.html">BIO_new(3)</a>, <a href="../man3/BIO_new_bio_pair.html">BIO_new_bio_pair(3)</a>, <a href="../man3/BIO_push.html">BIO_push(3)</a>, <a href="../man3/BIO_read_ex.html">BIO_read_ex(3)</a>, <a href="../man3/BIO_s_accept.html">BIO_s_accept(3)</a>, <a href="../man3/BIO_s_bio.html">BIO_s_bio(3)</a>, <a href="../man3/BIO_s_connect.html">BIO_s_connect(3)</a>, <a href="../man3/BIO_s_fd.html">BIO_s_fd(3)</a>, <a href="../man3/BIO_s_file.html">BIO_s_file(3)</a>, <a href="../man3/BIO_s_mem.html">BIO_s_mem(3)</a>, <a href="../man3/BIO_s_null.html">BIO_s_null(3)</a>, <a href="../man3/BIO_s_socket.html">BIO_s_socket(3)</a>, <a href="../man3/BIO_set_callback.html">BIO_set_callback(3)</a>, <a href="../man3/BIO_should_retry.html">BIO_should_retry(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2019 The OpenSSL Project Authors.

Base 64 encoding converts binary data into a printable form that uses the characters A-Z, a-z, 0-9, "+" and "/" to represent the data. For every 3 bytes of binary data provided 4 bytes of base 64 encoded data will be produced plus some occasional newlines (see below). If the input data length is not a multiple of 3 then the output data will be padded at the end using the "=" character.</p> <p>EVP_ENCODE_CTX_new() allocates, initializes and returns a context to be used for the encode/decode functions.</p> <p>EVP_ENCODE_CTX_free() cleans up an encode/decode context <b>ctx</b> and frees up the space allocated to it.</p> <p>Encoding of binary data is performed in blocks of 48 input bytes (or less for the final block). For each 48 byte input block encoded 64 bytes of base 64 data is output plus an additional newline character (i.e. 65 bytes in total). The final block (which may be less than 48 bytes) will output 4 bytes for every 3 bytes of input. If the data length is not divisible by 3 then a full 4 bytes is still output for the final 1 or 2 bytes of input. Similarly a newline character will also be output.</p> <p>EVP_EncodeInit() initialises <b>ctx</b> for the start of a new encoding operation.</p> <p>EVP_EncodeUpdate() encode <b>inl</b> bytes of data found in the buffer pointed to by <b>in</b>. The output is stored in the buffer <b>out</b> and the number of bytes output is stored in <b>*outl</b>. It is the caller's responsibility to ensure that the buffer at <b>out</b> is sufficiently large to accommodate the output data. Only full blocks of data (48 bytes) will be immediately processed and output by this function. Any remainder is held in the <b>ctx</b> object and will be processed by a subsequent call to EVP_EncodeUpdate() or EVP_EncodeFinal(). To calculate the required size of the output buffer add together the value of <b>inl</b> with the amount of unprocessed data held in <b>ctx</b> and divide the result by 48 (ignore any remainder). This gives the number of blocks of data that will be processed. Ensure the output buffer contains 65 bytes of storage for each block, plus an additional byte for a NUL terminator. EVP_EncodeUpdate() may be called repeatedly to process large amounts of input data. In the event of an error EVP_EncodeUpdate() will set <b>*outl</b> to 0 and return 0. On success 1 will be returned.</p> <p>EVP_EncodeFinal() must be called at the end of an encoding operation. It will process any partial block of data remaining in the <b>ctx</b> object. The output data will be stored in <b>out</b> and the length of the data written will be stored in <b>*outl</b>. It is the caller's responsibility to ensure that <b>out</b> is sufficiently large to accommodate the output data which will never be more than 65 bytes plus an additional NUL terminator (i.e. 66 bytes in total).</p> <p>EVP_ENCODE_CTX_copy() can be used to copy a context <b>sctx</b> to a context <b>dctx</b>. <b>dctx</b> must be initialized before calling this function.</p> <p>EVP_ENCODE_CTX_num() will return the number of as yet unprocessed bytes still to be encoded or decoded that are pending in the <b>ctx</b> object.</p> <p>EVP_EncodeBlock() encodes a full block of input data in <b>f</b> and of length <b>n</b> and stores it in <b>t</b>. For every 3 bytes of input provided 4 bytes of output data will be produced. If <b>n</b> is not divisible by 3 then the block is encoded as a final block of data and the output is padded such that it is always divisible by 4. Additionally a NUL terminator character will be added. For example if 16 bytes of input data is provided then 24 bytes of encoded data is created plus 1 byte for a NUL terminator (i.e. 25 bytes in total). The length of the data generated <i>without</i> the NUL terminator is returned from the function.</p> <p>EVP_DecodeInit() initialises <b>ctx</b> for the start of a new decoding operation.</p> <p>EVP_DecodeUpdate() decodes <b>inl</b> characters of data found in the buffer pointed to by <b>in</b>. The output is stored in the buffer <b>out</b> and the number of bytes output is stored in <b>*outl</b>. It is the caller's responsibility to ensure that the buffer at <b>out</b> is sufficiently large to accommodate the output data. This function will attempt to decode as much data as possible in 4 byte chunks. Any whitespace, newline or carriage return characters are ignored. Any partial chunk of unprocessed data (1, 2 or 3 bytes) that remains at the end will be held in the <b>ctx</b> object and processed by a subsequent call to EVP_DecodeUpdate(). If any illegal base 64 characters are encountered or if the base 64 padding character "=" is encountered in the middle of the data then the function returns -1 to indicate an error. A return value of 0 or 1 indicates successful processing of the data. A return value of 0 additionally indicates that the last input data characters processed included the base 64 padding character "=" and therefore no more non-padding character data is expected to be processed. For every 4 valid base 64 bytes processed (ignoring whitespace, carriage returns and line feeds), 3 bytes of binary output data will be produced (or less at the end of the data where the padding character "=" has been used).</p> <p>EVP_DecodeFinal() must be called at the end of a decoding operation. If there is any unprocessed data still in <b>ctx</b> then the input data must not have been a multiple of 4 and therefore an error has occurred. The function will return -1 in this case. Otherwise the function returns 1 on success.</p> <p>EVP_DecodeBlock() will decode the block of <b>n</b> characters of base 64 data contained in <b>f</b> and store the result in <b>t</b>. Any leading whitespace will be trimmed as will any trailing whitespace, newlines, carriage returns or EOF characters. After such trimming the length of the data in <b>f</b> must be divisible by 4. For every 4 input bytes exactly 3 output bytes will be produced. The output will be padded with 0 bits if necessary to ensure that the output is always 3 bytes for every 4 input bytes. This function will return the length of the data decoded or -1 on error.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>EVP_ENCODE_CTX_new() returns a pointer to the newly allocated EVP_ENCODE_CTX object or NULL on error.</p> <p>EVP_ENCODE_CTX_num() returns the number of bytes pending encoding or decoding in <b>ctx</b>.</p> <p>EVP_EncodeUpdate() returns 0 on error or 1 on success.</p> <p>EVP_EncodeBlock() returns the number of bytes encoded excluding the NUL terminator.</p> <p>EVP_DecodeUpdate() returns -1 on error and 0 or 1 on success.

The first form is those defined over the prime field Fp. The elements of Fp are the integers 0 to p-1, where p is a prime number. This gives us a revised elliptic curve equation as follows:</p> <p>y^2 mod p = x^3 +ax + b mod p</p> <p>The second form is those defined over a binary field F2^m where the elements of the field are integers of length at most m bits. For this form the elliptic curve equation is modified to:</p> <p>y^2 + xy = x^3 + ax^2 + b (where b != 0)</p> <p>Operations in a binary field are performed relative to an <b>irreducible polynomial</b>. All such curves with OpenSSL use a trinomial or a pentanomial for this parameter.</p> <p>A new curve can be constructed by calling EC_GROUP_new(), using the implementation provided by <b>meth</b> (see <a href="../man3/EC_GFp_simple_method.html">EC_GFp_simple_method(3)</a>). It is then necessary to call EC_GROUP_set_curve() to set the curve parameters. EC_GROUP_new_from_ecparameters() will create a group from the specified <b>params</b> and EC_GROUP_new_from_ecpkparameters() will create a group from the specific PK <b>params</b>.</p> <p>EC_GROUP_set_curve() sets the curve parameters <b>p</b>, <b>a</b> and <b>b</b>. For a curve over Fp <b>p</b> is the prime for the field. For a curve over F2^m <b>p</b> represents the irreducible polynomial - each bit represents a term in the polynomial. Therefore, there will either be three or five bits set dependent on whether the polynomial is a trinomial or a pentanomial. In either case, <b>a</b> and <b>b</b> represents the coefficients a and b from the relevant equation introduced above.</p> <p>EC_group_get_curve() obtains the previously set curve parameters.</p> <p>EC_GROUP_set_curve_GFp() and EC_GROUP_set_curve_GF2m() are synonyms for EC_GROUP_set_curve(). They are defined for backwards compatibility only and should not be used.</p> <p>EC_GROUP_get_curve_GFp() and EC_GROUP_get_curve_GF2m() are synonyms for EC_GROUP_get_curve(). They are defined for backwards compatibility only and should not be used.</p> <p>The functions EC_GROUP_new_curve_GFp() and EC_GROUP_new_curve_GF2m() are shortcuts for calling EC_GROUP_new() and then the EC_GROUP_set_curve() function. An appropriate default implementation method will be used.</p> <p>Whilst the library can be used to create any curve using the functions described above, there are also a number of predefined curves that are available. In order to obtain a list of all of the predefined curves, call the function EC_get_builtin_curves(). The parameter <b>r</b> should be an array of EC_builtin_curve structures of size <b>nitems</b>. The function will populate the <b>r</b> array with information about the builtin curves. If <b>nitems</b> is less than the total number of curves available, then the first <b>nitems</b> curves will be returned. Otherwise the total number of curves will be provided. The return value is the total number of curves available (whether that number has been populated in <b>r</b> or not). Passing a NULL <b>r</b>, or setting <b>nitems</b> to 0 will do nothing other than return the total number of curves available. The EC_builtin_curve structure is defined as follows:</p> <pre><code> typedef struct { int nid; const char *comment; } EC_builtin_curve;</code></pre> <p>Each EC_builtin_curve item has a unique integer id (<b>nid</b>), and a human readable comment string describing the curve.</p> <p>In order to construct a builtin curve use the function EC_GROUP_new_by_curve_name() and provide the <b>nid</b> of the curve to be constructed.</p> <p>EC_GROUP_free() frees the memory associated with the EC_GROUP. If <b>group</b> is NULL nothing is done.</p> <p>EC_GROUP_clear_free() destroys any sensitive data held within the EC_GROUP and then frees its memory.

Through user-written methods (see <a href="../man3/UI_create_method.html">UI_create_method(3)</a>), prompting can be done in any way imaginable, be it plain text prompting, through dialog boxes or from a cell phone.</p> <p>All the functions work through a context of the type UI. This context contains all the information needed to prompt correctly as well as a reference to a UI_METHOD, which is an ordered vector of functions that carry out the actual prompting.</p> <p>The first thing to do is to create a UI with UI_new() or UI_new_method(), then add information to it with the UI_add or UI_dup functions. Also, user-defined random data can be passed down to the underlying method through calls to UI_add_user_data() or UI_dup_user_data(). The default UI method doesn't care about these data, but other methods might. Finally, use UI_process() to actually perform the prompting and UI_get0_result() and UI_get_result_length() to find the result to the prompt and its length.</p> <p>A UI can contain more than one prompt, which are performed in the given sequence. Each prompt gets an index number which is returned by the UI_add and UI_dup functions, and has to be used to get the corresponding result with UI_get0_result() and UI_get_result_length().</p> <p>UI_process() can be called more than once on the same UI, thereby allowing a UI to have a long lifetime, but can just as well have a short lifetime.</p> <p>The functions are as follows:</p> <p>UI_new() creates a new UI using the default UI method. When done with this UI, it should be freed using UI_free().</p> <p>UI_new_method() creates a new UI using the given UI method. When done with this UI, it should be freed using UI_free().</p> <p>UI_OpenSSL() returns the built-in UI method (note: not necessarily the default one, since the default can be changed. See further on). This method is the most machine/OS dependent part of OpenSSL and normally generates the most problems when porting.</p> <p>UI_null() returns a UI method that does nothing. Its use is to avoid getting internal defaults for passed UI_METHOD pointers.</p> <p>UI_free() removes a UI from memory, along with all other pieces of memory that's connected to it, like duplicated input strings, results and others. If <b>ui</b> is NULL nothing is done.</p> <p>UI_add_input_string() and UI_add_verify_string() add a prompt to the UI, as well as flags and a result buffer and the desired minimum and maximum sizes of the result, not counting the final NUL character. The given information is used to prompt for information, for example a password, and to verify a password (i.e. having the user enter it twice and check that the same string was entered twice). UI_add_verify_string() takes and extra argument that should be a pointer to the result buffer of the input string that it's supposed to verify, or verification will fail.</p> <p>UI_add_input_boolean() adds a prompt to the UI that's supposed to be answered in a boolean way, with a single character for yes and a different character for no. A set of characters that can be used to cancel the prompt is given as well. The prompt itself is divided in two, one part being the descriptive text (given through the <i>prompt</i> argument) and one describing the possible answers (given through the <i>action_desc</i> argument).</p> <p>UI_add_info_string() and UI_add_error_string() add strings that are shown at the same time as the prompt for extra information or to show an error string. The difference between the two is only conceptual. With the builtin method, there's no technical difference between them. Other methods may make a difference between them, however.</p> <p>The flags currently supported are <b>UI_INPUT_FLAG_ECHO</b>, which is relevant for UI_add_input_string() and will have the users response be echoed (when prompting for a password, this flag should obviously not be used, and <b>UI_INPUT_FLAG_DEFAULT_PWD</b>, which means that a default password of some sort will be used (completely depending on the application and the UI method).</p> <p>UI_dup_input_string(), UI_dup_verify_string(), UI_dup_input_boolean(), UI_dup_info_string() and UI_dup_error_string() are basically the same as their UI_add counterparts, except that they make their own copies of all strings.</p> <p>UI_construct_prompt() is a helper function that can be used to create a prompt from two pieces of information: an description and a name. The default constructor (if there is none provided by the method used) creates a string "Enter <i>description</i> for <i>name</i>:". With the description "pass phrase" and the filename "foo.key", that becomes "Enter pass phrase for foo.key:". Other methods may create whatever string and may include encodings that will be processed by the other method functions.</p> <p>UI_add_user_data() adds a user data pointer for the method to use at any time. The builtin UI method doesn't care about this info. Note that several calls to this function doesn't add data, it replaces the previous blob with the one given as argument.</p> <p>UI_dup_user_data() duplicates the user data and works as an alternative to UI_add_user_data() when the user data needs to be preserved for a longer duration, perhaps even the lifetime of the application. The UI object takes ownership of this duplicate and will free it whenever it gets replaced or the UI is destroyed. UI_dup_user_data() returns 0 on success, or -1 on memory allocation failure or if the method doesn't have a duplicator function.</p> <p>UI_get0_user_data() retrieves the data that has last been given to the UI with UI_add_user_data() or UI_dup_user_data.</p> <p>UI_get0_result() returns a pointer to the result buffer associated with the information indexed by <i>i</i>.</p> <p>UI_get_result_length() returns the length of the result buffer associated with the information indexed by <i>i</i>.</p> <p>UI_process() goes through the information given so far, does all the printing and prompting and returns the final status, which is -2 on out-of-band events (Interrupt, Cancel, ...), -1 on error and 0 on success.</p> <p>UI_ctrl() adds extra control for the application author. For now, it understands two commands: <b>UI_CTRL_PRINT_ERRORS</b>, which makes UI_process() print the OpenSSL error stack as part of processing the UI, and <b>UI_CTRL_IS_REDOABLE</b>, which returns a flag saying if the used UI can be used again or not.</p> <p>UI_set_default_method() changes the default UI method to the one given. This function is not thread-safe and should not be called at the same time as other OpenSSL functions.</p> <p>UI_get_default_method() returns a pointer to the current default UI method.</p> <p>UI_get_method() returns the UI method associated with a given UI.</p> <p>UI_set_method() changes the UI method associated with a given UI.</p> <h1 id="NOTES">NOTES</h1> <p>The resulting strings that the built in method UI_OpenSSL() generate are assumed to be encoded according to the current locale or (for Windows) code page. For applications having different demands, these strings need to be converted appropriately by the caller. For Windows, if the OPENSSL_WIN32_UTF8 environment variable is set, the built-in method UI_OpenSSL() will produce UTF-8 encoded strings instead.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>UI_new() and UI_new_method() return a valid <b>UI</b> structure or NULL if an error occurred.</p> <p>UI_add_input_string(), UI_dup_input_string(), UI_add_verify_string(), UI_dup_verify_string(), UI_add_input_boolean(), UI_dup_input_boolean(), UI_add_info_string(), UI_dup_info_string(), UI_add_error_string() and UI_dup_error_string() return a positive number on success or a value which is less than or equal to 0 otherwise.</p> <p>UI_construct_prompt() returns a string or NULL if an error occurred.</p> <p>UI_dup_user_data() returns 0 on success or -1 on error.</p> <p>UI_get0_result() returns a string or NULL on error.</p> <p>UI_get_result_length() returns a positive integer or 0 on success; otherwise it returns -1 on error.</p> <p>UI_process() returns 0 on success or a negative value on error.</p> <p>UI_ctrl() returns a mask on success or -1 on error.</p> <p>UI_get_default_method(), UI_get_method(), UI_OpenSSL(), UI_null() and UI_set_method() return either a valid <b>UI_METHOD</b> structure or NULL respectively.</p> <h1 id="HISTORY">HISTORY</h1> <p>The UI_dup_user_data() function was added in OpenSSL 1.1.1.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2001-2020 The OpenSSL Project Authors.

It provides a set of functions used by OpenSSL for the implementation of the various RSA capabilities. See the <a href="/../man1/rsa.html">rsa</a> page for more information.</p> <p>RSA_meth_new() creates a new <b>RSA_METHOD</b> structure. It should be given a unique <b>name</b> and a set of <b>flags</b>. The <b>name</b> should be a NULL terminated string, which will be duplicated and stored in the <b>RSA_METHOD</b> object. It is the callers responsibility to free the original string. The flags will be used during the construction of a new <b>RSA</b> object based on this <b>RSA_METHOD</b>. Any new <b>RSA</b> object will have those flags set by default.</p> <p>RSA_meth_dup() creates a duplicate copy of the <b>RSA_METHOD</b> object passed as a parameter. This might be useful for creating a new <b>RSA_METHOD</b> based on an existing one, but with some differences.</p> <p>RSA_meth_free() destroys an <b>RSA_METHOD</b> structure and frees up any memory associated with it.</p> <p>RSA_meth_get0_name() will return a pointer to the name of this RSA_METHOD. This is a pointer to the internal name string and so should not be freed by the caller. RSA_meth_set1_name() sets the name of the RSA_METHOD to <b>name</b>. The string is duplicated and the copy is stored in the RSA_METHOD structure, so the caller remains responsible for freeing the memory associated with the name.</p> <p>RSA_meth_get_flags() returns the current value of the flags associated with this RSA_METHOD.

This function will be called in response to the application calling RSA_free(). A pointer to the RSA to be destroyed is passed as a parameter. The destroy function should be used for RSA implementation specific clean up. The memory for the RSA itself should not be freed by this function.

These CRLs will only be used if CRL verification is enabled in the associated <b>X509_VERIFY_PARAM</b> structure. This might be used where additional "useful" CRLs are supplied as part of a protocol, for example in a PKCS#7 structure.</p> <p>X509_STORE_CTX_get0_param() retrieves an internal pointer to the verification parameters associated with <b>ctx</b>.</p> <p>X509_STORE_CTX_get0_untrusted() retrieves an internal pointer to the stack of untrusted certificates associated with <b>ctx</b>.</p> <p>X509_STORE_CTX_set0_untrusted() sets the internal point to the stack of untrusted certificates associated with <b>ctx</b> to <b>sk</b>.</p> <p>X509_STORE_CTX_set0_param() sets the internal verification parameter pointer to <b>param</b>.

This uses the function X509_VERIFY_PARAM_lookup() to find an appropriate set of parameters from <b>name</b>.</p> <p>X509_STORE_CTX_get_num_untrusted() returns the number of untrusted certificates that were used in building the chain following a call to X509_verify_cert().</p> <p>X509_STORE_CTX_set_verify() provides the capability for overriding the default verify function. This function is responsible for verifying chain signatures and expiration times.</p> <p>A verify function is defined as an X509_STORE_CTX_verify type which has the following signature:</p> <pre><code> int (*verify)(X509_STORE_CTX *);</code></pre> <p>This function should receive the current X509_STORE_CTX as a parameter and return 1 on success or 0 on failure.</p> <p>X509 certificates may contain information about what purposes keys contained within them can be used for. For example "TLS WWW Server Authentication" or "Email Protection". This "key usage" information is held internally to the certificate itself. In addition the trust store containing trusted certificates can declare what purposes we trust different certificates for. This "trust" information is not held within the certificate itself but is "meta" information held alongside it. This "meta" information is associated with the certificate after it is issued and could be determined by a system administrator. For example a certificate might declare that it is suitable for use for both "TLS WWW Server Authentication" and "TLS Client Authentication", but a system administrator might only trust it for the former. An X.509 certificate extension exists that can record extended key usage information to supplement the purpose information described above. This extended mechanism is arbitrarily extensible and not well suited for a generic library API; applications that need to validate extended key usage information in certifiates will need to define a custom "purpose" (see below) or supply a nondefault verification callback (<a href="../man3/X509_STORE_set_verify_cb_func.html">X509_STORE_set_verify_cb_func(3)</a>).</p> <p>X509_STORE_CTX_set_purpose() sets the purpose for the target certificate being verified in the <i>ctx</i>. Built-in available values for the <i>purpose</i> argument are <b>X509_PURPOSE_SSL_CLIENT</b>, <b>X509_PURPOSE_SSL_SERVER</b>, <b>X509_PURPOSE_NS_SSL_SERVER</b>, <b>X509_PURPOSE_SMIME_SIGN</b>, <b>X509_PURPOSE_SMIME_ENCRYPT</b>, <b>X509_PURPOSE_CRL_SIGN</b>, <b>X509_PURPOSE_ANY</b>, <b>X509_PURPOSE_OCSP_HELPER</b> and <b>X509_PURPOSE_TIMESTAMP_SIGN</b>. It is also possible to create a custom purpose value. Setting a purpose will ensure that the key usage declared within certificates in the chain being verified is consistent with that purpose as well as, potentially, other checks. Every purpose also has an associated default trust value which will also be set at the same time. During verification this trust setting will be verified to check it is consistent with the trust set by the system administrator for certificates in the chain.</p> <p>X509_STORE_CTX_set_trust() sets the trust value for the target certificate being verified in the <i>ctx</i>. Built-in available values for the <i>trust</i> argument are <b>X509_TRUST_COMPAT</b>, <b>X509_TRUST_SSL_CLIENT</b>, <b>X509_TRUST_SSL_SERVER</b>, <b>X509_TRUST_EMAIL</b>, <b>X509_TRUST_OBJECT_SIGN</b>, <b>X509_TRUST_OCSP_SIGN</b>, <b>X509_TRUST_OCSP_REQUEST</b> and <b>X509_TRUST_TSA</b>. It is also possible to create a custom trust value. Since X509_STORE_CTX_set_purpose() also sets the trust value it is normally sufficient to only call that function. If both are called then X509_STORE_CTX_set_trust() should be called after X509_STORE_CTX_set_purpose() since the trust setting of the last call will be used.</p> <p>It should not normally be necessary for end user applications to call X509_STORE_CTX_purpose_inherit() directly. Typically applications should call X509_STORE_CTX_set_purpose() or X509_STORE_CTX_set_trust() instead. Using this function it is possible to set the purpose and trust values for the <i>ctx</i> at the same time. Both <i>ctx</i> and its internal verification parameter pointer must not be NULL. The <i>def_purpose</i> and <i>purpose</i> arguments can have the same purpose values as described for X509_STORE_CTX_set_purpose() above. The <i>trust</i> argument can have the same trust values as described in X509_STORE_CTX_set_trust() above. Any of the <i>def_purpose</i>, <i>purpose</i> or <i>trust</i> values may also have the value 0 to indicate that the supplied parameter should be ignored. After calling this function the purpose to be used for verification is set from the <i>purpose</i> argument unless the purpose was already set in <i>ctx</i> before, and the trust is set from the <i>trust</i> argument unless the trust was already set in <i>ctx</i> before. If <i>trust</i> is 0 then the trust value will be set from the default trust value for <i>purpose</i>. If the default trust value for the purpose is <i>X509_TRUST_DEFAULT</i> and <i>trust</i> is 0 then the default trust value associated with the <i>def_purpose</i> value is used for the trust setting instead.</p> <h1 id="NOTES">NOTES</h1> <p>The certificates and CRLs in a store are used internally and should <b>not</b> be freed up until after the associated <b>X509_STORE_CTX</b> is freed.</p> <h1 id="BUGS">BUGS</h1> <p>The certificates and CRLs in a context are used internally and should <b>not</b> be freed up until after the associated <b>X509_STORE_CTX</b> is freed.

In this sense PEM format is simply base64 encoded data surrounded by header lines.</p> <p>For more details about the meaning of arguments see the <b>PEM FUNCTION ARGUMENTS</b> section.</p> <p>Each operation has four functions associated with it. For brevity the term "<b>TYPE</b> functions" will be used below to collectively refer to the PEM_read_bio_TYPE(), PEM_read_TYPE(), PEM_write_bio_TYPE(), and PEM_write_TYPE() functions.</p> <p>The <b>PrivateKey</b> functions read or write a private key in PEM format using an EVP_PKEY structure. The write routines use PKCS#8 private key format and are equivalent to PEM_write_bio_PKCS8PrivateKey().The read functions transparently handle traditional and PKCS#8 format encrypted and unencrypted keys.</p> <p>PEM_write_bio_PrivateKey_traditional() writes out a private key in the "traditional" format with a simple private key marker and should only be used for compatibility with legacy programs.</p> <p>PEM_write_bio_PKCS8PrivateKey() and PEM_write_PKCS8PrivateKey() write a private key in an EVP_PKEY structure in PKCS#8 EncryptedPrivateKeyInfo format using PKCS#5 v2.0 password based encryption algorithms. The <b>cipher</b> argument specifies the encryption algorithm to use: unlike some other PEM routines the encryption is applied at the PKCS#8 level and not in the PEM headers. If <b>cipher</b> is NULL then no encryption is used and a PKCS#8 PrivateKeyInfo structure is used instead.</p> <p>PEM_write_bio_PKCS8PrivateKey_nid() and PEM_write_PKCS8PrivateKey_nid() also write out a private key as a PKCS#8 EncryptedPrivateKeyInfo however it uses PKCS#5 v1.5 or PKCS#12 encryption algorithms instead. The algorithm to use is specified in the <b>nid</b> parameter and should be the NID of the corresponding OBJECT IDENTIFIER (see NOTES section).</p> <p>The <b>PUBKEY</b> functions process a public key using an EVP_PKEY structure. The public key is encoded as a SubjectPublicKeyInfo structure.</p> <p>The <b>RSAPrivateKey</b> functions process an RSA private key using an RSA structure. The write routines uses traditional format. The read routines handles the same formats as the <b>PrivateKey</b> functions but an error occurs if the private key is not RSA.</p> <p>The <b>RSAPublicKey</b> functions process an RSA public key using an RSA structure. The public key is encoded using a PKCS#1 RSAPublicKey structure.</p> <p>The <b>RSA_PUBKEY</b> functions also process an RSA public key using an RSA structure. However, the public key is encoded using a SubjectPublicKeyInfo structure and an error occurs if the public key is not RSA.</p> <p>The <b>DSAPrivateKey</b> functions process a DSA private key using a DSA structure. The write routines uses traditional format. The read routines handles the same formats as the <b>PrivateKey</b> functions but an error occurs if the private key is not DSA.</p> <p>The <b>DSA_PUBKEY</b> functions process a DSA public key using a DSA structure. The public key is encoded using a SubjectPublicKeyInfo structure and an error occurs if the public key is not DSA.</p> <p>The <b>Parameters</b> functions read or write key parameters in PEM format using an EVP_PKEY structure. The encoding depends on the type of key; for DSA key parameters, it will be a Dss-Parms structure as defined in RFC2459, and for DH key parameters, it will be a PKCS#3 DHparameter structure. <i>These functions only exist for the <b>BIO</b> type</i>.</p> <p>The <b>DSAparams</b> functions process DSA parameters using a DSA structure. The parameters are encoded using a Dss-Parms structure as defined in RFC2459.</p> <p>The <b>DHparams</b> functions process DH parameters using a DH structure. The parameters are encoded using a PKCS#3 DHparameter structure.</p> <p>The <b>X509</b> functions process an X509 certificate using an X509 structure. They will also process a trusted X509 certificate but any trust settings are discarded.</p> <p>The <b>X509_AUX</b> functions process a trusted X509 certificate using an X509 structure.</p> <p>The <b>X509_REQ</b> and <b>X509_REQ_NEW</b> functions process a PKCS#10 certificate request using an X509_REQ structure. The <b>X509_REQ</b> write functions use <b>CERTIFICATE REQUEST</b> in the header whereas the <b>X509_REQ_NEW</b> functions use <b>NEW CERTIFICATE REQUEST</b> (as required by some CAs). The <b>X509_REQ</b> read functions will handle either form so there are no <b>X509_REQ_NEW</b> read functions.</p> <p>The <b>X509_CRL</b> functions process an X509 CRL using an X509_CRL structure.</p> <p>The <b>PKCS7</b> functions process a PKCS#7 ContentInfo using a PKCS7 structure.</p> <h1 id="PEM-FUNCTION-ARGUMENTS">PEM FUNCTION ARGUMENTS</h1> <p>The PEM functions have many common arguments.</p> <p>The <b>bp</b> BIO parameter (if present) specifies the BIO to read from or write to.</p> <p>The <b>fp</b> FILE parameter (if present) specifies the FILE pointer to read from or write to.</p> <p>The PEM read functions all take an argument <b>TYPE **x</b> and return a <b>TYPE *</b> pointer. Where <b>TYPE</b> is whatever structure the function uses. If <b>x</b> is NULL then the parameter is ignored. If <b>x</b> is not NULL but <b>*x</b> is NULL then the structure returned will be written to <b>*x</b>. If neither <b>x</b> nor <b>*x</b> is NULL then an attempt is made to reuse the structure at <b>*x</b> (but see BUGS and EXAMPLES sections). Irrespective of the value of <b>x</b> a pointer to the structure is always returned (or NULL if an error occurred).</p> <p>The PEM functions which write private keys take an <b>enc</b> parameter which specifies the encryption algorithm to use, encryption is done at the PEM level. If this parameter is set to NULL then the private key is written in unencrypted form.</p> <p>The <b>cb</b> argument is the callback to use when querying for the pass phrase used for encrypted PEM structures (normally only private keys).</p> <p>For the PEM write routines if the <b>kstr</b> parameter is not NULL then <b>klen</b> bytes at <b>kstr</b> are used as the passphrase and <b>cb</b> is ignored.</p> <p>If the <b>cb</b> parameters is set to NULL and the <b>u</b> parameter is not NULL then the <b>u</b> parameter is interpreted as a null terminated string to use as the passphrase. If both <b>cb</b> and <b>u</b> are NULL then the default callback routine is used which will typically prompt for the passphrase on the current terminal with echoing turned off.</p> <p>The default passphrase callback is sometimes inappropriate (for example in a GUI application) so an alternative can be supplied. The callback routine has the following form:</p> <pre><code> int cb(char *buf, int size, int rwflag, void *u);</code></pre> <p><b>buf</b> is the buffer to write the passphrase to. <b>size</b> is the maximum length of the passphrase (i.e. the size of buf). <b>rwflag</b> is a flag which is set to 0 when reading and 1 when writing. A typical routine will ask the user to verify the passphrase (for example by prompting for it twice) if <b>rwflag</b> is 1. The <b>u</b> parameter has the same value as the <b>u</b> parameter passed to the PEM routine. It allows arbitrary data to be passed to the callback by the application (for example a window handle in a GUI application). The callback <b>must</b> return the number of characters in the passphrase or -1 if an error occurred.</p> <h1 id="NOTES">NOTES</h1> <p>The old <b>PrivateKey</b> write routines are retained for compatibility. New applications should write private keys using the PEM_write_bio_PKCS8PrivateKey() or PEM_write_PKCS8PrivateKey() routines because they are more secure (they use an iteration count of 2048 whereas the traditional routines use a count of 1) unless compatibility with older versions of OpenSSL is important.</p> <p>The <b>PrivateKey</b> read routines can be used in all applications because they handle all formats transparently.</p> <p>A frequent cause of problems is attempting to use the PEM routines like this:</p> <pre><code> X509 *x; PEM_read_bio_X509(bp, &x, 0, NULL);</code></pre> <p>this is a bug because an attempt will be made to reuse the data at <b>x</b> which is an uninitialised pointer.</p> <p>These functions make no assumption regarding the pass phrase received from the password callback. It will simply be treated as a byte sequence.</p> <h1 id="PEM-ENCRYPTION-FORMAT">PEM ENCRYPTION FORMAT</h1> <p>These old <b>PrivateKey</b> routines use a non standard technique for encryption.</p> <p>The private key (or other data) takes the following form:</p> <pre><code> -----BEGIN RSA PRIVATE KEY----- Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,3F17F5316E2BAC89 ...base64 encoded data... -----END RSA PRIVATE KEY-----</code></pre> <p>The line beginning with <i>Proc-Type</i> contains the version and the protection on the encapsulated data. The line beginning <i>DEK-Info</i> contains two comma separated values: the encryption algorithm name as used by EVP_get_cipherbyname() and an initialization vector used by the cipher encoded as a set of hexadecimal digits. After those two lines is the base64-encoded encrypted data.</p> <p>The encryption key is derived using EVP_BytesToKey(). The cipher's initialization vector is passed to EVP_BytesToKey() as the <b>salt</b> parameter. Internally, <b>PKCS5_SALT_LEN</b> bytes of the salt are used (regardless of the size of the initialization vector). The user's password is passed to EVP_BytesToKey() using the <b>data</b> and <b>datal</b> parameters. Finally, the library uses an iteration count of 1 for EVP_BytesToKey().</p> <p>The <b>key</b> derived by EVP_BytesToKey() along with the original initialization vector is then used to decrypt the encrypted data. The <b>iv</b> produced by EVP_BytesToKey() is not utilized or needed, and NULL should be passed to the function.</p> <p>The pseudo code to derive the key would look similar to:</p> <pre><code> EVP_CIPHER* cipher = EVP_des_ede3_cbc(); EVP_MD* md = EVP_md5(); unsigned int nkey = EVP_CIPHER_key_length(cipher); unsigned int niv = EVP_CIPHER_iv_length(cipher); unsigned char key[nkey]; unsigned char iv[niv]; memcpy(iv, HexToBin("3F17F5316E2BAC89"), niv); rc = EVP_BytesToKey(cipher, md, iv /*salt*/, pword, plen, 1, key, NULL /*iv*/); if (rc != nkey) /* Error */ /* On success, use key and iv to initialize the cipher */</code></pre> <h1 id="BUGS">BUGS</h1> <p>The PEM read routines in some versions of OpenSSL will not correctly reuse an existing structure. Therefore, the following:</p> <pre><code> PEM_read_bio_X509(bp, &x, 0, NULL);</code></pre> <p>where <b>x</b> already contains a valid certificate, may not work, whereas:</p> <pre><code> X509_free(x); x = PEM_read_bio_X509(bp, NULL, 0, NULL);</code></pre> <p>is guaranteed to work.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The read routines return either a pointer to the structure read or NULL if an error occurred.</p> <p>The write routines return 1 for success or 0 for failure.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Although the PEM routines take several arguments in almost all applications most of them are set to 0 or NULL.</p> <p>Read a certificate in PEM format from a BIO:</p> <pre><code> X509 *x; x = PEM_read_bio_X509(bp, NULL, 0, NULL); if (x == NULL) /* Error */</code></pre> <p>Alternative method:</p> <pre><code> X509 *x = NULL; if (!PEM_read_bio_X509(bp, &x, 0, NULL)) /* Error */</code></pre> <p>Write a certificate to a BIO:</p> <pre><code> if (!PEM_write_bio_X509(bp, x)) /* Error */</code></pre> <p>Write a private key (using traditional format) to a BIO using triple DES encryption, the pass phrase is prompted for:</p> <pre><code> if (!PEM_write_bio_PrivateKey(bp, key, EVP_des_ede3_cbc(), NULL, 0, 0, NULL)) /* Error */</code></pre> <p>Write a private key (using PKCS#8 format) to a BIO using triple DES encryption, using the pass phrase "hello":</p> <pre><code> if (!PEM_write_bio_PKCS8PrivateKey(bp, key, EVP_des_ede3_cbc(), NULL, 0, 0, "hello")) /* Error */</code></pre> <p>Read a private key from a BIO using a pass phrase callback:</p> <pre><code> key = PEM_read_bio_PrivateKey(bp, NULL, pass_cb, "My Private Key"); if (key == NULL) /* Error */</code></pre> <p>Skeleton pass phrase callback:</p> <pre><code> int pass_cb(char *buf, int size, int rwflag, void *u) { /* We'd probably do something else if 'rwflag' is 1 */ printf("Enter pass phrase for \"%s\"\n", (char *)u); /* get pass phrase, length 'len' into 'tmp' */ char *tmp = "hello"; if (tmp == NULL) /* An error occurred */ return -1; size_t len = strlen(tmp); if (len > size) len = size; memcpy(buf, tmp, len); return len; }</code></pre> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/EVP_EncryptInit.html">EVP_EncryptInit(3)</a>, <a href="../man3/EVP_BytesToKey.html">EVP_BytesToKey(3)</a>, <a href="../man7/passphrase-encoding.html">passphrase-encoding(7)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The old Netscape certificate sequences were no longer documented in OpenSSL 1.1.0; applications should use the PKCS7 standard instead as they will be formally deprecated in a future releases.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2001-2020 The OpenSSL Project Authors.

They constitute a promise by a Certificate Transparency (CT) log to publicly record a certificate. By cryptographically verifying that a log did indeed issue an SCT, some confidence can be gained that the certificate is publicly known.</p> <p>An internal representation of an SCT can be created in one of two ways. The first option is to create a blank SCT, using SCT_new(), and then populate it using:</p> <ul> <li><p>SCT_set_version() to set the SCT version.</p> <p>Only SCT_VERSION_V1 is currently supported.</p> </li> <li><p>SCT_set_log_entry_type() to set the type of certificate the SCT was issued for:</p> <p><b>CT_LOG_ENTRY_TYPE_X509</b> for a normal certificate. <b>CT_LOG_ENTRY_TYPE_PRECERT</b> for a pre-certificate.</p> </li> <li><p>SCT_set0_log_id() or SCT_set1_log_id() to set the LogID of the CT log that the SCT came from.</p> <p>The former takes ownership, whereas the latter makes a copy. See RFC 6962, Section 3.2 for the definition of LogID.</p> </li> <li><p>SCT_set_timestamp() to set the time the SCT was issued (epoch time in milliseconds).</p> </li> <li><p>SCT_set_signature_nid() to set the NID of the signature.</p> </li> <li><p>SCT_set0_signature() or SCT_set1_signature() to set the raw signature value.</p> <p>The former takes ownership, whereas the latter makes a copy.</p> </li> <li><p>SCT_set0_extensions() or <b>SCT_set1_extensions</b> to provide SCT extensions.</p> <p>The former takes ownership, whereas the latter makes a copy.</p> </li> </ul> <p>Alternatively, the SCT can be pre-populated from the following data using SCT_new_from_base64():</p> <ul> <li><p>The SCT version (only SCT_VERSION_V1 is currently supported).</p> </li> <li><p>The LogID (see RFC 6962, Section 3.2), base64 encoded.</p> </li> <li><p>The type of certificate the SCT was issued for: <b>CT_LOG_ENTRY_TYPE_X509</b> for a normal certificate. <b>CT_LOG_ENTRY_TYPE_PRECERT</b> for a pre-certificate.</p> </li> <li><p>The time that the SCT was issued (epoch time in milliseconds).</p> </li> <li><p>The SCT extensions, base64 encoded.</p> </li> <li><p>The SCT signature, base64 encoded.</p> </li> </ul> <p>SCT_set_source() can be used to record where the SCT was found (TLS extension, X.509 certificate extension or OCSP response). This is not required for verifying the SCT.</p> <h1 id="NOTES">NOTES</h1> <p>Some of the setters return int, instead of void. These will all return 1 on success, 0 on failure. They will not make changes on failure.</p> <p>All of the setters will reset the validation status of the SCT to SCT_VALIDATION_STATUS_NOT_SET (see <a href="../man3/SCT_validate.html">SCT_validate(3)</a>).</p> <p>SCT_set_source() will call SCT_set_log_entry_type() if the type of certificate the SCT was issued for can be inferred from where the SCT was found.

Individual connections associated with the context can then enable per-connection DANE support as appropriate. DANE authentication is implemented in the <a href="../man3/X509_verify_cert.html">X509_verify_cert(3)</a> function, and applications that override <a href="../man3/X509_verify_cert.html">X509_verify_cert(3)</a> via <a href="../man3/SSL_CTX_set_cert_verify_callback.html">SSL_CTX_set_cert_verify_callback(3)</a> are responsible to authenticate the peer chain in whatever manner they see fit.</p> <p>SSL_CTX_dane_mtype_set() may then be called zero or more times to adjust the supported digest algorithms. This must be done before any SSL handles are created for the context.</p> <p>The <b>mtype</b> argument specifies a DANE TLSA matching type and the <b>md</b> argument specifies the associated digest algorithm handle. The <b>ord</b> argument specifies a strength ordinal. Algorithms with a larger strength ordinal are considered more secure. Strength ordinals are used to implement RFC7671 digest algorithm agility. Specifying a <b>NULL</b> digest algorithm for a matching type disables support for that matching type. Matching type Full(0) cannot be modified or disabled.</p> <p>By default, matching type <code>SHA2-256(1)</code> (see RFC7218 for definitions of the DANE TLSA parameter acronyms) is mapped to <code>EVP_sha256()</code> with a strength ordinal of <code>1</code> and matching type <code>SHA2-512(2)</code> is mapped to <code>EVP_sha512()</code> with a strength ordinal of <code>2</code>.</p> <p>SSL_dane_enable() must be called before the SSL handshake is initiated with <a href="../man3/SSL_connect.html">SSL_connect(3)</a> if (and only if) you want to enable DANE for that connection. (The connection must be associated with a DANE-enabled SSL context). The <b>basedomain</b> argument specifies the RFC7671 TLSA base domain, which will be the primary peer reference identifier for certificate name checks. Additional server names can be specified via <a href="../man3/SSL_add1_host.html">SSL_add1_host(3)</a>. The <b>basedomain</b> is used as the default SNI hint if none has yet been specified via <a href="../man3/SSL_set_tlsext_host_name.html">SSL_set_tlsext_host_name(3)</a>.</p> <p>SSL_dane_tlsa_add() may then be called one or more times, to load each of the TLSA records that apply to the remote TLS peer. (This too must be done prior to the beginning of the SSL handshake). The arguments specify the fields of the TLSA record. The <b>data</b> field is provided in binary (wire RDATA) form, not the hexadecimal ASCII presentation form, with an explicit length passed via <b>dlen</b>. The library takes a copy of the <b>data</b> buffer contents and the caller may free the original <b>data</b> buffer when convenient. A return value of 0 indicates that "unusable" TLSA records (with invalid or unsupported parameters) were provided. A negative return value indicates an internal error in processing the record.</p> <p>The caller is expected to check the return value of each SSL_dane_tlsa_add() call and take appropriate action if none are usable or an internal error is encountered in processing some records.</p> <p>If no TLSA records are added successfully, DANE authentication is not enabled, and authentication will be based on any configured traditional trust-anchors; authentication success in this case does not mean that the peer was DANE-authenticated.</p> <p>SSL_get0_dane_authority() can be used to get more detailed information about the matched DANE trust-anchor after successful connection completion. The return value is negative if DANE verification failed (or was not enabled), 0 if an EE TLSA record directly matched the leaf certificate, or a positive number indicating the depth at which a TA record matched an issuer certificate. The complete verified chain can be retrieved via <a href="../man3/SSL_get0_verified_chain.html">SSL_get0_verified_chain(3)</a>. The return value is an index into this verified chain, rather than the list of certificates sent by the peer as returned by <a href="../man3/SSL_get_peer_cert_chain.html">SSL_get_peer_cert_chain(3)</a>.</p> <p>If the <b>mcert</b> argument is not <b>NULL</b> and a TLSA record matched a chain certificate, a pointer to the matching certificate is returned via <b>mcert</b>. The returned address is a short-term internal reference to the certificate and must not be freed by the application. Applications that want to retain access to the certificate can call <a href="../man3/X509_up_ref.html">X509_up_ref(3)</a> to obtain a long-term reference which must then be freed via <a href="../man3/X509_free.html">X509_free(3)</a> once no longer needed.</p> <p>If no TLSA records directly matched any elements of the certificate chain, but a DANE-TA(2) SPKI(1) Full(0) record provided the public key that signed an element of the chain, then that key is returned via <b>mspki</b> argument (if not NULL). In this case the return value is the depth of the top-most element of the validated certificate chain. As with <b>mcert</b> this is a short-term internal reference, and <a href="../man3/EVP_PKEY_up_ref.html">EVP_PKEY_up_ref(3)</a> and <a href="../man3/EVP_PKEY_free.html">EVP_PKEY_free(3)</a> can be used to acquire and release long-term references respectively.</p> <p>SSL_get0_dane_tlsa() can be used to retrieve the fields of the TLSA record that matched the peer certificate chain. The return value indicates the match depth or failure to match just as with SSL_get0_dane_authority(). When the return value is nonnegative, the storage pointed to by the <b>usage</b>, <b>selector</b>, <b>mtype</b> and <b>data</b> parameters is updated to the corresponding TLSA record fields. The <b>data</b> field is in binary wire form, and is therefore not NUL-terminated, its length is returned via the <b>dlen</b> parameter. If any of these parameters is NULL, the corresponding field is not returned. The <b>data</b> parameter is set to a short-term internal-copy of the associated data field and must not be freed by the application. Applications that need long-term access to this field need to copy the content.</p> <p>SSL_CTX_dane_set_flags() and SSL_dane_set_flags() can be used to enable optional DANE verification features. SSL_CTX_dane_clear_flags() and SSL_dane_clear_flags() can be used to disable the same features. The <b>flags</b> argument is a bit mask of the features to enable or disable. The <b>flags</b> set for an <b>SSL_CTX</b> context are copied to each <b>SSL</b> handle associated with that context at the time the handle is created. Subsequent changes in the context's <b>flags</b> have no effect on the <b>flags</b> set for the handle.</p> <p>At present, the only available option is <b>DANE_FLAG_NO_DANE_EE_NAMECHECKS</b> which can be used to disable server name checks when authenticating via DANE-EE(3) TLSA records. For some applications, primarily web browsers, it is not safe to disable name checks due to "unknown key share" attacks, in which a malicious server can convince a client that a connection to a victim server is instead a secure connection to the malicious server. The malicious server may then be able to violate cross-origin scripting restrictions. Thus, despite the text of RFC7671, name checks are by default enabled for DANE-EE(3) TLSA records, and can be disabled in applications where it is safe to do so. In particular, SMTP and XMPP clients should set this option as SRV and MX records already make it possible for a remote domain to redirect client connections to any server of its choice, and in any case SMTP and XMPP clients do not execute scripts downloaded from remote servers.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The functions SSL_CTX_dane_enable(), SSL_CTX_dane_mtype_set(), SSL_dane_enable() and SSL_dane_tlsa_add() return a positive value on success. Negative return values indicate resource problems (out of memory, etc.) in the SSL library, while a return value of <b>0</b> indicates incorrect usage or invalid input, such as an unsupported TLSA record certificate usage, selector or matching type. Invalid input also includes malformed data, either a digest length that does not match the digest algorithm, or a <code>Full(0)</code> (binary ASN.1 DER form) certificate or a public key that fails to parse.</p> <p>The functions SSL_get0_dane_authority() and SSL_get0_dane_tlsa() return a negative value when DANE authentication failed or was not enabled, a nonnegative value indicates the chain depth at which the TLSA record matched a chain certificate, or the depth of the top-most certificate, when the TLSA record is a full public key that is its signer.</p> <p>The functions SSL_CTX_dane_set_flags(), SSL_CTX_dane_clear_flags(), SSL_dane_set_flags() and SSL_dane_clear_flags() return the <b>flags</b> in effect before they were called.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Suppose "smtp.example.com" is the MX host of the domain "example.com", and has DNSSEC-validated TLSA records.

These objects act as containers for implementations of cryptographic algorithms, and support a reference-counted mechanism to allow them to be dynamically loaded in and out of the running application.</p> <p>The cryptographic functionality that can be provided by an <b>ENGINE</b> implementation includes the following abstractions;</p> <pre><code> RSA_METHOD - for providing alternative RSA implementations DSA_METHOD, DH_METHOD, RAND_METHOD, ECDH_METHOD, ECDSA_METHOD, - similarly for other OpenSSL APIs EVP_CIPHER - potentially multiple cipher algorithms (indexed by 'nid') EVP_DIGEST - potentially multiple hash algorithms (indexed by 'nid') key-loading - loading public and/or private EVP_PKEY keys</code></pre> <h2 id="Reference-counting-and-handles">Reference counting and handles</h2> <p>Due to the modular nature of the ENGINE API, pointers to ENGINEs need to be treated as handles - i.e. not only as pointers, but also as references to the underlying ENGINE object. Ie. one should obtain a new reference when making copies of an ENGINE pointer if the copies will be used (and released) independently.</p> <p>ENGINE objects have two levels of reference-counting to match the way in which the objects are used. At the most basic level, each ENGINE pointer is inherently a <b>structural</b> reference - a structural reference is required to use the pointer value at all, as this kind of reference is a guarantee that the structure can not be deallocated until the reference is released.</p> <p>However, a structural reference provides no guarantee that the ENGINE is initialised and able to use any of its cryptographic implementations. Indeed it's quite possible that most ENGINEs will not initialise at all in typical environments, as ENGINEs are typically used to support specialised hardware. To use an ENGINE's functionality, you need a <b>functional</b> reference. This kind of reference can be considered a specialised form of structural reference, because each functional reference implicitly contains a structural reference as well - however to avoid difficult-to-find programming bugs, it is recommended to treat the two kinds of reference independently. If you have a functional reference to an ENGINE, you have a guarantee that the ENGINE has been initialised and is ready to perform cryptographic operations, and will remain initialised until after you have released your reference.</p> <p><i>Structural references</i></p> <p>This basic type of reference is used for instantiating new ENGINEs, iterating across OpenSSL's internal linked-list of loaded ENGINEs, reading information about an ENGINE, etc. Essentially a structural reference is sufficient if you only need to query or manipulate the data of an ENGINE implementation rather than use its functionality.</p> <p>The ENGINE_new() function returns a structural reference to a new (empty) ENGINE object. There are other ENGINE API functions that return structural references such as; ENGINE_by_id(), ENGINE_get_first(), ENGINE_get_last(), ENGINE_get_next(), ENGINE_get_prev(). All structural references should be released by a corresponding to call to the ENGINE_free() function - the ENGINE object itself will only actually be cleaned up and deallocated when the last structural reference is released.</p> <p>It should also be noted that many ENGINE API function calls that accept a structural reference will internally obtain another reference - typically this happens whenever the supplied ENGINE will be needed by OpenSSL after the function has returned. Eg. the function to add a new ENGINE to OpenSSL's internal list is ENGINE_add() - if this function returns success, then OpenSSL will have stored a new structural reference internally so the caller is still responsible for freeing their own reference with ENGINE_free() when they are finished with it. In a similar way, some functions will automatically release the structural reference passed to it if part of the function's job is to do so. Eg. the ENGINE_get_next() and ENGINE_get_prev() functions are used for iterating across the internal ENGINE list - they will return a new structural reference to the next (or previous) ENGINE in the list or NULL if at the end (or beginning) of the list, but in either case the structural reference passed to the function is released on behalf of the caller.</p> <p>To clarify a particular function's handling of references, one should always consult that function's documentation "man" page, or failing that the openssl/engine.h header file includes some hints.</p> <p><i>Functional references</i></p> <p>As mentioned, functional references exist when the cryptographic functionality of an ENGINE is required to be available. A functional reference can be obtained in one of two ways; from an existing structural reference to the required ENGINE, or by asking OpenSSL for the default operational ENGINE for a given cryptographic purpose.</p> <p>To obtain a functional reference from an existing structural reference, call the ENGINE_init() function. This returns zero if the ENGINE was not already operational and couldn't be successfully initialised (e.g. lack of system drivers, no special hardware attached, etc), otherwise it will return nonzero to indicate that the ENGINE is now operational and will have allocated a new <b>functional</b> reference to the ENGINE. All functional references are released by calling ENGINE_finish() (which removes the implicit structural reference as well).</p> <p>The second way to get a functional reference is by asking OpenSSL for a default implementation for a given task, e.g. by ENGINE_get_default_RSA(), ENGINE_get_default_cipher_engine(), etc. These are discussed in the next section, though they are not usually required by application programmers as they are used automatically when creating and using the relevant algorithm-specific types in OpenSSL, such as RSA, DSA, EVP_CIPHER_CTX, etc.</p> <h2 id="Default-implementations">Default implementations</h2> <p>For each supported abstraction, the ENGINE code maintains an internal table of state to control which implementations are available for a given abstraction and which should be used by default. These implementations are registered in the tables and indexed by an 'nid' value, because abstractions like EVP_CIPHER and EVP_DIGEST support many distinct algorithms and modes, and ENGINEs can support arbitrarily many of them. In the case of other abstractions like RSA, DSA, etc, there is only one "algorithm" so all implementations implicitly register using the same 'nid' index.</p> <p>When a default ENGINE is requested for a given abstraction/algorithm/mode, (e.g. when calling RSA_new_method(NULL)), a "get_default" call will be made to the ENGINE subsystem to process the corresponding state table and return a functional reference to an initialised ENGINE whose implementation should be used. If no ENGINE should (or can) be used, it will return NULL and the caller will operate with a NULL ENGINE handle - this usually equates to using the conventional software implementation. In the latter case, OpenSSL will from then on behave the way it used to before the ENGINE API existed.</p> <p>Each state table has a flag to note whether it has processed this "get_default" query since the table was last modified, because to process this question it must iterate across all the registered ENGINEs in the table trying to initialise each of them in turn, in case one of them is operational. If it returns a functional reference to an ENGINE, it will also cache another reference to speed up processing future queries (without needing to iterate across the table). Likewise, it will cache a NULL response if no ENGINE was available so that future queries won't repeat the same iteration unless the state table changes. This behaviour can also be changed; if the ENGINE_TABLE_FLAG_NOINIT flag is set (using ENGINE_set_table_flags()), no attempted initialisations will take place, instead the only way for the state table to return a non-NULL ENGINE to the "get_default" query will be if one is expressly set in the table. Eg. ENGINE_set_default_RSA() does the same job as ENGINE_register_RSA() except that it also sets the state table's cached response for the "get_default" query. In the case of abstractions like EVP_CIPHER, where implementations are indexed by 'nid', these flags and cached-responses are distinct for each 'nid' value.</p> <h2 id="Application-requirements">Application requirements</h2> <p>This section will explain the basic things an application programmer should support to make the most useful elements of the ENGINE functionality available to the user. The first thing to consider is whether the programmer wishes to make alternative ENGINE modules available to the application and user. OpenSSL maintains an internal linked list of "visible" ENGINEs from which it has to operate - at start-up, this list is empty and in fact if an application does not call any ENGINE API calls and it uses static linking against openssl, then the resulting application binary will not contain any alternative ENGINE code at all. So the first consideration is whether any/all available ENGINE implementations should be made visible to OpenSSL - this is controlled by calling the various "load" functions.</p> <p>The fact that ENGINEs are made visible to OpenSSL (and thus are linked into the program and loaded into memory at run-time) does not mean they are "registered" or called into use by OpenSSL automatically - that behaviour is something for the application to control. Some applications will want to allow the user to specify exactly which ENGINE they want used if any is to be used at all. Others may prefer to load all support and have OpenSSL automatically use at run-time any ENGINE that is able to successfully initialise - i.e. to assume that this corresponds to acceleration hardware attached to the machine or some such thing. There are probably numerous other ways in which applications may prefer to handle things, so we will simply illustrate the consequences as they apply to a couple of simple cases and leave developers to consider these and the source code to openssl's builtin utilities as guides.</p> <p>If no ENGINE API functions are called within an application, then OpenSSL will not allocate any internal resources. Prior to OpenSSL 1.1.0, however, if any ENGINEs are loaded, even if not registered or used, it was necessary to call ENGINE_cleanup() before the program exits.</p> <p><i>Using a specific ENGINE implementation</i></p> <p>Here we'll assume an application has been configured by its user or admin to want to use the "ACME" ENGINE if it is available in the version of OpenSSL the application was compiled with. If it is available, it should be used by default for all RSA, DSA, and symmetric cipher operations, otherwise OpenSSL should use its builtin software as per usual. The following code illustrates how to approach this;</p> <pre><code> ENGINE *e; const char *engine_id = "ACME"; ENGINE_load_builtin_engines(); e = ENGINE_by_id(engine_id); if (!e) /* the engine isn't available */ return; if (!ENGINE_init(e)) { /* the engine couldn't initialise, release 'e' */ ENGINE_free(e); return; } if (!ENGINE_set_default_RSA(e)) /* * This should only happen when 'e' can't initialise, but the previous * statement suggests it did. */ abort(); ENGINE_set_default_DSA(e); ENGINE_set_default_ciphers(e); /* Release the functional reference from ENGINE_init() */ ENGINE_finish(e); /* Release the structural reference from ENGINE_by_id() */ ENGINE_free(e);</code></pre> <p><i>Automatically using builtin ENGINE implementations</i></p> <p>Here we'll assume we want to load and register all ENGINE implementations bundled with OpenSSL, such that for any cryptographic algorithm required by OpenSSL - if there is an ENGINE that implements it and can be initialised, it should be used. The following code illustrates how this can work;</p> <pre><code> /* Load all bundled ENGINEs into memory and make them visible */ ENGINE_load_builtin_engines(); /* Register all of them for every algorithm they collectively implement */ ENGINE_register_all_complete();</code></pre> <p>That's all that's required. Eg. the next time OpenSSL tries to set up an RSA key, any bundled ENGINEs that implement RSA_METHOD will be passed to ENGINE_init() and if any of those succeed, that ENGINE will be set as the default for RSA use from then on.</p> <h2 id="Advanced-configuration-support">Advanced configuration support</h2> <p>There is a mechanism supported by the ENGINE framework that allows each ENGINE implementation to define an arbitrary set of configuration "commands" and expose them to OpenSSL and any applications based on OpenSSL. This mechanism is entirely based on the use of name-value pairs and assumes ASCII input (no unicode or UTF for now!), so it is ideal if applications want to provide a transparent way for users to provide arbitrary configuration "directives" directly to such ENGINEs. It is also possible for the application to dynamically interrogate the loaded ENGINE implementations for the names, descriptions, and input flags of their available "control commands", providing a more flexible configuration scheme. However, if the user is expected to know which ENGINE device he/she is using (in the case of specialised hardware, this goes without saying) then applications may not need to concern themselves with discovering the supported control commands and simply prefer to pass settings into ENGINEs exactly as they are provided by the user.</p> <p>Before illustrating how control commands work, it is worth mentioning what they are typically used for. Broadly speaking there are two uses for control commands; the first is to provide the necessary details to the implementation (which may know nothing at all specific to the host system) so that it can be initialised for use. This could include the path to any driver or config files it needs to load, required network addresses, smart-card identifiers, passwords to initialise protected devices, logging information, etc etc. This class of commands typically needs to be passed to an ENGINE <b>before</b> attempting to initialise it, i.e. before calling ENGINE_init(). The other class of commands consist of settings or operations that tweak certain behaviour or cause certain operations to take place, and these commands may work either before or after ENGINE_init(), or in some cases both. ENGINE implementations should provide indications of this in the descriptions attached to builtin control commands and/or in external product documentation.</p> <p><i>Issuing control commands to an ENGINE</i></p> <p>Let's illustrate by example; a function for which the caller supplies the name of the ENGINE it wishes to use, a table of string-pairs for use before initialisation, and another table for use after initialisation. Note that the string-pairs used for control commands consist of a command "name" followed by the command "parameter" - the parameter could be NULL in some cases but the name can not. This function should initialise the ENGINE (issuing the "pre" commands beforehand and the "post" commands afterwards) and set it as the default for everything except RAND and then return a boolean success or failure.</p> <pre><code> int generic_load_engine_fn(const char *engine_id, const char **pre_cmds, int pre_num, const char **post_cmds, int post_num) { ENGINE *e = ENGINE_by_id(engine_id); if (!e) return 0; while (pre_num--) { if (!ENGINE_ctrl_cmd_string(e, pre_cmds[0], pre_cmds[1], 0)) { fprintf(stderr, "Failed command (%s - %s:%s)\n", engine_id, pre_cmds[0], pre_cmds[1] ? pre_cmds[1] : "(NULL)"); ENGINE_free(e); return 0; } pre_cmds += 2; } if (!ENGINE_init(e)) { fprintf(stderr, "Failed initialisation\n"); ENGINE_free(e); return 0; } /* * ENGINE_init() returned a functional reference, so free the structural * reference from ENGINE_by_id(). */ ENGINE_free(e); while (post_num--) { if (!ENGINE_ctrl_cmd_string(e, post_cmds[0], post_cmds[1], 0)) { fprintf(stderr, "Failed command (%s - %s:%s)\n", engine_id, post_cmds[0], post_cmds[1] ? post_cmds[1] : "(NULL)"); ENGINE_finish(e); return 0; } post_cmds += 2; } ENGINE_set_default(e, ENGINE_METHOD_ALL & ~ENGINE_METHOD_RAND); /* Success */ return 1; }</code></pre> <p>Note that ENGINE_ctrl_cmd_string() accepts a boolean argument that can relax the semantics of the function - if set nonzero it will only return failure if the ENGINE supported the given command name but failed while executing it, if the ENGINE doesn't support the command name it will simply return success without doing anything. In this case we assume the user is only supplying commands specific to the given ENGINE so we set this to FALSE.</p> <p><i>Discovering supported control commands</i></p> <p>It is possible to discover at run-time the names, numerical-ids, descriptions and input parameters of the control commands supported by an ENGINE using a structural reference. Note that some control commands are defined by OpenSSL itself and it will intercept and handle these control commands on behalf of the ENGINE, i.e. the ENGINE's ctrl() handler is not used for the control command. openssl/engine.h defines an index, ENGINE_CMD_BASE, that all control commands implemented by ENGINEs should be numbered from. Any command value lower than this symbol is considered a "generic" command is handled directly by the OpenSSL core routines.</p> <p>It is using these "core" control commands that one can discover the control commands implemented by a given ENGINE, specifically the commands:</p> <pre><code> ENGINE_HAS_CTRL_FUNCTION ENGINE_CTRL_GET_FIRST_CMD_TYPE ENGINE_CTRL_GET_NEXT_CMD_TYPE ENGINE_CTRL_GET_CMD_FROM_NAME ENGINE_CTRL_GET_NAME_LEN_FROM_CMD ENGINE_CTRL_GET_NAME_FROM_CMD ENGINE_CTRL_GET_DESC_LEN_FROM_CMD ENGINE_CTRL_GET_DESC_FROM_CMD ENGINE_CTRL_GET_CMD_FLAGS</code></pre> <p>Whilst these commands are automatically processed by the OpenSSL framework code, they use various properties exposed by each ENGINE to process these queries. An ENGINE has 3 properties it exposes that can affect how this behaves; it can supply a ctrl() handler, it can specify ENGINE_FLAGS_MANUAL_CMD_CTRL in the ENGINE's flags, and it can expose an array of control command descriptions. If an ENGINE specifies the ENGINE_FLAGS_MANUAL_CMD_CTRL flag, then it will simply pass all these "core" control commands directly to the ENGINE's ctrl() handler (and thus, it must have supplied one), so it is up to the ENGINE to reply to these "discovery" commands itself. If that flag is not set, then the OpenSSL framework code will work with the following rules:</p> <pre><code> if no ctrl() handler supplied; ENGINE_HAS_CTRL_FUNCTION returns FALSE (zero), all other commands fail. if a ctrl() handler was supplied but no array of control commands; ENGINE_HAS_CTRL_FUNCTION returns TRUE, all other commands fail. if a ctrl() handler and array of control commands was supplied; ENGINE_HAS_CTRL_FUNCTION returns TRUE, all other commands proceed processing ...</code></pre> <p>If the ENGINE's array of control commands is empty then all other commands will fail, otherwise; ENGINE_CTRL_GET_FIRST_CMD_TYPE returns the identifier of the first command supported by the ENGINE, ENGINE_GET_NEXT_CMD_TYPE takes the identifier of a command supported by the ENGINE and returns the next command identifier or fails if there are no more, ENGINE_CMD_FROM_NAME takes a string name for a command and returns the corresponding identifier or fails if no such command name exists, and the remaining commands take a command identifier and return properties of the corresponding commands. All except ENGINE_CTRL_GET_FLAGS return the string length of a command name or description, or populate a supplied character buffer with a copy of the command name or description. ENGINE_CTRL_GET_FLAGS returns a bitwise-OR'd mask of the following possible values:</p> <pre><code> ENGINE_CMD_FLAG_NUMERIC ENGINE_CMD_FLAG_STRING ENGINE_CMD_FLAG_NO_INPUT ENGINE_CMD_FLAG_INTERNAL</code></pre> <p>If the ENGINE_CMD_FLAG_INTERNAL flag is set, then any other flags are purely informational to the caller - this flag will prevent the command being usable for any higher-level ENGINE functions such as ENGINE_ctrl_cmd_string(). "INTERNAL" commands are not intended to be exposed to text-based configuration by applications, administrations, users, etc. These can support arbitrary operations via ENGINE_ctrl(), including passing to and/or from the control commands data of any arbitrary type. These commands are supported in the discovery mechanisms simply to allow applications to determine if an ENGINE supports certain specific commands it might want to use (e.g. application "foo" might query various ENGINEs to see if they implement "FOO_GET_VENDOR_LOGO_GIF" - and ENGINE could therefore decide whether or not to support this "foo"-specific extension).</p> <h1 id="ENVIRONMENT">ENVIRONMENT</h1> <dl> <dt id="OPENSSL_ENGINES"><b>OPENSSL_ENGINES</b></dt> <dd> <p>The path to the engines directory.

The key type used must match <b>keytype</b> if it is not -1. The parameter <b>optype</b> is a mask indicating which operations the control can be applied to. The control command is indicated in <b>cmd</b> and any additional arguments in <b>p1</b> and <b>p2</b>.</p> <p>For <b>cmd</b> = <b>EVP_PKEY_CTRL_SET_MAC_KEY</b>, <b>p1</b> is the length of the MAC key, and <b>p2</b> is MAC key. This is used by Poly1305, SipHash, HMAC and CMAC.</p> <p>Applications will not normally call EVP_PKEY_CTX_ctrl() directly but will instead call one of the algorithm specific macros below.</p> <p>The function EVP_PKEY_CTX_ctrl_uint64() is a wrapper that directly passes a uint64 value as <b>p2</b> to EVP_PKEY_CTX_ctrl().</p> <p>The function EVP_PKEY_CTX_ctrl_str() allows an application to send an algorithm specific control operation to a context <b>ctx</b> in string form. This is intended to be used for options specified on the command line or in text files. The commands supported are documented in the openssl utility command line pages for the option <b>-pkeyopt</b> which is supported by the <b>pkeyutl</b>, <b>genpkey</b> and <b>req</b> commands.</p> <p>The function EVP_PKEY_CTX_md() sends a message digest control operation to the context <b>ctx</b>. The message digest is specified by its name <b>md</b>.</p> <p>All the remaining "functions" are implemented as macros.</p> <p>The EVP_PKEY_CTX_set_signature_md() macro sets the message digest type used in a signature. It can be used in the RSA, DSA and ECDSA algorithms.</p> <p>The EVP_PKEY_CTX_get_signature_md() macro gets the message digest type used in a signature. It can be used in the RSA, DSA and ECDSA algorithms.</p> <p>Key generation typically involves setting up parameters to be used and generating the private and public key data. Some algorithm implementations allow private key data to be set explicitly using the EVP_PKEY_CTX_set_mac_key() macro. In this case key generation is simply the process of setting up the parameters for the key and then setting the raw key data to the value explicitly provided by that macro. Normally applications would call <a href="../man3/EVP_PKEY_new_raw_private_key.html">EVP_PKEY_new_raw_private_key(3)</a> or similar functions instead of this macro.</p> <p>The EVP_PKEY_CTX_set_mac_key() macro can be used with any of the algorithms supported by the <a href="../man3/EVP_PKEY_new_raw_private_key.html">EVP_PKEY_new_raw_private_key(3)</a> function.</p> <h2 id="RSA-parameters">RSA parameters</h2> <p>The EVP_PKEY_CTX_set_rsa_padding() macro sets the RSA padding mode for <b>ctx</b>. The <b>pad</b> parameter can take the value <b>RSA_PKCS1_PADDING</b> for PKCS#1 padding, <b>RSA_SSLV23_PADDING</b> for SSLv23 padding, <b>RSA_NO_PADDING</b> for no padding, <b>RSA_PKCS1_OAEP_PADDING</b> for OAEP padding (encrypt and decrypt only), <b>RSA_X931_PADDING</b> for X9.31 padding (signature operations only) and <b>RSA_PKCS1_PSS_PADDING</b> (sign and verify only).</p> <p>Two RSA padding modes behave differently if EVP_PKEY_CTX_set_signature_md() is used. If this macro is called for PKCS#1 padding the plaintext buffer is an actual digest value and is encapsulated in a DigestInfo structure according to PKCS#1 when signing and this structure is expected (and stripped off) when verifying. If this control is not used with RSA and PKCS#1 padding then the supplied data is used directly and not encapsulated. In the case of X9.31 padding for RSA the algorithm identifier byte is added or checked and removed if this control is called. If it is not called then the first byte of the plaintext buffer is expected to be the algorithm identifier byte.</p> <p>The EVP_PKEY_CTX_get_rsa_padding() macro gets the RSA padding mode for <b>ctx</b>.</p> <p>The EVP_PKEY_CTX_set_rsa_pss_saltlen() macro sets the RSA PSS salt length to <b>len</b>. As its name implies it is only supported for PSS padding. Three special values are supported: <b>RSA_PSS_SALTLEN_DIGEST</b> sets the salt length to the digest length, <b>RSA_PSS_SALTLEN_MAX</b> sets the salt length to the maximum permissible value. When verifying <b>RSA_PSS_SALTLEN_AUTO</b> causes the salt length to be automatically determined based on the <b>PSS</b> block structure. If this macro is not called maximum salt length is used when signing and auto detection when verifying is used by default.</p> <p>The EVP_PKEY_CTX_get_rsa_pss_saltlen() macro gets the RSA PSS salt length for <b>ctx</b>. The padding mode must have been set to <b>RSA_PKCS1_PSS_PADDING</b>.</p> <p>The EVP_PKEY_CTX_set_rsa_keygen_bits() macro sets the RSA key length for RSA key generation to <b>bits</b>. If not specified 1024 bits is used.</p> <p>The EVP_PKEY_CTX_set_rsa_keygen_pubexp() macro sets the public exponent value for RSA key generation to <b>pubexp</b>. Currently it should be an odd integer. The <b>pubexp</b> pointer is used internally by this function so it should not be modified or freed after the call. If not specified 65537 is used.</p> <p>The EVP_PKEY_CTX_set_rsa_keygen_primes() macro sets the number of primes for RSA key generation to <b>primes</b>. If not specified 2 is used.</p> <p>The EVP_PKEY_CTX_set_rsa_mgf1_md() macro sets the MGF1 digest for RSA padding schemes to <b>md</b>. If not explicitly set the signing digest is used. The padding mode must have been set to <b>RSA_PKCS1_OAEP_PADDING</b> or <b>RSA_PKCS1_PSS_PADDING</b>.</p> <p>The EVP_PKEY_CTX_get_rsa_mgf1_md() macro gets the MGF1 digest for <b>ctx</b>. If not explicitly set the signing digest is used. The padding mode must have been set to <b>RSA_PKCS1_OAEP_PADDING</b> or <b>RSA_PKCS1_PSS_PADDING</b>.</p> <p>The EVP_PKEY_CTX_set_rsa_oaep_md() macro sets the message digest type used in RSA OAEP to <b>md</b>. The padding mode must have been set to <b>RSA_PKCS1_OAEP_PADDING</b>.</p> <p>The EVP_PKEY_CTX_get_rsa_oaep_md() macro gets the message digest type used in RSA OAEP to <b>md</b>. The padding mode must have been set to <b>RSA_PKCS1_OAEP_PADDING</b>.</p> <p>The EVP_PKEY_CTX_set0_rsa_oaep_label() macro sets the RSA OAEP label to <b>label</b> and its length to <b>len</b>. If <b>label</b> is NULL or <b>len</b> is 0, the label is cleared. The library takes ownership of the label so the caller should not free the original memory pointed to by <b>label</b>. The padding mode must have been set to <b>RSA_PKCS1_OAEP_PADDING</b>.</p> <p>The EVP_PKEY_CTX_get0_rsa_oaep_label() macro gets the RSA OAEP label to <b>label</b>. The return value is the label length. The padding mode must have been set to <b>RSA_PKCS1_OAEP_PADDING</b>. The resulting pointer is owned by the library and should not be freed by the caller.</p> <h2 id="DSA-parameters">DSA parameters</h2> <p>The EVP_PKEY_CTX_set_dsa_paramgen_bits() macro sets the number of bits used for DSA parameter generation to <b>nbits</b>. If not specified, 1024 is used.</p> <p>The EVP_PKEY_CTX_set_dsa_paramgen_q_bits() macro sets the number of bits in the subprime parameter <b>q</b> for DSA parameter generation to <b>qbits</b>. If not specified, 160 is used. If a digest function is specified below, this parameter is ignored and instead, the number of bits in <b>q</b> matches the size of the digest.</p> <p>The EVP_PKEY_CTX_set_dsa_paramgen_md() macro sets the digest function used for DSA parameter generation to <b>md</b>. If not specified, one of SHA-1, SHA-224, or SHA-256 is selected to match the bit length of <b>q</b> above.</p> <h2 id="DH-parameters">DH parameters</h2> <p>The EVP_PKEY_CTX_set_dh_paramgen_prime_len() macro sets the length of the DH prime parameter <b>p</b> for DH parameter generation. If this macro is not called then 1024 is used. Only accepts lengths greater than or equal to 256.</p> <p>The EVP_PKEY_CTX_set_dh_paramgen_subprime_len() macro sets the length of the DH optional subprime parameter <b>q</b> for DH parameter generation. The default is 256 if the prime is at least 2048 bits long or 160 otherwise. The DH paramgen type must have been set to x9.42.</p> <p>The EVP_PKEY_CTX_set_dh_paramgen_generator() macro sets DH generator to <b>gen</b> for DH parameter generation. If not specified 2 is used.</p> <p>The EVP_PKEY_CTX_set_dh_paramgen_type() macro sets the key type for DH parameter generation. Use 0 for PKCS#3 DH and 1 for X9.42 DH. The default is 0.</p> <p>The EVP_PKEY_CTX_set_dh_pad() macro sets the DH padding mode. If <b>pad</b> is 1 the shared secret is padded with zeros up to the size of the DH prime <b>p</b>. If <b>pad</b> is zero (the default) then no padding is performed.</p> <p>EVP_PKEY_CTX_set_dh_nid() sets the DH parameters to values corresponding to <b>nid</b> as defined in RFC7919. The <b>nid</b> parameter must be <b>NID_ffdhe2048</b>, <b>NID_ffdhe3072</b>, <b>NID_ffdhe4096</b>, <b>NID_ffdhe6144</b>, <b>NID_ffdhe8192</b> or <b>NID_undef</b> to clear the stored value.

This macro can be called during parameter generation. The <b>ctx</b> must have a key type of <b>EVP_PKEY_DHX</b>. The rfc5114 parameter and the nid parameter are mutually exclusive.</p> <h2 id="DH-key-derivation-function-parameters">DH key derivation function parameters</h2> <p>Note that all of the following functions require that the <b>ctx</b> parameter has a private key type of <b>EVP_PKEY_DHX</b>. When using key derivation, the output of EVP_PKEY_derive() is the output of the KDF instead of the DH shared secret. The KDF output is typically used as a Key Encryption Key (KEK) that in turn encrypts a Content Encryption Key (CEK).</p> <p>The EVP_PKEY_CTX_set_dh_kdf_type() macro sets the key derivation function type to <b>kdf</b> for DH key derivation.

For EC parameter generation this macro must be called or an error occurs because there is no default curve. This function can also be called to set the curve explicitly when generating an EC key.</p> <p>The EVP_PKEY_CTX_set_ec_param_enc() macro sets the EC parameter encoding to <b>param_enc</b> when generating EC parameters or an EC key. The encoding can be <b>OPENSSL_EC_EXPLICIT_CURVE</b> for explicit parameters (the default in versions of OpenSSL before 1.1.0) or <b>OPENSSL_EC_NAMED_CURVE</b> to use named curve form. For maximum compatibility the named curve form should be used. Note: the <b>OPENSSL_EC_NAMED_CURVE</b> value was added in OpenSSL 1.1.0; previous versions should use 0 instead.</p> <h2 id="ECDH-parameters">ECDH parameters</h2> <p>The EVP_PKEY_CTX_set_ecdh_cofactor_mode() macro sets the cofactor mode to <b>cofactor_mode</b> for ECDH key derivation. Possible values are 1 to enable cofactor key derivation, 0 to disable it and -1 to clear the stored cofactor mode and fallback to the private key cofactor mode.</p> <p>The EVP_PKEY_CTX_get_ecdh_cofactor_mode() macro returns the cofactor mode for <b>ctx</b> used for ECDH key derivation.

This parameter is optional and corresponds to the shared info in X9.63 terms. The library takes ownership of the user key material so the caller should not free the original memory pointed to by <b>ukm</b>.</p> <p>The EVP_PKEY_CTX_get0_ecdh_kdf_ukm() macro gets the user key material for <b>ctx</b>. The return value is the user key material length.

The EVP_PKEY_CTX_set1_id() sets an ID pointed by <b>id</b> with the length <b>id_len</b> to the library. The library takes a copy of the id so that the caller can safely free the original memory pointed to by <b>id</b>. The EVP_PKEY_CTX_get1_id_len() macro returns the length of the ID set via a previous call to EVP_PKEY_CTX_set1_id(). The length is usually used to allocate adequate memory for further calls to EVP_PKEY_CTX_get1_id(). The EVP_PKEY_CTX_get1_id() macro returns the previously set ID value to caller in <b>id</b>. The caller should allocate adequate memory space for the <b>id</b> before calling EVP_PKEY_CTX_get1_id().</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>EVP_PKEY_CTX_ctrl() and its macros return a positive value for success and 0 or a negative value for failure.

OPENSSL_zalloc() calls memset() to zero the memory before returning.</p> <p>OPENSSL_clear_realloc() and OPENSSL_clear_free() should be used when the buffer at <b>addr</b> holds sensitive information. The old buffer is filled with zero's by calling OPENSSL_cleanse() before ultimately calling OPENSSL_free().</p> <p>OPENSSL_cleanse() fills <b>ptr</b> of size <b>len</b> with a string of 0's. Use OPENSSL_cleanse() with care if the memory is a mapping of a file. If the storage controller uses write compression, then it's possible that sensitive tail bytes will survive zeroization because the block of zeros will be compressed. If the storage controller uses wear leveling, then the old sensitive data will not be overwritten; rather, a block of 0's will be written at a new physical location.</p> <p>OPENSSL_strdup(), OPENSSL_strndup() and OPENSSL_memdup() are like the equivalent C functions, except that memory is allocated by calling the OPENSSL_malloc() and should be released by calling OPENSSL_free().</p> <p>OPENSSL_strlcpy(), OPENSSL_strlcat() and OPENSSL_strnlen() are equivalents of the common C library functions and are provided for portability.</p> <p>OPENSSL_hexstr2buf() parses <b>str</b> as a hex string and returns a pointer to the parsed value. The memory is allocated by calling OPENSSL_malloc() and should be released by calling OPENSSL_free(). If <b>len</b> is not NULL, it is filled in with the output length. Colons between two-character hex "bytes" are ignored. An odd number of hex digits is an error.</p> <p>OPENSSL_buf2hexstr() takes the specified buffer and length, and returns a hex string for value, or NULL on error. <b>Buffer</b> cannot be NULL; if <b>len</b> is 0 an empty string is returned.</p> <p>OPENSSL_hexchar2int() converts a character to the hexadecimal equivalent, or returns -1 on error.</p> <p>If no allocations have been done, it is possible to "swap out" the default implementations for OPENSSL_malloc(), OPENSSL_realloc and OPENSSL_free() and replace them with alternate versions (hooks). CRYPTO_get_mem_functions() function fills in the given arguments with the function pointers for the current implementations. With CRYPTO_set_mem_functions(), you can specify a different set of functions. If any of <b>m</b>, <b>r</b>, or <b>f</b> are NULL, then the function is not changed.</p> <p>The default implementation can include some debugging capability (if enabled at build-time). This adds some overhead by keeping a list of all memory allocations, and removes items from the list when they are free'd. This is most useful for identifying memory leaks. CRYPTO_set_mem_debug() turns this tracking on and off. In order to have any effect, is must be called before any of the allocation functions (e.g., CRYPTO_malloc()) are called, and is therefore normally one of the first lines of main() in an application. CRYPTO_mem_ctrl() provides fine-grained control of memory leak tracking. To enable tracking call CRYPTO_mem_ctrl() with a <b>mode</b> argument of the <b>CRYPTO_MEM_CHECK_ON</b>. To disable tracking call CRYPTO_mem_ctrl() with a <b>mode</b> argument of the <b>CRYPTO_MEM_CHECK_OFF</b>.</p> <p>While checking memory, it can be useful to store additional context about what is being done. For example, identifying the field names when parsing a complicated data structure. OPENSSL_mem_debug_push() (which calls CRYPTO_mem_debug_push()) attaches an identifying string to the allocation stack. This must be a global or other static string; it is not copied. OPENSSL_mem_debug_pop() removes identifying state from the stack.</p> <p>At the end of the program, calling CRYPTO_mem_leaks() or CRYPTO_mem_leaks_fp() will report all "leaked" memory, writing it to the specified BIO <b>b</b> or FILE <b>fp</b>. These functions return 1 if there are no leaks, 0 if there are leaks and -1 if an error occurred.</p> <p>CRYPTO_mem_leaks_cb() does the same as CRYPTO_mem_leaks(), but instead of writing to a given BIO, the callback function is called for each output string with the string, length, and userdata <b>u</b> as the callback parameters.</p> <p>If the library is built with the <code>crypto-mdebug</code> option, then one function, CRYPTO_get_alloc_counts(), and two additional environment variables, <b>OPENSSL_MALLOC_FAILURES</b> and <b>OPENSSL_MALLOC_FD</b>, are available.</p> <p>The function CRYPTO_get_alloc_counts() fills in the number of times each of CRYPTO_malloc(), CRYPTO_realloc(), and CRYPTO_free() have been called, into the values pointed to by <b>mcount</b>, <b>rcount</b>, and <b>fcount</b>, respectively. If a pointer is NULL, then the corresponding count is not stored.</p> <p>The variable <b>OPENSSL_MALLOC_FAILURES</b> controls how often allocations should fail. It is a set of fields separated by semicolons, which each field is a count (defaulting to zero) and an optional atsign and percentage (defaulting to 100). If the count is zero, then it lasts forever. For example, <code>100;@25</code> or <code>100@0;0@25</code> means the first 100 allocations pass, then all other allocations (until the program exits or crashes) have a 25% chance of failing.</p> <p>If the variable <b>OPENSSL_MALLOC_FD</b> is parsed as a positive integer, then it is taken as an open file descriptor, and a record of all allocations is written to that descriptor. If an allocation will fail, and the platform supports it, then a backtrace will be written to the descriptor. This can be useful because a malloc may fail but not be checked, and problems will only occur later. The following example in classic shell syntax shows how to use this (will not work on all platforms):</p> <pre><code> OPENSSL_MALLOC_FAILURES='200;@10' export OPENSSL_MALLOC_FAILURES OPENSSL_MALLOC_FD=3 export OPENSSL_MALLOC_FD ...app invocation... 3>/tmp/log$$</code></pre> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>OPENSSL_malloc_init(), OPENSSL_free(), OPENSSL_clear_free() CRYPTO_free(), CRYPTO_clear_free() and CRYPTO_get_mem_functions() return no value.</p> <p>CRYPTO_mem_leaks(), CRYPTO_mem_leaks_fp() and CRYPTO_mem_leaks_cb() return 1 if there are no leaks, 0 if there are leaks and -1 if an error occurred.</p> <p>OPENSSL_malloc(), OPENSSL_zalloc(), OPENSSL_realloc(), OPENSSL_clear_realloc(), CRYPTO_malloc(), CRYPTO_zalloc(), CRYPTO_realloc(), CRYPTO_clear_realloc(), OPENSSL_buf2hexstr(), OPENSSL_hexstr2buf(), OPENSSL_strdup(), and OPENSSL_strndup() return a pointer to allocated memory or NULL on error.</p> <p>CRYPTO_set_mem_functions() and CRYPTO_set_mem_debug() return 1 on success or 0 on failure (almost always because allocations have already happened).</p> <p>CRYPTO_mem_ctrl() returns -1 if an error occurred, otherwise the previous value of the mode.</p> <p>OPENSSL_mem_debug_push() and OPENSSL_mem_debug_pop() return 1 on success or 0 on failure.</p> <h1 id="NOTES">NOTES</h1> <p>While it's permitted to swap out only a few and not all the functions with CRYPTO_set_mem_functions(), it's recommended to swap them all out at once. <i>This applies specially if OpenSSL was built with the configuration option</i> <code>crypto-mdebug</code> <i>enabled. In case, swapping out only, say, the malloc() implementation is outright dangerous.</i></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2016-2020 The OpenSSL Project Authors.

any of the OpenSSL datatypes, such as <i>X509_CRL</i>. The function parameters <i>ppin</i> and <i>ppout</i> are generally either both named <i>pp</i> in the headers, or <i>in</i> and <i>out</i>.</p> <p>These functions convert OpenSSL objects to and from their ASN.1/DER encoding. Unlike the C structures which can have pointers to sub-objects within, the DER is a serialized encoding, suitable for sending over the network, writing to a file, and so on.</p> <p>d2i_TYPE() attempts to decode <b>len</b> bytes at <b>*ppin</b>. If successful a pointer to the <b>TYPE</b> structure is returned and <b>*ppin</b> is incremented to the byte following the parsed data. If <b>a</b> is not <b>NULL</b> then a pointer to the returned structure is also written to <b>*a</b>. If an error occurred then <b>NULL</b> is returned.</p> <p>On a successful return, if <b>*a</b> is not <b>NULL</b> then it is assumed that <b>*a</b> contains a valid <b>TYPE</b> structure and an attempt is made to reuse it. This "reuse" capability is present for historical compatibility but its use is <b>strongly discouraged</b> (see BUGS below, and the discussion in the RETURN VALUES section).</p> <p>d2i_TYPE_bio() is similar to d2i_TYPE() except it attempts to parse data from BIO <b>bp</b>.</p> <p>d2i_TYPE_fp() is similar to d2i_TYPE() except it attempts to parse data from FILE pointer <b>fp</b>.</p> <p>i2d_TYPE() encodes the structure pointed to by <b>a</b> into DER format. If <b>ppout</b> is not <b>NULL</b>, it writes the DER encoded data to the buffer at <b>*ppout</b>, and increments it to point after the data just written. If the return value is negative an error occurred, otherwise it returns the length of the encoded data.</p> <p>If <b>*ppout</b> is <b>NULL</b> memory will be allocated for a buffer and the encoded data written to it. In this case <b>*ppout</b> is not incremented and it points to the start of the data just written.</p> <p>i2d_TYPE_bio() is similar to i2d_TYPE() except it writes the encoding of the structure <b>a</b> to BIO <b>bp</b> and it returns 1 for success and 0 for failure.</p> <p>i2d_TYPE_fp() is similar to i2d_TYPE() except it writes the encoding of the structure <b>a</b> to BIO <b>bp</b> and it returns 1 for success and 0 for failure.</p> <p>These routines do not encrypt private keys and therefore offer no security; use <a href="../man3/PEM_write_PrivateKey.html">PEM_write_PrivateKey(3)</a> or similar for writing to files.</p> <h1 id="NOTES">NOTES</h1> <p>The letters <b>i</b> and <b>d</b> in <b>i2d_TYPE</b> stand for "internal" (that is, an internal C structure) and "DER" respectively. So <b>i2d_TYPE</b> converts from internal to DER.</p> <p>The functions can also understand <b>BER</b> forms.</p> <p>The actual TYPE structure passed to i2d_TYPE() must be a valid populated <b>TYPE</b> structure -- it <b>cannot</b> simply be fed with an empty structure such as that returned by TYPE_new().</p> <p>The encoded data is in binary form and may contain embedded zeros. Therefore, any FILE pointers or BIOs should be opened in binary mode. Functions such as strlen() will <b>not</b> return the correct length of the encoded structure.</p> <p>The ways that <b>*ppin</b> and <b>*ppout</b> are incremented after the operation can trap the unwary. See the <b>WARNINGS</b> section for some common errors. The reason for this-auto increment behaviour is to reflect a typical usage of ASN1 functions: after one structure is encoded or decoded another will be processed after it.</p> <p>The following points about the data types might be useful:</p> <dl> <dt id="ASN1_OBJECT"><b>ASN1_OBJECT</b></dt> <dd> <p>Represents an ASN1 OBJECT IDENTIFIER.</p> </dd> <dt id="DHparams"><b>DHparams</b></dt> <dd> <p>Represents a PKCS#3 DH parameters structure.</p> </dd> <dt id="DHxparams"><b>DHxparams</b></dt> <dd> <p>Represents an ANSI X9.42 DH parameters structure.</p> </dd> <dt id="DSA_PUBKEY"><b>DSA_PUBKEY</b></dt> <dd> <p>Represents a DSA public key using a <b>SubjectPublicKeyInfo</b> structure.</p> </dd> <dt id="DSAPublicKey-DSAPrivateKey"><b>DSAPublicKey, DSAPrivateKey</b></dt> <dd> <p>Use a non-standard OpenSSL format and should be avoided; use <b>DSA_PUBKEY</b>, <b>PEM_write_PrivateKey(3)</b>, or similar instead.</p> </dd> <dt id="ECDSA_SIG"><b>ECDSA_SIG</b></dt> <dd> <p>Represents an ECDSA signature.</p> </dd> <dt id="RSAPublicKey"><b>RSAPublicKey</b></dt> <dd> <p>Represents a PKCS#1 RSA public key structure.</p> </dd> <dt id="X509_ALGOR"><b>X509_ALGOR</b></dt> <dd> <p>Represents an <b>AlgorithmIdentifier</b> structure as used in IETF RFC 6960 and elsewhere.</p> </dd> <dt id="X509_Name"><b>X509_Name</b></dt> <dd> <p>Represents a <b>Name</b> type as used for subject and issuer names in IETF RFC 6960 and elsewhere.</p> </dd> <dt id="X509_REQ"><b>X509_REQ</b></dt> <dd> <p>Represents a PKCS#10 certificate request.</p> </dd> <dt id="X509_SIG"><b>X509_SIG</b></dt> <dd> <p>Represents the <b>DigestInfo</b> structure defined in PKCS#1 and PKCS#7.</p> </dd> </dl> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>d2i_TYPE(), d2i_TYPE_bio() and d2i_TYPE_fp() return a valid <b>TYPE</b> structure or <b>NULL</b> if an error occurs.

OPENSSL_free(buf);</code></pre> <p>This code will result in <b>buf</b> apparently containing garbage because it was incremented after the call to point after the data just written. Also <b>buf</b> will no longer contain the pointer allocated by OPENSSL_malloc() and the subsequent call to OPENSSL_free() is likely to crash.</p> <p>Another trap to avoid is misuse of the <b>a</b> argument to d2i_TYPE():</p> <pre><code> X509 *x; if (d2i_X509(&x, &p, len) == NULL) /* error */</code></pre> <p>This will probably crash somewhere in d2i_X509(). The reason for this is that the variable <b>x</b> is uninitialized and an attempt will be made to interpret its (invalid) value as an <b>X509</b> structure, typically causing a segmentation violation. If <b>x</b> is set to NULL first then this will not happen.</p> <h1 id="BUGS">BUGS</h1> <p>In some versions of OpenSSL the "reuse" behaviour of d2i_TYPE() when <b>*a</b> is valid is broken and some parts of the reused structure may persist if they are not present in the new one. Additionally, in versions of OpenSSL prior to 1.1.0, when the "reuse" behaviour is used and an error occurs the behaviour is inconsistent. Some functions behaved as described here, while some did not free <b>*a</b> on error and did not set <b>*a</b> to NULL.</p> <p>As a result of the above issues the "reuse" behaviour is strongly discouraged.</p> <p>i2d_TYPE() will not return an error in many versions of OpenSSL, if mandatory fields are not initialized due to a programming error then the encoded structure may contain invalid data or omit the fields entirely and will not be parsed by d2i_TYPE(). This may be fixed in future so code should not assume that i2d_TYPE() will always succeed.</p> <p>Any function which encodes a structure (i2d_TYPE(), i2d_TYPE() or i2d_TYPE()) may return a stale encoding if the structure has been modified after deserialization or previous serialization. This is because some objects cache the encoding for efficiency reasons.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 1998-2021 The OpenSSL Project Authors.

For example if a call to BIO_read_ex() on a socket BIO returns 0 and BIO_should_retry() is false then the cause will be that the connection closed. A similar condition on a file BIO will mean that it has reached EOF. Some BIO types may place additional information on the error queue. For more details see the individual BIO type manual pages.</p> <p>If the underlying I/O structure is in a blocking mode almost all current BIO types will not request a retry, because the underlying I/O calls will not. If the application knows that the BIO type will never signal a retry then it need not call BIO_should_retry() after a failed BIO I/O call. This is typically done with file BIOs.</p> <p>SSL BIOs are the only current exception to this rule: they can request a retry even if the underlying I/O structure is blocking, if a handshake occurs during a call to BIO_read(). An application can retry the failed call immediately or avoid this situation by setting SSL_MODE_AUTO_RETRY on the underlying SSL structure.</p> <p>While an application may retry a failed non blocking call immediately this is likely to be very inefficient because the call will fail repeatedly until data can be processed or is available. An application will normally wait until the necessary condition is satisfied. How this is done depends on the underlying I/O structure.</p> <p>For example if the cause is ultimately a socket and BIO_should_read() is true then a call to select() may be made to wait until data is available and then retry the BIO operation. By combining the retry conditions of several non blocking BIOs in a single select() call it is possible to service several BIOs in a single thread, though the performance may be poor if SSL BIOs are present because long delays can occur during the initial handshake process.</p> <p>It is possible for a BIO to block indefinitely if the underlying I/O structure cannot process or return any data. This depends on the behaviour of the platforms I/O functions. This is often not desirable: one solution is to use non blocking I/O and use a timeout on the select() (or equivalent) call.</p> <h1 id="BUGS">BUGS</h1> <p>The OpenSSL ASN1 functions cannot gracefully deal with non blocking I/O: that is they cannot retry after a partial read or write.

A triplet contains three members, <b>r</b>, <b>d</b> and <b>t</b>. <b>r</b> is the additional prime besides <b>p</b> and <b>q</b>. <b>d</b> and <b>t</b> are the exponent and coefficient for CRT calculations.</p> <p>The <b>n</b>, <b>e</b> and <b>d</b> parameters can be obtained by calling RSA_get0_key(). If they have not been set yet, then <b>*n</b>, <b>*e</b> and <b>*d</b> will be set to NULL. Otherwise, they are set to pointers to their respective values. These point directly to the internal representations of the values and therefore should not be freed by the caller.</p> <p>The <b>n</b>, <b>e</b> and <b>d</b> parameter values can be set by calling RSA_set0_key() and passing the new values for <b>n</b>, <b>e</b> and <b>d</b> as parameters to the function. The values <b>n</b> and <b>e</b> must be non-NULL the first time this function is called on a given RSA object. The value <b>d</b> may be NULL. On subsequent calls any of these values may be NULL which means the corresponding RSA field is left untouched. Calling this function transfers the memory management of the values to the RSA object, and therefore the values that have been passed in should not be freed by the caller after this function has been called.</p> <p>In a similar fashion, the <b>p</b> and <b>q</b> parameters can be obtained and set with RSA_get0_factors() and RSA_set0_factors(), and the <b>dmp1</b>, <b>dmq1</b> and <b>iqmp</b> parameters can be obtained and set with RSA_get0_crt_params() and RSA_set0_crt_params().</p> <p>For RSA_get0_key(), RSA_get0_factors(), and RSA_get0_crt_params(), NULL value BIGNUM ** output parameters are permitted. The functions ignore NULL parameters but return values for other, non-NULL, parameters.</p> <p>For multi-prime RSA, RSA_get0_multi_prime_factors() and RSA_get0_multi_prime_params() can be used to obtain other primes and related CRT parameters. The return values are stored in an array of <b>BIGNUM *</b>. RSA_set0_multi_prime_params() sets a collect of multi-prime 'triplet' members (prime, exponent and coefficient) into an RSA object.</p> <p>Any of the values <b>n</b>, <b>e</b>, <b>d</b>, <b>p</b>, <b>q</b>, <b>dmp1</b>, <b>dmq1</b>, and <b>iqmp</b> can also be retrieved separately by the corresponding function RSA_get0_n(), RSA_get0_e(), RSA_get0_d(), RSA_get0_p(), RSA_get0_q(), RSA_get0_dmp1(), RSA_get0_dmq1(), and RSA_get0_iqmp(), respectively.</p> <p>RSA_get0_pss_params() is used to retrieve the RSA-PSS parameters.</p> <p>RSA_set_flags() sets the flags in the <b>flags</b> parameter on the RSA object. Multiple flags can be passed in one go (bitwise ORed together). Any flags that are already set are left set. RSA_test_flags() tests to see whether the flags passed in the <b>flags</b> parameter are currently set in the RSA object. Multiple flags can be tested in one go. All flags that are currently set are returned, or zero if none of the flags are set. RSA_clear_flags() clears the specified flags within the RSA object.</p> <p>RSA_get0_engine() returns a handle to the ENGINE that has been set for this RSA object, or NULL if no such ENGINE has been set.</p> <p>RSA_get_version() returns the version of an RSA object <b>r</b>.</p> <h1 id="NOTES">NOTES</h1> <p>Values retrieved with RSA_get0_key() are owned by the RSA object used in the call and may therefore <i>not</i> be passed to RSA_set0_key().

The first is the generation of a <i>DES_key_schedule</i> from a key, the second is the actual encryption. A DES key is of type <i>DES_cblock</i>. This type consists of 8 bytes with odd parity. The least significant bit in each byte is the parity bit. The key schedule is an expanded form of the key; it is used to speed the encryption process.</p> <p>DES_random_key() generates a random key. The random generator must be seeded when calling this function. If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to external circumstances (see <a href="../man7/RAND.html">RAND(7)</a>), the operation will fail. If the function fails, 0 is returned.</p> <p>Before a DES key can be used, it must be converted into the architecture dependent <i>DES_key_schedule</i> via the DES_set_key_checked() or DES_set_key_unchecked() function.</p> <p>DES_set_key_checked() will check that the key passed is of odd parity and is not a weak or semi-weak key. If the parity is wrong, then -1 is returned. If the key is a weak key, then -2 is returned. If an error is returned, the key schedule is not generated.</p> <p>DES_set_key() works like DES_set_key_checked() if the <i>DES_check_key</i> flag is nonzero, otherwise like DES_set_key_unchecked(). These functions are available for compatibility; it is recommended to use a function that does not depend on a global variable.</p> <p>DES_set_odd_parity() sets the parity of the passed <i>key</i> to odd.</p> <p>DES_is_weak_key() returns 1 if the passed key is a weak key, 0 if it is ok.</p> <p>The following routines mostly operate on an input and output stream of <i>DES_cblock</i>s.</p> <p>DES_ecb_encrypt() is the basic DES encryption routine that encrypts or decrypts a single 8-byte <i>DES_cblock</i> in <i>electronic code book</i> (ECB) mode. It always transforms the input data, pointed to by <i>input</i>, into the output data, pointed to by the <i>output</i> argument. If the <i>encrypt</i> argument is nonzero (DES_ENCRYPT), the <i>input</i> (cleartext) is encrypted in to the <i>output</i> (ciphertext) using the key_schedule specified by the <i>schedule</i> argument, previously set via <i>DES_set_key</i>. If <i>encrypt</i> is zero (DES_DECRYPT), the <i>input</i> (now ciphertext) is decrypted into the <i>output</i> (now cleartext). Input and output may overlap. DES_ecb_encrypt() does not return a value.</p> <p>DES_ecb3_encrypt() encrypts/decrypts the <i>input</i> block by using three-key Triple-DES encryption in ECB mode. This involves encrypting the input with <i>ks1</i>, decrypting with the key schedule <i>ks2</i>, and then encrypting with <i>ks3</i>. This routine greatly reduces the chances of brute force breaking of DES and has the advantage of if <i>ks1</i>, <i>ks2</i> and <i>ks3</i> are the same, it is equivalent to just encryption using ECB mode and <i>ks1</i> as the key.</p> <p>The macro DES_ecb2_encrypt() is provided to perform two-key Triple-DES encryption by using <i>ks1</i> for the final encryption.</p> <p>DES_ncbc_encrypt() encrypts/decrypts using the <i>cipher-block-chaining</i> (CBC) mode of DES. If the <i>encrypt</i> argument is nonzero, the routine cipher-block-chain encrypts the cleartext data pointed to by the <i>input</i> argument into the ciphertext pointed to by the <i>output</i> argument, using the key schedule provided by the <i>schedule</i> argument, and initialization vector provided by the <i>ivec</i> argument. If the <i>length</i> argument is not an integral multiple of eight bytes, the last block is copied to a temporary area and zero filled. The output is always an integral multiple of eight bytes.</p> <p>DES_xcbc_encrypt() is RSA's DESX mode of DES. It uses <i>inw</i> and <i>outw</i> to 'whiten' the encryption. <i>inw</i> and <i>outw</i> are secret (unlike the iv) and are as such, part of the key. So the key is sort of 24 bytes. This is much better than CBC DES.</p> <p>DES_ede3_cbc_encrypt() implements outer triple CBC DES encryption with three keys. This means that each DES operation inside the CBC mode is <code>C=E(ks3,D(ks2,E(ks1,M)))</code>. This mode is used by SSL.</p> <p>The DES_ede2_cbc_encrypt() macro implements two-key Triple-DES by reusing <i>ks1</i> for the final encryption. <code>C=E(ks1,D(ks2,E(ks1,M)))</code>. This form of Triple-DES is used by the RSAREF library.</p> <p>DES_pcbc_encrypt() encrypts/decrypts using the propagating cipher block chaining mode used by Kerberos v4. Its parameters are the same as DES_ncbc_encrypt().</p> <p>DES_cfb_encrypt() encrypts/decrypts using cipher feedback mode. This method takes an array of characters as input and outputs an array of characters. It does not require any padding to 8 character groups. Note: the <i>ivec</i> variable is changed and the new changed value needs to be passed to the next call to this function. Since this function runs a complete DES ECB encryption per <i>numbits</i>, this function is only suggested for use when sending a small number of characters.</p> <p>DES_cfb64_encrypt() implements CFB mode of DES with 64-bit feedback. Why is this useful you ask? Because this routine will allow you to encrypt an arbitrary number of bytes, without 8 byte padding. Each call to this routine will encrypt the input bytes to output and then update ivec and num. num contains 'how far' we are though ivec. If this does not make much sense, read more about CFB mode of DES.</p> <p>DES_ede3_cfb64_encrypt() and DES_ede2_cfb64_encrypt() is the same as DES_cfb64_encrypt() except that Triple-DES is used.</p> <p>DES_ofb_encrypt() encrypts using output feedback mode. This method takes an array of characters as input and outputs an array of characters. It does not require any padding to 8 character groups. Note: the <i>ivec</i> variable is changed and the new changed value needs to be passed to the next call to this function. Since this function runs a complete DES ECB encryption per <i>numbits</i>, this function is only suggested for use when sending a small number of characters.</p> <p>DES_ofb64_encrypt() is the same as DES_cfb64_encrypt() using Output Feed Back mode.</p> <p>DES_ede3_ofb64_encrypt() and DES_ede2_ofb64_encrypt() is the same as DES_ofb64_encrypt(), using Triple-DES.</p> <p>The following functions are included in the DES library for compatibility with the MIT Kerberos library.</p> <p>DES_cbc_cksum() produces an 8 byte checksum based on the input stream (via CBC encryption). The last 4 bytes of the checksum are returned and the complete 8 bytes are placed in <i>output</i>. This function is used by Kerberos v4. Other applications should use <a href="../man3/EVP_DigestInit.html">EVP_DigestInit(3)</a> etc. instead.</p> <p>DES_quad_cksum() is a Kerberos v4 function. It returns a 4 byte checksum from the input bytes. The algorithm can be iterated over the input, depending on <i>out_count</i>, 1, 2, 3 or 4 times. If <i>output</i> is non-NULL, the 8 bytes generated by each pass are written into <i>output</i>.</p> <p>The following are DES-based transformations:</p> <p>DES_fcrypt() is a fast version of the Unix crypt(3) function. This version takes only a small amount of space relative to other fast crypt() implementations. This is different to the normal crypt() in that the third parameter is the buffer that the return value is written into. It needs to be at least 14 bytes long. This function is thread safe, unlike the normal crypt().</p> <p>DES_crypt() is a faster replacement for the normal system crypt(). This function calls DES_fcrypt() with a static array passed as the third parameter. This mostly emulates the normal non-thread-safe semantics of crypt(3). The <b>salt</b> must be two ASCII characters.</p> <p>The values returned by DES_fcrypt() and DES_crypt() are terminated by NUL character.</p> <p>DES_enc_write() writes <i>len</i> bytes to file descriptor <i>fd</i> from buffer <i>buf</i>. The data is encrypted via <i>pcbc_encrypt</i> (default) using <i>sched</i> for the key and <i>iv</i> as a starting vector. The actual data send down <i>fd</i> consists of 4 bytes (in network byte order) containing the length of the following encrypted data. The encrypted data then follows, padded with random data out to a multiple of 8 bytes.</p> <h1 id="BUGS">BUGS</h1> <p>DES_cbc_encrypt() does not modify <b>ivec</b>; use DES_ncbc_encrypt() instead.</p> <p>DES_cfb_encrypt() and DES_ofb_encrypt() operates on input of 8 bits. What this means is that if you set numbits to 12, and length to 2, the first 12 bits will come from the 1st input byte and the low half of the second input byte. The second 12 bits will have the low 8 bits taken from the 3rd input byte and the top 4 bits taken from the 4th input byte. The same holds for output. This function has been implemented this way because most people will be using a multiple of 8 and because once you get into pulling bytes input bytes apart things get ugly!</p> <p>DES_string_to_key() is available for backward compatibility with the MIT library. New applications should use a cryptographic hash function. The same applies for DES_string_to_2key().</p> <h1 id="NOTES">NOTES</h1> <p>The <b>des</b> library was written to be source code compatible with the MIT Kerberos library.</p> <p>Applications should use the higher level functions <a href="../man3/EVP_EncryptInit.html">EVP_EncryptInit(3)</a> etc. instead of calling these functions directly.</p> <p>Single-key DES is insecure due to its short key size.

The specific structures are:</p> <pre><code> APP BIO DH DRBG DSA EC_KEY ENGINE RSA SSL SSL_CTX SSL_SESSION UI UI_METHOD X509 X509_STORE X509_STORE_CTX</code></pre> <p>Each is identified by an <b>CRYPTO_EX_INDEX_xxx</b> define in the <b>crypto.h</b> header file. In addition, <b>CRYPTO_EX_INDEX_APP</b> is reserved for applications to use this facility for their own structures.</p> <p>The API described here is used by OpenSSL to manipulate exdata for specific structures. Since the application data can be anything at all it is passed and retrieved as a <b>void *</b> type.</p> <p>The <b>CRYPTO_EX_DATA</b> type is opaque. To initialize the exdata part of a structure, call CRYPTO_new_ex_data(). This is only necessary for <b>CRYPTO_EX_INDEX_APP</b> objects.</p> <p>Exdata types are identified by an <b>index</b>, an integer guaranteed to be unique within structures for the lifetime of the program. Applications using exdata typically call <b>CRYPTO_get_ex_new_index</b> at startup, and store the result in a global variable, or write a wrapper function to provide lazy evaluation. The <b>class_index</b> should be one of the <b>CRYPTO_EX_INDEX_xxx</b> values. The <b>argl</b> and <b>argp</b> parameters are saved to be passed to the callbacks but are otherwise not used. In order to transparently manipulate exdata, three callbacks must be provided. The semantics of those callbacks are described below.</p> <p>When copying or releasing objects with exdata, the callback functions are called in increasing order of their <b>index</b> value.</p> <p>If a dynamic library can be unloaded, it should call CRYPTO_free_ex_index() when this is done. This will replace the callbacks with no-ops so that applications don't crash. Any existing exdata will be leaked.</p> <p>To set or get the exdata on an object, the appropriate type-specific routine must be used. This is because the containing structure is opaque and the <b>CRYPTO_EX_DATA</b> field is not accessible. In both API's, the <b>idx</b> parameter should be an already-created index value.</p> <p>When setting exdata, the pointer specified with a particular index is saved, and returned on a subsequent "get" call. If the application is going to release the data, it must make sure to set a <b>NULL</b> value at the index, to avoid likely double-free crashes.</p> <p>The function <b>CRYPTO_free_ex_data</b> is used to free all exdata attached to a structure. The appropriate type-specific routine must be used. The <b>class_index</b> identifies the structure type, the <b>obj</b> is a pointer to the actual structure, and <b>r</b> is a pointer to the structure's exdata field.</p> <h2 id="Callback-Functions">Callback Functions</h2> <p>This section describes how the callback functions are used. Applications that are defining their own exdata using <b>CYPRTO_EX_INDEX_APP</b> must call them as described here.</p> <p>When a structure is initially allocated (such as RSA_new()) then the new_func() is called for every defined index. There is no requirement that the entire parent, or containing, structure has been set up. The new_func() is typically used only to allocate memory to store the exdata, and perhaps an "initialized" flag within that memory. The exdata value should be set by calling CRYPTO_set_ex_data().</p> <p>When a structure is free'd (such as SSL_CTX_free()) then the free_func() is called for every defined index. Again, the state of the parent structure is not guaranteed. The free_func() may be called with a NULL pointer.</p> <p>Both new_func() and free_func() take the same parameters. The <b>parent</b> is the pointer to the structure that contains the exdata. The <b>ptr</b> is the current exdata item; for new_func() this will typically be NULL. The <b>r</b> parameter is a pointer to the exdata field of the object. The <b>idx</b> is the index and is the value returned when the callbacks were initially registered via CRYPTO_get_ex_new_index() and can be used if the same callback handles different types of exdata.</p> <p>dup_func() is called when a structure is being copied. This is only done for <b>SSL</b>, <b>SSL_SESSION</b>, <b>EC_KEY</b> objects and <b>BIO</b> chains via BIO_dup_chain(). The <b>to</b> and <b>from</b> parameters are pointers to the destination and source <b>CRYPTO_EX_DATA</b> structures, respectively. The <b>from_d</b> parameter needs to be cast to a <b>void **pptr</b> as the API has currently the wrong signature; that will be changed in a future version. The <b>*pptr</b> is a pointer to the source exdata. When the dup_func() returns, the value in <b>*pptr</b> is copied to the destination ex_data. If the pointer contained in <b>*pptr</b> is not modified by the dup_func(), then both <b>to</b> and <b>from</b> will point to the same data. The <b>idx</b>, <b>argl</b> and <b>argp</b> parameters are as described for the other two callbacks. If the dup_func() returns <b>0</b> the whole CRYPTO_dup_ex_data() will fail.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>CRYPTO_get_ex_new_index() returns a new index or -1 on failure.</p> <p>CRYPTO_free_ex_index() and CRYPTO_set_ex_data() return 1 on success or 0 on failure.</p> <p>CRYPTO_get_ex_data() returns the application data or NULL on failure; note that NULL may be a valid value.</p> <p>dup_func() should return 0 for failure and 1 for success.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2015-2019 The OpenSSL Project Authors.

This function should be called after all operations using a cipher are complete so sensitive information does not remain in memory.</p> <p>EVP_EncryptInit_ex() sets up cipher context <b>ctx</b> for encryption with cipher <b>type</b> from ENGINE <b>impl</b>. <b>ctx</b> must be created before calling this function. <b>type</b> is normally supplied by a function such as EVP_aes_256_cbc(). If <b>impl</b> is NULL then the default implementation is used. <b>key</b> is the symmetric key to use and <b>iv</b> is the IV to use (if necessary), the actual number of bytes used for the key and IV depends on the cipher. It is possible to set all parameters to NULL except <b>type</b> in an initial call and supply the remaining parameters in subsequent calls, all of which have <b>type</b> set to NULL. This is done when the default cipher parameters are not appropriate.</p> <p>EVP_EncryptUpdate() encrypts <b>inl</b> bytes from the buffer <b>in</b> and writes the encrypted version to <b>out</b>. This function can be called multiple times to encrypt successive blocks of data. The amount of data written depends on the block alignment of the encrypted data. For most ciphers and modes, the amount of data written can be anything from zero bytes to (inl + cipher_block_size - 1) bytes. For wrap cipher modes, the amount of data written can be anything from zero bytes to (inl + cipher_block_size) bytes. For stream ciphers, the amount of data written can be anything from zero bytes to inl bytes. Thus, <b>out</b> should contain sufficient room for the operation being performed. The actual number of bytes written is placed in <b>outl</b>. It also checks if <b>in</b> and <b>out</b> are partially overlapping, and if they are 0 is returned to indicate failure.</p> <p>If padding is enabled (the default) then EVP_EncryptFinal_ex() encrypts the "final" data, that is any data that remains in a partial block. It uses standard block padding (aka PKCS padding) as described in the NOTES section, below. The encrypted final data is written to <b>out</b> which should have sufficient space for one cipher block. The number of bytes written is placed in <b>outl</b>. After this function is called the encryption operation is finished and no further calls to EVP_EncryptUpdate() should be made.</p> <p>If padding is disabled then EVP_EncryptFinal_ex() will not encrypt any more data and it will return an error if any data remains in a partial block: that is if the total data length is not a multiple of the block size.</p> <p>EVP_DecryptInit_ex(), EVP_DecryptUpdate() and EVP_DecryptFinal_ex() are the corresponding decryption operations. EVP_DecryptFinal() will return an error code if padding is enabled and the final block is not correctly formatted. The parameters and restrictions are identical to the encryption operations except that if padding is enabled the decrypted data buffer <b>out</b> passed to EVP_DecryptUpdate() should have sufficient room for (<b>inl</b> + cipher_block_size) bytes unless the cipher block size is 1 in which case <b>inl</b> bytes is sufficient.</p> <p>EVP_CipherInit_ex(), EVP_CipherUpdate() and EVP_CipherFinal_ex() are functions that can be used for decryption or encryption. The operation performed depends on the value of the <b>enc</b> parameter. It should be set to 1 for encryption, 0 for decryption and -1 to leave the value unchanged (the actual value of 'enc' being supplied in a previous call).</p> <p>EVP_CIPHER_CTX_reset() clears all information from a cipher context and free up any allocated memory associate with it, except the <b>ctx</b> itself. This function should be called anytime <b>ctx</b> is to be reused for another EVP_CipherInit() / EVP_CipherUpdate() / EVP_CipherFinal() series of calls.</p> <p>EVP_EncryptInit(), EVP_DecryptInit() and EVP_CipherInit() behave in a similar way to EVP_EncryptInit_ex(), EVP_DecryptInit_ex() and EVP_CipherInit_ex() except they always use the default cipher implementation.</p> <p>EVP_EncryptFinal(), EVP_DecryptFinal() and EVP_CipherFinal() are identical to EVP_EncryptFinal_ex(), EVP_DecryptFinal_ex() and EVP_CipherFinal_ex(). In previous releases they also cleaned up the <b>ctx</b>, but this is no longer done and EVP_CIPHER_CTX_clean() must be called to free any context resources.</p> <p>EVP_get_cipherbyname(), EVP_get_cipherbynid() and EVP_get_cipherbyobj() return an EVP_CIPHER structure when passed a cipher name, a NID or an ASN1_OBJECT structure.</p> <p>EVP_CIPHER_nid() and EVP_CIPHER_CTX_nid() return the NID of a cipher when passed an <b>EVP_CIPHER</b> or <b>EVP_CIPHER_CTX</b> structure. The actual NID value is an internal value which may not have a corresponding OBJECT IDENTIFIER.</p> <p>EVP_CIPHER_CTX_set_padding() enables or disables padding. This function should be called after the context is set up for encryption or decryption with EVP_EncryptInit_ex(), EVP_DecryptInit_ex() or EVP_CipherInit_ex(). By default encryption operations are padded using standard block padding and the padding is checked and removed when decrypting. If the <b>pad</b> parameter is zero then no padding is performed, the total amount of data encrypted or decrypted must then be a multiple of the block size or an error will occur.</p> <p>EVP_CIPHER_key_length() and EVP_CIPHER_CTX_key_length() return the key length of a cipher when passed an <b>EVP_CIPHER</b> or <b>EVP_CIPHER_CTX</b> structure. The constant <b>EVP_MAX_KEY_LENGTH</b> is the maximum key length for all ciphers. Note: although EVP_CIPHER_key_length() is fixed for a given cipher, the value of EVP_CIPHER_CTX_key_length() may be different for variable key length ciphers.</p> <p>EVP_CIPHER_CTX_set_key_length() sets the key length of the cipher ctx. If the cipher is a fixed length cipher then attempting to set the key length to any value other than the fixed value is an error.</p> <p>EVP_CIPHER_iv_length() and EVP_CIPHER_CTX_iv_length() return the IV length of a cipher when passed an <b>EVP_CIPHER</b> or <b>EVP_CIPHER_CTX</b>. It will return zero if the cipher does not use an IV. The constant <b>EVP_MAX_IV_LENGTH</b> is the maximum IV length for all ciphers.</p> <p>EVP_CIPHER_block_size() and EVP_CIPHER_CTX_block_size() return the block size of a cipher when passed an <b>EVP_CIPHER</b> or <b>EVP_CIPHER_CTX</b> structure. The constant <b>EVP_MAX_BLOCK_LENGTH</b> is also the maximum block length for all ciphers.</p> <p>EVP_CIPHER_type() and EVP_CIPHER_CTX_type() return the type of the passed cipher or context. This "type" is the actual NID of the cipher OBJECT IDENTIFIER as such it ignores the cipher parameters and 40 bit RC2 and 128 bit RC2 have the same NID. If the cipher does not have an object identifier or does not have ASN1 support this function will return <b>NID_undef</b>.</p> <p>EVP_CIPHER_CTX_cipher() returns the <b>EVP_CIPHER</b> structure when passed an <b>EVP_CIPHER_CTX</b> structure.</p> <p>EVP_CIPHER_mode() and EVP_CIPHER_CTX_mode() return the block cipher mode: EVP_CIPH_ECB_MODE, EVP_CIPH_CBC_MODE, EVP_CIPH_CFB_MODE, EVP_CIPH_OFB_MODE, EVP_CIPH_CTR_MODE, EVP_CIPH_GCM_MODE, EVP_CIPH_CCM_MODE, EVP_CIPH_XTS_MODE, EVP_CIPH_WRAP_MODE or EVP_CIPH_OCB_MODE. If the cipher is a stream cipher then EVP_CIPH_STREAM_CIPHER is returned.</p> <p>EVP_CIPHER_param_to_asn1() sets the AlgorithmIdentifier "parameter" based on the passed cipher. This will typically include any parameters and an IV. The cipher IV (if any) must be set when this call is made. This call should be made before the cipher is actually "used" (before any EVP_EncryptUpdate(), EVP_DecryptUpdate() calls for example). This function may fail if the cipher does not have any ASN1 support.</p> <p>EVP_CIPHER_asn1_to_param() sets the cipher parameters based on an ASN1 AlgorithmIdentifier "parameter". The precise effect depends on the cipher In the case of RC2, for example, it will set the IV and effective key length. This function should be called after the base cipher type is set but before the key is set. For example EVP_CipherInit() will be called with the IV and key set to NULL, EVP_CIPHER_asn1_to_param() will be called and finally EVP_CipherInit() again with all parameters except the key set to NULL. It is possible for this function to fail if the cipher does not have any ASN1 support or the parameters cannot be set (for example the RC2 effective key length is not supported.</p> <p>EVP_CIPHER_CTX_ctrl() allows various cipher specific parameters to be determined and set.</p> <p>EVP_CIPHER_CTX_rand_key() generates a random key of the appropriate length based on the cipher context. The EVP_CIPHER can provide its own random key generation routine to support keys of a specific form. <b>Key</b> must point to a buffer at least as big as the value returned by EVP_CIPHER_CTX_key_length().</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>EVP_CIPHER_CTX_new() returns a pointer to a newly created <b>EVP_CIPHER_CTX</b> for success and <b>NULL</b> for failure.</p> <p>EVP_EncryptInit_ex(), EVP_EncryptUpdate() and EVP_EncryptFinal_ex() return 1 for success and 0 for failure.</p> <p>EVP_DecryptInit_ex() and EVP_DecryptUpdate() return 1 for success and 0 for failure. EVP_DecryptFinal_ex() returns 0 if the decrypt failed or 1 for success.</p> <p>EVP_CipherInit_ex() and EVP_CipherUpdate() return 1 for success and 0 for failure. EVP_CipherFinal_ex() returns 0 for a decryption failure or 1 for success.</p> <p>EVP_CIPHER_CTX_reset() returns 1 for success and 0 for failure.</p> <p>EVP_get_cipherbyname(), EVP_get_cipherbynid() and EVP_get_cipherbyobj() return an <b>EVP_CIPHER</b> structure or NULL on error.</p> <p>EVP_CIPHER_nid() and EVP_CIPHER_CTX_nid() return a NID.</p> <p>EVP_CIPHER_block_size() and EVP_CIPHER_CTX_block_size() return the block size.</p> <p>EVP_CIPHER_key_length() and EVP_CIPHER_CTX_key_length() return the key length.</p> <p>EVP_CIPHER_CTX_set_padding() always returns 1.</p> <p>EVP_CIPHER_iv_length() and EVP_CIPHER_CTX_iv_length() return the IV length, zero if the cipher does not use an IV and a negative value on error.</p> <p>EVP_CIPHER_type() and EVP_CIPHER_CTX_type() return the NID of the cipher's OBJECT IDENTIFIER or NID_undef if it has no defined OBJECT IDENTIFIER.</p> <p>EVP_CIPHER_CTX_cipher() returns an <b>EVP_CIPHER</b> structure.</p> <p>EVP_CIPHER_param_to_asn1() and EVP_CIPHER_asn1_to_param() return greater than zero for success and zero or a negative number on failure.</p> <p>EVP_CIPHER_CTX_rand_key() returns 1 for success.</p> <h1 id="CIPHER-LISTING">CIPHER LISTING</h1> <p>All algorithms have a fixed key length unless otherwise stated.</p> <p>Refer to <a href="#SEE-ALSO">"SEE ALSO"</a> for the full list of ciphers available through the EVP interface.</p> <dl> <dt id="EVP_enc_null">EVP_enc_null()</dt> <dd> <p>Null cipher: does nothing.</p> </dd> </dl> <h1 id="AEAD-Interface">AEAD Interface</h1> <p>The EVP interface for Authenticated Encryption with Associated Data (AEAD) modes are subtly altered and several additional <i>ctrl</i> operations are supported depending on the mode specified.</p> <p>To specify additional authenticated data (AAD), a call to EVP_CipherUpdate(), EVP_EncryptUpdate() or EVP_DecryptUpdate() should be made with the output parameter <b>out</b> set to <b>NULL</b>.</p> <p>When decrypting, the return value of EVP_DecryptFinal() or EVP_CipherFinal() indicates whether the operation was successful.

This is because the code then becomes transparent to the cipher used and much more flexible. Additionally, the <b>EVP</b> interface will ensure the use of platform specific cryptographic acceleration such as AES-NI (the low-level interfaces do not provide the guarantee).</p> <p>PKCS padding works by adding <b>n</b> padding bytes of value <b>n</b> to make the total length of the encrypted data a multiple of the block size. Padding is always added so if the data is already a multiple of the block size <b>n</b> will equal the block size. For example if the block size is 8 and 11 bytes are to be encrypted then 5 padding bytes of value 5 will be added.</p> <p>When decrypting the final block is checked to see if it has the correct form.</p> <p>Although the decryption operation can produce an error if padding is enabled, it is not a strong test that the input data or key is correct. A random block has better than 1 in 256 chance of being of the correct format and problems with the input data earlier on will not produce a final decrypt error.</p> <p>If padding is disabled then the decryption operation will always succeed if the total amount of data decrypted is a multiple of the block size.</p> <p>The functions EVP_EncryptInit(), EVP_EncryptFinal(), EVP_DecryptInit(), EVP_CipherInit() and EVP_CipherFinal() are obsolete but are retained for compatibility with existing code. New code should use EVP_EncryptInit_ex(), EVP_EncryptFinal_ex(), EVP_DecryptInit_ex(), EVP_DecryptFinal_ex(), EVP_CipherInit_ex() and EVP_CipherFinal_ex() because they can reuse an existing context without allocating and freeing it up on each call.</p> <p>There are some differences between functions EVP_CipherInit() and EVP_CipherInit_ex(), significant in some circumstances. EVP_CipherInit() fills the passed context object with zeros. As a consequence, EVP_CipherInit() does not allow step-by-step initialization of the ctx when the <i>key</i> and <i>iv</i> are passed in separate calls. It also means that the flags set for the CTX are removed, and it is especially important for the <b>EVP_CIPHER_CTX_FLAG_WRAP_ALLOW</b> flag treated specially in EVP_CipherInit_ex().</p> <p>EVP_get_cipherbynid(), and EVP_get_cipherbyobj() are implemented as macros.</p> <h1 id="BUGS">BUGS</h1> <p><b>EVP_MAX_KEY_LENGTH</b> and <b>EVP_MAX_IV_LENGTH</b> only refer to the internal ciphers with default key lengths.

In the case of EC_POINTs_make_affine the value <b>num</b> provides the number of points in the array <b>points</b> to be forced.</p> <p>EC_POINT_mul is a convenient interface to EC_POINTs_mul: it calculates the value generator * <b>n</b> + <b>q</b> * <b>m</b> and stores the result in <b>r</b>. The value <b>n</b> may be NULL in which case the result is just <b>q</b> * <b>m</b> (variable point multiplication). Alternatively, both <b>q</b> and <b>m</b> may be NULL, and <b>n</b> non-NULL, in which case the result is just generator * <b>n</b> (fixed point multiplication). When performing a single fixed or variable point multiplication, the underlying implementation uses a constant time algorithm, when the input scalar (either <b>n</b> or <b>m</b>) is in the range [0, ec_group_order).</p> <p>EC_POINTs_mul calculates the value generator * <b>n</b> + <b>q[0]</b> * <b>m[0]</b> + ... + <b>q[num-1]</b> * <b>m[num-1]</b>.

When performing a fixed point multiplication (<b>n</b> is non-NULL and <b>num</b> is 0) or a variable point multiplication (<b>n</b> is NULL and <b>num</b> is 1), the underlying implementation uses a constant time algorithm, when the input scalar (either <b>n</b> or <b>m[0]</b>) is in the range [0, ec_group_order).</p> <p>The function EC_GROUP_precompute_mult stores multiples of the generator for faster point multiplication, whilst EC_GROUP_have_precompute_mult tests whether precomputation has already been done.

This explicitly means, that e.g. the special method used during the session will be kept for the next handshake. So if the session was a TLSv1 session, a SSL client object will use a TLSv1 client method for the next handshake and a SSL server object will use a TLSv1 server method, even if TLS_*_methods were chosen on startup.

The session id is an arbitrary sequence of bytes. The length of the session id is between 1 and 32 bytes. The session id is not security critical but must be unique for the server. Additionally, the session id is transmitted in the clear when reusing the session so it must not contain sensitive information.</p> <p>Without a callback being set, an OpenSSL server will generate a unique session id from pseudo random numbers of the maximum possible length. Using the callback function, the session id can be changed to contain additional information like e.g. a host id in order to improve load balancing or external caching techniques.</p> <p>The callback function receives a pointer to the memory location to put <b>id</b> into and a pointer to the maximum allowed length <b>id_len</b>. The buffer at location <b>id</b> is only guaranteed to have the size <b>id_len</b>. The callback is only allowed to generate a shorter id and reduce <b>id_len</b>; the callback <b>must never</b> increase <b>id_len</b> or write to the location <b>id</b> exceeding the given limit.</p> <p>The location <b>id</b> is filled with 0x00 before the callback is called, so the callback may only fill part of the possible length and leave <b>id_len</b> untouched while maintaining reproducibility.</p> <p>Since the sessions must be distinguished, session ids must be unique. Without the callback a random number is used, so that the probability of generating the same session id is extremely small (2^256 for SSLv3/TLSv1). In order to assure the uniqueness of the generated session id, the callback must call SSL_has_matching_session_id() and generate another id if a conflict occurs. If an id conflict is not resolved, the handshake will fail. If the application codes e.g. a unique host id, a unique process number, and a unique sequence number into the session id, uniqueness could easily be achieved without randomness added (it should however be taken care that no confidential information is leaked this way). If the application can not guarantee uniqueness, it is recommended to use the maximum <b>id_len</b> and fill in the bytes not used to code special information with random data to avoid collisions.</p> <p>SSL_has_matching_session_id() will only query the internal session cache, not the external one. Since the session id is generated before the handshake is completed, it is not immediately added to the cache. If another thread is using the same internal session cache, a race condition can occur in that another thread generates the same session id. Collisions can also occur when using an external session cache, since the external cache is not tested with SSL_has_matching_session_id() and the same race condition applies.</p> <p>The callback must return 0 if it cannot generate a session id for whatever reason and return 1 on success.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CTX_set_generate_session_id() and SSL_set_generate_session_id() always return 1.</p> <p>SSL_has_matching_session_id() returns 1 if another session with the same id is already in the cache.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>The callback function listed will generate a session id with the server id given, and will fill the rest with pseudo random bytes:</p> <pre><code> const char session_id_prefix = "www-18"; #define MAX_SESSION_ID_ATTEMPTS 10 static int generate_session_id(SSL *ssl, unsigned char *id, unsigned int *id_len) { unsigned int count = 0; do { RAND_pseudo_bytes(id, *id_len); /* * Prefix the session_id with the required prefix.

The reference count is set to <b>1</b>.</p> <p>EVP_PKEY_up_ref() increments the reference count of <b>key</b>.</p> <p>EVP_PKEY_free() decrements the reference count of <b>key</b> and, if the reference count is zero, frees it up. If <b>key</b> is NULL, nothing is done.</p> <p>EVP_PKEY_new_raw_private_key() allocates a new <b>EVP_PKEY</b>. If <b>e</b> is non-NULL then the new <b>EVP_PKEY</b> structure is associated with the engine <b>e</b>. The <b>type</b> argument indicates what kind of key this is. The value should be a NID for a public key algorithm that supports raw private keys, i.e. one of <b>EVP_PKEY_HMAC</b>, <b>EVP_PKEY_POLY1305</b>, <b>EVP_PKEY_SIPHASH</b>, <b>EVP_PKEY_X25519</b>, <b>EVP_PKEY_ED25519</b>, <b>EVP_PKEY_X448</b> or <b>EVP_PKEY_ED448</b>. <b>key</b> points to the raw private key data for this <b>EVP_PKEY</b> which should be of length <b>keylen</b>.

The <b>EVP_PKEY</b> structure will be initialised without any private key information. Algorithm types that support raw public keys are <b>EVP_PKEY_X25519</b>, <b>EVP_PKEY_ED25519</b>, <b>EVP_PKEY_X448</b> or <b>EVP_PKEY_ED448</b>.</p> <p>EVP_PKEY_new_CMAC_key() works in the same way as EVP_PKEY_new_raw_private_key() except it is only for the <b>EVP_PKEY_CMAC</b> algorithm type. In addition to the raw private key data, it also takes a cipher algorithm to be used during creation of a CMAC in the <b>cipher</b> argument. The cipher should be a standard encryption only cipher. For example AEAD and XTS ciphers should not be used.</p> <p>EVP_PKEY_new_mac_key() works in the same way as EVP_PKEY_new_raw_private_key(). New applications should use EVP_PKEY_new_raw_private_key() instead.</p> <p>EVP_PKEY_get_raw_private_key() fills the buffer provided by <b>priv</b> with raw private key data.

If the buffer <b>priv</b> is NULL then <b>*len</b> is populated with the number of bytes required to hold the key. The calling application is responsible for ensuring that the buffer is large enough to receive the private key data. This function only works for algorithms that support raw private keys.

This is a wrapper round the platform's TCP/IP socket accept routines.</p> <p>Using accept BIOs, TCP/IP connections can be accepted and data transferred using only BIO routines. In this way any platform specific operations are hidden by the BIO abstraction.</p> <p>Read and write operations on an accept BIO will perform I/O on the underlying connection. If no connection is established and the port (see below) is set up properly then the BIO waits for an incoming connection.</p> <p>Accept BIOs support BIO_puts() but not BIO_gets().</p> <p>If the close flag is set on an accept BIO then any active connection on that chain is shutdown and the socket closed when the BIO is freed.</p> <p>Calling BIO_reset() on an accept BIO will close any active connection and reset the BIO into a state where it awaits another incoming connection.</p> <p>BIO_get_fd() and BIO_set_fd() can be called to retrieve or set the accept socket. See <a href="../man3/BIO_s_fd.html">BIO_s_fd(3)</a></p> <p>BIO_set_accept_name() uses the string <b>name</b> to set the accept name. The name is represented as a string of the form "host:port", where "host" is the interface to use and "port" is the port. The host can be "*" or empty which is interpreted as meaning any interface. If the host is an IPv6 address, it has to be enclosed in brackets, for example "[::1]:https". "port" has the same syntax as the port specified in BIO_set_conn_port() for connect BIOs, that is it can be a numerical port string or a string to lookup using getservbyname() and a string table.</p> <p>BIO_set_accept_port() uses the string <b>port</b> to set the accept port. "port" has the same syntax as the port specified in BIO_set_conn_port() for connect BIOs, that is it can be a numerical port string or a string to lookup using getservbyname() and a string table.</p> <p>BIO_new_accept() combines BIO_new() and BIO_set_accept_name() into a single call: that is it creates a new accept BIO with port <b>host_port</b>.</p> <p>BIO_set_nbio_accept() sets the accept socket to blocking mode (the default) if <b>n</b> is 0 or non blocking mode if <b>n</b> is 1.</p> <p>BIO_set_accept_bios() can be used to set a chain of BIOs which will be duplicated and prepended to the chain when an incoming connection is received. This is useful if, for example, a buffering or SSL BIO is required for each connection. The chain of BIOs must not be freed after this call, they will be automatically freed when the accept BIO is freed.</p> <p>BIO_set_bind_mode() and BIO_get_bind_mode() set and retrieve the current bind mode. If <b>BIO_BIND_NORMAL</b> (the default) is set then another socket cannot be bound to the same port. If <b>BIO_BIND_REUSEADDR</b> is set then other sockets can bind to the same port. If <b>BIO_BIND_REUSEADDR_IF_UNUSED</b> is set then and attempt is first made to use BIO_BIN_NORMAL, if this fails and the port is not in use then a second attempt is made using <b>BIO_BIND_REUSEADDR</b>.</p> <p>BIO_do_accept() serves two functions. When it is first called, after the accept BIO has been setup, it will attempt to create the accept socket and bind an address to it. Second and subsequent calls to BIO_do_accept() will await an incoming connection, or request a retry in non blocking mode.</p> <h1 id="NOTES">NOTES</h1> <p>When an accept BIO is at the end of a chain it will await an incoming connection before processing I/O calls. When an accept BIO is not at then end of a chain it passes I/O calls to the next BIO in the chain.</p> <p>When a connection is established a new socket BIO is created for the connection and appended to the chain. That is the chain is now accept->socket. This effectively means that attempting I/O on an initial accept socket will await an incoming connection then perform I/O on it.</p> <p>If any additional BIOs have been set using BIO_set_accept_bios() then they are placed between the socket and the accept BIO, that is the chain will be accept->otherbios->socket.</p> <p>If a server wishes to process multiple connections (as is normally the case) then the accept BIO must be made available for further incoming connections. This can be done by waiting for a connection and then calling:</p> <pre><code> connection = BIO_pop(accept);</code></pre> <p>After this call <b>connection</b> will contain a BIO for the recently established connection and <b>accept</b> will now be a single BIO again which can be used to await further incoming connections. If no further connections will be accepted the <b>accept</b> can be freed using BIO_free().</p> <p>If only a single connection will be processed it is possible to perform I/O using the accept BIO itself. This is often undesirable however because the accept BIO will still accept additional incoming connections. This can be resolved by using BIO_pop() (see above) and freeing up the accept BIO after the initial connection.</p> <p>If the underlying accept socket is nonblocking and BIO_do_accept() is called to await an incoming connection it is possible for BIO_should_io_special() with the reason BIO_RR_ACCEPT. If this happens then it is an indication that an accept attempt would block: the application should take appropriate action to wait until the underlying socket has accepted a connection and retry the call.</p> <p>BIO_set_accept_name(), BIO_get_accept_name(), BIO_set_accept_port(), BIO_get_accept_port(), BIO_set_nbio_accept(), BIO_set_accept_bios(), BIO_get_peer_name(), BIO_get_peer_port(), BIO_get_accept_ip_family(), BIO_set_accept_ip_family(), BIO_set_bind_mode(), BIO_get_bind_mode() and BIO_do_accept() are macros.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>BIO_do_accept(), BIO_set_accept_name(), BIO_set_accept_port(), BIO_set_nbio_accept(), BIO_set_accept_bios(), BIO_set_accept_ip_family(), and BIO_set_bind_mode() return 1 for success and 0 or -1 for failure.</p> <p>BIO_get_accept_name() returns the accept name or NULL on error.

This is accomplished by setting a built-in CT validation callback. The behaviour of the callback is determined by the <b>validation_mode</b> argument, which can be either of <b>SSL_CT_VALIDATION_PERMISSIVE</b> or <b>SSL_CT_VALIDATION_STRICT</b> as described below.</p> <p>If <b>validation_mode</b> is equal to <b>SSL_CT_VALIDATION_STRICT</b>, then in a full TLS handshake with the verification mode set to <b>SSL_VERIFY_PEER</b>, if the peer presents no valid SCTs the handshake will be aborted. If the verification mode is <b>SSL_VERIFY_NONE</b>, the handshake will continue despite lack of valid SCTs. However, in that case if the verification status before the built-in callback was <b>X509_V_OK</b> it will be set to <b>X509_V_ERR_NO_VALID_SCTS</b> after the callback. Applications can call <a href="../man3/SSL_get_verify_result.html">SSL_get_verify_result(3)</a> to check the status at handshake completion, even after session resumption since the verification status is part of the saved session state. See <a href="../man3/SSL_set_verify.html">SSL_set_verify(3)</a>, <SSL_get_verify_result(3)>, <a href="../man3/SSL_session_reused.html">SSL_session_reused(3)</a>.</p> <p>If <b>validation_mode</b> is equal to <b>SSL_CT_VALIDATION_PERMISSIVE</b>, then the handshake continues, and the verification status is not modified, regardless of the validation status of any SCTs. The application can still inspect the validation status of the SCTs at handshake completion. Note that with session resumption there will not be any SCTs presented during the handshake. Therefore, in applications that delay SCT policy enforcement until after handshake completion, such delayed SCT checks should only be performed when the session is not resumed.</p> <p>SSL_set_ct_validation_callback() and SSL_CTX_set_ct_validation_callback() register a custom callback that may implement a different policy than either of the above. This callback can examine the peer's SCTs and determine whether they are sufficient to allow the connection to continue. The TLS handshake is aborted if the verification mode is not <b>SSL_VERIFY_NONE</b> and the callback returns a non-positive result.</p> <p>An arbitrary callback context argument, <b>arg</b>, can be passed in when setting the callback. This will be passed to the callback whenever it is invoked. Ownership of this context remains with the caller.</p> <p>If no callback is set, SCTs will not be requested and Certificate Transparency validation will not occur.</p> <p>No callback will be invoked when the peer presents no certificate, e.g. by employing an anonymous (aNULL) cipher suite. In that case the handshake continues as it would had no callback been requested. Callbacks are also not invoked when the peer certificate chain is invalid or validated via DANE-TA(2) or DANE-EE(3) TLSA records which use a private X.509 PKI, or no X.509 PKI at all, respectively. Clients that require SCTs are expected to not have enabled any aNULL ciphers nor to have specified server verification via DANE-TA(2) or DANE-EE(3) TLSA records.</p> <p>SSL_disable_ct() and SSL_CTX_disable_ct() turn off CT processing, whether enabled via the built-in or the custom callbacks, by setting a NULL callback. These may be implemented as macros.</p> <p>SSL_ct_is_enabled() and SSL_CTX_ct_is_enabled() return 1 if CT processing is enabled via either SSL_enable_ct() or a non-null custom callback, and 0 otherwise.</p> <h1 id="NOTES">NOTES</h1> <p>When SCT processing is enabled, OCSP stapling will be enabled. This is because one possible source of SCTs is the OCSP response from a server.</p> <p>The time returned by SSL_SESSION_get_time() will be used to evaluate whether any presented SCTs have timestamps that are in the future (and therefore invalid).</p> <h1 id="RESTRICTIONS">RESTRICTIONS</h1> <p>Certificate Transparency validation cannot be enabled and so a callback cannot be set if a custom client extension handler has been registered to handle SCT extensions (<b>TLSEXT_TYPE_signed_certificate_timestamp</b>).</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_enable_ct(), SSL_CTX_enable_ct(), SSL_CTX_set_ct_validation_callback() and SSL_set_ct_validation_callback() return 1 if the <b>callback</b> is successfully set.

The following descriptions apply in the case of the built-in procedure. An application provided procedure also has access to the verify depth information and the verify_callback() function, but the way this information is used may be different.</p> <p>SSL_CTX_set_verify_depth() and SSL_set_verify_depth() set a limit on the number of certificates between the end-entity and trust-anchor certificates. Neither the end-entity nor the trust-anchor certificates count against <b>depth</b>. If the certificate chain needed to reach a trusted issuer is longer than <b>depth+2</b>, X509_V_ERR_CERT_CHAIN_TOO_LONG will be issued. The depth count is "level 0:peer certificate", "level 1: CA certificate", "level 2: higher level CA certificate", and so on. Setting the maximum depth to 2 allows the levels 0, 1, 2 and 3 (0 being the end-entity and 3 the trust-anchor). The default depth limit is 100, allowing for the peer certificate, at most 100 intermediate CA certificates and a final trust anchor certificate.</p> <p>The <b>verify_callback</b> function is used to control the behaviour when the SSL_VERIFY_PEER flag is set. It must be supplied by the application and receives two arguments: <b>preverify_ok</b> indicates, whether the verification of the certificate in question was passed (preverify_ok=1) or not (preverify_ok=0). <b>x509_ctx</b> is a pointer to the complete context used for the certificate chain verification.</p> <p>The certificate chain is checked starting with the deepest nesting level (the root CA certificate) and worked upward to the peer's certificate. At each level signatures and issuer attributes are checked. Whenever a verification error is found, the error number is stored in <b>x509_ctx</b> and <b>verify_callback</b> is called with <b>preverify_ok</b>=0. By applying X509_CTX_store_* functions <b>verify_callback</b> can locate the certificate in question and perform additional steps (see EXAMPLES). If no error is found for a certificate, <b>verify_callback</b> is called with <b>preverify_ok</b>=1 before advancing to the next level.</p> <p>The return value of <b>verify_callback</b> controls the strategy of the further verification process. If <b>verify_callback</b> returns 0, the verification process is immediately stopped with "verification failed" state. If SSL_VERIFY_PEER is set, a verification failure alert is sent to the peer and the TLS/SSL handshake is terminated. If <b>verify_callback</b> returns 1, the verification process is continued. If <b>verify_callback</b> always returns 1, the TLS/SSL handshake will not be terminated with respect to verification failures and the connection will be established. The calling process can however retrieve the error code of the last verification error using <a href="../man3/SSL_get_verify_result.html">SSL_get_verify_result(3)</a> or by maintaining its own error storage managed by <b>verify_callback</b>.</p> <p>If no <b>verify_callback</b> is specified, the default callback will be used. Its return value is identical to <b>preverify_ok</b>, so that any verification failure will lead to a termination of the TLS/SSL handshake with an alert message, if SSL_VERIFY_PEER is set.</p> <p>After calling SSL_set_post_handshake_auth(), the client will need to add a certificate or certificate callback to its configuration before it can successfully authenticate. This must be called before SSL_connect().</p> <p>SSL_verify_client_post_handshake() requires that verify flags have been previously set, and that a client sent the post-handshake authentication extension. When the client returns a certificate the verify callback will be invoked. A write operation must take place for the Certificate Request to be sent to the client, this can be done with SSL_do_handshake() or SSL_write_ex(). Only one certificate request may be outstanding at any time.</p> <p>When post-handshake authentication occurs, a refreshed NewSessionTicket message is sent to the client.</p> <h1 id="BUGS">BUGS</h1> <p>In client mode, it is not checked whether the SSL_VERIFY_PEER flag is set, but whether any flags other than SSL_VERIFY_NONE are set. This can lead to unexpected behaviour if SSL_VERIFY_PEER and other flags are not used as required.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The SSL*_set_verify*() functions do not provide diagnostic information.</p> <p>The SSL_verify_client_post_handshake() function returns 1 if the request succeeded, and 0 if the request failed.

For convenience, OIDs are usually represented in source code as numeric identifiers, or <i>NID</i>s. OpenSSL has an internal table of OIDs that are generated when the library is built, and their corresponding NIDs are available as defined constants. For the functions below, application code should treat all returned values -- OIDs, NIDs, or names -- as constants.</p> <p>OBJ_nid2obj(), OBJ_nid2ln() and OBJ_nid2sn() convert the NID <i>n</i> to an ASN1_OBJECT structure, its long name and its short name respectively, or <b>NULL</b> if an error occurred.</p> <p>OBJ_obj2nid(), OBJ_ln2nid(), OBJ_sn2nid() return the corresponding NID for the object <i>o</i>, the long name <ln> or the short name <sn> respectively or NID_undef if an error occurred.</p> <p>OBJ_txt2nid() returns NID corresponding to text string <i>s</i>. <i>s</i> can be a long name, a short name or the numerical representation of an object.</p> <p>OBJ_txt2obj() converts the text string <i>s</i> into an ASN1_OBJECT structure. If <i>no_name</i> is 0 then long names and short names will be interpreted as well as numerical forms. If <i>no_name</i> is 1 only the numerical form is acceptable.</p> <p>OBJ_obj2txt() converts the <b>ASN1_OBJECT</b> <i>a</i> into a textual representation. Unless <i>buf</i> is NULL, the representation is written as a NUL-terminated string to <i>buf</i>, where at most <i>buf_len</i> bytes are written, truncating the result if necessary. In any case it returns the total string length, excluding the NUL character, required for non-truncated representation, or -1 on error. If <i>no_name</i> is 0 then if the object has a long or short name then that will be used, otherwise the numerical form will be used. If <i>no_name</i> is 1 then the numerical form will always be used.</p> <p>i2t_ASN1_OBJECT() is the same as OBJ_obj2txt() with the <i>no_name</i> set to zero.</p> <p>OBJ_cmp() compares <i>a</i> to <i>b</i>. If the two are identical 0 is returned.</p> <p>OBJ_dup() returns a copy of <i>o</i>.</p> <p>OBJ_create() adds a new object to the internal table. <i>oid</i> is the numerical form of the object, <i>sn</i> the short name and <i>ln</i> the long name. A new NID is returned for the created object in case of success and NID_undef in case of failure.</p> <p>OBJ_length() returns the size of the content octets of <i>obj</i>.</p> <p>OBJ_get0_data() returns a pointer to the content octets of <i>obj</i>. The returned pointer is an internal pointer which <b>must not</b> be freed.</p> <p>OBJ_cleanup() releases any resources allocated by creating new objects.</p> <h1 id="NOTES">NOTES</h1> <p>Objects in OpenSSL can have a short name, a long name and a numerical identifier (NID) associated with them. A standard set of objects is represented in an internal table. The appropriate values are defined in the header file <b>objects.h</b>.</p> <p>For example the OID for commonName has the following definitions:</p> <pre><code> #define SN_commonName "CN" #define LN_commonName "commonName" #define NID_commonName 13</code></pre> <p>New objects can be added by calling OBJ_create().</p> <p>Table objects have certain advantages over other objects: for example their NIDs can be used in a C language switch statement. They are also static constant structures which are shared: that is there is only a single constant structure for each table object.</p> <p>Objects which are not in the table have the NID value NID_undef.</p> <p>Objects do not need to be in the internal tables to be processed, the functions OBJ_txt2obj() and OBJ_obj2txt() can process the numerical form of an OID.</p> <p>Some objects are used to represent algorithms which do not have a corresponding ASN.1 OBJECT IDENTIFIER encoding (for example no OID currently exists for a particular algorithm).

Integers used for point multiplications will be between 0 and n-1 where n is the <b>order</b>. The <b>order</b> multiplied by the <b>cofactor</b> gives the number of points on the curve.</p> <p>EC_GROUP_get0_generator() returns the generator for the identified <b>group</b>.</p> <p>EC_GROUP_get_order() retrieves the order of <b>group</b> and copies its value into <b>order</b>. It fails in case <b>group</b> is not fully initialized (i.e., its order is not set or set to zero).</p> <p>EC_GROUP_get_cofactor() retrieves the cofactor of <b>group</b> and copies its value into <b>cofactor</b>. It fails in case <b>group</b> is not fully initialized or if the cofactor is not set (or set to zero).</p> <p>The functions EC_GROUP_set_curve_name() and EC_GROUP_get_curve_name(), set and get the NID for the curve respectively (see <a href="../man3/EC_GROUP_new.html">EC_GROUP_new(3)</a>). If a curve does not have a NID associated with it, then EC_GROUP_get_curve_name will return NID_undef.</p> <p>The asn1_flag value is used to determine whether the curve encoding uses explicit parameters or a named curve using an ASN1 OID: many applications only support the latter form. If asn1_flag is <b>OPENSSL_EC_NAMED_CURVE</b> then the named curve form is used and the parameters must have a corresponding named curve NID set. If asn1_flags is <b>OPENSSL_EC_EXPLICIT_CURVE</b> the parameters are explicitly encoded. The functions EC_GROUP_get_asn1_flag() and EC_GROUP_set_asn1_flag() get and set the status of the asn1_flag for the curve. Note: <b>OPENSSL_EC_EXPLICIT_CURVE</b> was added in OpenSSL 1.1.0, for previous versions of OpenSSL the value 0 must be used instead. Before OpenSSL 1.1.0 the default form was to use explicit parameters (meaning that applications would have to explicitly set the named curve form) in OpenSSL 1.1.0 and later the named curve form is the default.</p> <p>The point_conversion_form for a curve controls how EC_POINT data is encoded as ASN1 as defined in X9.62 (ECDSA). point_conversion_form_t is an enum defined as follows:</p> <pre><code> typedef enum { /** the point is encoded as z||x, where the octet z specifies * which solution of the quadratic equation y is */ POINT_CONVERSION_COMPRESSED = 2, /** the point is encoded as z||x||y, where z is the octet 0x04 */ POINT_CONVERSION_UNCOMPRESSED = 4, /** the point is encoded as z||x||y, where the octet z specifies * which solution of the quadratic equation y is */ POINT_CONVERSION_HYBRID = 6 } point_conversion_form_t;</code></pre> <p>For POINT_CONVERSION_UNCOMPRESSED the point is encoded as an octet signifying the UNCOMPRESSED form has been used followed by the octets for x, followed by the octets for y.</p> <p>For any given x co-ordinate for a point on a curve it is possible to derive two possible y values. For POINT_CONVERSION_COMPRESSED the point is encoded as an octet signifying that the COMPRESSED form has been used AND which of the two possible solutions for y has been used, followed by the octets for x.</p> <p>For POINT_CONVERSION_HYBRID the point is encoded as an octet signifying the HYBRID form has been used AND which of the two possible solutions for y has been used, followed by the octets for x, followed by the octets for y.</p> <p>The functions EC_GROUP_set_point_conversion_form() and EC_GROUP_get_point_conversion_form(), set and get the point_conversion_form for the curve respectively.</p> <p>ANSI X9.62 (ECDSA standard) defines a method of generating the curve parameter b from a random number. This provides advantages in that a parameter obtained in this way is highly unlikely to be susceptible to special purpose attacks, or have any trapdoors in it. If the seed is present for a curve then the b parameter was generated in a verifiable fashion using that seed. The OpenSSL EC library does not use this seed value but does enable you to inspect it using EC_GROUP_get0_seed(). This returns a pointer to a memory block containing the seed that was used. The length of the memory block can be obtained using EC_GROUP_get_seed_len(). A number of the built-in curves within the library provide seed values that can be obtained. It is also possible to set a custom seed using EC_GROUP_set_seed() and passing a pointer to a memory block, along with the length of the seed. Again, the EC library will not use this seed value, although it will be preserved in any ASN1 based communications.</p> <p>EC_GROUP_get_degree() gets the degree of the field. For Fp fields this will be the number of bits in p. For F2^m fields this will be the value m.</p> <p>The function EC_GROUP_check_discriminant() calculates the discriminant for the curve and verifies that it is valid. For a curve defined over Fp the discriminant is given by the formula 4*a^3 + 27*b^2 whilst for F2^m curves the discriminant is simply b. In either case for the curve to be valid the discriminant must be non zero.</p> <p>The function EC_GROUP_check() performs a number of checks on a curve to verify that it is valid. Checks performed include verifying that the discriminant is non zero; that a generator has been defined; that the generator is on the curve and has the correct order.</p> <p>EC_GROUP_cmp() compares <b>a</b> and <b>b</b> to determine whether they represent the same curve or not.</p> <p>The functions EC_GROUP_get_basis_type(), EC_GROUP_get_trinomial_basis() and EC_GROUP_get_pentanomial_basis() should only be called for curves defined over an F2^m field. Addition and multiplication operations within an F2^m field are performed using an irreducible polynomial function f(x). This function is either a trinomial of the form:</p> <p>f(x) = x^m + x^k + 1 with m > k >= 1</p> <p>or a pentanomial of the form:</p> <p>f(x) = x^m + x^k3 + x^k2 + x^k1 + 1 with m > k3 > k2 > k1 >= 1</p> <p>The function EC_GROUP_get_basis_type() returns a NID identifying whether a trinomial or pentanomial is in use for the field. The function EC_GROUP_get_trinomial_basis() must only be called where f(x) is of the trinomial form, and returns the value of <b>k</b>. Similarly the function EC_GROUP_get_pentanomial_basis() must only be called where f(x) is of the pentanomial form, and returns the values of <b>k1</b>, <b>k2</b> and <b>k3</b> respectively.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The following functions return 1 on success or 0 on error: EC_GROUP_copy(), EC_GROUP_set_generator(), EC_GROUP_check(), EC_GROUP_check_discriminant(), EC_GROUP_get_trinomial_basis() and EC_GROUP_get_pentanomial_basis().</p> <p>EC_GROUP_dup() returns a pointer to the duplicated curve, or NULL on error.</p> <p>EC_GROUP_method_of() returns the EC_METHOD implementation in use for the given curve or NULL on error.</p> <p>EC_GROUP_get0_generator() returns the generator for the given curve or NULL on error.</p> <p>EC_GROUP_get_order() returns 0 if the order is not set (or set to zero) for <b>group</b> or if copying into <b>order</b> fails, 1 otherwise.</p> <p>EC_GROUP_get_cofactor() returns 0 if the cofactor is not set (or is set to zero) for <b>group</b> or if copying into <b>cofactor</b> fails, 1 otherwise.</p> <p>EC_GROUP_get_curve_name() returns the curve name (NID) for <b>group</b> or will return NID_undef if no curve name is associated.</p> <p>EC_GROUP_get_asn1_flag() returns the ASN1 flag for the specified <b>group</b> .</p> <p>EC_GROUP_get_point_conversion_form() returns the point_conversion_form for <b>group</b>.</p> <p>EC_GROUP_get_degree() returns the degree for <b>group</b> or 0 if the operation is not supported by the underlying group implementation.</p> <p>EC_GROUP_get0_order() returns an internal pointer to the group order.

Early data can be sent by the client immediately after its initial ClientHello without having to wait for the server to complete the handshake. Early data can be sent if a session has previously been established with the server or when establishing a new session using an out-of-band PSK, and only when the server is known to support it. Additionally these functions can be used to send data from the server to the client when the client has not yet completed the authentication stage of the handshake.</p> <p>Early data has weaker security properties than other data sent over an SSL/TLS connection. In particular the data does not have forward secrecy. There are also additional considerations around replay attacks (see <a href="#REPLAY-PROTECTION">"REPLAY PROTECTION"</a> below). For these reasons extreme care should be exercised when using early data. For specific details, consult the TLS 1.3 specification.</p> <p>When a server receives early data it may opt to immediately respond by sending application data back to the client. Data sent by the server at this stage is done before the full handshake has been completed. Specifically the client's authentication messages have not yet been received, i.e. the client is unauthenticated at this point and care should be taken when using this capability.</p> <p>A server or client can determine whether the full handshake has been completed or not by calling <a href="../man3/SSL_is_init_finished.html">SSL_is_init_finished(3)</a>.</p> <p>On the client side, the function SSL_SESSION_get_max_early_data() can be used to determine if a session established with a server can be used to send early data. If the session cannot be used then this function will return 0. Otherwise it will return the maximum number of early data bytes that can be sent.</p> <p>The function SSL_SESSION_set_max_early_data() sets the maximum number of early data bytes that can be sent for a session. This would typically be used when creating a PSK session file (see <a href="../man3/SSL_CTX_set_psk_use_session_callback.html">SSL_CTX_set_psk_use_session_callback(3)</a>). If using a ticket based PSK then this is set automatically to the value provided by the server.</p> <p>A client uses the function SSL_write_early_data() to send early data. This function is similar to the <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a> function, but with the following differences. See <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a> for information on how to write bytes to the underlying connection, and how to handle any errors that may arise. This page describes the differences between SSL_write_early_data() and <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a>.</p> <p>When called by a client, SSL_write_early_data() must be the first IO function called on a new connection, i.e. it must occur before any calls to <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a>, <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a>, <a href="../man3/SSL_connect.html">SSL_connect(3)</a>, <a href="../man3/SSL_do_handshake.html">SSL_do_handshake(3)</a> or other similar functions. It may be called multiple times to stream data to the server, but the total number of bytes written must not exceed the value returned from SSL_SESSION_get_max_early_data(). Once the initial SSL_write_early_data() call has completed successfully the client may interleave calls to <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a> and <a href="../man3/SSL_read.html">SSL_read(3)</a> with calls to SSL_write_early_data() as required.</p> <p>If SSL_write_early_data() fails you should call <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a> to determine the correct course of action, as for <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a>.</p> <p>When the client no longer wishes to send any more early data then it should complete the handshake by calling a function such as <a href="../man3/SSL_connect.html">SSL_connect(3)</a> or <a href="../man3/SSL_do_handshake.html">SSL_do_handshake(3)</a>. Alternatively you can call a standard write function such as <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a>, which will transparently complete the connection and write the requested data.</p> <p>A server may choose to ignore early data that has been sent to it. Once the connection has been completed you can determine whether the server accepted or rejected the early data by calling SSL_get_early_data_status(). This will return SSL_EARLY_DATA_ACCEPTED if the data was accepted, SSL_EARLY_DATA_REJECTED if it was rejected or SSL_EARLY_DATA_NOT_SENT if no early data was sent. This function may be called by either the client or the server.</p> <p>A server uses the SSL_read_early_data() function to receive early data on a connection for which early data has been enabled using SSL_CTX_set_max_early_data() or SSL_set_max_early_data(). As for SSL_write_early_data(), this must be the first IO function called on a connection, i.e. it must occur before any calls to <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a>, <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a>, <a href="../man3/SSL_accept.html">SSL_accept(3)</a>, <a href="../man3/SSL_do_handshake.html">SSL_do_handshake(3)</a>, or other similar functions.</p> <p>SSL_read_early_data() is similar to <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a> with the following differences. Refer to <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a> for full details.</p> <p>SSL_read_early_data() may return 3 possible values:</p> <dl> <dt id="SSL_READ_EARLY_DATA_ERROR">SSL_READ_EARLY_DATA_ERROR</dt> <dd> <p>This indicates an IO or some other error occurred. This should be treated in the same way as a 0 return value from <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a>.</p> </dd> <dt id="SSL_READ_EARLY_DATA_SUCCESS">SSL_READ_EARLY_DATA_SUCCESS</dt> <dd> <p>This indicates that early data was successfully read. This should be treated in the same way as a 1 return value from <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a>. You should continue to call SSL_read_early_data() to read more data.</p> </dd> <dt id="SSL_READ_EARLY_DATA_FINISH">SSL_READ_EARLY_DATA_FINISH</dt> <dd> <p>This indicates that no more early data can be read. It may be returned on the first call to SSL_read_early_data() if the client has not sent any early data, or if the early data was rejected.</p> </dd> </dl> <p>Once the initial SSL_read_early_data() call has completed successfully (i.e. it has returned SSL_READ_EARLY_DATA_SUCCESS or SSL_READ_EARLY_DATA_FINISH) then the server may choose to write data immediately to the unauthenticated client using SSL_write_early_data(). If SSL_read_early_data() returned SSL_READ_EARLY_DATA_FINISH then in some situations (e.g. if the client only supports TLSv1.2) the handshake may have already been completed and calls to SSL_write_early_data() are not allowed. Call <a href="../man3/SSL_is_init_finished.html">SSL_is_init_finished(3)</a> to determine whether the handshake has completed or not. If the handshake is still in progress then the server may interleave calls to SSL_write_early_data() with calls to SSL_read_early_data() as required.</p> <p>Servers must not call <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a>, <a href="../man3/SSL_read.html">SSL_read(3)</a>, <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a> or <a href="../man3/SSL_write.html">SSL_write(3)</a> until SSL_read_early_data() has returned with SSL_READ_EARLY_DATA_FINISH. Once it has done so the connection to the client still needs to be completed. Complete the connection by calling a function such as <a href="../man3/SSL_accept.html">SSL_accept(3)</a> or <a href="../man3/SSL_do_handshake.html">SSL_do_handshake(3)</a>. Alternatively you can call a standard read function such as <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a>, which will transparently complete the connection and read the requested data. Note that it is an error to attempt to complete the connection before SSL_read_early_data() has returned SSL_READ_EARLY_DATA_FINISH.</p> <p>Only servers may call SSL_read_early_data().</p> <p>Calls to SSL_read_early_data() may, in certain circumstances, complete the connection immediately without further need to call a function such as <a href="../man3/SSL_accept.html">SSL_accept(3)</a>. This can happen if the client is using a protocol version less than TLSv1.3. Applications can test for this by calling <a href="../man3/SSL_is_init_finished.html">SSL_is_init_finished(3)</a>. Alternatively, applications may choose to call <a href="../man3/SSL_accept.html">SSL_accept(3)</a> anyway. Such a call will successfully return immediately with no further action taken.</p> <p>When a session is created between a server and a client the server will specify the maximum amount of any early data that it will accept on any future connection attempt. By default the server does not accept early data; a server may indicate support for early data by calling SSL_CTX_set_max_early_data() or SSL_set_max_early_data() to set it for the whole SSL_CTX or an individual SSL object respectively. The <b>max_early_data</b> parameter specifies the maximum amount of early data in bytes that is permitted to be sent on a single connection. Similarly the SSL_CTX_get_max_early_data() and SSL_get_max_early_data() functions can be used to obtain the current maximum early data settings for the SSL_CTX and SSL objects respectively. Generally a server application will either use both of SSL_read_early_data() and SSL_CTX_set_max_early_data() (or SSL_set_max_early_data()), or neither of them, since there is no practical benefit from using only one of them. If the maximum early data setting for a server is nonzero then replay protection is automatically enabled (see <a href="#REPLAY-PROTECTION">"REPLAY PROTECTION"</a> below).</p> <p>If the server rejects the early data sent by a client then it will skip over the data that is sent. The maximum amount of received early data that is skipped is controlled by the recv_max_early_data setting. If a client sends more than this then the connection will abort. This value can be set by calling SSL_CTX_set_recv_max_early_data() or SSL_set_recv_max_early_data(). The current value for this setting can be obtained by calling SSL_CTX_get_recv_max_early_data() or SSL_get_recv_max_early_data(). The default value for this setting is 16,384 bytes.</p> <p>The recv_max_early_data value also has an impact on early data that is accepted. The amount of data that is accepted will always be the lower of the max_early_data for the session and the recv_max_early_data setting for the server. If a client sends more data than this then the connection will abort.</p> <p>The configured value for max_early_data on a server may change over time as required. However, clients may have tickets containing the previously configured max_early_data value. The recv_max_early_data should always be equal to or higher than any recently configured max_early_data value in order to avoid aborted connections. The recv_max_early_data should never be set to less than the current configured max_early_data value.</p> <p>Some server applications may wish to have more control over whether early data is accepted or not, for example to mitigate replay risks (see <a href="#REPLAY-PROTECTION">"REPLAY PROTECTION"</a> below) or to decline early_data when the server is heavily loaded. The functions SSL_CTX_set_allow_early_data_cb() and SSL_set_allow_early_data_cb() set a callback which is called at a point in the handshake immediately before a decision is made to accept or reject early data. The callback is provided with a pointer to the user data argument that was provided when the callback was first set. Returning 1 from the callback will allow early data and returning 0 will reject it. Note that the OpenSSL library may reject early data for other reasons in which case this callback will not get called. Notably, the built-in replay protection feature will still be used even if a callback is present unless it has been explicitly disabled using the SSL_OP_NO_ANTI_REPLAY option. See <a href="#REPLAY-PROTECTION">"REPLAY PROTECTION"</a> below.</p> <h1 id="NOTES">NOTES</h1> <p>The whole purpose of early data is to enable a client to start sending data to the server before a full round trip of network traffic has occurred. Application developers should ensure they consider optimisation of the underlying TCP socket to obtain a performant solution. For example Nagle's algorithm is commonly used by operating systems in an attempt to avoid lots of small TCP packets. In many scenarios this is beneficial for performance, but it does not work well with the early data solution as implemented in OpenSSL. In Nagle's algorithm the OS will buffer outgoing TCP data if a TCP packet has already been sent which we have not yet received an ACK for from the peer. The buffered data will only be transmitted if enough data to fill an entire TCP packet is accumulated, or if the ACK is received from the peer. The initial ClientHello will be sent in the first TCP packet along with any data from the first call to SSL_write_early_data(). If the amount of data written will exceed the size of a single TCP packet, or if there are more calls to SSL_write_early_data() then that additional data will be sent in subsequent TCP packets which will be buffered by the OS and not sent until an ACK is received for the first packet containing the ClientHello. This means the early data is not actually sent until a complete round trip with the server has occurred which defeats the objective of early data.</p> <p>In many operating systems the TCP_NODELAY socket option is available to disable Nagle's algorithm. If an application opts to disable Nagle's algorithm consideration should be given to turning it back on again after the handshake is complete if appropriate.</p> <p>In rare circumstances, it may be possible for a client to have a session that reports a max early data value greater than 0, but where the server does not support this. For example, this can occur if a server has had its configuration changed to accept a lower max early data value such as by calling SSL_CTX_set_recv_max_early_data(). Another example is if a server used to support TLSv1.3 but was later downgraded to TLSv1.2. Sending early data to such a server will cause the connection to abort. Clients that encounter an aborted connection while sending early data may want to retry the connection without sending early data as this does not happen automatically. A client will have to establish a new transport layer connection to the server and attempt the SSL/TLS connection again but without sending early data. Note that it is inadvisable to retry with a lower maximum protocol version.</p> <h1 id="REPLAY-PROTECTION">REPLAY PROTECTION</h1> <p>When early data is in use the TLS protocol provides no security guarantees that the same early data was not replayed across multiple connections. As a mitigation for this issue OpenSSL automatically enables replay protection if the server is configured with a nonzero max early data value. With replay protection enabled sessions are forced to be single use only. If a client attempts to reuse a session ticket more than once, then the second and subsequent attempts will fall back to a full handshake (and any early data that was submitted will be ignored). Note that single use tickets are enforced even if a client does not send any early data.</p> <p>The replay protection mechanism relies on the internal OpenSSL server session cache (see <a href="../man3/SSL_CTX_set_session_cache_mode.html">SSL_CTX_set_session_cache_mode(3)</a>). When replay protection is being used the server will operate as if the SSL_OP_NO_TICKET option had been selected (see <a href="../man3/SSL_CTX_set_options.html">SSL_CTX_set_options(3)</a>). Sessions will be added to the cache whenever a session ticket is issued. When a client attempts to resume the session, OpenSSL will check for its presence in the internal cache. If it exists then the resumption is allowed and the session is removed from the cache. If it does not exist then the resumption is not allowed and a full handshake will occur.</p> <p>Note that some applications may maintain an external cache of sessions (see <a href="../man3/SSL_CTX_sess_set_new_cb.html">SSL_CTX_sess_set_new_cb(3)</a> and similar functions). It is the application's responsibility to ensure that any sessions in the external cache are also populated in the internal cache and that once removed from the internal cache they are similarly removed from the external cache. Failing to do this could result in an application becoming vulnerable to replay attacks. Note that OpenSSL will lock the internal cache while a session is removed but that lock is not held when the remove session callback (see <a href="../man3/SSL_CTX_sess_set_remove_cb.html">SSL_CTX_sess_set_remove_cb(3)</a>) is called. This could result in a small amount of time where the session has been removed from the internal cache but is still available in the external cache. Applications should be designed with this in mind in order to minimise the possibility of replay attacks.</p> <p>The OpenSSL replay protection does not apply to external Pre Shared Keys (PSKs) (e.g. see SSL_CTX_set_psk_find_session_callback(3)). Therefore, extreme caution should be applied when combining external PSKs with early data.</p> <p>Some applications may mitigate the replay risks in other ways. For those applications it is possible to turn off the built-in replay protection feature using the <b>SSL_OP_NO_ANTI_REPLAY</b> option. See <a href="../man3/SSL_CTX_set_options.html">SSL_CTX_set_options(3)</a> for details. Applications can also set a callback to make decisions about accepting early data or not. See SSL_CTX_set_allow_early_data_cb() above for details.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_write_early_data() returns 1 for success or 0 for failure.

The equivalent with BIOs (that is call select() on the underlying I/O structure and then call BIO_read() to read the data) should <b>not</b> be used because a single call to BIO_read() can cause several reads (and writes in the case of SSL BIOs) on the underlying I/O structure and may block as a result.

See the <b>VERIFICATION FLAGS</b> section for a complete description of values the <b>flags</b> parameter can take.</p> <p>X509_VERIFY_PARAM_get_flags() returns the flags in <b>param</b>.</p> <p>X509_VERIFY_PARAM_get_inh_flags() returns the inheritance flags in <b>param</b> which specifies how verification flags are copied from one structure to another. X509_VERIFY_PARAM_set_inh_flags() sets the inheritance flags. See the <b>INHERITANCE FLAGS</b> section for a description of these bits.</p> <p>X509_VERIFY_PARAM_clear_flags() clears the flags <b>flags</b> in <b>param</b>.</p> <p>X509_VERIFY_PARAM_set_purpose() sets the verification purpose in <b>param</b> to <b>purpose</b>. This determines the acceptable purpose of the certificate chain, for example SSL client or SSL server.</p> <p>X509_VERIFY_PARAM_set_trust() sets the trust setting in <b>param</b> to <b>trust</b>.</p> <p>X509_VERIFY_PARAM_set_time() sets the verification time in <b>param</b> to <b>t</b>. Normally the current time is used.</p> <p>X509_VERIFY_PARAM_add0_policy() adds <b>policy</b> to the acceptable policy set. Contrary to preexisting documentation of this function it does not enable policy checking.</p> <p>X509_VERIFY_PARAM_set1_policies() enables policy checking (it is disabled by default) and sets the acceptable policy set to <b>policies</b>. Any existing policy set is cleared. The <b>policies</b> parameter can be <b>NULL</b> to clear an existing policy set.</p> <p>X509_VERIFY_PARAM_set_depth() sets the maximum verification depth to <b>depth</b>. That is the maximum number of intermediate CA certificates that can appear in a chain. A maximal depth chain contains 2 more certificates than the limit, since neither the end-entity certificate nor the trust-anchor count against this limit. Thus a <b>depth</b> limit of 0 only allows the end-entity certificate to be signed directly by the trust-anchor, while with a <b>depth</b> limit of 1 there can be one intermediate CA certificate between the trust-anchor and the end-entity certificate.</p> <p>X509_VERIFY_PARAM_set_auth_level() sets the authentication security level to <b>auth_level</b>. The authentication security level determines the acceptable signature and public key strength when verifying certificate chains. For a certificate chain to validate, the public keys of all the certificates must meet the specified security level. The signature algorithm security level is not enforced for the chain's <i>trust anchor</i> certificate, which is either directly trusted or validated by means other than its signature. See <a href="../man3/SSL_CTX_set_security_level.html">SSL_CTX_set_security_level(3)</a> for the definitions of the available levels. The default security level is -1, or "not set". At security level 0 or lower all algorithms are acceptable. Security level 1 requires at least 80-bit-equivalent security and is broadly interoperable, though it will, for example, reject MD5 signatures or RSA keys shorter than 1024 bits.</p> <p>X509_VERIFY_PARAM_set1_host() sets the expected DNS hostname to <b>name</b> clearing any previously specified hostname or names. If <b>name</b> is NULL, or empty the list of hostnames is cleared, and name checks are not performed on the peer certificate. If <b>name</b> is NUL-terminated, <b>namelen</b> may be zero, otherwise <b>namelen</b> must be set to the length of <b>name</b>.</p> <p>When a hostname is specified, certificate verification automatically invokes <a href="../man3/X509_check_host.html">X509_check_host(3)</a> with flags equal to the <b>flags</b> argument given to X509_VERIFY_PARAM_set_hostflags() (default zero). Applications are strongly advised to use this interface in preference to explicitly calling <a href="../man3/X509_check_host.html">X509_check_host(3)</a>, hostname checks may be out of scope with the DANE-EE(3) certificate usage, and the internal check will be suppressed as appropriate when DANE verification is enabled.</p> <p>When the subject CommonName will not be ignored, whether as a result of the <b>X509_CHECK_FLAG_ALWAYS_CHECK_SUBJECT</b> host flag, or because no DNS subject alternative names are present in the certificate, any DNS name constraints in issuer certificates apply to the subject CommonName as well as the subject alternative name extension.</p> <p>When the subject CommonName will be ignored, whether as a result of the <b>X509_CHECK_FLAG_NEVER_CHECK_SUBJECT</b> host flag, or because some DNS subject alternative names are present in the certificate, DNS name constraints in issuer certificates will not be applied to the subject DN. As described in X509_check_host(3) the <b>X509_CHECK_FLAG_NEVER_CHECK_SUBJECT</b> flag takes precedence over the <b>X509_CHECK_FLAG_ALWAYS_CHECK_SUBJECT</b> flag.</p> <p>X509_VERIFY_PARAM_get_hostflags() returns any host flags previously set via a call to X509_VERIFY_PARAM_set_hostflags().</p> <p>X509_VERIFY_PARAM_add1_host() adds <b>name</b> as an additional reference identifier that can match the peer's certificate. Any previous names set via X509_VERIFY_PARAM_set1_host() or X509_VERIFY_PARAM_add1_host() are retained, no change is made if <b>name</b> is NULL or empty. When multiple names are configured, the peer is considered verified when any name matches.</p> <p>X509_VERIFY_PARAM_get0_peername() returns the DNS hostname or subject CommonName from the peer certificate that matched one of the reference identifiers. When wildcard matching is not disabled, or when a reference identifier specifies a parent domain (starts with ".") rather than a hostname, the peer name may be a wildcard name or a sub-domain of the reference identifier respectively. The return string is allocated by the library and is no longer valid once the associated <b>param</b> argument is freed. Applications must not free the return value.</p> <p>X509_VERIFY_PARAM_set1_email() sets the expected RFC822 email address to <b>email</b>. If <b>email</b> is NUL-terminated, <b>emaillen</b> may be zero, otherwise <b>emaillen</b> must be set to the length of <b>email</b>. When an email address is specified, certificate verification automatically invokes <a href="../man3/X509_check_email.html">X509_check_email(3)</a>.</p> <p>X509_VERIFY_PARAM_set1_ip() sets the expected IP address to <b>ip</b>. The <b>ip</b> argument is in binary format, in network byte-order and <b>iplen</b> must be set to 4 for IPv4 and 16 for IPv6.

An error occurs if a suitable CRL cannot be found.</p> <p><b>X509_V_FLAG_CRL_CHECK_ALL</b> enables CRL checking for the entire certificate chain.</p> <p><b>X509_V_FLAG_IGNORE_CRITICAL</b> disabled critical extension checking. By default any unhandled critical extensions in certificates or (if checked) CRLs results in a fatal error. If this flag is set unhandled critical extensions are ignored. <b>WARNING</b> setting this option for anything other than debugging purposes can be a security risk. Finer control over which extensions are supported can be performed in the verification callback.</p> <p>The <b>X509_V_FLAG_X509_STRICT</b> flag disables workarounds for some broken certificates and makes the verification strictly apply <b>X509</b> rules.</p> <p><b>X509_V_FLAG_ALLOW_PROXY_CERTS</b> enables proxy certificate verification.</p> <p><b>X509_V_FLAG_POLICY_CHECK</b> enables certificate policy checking, by default no policy checking is performed. Additional information is sent to the verification callback relating to policy checking.</p> <p><b>X509_V_FLAG_EXPLICIT_POLICY</b>, <b>X509_V_FLAG_INHIBIT_ANY</b> and <b>X509_V_FLAG_INHIBIT_MAP</b> set the <b>require explicit policy</b>, <b>inhibit any policy</b> and <b>inhibit policy mapping</b> flags respectively as defined in <b>RFC3280</b>. Policy checking is automatically enabled if any of these flags are set.</p> <p>If <b>X509_V_FLAG_NOTIFY_POLICY</b> is set and the policy checking is successful a special status code is set to the verification callback. This permits it to examine the valid policy tree and perform additional checks or simply log it for debugging purposes.</p> <p>By default some additional features such as indirect CRLs and CRLs signed by different keys are disabled. If <b>X509_V_FLAG_EXTENDED_CRL_SUPPORT</b> is set they are enabled.</p> <p>If <b>X509_V_FLAG_USE_DELTAS</b> is set delta CRLs (if present) are used to determine certificate status. If not set deltas are ignored.</p> <p><b>X509_V_FLAG_CHECK_SS_SIGNATURE</b> requests checking the signature of the last certificate in a chain if the certificate is supposedly self-signed. This is prohibited and will result in an error if it is a non-conforming CA certificate with key usage restrictions not including the keyCertSign bit. By default this check is disabled because it doesn't add any additional security but in some cases applications might want to check the signature anyway. A side effect of not checking the self-signature of such a certificate is that disabled or unsupported message digests used for the signature are not treated as fatal errors.</p> <p>When <b>X509_V_FLAG_TRUSTED_FIRST</b> is set, construction of the certificate chain in <a href="../man3/X509_verify_cert.html">X509_verify_cert(3)</a> will search the trust store for issuer certificates before searching the provided untrusted certificates. Local issuer certificates are often more likely to satisfy local security requirements and lead to a locally trusted root. This is especially important when some certificates in the trust store have explicit trust settings (see "TRUST SETTINGS" in <a href="../man1/x509.html">x509(1)</a>). As of OpenSSL 1.1.0 this option is on by default.</p> <p>The <b>X509_V_FLAG_NO_ALT_CHAINS</b> flag suppresses checking for alternative chains. By default, unless <b>X509_V_FLAG_TRUSTED_FIRST</b> is set, when building a certificate chain, if the first certificate chain found is not trusted, then OpenSSL will attempt to replace untrusted certificates supplied by the peer with certificates from the trust store to see if an alternative chain can be found that is trusted. As of OpenSSL 1.1.0, with <b>X509_V_FLAG_TRUSTED_FIRST</b> always set, this option has no effect.</p> <p>The <b>X509_V_FLAG_PARTIAL_CHAIN</b> flag causes intermediate certificates in the trust store to be treated as trust-anchors, in the same way as the self-signed root CA certificates. This makes it possible to trust certificates issued by an intermediate CA without having to trust its ancestor root CA. With OpenSSL 1.1.0 and later and <X509_V_FLAG_PARTIAL_CHAIN> set, chain construction stops as soon as the first certificate from the trust store is added to the chain, whether that certificate is a self-signed "root" certificate or a not self-signed intermediate certificate. Thus, when an intermediate certificate is found in the trust store, the verified chain passed to callbacks may be shorter than it otherwise would be without the <b>X509_V_FLAG_PARTIAL_CHAIN</b> flag.</p> <p>The <b>X509_V_FLAG_NO_CHECK_TIME</b> flag suppresses checking the validity period of certificates and CRLs against the current time. If X509_VERIFY_PARAM_set_time() is used to specify a verification time, the check is not suppressed.</p> <h1 id="INHERITANCE-FLAGS">INHERITANCE FLAGS</h1> <p>These flags specify how parameters are "inherited" from one structure to another.</p> <p>If <b>X509_VP_FLAG_ONCE</b> is set then the current setting is zeroed after the next call.</p> <p>If <b>X509_VP_FLAG_LOCKED</b> is set then no values are copied. This overrides all of the following flags.</p> <p>If <b>X509_VP_FLAG_DEFAULT</b> is set then anything set in the source is copied to the destination. Effectively the values in "to" become default values which will be used only if nothing new is set in "from". This is the default.</p> <p>If <b>X509_VP_FLAG_OVERWRITE</b> is set then all value are copied across whether they are set or not. Flags is still Ored though.</p> <p>If <b>X509_VP_FLAG_RESET_FLAGS</b> is set then the flags value is copied instead of ORed.</p> <h1 id="NOTES">NOTES</h1> <p>The above functions should be used to manipulate verification parameters instead of functions which work in specific structures such as X509_STORE_CTX_set_flags() which are likely to be deprecated in a future release.</p> <h1 id="BUGS">BUGS</h1> <p>Delta CRL checking is currently primitive.

These functions are not normally called directly, various macros are used instead. The standard macros are described below, macros specific to a particular type of BIO are described in the specific BIOs manual page as well as any special features of the standard calls.</p> <p>BIO_reset() typically resets a BIO to some initial state, in the case of file related BIOs for example it rewinds the file pointer to the start of the file.</p> <p>BIO_seek() resets a file related BIO's (that is file descriptor and FILE BIOs) file position pointer to <b>ofs</b> bytes from start of file.</p> <p>BIO_tell() returns the current file position of a file related BIO.</p> <p>BIO_flush() normally writes out any internally buffered data, in some cases it is used to signal EOF and that no more data will be written.</p> <p>BIO_eof() returns 1 if the BIO has read EOF, the precise meaning of "EOF" varies according to the BIO type.</p> <p>BIO_set_close() sets the BIO <b>b</b> close flag to <b>flag</b>. <b>flag</b> can take the value BIO_CLOSE or BIO_NOCLOSE. Typically BIO_CLOSE is used in a source/sink BIO to indicate that the underlying I/O stream should be closed when the BIO is freed.</p> <p>BIO_get_close() returns the BIOs close flag.</p> <p>BIO_pending(), BIO_ctrl_pending(), BIO_wpending() and BIO_ctrl_wpending() return the number of pending characters in the BIOs read and write buffers. Not all BIOs support these calls. BIO_ctrl_pending() and BIO_ctrl_wpending() return a size_t type and are functions, BIO_pending() and BIO_wpending() are macros which call BIO_ctrl().</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>BIO_reset() normally returns 1 for success and 0 or -1 for failure.

The BIO_should_retry() call should be used and appropriate action taken is the call fails.</p> <p>The return values of BIO_pending() and BIO_wpending() may not reliably determine the amount of pending data in all cases. For example in the case of a file BIO some data may be available in the FILE structures internal buffers but it is not possible to determine this in a portably way. For other types of BIO they may not be supported.</p> <p>Filter BIOs if they do not internally handle a particular BIO_ctrl() operation usually pass the operation to the next BIO in the chain. This often means there is no need to locate the required BIO for a particular operation, it can be called on a chain and it will be automatically passed to the relevant BIO. However, this can cause unexpected results: for example no current filter BIOs implement BIO_seek(), but this may still succeed if the chain ends in a FILE or file descriptor BIO.</p> <p>Source/sink BIOs return an 0 if they do not recognize the BIO_ctrl() operation.</p> <h1 id="BUGS">BUGS</h1> <p>Some of the return values are ambiguous and care should be taken.

Do not remove the zero-padding from the decrypted raw RSA data which was computed by RSA_private_decrypt() with <b>RSA_NO_PADDING</b>, as this would create a small timing side channel which could be used to mount a Bleichenbacher attack against any padding mode including PKCS1_OAEP.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/RSA_public_encrypt.html">RSA_public_encrypt(3)</a>, <a href="../man3/RSA_private_decrypt.html">RSA_private_decrypt(3)</a>, <a href="../man3/RSA_sign.html">RSA_sign(3)</a>, <a href="../man3/RSA_verify.html">RSA_verify(3)</a>, <a href="../man7/RAND.html">RAND(7)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2019 The OpenSSL Project Authors.

This is used as the basis for the PSK, and should, at a minimum, have the following fields set:</p> <dl> <dt id="The-master-key">The master key</dt> <dd> <p>This can be set via a call to <a href="../man3/SSL_SESSION_set1_master_key.html">SSL_SESSION_set1_master_key(3)</a>.</p> </dd> <dt id="A-ciphersuite">A ciphersuite</dt> <dd> <p>Only the handshake digest associated with the ciphersuite is relevant for the PSK (the server may go on to negotiate any ciphersuite which is compatible with the digest). The application can use any TLSv1.3 ciphersuite. If <b>md</b> is not NULL the handshake digest for the ciphersuite should be the same. The ciphersuite can be set via a call to <SSL_SESSION_set_cipher(3)>. The handshake digest of an SSL_CIPHER object can be checked using <SSL_CIPHER_get_handshake_digest(3)>.</p> </dd> <dt id="The-protocol-version">The protocol version</dt> <dd> <p>This can be set via a call to <a href="../man3/SSL_SESSION_set_protocol_version.html">SSL_SESSION_set_protocol_version(3)</a> and should be TLS1_3_VERSION.</p> </dd> </dl> <p>Additionally the maximum early data value should be set via a call to <a href="../man3/SSL_SESSION_set_max_early_data.html">SSL_SESSION_set_max_early_data(3)</a> if the PSK will be used for sending early data.</p> <p>Alternatively an SSL_SESSION created from a previous non-PSK handshake may also be used as the basis for a PSK.</p> <p>Ownership of the SSL_SESSION object is passed to the OpenSSL library and so it should not be freed by the application.</p> <p>It is also possible for the callback to succeed but not supply a PSK. In this case no PSK will be sent to the server but the handshake will continue. To do this the callback should return successfully and ensure that <b>*sess</b> is NULL. The contents of <b>*id</b> and <b>*idlen</b> will be ignored.</p> <p>A client application wishing to use PSK ciphersuites for TLSv1.2 and below must provide a different callback function. This function will be called when the client is sending the ClientKeyExchange message to the server.</p> <p>The purpose of the callback function is to select the PSK identity and the pre-shared key to use during the connection setup phase.</p> <p>The callback is set using functions SSL_CTX_set_psk_client_callback() or SSL_set_psk_client_callback(). The callback function is given the connection in parameter <b>ssl</b>, a <b>NULL</b>-terminated PSK identity hint sent by the server in parameter <b>hint</b>, a buffer <b>identity</b> of length <b>max_identity_len</b> bytes where the resulting <b>NUL</b>-terminated identity is to be stored, and a buffer <b>psk</b> of length <b>max_psk_len</b> bytes where the resulting pre-shared key is to be stored.</p> <p>The callback for use in TLSv1.2 will also work in TLSv1.3 although it is recommended to use SSL_CTX_set_psk_use_session_callback() or SSL_set_psk_use_session_callback() for this purpose instead. If TLSv1.3 has been negotiated then OpenSSL will first check to see if a callback has been set via SSL_CTX_set_psk_use_session_callback() or SSL_set_psk_use_session_callback() and it will use that in preference. If no such callback is present then it will check to see if a callback has been set via SSL_CTX_set_psk_client_callback() or SSL_set_psk_client_callback() and use that. In this case the <b>hint</b> value will always be NULL and the handshake digest will default to SHA-256 for any returned PSK. TLSv1.3 early data exchanges are possible in PSK connections only with the <b>SSL_psk_use_session_cb_func</b> callback, and are not possible with the <b>SSL_psk_client_cb_func</b> callback.</p> <h1 id="NOTES">NOTES</h1> <p>Note that parameter <b>hint</b> given to the callback may be <b>NULL</b>.</p> <p>A connection established via a TLSv1.3 PSK will appear as if session resumption has occurred so that <a href="../man3/SSL_session_reused.html">SSL_session_reused(3)</a> will return true.</p> <p>There are no known security issues with sharing the same PSK between TLSv1.2 (or below) and TLSv1.3.

Note that the <b>q</b> parameter is optional. It also contains a public key (<b>pub_key</b>) and (optionally) a private key (<b>priv_key</b>).</p> <p>The <b>p</b>, <b>q</b> and <b>g</b> parameters can be obtained by calling DH_get0_pqg(). If the parameters have not yet been set then <b>*p</b>, <b>*q</b> and <b>*g</b> will be set to NULL. Otherwise they are set to pointers to their respective values. These point directly to the internal representations of the values and therefore should not be freed directly. Any of the out parameters <b>p</b>, <b>q</b>, and <b>g</b> can be NULL, in which case no value will be returned for that parameter.</p> <p>The <b>p</b>, <b>q</b> and <b>g</b> values can be set by calling DH_set0_pqg() and passing the new values for <b>p</b>, <b>q</b> and <b>g</b> as parameters to the function. Calling this function transfers the memory management of the values to the DH object, and therefore the values that have been passed in should not be freed directly after this function has been called. The <b>q</b> parameter may be NULL.</p> <p>To get the public and private key values use the DH_get0_key() function. A pointer to the public key will be stored in <b>*pub_key</b>, and a pointer to the private key will be stored in <b>*priv_key</b>. Either may be NULL if they have not been set yet, although if the private key has been set then the public key must be. The values point to the internal representation of the public key and private key values. This memory should not be freed directly. Any of the out parameters <b>pub_key</b> and <b>priv_key</b> can be NULL, in which case no value will be returned for that parameter.</p> <p>The public and private key values can be set using DH_set0_key(). Either parameter may be NULL, which means the corresponding DH field is left untouched. As with DH_set0_pqg() this function transfers the memory management of the key values to the DH object, and therefore they should not be freed directly after this function has been called.</p> <p>Any of the values <b>p</b>, <b>q</b>, <b>g</b>, <b>priv_key</b>, and <b>pub_key</b> can also be retrieved separately by the corresponding function DH_get0_p(), DH_get0_q(), DH_get0_g(), DH_get0_priv_key(), and DH_get0_pub_key(), respectively.</p> <p>DH_set_flags() sets the flags in the <b>flags</b> parameter on the DH object. Multiple flags can be passed in one go (bitwise ORed together). Any flags that are already set are left set. DH_test_flags() tests to see whether the flags passed in the <b>flags</b> parameter are currently set in the DH object. Multiple flags can be tested in one go. All flags that are currently set are returned, or zero if none of the flags are set. DH_clear_flags() clears the specified flags within the DH object.</p> <p>DH_get0_engine() returns a handle to the ENGINE that has been set for this DH object, or NULL if no such ENGINE has been set.</p> <p>The DH_get_length() and DH_set_length() functions get and set the optional length parameter associated with this DH object. If the length is nonzero then it is used, otherwise it is ignored. The <b>length</b> parameter indicates the length of the secret exponent (private key) in bits.</p> <h1 id="NOTES">NOTES</h1> <p>Values retrieved with DH_get0_key() are owned by the DH object used in the call and may therefore <i>not</i> be passed to DH_set0_key(). If needed, duplicate the received value using BN_dup() and pass the duplicate. The same applies to DH_get0_pqg() and DH_set0_pqg().</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>DH_set0_pqg() and DH_set0_key() return 1 on success or 0 on failure.</p> <p>DH_get0_p(), DH_get0_q(), DH_get0_g(), DH_get0_priv_key(), and DH_get0_pub_key() return the respective value, or NULL if it is unset.</p> <p>DH_test_flags() returns the current state of the flags in the DH object.</p> <p>DH_get0_engine() returns the ENGINE set for the DH object or NULL if no ENGINE has been set.</p> <p>DH_get_length() returns the length of the secret exponent (private key) in bits, or zero if no such length has been explicitly set.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/DH_new.html">DH_new(3)</a>, <a href="../man3/DH_new.html">DH_new(3)</a>, <a href="../man3/DH_generate_parameters.html">DH_generate_parameters(3)</a>, <a href="../man3/DH_generate_key.html">DH_generate_key(3)</a>, <a href="../man3/DH_set_method.html">DH_set_method(3)</a>, <a href="../man3/DH_size.html">DH_size(3)</a>, <a href="../man3/DH_meth_new.html">DH_meth_new(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The functions described here were added in OpenSSL 1.1.0.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2016-2020 The OpenSSL Project Authors.

A new point is constructed by calling the function EC_POINT_new() and providing the <b>group</b> object that the point relates to.</p> <p>EC_POINT_free() frees the memory associated with the <b>EC_POINT</b>. if <b>point</b> is NULL nothing is done.</p> <p>EC_POINT_clear_free() destroys any sensitive data held within the EC_POINT and then frees its memory. If <b>point</b> is NULL nothing is done.</p> <p>EC_POINT_copy() copies the point <b>src</b> into <b>dst</b>. Both <b>src</b> and <b>dst</b> must use the same <b>EC_METHOD</b>.</p> <p>EC_POINT_dup() creates a new <b>EC_POINT</b> object and copies the content from <b>src</b> to the newly created <b>EC_POINT</b> object.</p> <p>EC_POINT_method_of() obtains the <b>EC_METHOD</b> associated with <b>point</b>.</p> <p>A valid point on a curve is the special point at infinity. A point is set to be at infinity by calling EC_POINT_set_to_infinity().</p> <p>The affine co-ordinates for a point describe a point in terms of its x and y position. The function EC_POINT_set_affine_coordinates() sets the <b>x</b> and <b>y</b> co-ordinates for the point <b>p</b> defined over the curve given in <b>group</b>. The function EC_POINT_get_affine_coordinates() sets <b>x</b> and <b>y</b>, either of which may be NULL, to the corresponding coordinates of <b>p</b>.</p> <p>The functions EC_POINT_set_affine_coordinates_GFp() and EC_POINT_set_affine_coordinates_GF2m() are synonyms for EC_POINT_set_affine_coordinates(). They are defined for backwards compatibility only and should not be used.</p> <p>The functions EC_POINT_get_affine_coordinates_GFp() and EC_POINT_get_affine_coordinates_GF2m() are synonyms for EC_POINT_get_affine_coordinates(). They are defined for backwards compatibility only and should not be used.</p> <p>As well as the affine co-ordinates, a point can alternatively be described in terms of its Jacobian projective co-ordinates (for Fp curves only). Jacobian projective co-ordinates are expressed as three values x, y and z. Working in this co-ordinate system provides more efficient point multiplication operations. A mapping exists between Jacobian projective co-ordinates and affine co-ordinates. A Jacobian projective co-ordinate (x, y, z) can be written as an affine co-ordinate as (x/(z^2), y/(z^3)). Conversion to Jacobian projective from affine co-ordinates is simple. The co-ordinate (x, y) is mapped to (x, y, 1). To set or get the projective co-ordinates use EC_POINT_set_Jprojective_coordinates_GFp() and EC_POINT_get_Jprojective_coordinates_GFp() respectively.</p> <p>Points can also be described in terms of their compressed co-ordinates. For a point (x, y), for any given value for x such that the point is on the curve there will only ever be two possible values for y. Therefore, a point can be set using the EC_POINT_set_compressed_coordinates() function where <b>x</b> is the x co-ordinate and <b>y_bit</b> is a value 0 or 1 to identify which of the two possible values for y should be used.</p> <p>The functions EC_POINT_set_compressed_coordinates_GFp() and EC_POINT_set_compressed_coordinates_GF2m() are synonyms for EC_POINT_set_compressed_coordinates(). They are defined for backwards compatibility only and should not be used.</p> <p>In addition <b>EC_POINT</b> can be converted to and from various external representations. The octet form is the binary encoding of the <b>ECPoint</b> structure (as defined in RFC5480 and used in certificates and TLS records): only the content octets are present, the <b>OCTET STRING</b> tag and length are not included. <b>BIGNUM</b> form is the octet form interpreted as a big endian integer converted to a <b>BIGNUM</b> structure. Hexadecimal form is the octet form converted to a NULL terminated character string where each character is one of the printable values 0-9 or A-F (or a-f).</p> <p>The functions EC_POINT_point2oct(), EC_POINT_oct2point(), EC_POINT_point2bn(), EC_POINT_bn2point(), EC_POINT_point2hex() and EC_POINT_hex2point() convert from and to EC_POINTs for the formats: octet, BIGNUM and hexadecimal respectively.</p> <p>The function EC_POINT_point2oct() encodes the given curve point <b>p</b> as an octet string into the buffer <b>buf</b> of size <b>len</b>, using the specified conversion form <b>form</b>. The encoding conforms with Sec. 2.3.3 of the SECG SEC 1 ("Elliptic Curve Cryptography") standard. Similarly the function EC_POINT_oct2point() decodes a curve point into <b>p</b> from the octet string contained in the given buffer <b>buf</b> of size <b>len</b>, conforming to Sec. 2.3.4 of the SECG SEC 1 ("Elliptic Curve Cryptography") standard.</p> <p>The functions EC_POINT_point2hex() and EC_POINT_point2bn() convert a point <b>p</b>, respectively, to the hexadecimal or BIGNUM representation of the same encoding of the function EC_POINT_point2oct(). Vice versa, similarly to the function EC_POINT_oct2point(), the functions EC_POINT_hex2point() and EC_POINT_point2bn() decode the hexadecimal or BIGNUM representation into the EC_POINT <b>p</b>.</p> <p>Notice that, according to the standard, the octet string encoding of the point at infinity for a given curve is fixed to a single octet of value zero and that, vice versa, a single octet of size zero is decoded as the point at infinity.</p> <p>The function EC_POINT_point2oct() must be supplied with a buffer long enough to store the octet form. The return value provides the number of octets stored. Calling the function with a NULL buffer will not perform the conversion but will still return the required buffer length.</p> <p>The function EC_POINT_point2buf() allocates a buffer of suitable length and writes an EC_POINT to it in octet format. The allocated buffer is written to <b>*pbuf</b> and its length is returned. The caller must free up the allocated buffer with a call to OPENSSL_free(). Since the allocated buffer value is written to <b>*pbuf</b> the <b>pbuf</b> parameter <b>MUST NOT</b> be <b>NULL</b>.</p> <p>The function EC_POINT_point2hex() will allocate sufficient memory to store the hexadecimal string. It is the caller's responsibility to free this memory with a subsequent call to OPENSSL_free().</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>EC_POINT_new() and EC_POINT_dup() return the newly allocated EC_POINT or NULL on error.</p> <p>The following functions return 1 on success or 0 on error: EC_POINT_copy(), EC_POINT_set_to_infinity(), EC_POINT_set_Jprojective_coordinates_GFp(), EC_POINT_get_Jprojective_coordinates_GFp(), EC_POINT_set_affine_coordinates_GFp(), EC_POINT_get_affine_coordinates_GFp(), EC_POINT_set_compressed_coordinates_GFp(), EC_POINT_set_affine_coordinates_GF2m(), EC_POINT_get_affine_coordinates_GF2m(), EC_POINT_set_compressed_coordinates_GF2m() and EC_POINT_oct2point().</p> <p>EC_POINT_method_of returns the EC_METHOD associated with the supplied EC_POINT.</p> <p>EC_POINT_point2oct() and EC_POINT_point2buf() return the length of the required buffer or 0 on error.</p> <p>EC_POINT_point2bn() returns the pointer to the BIGNUM supplied, or NULL on error.</p> <p>EC_POINT_bn2point() returns the pointer to the EC_POINT supplied, or NULL on error.</p> <p>EC_POINT_point2hex() returns a pointer to the hex string, or NULL on error.</p> <p>EC_POINT_hex2point() returns the pointer to the EC_POINT supplied, or NULL on error.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/crypto.html">crypto(7)</a>, <a href="../man3/EC_GROUP_new.html">EC_GROUP_new(3)</a>, <a href="../man3/EC_GROUP_copy.html">EC_GROUP_copy(3)</a>, <a href="../man3/EC_POINT_add.html">EC_POINT_add(3)</a>, <a href="../man3/EC_KEY_new.html">EC_KEY_new(3)</a>, <a href="../man3/EC_GFp_simple_method.html">EC_GFp_simple_method(3)</a>, <a href="../man3/d2i_ECPKParameters.html">d2i_ECPKParameters(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2013-2020 The OpenSSL Project Authors.

If a callback function has not been set, the NULL pointer is returned.</p> <h1 id="NOTES">NOTES</h1> <p>In order to allow external session caching, synchronization with the internal session cache is realized via callback functions. Inside these callback functions, session can be saved to disk or put into a database using the <a href="../man3/d2i_SSL_SESSION.html">d2i_SSL_SESSION(3)</a> interface.</p> <p>The new_session_cb() is called whenever a new session has been negotiated and session caching is enabled (see <a href="../man3/SSL_CTX_set_session_cache_mode.html">SSL_CTX_set_session_cache_mode(3)</a>). The new_session_cb() is passed the <b>ssl</b> connection and the nascent ssl session <b>sess</b>. Since sessions are reference-counted objects, the reference count on the session is incremented before the callback, on behalf of the application. If the callback returns <b>0</b>, the session will be immediately removed from the internal cache and the reference count released. If the callback returns <b>1</b>, the application retains the reference (for an entry in the application-maintained "external session cache"), and is responsible for calling SSL_SESSION_free() when the session reference is no longer in use.</p> <p>Note that in TLSv1.3, sessions are established after the main handshake has completed. The server decides when to send the client the session information and this may occur some time after the end of the handshake (or not at all). This means that applications should expect the new_session_cb() function to be invoked during the handshake (for <= TLSv1.2) or after the handshake (for TLSv1.3). It is also possible in TLSv1.3 for multiple sessions to be established with a single connection. In these case the new_session_cb() function will be invoked multiple times.</p> <p>In TLSv1.3 it is recommended that each SSL_SESSION object is only used for resumption once. One way of enforcing that is for applications to call <a href="../man3/SSL_CTX_remove_session.html">SSL_CTX_remove_session(3)</a> after a session has been used.</p> <p>The remove_session_cb() is called whenever the SSL engine removes a session from the internal cache. This can happen when the session is removed because it is expired or when a connection was not shutdown cleanly. It also happens for all sessions in the internal session cache when <a href="../man3/SSL_CTX_free.html">SSL_CTX_free(3)</a> is called. The remove_session_cb() is passed the <b>ctx</b> and the ssl session <b>sess</b>. It does not provide any feedback.</p> <p>The get_session_cb() is only called on SSL/TLS servers, and is given the session id proposed by the client. The get_session_cb() is always called, even when session caching was disabled. The get_session_cb() is passed the <b>ssl</b> connection and the session id of length <b>length</b> at the memory location <b>data</b>. By setting the parameter <b>copy</b> to <b>1</b>, the callback can require the SSL engine to increment the reference count of the SSL_SESSION object; setting <b>copy</b> to <b>0</b> causes the reference count to remain unchanged. If the get_session_cb() does not write to <b>copy</b>, the reference count is incremented and the session must be explicitly freed with <a href="../man3/SSL_SESSION_free.html">SSL_SESSION_free(3)</a>.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CTX_sess_get_new_cb(), SSL_CTX_sess_get_remove_cb() and SSL_CTX_sess_get_get_cb() return different callback function pointers respectively.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ssl.html">ssl(7)</a>, <a href="../man3/d2i_SSL_SESSION.html">d2i_SSL_SESSION(3)</a>, <a href="../man3/SSL_CTX_set_session_cache_mode.html">SSL_CTX_set_session_cache_mode(3)</a>, <a href="../man3/SSL_CTX_flush_sessions.html">SSL_CTX_flush_sessions(3)</a>, <a href="../man3/SSL_SESSION_free.html">SSL_SESSION_free(3)</a>, <a href="../man3/SSL_CTX_free.html">SSL_CTX_free(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2001-2020 The OpenSSL Project Authors.

A BIO pair is a pair of source/sink BIOs where data written to either half of the pair is buffered and can be read from the other half. Both halves must usually by handled by the same application thread since no locking is done on the internal data structures.</p> <p>Since BIO chains typically end in a source/sink BIO it is possible to make this one half of a BIO pair and have all the data processed by the chain under application control.</p> <p>One typical use of BIO pairs is to place TLS/SSL I/O under application control, this can be used when the application wishes to use a non standard transport for TLS/SSL or the normal socket routines are inappropriate.</p> <p>Calls to BIO_read_ex() will read data from the buffer or request a retry if no data is available.</p> <p>Calls to BIO_write_ex() will place data in the buffer or request a retry if the buffer is full.</p> <p>The standard calls BIO_ctrl_pending() and BIO_ctrl_wpending() can be used to determine the amount of pending data in the read or write buffer.</p> <p>BIO_reset() clears any data in the write buffer.</p> <p>BIO_make_bio_pair() joins two separate BIOs into a connected pair.</p> <p>BIO_destroy_pair() destroys the association between two connected BIOs. Freeing up any half of the pair will automatically destroy the association.</p> <p>BIO_shutdown_wr() is used to close down a BIO <b>b</b>. After this call no further writes on BIO <b>b</b> are allowed (they will return an error). Reads on the other half of the pair will return any pending data or EOF when all pending data has been read.</p> <p>BIO_set_write_buf_size() sets the write buffer size of BIO <b>b</b> to <b>size</b>. If the size is not initialized a default value is used. This is currently 17K, sufficient for a maximum size TLS record.</p> <p>BIO_get_write_buf_size() returns the size of the write buffer.</p> <p>BIO_new_bio_pair() combines the calls to BIO_new(), BIO_make_bio_pair() and BIO_set_write_buf_size() to create a connected pair of BIOs <b>bio1</b>, <b>bio2</b> with write buffer sizes <b>writebuf1</b> and <b>writebuf2</b>. If either size is zero then the default size is used. BIO_new_bio_pair() does not check whether <b>bio1</b> or <b>bio2</b> do point to some other BIO, the values are overwritten, BIO_free() is not called.</p> <p>BIO_get_write_guarantee() and BIO_ctrl_get_write_guarantee() return the maximum length of data that can be currently written to the BIO. Writes larger than this value will return a value from BIO_write_ex() less than the amount requested or if the buffer is full request a retry. BIO_ctrl_get_write_guarantee() is a function whereas BIO_get_write_guarantee() is a macro.</p> <p>BIO_get_read_request() and BIO_ctrl_get_read_request() return the amount of data requested, or the buffer size if it is less, if the last read attempt at the other half of the BIO pair failed due to an empty buffer. This can be used to determine how much data should be written to the BIO so the next read will succeed: this is most useful in TLS/SSL applications where the amount of data read is usually meaningful rather than just a buffer size. After a successful read this call will return zero. It also will return zero once new data has been written satisfying the read request or part of it. Note that BIO_get_read_request() never returns an amount larger than that returned by BIO_get_write_guarantee().</p> <p>BIO_ctrl_reset_read_request() can also be used to reset the value returned by BIO_get_read_request() to zero.</p> <h1 id="NOTES">NOTES</h1> <p>Both halves of a BIO pair should be freed. That is even if one half is implicit freed due to a BIO_free_all() or SSL_free() call the other half needs to be freed.</p> <p>When used in bidirectional applications (such as TLS/SSL) care should be taken to flush any data in the write buffer. This can be done by calling BIO_pending() on the other half of the pair and, if any data is pending, reading it and sending it to the underlying transport. This must be done before any normal processing (such as calling select() ) due to a request and BIO_should_read() being true.</p> <p>To see why this is important consider a case where a request is sent using BIO_write_ex() and a response read with BIO_read_ex(), this can occur during an TLS/SSL handshake for example. BIO_write_ex() will succeed and place data in the write buffer. BIO_read_ex() will initially fail and BIO_should_read() will be true. If the application then waits for data to be available on the underlying transport before flushing the write buffer it will never succeed because the request was never sent!</p> <p>BIO_eof() is true if no data is in the peer BIO and the peer BIO has been shutdown.</p> <p>BIO_make_bio_pair(), BIO_destroy_bio_pair(), BIO_shutdown_wr(), BIO_set_write_buf_size(), BIO_get_write_buf_size(), BIO_get_write_guarantee(), and BIO_get_read_request() are implemented as macros.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>BIO_new_bio_pair() returns 1 on success, with the new BIOs available in <b>bio1</b> and <b>bio2</b>, or 0 on failure, with NULL pointers stored into the locations for <b>bio1</b> and <b>bio2</b>. Check the error stack for more information.</p> <p>[XXXXX: More return values need to be added here]</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>The BIO pair can be used to have full control over the network access of an application. The application can call select() on the socket as required without having to go through the SSL-interface.</p> <pre><code> BIO *internal_bio, *network_bio; ... BIO_new_bio_pair(&internal_bio, 0, &network_bio, 0); SSL_set_bio(ssl, internal_bio, internal_bio); SSL_operations(); /* e.g. SSL_read and SSL_write */ ... application | TLS-engine | | +----------> SSL_operations() | /\ || | || \/ | BIO-pair (internal_bio) | BIO-pair (network_bio) | || /\ | \/ || +-----------< BIO_operations() | | | | socket ... SSL_free(ssl); /* implicitly frees internal_bio */ BIO_free(network_bio); ...</code></pre> <p>As the BIO pair will only buffer the data and never directly access the connection, it behaves nonblocking and will return as soon as the write buffer is full or the read buffer is drained. Then the application has to flush the write buffer and/or fill the read buffer.</p> <p>Use the BIO_ctrl_pending(), to find out whether data is buffered in the BIO and must be transferred to the network. Use BIO_ctrl_get_read_request() to find out, how many bytes must be written into the buffer before the SSL_operation() can successfully be continued.</p> <h1 id="WARNINGS">WARNINGS</h1> <p>As the data is buffered, SSL_operation() may return with an ERROR_SSL_WANT_READ condition, but there is still data in the write buffer. An application must not rely on the error value of SSL_operation() but must assure that the write buffer is always flushed first. Otherwise a deadlock may occur as the peer might be waiting for the data before being able to continue.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/SSL_set_bio.html">SSL_set_bio(3)</a>, <a href="../man7/ssl.html">ssl(7)</a>, <a href="../man7/bio.html">bio(7)</a>, <a href="../man3/BIO_should_retry.html">BIO_should_retry(3)</a>, <a href="../man3/BIO_read_ex.html">BIO_read_ex(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2020 The OpenSSL Project Authors.

Calling this function transfers the memory management of the values to the DSA object, and therefore the values that have been passed in should not be freed directly after this function has been called.</p> <p>To get the public and private key values use the DSA_get0_key() function.

In general, manual (re-)seeding of the default OpenSSL random generator (<a href="../man3/RAND_OpenSSL.html">RAND_OpenSSL(3)</a>) is not necessary (but allowed), since it does (re-)seed itself automatically using trusted system entropy sources. This holds unless the default RAND_METHOD has been replaced or OpenSSL was built with automatic reseeding disabled, see <a href="../man7/RAND.html">RAND(7)</a> for more details.</p> <p>RAND_status() indicates whether or not the random generator has been sufficiently seeded. If not, functions such as <a href="../man3/RAND_bytes.html">RAND_bytes(3)</a> will fail.</p> <p>RAND_poll() uses the system's capabilities to seed the random generator using random input obtained from polling various trusted entropy sources. The default choice of the entropy source can be modified at build time, see <a href="../man7/RAND.html">RAND(7)</a> for more details.</p> <p>RAND_add() mixes the <b>num</b> bytes at <b>buf</b> into the internal state of the random generator.

Details about sources of randomness and how to estimate their randomness can be found in the literature; for example [NIST SP 800-90B].

Some seed sources maintain open file descriptors by default, which allows such sources to operate in a chroot(2) jail without the associated device nodes being available. When the <b>keep</b> argument is zero, this call disables the retention of file descriptors. Conversely, a nonzero argument enables the retention of file descriptors.

It performs integrity checks on all the RSA key material, so the RSA key structure must contain all the private key data too. Therefore, it cannot be used with any arbitrary RSA key object, even if it is otherwise fit for regular RSA operation.</p> <p>The <b>cb</b> parameter is a callback that will be invoked in the same manner as <a href="../man3/BN_is_prime_ex.html">BN_is_prime_ex(3)</a>.</p> <p>RSA_check_key() is equivalent to RSA_check_key_ex() with a NULL <b>cb</b>.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>RSA_check_key_ex() and RSA_check_key() return 1 if <b>rsa</b> is a valid RSA key, and 0 otherwise.

An ENGINE implementation can override the way key data is stored and handled, and can even provide support for HSM keys - in which case the RSA structure may contain <b>no</b> key data at all! If the ENGINE in question is only being used for acceleration or analysis purposes, then in all likelihood the RSA key data is complete and untouched, but this can't be assumed in the general case.</p> <h1 id="BUGS">BUGS</h1> <p>A method of verifying the RSA key using opaque RSA API functions might need to be considered. Right now RSA_check_key() simply uses the RSA structure elements directly, bypassing the RSA_METHOD table altogether (and completely violating encapsulation and object-orientation in the process). The best fix will probably be to introduce a "check_key()" handler to the RSA_METHOD function table so that alternative implementations can also provide their own verifiers.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/BN_is_prime_ex.html">BN_is_prime_ex(3)</a>, <a href="../man3/ERR_get_error.html">ERR_get_error(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>RSA_check_key_ex() appeared after OpenSSL 1.0.2.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2018 The OpenSSL Project Authors.

As of OpenSSL 1.0.0, it also checks for newer CRLs upon each lookup, so that newer CRLs are as soon as they appear in the directory.</p> <p>The directory should contain one certificate or CRL per file in PEM format, with a filename of the form <i>hash</i>.<i>N</i> for a certificate, or <i>hash</i>.<b>r</b><i>N</i> for a CRL. The <i>hash</i> is the value returned by the <a href="../man3/X509_NAME_hash.html">X509_NAME_hash(3)</a> function applied to the subject name for certificates or issuer name for CRLs.

Ciphers with DSA keys always use ephemeral DH keys as well. In these cases, the session data are negotiated using the ephemeral/temporary DH key and the key supplied and certified by the certificate chain is only used for signing. Anonymous ciphers (without a permanent server key) also use ephemeral DH keys.</p> <p>Using ephemeral DH key exchange yields forward secrecy, as the connection can only be decrypted, when the DH key is known. By generating a temporary DH key inside the server application that is lost when the application is left, it becomes impossible for an attacker to decrypt past sessions, even if he gets hold of the normal (certified) key, as this key was only used for signing.</p> <p>In order to perform a DH key exchange the server must use a DH group (DH parameters) and generate a DH key. The server will always generate a new DH key during the negotiation.</p> <p>As generating DH parameters is extremely time consuming, an application should not generate the parameters on the fly but supply the parameters. DH parameters can be reused, as the actual key is newly generated during the negotiation. The risk in reusing DH parameters is that an attacker may specialize on a very often used DH group. Applications should therefore generate their own DH parameters during the installation process using the openssl <a href="../man1/dhparam.html">dhparam(1)</a> application. This application guarantees that "strong" primes are used.</p> <p>Files dh2048.pem, and dh4096.pem in the 'apps' directory of the current version of the OpenSSL distribution contain the 'SKIP' DH parameters, which use safe primes and were generated verifiably pseudo-randomly. These files can be converted into C code using the <b>-C</b> option of the <a href="../man1/dhparam.html">dhparam(1)</a> application. Generation of custom DH parameters during installation should still be preferred to stop an attacker from specializing on a commonly used group. File dh1024.pem contains old parameters that must not be used by applications.</p> <p>An application may either directly specify the DH parameters or can supply the DH parameters via a callback function.</p> <p>Previous versions of the callback used <b>is_export</b> and <b>keylength</b> parameters to control parameter generation for export and non-export cipher suites. Modern servers that do not support export cipher suites are advised to either use SSL_CTX_set_tmp_dh() or alternatively, use the callback but ignore <b>keylength</b> and <b>is_export</b> and simply supply at least 2048-bit parameters in the callback.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CTX_set_tmp_dh_callback() and SSL_set_tmp_dh_callback() do not return diagnostic output.</p> <p>SSL_CTX_set_tmp_dh() and SSL_set_tmp_dh() do return 1 on success and 0 on failure.

The hash table entries can be arbitrary structures. Usually they consist of key and value fields. In the description here, <i>TYPE</i> is used a placeholder for any of the OpenSSL datatypes, such as <i>SSL_SESSION</i>.</p> <p>lh_TYPE_new() creates a new <b>LHASH_OF(TYPE)</b> structure to store arbitrary data entries, and specifies the 'hash' and 'compare' callbacks to be used in organising the table's entries. The <b>hash</b> callback takes a pointer to a table entry as its argument and returns an unsigned long hash value for its key field. The hash value is normally truncated to a power of 2, so make sure that your hash function returns well mixed low order bits. The <b>compare</b> callback takes two arguments (pointers to two hash table entries), and returns 0 if their keys are equal, nonzero otherwise.</p> <p>If your hash table will contain items of some particular type and the <b>hash</b> and <b>compare</b> callbacks hash/compare these types, then the <b>IMPLEMENT_LHASH_HASH_FN</b> and <b>IMPLEMENT_LHASH_COMP_FN</b> macros can be used to create callback wrappers of the prototypes required by lh_TYPE_new() as shown in this example:</p> <pre><code> /* * Implement the hash and compare functions; "stuff" can be any word. */ static unsigned long stuff_hash(const TYPE *a) { ... } static int stuff_cmp(const TYPE *a, const TYPE *b) { ... } /* * Implement the wrapper functions. */ static IMPLEMENT_LHASH_HASH_FN(stuff, TYPE) static IMPLEMENT_LHASH_COMP_FN(stuff, TYPE)</code></pre> <p>If the type is going to be used in several places, the following macros can be used in a common header file to declare the function wrappers:</p> <pre><code> DECLARE_LHASH_HASH_FN(stuff, TYPE) DECLARE_LHASH_COMP_FN(stuff, TYPE)</code></pre> <p>Then a hash table of TYPE objects can be created using this:</p> <pre><code> LHASH_OF(TYPE) *htable; htable = lh_TYPE_new(LHASH_HASH_FN(stuff), LHASH_COMP_FN(stuff));</code></pre> <p>lh_TYPE_free() frees the <b>LHASH_OF(TYPE)</b> structure <b>table</b>. Allocated hash table entries will not be freed; consider using lh_TYPE_doall() to deallocate any remaining entries in the hash table (see below).</p> <p>lh_TYPE_insert() inserts the structure pointed to by <b>data</b> into <b>table</b>. If there already is an entry with the same key, the old value is replaced. Note that lh_TYPE_insert() stores pointers, the data are not copied.</p> <p>lh_TYPE_delete() deletes an entry from <b>table</b>.</p> <p>lh_TYPE_retrieve() looks up an entry in <b>table</b>. Normally, <b>data</b> is a structure with the key field(s) set; the function will return a pointer to a fully populated structure.</p> <p>lh_TYPE_doall() will, for every entry in the hash table, call <b>func</b> with the data item as its parameter. For example:</p> <pre><code> /* Cleans up resources belonging to 'a' (this is implemented elsewhere) */ void TYPE_cleanup_doall(TYPE *a); /* Implement a prototype-compatible wrapper for "TYPE_cleanup" */ IMPLEMENT_LHASH_DOALL_FN(TYPE_cleanup, TYPE) /* Call "TYPE_cleanup" against all items in a hash table. */ lh_TYPE_doall(hashtable, LHASH_DOALL_FN(TYPE_cleanup)); /* Then the hash table itself can be deallocated */ lh_TYPE_free(hashtable);</code></pre> <p>When doing this, be careful if you delete entries from the hash table in your callbacks: the table may decrease in size, moving the item that you are currently on down lower in the hash table - this could cause some entries to be skipped during the iteration. The second best solution to this problem is to set hash->down_load=0 before you start (which will stop the hash table ever decreasing in size). The best solution is probably to avoid deleting items from the hash table inside a "doall" callback!</p> <p>lh_TYPE_doall_arg() is the same as lh_TYPE_doall() except that <b>func</b> will be called with <b>arg</b> as the second argument and <b>func</b> should be of type <b>LHASH_DOALL_ARG_FN_TYPE</b> (a callback prototype that is passed both the table entry and an extra argument). As with lh_doall(), you can instead choose to declare your callback with a prototype matching the types you are dealing with and use the declare/implement macros to create compatible wrappers that cast variables before calling your type-specific callbacks. An example of this is demonstrated here (printing all hash table entries to a BIO that is provided by the caller):</p> <pre><code> /* Prints item 'a' to 'output_bio' (this is implemented elsewhere) */ void TYPE_print_doall_arg(const TYPE *a, BIO *output_bio); /* Implement a prototype-compatible wrapper for "TYPE_print" */ static IMPLEMENT_LHASH_DOALL_ARG_FN(TYPE, const TYPE, BIO) /* Print out the entire hashtable to a particular BIO */ lh_TYPE_doall_arg(hashtable, LHASH_DOALL_ARG_FN(TYPE_print), BIO, logging_bio);</code></pre> <p>lh_TYPE_error() can be used to determine if an error occurred in the last operation.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>lh_TYPE_new() returns <b>NULL</b> on error, otherwise a pointer to the new <b>LHASH</b> structure.</p> <p>When a hash table entry is replaced, lh_TYPE_insert() returns the value being replaced. <b>NULL</b> is returned on normal operation and on error.</p> <p>lh_TYPE_delete() returns the entry being deleted. <b>NULL</b> is returned if there is no such value in the hash table.</p> <p>lh_TYPE_retrieve() returns the hash table entry if it has been found, <b>NULL</b> otherwise.</p> <p>lh_TYPE_error() returns 1 if an error occurred in the last operation, 0 otherwise. It's meaningful only after non-retrieve operations.</p> <p>lh_TYPE_free(), lh_TYPE_doall() and lh_TYPE_doall_arg() return no values.</p> <h1 id="NOTE">NOTE</h1> <p>The LHASH code is not thread safe. All updating operations, as well as lh_TYPE_error call must be performed under a write lock. All retrieve operations should be performed under a read lock, <i>unless</i> accurate usage statistics are desired. In which case, a write lock should be used for retrieve operations as well. For output of the usage statistics, using the functions from <a href="../man3/OPENSSL_LH_stats.html">OPENSSL_LH_stats(3)</a>, a read lock suffices.</p> <p>The LHASH code regards table entries as constant data. As such, it internally represents lh_insert()'d items with a "const void *" pointer type. This is why callbacks such as those used by lh_doall() and lh_doall_arg() declare their prototypes with "const", even for the parameters that pass back the table items' data pointers - for consistency, user-provided data is "const" at all times as far as the LHASH code is concerned. However, as callers are themselves providing these pointers, they can choose whether they too should be treating all such parameters as constant.</p> <p>As an example, a hash table may be maintained by code that, for reasons of encapsulation, has only "const" access to the data being indexed in the hash table (i.e. it is returned as "const" from elsewhere in their code) - in this case the LHASH prototypes are appropriate as-is. Conversely, if the caller is responsible for the life-time of the data in question, then they may well wish to make modifications to table item passed back in the lh_doall() or lh_doall_arg() callbacks (see the "TYPE_cleanup" example above). If so, the caller can either cast the "const" away (if they're providing the raw callbacks themselves) or use the macros to declare/implement the wrapper functions without "const" types.</p> <p>Callers that only have "const" access to data they're indexing in a table, yet declare callbacks without constant types (or cast the "const" away themselves), are therefore creating their own risks/bugs without being encouraged to do so by the API. On a related note, those auditing code should pay special attention to any instances of DECLARE/IMPLEMENT_LHASH_DOALL_[ARG_]_FN macros that provide types without any "const" qualifiers.</p> <h1 id="BUGS">BUGS</h1> <p>lh_TYPE_insert() returns <b>NULL</b> both for success and error.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/OPENSSL_LH_stats.html">OPENSSL_LH_stats(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>In OpenSSL 1.0.0, the lhash interface was revamped for better type checking.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2022 The OpenSSL Project Authors.

On success SSL_read_ex() will store the number of bytes actually read in <b>*readbytes</b>.</p> <p>SSL_peek_ex() and SSL_peek() are identical to SSL_read_ex() and SSL_read() respectively except no bytes are actually removed from the underlying BIO during the read, so that a subsequent call to SSL_read_ex() or SSL_read() will yield at least the same bytes.</p> <h1 id="NOTES">NOTES</h1> <p>In the paragraphs below a "read function" is defined as one of SSL_read_ex(), SSL_read(), SSL_peek_ex() or SSL_peek().</p> <p>If necessary, a read function will negotiate a TLS/SSL session, if not already explicitly performed by <a href="../man3/SSL_connect.html">SSL_connect(3)</a> or <a href="../man3/SSL_accept.html">SSL_accept(3)</a>. If the peer requests a re-negotiation, it will be performed transparently during the read function operation. The behaviour of the read functions depends on the underlying BIO.</p> <p>For the transparent negotiation to succeed, the <b>ssl</b> must have been initialized to client or server mode. This is being done by calling <a href="../man3/SSL_set_connect_state.html">SSL_set_connect_state(3)</a> or SSL_set_accept_state() before the first invocation of a read function.</p> <p>The read functions work based on the SSL/TLS records. The data are received in records (with a maximum record size of 16kB). Only when a record has been completely received, can it be processed (decryption and check of integrity). Therefore, data that was not retrieved at the last read call can still be buffered inside the SSL layer and will be retrieved on the next read call. If <b>num</b> is higher than the number of bytes buffered then the read functions will return with the bytes buffered. If no more bytes are in the buffer, the read functions will trigger the processing of the next record. Only when the record has been received and processed completely will the read functions return reporting success. At most the contents of one record will be returned. As the size of an SSL/TLS record may exceed the maximum packet size of the underlying transport (e.g. TCP), it may be necessary to read several packets from the transport layer before the record is complete and the read call can succeed.</p> <p>If <b>SSL_MODE_AUTO_RETRY</b> has been switched off and a non-application data record has been processed, the read function can return and set the error to <b>SSL_ERROR_WANT_READ</b>. In this case there might still be unprocessed data available in the <b>BIO</b>. If read ahead was set using <a href="../man3/SSL_CTX_set_read_ahead.html">SSL_CTX_set_read_ahead(3)</a>, there might also still be unprocessed data available in the <b>SSL</b>. This behaviour can be controlled using the <a href="../man3/SSL_CTX_set_mode.html">SSL_CTX_set_mode(3)</a> call.</p> <p>If the underlying BIO is <b>blocking</b>, a read function will only return once the read operation has been finished or an error occurred, except when a non-application data record has been processed and <b>SSL_MODE_AUTO_RETRY</b> is not set. Note that if <b>SSL_MODE_AUTO_RETRY</b> is set and only non-application data is available the call will hang.</p> <p>If the underlying BIO is <b>nonblocking</b>, a read function will also return when the underlying BIO could not satisfy the needs of the function to continue the operation. In this case a call to <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a> with the return value of the read function will yield <b>SSL_ERROR_WANT_READ</b> or <b>SSL_ERROR_WANT_WRITE</b>. As at any time it's possible that non-application data needs to be sent, a read function can also cause write operations. The calling process then must repeat the call after taking appropriate action to satisfy the needs of the read function. The action depends on the underlying BIO. When using a nonblocking socket, nothing is to be done, but select() can be used to check for the required condition. When using a buffering BIO, like a BIO pair, data must be written into or retrieved out of the BIO before being able to continue.</p> <p><a href="../man3/SSL_pending.html">SSL_pending(3)</a> can be used to find out whether there are buffered bytes available for immediate retrieval. In this case the read function can be called without blocking or actually receiving new data from the underlying socket.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_read_ex() and SSL_peek_ex() will return 1 for success or 0 for failure. Success means that 1 or more application data bytes have been read from the SSL connection. Failure means that no bytes could be read from the SSL connection. Failures can be retryable (e.g. we are waiting for more bytes to be delivered by the network) or non-retryable (e.g. a fatal network error). In the event of a failure call <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a> to find out the reason which indicates whether the call is retryable or not.</p> <p>For SSL_read() and SSL_peek() the following return values can occur:</p> <dl> <dt id="pod0">> 0</dt> <dd> <p>The read operation was successful. The return value is the number of bytes actually read from the TLS/SSL connection.</p> </dd> <dt id="pod-0"><= 0</dt> <dd> <p>The read operation was not successful, because either the connection was closed, an error occurred or action must be taken by the calling process.

The argument supplied when setting the callback is passed back to the callback at runtime. A callback that returns failure (0) will cause the connection to terminate, and callbacks returning failure should indicate what alert value is to be sent in the <b>al</b> parameter. A callback may also return a negative value to suspend the handshake, and the handshake function will return immediately. <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a> will return SSL_ERROR_WANT_CLIENT_HELLO_CB to indicate that the handshake was suspended. It is the job of the ClientHello callback to store information about the state of the last call if needed to continue. On the next call into the handshake function, the ClientHello callback will be called again, and, if it returns success, normal handshake processing will continue from that point.</p> <p>SSL_client_hello_isv2() indicates whether the ClientHello was carried in a SSLv2 record and is in the SSLv2 format. The SSLv2 format has substantial differences from the normal SSLv3 format, including using three bytes per cipher suite, and not allowing extensions. Additionally, the SSLv2 format 'challenge' field is exposed via SSL_client_hello_get0_random(), padded to SSL3_RANDOM_SIZE bytes with zeros if needed. For SSLv2 format ClientHellos, SSL_client_hello_get0_compression_methods() returns a dummy list that only includes the null compression method, since the SSLv2 format does not include a mechanism by which to negotiate compression.</p> <p>SSL_client_hello_get0_random(), SSL_client_hello_get0_session_id(), SSL_client_hello_get0_ciphers(), and SSL_client_hello_get0_compression_methods() provide access to the corresponding ClientHello fields, returning the field length and optionally setting an out pointer to the octets of that field.</p> <p>Similarly, SSL_client_hello_get0_ext() provides access to individual extensions from the ClientHello on a per-extension basis. For the provided wire protocol extension type value, the extension value and length are returned in the output parameters (if present).</p> <p>SSL_client_hello_get1_extensions_present() can be used prior to SSL_client_hello_get0_ext(), to determine which extensions are present in the ClientHello before querying for them. The <b>out</b> and <b>outlen</b> parameters are both required, and on success the caller must release the storage allocated for <b>*out</b> using OPENSSL_free(). The contents of <b>*out</b> is an array of integers holding the numerical value of the TLS extension types in the order they appear in the ClientHello. <b>*outlen</b> contains the number of elements in the array. In situations when the ClientHello has no extensions, the function will return success with <b>*out</b> set to NULL and <b>*outlen</b> set to 0.</p> <h1 id="NOTES">NOTES</h1> <p>The ClientHello callback provides a vast window of possibilities for application code to affect the TLS handshake. A primary use of the callback is to allow the server to examine the server name indication extension provided by the client in order to select an appropriate certificate to present, and make other configuration adjustments relevant to that server name and its configuration. Such configuration changes can include swapping out the associated SSL_CTX pointer, modifying the server's list of permitted TLS versions, changing the server's cipher list in response to the client's cipher list, etc.</p> <p>It is also recommended that applications utilize a ClientHello callback and not use a servername callback, in order to avoid unexpected behavior that occurs due to the relative order of processing between things like session resumption and the historical servername callback.</p> <p>The SSL_client_hello_* family of functions may only be called from code executing within a ClientHello callback.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The application's supplied ClientHello callback returns SSL_CLIENT_HELLO_SUCCESS on success, SSL_CLIENT_HELLO_ERROR on failure, and SSL_CLIENT_HELLO_RETRY to suspend processing.</p> <p>SSL_client_hello_isv2() returns 1 for SSLv2-format ClientHellos and 0 otherwise.</p> <p>SSL_client_hello_get0_random(), SSL_client_hello_get0_session_id(), SSL_client_hello_get0_ciphers(), and SSL_client_hello_get0_compression_methods() return the length of the corresponding ClientHello fields. If zero is returned, the output pointer should not be assumed to be valid.</p> <p>SSL_client_hello_get0_ext() returns 1 if the extension of type 'type' is present, and 0 otherwise.</p> <p>SSL_client_hello_get1_extensions_present() returns 1 on success and 0 on failure.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ssl.html">ssl(7)</a>, <a href="../man3/SSL_CTX_set_tlsext_servername_callback.html">SSL_CTX_set_tlsext_servername_callback(3)</a>, <a>SSL_bytes_to_cipher_list</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The SSL ClientHello callback, SSL_client_hello_isv2(), SSL_client_hello_get0_random(), SSL_client_hello_get0_session_id(), SSL_client_hello_get0_ciphers(), SSL_client_hello_get0_compression_methods(), SSL_client_hello_get0_ext(), and SSL_client_hello_get1_extensions_present() were added in OpenSSL 1.1.1.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2017-2019 The OpenSSL Project Authors.

Data written to a memory BIO is stored in a BUF_MEM structure which is extended as appropriate to accommodate the stored data.</p> <p>BIO_s_secmem() is like BIO_s_mem() except that the secure heap is used for buffer storage.</p> <p>Any data written to a memory BIO can be recalled by reading from it. Unless the memory BIO is read only any data read from it is deleted from the BIO.</p> <p>Memory BIOs support BIO_gets() and BIO_puts().</p> <p>If the BIO_CLOSE flag is set when a memory BIO is freed then the underlying BUF_MEM structure is also freed.</p> <p>Calling BIO_reset() on a read write memory BIO clears any data in it if the flag BIO_FLAGS_NONCLEAR_RST is not set, otherwise it just restores the read pointer to the state it was just after the last write was performed and the data can be read again. On a read only BIO it similarly restores the BIO to its original state and the read only data can be read again.</p> <p>BIO_eof() is true if no data is in the BIO.</p> <p>BIO_ctrl_pending() returns the number of bytes currently stored.</p> <p>BIO_set_mem_eof_return() sets the behaviour of memory BIO <b>b</b> when it is empty. If the <b>v</b> is zero then an empty memory BIO will return EOF (that is it will return zero and BIO_should_retry(b) will be false. If <b>v</b> is non zero then it will return <b>v</b> when it is empty and it will set the read retry flag (that is BIO_read_retry(b) is true). To avoid ambiguity with a normal positive return value <b>v</b> should be set to a negative value, typically -1.</p> <p>BIO_get_mem_data() sets *<b>pp</b> to a pointer to the start of the memory BIOs data and returns the total amount of data available. It is implemented as a macro.</p> <p>BIO_set_mem_buf() sets the internal BUF_MEM structure to <b>bm</b> and sets the close flag to <b>c</b>, that is <b>c</b> should be either BIO_CLOSE or BIO_NOCLOSE. It is a macro.</p> <p>BIO_get_mem_ptr() places the underlying BUF_MEM structure in *<b>pp</b>. It is a macro.</p> <p>BIO_new_mem_buf() creates a memory BIO using <b>len</b> bytes of data at <b>buf</b>, if <b>len</b> is -1 then the <b>buf</b> is assumed to be nul terminated and its length is determined by <b>strlen</b>. The BIO is set to a read only state and as a result cannot be written to. This is useful when some data needs to be made available from a static area of memory in the form of a BIO. The supplied data is read directly from the supplied buffer: it is <b>not</b> copied first, so the supplied area of memory must be unchanged until the BIO is freed.</p> <h1 id="NOTES">NOTES</h1> <p>Writes to memory BIOs will always succeed if memory is available: that is their size can grow indefinitely.</p> <p>Every write after partial read (not all data in the memory buffer was read) to a read write memory BIO will have to move the unread data with an internal copy operation, if a BIO contains a lot of data and it is read in small chunks intertwined with writes the operation can be very slow. Adding a buffering BIO to the chain can speed up the process.</p> <p>Calling BIO_set_mem_buf() on a BIO created with BIO_new_secmem() will give undefined results, including perhaps a program crash.</p> <p>Switching the memory BIO from read write to read only is not supported and can give undefined results including a program crash. There are two notable exceptions to the rule. The first one is to assign a static memory buffer immediately after BIO creation and set the BIO as read only.</p> <p>The other supported sequence is to start with read write BIO then temporarily switch it to read only and call BIO_reset() on the read only BIO immediately before switching it back to read write. Before the BIO is freed it must be switched back to the read write mode.</p> <p>Calling BIO_get_mem_ptr() on read only BIO will return a BUF_MEM that contains only the remaining data to be read. If the close status of the BIO is set to BIO_NOCLOSE, before freeing the BUF_MEM the data pointer in it must be set to NULL as the data pointer does not point to an allocated memory.</p> <p>Calling BIO_reset() on a read write memory BIO with BIO_FLAGS_NONCLEAR_RST flag set can have unexpected outcome when the reads and writes to the BIO are intertwined. As documented above the BIO will be reset to the state after the last completed write operation. The effects of reads preceding that write operation cannot be undone.</p> <p>Calling BIO_get_mem_ptr() prior to a BIO_reset() call with BIO_FLAGS_NONCLEAR_RST set has the same effect as a write operation.</p> <h1 id="BUGS">BUGS</h1> <p>There should be an option to set the maximum size of a memory BIO.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>BIO_s_mem() and BIO_s_secmem() return a valid memory <b>BIO_METHOD</b> structure.</p> <p>BIO_set_mem_eof_return(), BIO_set_mem_buf() and BIO_get_mem_ptr() return 1 on success or a value which is less than or equal to 0 if an error occurred.</p> <p>BIO_get_mem_data() returns the total number of bytes available on success, 0 if b is NULL, or a negative value in case of other errors.</p> <p>BIO_new_mem_buf() returns a valid <b>BIO</b> structure on success or NULL on error.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Create a memory BIO and write some data to it:</p> <pre><code> BIO *mem = BIO_new(BIO_s_mem()); BIO_puts(mem, "Hello World\n");</code></pre> <p>Create a read only memory BIO:</p> <pre><code> char data[] = "Hello World"; BIO *mem = BIO_new_mem_buf(data, -1);</code></pre> <p>Extract the BUF_MEM structure from a memory BIO and then free up the BIO:</p> <pre><code> BUF_MEM *bptr; BIO_get_mem_ptr(mem, &bptr); BIO_set_close(mem, BIO_NOCLOSE); /* So BIO_free() leaves BUF_MEM alone */ BIO_free(mem);</code></pre> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2019 The OpenSSL Project Authors.

This function simply wraps calls to EC_KEY_new() and EC_GROUP_new_by_curve_name().</p> <p>Calling EC_KEY_free() decrements the reference count for the EC_KEY object, and if it has dropped to zero then frees the memory associated with it.

The callback functions are implemented and provided by the caller. Their parameter lists need to match the function prototypes above.</p> <p>Setting the callbacks is allowed only if the DRBG has not been initialized yet. Otherwise, the operation will fail. To change the settings for one of the three shared DRBGs it is necessary to call RAND_DRBG_uninstantiate() first.</p> <p>The <b>get_entropy</b>() callback is called by the <b>drbg</b> when it requests fresh random input. It is expected that the callback allocates and fills a random buffer of size <b>min_len</b> <= size <= <b>max_len</b> (in bytes) which contains at least <b>entropy</b> bits of randomness. The <b>prediction_resistance</b> flag indicates whether the reseeding was triggered by a prediction resistance request.</p> <p>The buffer's address is to be returned in *<b>pout</b> and the number of collected randomness bytes as return value.</p> <p>If the callback fails to acquire at least <b>entropy</b> bits of randomness, it must indicate an error by returning a buffer length of 0.</p> <p>If <b>prediction_resistance</b> was requested and the random source of the DRBG does not satisfy the conditions requested by [NIST SP 800-90C], then it must also indicate an error by returning a buffer length of 0. See NOTES section for more details.</p> <p>The <b>cleanup_entropy</b>() callback is called from the <b>drbg</b> to clear and free the buffer allocated previously by get_entropy(). The values <b>out</b> and <b>outlen</b> are the random buffer's address and length, as returned by the get_entropy() callback.</p> <p>The <b>get_nonce</b>() and <b>cleanup_nonce</b>() callbacks are used to obtain a nonce and free it again. A nonce is only required for instantiation (not for reseeding) and only in the case where the DRBG uses a derivation function. The callbacks are analogous to get_entropy() and cleanup_entropy(), except for the missing prediction_resistance flag.</p> <p>If the derivation function is disabled, then no nonce is used for instantiation, and the <b>get_nonce</b>() and <b>cleanup_nonce</b>() callbacks can be omitted by setting them to NULL.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>RAND_DRBG_set_callbacks() return 1 on success, and 0 on failure</p> <h1 id="NOTES">NOTES</h1> <p>It is important that <b>cleanup_entropy</b>() and <b>cleanup_nonce</b>() clear the buffer contents safely before freeing it, in order not to leave sensitive information about the DRBG's state in memory.</p> <p>A request for prediction resistance can only be satisfied by pulling fresh entropy from one of the approved entropy sources listed in section 5.5.2 of [NIST SP 800-90C]. Since the default implementation of the get_entropy callback does not have access to such an approved entropy source, a request for prediction resistance will always fail. In other words, prediction resistance is currently not supported yet by the DRBG.</p> <p>The derivation function is disabled during initialization by calling the RAND_DRBG_set() function with the RAND_DRBG_FLAG_CTR_NO_DF flag. For more information on the derivation function and when it can be omitted, see [NIST SP 800-90A Rev. 1]. Roughly speaking it can be omitted if the random source has "full entropy", i.e., contains 8 bits of entropy per byte.</p> <p>Even if a nonce is required, the <b>get_nonce</b>() and <b>cleanup_nonce</b>() callbacks can be omitted by setting them to NULL. In this case the DRBG will automatically request an extra amount of entropy (using the <b>get_entropy</b>() and <b>cleanup_entropy</b>() callbacks) which it will utilize for the nonce, following the recommendations of [NIST SP 800-90A Rev. 1], section 8.6.7.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/RAND_DRBG_new.html">RAND_DRBG_new(3)</a>, <a href="../man3/RAND_DRBG_reseed.html">RAND_DRBG_reseed(3)</a>, <a href="../man7/RAND_DRBG.html">RAND_DRBG(7)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The RAND_DRBG functions were added in OpenSSL 1.1.1.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2017-2020 The OpenSSL Project Authors.

These functions are:</p> <dl> <dt id="an-opener">an opener</dt> <dd> <p>This function takes a reference to a UI and starts a session, for example by opening a channel to a tty, or by creating a dialog box.</p> </dd> <dt id="a-writer">a writer</dt> <dd> <p>This function takes a reference to a UI and a UI String, and writes the string where appropriate, maybe to the tty, maybe added as a field label in a dialog box. Note that this gets fed all strings associated with a UI, one after the other, so care must be taken which ones it actually uses.</p> </dd> <dt id="a-flusher">a flusher</dt> <dd> <p>This function takes a reference to a UI, and flushes everything that has been output so far. For example, if the method builds up a dialog box, this can be used to actually display it and accepting input ended with a pressed button.</p> </dd> <dt id="a-reader">a reader</dt> <dd> <p>This function takes a reference to a UI and a UI string and reads off the given prompt, maybe from the tty, maybe from a field in a dialog box. Note that this gets fed all strings associated with a UI, one after the other, so care must be taken which ones it actually uses.</p> </dd> <dt id="a-closer">a closer</dt> <dd> <p>This function takes a reference to a UI, and closes the session, maybe by closing the channel to the tty, maybe by destroying a dialog box.</p> </dd> </dl> <p>All of these functions are expected to return 0 on error, 1 on success, or -1 on out-off-band events, for example if some prompting has been cancelled (by pressing Ctrl-C, for example). Only the flusher or the reader are expected to return -1. If returned by another of the functions, it's treated as if 0 was returned.</p> <p>Regarding the writer and the reader, don't assume the former should only write and don't assume the latter should only read. This depends on the needs of the method.</p> <p>For example, a typical tty reader wouldn't write the prompts in the write, but would rather do so in the reader, because of the sequential nature of prompting on a tty. This is how the UI_OpenSSL() method does it.</p> <p>In contrast, a method that builds up a dialog box would add all prompt text in the writer, have all input read in the flusher and store the results in some temporary buffer, and finally have the reader just fetch those results.</p> <p>The central function that uses these method functions is UI_process(), and it does it in five steps:</p> <ol> <li><p>Open the session using the opener function if that one's defined. If an error occurs, jump to 5.</p> </li> <li><p>For every UI String associated with the UI, call the writer function if that one's defined. If an error occurs, jump to 5.</p> </li> <li><p>Flush everything using the flusher function if that one's defined. If an error occurs, jump to 5.</p> </li> <li><p>For every UI String associated with the UI, call the reader function if that one's defined. If an error occurs, jump to 5.</p> </li> <li><p>Close the session using the closer function if that one's defined.</p> </li> </ol> <p>UI_create_method() creates a new UI method with a given <b>name</b>.</p> <p>UI_destroy_method() destroys the given UI method <b>ui_method</b>.</p> <p>UI_method_set_opener(), UI_method_set_writer(), UI_method_set_flusher(), UI_method_set_reader() and UI_method_set_closer() set the five main method function to the given function pointer.</p> <p>UI_method_set_data_duplicator() sets the user data duplicator and destructor.

These macros define typesafe inline functions that wrap around the utility <b>OPENSSL_sk_</b> API. In the description here, <i>TYPE</i> is used as a placeholder for any of the OpenSSL datatypes, such as <i>X509</i>.</p> <p>STACK_OF() returns the name for a stack of the specified <b>TYPE</b>. DEFINE_STACK_OF() creates set of functions for a stack of <b>TYPE</b>. This will mean that type <b>TYPE</b> is stored in each stack, the type is referenced by STACK_OF(TYPE) and each function name begins with <i>sk_TYPE_</i>. For example:</p> <pre><code> TYPE *sk_TYPE_value(STACK_OF(TYPE) *sk, int idx);</code></pre> <p>DEFINE_STACK_OF_CONST() is identical to DEFINE_STACK_OF() except each element is constant. For example:</p> <pre><code> const TYPE *sk_TYPE_value(STACK_OF(TYPE) *sk, int idx);</code></pre> <p>DEFINE_SPECIAL_STACK_OF() defines a stack of <b>TYPE</b> but each function uses <b>FUNCNAME</b> in the function name. For example:</p> <pre><code> TYPE *sk_FUNCNAME_value(STACK_OF(TYPE) *sk, int idx);</code></pre> <p>DEFINE_SPECIAL_STACK_OF_CONST() is similar except that each element is constant:</p> <pre><code> const TYPE *sk_FUNCNAME_value(STACK_OF(TYPE) *sk, int idx);</code></pre> <p>sk_TYPE_num() returns the number of elements in <b>sk</b> or -1 if <b>sk</b> is <b>NULL</b>.</p> <p>sk_TYPE_value() returns element <b>idx</b> in <b>sk</b>, where <b>idx</b> starts at zero. If <b>idx</b> is out of range then <b>NULL</b> is returned.</p> <p>sk_TYPE_new() allocates a new empty stack using comparison function <b>compare</b>. If <b>compare</b> is <b>NULL</b> then no comparison function is used. This function is equivalent to sk_TYPE_new_reserve(compare, 0).</p> <p>sk_TYPE_new_null() allocates a new empty stack with no comparison function. This function is equivalent to sk_TYPE_new_reserve(NULL, 0).</p> <p>sk_TYPE_reserve() allocates additional memory in the <b>sk</b> structure such that the next <b>n</b> calls to sk_TYPE_insert(), sk_TYPE_push() or sk_TYPE_unshift() will not fail or cause memory to be allocated or reallocated. If <b>n</b> is zero, any excess space allocated in the <b>sk</b> structure is freed. On error <b>sk</b> is unchanged.</p> <p>sk_TYPE_new_reserve() allocates a new stack. The new stack will have additional memory allocated to hold <b>n</b> elements if <b>n</b> is positive. The next <b>n</b> calls to sk_TYPE_insert(), sk_TYPE_push() or sk_TYPE_unshift() will not fail or cause memory to be allocated or reallocated. If <b>n</b> is zero or less than zero, no memory is allocated. sk_TYPE_new_reserve() also sets the comparison function <b>compare</b> to the newly created stack. If <b>compare</b> is <b>NULL</b> then no comparison function is used.</p> <p>sk_TYPE_set_cmp_func() sets the comparison function of <b>sk</b> to <b>compare</b>. The previous comparison function is returned or <b>NULL</b> if there was no previous comparison function.</p> <p>sk_TYPE_free() frees up the <b>sk</b> structure. It does <b>not</b> free up any elements of <b>sk</b>. After this call <b>sk</b> is no longer valid.</p> <p>sk_TYPE_zero() sets the number of elements in <b>sk</b> to zero. It does not free <b>sk</b> so after this call <b>sk</b> is still valid.</p> <p>sk_TYPE_pop_free() frees up all elements of <b>sk</b> and <b>sk</b> itself. The free function freefunc() is called on each element to free it.</p> <p>sk_TYPE_delete() deletes element <b>i</b> from <b>sk</b>. It returns the deleted element or <b>NULL</b> if <b>i</b> is out of range.</p> <p>sk_TYPE_delete_ptr() deletes element matching <b>ptr</b> from <b>sk</b>. It returns the deleted element or <b>NULL</b> if no element matching <b>ptr</b> was found.</p> <p>sk_TYPE_insert() inserts <b>ptr</b> into <b>sk</b> at position <b>idx</b>. Any existing elements at or after <b>idx</b> are moved downwards. If <b>idx</b> is out of range the new element is appended to <b>sk</b>. sk_TYPE_insert() either returns the number of elements in <b>sk</b> after the new element is inserted or zero if an error (such as memory allocation failure) occurred.</p> <p>sk_TYPE_push() appends <b>ptr</b> to <b>sk</b> it is equivalent to:</p> <pre><code> sk_TYPE_insert(sk, ptr, -1);</code></pre> <p>sk_TYPE_unshift() inserts <b>ptr</b> at the start of <b>sk</b> it is equivalent to:</p> <pre><code> sk_TYPE_insert(sk, ptr, 0);</code></pre> <p>sk_TYPE_pop() returns and removes the last element from <b>sk</b>.</p> <p>sk_TYPE_shift() returns and removes the first element from <b>sk</b>.</p> <p>sk_TYPE_set() sets element <b>idx</b> of <b>sk</b> to <b>ptr</b> replacing the current element. The new element value is returned or <b>NULL</b> if an error occurred: this will only happen if <b>sk</b> is <b>NULL</b> or <b>idx</b> is out of range.</p> <p>sk_TYPE_find() searches <b>sk</b> for the element <b>ptr</b>. In the case where no comparison function has been specified, the function performs a linear search for a pointer equal to <b>ptr</b>. The index of the first matching element is returned or <b>-1</b> if there is no match. In the case where a comparison function has been specified, <b>sk</b> is sorted then sk_TYPE_find() returns the index of a matching element or <b>-1</b> if there is no match. Note that, in this case, the matching element returned is not guaranteed to be the first; the comparison function will usually compare the values pointed to rather than the pointers themselves and the order of elements in <b>sk</b> could change.</p> <p>sk_TYPE_find_ex() operates like sk_TYPE_find() except when a comparison function has been specified and no matching element is found. Instead of returning <b>-1</b>, sk_TYPE_find_ex() returns the index of the element either before or after the location where <b>ptr</b> would be if it were present in <b>sk</b>.</p> <p>sk_TYPE_sort() sorts <b>sk</b> using the supplied comparison function.</p> <p>sk_TYPE_is_sorted() returns <b>1</b> if <b>sk</b> is sorted and <b>0</b> otherwise.</p> <p>sk_TYPE_dup() returns a copy of <b>sk</b>. Note the pointers in the copy are identical to the original.</p> <p>sk_TYPE_deep_copy() returns a new stack where each element has been copied. Copying is performed by the supplied copyfunc() and freeing by freefunc(). The function freefunc() is only called if an error occurs.</p> <h1 id="NOTES">NOTES</h1> <p>Care should be taken when accessing stacks in multi-threaded environments. Any operation which increases the size of a stack such as sk_TYPE_insert() or sk_push() can "grow" the size of an internal array and cause race conditions if the same stack is accessed in a different thread. Operations such as sk_find() and sk_sort() can also reorder the stack.</p> <p>Any comparison function supplied should use a metric suitable for use in a binary search operation. That is it should return zero, a positive or negative value if <b>a</b> is equal to, greater than or less than <b>b</b> respectively.</p> <p>Care should be taken when checking the return values of the functions sk_TYPE_find() and sk_TYPE_find_ex(). They return an index to the matching element. In particular <b>0</b> indicates a matching first element. A failed search is indicated by a <b>-1</b> return value.</p> <p>STACK_OF(), DEFINE_STACK_OF(), DEFINE_STACK_OF_CONST(), and DEFINE_SPECIAL_STACK_OF() are implemented as macros.</p> <p>The underlying utility <b>OPENSSL_sk_</b> API should not be used directly.

The content is a series of base64-encoded lines, surrounded by begin/end markers each on their own line. For example:</p> <pre><code> -----BEGIN PRIVATE KEY----- MIICdg.... ... bhTQ== -----END PRIVATE KEY-----</code></pre> <p>Optional header line(s) may appear after the begin line, and their existence depends on the type of object being written or read.</p> <p>PEM_write() writes to the file <b>fp</b>, while PEM_write_bio() writes to the BIO <b>bp</b>. The <b>name</b> is the name to use in the marker, the <b>header</b> is the header value or NULL, and <b>data</b> and <b>len</b> specify the data and its length.</p> <p>The final <b>data</b> buffer is typically an ASN.1 object which can be decoded with the <b>d2i</b> function appropriate to the type <b>name</b>; see <a href="../man3/d2i_X509.html">d2i_X509(3)</a> for examples.</p> <p>PEM_read() reads from the file <b>fp</b>, while PEM_read_bio() reads from the BIO <b>bp</b>. Both skip any non-PEM data that precedes the start of the next PEM object. When an object is successfully retrieved, the type name from the "----BEGIN <type>-----" is returned via the <b>name</b> argument, any encapsulation headers are returned in <b>header</b> and the base64-decoded content and its length are returned via <b>data</b> and <b>len</b> respectively. The <b>name</b>, <b>header</b> and <b>data</b> pointers are allocated via OPENSSL_malloc() and should be freed by the caller via OPENSSL_free() when no longer needed.</p> <p>PEM_get_EVP_CIPHER_INFO() can be used to determine the <b>data</b> returned by PEM_read() or PEM_read_bio() is encrypted and to retrieve the associated cipher and IV. The caller passes a pointer to structure of type <b>EVP_CIPHER_INFO</b> via the <b>cinfo</b> argument and the <b>header</b> returned via PEM_read() or PEM_read_bio(). If the call is successful 1 is returned and the cipher and IV are stored at the address pointed to by <b>cinfo</b>. When the header is malformed, or not supported or when the cipher is unknown or some internal error happens 0 is returned. This function is deprecated, see <b>NOTES</b> below.</p> <p>PEM_do_header() can then be used to decrypt the data if the header indicates encryption. The <b>cinfo</b> argument is a pointer to the structure initialized by the previous call to PEM_get_EVP_CIPHER_INFO(). The <b>data</b> and <b>len</b> arguments are those returned by the previous call to PEM_read() or PEM_read_bio(). The <b>cb</b> and <b>u</b> arguments make it possible to override the default password prompt function as described in <a href="../man3/PEM_read_PrivateKey.html">PEM_read_PrivateKey(3)</a>. On successful completion the <b>data</b> is decrypted in place, and <b>len</b> is updated to indicate the plaintext length. This function is deprecated, see <b>NOTES</b> below.</p> <p>If the data is a priori known to not be encrypted, then neither PEM_do_header() nor PEM_get_EVP_CIPHER_INFO() need be called.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>PEM_read() and PEM_read_bio() return 1 on success and 0 on failure, the latter includes the case when no more PEM objects remain in the input file. To distinguish end of file from more serious errors the caller must peek at the error stack and check for <b>PEM_R_NO_START_LINE</b>, which indicates that no more PEM objects were found. See <a href="../man3/ERR_peek_last_error.html">ERR_peek_last_error(3)</a>, <a href="../man3/ERR_GET_REASON.html">ERR_GET_REASON(3)</a>.</p> <p>PEM_get_EVP_CIPHER_INFO() and PEM_do_header() return 1 on success, and 0 on failure. The <b>data</b> is likely meaningless if these functions fail.</p> <h1 id="NOTES">NOTES</h1> <p>The PEM_get_EVP_CIPHER_INFO() and PEM_do_header() functions are deprecated. This is because the underlying PEM encryption format is obsolete, and should be avoided. It uses an encryption format with an OpenSSL-specific key-derivation function, which employs MD5 with an iteration count of 1!

If the <b>updatetype</b> parameter is set to <b>SSL_KEY_UPDATE_REQUESTED</b> then the sending keys for this connection will be updated and the peer will be informed of the change along with a request for the peer to additionally update its sending keys. It is an error if <b>updatetype</b> is set to <b>SSL_KEY_UPDATE_NONE</b>.</p> <p>SSL_key_update() must only be called after the initial handshake has been completed and TLSv1.3 has been negotiated. The key update will not take place until the next time an IO operation such as SSL_read_ex() or SSL_write_ex() takes place on the connection. Alternatively SSL_do_handshake() can be called to force the update to take place immediately.</p> <p>SSL_get_key_update_type() can be used to determine whether a key update operation has been scheduled but not yet performed. The type of the pending key update operation will be returned if there is one, or SSL_KEY_UPDATE_NONE otherwise.</p> <p>SSL_renegotiate() and SSL_renegotiate_abbreviated() should only be called for connections that have negotiated TLSv1.2 or less. Calling them on any other connection will result in an error.</p> <p>When called from the client side, SSL_renegotiate() schedules a completely new handshake over an existing SSL/TLS connection. The next time an IO operation such as SSL_read_ex() or SSL_write_ex() takes place on the connection a check will be performed to confirm that it is a suitable time to start a renegotiation. If so, then it will be initiated immediately. OpenSSL will not attempt to resume any session associated with the connection in the new handshake.</p> <p>When called from the client side, SSL_renegotiate_abbreviated() works in the same was as SSL_renegotiate() except that OpenSSL will attempt to resume the session associated with the current connection in the new handshake.</p> <p>When called from the server side, SSL_renegotiate() and SSL_renegotiate_abbreviated() behave identically. They both schedule a request for a new handshake to be sent to the client. The next time an IO operation is performed then the same checks as on the client side are performed and then, if appropriate, the request is sent. The client may or may not respond with a new handshake and it may or may not attempt to resume an existing session. If a new handshake is started then this will be handled transparently by calling any OpenSSL IO function.</p> <p>If an OpenSSL client receives a renegotiation request from a server then again this will be handled transparently through calling any OpenSSL IO function. For a TLS connection the client will attempt to resume the current session in the new handshake. For historical reasons, DTLS clients will not attempt to resume the session in the new handshake.</p> <p>The SSL_renegotiate_pending() function returns 1 if a renegotiation or renegotiation request has been scheduled but not yet acted on, or 0 otherwise.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_key_update(), SSL_renegotiate() and SSL_renegotiate_abbreviated() return 1 on success or 0 on error.</p> <p>SSL_get_key_update_type() returns the update type of the pending key update operation or SSL_KEY_UPDATE_NONE if there is none.</p> <p>SSL_renegotiate_pending() returns 1 if a renegotiation or renegotiation request has been scheduled but not yet acted on, or 0 otherwise.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ssl.html">ssl(7)</a>, <a href="../man3/SSL_read_ex.html">SSL_read_ex(3)</a>, <a href="../man3/SSL_write_ex.html">SSL_write_ex(3)</a>, <a href="../man3/SSL_do_handshake.html">SSL_do_handshake(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The SSL_key_update() and SSL_get_key_update_type() functions were added in OpenSSL 1.1.1.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2017-2019 The OpenSSL Project Authors.

SSL_use_certificate_file() loads the certificate from <b>file</b> into <b>ssl</b>. See the NOTES section on why SSL_CTX_use_certificate_chain_file() should be preferred.</p> <p>SSL_CTX_use_certificate_chain_file() loads a certificate chain from <b>file</b> into <b>ctx</b>. The certificates must be in PEM format and must be sorted starting with the subject's certificate (actual client or server certificate), followed by intermediate CA certificates if applicable, and ending at the highest level (root) CA. SSL_use_certificate_chain_file() is similar except it loads the certificate chain into <b>ssl</b>.</p> <p>SSL_CTX_use_PrivateKey() adds <b>pkey</b> as private key to <b>ctx</b>. SSL_CTX_use_RSAPrivateKey() adds the private key <b>rsa</b> of type RSA to <b>ctx</b>. SSL_use_PrivateKey() adds <b>pkey</b> as private key to <b>ssl</b>; SSL_use_RSAPrivateKey() adds <b>rsa</b> as private key of type RSA to <b>ssl</b>. If a certificate has already been set and the private does not belong to the certificate an error is returned. To change a certificate, private key pair the new certificate needs to be set with SSL_use_certificate() or SSL_CTX_use_certificate() before setting the private key with SSL_CTX_use_PrivateKey() or SSL_use_PrivateKey().</p> <p>SSL_CTX_use_cert_and_key() and SSL_use_cert_and_key() assign the X.509 certificate <b>x</b>, private key <b>key</b>, and certificate <b>chain</b> onto the corresponding <b>ssl</b> or <b>ctx</b>. The <b>pkey</b> argument must be the private key of the X.509 certificate <b>x</b>. If the <b>override</b> argument is 0, then <b>x</b>, <b>pkey</b> and <b>chain</b> are set only if all were not previously set. If <b>override</b> is non-0, then the certificate, private key and chain certs are always set. If <b>pkey</b> is NULL, then the public key of <b>x</b> is used as the private key. This is intended to be used with hardware (via the ENGINE interface) that stores the private key securely, such that it cannot be accessed by OpenSSL. The reference count of the public key is incremented (twice if there is no private key); it is not copied nor duplicated. This allows all private key validations checks to succeed without an actual private key being assigned via SSL_CTX_use_PrivateKey(), etc.</p> <p>SSL_CTX_use_PrivateKey_ASN1() adds the private key of type <b>pk</b> stored at memory location <b>d</b> (length <b>len</b>) to <b>ctx</b>.

The formatting <b>type</b> of the private key must be specified from the known types SSL_FILETYPE_PEM, SSL_FILETYPE_ASN1. SSL_CTX_use_RSAPrivateKey_file() adds the first private RSA key found in <b>file</b> to <b>ctx</b>. SSL_use_PrivateKey_file() adds the first private key found in <b>file</b> to <b>ssl</b>; SSL_use_RSAPrivateKey_file() adds the first private RSA key found to <b>ssl</b>.</p> <p>SSL_CTX_check_private_key() checks the consistency of a private key with the corresponding certificate loaded into <b>ctx</b>. If more than one key/certificate pair (RSA/DSA) is installed, the last item installed will be checked. If e.g. the last item was a RSA certificate or key, the RSA key/certificate pair will be checked. SSL_check_private_key() performs the same check for <b>ssl</b>. If no key/certificate was explicitly added for this <b>ssl</b>, the last item added into <b>ctx</b> will be checked.</p> <h1 id="NOTES">NOTES</h1> <p>The internal certificate store of OpenSSL can hold several private key/certificate pairs at a time. The certificate used depends on the cipher selected, see also <a href="../man3/SSL_CTX_set_cipher_list.html">SSL_CTX_set_cipher_list(3)</a>.</p> <p>When reading certificates and private keys from file, files of type SSL_FILETYPE_ASN1 (also known as <b>DER</b>, binary encoding) can only contain one certificate or private key, consequently SSL_CTX_use_certificate_chain_file() is only applicable to PEM formatting. Files of type SSL_FILETYPE_PEM can contain more than one item.</p> <p>SSL_CTX_use_certificate_chain_file() adds the first certificate found in the file to the certificate store. The other certificates are added to the store of chain certificates using <a href="../man3/SSL_CTX_add1_chain_cert.html">SSL_CTX_add1_chain_cert(3)</a>. Note: versions of OpenSSL before 1.0.2 only had a single certificate chain store for all certificate types, OpenSSL 1.0.2 and later have a separate chain store for each type. SSL_CTX_use_certificate_chain_file() should be used instead of the SSL_CTX_use_certificate_file() function in order to allow the use of complete certificate chains even when no trusted CA storage is used or when the CA issuing the certificate shall not be added to the trusted CA storage.</p> <p>If additional certificates are needed to complete the chain during the TLS negotiation, CA certificates are additionally looked up in the locations of trusted CA certificates, see <a href="../man3/SSL_CTX_load_verify_locations.html">SSL_CTX_load_verify_locations(3)</a>.</p> <p>The private keys loaded from file can be encrypted. In order to successfully load encrypted keys, a function returning the passphrase must have been supplied, see <a href="../man3/SSL_CTX_set_default_passwd_cb.html">SSL_CTX_set_default_passwd_cb(3)</a>. (Certificate files might be encrypted as well from the technical point of view, it however does not make sense as the data in the certificate is considered public anyway.)</p> <p>All of the functions to set a new certificate will replace any existing certificate of the same type that has already been set. Similarly all of the functions to set a new private key will replace any private key that has already been set. Applications should call <a href="../man3/SSL_CTX_check_private_key.html">SSL_CTX_check_private_key(3)</a> or <a href="../man3/SSL_check_private_key.html">SSL_check_private_key(3)</a> as appropriate after loading a new certificate and private key to confirm that the certificate and key match.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>On success, the functions return 1.

This is because the code then becomes transparent to the algorithm used and much more flexible.</p> <p>EVP_DigestSign() is a one shot operation which signs a single block of data in one function. For algorithms that support streaming it is equivalent to calling EVP_DigestSignUpdate() and EVP_DigestSignFinal(). For algorithms which do not support streaming (e.g. PureEdDSA) it is the only way to sign data.</p> <p>In previous versions of OpenSSL there was a link between message digest types and public key algorithms. This meant that "clone" digests such as EVP_dss1() needed to be used to sign using SHA1 and DSA. This is no longer necessary and the use of clone digest is now discouraged.</p> <p>For some key types and parameters the random number generator must be seeded. If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to external circumstances (see <a href="../man7/RAND.html">RAND(7)</a>), the operation will fail.</p> <p>The call to EVP_DigestSignFinal() internally finalizes a copy of the digest context. This means that calls to EVP_DigestSignUpdate() and EVP_DigestSignFinal() can be called later to digest and sign additional data.</p> <p>Since only a copy of the digest context is ever finalized, the context must be cleaned up after use by calling EVP_MD_CTX_free() or a memory leak will occur.</p> <p>The use of EVP_PKEY_size() with these functions is discouraged because some signature operations may have a signature length which depends on the parameters set. As a result EVP_PKEY_size() would have to return a value which indicates the maximum possible signature for any set of parameters.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/EVP_DigestVerifyInit.html">EVP_DigestVerifyInit(3)</a>, <a href="../man3/EVP_DigestInit.html">EVP_DigestInit(3)</a>, <a href="../man7/evp.html">evp(7)</a>, <a href="../man3/HMAC.html">HMAC(3)</a>, <a href="../man3/MD2.html">MD2(3)</a>, <a href="../man3/MD5.html">MD5(3)</a>, <a href="../man3/MDC2.html">MDC2(3)</a>, <a href="../man3/RIPEMD160.html">RIPEMD160(3)</a>, <a href="../man3/SHA1.html">SHA1(3)</a>, <a href="../man1/dgst.html">dgst(1)</a>, <a href="../man7/RAND.html">RAND(7)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>EVP_DigestSignInit(), EVP_DigestSignUpdate() and EVP_DigestSignFinal() were added in OpenSSL 1.0.0.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2006-2020 The OpenSSL Project Authors.

This capability could be utilised to parallelise the processing of a single connection. For example a single write can be split into multiple records and each one encrypted independently and in parallel. Note: this will only work in TLS1.1+. There is no support in SSLv3, TLSv1.0 or DTLS (any version). This capability is known as "pipelining" within OpenSSL.</p> <p>In order to benefit from the pipelining capability. You need to have an engine that provides ciphers that support this. The OpenSSL "dasync" engine provides AES128-SHA based ciphers that have this capability. However, these are for development and test purposes only.</p> <p>SSL_CTX_set_max_send_fragment() and SSL_set_max_send_fragment() set the <b>max_send_fragment</b> parameter for SSL_CTX and SSL objects respectively. This value restricts the amount of plaintext bytes that will be sent in any one SSL/TLS record. By default its value is SSL3_RT_MAX_PLAIN_LENGTH (16384). These functions will only accept a value in the range 512 - SSL3_RT_MAX_PLAIN_LENGTH.</p> <p>SSL_CTX_set_max_pipelines() and SSL_set_max_pipelines() set the maximum number of pipelines that will be used at any one time. This value applies to both "read" pipelining and "write" pipelining. By default only one pipeline will be used (i.e. normal non-parallel operation). The number of pipelines set must be in the range 1 - SSL_MAX_PIPELINES (32). Setting this to a value > 1 will also automatically turn on "read_ahead" (see <a href="../man3/SSL_CTX_set_read_ahead.html">SSL_CTX_set_read_ahead(3)</a>). This is explained further below. OpenSSL will only every use more than one pipeline if a cipher suite is negotiated that uses a pipeline capable cipher provided by an engine.</p> <p>Pipelining operates slightly differently for reading encrypted data compared to writing encrypted data. SSL_CTX_set_split_send_fragment() and SSL_set_split_send_fragment() define how data is split up into pipelines when writing encrypted data. The number of pipelines used will be determined by the amount of data provided to the SSL_write_ex() or SSL_write() call divided by <b>split_send_fragment</b>.</p> <p>For example if <b>split_send_fragment</b> is set to 2000 and <b>max_pipelines</b> is 4 then:</p> <p>SSL_write/SSL_write_ex called with 0-2000 bytes == 1 pipeline used</p> <p>SSL_write/SSL_write_ex called with 2001-4000 bytes == 2 pipelines used</p> <p>SSL_write/SSL_write_ex called with 4001-6000 bytes == 3 pipelines used</p> <p>SSL_write/SSL_write_ex called with 6001+ bytes == 4 pipelines used</p> <p><b>split_send_fragment</b> must always be less than or equal to <b>max_send_fragment</b>. By default it is set to be equal to <b>max_send_fragment</b>. This will mean that the same number of records will always be created as would have been created in the non-parallel case, although the data will be apportioned differently. In the parallel case data will be spread equally between the pipelines.</p> <p>Read pipelining is controlled in a slightly different way than with write pipelining. While reading we are constrained by the number of records that the peer (and the network) can provide to us in one go. The more records we can get in one go the more opportunity we have to parallelise the processing. As noted above when setting <b>max_pipelines</b> to a value greater than one, <b>read_ahead</b> is automatically set. The <b>read_ahead</b> parameter causes OpenSSL to attempt to read as much data into the read buffer as the network can provide and will fit into the buffer. Without this set data is read into the read buffer one record at a time. The more data that can be read, the more opportunity there is for parallelising the processing at the cost of increased memory overhead per connection. Setting <b>read_ahead</b> can impact the behaviour of the SSL_pending() function (see <a href="../man3/SSL_pending.html">SSL_pending(3)</a>).</p> <p>The SSL_CTX_set_default_read_buffer_len() and SSL_set_default_read_buffer_len() functions control the size of the read buffer that will be used. The <b>len</b> parameter sets the size of the buffer. The value will only be used if it is greater than the default that would have been used anyway.

So any list of CA names set is never sent from client to server and the list of CA names retrieved by SSL_get0_peer_CA_list() is always <b>NULL</b>.</p> <p>For TLS 1.3 the list of CA names is sent using the <b>certificate_authorities</b> extension and may be sent by a client (in the ClientHello message) or by a server (when requesting a certificate).</p> <p>In most cases it is not necessary to set CA names on the client side. The list of CA names that are acceptable to the client will be sent in plaintext to the server. This has privacy implications and may also have performance implications if the list is large. This optional capability was introduced as part of TLSv1.3 and therefore setting CA names on the client side will have no impact if that protocol version has been disabled. Most servers do not need this and so this should be avoided unless required.</p> <p>The "client CA list" functions below only have an effect when called on the server side.</p> <p>SSL_CTX_set_client_CA_list() sets the <b>list</b> of CAs sent to the client when requesting a client certificate for <b>ctx</b>.

In client mode, SSL_get_client_CA_list returns the list of client CAs sent from the server, if any. The returned list should not be freed by the caller.</p> <p>SSL_CTX_add_client_CA() adds the CA name extracted from <b>cacert</b> to the list of CAs sent to the client when requesting a client certificate for <b>ctx</b>.</p> <p>SSL_add_client_CA() adds the CA name extracted from <b>cacert</b> to the list of CAs sent to the client when requesting a client certificate for the chosen <b>ssl</b>, overriding the setting valid for <b>ssl</b>'s SSL_CTX object.</p> <p>SSL_get0_peer_CA_list() retrieves the list of CA names (if any) the peer has sent. This can be called on either the server or the client side. The returned list should not be freed by the caller.</p> <p>The "generic CA list" functions below are very similar to the "client CA list" functions except that they have an effect on both the server and client sides. The lists of CA names managed are separate - so you cannot (for example) set CA names using the "client CA list" functions and then get them using the "generic CA list" functions. Where a mix of the two types of functions has been used on the server side then the "client CA list" functions take precedence. Typically, on the server side, the "client CA list " functions should be used in preference.

If not set then 1 is used.</p> <p>The security framework disables or reject parameters inconsistent with the set security level. In the past this was difficult as applications had to set a number of distinct parameters (supported ciphers, supported curves supported signature algorithms) to achieve this end and some cases (DH parameter size for example) could not be checked at all.</p> <p>By setting an appropriate security level much of this complexity can be avoided.</p> <p>The bits of security limits affect all relevant parameters including cipher suite encryption algorithms, supported ECC curves, supported signature algorithms, DH parameter sizes, certificate key sizes and signature algorithms. This limit applies no matter what other custom settings an application has set: so if the cipher suite is set to <b>ALL</b> then only cipher suites consistent with the security level are permissible.</p> <p>See SP800-57 for how the security limits are related to individual algorithms.</p> <p>Some security levels require large key sizes for non-ECC public key algorithms which can severely degrade performance. For example 256 bits of security requires the use of RSA keys of at least 15360 bits in size.</p> <p>Some restrictions can be gracefully handled: for example cipher suites offering insufficient security are not sent by the client and will not be selected by the server. Other restrictions such as the peer certificate key size or the DH parameter size will abort the handshake with a fatal alert.</p> <p>Attempts to set certificates or parameters with insufficient security are also blocked. For example trying to set a certificate using a 512 bit RSA key using SSL_CTX_use_certificate() at level 1. Applications which do not check the return values for errors will misbehave: for example it might appear that a certificate is not set at all because it had been rejected.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CTX_set_security_level() and SSL_set_security_level() do not return values.</p> <p>SSL_CTX_get_security_level() and SSL_get_security_level() return a integer that represents the security level with <b>SSL_CTX</b> or <b>SSL</b>, respectively.</p> <p>SSL_CTX_set_security_callback() and SSL_set_security_callback() do not return values.</p> <p>SSL_CTX_get_security_callback() and SSL_get_security_callback() return the pointer to the security callback or NULL if the callback is not set.</p> <p>SSL_CTX_get0_security_ex_data() and SSL_get0_security_ex_data() return the extra data pointer or NULL if the ex data is not set.</p> <h1 id="HISTORY">HISTORY</h1> <p>These functions were added in OpenSSL 1.1.0.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2014-2020 The OpenSSL Project Authors.

When the client wishes to resume it provides the unique id so that the server can retrieve the session information from its cache.</p> <p>When using stateless session tickets the server uses a session ticket encryption key to encrypt the session information. This encrypted data is sent to the client as a "ticket". When the client wishes to resume it sends the encrypted data back to the server. The server uses its key to decrypt the data and resume the session. In this way the server can operate statelessly - no session information needs to be cached locally.</p> <p>The TLSv1.3 protocol only supports tickets and does not directly support session ids. However, OpenSSL allows two modes of ticket operation in TLSv1.3: stateful and stateless. Stateless tickets work the same way as in TLSv1.2 and below. Stateful tickets mimic the session id behaviour available in TLSv1.2 and below. The session information is cached on the server and the session id is wrapped up in a ticket and sent back to the client. When the client wishes to resume, it presents a ticket in the same way as for stateless tickets. The server can then extract the session id from the ticket and retrieve the session information from its cache.</p> <p>By default OpenSSL will use stateless tickets. The SSL_OP_NO_TICKET option will cause stateless tickets to not be issued. In TLSv1.2 and below this means no ticket gets sent to the client at all. In TLSv1.3 a stateful ticket will be sent.

It admits multiple lookup mechanisms and efficient scaling performance with large numbers of certificates, and a great deal of flexibility in how validation and policy checks are performed.</p> <p><a href="../man3/X509_STORE_new.html">X509_STORE_new(3)</a> creates an empty <b>X509_STORE</b> structure, which contains no information about trusted certificates or where such certificates are located on disk, and is generally not usable. Normally, trusted certificates will be added to the <b>X509_STORE</b> to prepare it for use, via mechanisms such as X509_STORE_add_lookup() and X509_LOOKUP_file(), or PEM_read_bio_X509_AUX() and X509_STORE_add_cert(). CRLs can also be added, and many behaviors configured as desired.</p> <p>Once the <b>X509_STORE</b> is suitably configured, X509_STORE_CTX_new() is used to instantiate a single-use <b>X509_STORE_CTX</b> for each chain-building and verification operation. That process includes providing the end-entity certificate to be verified and an additional set of untrusted certificates that may be used in chain-building. As such, it is expected that the certificates included in the <b>X509_STORE</b> are certificates that represent trusted entities such as root certificate authorities (CAs). OpenSSL represents these trusted certificates internally as <b>X509</b> objects with an associated <b>X509_CERT_AUX</b>, as are produced by PEM_read_bio_X509_AUX() and similar routines that refer to X509_AUX. The public interfaces that operate on such trusted certificates still operate on pointers to <b>X509</b> objects, though.</p> <p>X509_STORE_add_cert() and X509_STORE_add_crl() add the respective object to the <b>X509_STORE</b>'s local storage. Untrusted objects should not be added in this way. The added object's reference count is incremented by one, hence the caller retains ownership of the object and needs to free it when it is no longer needed.</p> <p>X509_STORE_set_depth(), X509_STORE_set_flags(), X509_STORE_set_purpose(), X509_STORE_set_trust(), and X509_STORE_set1_param() set the default values for the corresponding values used in certificate chain validation. Their behavior is documented in the corresponding <b>X509_VERIFY_PARAM</b> manual pages, e.g., <a href="../man3/X509_VERIFY_PARAM_set_depth.html">X509_VERIFY_PARAM_set_depth(3)</a>.</p> <p>X509_STORE_add_lookup() finds or creates a <a href="../man3/X509_LOOKUP.html">X509_LOOKUP(3)</a> with the <a href="../man3/X509_LOOKUP_METHOD.html">X509_LOOKUP_METHOD(3)</a> <i>meth</i> and adds it to the <b>X509_STORE</b> <i>store</i>. This also associates the <b>X509_STORE</b> with the lookup, so <b>X509_LOOKUP</b> functions can look up objects in that store.</p> <p>X509_STORE_load_locations() loads trusted certificate(s) into an <b>X509_STORE</b> from a given file and/or directory path. It is permitted to specify just a file, just a directory, or both paths.

To do so the client should call the SSL_CTX_set_tlsext_status_type() function prior to the creation of any SSL objects. Alternatively an application can call the SSL_set_tlsext_status_type() function on an individual SSL object prior to the start of the handshake. Currently the only supported type is <b>TLSEXT_STATUSTYPE_ocsp</b>. This value should be passed in the <b>type</b> argument. Calling SSL_CTX_get_tlsext_status_type() will return the type <b>TLSEXT_STATUSTYPE_ocsp</b> previously set via SSL_CTX_set_tlsext_status_type() or -1 if not set.</p> <p>The client should additionally provide a callback function to decide what to do with the returned OCSP response by calling SSL_CTX_set_tlsext_status_cb(). The callback function should determine whether the returned OCSP response is acceptable or not. The callback will be passed as an argument the value previously set via a call to SSL_CTX_set_tlsext_status_arg(). Note that the callback will not be called in the event of a handshake where session resumption occurs (because there are no Certificates exchanged in such a handshake). The callback previously set via SSL_CTX_set_tlsext_status_cb() can be retrieved by calling SSL_CTX_get_tlsext_status_cb(), and the argument by calling SSL_CTX_get_tlsext_status_arg().</p> <p>On the client side SSL_get_tlsext_status_type() can be used to determine whether the client has previously called SSL_set_tlsext_status_type(). It will return <b>TLSEXT_STATUSTYPE_ocsp</b> if it has been called or -1 otherwise. On the server side SSL_get_tlsext_status_type() can be used to determine whether the client requested OCSP stapling. If the client requested it then this function will return <b>TLSEXT_STATUSTYPE_ocsp</b>, or -1 otherwise.</p> <p>The response returned by the server can be obtained via a call to SSL_get_tlsext_status_ocsp_resp(). The value <b>*resp</b> will be updated to point to the OCSP response data and the return value will be the length of that data. Typically a callback would obtain an OCSP_RESPONSE object from this data via a call to the d2i_OCSP_RESPONSE() function. If the server has not provided any response data then <b>*resp</b> will be NULL and the return value from SSL_get_tlsext_status_ocsp_resp() will be -1.</p> <p>A server application must also call the SSL_CTX_set_tlsext_status_cb() function if it wants to be able to provide clients with OCSP Certificate Status responses. Typically the server callback would obtain the server certificate that is being sent back to the client via a call to SSL_get_certificate(); obtain the OCSP response to be sent back; and then set that response data by calling SSL_set_tlsext_status_ocsp_resp(). A pointer to the response data should be provided in the <b>resp</b> argument, and the length of that data should be in the <b>len</b> argument.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The callback when used on the client side should return a negative value on error; 0 if the response is not acceptable (in which case the handshake will fail) or a positive value if it is acceptable.</p> <p>The callback when used on the server side should return with either SSL_TLSEXT_ERR_OK (meaning that the OCSP response that has been set should be returned), SSL_TLSEXT_ERR_NOACK (meaning that an OCSP response should not be returned) or SSL_TLSEXT_ERR_ALERT_FATAL (meaning that a fatal error has occurred).</p> <p>SSL_CTX_set_tlsext_status_cb(), SSL_CTX_set_tlsext_status_arg(), SSL_CTX_set_tlsext_status_type(), SSL_set_tlsext_status_type() and SSL_set_tlsext_status_ocsp_resp() return 0 on error or 1 on success.</p> <p>SSL_CTX_get_tlsext_status_type() returns the value previously set by SSL_CTX_set_tlsext_status_type(), or -1 if not set.</p> <p>SSL_get_tlsext_status_ocsp_resp() returns the length of the OCSP response data or -1 if there is no OCSP response data.</p> <p>SSL_get_tlsext_status_type() returns <b>TLSEXT_STATUSTYPE_ocsp</b> on the client side if SSL_set_tlsext_status_type() was previously called, or on the server side if the client requested OCSP stapling.

The <b>*status</b> value will be one of <b>V_OCSP_CERTSTATUS_GOOD</b>, <b>V_OCSP_CERTSTATUS_REVOKED</b> or <b>V_OCSP_CERTSTATUS_UNKNOWN</b>. The <b>*reason</b> and <b>*revtime</b> fields are only set if the status is <b>V_OCSP_CERTSTATUS_REVOKED</b>.

Where <b>idx</b> runs from 0 to OCSP_resp_count(bs) - 1.</p> <p>OCSP_resp_find() searches <b>bs</b> for <b>id</b> and returns the index of the first matching entry after <b>last</b> or starting from the beginning if <b>last</b> is -1.</p> <p>OCSP_single_get0_status() extracts the fields of <b>single</b> in <b>*reason</b>, <b>*revtime</b>, <b>*thisupd</b> and <b>*nextupd</b>.</p> <p>OCSP_resp_get0_produced_at() extracts the <b>producedAt</b> field from the single response <b>bs</b>.</p> <p>OCSP_resp_get0_signature() returns the signature from <b>bs</b>.</p> <p>OCSP_resp_get0_tbs_sigalg() returns the <b>signatureAlgorithm</b> from <b>bs</b>.</p> <p>OCSP_resp_get0_respdata() returns the <b>tbsResponseData</b> from <b>bs</b>.</p> <p>OCSP_resp_get0_certs() returns any certificates included in <b>bs</b>.</p> <p>OCSP_resp_get0_signer() attempts to retrieve the certificate that directly signed <b>bs</b>. The OCSP protocol does not require that this certificate is included in the <b>certs</b> field of the response, so additional certificates can be supplied in <b>extra_certs</b> if the certificates that may have signed the response are known via some out-of-band mechanism.</p> <p>OCSP_resp_get0_id() gets the responder id of <b>bs</b>. If the responder ID is a name then <*pname> is set to the name and <b>*pid</b> is set to NULL. If the responder ID is by key ID then <b>*pid</b> is set to the key ID and <b>*pname</b> is set to NULL. OCSP_resp_get1_id() leaves ownership of <b>*pid</b> and <b>*pname</b> with the caller, who is responsible for freeing them. Both functions return 1 in case of success and 0 in case of failure. If OCSP_resp_get1_id() returns 0, no freeing of the results is necessary.</p> <p>OCSP_check_validity() checks the validity of <b>thisupd</b> and <b>nextupd</b> values which will be typically obtained from OCSP_resp_find_status() or OCSP_single_get0_status(). If <b>sec</b> is nonzero it indicates how many seconds leeway should be allowed in the check. If <b>maxsec</b> is positive it indicates the maximum age of <b>thisupd</b> in seconds.</p> <p>OCSP_basic_verify() checks that the basic response message <b>bs</b> is correctly signed and that the signer certificate can be validated. It takes <b>st</b> as the trusted store and <b>certs</b> as a set of untrusted intermediate certificates. The function first tries to find the signer certificate of the response in <certs>. It also searches the certificates the responder may have included in <b>bs</b> unless the <b>flags</b> contain <b>OCSP_NOINTERN</b>. It fails if the signer certificate cannot be found. Next, the function checks the signature of <b>bs</b> and fails on error unless the <b>flags</b> contain <b>OCSP_NOSIGS</b>. Then the function already returns success if the <b>flags</b> contain <b>OCSP_NOVERIFY</b> or if the signer certificate was found in <b>certs</b> and the <b>flags</b> contain <b>OCSP_TRUSTOTHER</b>. Otherwise the function continues by validating the signer certificate. To this end, all certificates in <b>cert</b> and in <b>bs</b> are considered as untrusted certificates for the construction of the validation path for the signer certificate unless the <b>OCSP_NOCHAIN</b> flag is set. After successful path validation the function returns success if the <b>OCSP_NOCHECKS</b> flag is set. Otherwise it verifies that the signer certificate meets the OCSP issuer criteria including potential delegation. If this does not succeed and the <b>flags</b> do not contain <b>OCSP_NOEXPLICIT</b> the function checks for explicit trust for OCSP signing in the root CA certificate.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>OCSP_resp_find_status() returns 1 if <b>id</b> is found in <b>bs</b> and 0 otherwise.</p> <p>OCSP_resp_count() returns the total number of <b>OCSP_SINGLERESP</b> fields in <b>bs</b>.</p> <p>OCSP_resp_get0() returns a pointer to an <b>OCSP_SINGLERESP</b> structure or <b>NULL</b> if <b>idx</b> is out of range.</p> <p>OCSP_resp_find() returns the index of <b>id</b> in <b>bs</b> (which may be 0) or -1 if <b>id</b> was not found.</p> <p>OCSP_single_get0_status() returns the status of <b>single</b> or -1 if an error occurred.</p> <p>OCSP_resp_get0_signer() returns 1 if the signing certificate was located, or 0 on error.</p> <p>OCSP_basic_verify() returns 1 on success, 0 on error, or -1 on fatal error such as malloc failure.</p> <h1 id="NOTES">NOTES</h1> <p>Applications will typically call OCSP_resp_find_status() using the certificate ID of interest and then check its validity using OCSP_check_validity(). They can then take appropriate action based on the status of the certificate.</p> <p>An OCSP response for a certificate contains <b>thisUpdate</b> and <b>nextUpdate</b> fields. Normally the current time should be between these two values. To account for clock skew the <b>maxsec</b> field can be set to nonzero in OCSP_check_validity(). Some responders do not set the <b>nextUpdate</b> field, this would otherwise mean an ancient response would be considered valid: the <b>maxsec</b> parameter to OCSP_check_validity() can be used to limit the permitted age of responses.</p> <p>The values written to <b>*revtime</b>, <b>*thisupd</b> and <b>*nextupd</b> by OCSP_resp_find_status() and OCSP_single_get0_status() are internal pointers which <b>MUST NOT</b> be freed up by the calling application.

This represents code that can be started and executes until some event occurs. At that point the code can be paused and control returns to user code until some subsequent event indicates that the job can be resumed.</p> <p>The creation of an ASYNC_JOB is a relatively expensive operation. Therefore, for efficiency reasons, jobs can be created up front and reused many times. They are held in a pool until they are needed, at which point they are removed from the pool, used, and then returned to the pool when the job completes. If the user application is multi-threaded, then ASYNC_init_thread() may be called for each thread that will initiate asynchronous jobs. Before user code exits per-thread resources need to be cleaned up. This will normally occur automatically (see <a href="../man3/OPENSSL_init_crypto.html">OPENSSL_init_crypto(3)</a>) but may be explicitly initiated by using ASYNC_cleanup_thread(). No asynchronous jobs must be outstanding for the thread when ASYNC_cleanup_thread() is called. Failing to ensure this will result in memory leaks.</p> <p>The <b>max_size</b> argument limits the number of ASYNC_JOBs that will be held in the pool. If <b>max_size</b> is set to 0 then no upper limit is set. When an ASYNC_JOB is needed but there are none available in the pool already then one will be automatically created, as long as the total of ASYNC_JOBs managed by the pool does not exceed <b>max_size</b>. When the pool is first initialised <b>init_size</b> ASYNC_JOBs will be created immediately. If ASYNC_init_thread() is not called before the pool is first used then it will be called automatically with a <b>max_size</b> of 0 (no upper limit) and an <b>init_size</b> of 0 (no ASYNC_JOBs created up front).</p> <p>An asynchronous job is started by calling the ASYNC_start_job() function. Initially <b>*job</b> should be NULL. <b>ctx</b> should point to an ASYNC_WAIT_CTX object created through the <a href="../man3/ASYNC_WAIT_CTX_new.html">ASYNC_WAIT_CTX_new(3)</a> function. <b>ret</b> should point to a location where the return value of the asynchronous function should be stored on completion of the job. <b>func</b> represents the function that should be started asynchronously. The data pointed to by <b>args</b> and of size <b>size</b> will be copied and then passed as an argument to <b>func</b> when the job starts.

ASYNC_get_current_job() can be used to get a pointer to the currently executing ASYNC_JOB. If no job is currently executing then this will return NULL.</p> <p>If executing within the context of a job (i.e. having been called directly or indirectly by the function "func" passed as an argument to ASYNC_start_job()) then ASYNC_pause_job() will immediately return control to the calling application with ASYNC_PAUSE returned from the ASYNC_start_job() call. A subsequent call to ASYNC_start_job passing in the relevant ASYNC_JOB in the <b>*job</b> parameter will resume execution from the ASYNC_pause_job() call. If ASYNC_pause_job() is called whilst not within the context of a job then no action is taken and ASYNC_pause_job() returns immediately.</p> <p>ASYNC_get_wait_ctx() can be used to get a pointer to the ASYNC_WAIT_CTX for the <b>job</b>. ASYNC_WAIT_CTXs can have a "wait" file descriptor associated with them. Applications can wait for the file descriptor to be ready for "read" using a system function call such as select or poll (being ready for "read" indicates that the job should be resumed). If no file descriptor is made available then an application will have to periodically "poll" the job by attempting to restart it to see if it is ready to continue.</p> <p>An example of typical usage might be an async capable engine. User code would initiate cryptographic operations. The engine would initiate those operations asynchronously and then call <a href="../man3/ASYNC_WAIT_CTX_set_wait_fd.html">ASYNC_WAIT_CTX_set_wait_fd(3)</a> followed by ASYNC_pause_job() to return control to the user code. The user code can then perform other tasks or wait for the job to be ready by calling "select" or other similar function on the wait file descriptor. The engine can signal to the user code that the job should be resumed by making the wait file descriptor "readable". Once resumed the engine should clear the wake signal on the wait file descriptor.</p> <p>The ASYNC_block_pause() function will prevent the currently active job from pausing. The block will remain in place until a subsequent call to ASYNC_unblock_pause(). These functions can be nested, e.g. if you call ASYNC_block_pause() twice then you must call ASYNC_unblock_pause() twice in order to re-enable pausing. If these functions are called while there is no currently active job then they have no effect. This functionality can be useful to avoid deadlock scenarios. For example during the execution of an ASYNC_JOB an application acquires a lock. It then calls some cryptographic function which invokes ASYNC_pause_job(). This returns control back to the code that created the ASYNC_JOB. If that code then attempts to acquire the same lock before resuming the original job then a deadlock can occur. By calling ASYNC_block_pause() immediately after acquiring the lock and ASYNC_unblock_pause() immediately before releasing it then this situation cannot occur.</p> <p>Some platforms cannot support async operations. The ASYNC_is_capable() function can be used to detect whether the current platform is async capable or not.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>ASYNC_init_thread returns 1 on success or 0 otherwise.</p> <p>ASYNC_start_job returns one of ASYNC_ERR, ASYNC_NO_JOBS, ASYNC_PAUSE or ASYNC_FINISH as described above.</p> <p>ASYNC_pause_job returns 0 if an error occurred or 1 on success. If called when not within the context of an ASYNC_JOB then this is counted as success so 1 is returned.</p> <p>ASYNC_get_current_job returns a pointer to the currently executing ASYNC_JOB or NULL if not within the context of a job.</p> <p>ASYNC_get_wait_ctx() returns a pointer to the ASYNC_WAIT_CTX for the job.</p> <p>ASYNC_is_capable() returns 1 if the current platform is async capable or 0 otherwise.</p> <h1 id="NOTES">NOTES</h1> <p>On Windows platforms the openssl/async.h header is dependent on some of the types customarily made available by including windows.h.

For algorithms which do not support streaming (e.g. PureEdDSA) it is the only way to verify data.</p> <p>In previous versions of OpenSSL there was a link between message digest types and public key algorithms.

It verifies a PKCS#7 signedData structure given in <i>p7</i>. The optional <i>certs</i> parameter refers to a set of certificates in which to search for signer's certificates. <i>p7</i> may contain extra untrusted CA certificates that may be used for chain building as well as CRLs that may be used for certificate validation. <i>store</i> may be NULL or point to the trusted certificate store to use for chain verification. <i>indata</i> refers to the signed data if the content is detached from <i>p7</i>. Otherwise <i>indata</i> should be NULL, and then the signed data must be in <i>p7</i>. The content is written to the BIO <i>out</i> unless it is NULL. <i>flags</i> is an optional set of flags, which can be used to modify the operation.</p> <p>PKCS7_get0_signers() retrieves the signer's certificates from <i>p7</i>, it does <b>not</b> check their validity or whether any signatures are valid. The <i>certs</i> and <i>flags</i> parameters have the same meanings as in PKCS7_verify().</p> <h1 id="VERIFY-PROCESS">VERIFY PROCESS</h1> <p>Normally the verify process proceeds as follows.</p> <p>Initially some sanity checks are performed on <i>p7</i>. The type of <i>p7</i> must be SignedData. There must be at least one signature on the data and if the content is detached <i>indata</i> cannot be NULL. If the content is not detached and <i>indata</i> is not NULL then the structure has both embedded and external content. To treat this as an error, use the flag <b>PKCS7_NO_DUAL_CONTENT</b>. The default behavior allows this, for compatibility with older versions of OpenSSL.</p> <p>An attempt is made to locate all the signer's certificates, first looking in the <i>certs</i> parameter (if it is not NULL). Then they are looked up in any certificates contained in the <i>p7</i> structure unless <b>PKCS7_NOINTERN</b> is set. If any signer's certificates cannot be located the operation fails.</p> <p>Each signer's certificate is chain verified using the <b>smimesign</b> purpose and using the trusted certificate store <i>store</i> if supplied. Any internal certificates in the message, which may have been added using <a href="../man3/PKCS7_add_certificate.html">PKCS7_add_certificate(3)</a>, are used as untrusted CAs unless <b>PKCS7_NOCHAIN</b> is set. If CRL checking is enabled in <i>store</i> and <b>PKCS7_NOCRL</b> is not set, any internal CRLs, which may have been added using <a href="../man3/PKCS7_add_crl.html">PKCS7_add_crl(3)</a>, are used in addition to attempting to look them up in <i>store</i>. If <i>store</i> is not NULL and any chain verify fails an error code is returned.</p> <p>Finally the signed content is read (and written to <i>out</i> unless it is NULL) and the signature is checked.</p> <p>If all signatures verify correctly then the function is successful.</p> <p>Any of the following flags (ored together) can be passed in the <i>flags</i> parameter to change the default verify behaviour. Only the flag <b>PKCS7_NOINTERN</b> is meaningful to PKCS7_get0_signers().</p> <p>If <b>PKCS7_NOINTERN</b> is set the certificates in the message itself are not searched when locating the signer's certificates. This means that all the signer's certificates must be in the <i>certs</i> parameter.</p> <p>If <b>PKCS7_NOCRL</b> is set and CRL checking is enabled in <i>store</i> then any CRLs in the message itself are ignored.</p> <p>If the <b>PKCS7_TEXT</b> flag is set MIME headers for type <code>text/plain</code> are deleted from the content. If the content is not of type <code>text/plain</code> then an error is returned.</p> <p>If <b>PKCS7_NOVERIFY</b> is set the signer's certificates are not chain verified.</p> <p>If <b>PKCS7_NOCHAIN</b> is set then the certificates contained in the message are not used as untrusted CAs. This means that the whole verify chain (apart from the signer's certificates) must be contained in the trusted store.</p> <p>If <b>PKCS7_NOSIGS</b> is set then the signatures on the data are not checked.</p> <h1 id="NOTES">NOTES</h1> <p>One application of <b>PKCS7_NOINTERN</b> is to only accept messages signed by a small number of certificates. The acceptable certificates would be passed in the <i>certs</i> parameter. In this case if the signer's certificate is not one of the certificates supplied in <i>certs</i> then the verify will fail because the signer cannot be found.</p> <p>Care should be taken when modifying the default verify behaviour, for example setting <b>PKCS7_NOVERIFY|PKCS7_NOSIGS</b> will totally disable all verification and any signed message will be considered valid. This combination is however useful if one merely wishes to write the content to <i>out</i> and its validity is not considered important.</p> <p>Chain verification should arguably be performed using the signing time rather than the current time. However, since the signing time is supplied by the signer it cannot be trusted without additional evidence (such as a trusted timestamp).</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>PKCS7_verify() returns 1 for a successful verification and 0 if an error occurs.</p> <p>PKCS7_get0_signers() returns all signers or NULL if an error occurred.</p> <p>The error can be obtained from <a href="../man3/ERR_get_error.html">ERR_get_error(3)</a>.</p> <h1 id="BUGS">BUGS</h1> <p>The trusted certificate store is not searched for the signer's certificates.

An ASYNC_WAIT_CTX object represents an asynchronous "session", i.e. a related set of crypto operations. For example in SSL terms this would have a one-to-one correspondence with an SSL connection.</p> <p>Application code must create an ASYNC_WAIT_CTX using the ASYNC_WAIT_CTX_new() function prior to calling ASYNC_start_job() (see <a href="../man3/ASYNC_start_job.html">ASYNC_start_job(3)</a>). When the job is started it is associated with the ASYNC_WAIT_CTX for the duration of that job. An ASYNC_WAIT_CTX should only be used for one ASYNC_JOB at any one time, but can be reused after an ASYNC_JOB has finished for a subsequent ASYNC_JOB. When the session is complete (e.g. the SSL connection is closed), application code cleans up with ASYNC_WAIT_CTX_free().</p> <p>ASYNC_WAIT_CTXs can have "wait" file descriptors associated with them. Calling ASYNC_WAIT_CTX_get_all_fds() and passing in a pointer to an ASYNC_WAIT_CTX in the <b>ctx</b> parameter will return the wait file descriptors associated with that job in <b>*fd</b>. The number of file descriptors returned will be stored in <b>*numfds</b>. It is the caller's responsibility to ensure that sufficient memory has been allocated in <b>*fd</b> to receive all the file descriptors. Calling ASYNC_WAIT_CTX_get_all_fds() with a NULL <b>fd</b> value will return no file descriptors but will still populate <b>*numfds</b>. Therefore, application code is typically expected to call this function twice: once to get the number of fds, and then again when sufficient memory has been allocated. If only one asynchronous engine is being used then normally this call will only ever return one fd. If multiple asynchronous engines are being used then more could be returned.</p> <p>The function ASYNC_WAIT_CTX_get_changed_fds() can be used to detect if any fds have changed since the last call time ASYNC_start_job() returned an ASYNC_PAUSE result (or since the ASYNC_WAIT_CTX was created if no ASYNC_PAUSE result has been received). The <b>numaddfds</b> and <b>numdelfds</b> parameters will be populated with the number of fds added or deleted respectively. <b>*addfd</b> and <b>*delfd</b> will be populated with the list of added and deleted fds respectively. Similarly to ASYNC_WAIT_CTX_get_all_fds() either of these can be NULL, but if they are not NULL then the caller is responsible for ensuring sufficient memory is allocated.</p> <p>Implementors of async aware code (e.g. engines) are encouraged to return a stable fd for the lifetime of the ASYNC_WAIT_CTX in order to reduce the "churn" of regularly changing fds - although no guarantees of this are provided to applications.</p> <p>Applications can wait for the file descriptor to be ready for "read" using a system function call such as select or poll (being ready for "read" indicates that the job should be resumed). If no file descriptor is made available then an application will have to periodically "poll" the job by attempting to restart it to see if it is ready to continue.</p> <p>Async aware code (e.g. engines) can get the current ASYNC_WAIT_CTX from the job via <a href="../man3/ASYNC_get_wait_ctx.html">ASYNC_get_wait_ctx(3)</a> and provide a file descriptor to use for waiting on by calling ASYNC_WAIT_CTX_set_wait_fd(). Typically this would be done by an engine immediately prior to calling ASYNC_pause_job() and not by end user code. An existing association with a file descriptor can be obtained using ASYNC_WAIT_CTX_get_fd() and cleared using ASYNC_WAIT_CTX_clear_fd(). Both of these functions requires a <b>key</b> value which is unique to the async aware code. This could be any unique value but a good candidate might be the <b>ENGINE *</b> for the engine. The <b>custom_data</b> parameter can be any value, and will be returned in a subsequent call to ASYNC_WAIT_CTX_get_fd(). The ASYNC_WAIT_CTX_set_wait_fd() function also expects a pointer to a "cleanup" routine. This can be NULL but if provided will automatically get called when the ASYNC_WAIT_CTX is freed, and gives the engine the opportunity to close the fd or any other resources. Note: The "cleanup" routine does not get called if the fd is cleared directly via a call to ASYNC_WAIT_CTX_clear_fd().</p> <p>An example of typical usage might be an async capable engine. User code would initiate cryptographic operations. The engine would initiate those operations asynchronously and then call ASYNC_WAIT_CTX_set_wait_fd() followed by ASYNC_pause_job() to return control to the user code. The user code can then perform other tasks or wait for the job to be ready by calling "select" or other similar function on the wait file descriptor. The engine can signal to the user code that the job should be resumed by making the wait file descriptor "readable". Once resumed the engine should clear the wake signal on the wait file descriptor.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>ASYNC_WAIT_CTX_new() returns a pointer to the newly allocated ASYNC_WAIT_CTX or NULL on error.</p> <p>ASYNC_WAIT_CTX_set_wait_fd, ASYNC_WAIT_CTX_get_fd, ASYNC_WAIT_CTX_get_all_fds, ASYNC_WAIT_CTX_get_changed_fds and ASYNC_WAIT_CTX_clear_fd all return 1 on success or 0 on error.</p> <h1 id="NOTES">NOTES</h1> <p>On Windows platforms the openssl/async.h header is dependent on some of the types customarily made available by including windows.h.

It uses a variable size key, but typically, 128 bit (16 byte) keys are considered good for strong encryption. Blowfish can be used in the same modes as DES (see <a href="../man7/des_modes.html">des_modes(7)</a>). Blowfish is currently one of the faster block ciphers. It is quite a bit faster than DES, and much faster than IDEA or RC2.</p> <p>Blowfish consists of a key setup phase and the actual encryption or decryption phase.</p> <p>BF_set_key() sets up the <b>BF_KEY</b> <b>key</b> using the <b>len</b> bytes long key at <b>data</b>.</p> <p>BF_ecb_encrypt() is the basic Blowfish encryption and decryption function. It encrypts or decrypts the first 64 bits of <b>in</b> using the key <b>key</b>, putting the result in <b>out</b>. <b>enc</b> decides if encryption (<b>BF_ENCRYPT</b>) or decryption (<b>BF_DECRYPT</b>) shall be performed. The vector pointed at by <b>in</b> and <b>out</b> must be 64 bits in length, no less. If they are larger, everything after the first 64 bits is ignored.</p> <p>The mode functions BF_cbc_encrypt(), BF_cfb64_encrypt() and BF_ofb64_encrypt() all operate on variable length data. They all take an initialization vector <b>ivec</b> which needs to be passed along into the next call of the same function for the same message. <b>ivec</b> may be initialized with anything, but the recipient needs to know what it was initialized with, or it won't be able to decrypt. Some programs and protocols simplify this, like SSH, where <b>ivec</b> is simply initialized to zero. BF_cbc_encrypt() operates on data that is a multiple of 8 bytes long, while BF_cfb64_encrypt() and BF_ofb64_encrypt() are used to encrypt a variable number of bytes (the amount does not have to be an exact multiple of 8). The purpose of the latter two is to simulate stream ciphers, and therefore, they need the parameter <b>num</b>, which is a pointer to an integer where the current offset in <b>ivec</b> is stored between calls. This integer must be initialized to zero when <b>ivec</b> is initialized.</p> <p>BF_cbc_encrypt() is the Cipher Block Chaining function for Blowfish. It encrypts or decrypts the 64 bits chunks of <b>in</b> using the key <b>schedule</b>, putting the result in <b>out</b>. <b>enc</b> decides if encryption (BF_ENCRYPT) or decryption (BF_DECRYPT) shall be performed. <b>ivec</b> must point at an 8 byte long initialization vector.</p> <p>BF_cfb64_encrypt() is the CFB mode for Blowfish with 64 bit feedback. It encrypts or decrypts the bytes in <b>in</b> using the key <b>schedule</b>, putting the result in <b>out</b>. <b>enc</b> decides if encryption (<b>BF_ENCRYPT</b>) or decryption (<b>BF_DECRYPT</b>) shall be performed. <b>ivec</b> must point at an 8 byte long initialization vector. <b>num</b> must point at an integer which must be initially zero.</p> <p>BF_ofb64_encrypt() is the OFB mode for Blowfish with 64 bit feedback. It uses the same parameters as BF_cfb64_encrypt(), which must be initialized the same way.</p> <p>BF_encrypt() and BF_decrypt() are the lowest level functions for Blowfish encryption. They encrypt/decrypt the first 64 bits of the vector pointed by <b>data</b>, using the key <b>key</b>. These functions should not be used unless you implement 'modes' of Blowfish. The alternative is to use BF_ecb_encrypt(). If you still want to use these functions, you should be aware that they take each 32-bit chunk in host-byte order, which is little-endian on little-endian platforms and big-endian on big-endian ones.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>None of the functions presented here return any value.</p> <h1 id="NOTE">NOTE</h1> <p>Applications should use the higher level functions <a href="../man3/EVP_EncryptInit.html">EVP_EncryptInit(3)</a> etc. instead of calling these functions directly.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/EVP_EncryptInit.html">EVP_EncryptInit(3)</a>, <a href="../man7/des_modes.html">des_modes(7)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2020 The OpenSSL Project Authors.

When constructing a curve using EC_GROUP_new (see <a href="../man3/EC_GROUP_new.html">EC_GROUP_new(3)</a>) an implementation method must be provided. The functions described here all return a const pointer to an <b>EC_METHOD</b> structure that can be passed to EC_GROUP_NEW. It is important that the correct implementation type for the form of curve selected is used.</p> <p>For F2^m curves there is only one implementation choice, i.e. EC_GF2_simple_method.</p> <p>For Fp curves the lowest common denominator implementation is the EC_GFp_simple_method implementation. All other implementations are based on this one. EC_GFp_mont_method builds on EC_GFp_simple_method but adds the use of montgomery multiplication (see <a href="../man3/BN_mod_mul_montgomery.html">BN_mod_mul_montgomery(3)</a>). EC_GFp_nist_method offers an implementation optimised for use with NIST recommended curves (NIST curves are available through EC_GROUP_new_by_curve_name as described in <a href="../man3/EC_GROUP_new.html">EC_GROUP_new(3)</a>).</p> <p>The functions EC_GFp_nistp224_method, EC_GFp_nistp256_method and EC_GFp_nistp521_method offer 64 bit optimised implementations for the NIST P224, P256 and P521 curves respectively. Note, however, that these implementations are not available on all platforms.</p> <p>EC_METHOD_get_field_type identifies what type of field the EC_METHOD structure supports, which will be either F2^m or Fp. If the field type is Fp then the value <b>NID_X9_62_prime_field</b> is returned. If the field type is F2^m then the value <b>NID_X9_62_characteristic_two_field</b> is returned.

However, even where the ClientHello callback is used, the servername callback is still necessary in order to acknowledge the servername requested by the client.</p> <p>SSL_CTX_set_tlsext_servername_callback() sets the application callback <b>cb</b> used by a server to perform any actions or configuration required based on the servername extension received in the incoming connection. When <b>cb</b> is NULL, SNI is not used.</p> <p>The servername callback should return one of the following values:</p> <dl> <dt id="SSL_TLSEXT_ERR_OK">SSL_TLSEXT_ERR_OK</dt> <dd> <p>This is used to indicate that the servername requested by the client has been accepted. Typically a server will call SSL_set_SSL_CTX() in the callback to set up a different configuration for the selected servername in this case.</p> </dd> <dt id="SSL_TLSEXT_ERR_ALERT_FATAL">SSL_TLSEXT_ERR_ALERT_FATAL</dt> <dd> <p>In this case the servername requested by the client is not accepted and the handshake will be aborted. The value of the alert to be used should be stored in the location pointed to by the <b>al</b> parameter to the callback. By default this value is initialised to SSL_AD_UNRECOGNIZED_NAME.</p> </dd> <dt id="SSL_TLSEXT_ERR_ALERT_WARNING">SSL_TLSEXT_ERR_ALERT_WARNING</dt> <dd> <p>If this value is returned then the servername is not accepted by the server. However, the handshake will continue and send a warning alert instead. The value of the alert should be stored in the location pointed to by the <b>al</b> parameter as for SSL_TLSEXT_ERR_ALERT_FATAL above. Note that TLSv1.3 does not support warning alerts, so if TLSv1.3 has been negotiated then this return value is treated the same way as SSL_TLSEXT_ERR_NOACK.</p> </dd> <dt id="SSL_TLSEXT_ERR_NOACK">SSL_TLSEXT_ERR_NOACK</dt> <dd> <p>This return value indicates that the servername is not accepted by the server. No alerts are sent and the server will not acknowledge the requested servername.</p> </dd> </dl> <p>SSL_CTX_set_tlsext_servername_arg() sets a context-specific argument to be passed into the callback (via the <b>arg</b> parameter) for this <b>SSL_CTX</b>.</p> <p>The behaviour of SSL_get_servername() depends on a number of different factors. In particular note that in TLSv1.3 the servername is negotiated in every handshake.

The servername, certificate and ALPN callbacks occur after a servername extension from the client is processed.</p> <p>SSL_get_servername_type() returns the servername type or -1 if no servername is present. Currently the only supported type (defined in RFC3546) is <b>TLSEXT_NAMETYPE_host_name</b>.</p> <p>SSL_set_tlsext_host_name() sets the server name indication ClientHello extension to contain the value <b>name</b>. The type of server name indication extension is set to <b>TLSEXT_NAMETYPE_host_name</b> (defined in RFC3546).</p> <h1 id="NOTES">NOTES</h1> <p>Several callbacks are executed during ClientHello processing, including the ClientHello, ALPN, and servername callbacks. The ClientHello callback is executed first, then the servername callback, followed by the ALPN callback.</p> <p>The SSL_set_tlsext_host_name() function should only be called on SSL objects that will act as clients; otherwise the configured <b>name</b> will be ignored.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CTX_set_tlsext_servername_callback() and SSL_CTX_set_tlsext_servername_arg() both always return 1 indicating success.

This has now been changed to return the servername requested in the original handshake.</p> <p>Also prior to 1.1.1e, if the client sent a servername in the first handshake but the server did not accept it, and then a second handshake occurred where TLSv1.2 resumption was successful then when called by the server it returned the servername requested in the original handshake.

The validity of the certificate and its trust level has to be checked by other means.</p> <p>X509_check_host() checks if the certificate Subject Alternative Name (SAN) or Subject CommonName (CN) matches the specified hostname, which must be encoded in the preferred name syntax described in section 3.5 of RFC 1034. By default, wildcards are supported and they match only in the left-most label; but they may match part of that label with an explicit prefix or suffix. For example, by default, the host <b>name</b> "www.example.com" would match a certificate with a SAN or CN value of "*.example.com", "w*.example.com" or "*w.example.com".</p> <p>Per section 6.4.2 of RFC 6125, <b>name</b> values representing international domain names must be given in A-label form. The <b>namelen</b> argument must be the number of characters in the name string or zero in which case the length is calculated with strlen(<b>name</b>). When <b>name</b> starts with a dot (e.g. ".example.com"), it will be matched by a certificate valid for any sub-domain of <b>name</b>, (see also <b>X509_CHECK_FLAG_SINGLE_LABEL_SUBDOMAINS</b> below).</p> <p>When the certificate is matched, and <b>peername</b> is not NULL, a pointer to a copy of the matching SAN or CN from the peer certificate is stored at the address passed in <b>peername</b>. The application is responsible for freeing the peername via OPENSSL_free() when it is no longer needed.</p> <p>X509_check_email() checks if the certificate matches the specified email <b>address</b>. Only the mailbox syntax of RFC 822 is supported, comments are not allowed, and no attempt is made to normalize quoted characters. The <b>addresslen</b> argument must be the number of characters in the address string or zero in which case the length is calculated with strlen(<b>address</b>).</p> <p>X509_check_ip() checks if the certificate matches a specified IPv4 or IPv6 address. The <b>address</b> array is in binary format, in network byte order. The length is either 4 (IPv4) or 16 (IPv6). Only explicitly marked addresses in the certificates are considered; IP addresses stored in DNS names and Common Names are ignored.</p> <p>X509_check_ip_asc() is similar, except that the NUL-terminated string <b>address</b> is first converted to the internal representation.</p> <p>The <b>flags</b> argument is usually 0.

If both <b>X509_CHECK_FLAG_ALWAYS_CHECK_SUBJECT</b> and <b>X509_CHECK_FLAG_NEVER_CHECK_SUBJECT</b> are specified, the latter takes precedence and the subject DN is not checked for matching names.</p> <p>If set, <b>X509_CHECK_FLAG_NO_WILDCARDS</b> disables wildcard expansion; this only applies to <b>X509_check_host</b>.</p> <p>If set, <b>X509_CHECK_FLAG_NO_PARTIAL_WILDCARDS</b> suppresses support for "*" as wildcard pattern in labels that have a prefix or suffix, such as: "www*" or "*www"; this only applies to <b>X509_check_host</b>.</p> <p>If set, <b>X509_CHECK_FLAG_MULTI_LABEL_WILDCARDS</b> allows a "*" that constitutes the complete label of a DNS name (e.g. "*.example.com") to match more than one label in <b>name</b>; this flag only applies to <b>X509_check_host</b>.</p> <p>If set, <b>X509_CHECK_FLAG_SINGLE_LABEL_SUBDOMAINS</b> restricts <b>name</b> values which start with ".", that would otherwise match any sub-domain in the peer certificate, to only match direct child sub-domains. Thus, for instance, with this flag set a <b>name</b> of ".example.com" would match a peer certificate with a DNS name of "www.example.com", but would not match a peer certificate with a DNS name of "www.sub.example.com"; this flag only applies to <b>X509_check_host</b>.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The functions return 1 for a successful match, 0 for a failed match and -1 for an internal error: typically a memory allocation failure or an ASN.1 decoding error.</p> <p>All functions can also return -2 if the input is malformed.

The raw signature and hash values are written to <b>*rsig</b> and <b>*rhash</b>.</p> <p>SSL_get_sigalgs() is similar to SSL_get_shared_sigalgs() except it returns information about all signature algorithms supported by <b>s</b> in the order they were sent by the peer.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_get_shared_sigalgs() and SSL_get_sigalgs() return the number of signature algorithms or <b>0</b> if the <b>idx</b> parameter is out of range.</p> <h1 id="NOTES">NOTES</h1> <p>These functions are typically called for debugging purposes (to report the peer's preferences) or where an application wants finer control over certificate selection. Most applications will rely on internal handling and will not need to call them.</p> <p>If an application is only interested in the highest preference shared signature algorithm it can just set <b>idx</b> to zero.</p> <p>Any or all of the parameters <b>psign</b>, <b>phash</b>, <b>psignhash</b>, <b>rsig</b> or <b>rhash</b> can be set to <b>NULL</b> if the value is not required. By setting them all to <b>NULL</b> and setting <b>idx</b> to zero the total number of signature algorithms can be determined: which can be zero.</p> <p>These functions must be called after the peer has sent a list of supported signature algorithms: after a client hello (for servers) or a certificate request (for clients). They can (for example) be called in the certificate callback.</p> <p>Only TLS 1.2, TLS 1.3 and DTLS 1.2 currently support signature algorithms. If these functions are called on an earlier version of TLS or DTLS zero is returned.</p> <p>The shared signature algorithms returned by SSL_get_shared_sigalgs() are ordered according to configuration and peer preferences.</p> <p>The raw values correspond to the on the wire form as defined by RFC5246 et al. The NIDs are OpenSSL equivalents. For example if the peer sent sha256(4) and rsa(1) then <b>*rhash</b> would be 4, <b>*rsign</b> 1, <b>*phash</b> NID_sha256, <b>*psig</b> NID_rsaEncryption and <b>*psighash</b> NID_sha256WithRSAEncryption.</p> <p>If a signature algorithm is not recognised the corresponding NIDs will be set to <b>NID_undef</b>. This may be because the value is not supported, is not an appropriate combination (for example MD5 and DSA) or the signature algorithm does not use a hash (for example Ed25519).</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/SSL_CTX_set_cert_cb.html">SSL_CTX_set_cert_cb(3)</a>, <a href="../man7/ssl.html">ssl(7)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2015-2018 The OpenSSL Project Authors.

It verifies a <b>CMS SignedData</b> structure contained in a structure of type <b>CMS_ContentInfo</b>. <i>cms</i> points to the <b>CMS_ContentInfo</b> structure to verify. The optional <i>certs</i> parameter refers to a set of certificates in which to search for signing certificates. <i>cms</i> may contain extra untrusted CA certificates that may be used for chain building as well as CRLs that may be used for certificate validation. <i>store</i> may be NULL or point to the trusted certificate store to use for chain verification. <i>indata</i> refers to the signed data if the content is detached from <i>cms</i>. Otherwise <i>indata</i> should be NULL and the signed data must be in <i>cms</i>. The content is written to the BIO <i>out</i> unless it is NULL. <i>flags</i> is an optional set of flags, which can be used to modify the operation.</p> <p>CMS_get0_signers() retrieves the signing certificate(s) from <i>cms</i>, it may only be called after a successful CMS_verify() operation.</p> <h1 id="VERIFY-PROCESS">VERIFY PROCESS</h1> <p>Normally the verify process proceeds as follows.</p> <p>Initially some sanity checks are performed on <i>cms</i>. The type of <i>cms</i> must be SignedData. There must be at least one signature on the data and if the content is detached <i>indata</i> cannot be NULL.</p> <p>An attempt is made to locate all the signing certificate(s), first looking in the <i>certs</i> parameter (if it is not NULL) and then looking in any certificates contained in the <i>cms</i> structure unless <b>CMS_NOINTERN</b> is set. If any signing certificate cannot be located the operation fails.</p> <p>Each signing certificate is chain verified using the <i>smimesign</i> purpose and using the trusted certificate store <i>store</i> if supplied. Any internal certificates in the message, which may have been added using <a href="../man3/CMS_add1_cert.html">CMS_add1_cert(3)</a>, are used as untrusted CAs. If CRL checking is enabled in <i>store</i> and <b>CMS_NOCRL</b> is not set, any internal CRLs, which may have been added using <a href="../man3/CMS_add1_crl.html">CMS_add1_crl(3)</a>, are used in addition to attempting to look them up in <i>store</i>. If <i>store</i> is not NULL and any chain verify fails an error code is returned.</p> <p>Finally the signed content is read (and written to <i>out</i> unless it is NULL) and the signature is checked.</p> <p>If all signatures verify correctly then the function is successful.</p> <p>Any of the following flags (ored together) can be passed in the <i>flags</i> parameter to change the default verify behaviour.</p> <p>If <b>CMS_NOINTERN</b> is set the certificates in the message itself are not searched when locating the signing certificate(s). This means that all the signing certificates must be in the <i>certs</i> parameter.</p> <p>If <b>CMS_NOCRL</b> is set and CRL checking is enabled in <i>store</i> then any CRLs in the message itself are ignored.</p> <p>If the <b>CMS_TEXT</b> flag is set MIME headers for type <b>text/plain</b> are deleted from the content. If the content is not of type <b>text/plain</b> then an error is returned.</p> <p>If <b>CMS_NO_SIGNER_CERT_VERIFY</b> is set the signing certificates are not chain verified.</p> <p>If <b>CMS_NO_ATTR_VERIFY</b> is set the signed attributes signature is not verified.</p> <p>If <b>CMS_NO_CONTENT_VERIFY</b> is set then the content digest is not checked.</p> <h1 id="NOTES">NOTES</h1> <p>One application of <b>CMS_NOINTERN</b> is to only accept messages signed by a small number of certificates. The acceptable certificates would be passed in the <i>certs</i> parameter. In this case if the signer certificate is not one of the certificates supplied in <i>certs</i> then the verify will fail because the signer cannot be found.</p> <p>In some cases the standard techniques for looking up and validating certificates are not appropriate: for example an application may wish to lookup certificates in a database or perform customised verification. This can be achieved by setting and verifying the signer certificates manually using the signed data utility functions.</p> <p>Care should be taken when modifying the default verify behaviour, for example setting <b>CMS_NO_CONTENT_VERIFY</b> will totally disable all content verification and any modified content will be considered valid. This combination is however useful if one merely wishes to write the content to <i>out</i> and its validity is not considered important.</p> <p>Chain verification should arguably be performed using the signing time rather than the current time. However, since the signing time is supplied by the signer it cannot be trusted without additional evidence (such as a trusted timestamp).</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>CMS_verify() returns 1 for a successful verification and 0 if an error occurred.</p> <p>CMS_get0_signers() returns all signers or NULL if an error occurred.</p> <p>The error can be obtained from <a href="../man3/ERR_get_error.html">ERR_get_error(3)</a></p> <h1 id="BUGS">BUGS</h1> <p>The trusted certificate store is not searched for the signing certificate.

The level and type of security guarantees depend on the operating system. It is a good idea to review the code and see if it addresses your threat model and concerns.</p> <p>If a secure heap is used, then private key <b>BIGNUM</b> values are stored there. This protects long-term storage of private keys, but will not necessarily put all intermediate values and computations there.</p> <p>CRYPTO_secure_malloc_init() creates the secure heap, with the specified <code>size</code> in bytes. The <code>minsize</code> parameter is the minimum size to allocate from the heap. Both <code>size</code> and <code>minsize</code> must be a power of two.</p> <p>CRYPTO_secure_malloc_initialized() indicates whether or not the secure heap as been initialized and is available.</p> <p>CRYPTO_secure_malloc_done() releases the heap and makes the memory unavailable to the process if all secure memory has been freed. It can take noticeably long to complete.</p> <p>OPENSSL_secure_malloc() allocates <code>num</code> bytes from the heap. If CRYPTO_secure_malloc_init() is not called, this is equivalent to calling OPENSSL_malloc(). It is a macro that expands to CRYPTO_secure_malloc() and adds the <code>__FILE__</code> and <code>__LINE__</code> parameters.</p> <p>OPENSSL_secure_zalloc() and CRYPTO_secure_zalloc() are like OPENSSL_secure_malloc() and CRYPTO_secure_malloc(), respectively, except that they call memset() to zero the memory before returning.</p> <p>OPENSSL_secure_free() releases the memory at <code>ptr</code> back to the heap. It must be called with a value previously obtained from OPENSSL_secure_malloc(). If CRYPTO_secure_malloc_init() is not called, this is equivalent to calling OPENSSL_free(). It exists for consistency with OPENSSL_secure_malloc() , and is a macro that expands to CRYPTO_secure_free() and adds the <code>__FILE__</code> and <code>__LINE__</code> parameters..</p> <p>OPENSSL_secure_clear_free() is similar to OPENSSL_secure_free() except that it has an additional <code>num</code> parameter which is used to clear the memory if it was not allocated from the secure heap. If CRYPTO_secure_malloc_init() is not called, this is equivalent to calling OPENSSL_clear_free().</p> <p>OPENSSL_secure_actual_size() tells the actual size allocated to the pointer; implementations may allocate more space than initially requested, in order to "round up" and reduce secure heap fragmentation.</p> <p>OPENSSL_secure_allocated() tells if a pointer is allocated in the secure heap.</p> <p>CRYPTO_secure_used() returns the number of bytes allocated in the secure heap.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>CRYPTO_secure_malloc_init() returns 0 on failure, 1 if successful, and 2 if successful but the heap could not be protected by memory mapping.</p> <p>CRYPTO_secure_malloc_initialized() returns 1 if the secure heap is available (that is, if CRYPTO_secure_malloc_init() has been called, but CRYPTO_secure_malloc_done() has not been called or failed) or 0 if not.</p> <p>OPENSSL_secure_malloc() and OPENSSL_secure_zalloc() return a pointer into the secure heap of the requested size, or <code>NULL</code> if memory could not be allocated.</p> <p>CRYPTO_secure_allocated() returns 1 if the pointer is in the secure heap, or 0 if not.</p> <p>CRYPTO_secure_malloc_done() returns 1 if the secure memory area is released, or 0 if not.</p> <p>OPENSSL_secure_free() and OPENSSL_secure_clear_free() return no values.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/OPENSSL_malloc.html">OPENSSL_malloc(3)</a>, <a href="../man3/BN_new.html">BN_new(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The OPENSSL_secure_clear_free() function was added in OpenSSL 1.1.0g.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2015-2016 The OpenSSL Project Authors.

OpenSSL implements support for the "use_srtp" DTLS extension defined in RFC5764. This provides a mechanism for establishing SRTP keying material, algorithms and parameters using DTLS. This capability may be used as part of an implementation that conforms to RFC5763. OpenSSL does not implement SRTP itself or RFC5763. Note that OpenSSL does not support the use of SRTP Master Key Identifiers (MKIs). Also note that this extension is only supported in DTLS. Any SRTP configuration will be ignored if a TLS connection is attempted.</p> <p>An OpenSSL client wishing to send the "use_srtp" extension should call SSL_CTX_set_tlsext_use_srtp() to set its use for all SSL objects subsequently created from an SSL_CTX. Alternatively a client may call SSL_set_tlsext_use_srtp() to set its use for an individual SSL object. The <b>profiles</b> parameters should point to a NUL-terminated, colon delimited list of SRTP protection profile names.</p> <p>The currently supported protection profile names are:</p> <dl> <dt id="SRTP_AES128_CM_SHA1_80">SRTP_AES128_CM_SHA1_80</dt> <dd> <p>This corresponds to SRTP_AES128_CM_HMAC_SHA1_80 defined in RFC5764.</p> </dd> <dt id="SRTP_AES128_CM_SHA1_32">SRTP_AES128_CM_SHA1_32</dt> <dd> <p>This corresponds to SRTP_AES128_CM_HMAC_SHA1_32 defined in RFC5764.</p> </dd> <dt id="SRTP_AEAD_AES_128_GCM">SRTP_AEAD_AES_128_GCM</dt> <dd> <p>This corresponds to the profile of the same name defined in RFC7714.</p> </dd> <dt id="SRTP_AEAD_AES_256_GCM">SRTP_AEAD_AES_256_GCM</dt> <dd> <p>This corresponds to the profile of the same name defined in RFC7714.</p> </dd> </dl> <p>Supplying an unrecognised protection profile name will result in an error.</p> <p>An OpenSSL server wishing to support the "use_srtp" extension should also call SSL_CTX_set_tlsext_use_srtp() or SSL_set_tlsext_use_srtp() to indicate the protection profiles that it is willing to negotiate.</p> <p>The currently configured list of protection profiles for either a client or a server can be obtained by calling SSL_get_srtp_profiles(). This returns a stack of SRTP_PROTECTION_PROFILE objects. The memory pointed to in the return value of this function should not be freed by the caller.</p> <p>After a handshake has been completed the negotiated SRTP protection profile (if any) can be obtained (on the client or the server) by calling SSL_get_selected_srtp_profile(). This function will return NULL if no SRTP protection profile was negotiated. The memory returned from this function should not be freed by the caller.</p> <p>If an SRTP protection profile has been successfully negotiated then the SRTP keying material (on both the client and server) should be obtained via a call to <a href="../man3/SSL_export_keying_material.html">SSL_export_keying_material(3)</a>. This call should provide a label value of "EXTRACTOR-dtls_srtp" and a NULL context value (use_context is 0). The total length of keying material obtained should be equal to two times the sum of the master key length and the salt length as defined for the protection profile in use. This provides the client write master key, the server write master key, the client write master salt and the server write master salt in that order.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CTX_set_tlsext_use_srtp() and SSL_set_tlsext_use_srtp() return 0 on success or 1 on error.</p> <p>SSL_get_srtp_profiles() returns a stack of SRTP_PROTECTION_PROFILE objects on success or NULL on error or if no protection profiles have been configured.</p> <p>SSL_get_selected_srtp_profile() returns a pointer to an SRTP_PROTECTION_PROFILE object if one has been negotiated or NULL otherwise.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/SSL_export_keying_material.html">SSL_export_keying_material(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2017-2018 The OpenSSL Project Authors.

Similarly it will also automatically deinitialise as required.</p> <p>However, there may be situations when explicit initialisation is desirable or needed, for example when some nondefault initialisation is required. The function OPENSSL_init_crypto() can be used for this purpose for libcrypto (see also <a href="../man3/OPENSSL_init_ssl.html">OPENSSL_init_ssl(3)</a> for the libssl equivalent).</p> <p>Numerous internal OpenSSL functions call OPENSSL_init_crypto().

Using this option suppresses that behaviour. This means that the application will have to clean up OpenSSL explicitly using OPENSSL_cleanup().</p> </dd> </dl> <p>Multiple options may be combined together in a single call to OPENSSL_init_crypto(). For example:</p> <pre><code> OPENSSL_init_crypto(OPENSSL_INIT_NO_ADD_ALL_CIPHERS | OPENSSL_INIT_NO_ADD_ALL_DIGESTS, NULL);</code></pre> <p>The OPENSSL_cleanup() function deinitialises OpenSSL (both libcrypto and libssl). All resources allocated by OpenSSL are freed. Typically there should be no need to call this function directly as it is initiated automatically on application exit. This is done via the standard C library atexit() function. In the event that the application will close in a manner that will not call the registered atexit() handlers then the application should call OPENSSL_cleanup() directly. Developers of libraries using OpenSSL are discouraged from calling this function and should instead, typically, rely on auto-deinitialisation. This is to avoid error conditions where both an application and a library it depends on both use OpenSSL, and the library deinitialises it before the application has finished using it.</p> <p>Once OPENSSL_cleanup() has been called the library cannot be reinitialised. Attempts to call OPENSSL_init_crypto() will fail and an ERR_R_INIT_FAIL error will be added to the error stack. Note that because initialisation has failed OpenSSL error strings will not be available, only an error code. This code can be put through the openssl errstr command line application to produce a human readable error (see <a href="../man1/errstr.html">errstr(1)</a>).</p> <p>The OPENSSL_atexit() function enables the registration of a function to be called during OPENSSL_cleanup(). Stop handlers are called after deinitialisation of resources local to a thread, but before other process wide resources are freed. In the event that multiple stop handlers are registered, no guarantees are made about the order of execution.</p> <p>The OPENSSL_thread_stop() function deallocates resources associated with the current thread. Typically this function will be called automatically by the library when the thread exits. This should only be called directly if resources should be freed at an earlier time, or under the circumstances described in the NOTES section below.</p> <p>The <b>OPENSSL_INIT_LOAD_CONFIG</b> flag will load a configuration file, as with <a href="../man3/CONF_modules_load_file.html">CONF_modules_load_file(3)</a> with NULL filename and application name and the <b>CONF_MFLAGS_IGNORE_MISSING_FILE</b>, <b>CONF_MFLAGS_IGNORE_RETURN_CODES</b> and <b>CONF_MFLAGS_DEFAULT_SECTION</b> flags. The filename, application name, and flags can be customized by providing a non-null <b>OPENSSL_INIT_SETTINGS</b> object. The object can be allocated via <b>OPENSSL_init_new()</b>. The <b>OPENSSL_INIT_set_config_filename()</b> function can be used to specify a nondefault filename, which is copied and need not refer to persistent storage. Similarly, OPENSSL_INIT_set_config_appname() can be used to specify a nondefault application name. Finally, OPENSSL_INIT_set_file_flags can be used to specify nondefault flags. If the <b>CONF_MFLAGS_IGNORE_RETURN_CODES</b> flag is not included, any errors in the configuration file will cause an error return from <b>OPENSSL_init_crypto</b> or indirectly <a href="../man3/OPENSSL_init_ssl.html">OPENSSL_init_ssl(3)</a>. The object can be released with OPENSSL_INIT_free() when done.</p> <h1 id="NOTES">NOTES</h1> <p>Resources local to a thread are deallocated automatically when the thread exits (e.g. in a pthreads environment, when pthread_exit() is called). On Windows platforms this is done in response to a DLL_THREAD_DETACH message being sent to the libcrypto32.dll entry point. Some windows functions may cause threads to exit without sending this message (for example ExitProcess()). If the application uses such functions, then the application must free up OpenSSL resources directly via a call to OPENSSL_thread_stop() on each thread. Similarly this message will also not be sent if OpenSSL is linked statically, and therefore applications using static linking should also call OPENSSL_thread_stop() on each thread. Additionally if OpenSSL is loaded dynamically via LoadLibrary() and the threads are not destroyed until after FreeLibrary() is called then each thread should call OPENSSL_thread_stop() prior to the FreeLibrary() call.</p> <p>On Linux/Unix where OpenSSL has been loaded via dlopen() and the application is multi-threaded and if dlclose() is subsequently called prior to the threads being destroyed then OpenSSL will not be able to deallocate resources associated with those threads. The application should either call OPENSSL_thread_stop() on each thread prior to the dlclose() call, or alternatively the original dlopen() call should use the RTLD_NODELETE flag (where available on the platform).</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The functions OPENSSL_init_crypto, OPENSSL_atexit() and OPENSSL_INIT_set_config_appname() return 1 on success or 0 on error.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/OPENSSL_init_ssl.html">OPENSSL_init_ssl(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The OPENSSL_init_crypto(), OPENSSL_cleanup(), OPENSSL_atexit(), OPENSSL_thread_stop(), OPENSSL_INIT_new(), OPENSSL_INIT_set_config_appname() and OPENSSL_INIT_free() functions were added in OpenSSL 1.1.0.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2016-2022 The OpenSSL Project Authors.

DTLSv1_listen() statelessly listens for new incoming DTLS connections. If a ClientHello is received that does not contain a cookie, then they respond with a request for a new ClientHello that does contain a cookie. If a ClientHello is received with a cookie that is verified then the function returns in order to enable the handshake to be completed (for example by using SSL_accept()).</p> <h1 id="NOTES">NOTES</h1> <p>Some transport protocols (such as UDP) can be susceptible to amplification attacks. Unlike TCP there is no initial connection setup in UDP that validates that the client can actually receive messages on its advertised source address. An attacker could forge its source IP address and then send handshake initiation messages to the server. The server would then send its response to the forged source IP. If the response messages are larger than the original message then the amplification attack has succeeded.</p> <p>If DTLS is used over UDP (or any datagram based protocol that does not validate the source IP) then it is susceptible to this type of attack. TLSv1.3 is designed to operate over a stream-based transport protocol (such as TCP). If TCP is being used then there is no need to use SSL_stateless(). However, some stream-based transport protocols (e.g. QUIC) may not validate the source address. In this case a TLSv1.3 application would be susceptible to this attack.</p> <p>As a countermeasure to this issue TLSv1.3 and DTLS include a stateless cookie mechanism. The idea is that when a client attempts to connect to a server it sends a ClientHello message. The server responds with a HelloRetryRequest (in TLSv1.3) or a HelloVerifyRequest (in DTLS) which contains a unique cookie. The client then resends the ClientHello, but this time includes the cookie in the message thus proving that the client is capable of receiving messages sent to that address. All of this can be done by the server without allocating any state, and thus without consuming expensive resources.</p> <p>OpenSSL implements this capability via the SSL_stateless() and DTLSv1_listen() functions. The <b>ssl</b> parameter should be a newly allocated SSL object with its read and write BIOs set, in the same way as might be done for a call to SSL_accept(). Typically, for DTLS, the read BIO will be in an "unconnected" state and thus capable of receiving messages from any peer.</p> <p>When a ClientHello is received that contains a cookie that has been verified, then these functions will return with the <b>ssl</b> parameter updated into a state where the handshake can be continued by a call to (for example) SSL_accept(). Additionally, for DTLSv1_listen(), the <b>BIO_ADDR</b> pointed to by <b>peer</b> will be filled in with details of the peer that sent the ClientHello. If the underlying BIO is unable to obtain the <b>BIO_ADDR</b> of the peer (for example because the BIO does not support this), then <b>*peer</b> will be cleared and the family set to AF_UNSPEC. Typically user code is expected to "connect" the underlying socket to the peer and continue the handshake in a connected state.</p> <p>Prior to calling DTLSv1_listen() user code must ensure that cookie generation and verification callbacks have been set up using <a href="../man3/SSL_CTX_set_cookie_generate_cb.html">SSL_CTX_set_cookie_generate_cb(3)</a> and <a href="../man3/SSL_CTX_set_cookie_verify_cb.html">SSL_CTX_set_cookie_verify_cb(3)</a> respectively. For SSL_stateless(), <a href="../man3/SSL_CTX_set_stateless_cookie_generate_cb.html">SSL_CTX_set_stateless_cookie_generate_cb(3)</a> and <a href="../man3/SSL_CTX_set_stateless_cookie_verify_cb.html">SSL_CTX_set_stateless_cookie_verify_cb(3)</a> must be used instead.</p> <p>Since DTLSv1_listen() operates entirely statelessly whilst processing incoming ClientHellos it is unable to process fragmented messages (since this would require the allocation of state). An implication of this is that DTLSv1_listen() <b>only</b> supports ClientHellos that fit inside a single datagram.</p> <p>For SSL_stateless() if an entire ClientHello message cannot be read without the "read" BIO becoming empty then the SSL_stateless() call will fail. It is the application's responsibility to ensure that data read from the "read" BIO during a single SSL_stateless() call is all from the same peer.</p> <p>SSL_stateless() will fail (with a 0 return value) if some TLS version less than TLSv1.3 is used.</p> <p>Both SSL_stateless() and DTLSv1_listen() will clear the error queue when they start.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>For SSL_stateless() a return value of 1 indicates success and the <b>ssl</b> object will be set up ready to continue the handshake. A return value of 0 or -1 indicates failure. If the value is 0 then a HelloRetryRequest was sent. A value of -1 indicates any other error. User code may retry the SSL_stateless() call.</p> <p>For DTLSv1_listen() a return value of >= 1 indicates success. The <b>ssl</b> object will be set up ready to continue the handshake. the <b>peer</b> value will also be filled in.</p> <p>A return value of 0 indicates a non-fatal error. This could (for example) be because of nonblocking IO, or some invalid message having been received from a peer. Errors may be placed on the OpenSSL error queue with further information if appropriate. Typically user code is expected to retry the call to DTLSv1_listen() in the event of a non-fatal error.</p> <p>A return value of <0 indicates a fatal error. This could (for example) be because of a failure to allocate sufficient memory for the operation.</p> <p>For DTLSv1_listen(), prior to OpenSSL 1.1.0, fatal and non-fatal errors both produce return codes <= 0 (in typical implementations user code treats all errors as non-fatal), whilst return codes >0 indicate success.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/SSL_CTX_set_cookie_generate_cb.html">SSL_CTX_set_cookie_generate_cb(3)</a>, <a href="../man3/SSL_CTX_set_cookie_verify_cb.html">SSL_CTX_set_cookie_verify_cb(3)</a>, <a href="../man3/SSL_CTX_set_stateless_cookie_generate_cb.html">SSL_CTX_set_stateless_cookie_generate_cb(3)</a>, <a href="../man3/SSL_CTX_set_stateless_cookie_verify_cb.html">SSL_CTX_set_stateless_cookie_verify_cb(3)</a>, <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a>, <a href="../man3/SSL_accept.html">SSL_accept(3)</a>, <a href="../man7/ssl.html">ssl(7)</a>, <a href="../man7/bio.html">bio(7)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The SSL_stateless() function was added in OpenSSL 1.1.1.</p> <p>The DTLSv1_listen() return codes were clarified in OpenSSL 1.1.0.

In TLSv1.3 the same is true, but sessions are established after the main handshake has occurred. The server will send the session information to the client at a time of its choosing, which may be some while after the initial connection is established (or never). Calling these functions on the client side in TLSv1.3 before the session has been established will still return an SSL_SESSION object but that object cannot be used for resuming the session. See <a href="../man3/SSL_SESSION_is_resumable.html">SSL_SESSION_is_resumable(3)</a> for information on how to determine whether an SSL_SESSION object can be used for resumption or not.</p> <p>Additionally, in TLSv1.3, a server can send multiple messages that establish a session for a single connection. In that case, on the client side, the above functions will only return information on the last session that was received. On the server side they will only return information on the last session that was sent, or if no session tickets were sent then the session for the current connection.</p> <p>The preferred way for applications to obtain a resumable SSL_SESSION object is to use a new session callback as described in <a href="../man3/SSL_CTX_sess_set_new_cb.html">SSL_CTX_sess_set_new_cb(3)</a>. The new session callback is only invoked when a session is actually established, so this avoids the problem described above where an application obtains an SSL_SESSION object that cannot be used for resumption in TLSv1.3. It also enables applications to obtain information about all sessions sent by the server.</p> <p>A session will be automatically removed from the session cache and marked as non-resumable if the connection is not closed down cleanly, e.g. if a fatal error occurs on the connection or <a href="../man3/SSL_shutdown.html">SSL_shutdown(3)</a> is not called prior to <a href="../man3/SSL_free.html">SSL_free(3)</a>.</p> <p>In TLSv1.3 it is recommended that each SSL_SESSION object is only used for resumption once.</p> <p>SSL_get0_session() returns a pointer to the actual session. As the reference counter is not incremented, the pointer is only valid while the connection is in use. If <a href="../man3/SSL_clear.html">SSL_clear(3)</a> or <a href="../man3/SSL_free.html">SSL_free(3)</a> is called, the session may be removed completely (if considered bad), and the pointer obtained will become invalid. Even if the session is valid, it can be removed at any time due to timeout during <a href="../man3/SSL_CTX_flush_sessions.html">SSL_CTX_flush_sessions(3)</a>.</p> <p>If the data is to be kept, SSL_get1_session() will increment the reference count, so that the session will not be implicitly removed by other operations but stays in memory. In order to remove the session <a href="../man3/SSL_SESSION_free.html">SSL_SESSION_free(3)</a> must be explicitly called once to decrement the reference count again.</p> <p>SSL_SESSION objects keep internal link information about the session cache list, when being inserted into one SSL_CTX object's session cache. One SSL_SESSION object, regardless of its reference count, must therefore only be used with one SSL_CTX object (and the SSL objects created from this SSL_CTX object).</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The following return values can occur:</p> <dl> <dt id="NULL">NULL</dt> <dd> <p>There is no session available in <b>ssl</b>.</p> </dd> <dt id="Pointer-to-an-SSL_SESSION">Pointer to an SSL_SESSION</dt> <dd> <p>The return value points to the data of an SSL session.</p> </dd> </dl> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ssl.html">ssl(7)</a>, <a href="../man3/SSL_free.html">SSL_free(3)</a>, <a href="../man3/SSL_clear.html">SSL_clear(3)</a>, <a href="../man3/SSL_SESSION_free.html">SSL_SESSION_free(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2021 The OpenSSL Project Authors.

For example, the callback function will never see messages that are considered too large to be processed.</p> <p>Due to automatic protocol version negotiation, <i>version</i> is not necessarily the protocol version used by the sender of the message: If a TLS 1.0 ClientHello message is received by an SSL 3.0-only server, <i>version</i> will be <b>SSL3_VERSION</b>.</p> <p>Pseudo content type values may be sent at various points during the processing of data.

In encrypted TLSv1.3 records the content type in the record header is always SSL3_RT_APPLICATION_DATA.

A completed operation will result in data appearing as "read ready" on the file descriptor (no actual data should be read from the file descriptor). This function should only be called if the SSL object is currently waiting for asynchronous work to complete (i.e. SSL_ERROR_WANT_ASYNC has been received - see <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a>). Typically the list will only contain one file descriptor. However, if multiple asynchronous capable engines are in use then more than one is possible. The number of file descriptors returned is stored in <b>*numfds</b> and the file descriptors themselves are in <b>*fds</b>. The <b>fds</b> parameter may be NULL in which case no file descriptors are returned but <b>*numfds</b> is still populated.

Similar to SSL_get_all_async_fds() it is the callers responsibility to ensure that <b>*addfd</b> and <b>*delfd</b> have sufficient memory allocated, although they may be NULL.

It is the job of the client_cert_cb() to store information about the state of the last call, if required to continue.</p> <h1 id="NOTES">NOTES</h1> <p>During a handshake (or renegotiation) a server may request a certificate from the client. A client certificate must only be sent, when the server did send the request.</p> <p>When a certificate was set using the <a href="../man3/SSL_CTX_use_certificate.html">SSL_CTX_use_certificate(3)</a> family of functions, it will be sent to the server. The TLS standard requires that only a certificate is sent, if it matches the list of acceptable CAs sent by the server. This constraint is violated by the default behavior of the OpenSSL library. Using the callback function it is possible to implement a proper selection routine or to allow a user interaction to choose the certificate to be sent.</p> <p>If a callback function is defined and no certificate was yet defined for the SSL object, the callback function will be called. If the callback function returns a certificate, the OpenSSL library will try to load the private key and certificate data into the SSL object using the SSL_use_certificate() and SSL_use_private_key() functions. Thus it will permanently install the certificate and key for this SSL object. It will not be reset by calling <a href="../man3/SSL_clear.html">SSL_clear(3)</a>. If the callback returns no certificate, the OpenSSL library will not send a certificate.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CTX_get_client_cert_cb() returns function pointer of client_cert_cb() or NULL if the callback is not set.</p> <h1 id="BUGS">BUGS</h1> <p>The client_cert_cb() cannot return a complete certificate chain, it can only return one client certificate. If the chain only has a length of 2, the root CA certificate may be omitted according to the TLS standard and thus a standard conforming answer can be sent to the server. For a longer chain, the client must send the complete chain (with the option to leave out the root CA certificate). This can only be accomplished by either adding the intermediate CA certificates into the trusted certificate store for the SSL_CTX object (resulting in having to add CA certificates that otherwise maybe would not be trusted), or by adding the chain certificates using the <a href="../man3/SSL_CTX_add_extra_chain_cert.html">SSL_CTX_add_extra_chain_cert(3)</a> function, which is only available for the SSL_CTX object as a whole and that therefore probably can only apply for one client certificate, making the concept of the callback function (to allow the choice from several certificates) questionable.</p> <p>Once the SSL object has been used in conjunction with the callback function, the certificate will be set for the SSL object and will not be cleared even when <a href="../man3/SSL_clear.html">SSL_clear(3)</a> is being called. It is therefore mandatory to destroy the SSL object using <a href="../man3/SSL_free.html">SSL_free(3)</a> and create a new one to return to the previous state.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ssl.html">ssl(7)</a>, <a href="../man3/SSL_CTX_use_certificate.html">SSL_CTX_use_certificate(3)</a>, <a href="../man3/SSL_CTX_add_extra_chain_cert.html">SSL_CTX_add_extra_chain_cert(3)</a>, <a href="../man3/SSL_get_client_CA_list.html">SSL_get_client_CA_list(3)</a>, <a href="../man3/SSL_clear.html">SSL_clear(3)</a>, <a href="../man3/SSL_free.html">SSL_free(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2002-2018 The OpenSSL Project Authors.

It copies as many bytes as it can of this value into the buffer provided in <b>out</b>, which must have at least <b>outlen</b> bytes available. It returns the total number of bytes that were actually copied. If <b>outlen</b> is zero, SSL_get_client_random() copies nothing, and returns the total size of the client_random value.</p> <p>SSL_get_server_random() behaves the same, but extracts the random value sent from the server to the client during the initial SSL/TLS handshake.</p> <p>SSL_SESSION_get_master_key() behaves the same, but extracts the master secret used to guarantee the security of the SSL/TLS session. This one can be dangerous if misused; see NOTES below.</p> <p>SSL_SESSION_set1_master_key() sets the master key value associated with the SSL_SESSION <b>sess</b>. For example, this could be used to set up a session based PSK (see <a href="../man3/SSL_CTX_set_psk_use_session_callback.html">SSL_CTX_set_psk_use_session_callback(3)</a>). The master key of length <b>len</b> should be provided at <b>in</b>. The supplied master key is copied by the function, so the caller is responsible for freeing and cleaning any memory associated with <b>in</b>. The caller must ensure that the length of the key is suitable for the ciphersuite associated with the SSL_SESSION.</p> <h1 id="NOTES">NOTES</h1> <p>You probably shouldn't use these functions.</p> <p>These functions expose internal values from the TLS handshake, for use in low-level protocols. You probably should not use them, unless you are implementing something that needs access to the internal protocol details.</p> <p>Despite the names of SSL_get_client_random() and SSL_get_server_random(), they ARE NOT random number generators. Instead, they return the mostly-random values that were already generated and used in the TLS protocol. Using them in place of RAND_bytes() would be grossly foolish.</p> <p>The security of your TLS session depends on keeping the master key secret: do not expose it, or any information about it, to anybody.

This also applies to DTLS and pipelining (see <a href="../man3/SSL_CTX_set_split_send_fragment.html">SSL_CTX_set_split_send_fragment(3)</a>). These additional bytes will be buffered by OpenSSL but will remain unprocessed until they are needed. As these bytes are still in an unprocessed state SSL_pending() will ignore them.

Note that it is possible for SSL_has_pending() to return 1, and then a subsequent call to SSL_read_ex() or SSL_read() to return no data because the unprocessed buffered data when processed yielded no application data (for example this can happen during renegotiation). It is also possible in this scenario for SSL_has_pending() to continue to return 1 even after an SSL_read_ex() or SSL_read() call because the buffered and unprocessed data is not yet processable (e.g. because OpenSSL has only received a partial record so far).</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_pending() returns the number of buffered and processed application data bytes that are pending and are available for immediate read.

It sends the close_notify shutdown alert to the peer.</p> <h1 id="NOTES">NOTES</h1> <p>SSL_shutdown() tries to send the close_notify shutdown alert to the peer. Whether the operation succeeds or not, the SSL_SENT_SHUTDOWN flag is set and a currently open session is considered closed and good and will be kept in the session cache for further reuse.</p> <p>Note that SSL_shutdown() must not be called if a previous fatal error has occurred on a connection i.e. if SSL_get_error() has returned SSL_ERROR_SYSCALL or SSL_ERROR_SSL.</p> <p>The shutdown procedure consists of two steps: sending of the close_notify shutdown alert, and reception of the peer's close_notify shutdown alert. The order of those two steps depends on the application.</p> <p>It is acceptable for an application to only send its shutdown alert and then close the underlying connection without waiting for the peer's response. This way resources can be saved, as the process can already terminate or serve another connection. This should only be done when it is known that the other side will not send more data, otherwise there is a risk of a truncation attack.</p> <p>When a client only writes and never reads from the connection, and the server has sent a session ticket to establish a session, the client might not be able to resume the session because it did not received and process the session ticket from the server. In case the application wants to be able to resume the session, it is recommended to do a complete shutdown procedure (bidirectional close_notify alerts).</p> <p>When the underlying connection shall be used for more communications, the complete shutdown procedure must be performed, so that the peers stay synchronized.</p> <p>SSL_shutdown() only closes the write direction. It is not possible to call SSL_write() after calling SSL_shutdown(). The read direction is closed by the peer.</p> <h2 id="First-to-close-the-connection">First to close the connection</h2> <p>When the application is the first party to send the close_notify alert, SSL_shutdown() will only send the alert and then set the SSL_SENT_SHUTDOWN flag (so that the session is considered good and will be kept in the cache). If successful, SSL_shutdown() will return 0.</p> <p>If a unidirectional shutdown is enough (the underlying connection shall be closed anyway), this first successful call to SSL_shutdown() is sufficient.</p> <p>In order to complete the bidirectional shutdown handshake, the peer needs to send back a close_notify alert. The SSL_RECEIVED_SHUTDOWN flag will be set after receiving and processing it.</p> <p>The peer is still allowed to send data after receiving the close_notify event. When it is done sending data, it will send the close_notify alert. SSL_read() should be called until all data is received. SSL_read() will indicate the end of the peer data by returning <= 0 and SSL_get_error() returning SSL_ERROR_ZERO_RETURN.</p> <h2 id="Peer-closes-the-connection">Peer closes the connection</h2> <p>If the peer already sent the close_notify alert <b>and</b> it was already processed implicitly inside another function (<a href="../man3/SSL_read.html">SSL_read(3)</a>), the SSL_RECEIVED_SHUTDOWN flag is set. SSL_read() will return <= 0 in that case, and SSL_get_error() will return SSL_ERROR_ZERO_RETURN. SSL_shutdown() will send the close_notify alert, set the SSL_SENT_SHUTDOWN flag. If successful, SSL_shutdown() will return 1.</p> <p>Whether SSL_RECEIVED_SHUTDOWN is already set can be checked using the SSL_get_shutdown() (see also <a href="../man3/SSL_set_shutdown.html">SSL_set_shutdown(3)</a> call.</p> <h1 id="NOTES1">NOTES</h1> <p>The behaviour of SSL_shutdown() additionally depends on the underlying BIO. If the underlying BIO is <b>blocking</b>, SSL_shutdown() will only return once the handshake step has been finished or an error occurred.</p> <p>If the underlying BIO is <b>nonblocking</b>, SSL_shutdown() will also return when the underlying BIO could not satisfy the needs of SSL_shutdown() to continue the handshake. In this case a call to SSL_get_error() with the return value of SSL_shutdown() will yield <b>SSL_ERROR_WANT_READ</b> or <b>SSL_ERROR_WANT_WRITE</b>. The calling process then must repeat the call after taking appropriate action to satisfy the needs of SSL_shutdown(). The action depends on the underlying BIO. When using a nonblocking socket, nothing is to be done, but select() can be used to check for the required condition. When using a buffering BIO, like a BIO pair, data must be written into or retrieved out of the BIO before being able to continue.</p> <p>After SSL_shutdown() returned 0, it is possible to call SSL_shutdown() again to wait for the peer's close_notify alert. SSL_shutdown() will return 1 in that case. However, it is recommended to wait for it using SSL_read() instead.</p> <p>SSL_shutdown() can be modified to only set the connection to "shutdown" state but not actually send the close_notify alert messages, see <a href="../man3/SSL_CTX_set_quiet_shutdown.html">SSL_CTX_set_quiet_shutdown(3)</a>. When "quiet shutdown" is enabled, SSL_shutdown() will always succeed and return 1. Note that this is not standard compliant behaviour. It should only be done when the peer has a way to make sure all data has been received and doesn't wait for the close_notify alert message, otherwise an unexpected EOF will be reported.</p> <p>There are implementations that do not send the required close_notify alert. If there is a need to communicate with such an implementation, and it's clear that all data has been received, do not wait for the peer's close_notify alert. Waiting for the close_notify alert when the peer just closes the connection will result in an error being generated.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>The following return values can occur:</p> <dl> <dt id="pod0">0</dt> <dd> <p>The shutdown is not yet finished: the close_notify was sent but the peer did not send it back yet. Call SSL_read() to do a bidirectional shutdown.</p> <p>Unlike most other function, returning 0 does not indicate an error. <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a> should not get called, it may misleadingly indicate an error even though no error occurred.</p> </dd> <dt id="pod1">1</dt> <dd> <p>The shutdown was successfully completed.

If <i>b</i> is NULL the function does nothing and returns <i>next</i>. Otherwise it prepends <i>b</i>, which may be a single BIO or a chain of BIOs, to <i>next</i> (unless <i>next</i> is NULL).

Otherwise it makes a control call on <i>b</i> and returns the next BIO in the chain, or NULL if there is no next BIO. The removed BIO becomes a single BIO with no association with the original chain, it can thus be freed or be made part of a different chain.</p> <p>BIO_set_next() replaces the existing next BIO in a chain with the BIO pointed to by <i>next</i>.

These extensions are denoted by individual bits in capability vector returned by processor in EDX:ECX register pair after executing CPUID instruction with EAX=1 input value (see Intel Application Note #241618). This vector is copied to memory upon toolkit initialization and used to choose between different code paths to provide optimal performance across wide range of processors. For the moment of this writing following bits are significant:</p> <dl> <dt id="bit-4-denoting-presence-of-Time-Stamp-Counter">bit #4 denoting presence of Time-Stamp Counter.</dt> <dd> </dd> <dt id="bit-19-denoting-availability-of-CLFLUSH-instruction">bit #19 denoting availability of CLFLUSH instruction;</dt> <dd> </dd> <dt id="bit-20-reserved-by-Intel-is-used-to-choose-among-RC4-code-paths">bit #20, reserved by Intel, is used to choose among RC4 code paths;</dt> <dd> </dd> <dt id="bit-23-denoting-MMX-support">bit #23 denoting MMX support;</dt> <dd> </dd> <dt id="bit-24-FXSR-bit-denoting-availability-of-XMM-registers">bit #24, FXSR bit, denoting availability of XMM registers;</dt> <dd> </dd> <dt id="bit-25-denoting-SSE-support">bit #25 denoting SSE support;</dt> <dd> </dd> <dt id="bit-26-denoting-SSE2-support">bit #26 denoting SSE2 support;</dt> <dd> </dd> <dt id="bit-28-denoting-Hyperthreading-which-is-used-to-distinguish-cores-with-shared-cache">bit #28 denoting Hyperthreading, which is used to distinguish cores with shared cache;</dt> <dd> </dd> <dt id="bit-30-reserved-by-Intel-denotes-specifically-Intel-CPUs">bit #30, reserved by Intel, denotes specifically Intel CPUs;</dt> <dd> </dd> <dt id="bit-33-denoting-availability-of-PCLMULQDQ-instruction">bit #33 denoting availability of PCLMULQDQ instruction;</dt> <dd> </dd> <dt id="bit-41-denoting-SSSE3-Supplemental-SSE3-support">bit #41 denoting SSSE3, Supplemental SSE3, support;</dt> <dd> </dd> <dt id="bit-43-denoting-AMD-XOP-support-forced-to-zero-on-non-AMD-CPUs">bit #43 denoting AMD XOP support (forced to zero on non-AMD CPUs);</dt> <dd> </dd> <dt id="bit-54-denoting-availability-of-MOVBE-instruction">bit #54 denoting availability of MOVBE instruction;</dt> <dd> </dd> <dt id="bit-57-denoting-AES-NI-instruction-set-extension">bit #57 denoting AES-NI instruction set extension;</dt> <dd> </dd> <dt id="bit-58-XSAVE-bit-lack-of-which-in-combination-with-MOVBE-is-used-to-identify-Atom-Silvermont-core">bit #58, XSAVE bit, lack of which in combination with MOVBE is used to identify Atom Silvermont core;</dt> <dd> </dd> <dt id="bit-59-OSXSAVE-bit-denoting-availability-of-YMM-registers">bit #59, OSXSAVE bit, denoting availability of YMM registers;</dt> <dd> </dd> <dt id="bit-60-denoting-AVX-extension">bit #60 denoting AVX extension;</dt> <dd> </dd> <dt id="bit-62-denoting-availability-of-RDRAND-instruction">bit #62 denoting availability of RDRAND instruction;</dt> <dd> </dd> </dl> <p>For example, in 32-bit application context clearing bit #26 at run-time disables high-performance SSE2 code present in the crypto library, while clearing bit #24 disables SSE2 code operating on 128-bit XMM register bank. You might have to do the latter if target OpenSSL application is executed on SSE2 capable CPU, but under control of OS that does not enable XMM registers. Historically address of the capability vector copy was exposed to application through OPENSSL_ia32cap_loc(), but not anymore. Now the only way to affect the capability detection is to set OPENSSL_ia32cap environment variable prior target application start. To give a specific example, on Intel P4 processor 'env OPENSSL_ia32cap=0x16980010 apps/openssl', or better yet 'env OPENSSL_ia32cap=~0x1000000 apps/openssl' would achieve the desired effect. Alternatively you can reconfigure the toolkit with no-sse2 option and recompile.</p> <p>Less intuitive is clearing bit #28, or ~0x10000000 in the "environment variable" terms. The truth is that it's not copied from CPUID output verbatim, but is adjusted to reflect whether or not the data cache is actually shared between logical cores. This in turn affects the decision on whether or not expensive countermeasures against cache-timing attacks are applied, most notably in AES assembler module.</p> <p>The capability vector is further extended with EBX value returned by CPUID with EAX=7 and ECX=0 as input. Following bits are significant:</p> <dl> <dt id="bit-64-3-denoting-availability-of-BMI1-instructions-e.g.-ANDN">bit #64+3 denoting availability of BMI1 instructions, e.g. ANDN;</dt> <dd> </dd> <dt id="bit-64-5-denoting-availability-of-AVX2-instructions">bit #64+5 denoting availability of AVX2 instructions;</dt> <dd> </dd> <dt id="bit-64-8-denoting-availability-of-BMI2-instructions-e.g.-MULX-and-RORX">bit #64+8 denoting availability of BMI2 instructions, e.g. MULX and RORX;</dt> <dd> </dd> <dt id="bit-64-16-denoting-availability-of-AVX512F-extension">bit #64+16 denoting availability of AVX512F extension;</dt> <dd> </dd> <dt id="bit-64-18-denoting-availability-of-RDSEED-instruction">bit #64+18 denoting availability of RDSEED instruction;</dt> <dd> </dd> <dt id="bit-64-19-denoting-availability-of-ADCX-and-ADOX-instructions">bit #64+19 denoting availability of ADCX and ADOX instructions;</dt> <dd> </dd> <dt id="bit-64-21-denoting-availability-of-VPMADD52-LH-UQ-instructions-aka-AVX512IFMA-extension">bit #64+21 denoting availability of VPMADD52[LH]UQ instructions, aka AVX512IFMA extension;</dt> <dd> </dd> <dt id="bit-64-29-denoting-availability-of-SHA-extension">bit #64+29 denoting availability of SHA extension;</dt> <dd> </dd> <dt id="bit-64-30-denoting-availability-of-AVX512BW-extension">bit #64+30 denoting availability of AVX512BW extension;</dt> <dd> </dd> <dt id="bit-64-31-denoting-availability-of-AVX512VL-extension">bit #64+31 denoting availability of AVX512VL extension;</dt> <dd> </dd> <dt id="bit-64-41-denoting-availability-of-VAES-extension">bit #64+41 denoting availability of VAES extension;</dt> <dd> </dd> <dt id="bit-64-42-denoting-availability-of-VPCLMULQDQ-extension">bit #64+42 denoting availability of VPCLMULQDQ extension;</dt> <dd> </dd> </dl> <p>To control this extended capability word use ':' as delimiter when setting up OPENSSL_ia32cap environment variable. For example assigning ':~0x20' would disable AVX2 code paths, and ':0' - all post-AVX extensions.</p> <p>It should be noted that whether or not some of the most "fancy" extension code paths are actually assembled depends on current assembler version. Base minimum of AES-NI/PCLMULQDQ, SSSE3 and SHA extension code paths are always assembled. Apart from that, minimum assembler version requirements are summarized in below table:</p> <pre><code> Extension | GNU as | nasm | llvm ------------+--------+--------+-------- AVX | 2.19 | 2.09 | 3.0 AVX2 | 2.22 | 2.10 | 3.1 ADCX/ADOX | 2.23 | 2.10 | 3.3 AVX512 | 2.25 | 2.11.8 | see NOTES AVX512IFMA | 2.26 | 2.11.8 | see NOTES VAES | 2.30 | 2.13.3 |</code></pre> <h1 id="NOTES">NOTES</h1> <p>Even though AVX512 support was implemented in llvm 3.6, compilation of assembly modules apparently requires explicit -march flag. But then compiler generates processor-specific code, which in turn contradicts the mere idea of run-time switch execution facilitated by the variable in question. Till the limitation is lifted, it's possible to work around the problem by making build procedure use following script:</p> <pre><code> #!/bin/sh exec clang -no-integrated-as "$@"</code></pre> <p>instead of real clang. In which case it doesn't matter which clang version is used, as it is GNU assembler version that will be checked.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>Not available.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2004-2020 The OpenSSL Project Authors.

This can be used to set either defaults or values which cannot be overridden. For example if an application calls:</p> <pre><code> SSL_CONF_cmd(ctx, "Protocol", "-SSLv3"); SSL_CONF_cmd(ctx, userparam, uservalue);</code></pre> <p>it will disable SSLv3 support by default but the user can override it. If however the call sequence is:</p> <pre><code> SSL_CONF_cmd(ctx, userparam, uservalue); SSL_CONF_cmd(ctx, "Protocol", "-SSLv3");</code></pre> <p>SSLv3 is <b>always</b> disabled and attempt to override this by the user are ignored.</p> <p>By checking the return code of SSL_CONF_cmd() it is possible to query if a given <b>cmd</b> is recognised, this is useful if SSL_CONF_cmd() values are mixed with additional application specific operations.</p> <p>For example an application might call SSL_CONF_cmd() and if it returns -2 (unrecognised command) continue with processing of application specific commands.</p> <p>Applications can also use SSL_CONF_cmd() to process command lines though the utility function SSL_CONF_cmd_argv() is normally used instead. One way to do this is to set the prefix to an appropriate value using SSL_CONF_CTX_set1_prefix(), pass the current argument to <b>cmd</b> and the following argument to <b>value</b> (which may be NULL).</p> <p>In this case if the return value is positive then it is used to skip that number of arguments as they have been processed by SSL_CONF_cmd(). If -2 is returned then <b>cmd</b> is not recognised and application specific arguments can be checked instead. If -3 is returned a required argument is missing and an error is indicated. If 0 is returned some other error occurred and this can be reported back to the user.</p> <p>The function SSL_CONF_cmd_value_type() can be used by applications to check for the existence of a command or to perform additional syntax checking or translation of the command value. For example if the return value is <b>SSL_CONF_TYPE_FILE</b> an application could translate a relative pathname to an absolute pathname.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_CONF_cmd() returns 1 if the value of <b>cmd</b> is recognised and <b>value</b> is <b>NOT</b> used and 2 if both <b>cmd</b> and <b>value</b> are used. In other words it returns the number of arguments processed. This is useful when processing command lines.</p> <p>A return value of -2 means <b>cmd</b> is not recognised.</p> <p>A return value of -3 means <b>cmd</b> is recognised and the command requires a value but <b>value</b> is NULL.</p> <p>A return code of 0 indicates that both <b>cmd</b> and <b>value</b> are valid but an error occurred attempting to perform the operation: for example due to an error in the syntax of <b>value</b> in this case the error queue may provide additional information.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Set supported signature algorithms:</p> <pre><code> SSL_CONF_cmd(ctx, "SignatureAlgorithms", "ECDSA+SHA256:RSA+SHA256:DSA+SHA256");</code></pre> <p>There are various ways to select the supported protocols.</p> <p>This set the minimum protocol version to TLSv1, and so disables SSLv3. This is the recommended way to disable protocols.</p> <pre><code> SSL_CONF_cmd(ctx, "MinProtocol", "TLSv1");</code></pre> <p>The following also disables SSLv3:</p> <pre><code> SSL_CONF_cmd(ctx, "Protocol", "-SSLv3");</code></pre> <p>The following will first enable all protocols, and then disable SSLv3.

It supports non blocking I/O. Content is processed and streamed on the fly and not all held in memory at once: so it is possible to encode very large structures. After all content has been written through the chain BIO_flush() must be called to finalise the structure.</p> <p>The <b>CMS_STREAM</b> flag must be included in the corresponding <b>flags</b> parameter of the <b>cms</b> creation function.</p> <p>If an application wishes to write additional data to <b>out</b> BIOs should be removed from the chain using BIO_pop() and freed with BIO_free() until <b>out</b> is reached. If no additional data needs to be written BIO_free_all() can be called to free up the whole chain.</p> <p>Any content written through the filter is used verbatim: no canonical translation is performed.</p> <p>It is possible to chain multiple BIOs to, for example, create a triple wrapped signed, enveloped, signed structure. In this case it is the applications responsibility to set the inner content type of any outer CMS_ContentInfo structures.</p> <p>Large numbers of small writes through the chain should be avoided as this will produce an output consisting of lots of OCTET STRING structures.

This is being done by calling <a href="../man3/SSL_set_connect_state.html">SSL_set_connect_state(3)</a> or SSL_set_accept_state() before the first call to a write function.</p> <p>If the underlying BIO is <b>blocking</b>, the write functions will only return, once the write operation has been finished or an error occurred.</p> <p>If the underlying BIO is <b>nonblocking</b> the write functions will also return when the underlying BIO could not satisfy the needs of the function to continue the operation. In this case a call to <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a> with the return value of the write function will yield <b>SSL_ERROR_WANT_READ</b> or <b>SSL_ERROR_WANT_WRITE</b>. As at any time a re-negotiation is possible, a call to a write function can also cause read operations! The calling process then must repeat the call after taking appropriate action to satisfy the needs of the write function. The action depends on the underlying BIO. When using a nonblocking socket, nothing is to be done, but select() can be used to check for the required condition. When using a buffering BIO, like a BIO pair, data must be written into or retrieved out of the BIO before being able to continue.</p> <p>The write functions will only return with success when the complete contents of <b>buf</b> of length <b>num</b> has been written. This default behaviour can be changed with the SSL_MODE_ENABLE_PARTIAL_WRITE option of <a href="../man3/SSL_CTX_set_mode.html">SSL_CTX_set_mode(3)</a>. When this flag is set the write functions will also return with success when a partial write has been successfully completed. In this case the write function operation is considered completed. The bytes are sent and a new write call with a new buffer (with the already sent bytes removed) must be started. A partial write is performed with the size of a message block, which is 16kB.</p> <h1 id="WARNINGS">WARNINGS</h1> <p>When a write function call has to be repeated because <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a> returned <b>SSL_ERROR_WANT_READ</b> or <b>SSL_ERROR_WANT_WRITE</b>, it must be repeated with the same arguments. The data that was passed might have been partially processed. When <b>SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER</b> was set using <a href="../man3/SSL_CTX_set_mode.html">SSL_CTX_set_mode(3)</a> the pointer can be different, but the data and length should still be the same.</p> <p>You should not call SSL_write() with num=0, it will return an error. SSL_write_ex() can be called with num=0, but will not send application data to the peer.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>SSL_write_ex() will return 1 for success or 0 for failure. Success means that all requested application data bytes have been written to the SSL connection or, if SSL_MODE_ENABLE_PARTIAL_WRITE is in use, at least 1 application data byte has been written to the SSL connection. Failure means that not all the requested bytes have been written yet (if SSL_MODE_ENABLE_PARTIAL_WRITE is not in use) or no bytes could be written to the SSL connection (if SSL_MODE_ENABLE_PARTIAL_WRITE is in use). Failures can be retryable (e.g. the network write buffer has temporarily filled up) or non-retryable (e.g. a fatal network error). In the event of a failure call <a href="../man3/SSL_get_error.html">SSL_get_error(3)</a> to find out the reason which indicates whether the call is retryable or not.</p> <p>For SSL_write() the following return values can occur:</p> <dl> <dt id="pod0">> 0</dt> <dd> <p>The write operation was successful, the return value is the number of bytes actually written to the TLS/SSL connection.</p> </dd> <dt id="pod-0"><= 0</dt> <dd> <p>The write operation was not successful, because either the connection was closed, an error occurred or action must be taken by the calling process. Call SSL_get_error() with the return value <b>ret</b> to find out the reason.</p> <p>Old documentation indicated a difference between 0 and -1, and that -1 was retryable.

Any or all of these parameters can be <b>NULL</b>, see <b>NOTES</b> below.</p> <p>The data to be signed is read from BIO <b>data</b>.</p> <p><b>flags</b> is an optional set of flags.</p> <h1 id="NOTES">NOTES</h1> <p>Any of the following flags (ored together) can be passed in the <b>flags</b> parameter.</p> <p>Many S/MIME clients expect the signed content to include valid MIME headers. If the <b>CMS_TEXT</b> flag is set MIME headers for type <b>text/plain</b> are prepended to the data.</p> <p>If <b>CMS_NOCERTS</b> is set the signer's certificate will not be included in the CMS_ContentInfo structure, the signer's certificate must still be supplied in the <b>signcert</b> parameter though. This can reduce the size of the signature if the signers certificate can be obtained by other means: for example a previously signed message.</p> <p>The data being signed is included in the CMS_ContentInfo structure, unless <b>CMS_DETACHED</b> is set in which case it is omitted. This is used for CMS_ContentInfo detached signatures which are used in S/MIME plaintext signed messages for example.</p> <p>Normally the supplied content is translated into MIME canonical format (as required by the S/MIME specifications) if <b>CMS_BINARY</b> is set no translation occurs. This option should be used if the supplied data is in binary format otherwise the translation will corrupt it.</p> <p>The SignedData structure includes several CMS signedAttributes including the signing time, the CMS content type and the supported list of ciphers in an SMIMECapabilities attribute. If <b>CMS_NOATTR</b> is set then no signedAttributes will be used. If <b>CMS_NOSMIMECAP</b> is set then just the SMIMECapabilities are omitted.</p> <p>If present the SMIMECapabilities attribute indicates support for the following algorithms in preference order: 256 bit AES, Gost R3411-94, Gost 28147-89, 192 bit AES, 128 bit AES, triple DES, 128 bit RC2, 64 bit RC2, DES and 40 bit RC2. If any of these algorithms is not available then it will not be included: for example the GOST algorithms will not be included if the GOST ENGINE is not loaded.</p> <p>OpenSSL will by default identify signing certificates using issuer name and serial number. If <b>CMS_USE_KEYID</b> is set it will use the subject key identifier value instead. An error occurs if the signing certificate does not have a subject key identifier extension.</p> <p>If the flags <b>CMS_STREAM</b> is set then the returned <b>CMS_ContentInfo</b> structure is just initialized ready to perform the signing operation. The signing is however <b>not</b> performed and the data to be signed is not read from the <b>data</b> parameter. Signing is deferred until after the data has been written. In this way data can be signed in a single pass.</p> <p>If the <b>CMS_PARTIAL</b> flag is set a partial <b>CMS_ContentInfo</b> structure is output to which additional signers and capabilities can be added before finalization.</p> <p>If the flag <b>CMS_STREAM</b> is set the returned <b>CMS_ContentInfo</b> structure is <b>not</b> complete and outputting its contents via a function that does not properly finalize the <b>CMS_ContentInfo</b> structure will give unpredictable results.</p> <p>Several functions including SMIME_write_CMS(), i2d_CMS_bio_stream(), PEM_write_bio_CMS_stream() finalize the structure. Alternatively finalization can be performed by obtaining the streaming ASN1 <b>BIO</b> directly using BIO_new_CMS().</p> <p>If a signer is specified it will use the default digest for the signing algorithm. This is <b>SHA1</b> for both RSA and DSA keys.</p> <p>If <b>signcert</b> and <b>pkey</b> are NULL then a certificates only CMS structure is output.</p> <p>The function CMS_sign() is a basic CMS signing function whose output will be suitable for many purposes. For finer control of the output format the <b>certs</b>, <b>signcert</b> and <b>pkey</b> parameters can all be <b>NULL</b> and the <b>CMS_PARTIAL</b> flag set. Then one or more signers can be added using the function CMS_add1_signer(), non default digests can be used and custom attributes added. CMS_final() must then be called to finalize the structure if streaming is not enabled.</p> <h1 id="BUGS">BUGS</h1> <p>Some attributes such as counter signatures are not supported.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>CMS_sign() returns either a valid CMS_ContentInfo structure or NULL if an error occurred.

Additionally some resources are allocated on a per thread basis (if the application is multi-threaded), and these resources must be freed prior to the thread closing.</p> <p>As of version 1.1.0 OpenSSL will automatically allocate all resources that it needs so no explicit initialisation is required. Similarly it will also automatically deinitialise as required.</p> <p>However, there may be situations when explicit initialisation is desirable or needed, for example when some nondefault initialisation is required. The function OPENSSL_init_ssl() can be used for this purpose. Calling this function will explicitly initialise BOTH libcrypto and libssl. To explicitly initialise ONLY libcrypto see the <a href="../man3/OPENSSL_init_crypto.html">OPENSSL_init_crypto(3)</a> function.</p> <p>Numerous internal OpenSSL functions call OPENSSL_init_ssl(). Therefore, in order to perform nondefault initialisation, OPENSSL_init_ssl() MUST be called by application code prior to any other OpenSSL function calls.</p> <p>The <b>opts</b> parameter specifies which aspects of libssl and libcrypto should be initialised. Valid options for libcrypto are described on the <a href="../man3/OPENSSL_init_crypto.html">OPENSSL_init_crypto(3)</a> page. In addition to any libcrypto specific option the following libssl options can also be used:</p> <dl> <dt id="OPENSSL_INIT_NO_LOAD_SSL_STRINGS">OPENSSL_INIT_NO_LOAD_SSL_STRINGS</dt> <dd> <p>Suppress automatic loading of the libssl error strings.

Session tickets, defined in RFC5077 provide an enhanced session resumption capability where the server implementation is not required to maintain per session state. It only applies to TLS and there is no SSLv3 implementation.</p> <p>The callback function <i>cb</i> will be called for every client instigated TLS session when session ticket extension is presented in the TLS hello message. It is the responsibility of this function to create or retrieve the cryptographic parameters and to maintain their state.</p> <p>The OpenSSL library uses your callback function to help implement a common TLS ticket construction state according to RFC5077 Section 4 such that per session state is unnecessary and a small set of cryptographic variables needs to be maintained by the callback function implementation.</p> <p>In order to reuse a session, a TLS client must send the a session ticket extension to the server. The client can only send exactly one session ticket. The server, through the callback function, either agrees to reuse the session ticket information or it starts a full TLS handshake to create a new session ticket.</p> <p>Before the callback function is started <i>ctx</i> and <i>hctx</i> have been initialised with <a href="../man3/EVP_CIPHER_CTX_reset.html">EVP_CIPHER_CTX_reset(3)</a> and <a href="../man3/HMAC_CTX_reset.html">HMAC_CTX_reset(3)</a> respectively.</p> <p>For new sessions tickets, when the client doesn't present a session ticket, or an attempted retrieval of the ticket failed, or a renew option was indicated, the callback function will be called with <i>enc</i> equal to 1. The OpenSSL library expects that the function will set an arbitrary <i>name</i>, initialize <i>iv</i>, and set the cipher context <i>ctx</i> and the hash context <i>hctx</i>.</p> <p>The <i>name</i> is 16 characters long and is used as a key identifier.</p> <p>The <i>iv</i> length is the length of the IV of the corresponding cipher. The maximum IV length is <b>EVP_MAX_IV_LENGTH</b> bytes defined in <b>evp.h</b>.</p> <p>The initialization vector <i>iv</i> should be a random value. The cipher context <i>ctx</i> should use the initialisation vector <i>iv</i>. The cipher context can be set using <a href="../man3/EVP_EncryptInit_ex.html">EVP_EncryptInit_ex(3)</a>. The hmac context can be set using <a href="../man3/HMAC_Init_ex.html">HMAC_Init_ex(3)</a>.</p> <p>When the client presents a session ticket, the callback function with be called with <i>enc</i> set to 0 indicating that the <i>cb</i> function should retrieve a set of parameters. In this case <i>name</i> and <i>iv</i> have already been parsed out of the session ticket. The OpenSSL library expects that the <i>name</i> will be used to retrieve a cryptographic parameters and that the cryptographic context <i>ctx</i> will be set with the retrieved parameters and the initialization vector <i>iv</i>. using a function like <a href="../man3/EVP_DecryptInit_ex.html">EVP_DecryptInit_ex(3)</a>. The <i>hctx</i> needs to be set using <a href="../man3/HMAC_Init_ex.html">HMAC_Init_ex(3)</a>.</p> <p>If the <i>name</i> is still valid but a renewal of the ticket is required the callback function should return 2. The library will call the callback again with an argument of enc equal to 1 to set the new ticket.</p> <p>The return value of the <i>cb</i> function is used by OpenSSL to determine what further processing will occur. The following return values have meaning:</p> <dl> <dt id="pod2">2</dt> <dd> <p>This indicates that the <i>ctx</i> and <i>hctx</i> have been set and the session can continue on those parameters. Additionally it indicates that the session ticket is in a renewal period and should be replaced. The OpenSSL library will call <i>cb</i> again with an enc argument of 1 to set the new ticket (see RFC5077 3.3 paragraph 2).</p> </dd> <dt id="pod1">1</dt> <dd> <p>This indicates that the <i>ctx</i> and <i>hctx</i> have been set and the session can continue on those parameters.</p> </dd> <dt id="pod0">0</dt> <dd> <p>This indicates that it was not possible to set/retrieve a session ticket and the SSL/TLS session will continue by negotiating a set of cryptographic parameters or using the alternate SSL/TLS resumption mechanism, session ids.</p> <p>If called with enc equal to 0 the library will call the <i>cb</i> again to get a new set of parameters.</p> </dd> <dt id="less-than-0">less than 0</dt> <dd> <p>This indicates an error.</p> </dd> </dl> <h1 id="NOTES">NOTES</h1> <p>Session resumption shortcuts the TLS so that the client certificate negotiation don't occur. It makes up for this by storing client certificate an all other negotiated state information encrypted within the ticket. In a resumed session the applications will have all this state information available exactly as if a full negotiation had occurred.</p> <p>If an attacker can obtain the key used to encrypt a session ticket, they can obtain the master secret for any ticket using that key and decrypt any traffic using that session: even if the cipher suite supports forward secrecy. As a result applications may wish to use multiple keys and avoid using long term keys stored in files.</p> <p>Applications can use longer keys to maintain a consistent level of security. For example if a cipher suite uses 256 bit ciphers but only a 128 bit ticket key the overall security is only 128 bits because breaking the ticket key will enable an attacker to obtain the session keys.</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>Returns 1 to indicate the callback function was set and 0 otherwise.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Reference Implementation:</p> <pre><code> SSL_CTX_set_tlsext_ticket_key_cb(SSL, ssl_tlsext_ticket_key_cb); ... static int ssl_tlsext_ticket_key_cb(SSL *s, unsigned char key_name[16], unsigned char *iv, EVP_CIPHER_CTX *ctx, HMAC_CTX *hctx, int enc) { your_type_t *key; /* something that you need to implement */ if (enc) { /* create new session */ if (RAND_bytes(iv, EVP_MAX_IV_LENGTH) <= 0) return -1; /* insufficient random */ key = currentkey(); /* something that you need to implement */ if (key == NULL) { /* current key doesn't exist or isn't valid */ key = createkey(); /* * Something that you need to implement. * createkey needs to initialise a name, * an aes_key, a hmac_key and optionally * an expire time. */ if (key == NULL) /* key couldn't be created */ return 0; } memcpy(key_name, key->name, 16); EVP_EncryptInit_ex(&ctx, EVP_aes_256_cbc(), NULL, key->aes_key, iv); HMAC_Init_ex(&hctx, key->hmac_key, 32, EVP_sha256(), NULL); return 1; } else { /* retrieve session */ time_t t = time(NULL); key = findkey(key_name); /* something that you need to implement */ if (key == NULL || key->expire < t) return 0; HMAC_Init_ex(&hctx, key->hmac_key, 32, EVP_sha256(), NULL); EVP_DecryptInit_ex(&ctx, EVP_aes_256_cbc(), NULL, key->aes_key, iv); if (key->expire < t - RENEW_TIME) { /* RENEW_TIME: implement */ /* * return 2 - This session will get a new ticket even though the * current one is still valid. */ return 2; } return 1; } }</code></pre> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man7/ssl.html">ssl(7)</a>, <a href="../man3/SSL_set_session.html">SSL_set_session(3)</a>, <a href="../man3/SSL_session_reused.html">SSL_session_reused(3)</a>, <a href="../man3/SSL_CTX_add_session.html">SSL_CTX_add_session(3)</a>, <a href="../man3/SSL_CTX_sess_number.html">SSL_CTX_sess_number(3)</a>, <a href="../man3/SSL_CTX_sess_set_get_cb.html">SSL_CTX_sess_set_get_cb(3)</a>, <a href="../man3/SSL_CTX_set_session_id_context.html">SSL_CTX_set_session_id_context(3)</a>,</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2014-2021 The OpenSSL Project Authors.

It is used for the OpenSSL master configuration file <b>openssl.cnf</b> and in a few other places like <b>SPKAC</b> files and certificate extension files for the <b>x509</b> utility. OpenSSL applications can also use the CONF library for their own purposes.</p> <p>A configuration file is divided into a number of sections. Each section starts with a line <b>[ section_name ]</b> and ends when a new section is started or end of file is reached. A section name can consist of alphanumeric characters and underscores.</p> <p>The first section of a configuration file is special and is referred to as the <b>default</b> section. This section is usually unnamed and spans from the start of file until the first named section. When a name is being looked up it is first looked up in a named section (if any) and then the default section.</p> <p>The environment is mapped onto a section called <b>ENV</b>.</p> <p>Comments can be included by preceding them with the <b>#</b> character</p> <p>Other files can be included using the <b>.include</b> directive followed by a path. If the path points to a directory all files with names ending with <b>.cnf</b> or <b>.conf</b> are included from the directory. Recursive inclusion of directories from files in such directory is not supported. That means the files in the included directory can also contain <b>.include</b> directives but only inclusion of regular files is supported there. The inclusion of directories is not supported on systems without POSIX IO support.</p> <p>It is strongly recommended to use absolute paths with the <b>.include</b> directive. Relative paths are evaluated based on the application current working directory so unless the configuration file containing the <b>.include</b> directive is application specific the inclusion will not work as expected.</p> <p>There can be optional <b>=</b> character and whitespace characters between <b>.include</b> directive and the path which can be useful in cases the configuration file needs to be loaded by old OpenSSL versions which do not support the <b>.include</b> syntax. They would bail out with error if the <b>=</b> character is not present but with it they just ignore the include.</p> <p>Each section in a configuration file consists of a number of name and value pairs of the form <b>name=value</b></p> <p>The <b>name</b> string can contain any alphanumeric characters as well as a few punctuation symbols such as <b>.</b> <b>,</b> <b>;</b> and <b>_</b>.</p> <p>The <b>value</b> string consists of the string following the <b>=</b> character until end of line with any leading and trailing white space removed.</p> <p>The value string undergoes variable expansion. This can be done by including the form <b>$var</b> or <b>${var}</b>: this will substitute the value of the named variable in the current section. It is also possible to substitute a value from another section using the syntax <b>$section::name</b> or <b>${section::name}</b>. By using the form <b>$ENV::name</b> environment variables can be substituted. It is also possible to assign values to environment variables by using the name <b>ENV::name</b>, this will work if the program looks up environment variables using the <b>CONF</b> library instead of calling getenv() directly. The value string must not exceed 64k in length after variable expansion. Otherwise an error will occur.</p> <p>It is possible to escape certain characters by using any kind of quote or the <b>\</b> character. By making the last character of a line a <b>\</b> a <b>value</b> string can be spread across multiple lines. In addition the sequences <b>\n</b>, <b>\r</b>, <b>\b</b> and <b>\t</b> are recognized.</p> <p>All expansion and escape rules as described above that apply to <b>value</b> also apply to the path of the <b>.include</b> directive.</p> <h1 id="OPENSSL-LIBRARY-CONFIGURATION">OPENSSL LIBRARY CONFIGURATION</h1> <p>Applications can automatically configure certain aspects of OpenSSL using the master OpenSSL configuration file, or optionally an alternative configuration file. The <b>openssl</b> utility includes this functionality: any sub command uses the master OpenSSL configuration file unless an option is used in the sub command to use an alternative configuration file.</p> <p>To enable library configuration the default section needs to contain an appropriate line which points to the main configuration section. The default name is <b>openssl_conf</b> which is used by the <b>openssl</b> utility. Other applications may use an alternative name such as <b>myapplication_conf</b>. All library configuration lines appear in the default section at the start of the configuration file.</p> <p>The configuration section should consist of a set of name value pairs which contain specific module configuration information. The <b>name</b> represents the name of the <i>configuration module</i>. The meaning of the <b>value</b> is module specific: it may, for example, represent a further configuration section containing configuration module specific information. E.g.:</p> <pre><code> # This must be in the default section openssl_conf = openssl_init [openssl_init] oid_section = new_oids engines = engine_section [new_oids] ... new oids here ... [engine_section] ... engine stuff here ...</code></pre> <p>The features of each configuration module are described below.</p> <h2 id="ASN1-Object-Configuration-Module">ASN1 Object Configuration Module</h2> <p>This module has the name <b>oid_section</b>. The value of this variable points to a section containing name value pairs of OIDs: the name is the OID short and long name, the value is the numerical form of the OID. Although some of the <b>openssl</b> utility sub commands already have their own ASN1 OBJECT section functionality not all do. By using the ASN1 OBJECT configuration module <b>all</b> the <b>openssl</b> utility sub commands can see the new objects as well as any compliant applications. For example:</p> <pre><code> [new_oids] some_new_oid = 1.2.3.4 some_other_oid = 1.2.3.5</code></pre> <p>It is also possible to set the value to the long name followed by a comma and the numerical OID form. For example:</p> <pre><code> shortName = some object long name, 1.2.3.4</code></pre> <h2 id="Engine-Configuration-Module">Engine Configuration Module</h2> <p>This ENGINE configuration module has the name <b>engines</b>. The value of this variable points to a section containing further ENGINE configuration information.</p> <p>The section pointed to by <b>engines</b> is a table of engine names (though see <b>engine_id</b> below) and further sections containing configuration information specific to each ENGINE.</p> <p>Each ENGINE specific section is used to set default algorithms, load dynamic, perform initialization and send ctrls. The actual operation performed depends on the <i>command</i> name which is the name of the name value pair. The currently supported commands are listed below.</p> <p>For example:</p> <pre><code> [engine_section] # Configure ENGINE named "foo" foo = foo_section # Configure ENGINE named "bar" bar = bar_section [foo_section] ... foo ENGINE specific commands ... [bar_section] ... "bar" ENGINE specific commands ...</code></pre> <p>The command <b>engine_id</b> is used to give the ENGINE name. If used this command must be first. For example:</p> <pre><code> [engine_section] # This would normally handle an ENGINE named "foo" foo = foo_section [foo_section] # Override default name and use "myfoo" instead. engine_id = myfoo</code></pre> <p>The command <b>dynamic_path</b> loads and adds an ENGINE from the given path. It is equivalent to sending the ctrls <b>SO_PATH</b> with the path argument followed by <b>LIST_ADD</b> with value 2 and <b>LOAD</b> to the dynamic ENGINE. If this is not the required behaviour then alternative ctrls can be sent directly to the dynamic ENGINE using ctrl commands.</p> <p>The command <b>init</b> determines whether to initialize the ENGINE. If the value is <b>0</b> the ENGINE will not be initialized, if <b>1</b> and attempt it made to initialized the ENGINE immediately. If the <b>init</b> command is not present then an attempt will be made to initialize the ENGINE after all commands in its section have been processed.</p> <p>The command <b>default_algorithms</b> sets the default algorithms an ENGINE will supply using the functions ENGINE_set_default_string().</p> <p>If the name matches none of the above command names it is assumed to be a ctrl command which is sent to the ENGINE. The value of the command is the argument to the ctrl command. If the value is the string <b>EMPTY</b> then no value is sent to the command.</p> <p>For example:</p> <pre><code> [engine_section] # Configure ENGINE named "foo" foo = foo_section [foo_section] # Load engine from DSO dynamic_path = /some/path/fooengine.so # A foo specific ctrl. some_ctrl = some_value # Another ctrl that doesn't take a value. other_ctrl = EMPTY # Supply all default algorithms default_algorithms = ALL</code></pre> <h2 id="EVP-Configuration-Module">EVP Configuration Module</h2> <p>This modules has the name <b>alg_section</b> which points to a section containing algorithm commands.</p> <p>Currently the only algorithm command supported is <b>fips_mode</b> whose value can only be the boolean string <b>off</b>. If <b>fips_mode</b> is set to <b>on</b>, an error occurs as this library version is not FIPS capable.</p> <h2 id="SSL-Configuration-Module">SSL Configuration Module</h2> <p>This module has the name <b>ssl_conf</b> which points to a section containing SSL configurations.</p> <p>Each line in the SSL configuration section contains the name of the configuration and the section containing it.</p> <p>Each configuration section consists of command value pairs for <b>SSL_CONF</b>. Each pair will be passed to a <b>SSL_CTX</b> or <b>SSL</b> structure if it calls SSL_CTX_config() or SSL_config() with the appropriate configuration name.</p> <p>Note: any characters before an initial dot in the configuration section are ignored so the same command can be used multiple times.</p> <p>For example:</p> <pre><code> ssl_conf = ssl_sect [ssl_sect] server = server_section [server_section] RSA.Certificate = server-rsa.pem ECDSA.Certificate = server-ecdsa.pem Ciphers = ALL:!RC4</code></pre> <p>The system default configuration with name <b>system_default</b> if present will be applied during any creation of the <b>SSL_CTX</b> structure.</p> <p>Example of a configuration with the system default:</p> <pre><code> ssl_conf = ssl_sect [ssl_sect] system_default = system_default_sect [system_default_sect] MinProtocol = TLSv1.2 MinProtocol = DTLSv1.2</code></pre> <h1 id="NOTES">NOTES</h1> <p>If a configuration file attempts to expand a variable that doesn't exist then an error is flagged and the file will not load. This can happen if an attempt is made to expand an environment variable that doesn't exist. For example in a previous version of OpenSSL the default OpenSSL master configuration file used the value of <b>HOME</b> which may not be defined on non Unix systems and would cause an error.</p> <p>This can be worked around by including a <b>default</b> section to provide a default value: then if the environment lookup fails the default value will be used instead. For this to work properly the default value must be defined earlier in the configuration file than the expansion. See the <b>EXAMPLES</b> section for an example of how to do this.</p> <p>If the same variable exists in the same section then all but the last value will be silently ignored. In certain circumstances such as with DNs the same field may occur multiple times. This is usually worked around by ignoring any characters before an initial <b>.</b> e.g.</p> <pre><code> 1.OU="My first OU" 2.OU="My Second OU"</code></pre> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Here is a sample configuration file using some of the features mentioned above.</p> <pre><code> # This is the default section. HOME=/temp RANDFILE= ${ENV::HOME}/.rnd configdir=$ENV::HOME/config [ section_one ] # We are now in section one. # Quotes permit leading and trailing whitespace any = " any variable name " other = A string that can \ cover several lines \ by including \\ characters message = Hello World\n [ section_two ] greeting = $section_one::message</code></pre> <p>This next example shows how to expand environment variables safely.</p> <p>Suppose you want a variable called <b>tmpfile</b> to refer to a temporary filename. The directory it is placed in can determined by the <b>TEMP</b> or <b>TMP</b> environment variables but they may not be set to any value at all. If you just include the environment variable names and the variable doesn't exist then this will cause an error when an attempt is made to load the configuration file. By making use of the default section both values can be looked up with <b>TEMP</b> taking priority and <b>/tmp</b> used if neither is defined:</p> <pre><code> TMP=/tmp # The above value is used if TMP isn't in the environment TEMP=$ENV::TMP # The above value is used if TEMP isn't in the environment tmpfile=${ENV::TEMP}/tmp.filename</code></pre> <p>Simple OpenSSL library configuration example to enter FIPS mode:</p> <pre><code> # Default appname: should match "appname" parameter (if any) # supplied to CONF_modules_load_file et al. openssl_conf = openssl_conf_section [openssl_conf_section] # Configuration module list alg_section = evp_sect [evp_sect] # Set to "yes" to enter FIPS mode if supported fips_mode = yes</code></pre> <p>Note: in the above example you will get an error in non FIPS capable versions of OpenSSL.</p> <p>Simple OpenSSL library configuration to make TLS 1.2 and DTLS 1.2 the system-default minimum TLS and DTLS versions, respectively:</p> <pre><code> # Toplevel section for openssl (including libssl) openssl_conf = default_conf_section [default_conf_section] # We only specify configuration for the "ssl module" ssl_conf = ssl_section [ssl_section] system_default = system_default_section [system_default_section] MinProtocol = TLSv1.2 MinProtocol = DTLSv1.2</code></pre> <p>The minimum TLS protocol is applied to <b>SSL_CTX</b> objects that are TLS-based, and the minimum DTLS protocol to those are DTLS-based. The same applies also to maximum versions set with <b>MaxProtocol</b>.</p> <p>More complex OpenSSL library configuration. Add OID and don't enter FIPS mode:</p> <pre><code> # Default appname: should match "appname" parameter (if any) # supplied to CONF_modules_load_file et al. openssl_conf = openssl_conf_section [openssl_conf_section] # Configuration module list alg_section = evp_sect oid_section = new_oids [evp_sect] # This will have no effect as FIPS mode is off by default. # Set to "yes" to enter FIPS mode, if supported fips_mode = no [new_oids] # New OID, just short name newoid1 = 1.2.3.4.1 # New OID shortname and long name newoid2 = New OID 2 long name, 1.2.3.4.2</code></pre> <p>The above examples can be used with any application supporting library configuration if "openssl_conf" is modified to match the appropriate "appname".</p> <p>For example if the second sample file above is saved to "example.cnf" then the command line:</p> <pre><code> OPENSSL_CONF=example.cnf openssl asn1parse -genstr OID:1.2.3.4.1</code></pre> <p>will output:</p> <pre><code> 0:d=0 hl=2 l= 4 prim: OBJECT :newoid1</code></pre> <p>showing that the OID "newoid1" has been added as "1.2.3.4.1".</p> <h1 id="ENVIRONMENT">ENVIRONMENT</h1> <dl> <dt id="OPENSSL_CONF"><b>OPENSSL_CONF</b></dt> <dd> <p>The path to the config file.

Each line of the extension section takes the form:</p> <pre><code> extension_name=[critical,] extension_options</code></pre> <p>If <b>critical</b> is present then the extension will be critical.</p> <p>The format of <b>extension_options</b> depends on the value of <b>extension_name</b>.</p> <p>There are four main types of extension: <i>string</i> extensions, <i>multi-valued</i> extensions, <i>raw</i> and <i>arbitrary</i> extensions.</p> <p>String extensions simply have a string which contains either the value itself or how it is obtained.</p> <p>For example:</p> <pre><code> nsComment="This is a Comment"</code></pre> <p>Multi-valued extensions have a short form and a long form. The short form is a list of names and values:</p> <pre><code> basicConstraints=critical,CA:true,pathlen:1</code></pre> <p>The long form allows the values to be placed in a separate section:</p> <pre><code> basicConstraints=critical,@bs_section [bs_section] CA=true pathlen=1</code></pre> <p>Both forms are equivalent.</p> <p>The syntax of raw extensions is governed by the extension code: it can for example contain data in multiple sections. The correct syntax to use is defined by the extension code itself: check out the certificate policies extension for an example.</p> <p>If an extension type is unsupported then the <i>arbitrary</i> extension syntax must be used, see the <a href="#ARBITRARY-EXTENSIONS">ARBITRARY EXTENSIONS</a> section for more details.</p> <h1 id="STANDARD-EXTENSIONS">STANDARD EXTENSIONS</h1> <p>The following sections describe each supported extension in detail.</p> <h2 id="Basic-Constraints">Basic Constraints.</h2> <p>This is a multi valued extension which indicates whether a certificate is a CA certificate. The first (mandatory) name is <b>CA</b> followed by <b>TRUE</b> or <b>FALSE</b>. If <b>CA</b> is <b>TRUE</b> then an optional <b>pathlen</b> name followed by a nonnegative value can be included.</p> <p>For example:</p> <pre><code> basicConstraints=CA:TRUE basicConstraints=CA:FALSE basicConstraints=critical,CA:TRUE, pathlen:0</code></pre> <p>A CA certificate <b>must</b> include the basicConstraints value with the CA field set to TRUE. An end user certificate must either set CA to FALSE or exclude the extension entirely. Some software may require the inclusion of basicConstraints with CA set to FALSE for end entity certificates.</p> <p>The pathlen parameter indicates the maximum number of CAs that can appear below this one in a chain. So if you have a CA with a pathlen of zero it can only be used to sign end user certificates and not further CAs.</p> <h2 id="Key-Usage">Key Usage.</h2> <p>Key usage is a multi valued extension consisting of a list of names of the permitted key usages.</p> <p>The supported names are: digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment, keyAgreement, keyCertSign, cRLSign, encipherOnly and decipherOnly.</p> <p>Examples:</p> <pre><code> keyUsage=digitalSignature, nonRepudiation keyUsage=critical, keyCertSign</code></pre> <h2 id="Extended-Key-Usage">Extended Key Usage.</h2> <p>This extensions consists of a list of usages indicating purposes for which the certificate public key can be used for,</p> <p>These can either be object short names or the dotted numerical form of OIDs. While any OID can be used only certain values make sense. In particular the following PKIX, NS and MS values are meaningful:</p> <pre><code> Value Meaning ----- ------- serverAuth SSL/TLS Web Server Authentication. clientAuth SSL/TLS Web Client Authentication. codeSigning Code signing. emailProtection E-mail Protection (S/MIME). timeStamping Trusted Timestamping OCSPSigning OCSP Signing ipsecIKE ipsec Internet Key Exchange msCodeInd Microsoft Individual Code Signing (authenticode) msCodeCom Microsoft Commercial Code Signing (authenticode) msCTLSign Microsoft Trust List Signing msEFS Microsoft Encrypted File System</code></pre> <p>Examples:</p> <pre><code> extendedKeyUsage=critical,codeSigning,1.2.3.4 extendedKeyUsage=serverAuth,clientAuth</code></pre> <h2 id="Subject-Key-Identifier">Subject Key Identifier.</h2> <p>This is really a string extension and can take two possible values. Either the word <b>hash</b> which will automatically follow the guidelines in RFC3280 or a hex string giving the extension value to include. The use of the hex string is strongly discouraged.</p> <p>Example:</p> <pre><code> subjectKeyIdentifier=hash</code></pre> <h2 id="Authority-Key-Identifier">Authority Key Identifier.</h2> <p>The authority key identifier extension permits two options. keyid and issuer: both can take the optional value "always".</p> <p>If the keyid option is present an attempt is made to copy the subject key identifier from the parent certificate. If the value "always" is present then an error is returned if the option fails.</p> <p>The issuer option copies the issuer and serial number from the issuer certificate. This will only be done if the keyid option fails or is not included unless the "always" flag will always include the value.</p> <p>Example:</p> <pre><code> authorityKeyIdentifier=keyid,issuer</code></pre> <h2 id="Subject-Alternative-Name">Subject Alternative Name.</h2> <p>The subject alternative name extension allows various literal values to be included in the configuration file. These include <b>email</b> (an email address) <b>URI</b> a uniform resource indicator, <b>DNS</b> (a DNS domain name), <b>RID</b> (a registered ID: OBJECT IDENTIFIER), <b>IP</b> (an IP address), <b>dirName</b> (a distinguished name) and otherName.</p> <p>The email option include a special 'copy' value. This will automatically include any email addresses contained in the certificate subject name in the extension.</p> <p>The IP address used in the <b>IP</b> options can be in either IPv4 or IPv6 format.</p> <p>The value of <b>dirName</b> should point to a section containing the distinguished name to use as a set of name value pairs. Multi values AVAs can be formed by prefacing the name with a <b>+</b> character.</p> <p>otherName can include arbitrary data associated with an OID: the value should be the OID followed by a semicolon and the content in standard <a href="../man3/ASN1_generate_nconf.html">ASN1_generate_nconf(3)</a> format.</p> <p>Examples:</p> <pre><code> subjectAltName=email:copy,email:my@other.address,URI:http://my.url.here/ subjectAltName=IP:192.168.7.1 subjectAltName=IP:13::17 subjectAltName=email:my@other.address,RID:1.2.3.4 subjectAltName=otherName:1.2.3.4;UTF8:some other identifier subjectAltName=dirName:dir_sect [dir_sect] C=UK O=My Organization OU=My Unit CN=My Name</code></pre> <h2 id="Issuer-Alternative-Name">Issuer Alternative Name.</h2> <p>The issuer alternative name option supports all the literal options of subject alternative name. It does <b>not</b> support the email:copy option because that would not make sense. It does support an additional issuer:copy option that will copy all the subject alternative name values from the issuer certificate (if possible).</p> <p>Example:</p> <pre><code> issuerAltName = issuer:copy</code></pre> <h2 id="Authority-Info-Access">Authority Info Access.</h2> <p>The authority information access extension gives details about how to access certain information relating to the CA. Its syntax is accessOID;location where <i>location</i> has the same syntax as subject alternative name (except that email:copy is not supported). accessOID can be any valid OID but only certain values are meaningful, for example OCSP and caIssuers.</p> <p>Example:</p> <pre><code> authorityInfoAccess = OCSP;URI:http://ocsp.my.host/ authorityInfoAccess = caIssuers;URI:http://my.ca/ca.html</code></pre> <h2 id="CRL-distribution-points">CRL distribution points</h2> <p>This is a multi-valued extension whose options can be either in name:value pair using the same form as subject alternative name or a single value representing a section name containing all the distribution point fields.</p> <p>For a name:value pair a new DistributionPoint with the fullName field set to the given value both the cRLissuer and reasons fields are omitted in this case.</p> <p>In the single option case the section indicated contains values for each field. In this section:</p> <p>If the name is "fullname" the value field should contain the full name of the distribution point in the same format as subject alternative name.</p> <p>If the name is "relativename" then the value field should contain a section name whose contents represent a DN fragment to be placed in this field.</p> <p>The name "CRLIssuer" if present should contain a value for this field in subject alternative name format.</p> <p>If the name is "reasons" the value field should consist of a comma separated field containing the reasons. Valid reasons are: "keyCompromise", "CACompromise", "affiliationChanged", "superseded", "cessationOfOperation", "certificateHold", "privilegeWithdrawn" and "AACompromise".</p> <p>Simple examples:</p> <pre><code> crlDistributionPoints=URI:http://myhost.com/myca.crl crlDistributionPoints=URI:http://my.com/my.crl,URI:http://oth.com/my.crl</code></pre> <p>Full distribution point example:</p> <pre><code> crlDistributionPoints=crldp1_section [crldp1_section] fullname=URI:http://myhost.com/myca.crl CRLissuer=dirName:issuer_sect reasons=keyCompromise, CACompromise [issuer_sect] C=UK O=Organisation CN=Some Name</code></pre> <h2 id="Issuing-Distribution-Point">Issuing Distribution Point</h2> <p>This extension should only appear in CRLs. It is a multi valued extension whose syntax is similar to the "section" pointed to by the CRL distribution points extension with a few differences.</p> <p>The names "reasons" and "CRLissuer" are not recognized.</p> <p>The name "onlysomereasons" is accepted which sets this field. The value is in the same format as the CRL distribution point "reasons" field.</p> <p>The names "onlyuser", "onlyCA", "onlyAA" and "indirectCRL" are also accepted the values should be a boolean value (TRUE or FALSE) to indicate the value of the corresponding field.</p> <p>Example:</p> <pre><code> issuingDistributionPoint=critical, @idp_section [idp_section] fullname=URI:http://myhost.com/myca.crl indirectCRL=TRUE onlysomereasons=keyCompromise, CACompromise [issuer_sect] C=UK O=Organisation CN=Some Name</code></pre> <h2 id="Certificate-Policies">Certificate Policies.</h2> <p>This is a <i>raw</i> extension. All the fields of this extension can be set by using the appropriate syntax.</p> <p>If you follow the PKIX recommendations and just using one OID then you just include the value of that OID. Multiple OIDs can be set separated by commas, for example:</p> <pre><code> certificatePolicies= 1.2.4.5, 1.1.3.4</code></pre> <p>If you wish to include qualifiers then the policy OID and qualifiers need to be specified in a separate section: this is done by using the @section syntax instead of a literal OID value.</p> <p>The section referred to must include the policy OID using the name policyIdentifier, cPSuri qualifiers can be included using the syntax:</p> <pre><code> CPS.nnn=value</code></pre> <p>userNotice qualifiers can be set using the syntax:</p> <pre><code> userNotice.nnn=@notice</code></pre> <p>The value of the userNotice qualifier is specified in the relevant section. This section can include explicitText, organization and noticeNumbers options. explicitText and organization are text strings, noticeNumbers is a comma separated list of numbers. The organization and noticeNumbers options (if included) must BOTH be present. If you use the userNotice option with IE5 then you need the 'ia5org' option at the top level to modify the encoding: otherwise it will not be interpreted properly.</p> <p>Example:</p> <pre><code> certificatePolicies=ia5org,1.2.3.4,1.5.6.7.8,@polsect [polsect] policyIdentifier = 1.3.5.8 CPS.1="http://my.host.name/" CPS.2="http://my.your.name/" userNotice.1=@notice [notice] explicitText="Explicit Text Here" organization="Organisation Name" noticeNumbers=1,2,3,4</code></pre> <p>The <b>ia5org</b> option changes the type of the <i>organization</i> field. In RFC2459 it can only be of type DisplayText. In RFC3280 IA5String is also permissible. Some software (for example some versions of MSIE) may require ia5org.</p> <p>ASN1 type of explicitText can be specified by prepending <b>UTF8</b>, <b>BMP</b> or <b>VISIBLE</b> prefix followed by colon. For example:</p> <pre><code> [notice] explicitText="UTF8:Explicit Text Here"</code></pre> <h2 id="Policy-Constraints">Policy Constraints</h2> <p>This is a multi-valued extension which consisting of the names <b>requireExplicitPolicy</b> or <b>inhibitPolicyMapping</b> and a non negative integer value. At least one component must be present.</p> <p>Example:</p> <pre><code> policyConstraints = requireExplicitPolicy:3</code></pre> <h2 id="Inhibit-Any-Policy">Inhibit Any Policy</h2> <p>This is a string extension whose value must be a non negative integer.</p> <p>Example:</p> <pre><code> inhibitAnyPolicy = 2</code></pre> <h2 id="Name-Constraints">Name Constraints</h2> <p>The name constraints extension is a multi-valued extension. The name should begin with the word <b>permitted</b> or <b>excluded</b> followed by a <b>;</b>. The rest of the name and the value follows the syntax of subjectAltName except email:copy is not supported and the <b>IP</b> form should consist of an IP addresses and subnet mask separated by a <b>/</b>.</p> <p>Examples:</p> <pre><code> nameConstraints=permitted;IP:192.168.0.0/255.255.0.0 nameConstraints=permitted;email:.somedomain.com nameConstraints=excluded;email:.com</code></pre> <h2 id="OCSP-No-Check">OCSP No Check</h2> <p>The OCSP No Check extension is a string extension but its value is ignored.</p> <p>Example:</p> <pre><code> noCheck = ignored</code></pre> <h2 id="TLS-Feature-aka-Must-Staple">TLS Feature (aka Must Staple)</h2> <p>This is a multi-valued extension consisting of a list of TLS extension identifiers. Each identifier may be a number (0..65535) or a supported name. When a TLS client sends a listed extension, the TLS server is expected to include that extension in its reply.</p> <p>The supported names are: <b>status_request</b> and <b>status_request_v2</b>.</p> <p>Example:</p> <pre><code> tlsfeature = status_request</code></pre> <h1 id="DEPRECATED-EXTENSIONS">DEPRECATED EXTENSIONS</h1> <p>The following extensions are non standard, Netscape specific and largely obsolete. Their use in new applications is discouraged.</p> <h2 id="Netscape-String-extensions">Netscape String extensions.</h2> <p>Netscape Comment (<b>nsComment</b>) is a string extension containing a comment which will be displayed when the certificate is viewed in some browsers.</p> <p>Example:</p> <pre><code> nsComment = "Some Random Comment"</code></pre> <p>Other supported extensions in this category are: <b>nsBaseUrl</b>, <b>nsRevocationUrl</b>, <b>nsCaRevocationUrl</b>, <b>nsRenewalUrl</b>, <b>nsCaPolicyUrl</b> and <b>nsSslServerName</b>.</p> <h2 id="Netscape-Certificate-Type">Netscape Certificate Type</h2> <p>This is a multi-valued extensions which consists of a list of flags to be included. It was used to indicate the purposes for which a certificate could be used. The basicConstraints, keyUsage and extended key usage extensions are now used instead.</p> <p>Acceptable values for nsCertType are: <b>client</b>, <b>server</b>, <b>email</b>, <b>objsign</b>, <b>reserved</b>, <b>sslCA</b>, <b>emailCA</b>, <b>objCA</b>.</p> <h1 id="ARBITRARY-EXTENSIONS">ARBITRARY EXTENSIONS</h1> <p>If an extension is not supported by the OpenSSL code then it must be encoded using the arbitrary extension format. It is also possible to use the arbitrary format for supported extensions. Extreme care should be taken to ensure that the data is formatted correctly for the given extension type.</p> <p>There are two ways to encode arbitrary extensions.</p> <p>The first way is to use the word ASN1 followed by the extension content using the same syntax as <a href="../man3/ASN1_generate_nconf.html">ASN1_generate_nconf(3)</a>. For example:</p> <pre><code> 1.2.3.4=critical,ASN1:UTF8String:Some random data 1.2.3.4=ASN1:SEQUENCE:seq_sect [seq_sect] field1 = UTF8:field1 field2 = UTF8:field2</code></pre> <p>It is also possible to use the word DER to include the raw encoded data in any extension.</p> <pre><code> 1.2.3.4=critical,DER:01:02:03:04 1.2.3.4=DER:01020304</code></pre> <p>The value following DER is a hex dump of the DER encoding of the extension Any extension can be placed in this form to override the default behaviour. For example:</p> <pre><code> basicConstraints=critical,DER:00:01:02:03</code></pre> <h1 id="WARNINGS">WARNINGS</h1> <p>There is no guarantee that a specific implementation will process a given extension. It may therefore be sometimes possible to use certificates for purposes prohibited by their extensions because a specific application does not recognize or honour the values of the relevant extensions.</p> <p>The DER and ASN1 options should be used with caution. It is possible to create totally invalid extensions if they are not used carefully.</p> <h1 id="NOTES">NOTES</h1> <p>If an extension is multi-value and a field value must contain a comma the long form must be used otherwise the comma would be misinterpreted as a field separator. For example:</p> <pre><code> subjectAltName=URI:ldap://somehost.com/CN=foo,OU=bar</code></pre> <p>will produce an error but the equivalent form:</p> <pre><code> subjectAltName=@subject_alt_section [subject_alt_section] subjectAltName=URI:ldap://somehost.com/CN=foo,OU=bar</code></pre> <p>is valid.</p> <p>Due to the behaviour of the OpenSSL <b>conf</b> library the same field name can only occur once in a section. This means that:</p> <pre><code> subjectAltName=@alt_section [alt_section] email=steve@here email=steve@there</code></pre> <p>will only recognize the last value. This can be worked around by using the form:</p> <pre><code> [alt_section] email.1=steve@here email.2=steve@there</code></pre> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man1/req.html">req(1)</a>, <a href="../man1/ca.html">ca(1)</a>, <a href="../man1/x509.html">x509(1)</a>, <a href="../man3/ASN1_generate_nconf.html">ASN1_generate_nconf(3)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2004-2020 The OpenSSL Project Authors.

They are functionally equivalent, except for minor differences noted below.</p> <p><b>rehash</b> scans directories and calculates a hash value of each <code>.pem</code>, <code>.crt</code>, <code>.cer</code>, or <code>.crl</code> file in the specified directory list and creates symbolic links for each file, where the name of the link is the hash value. (If the platform does not support symbolic links, a copy is made.) This utility is useful as many programs that use OpenSSL require directories to be set up like this in order to find certificates.</p> <p>If any directories are named on the command line, then those are processed in turn. If not, then the <b>SSL_CERT_DIR</b> environment variable is consulted; this should be a colon-separated list of directories, like the Unix <b>PATH</b> variable. If that is not set then the default directory (installation-specific but often <b>/usr/local/ssl/certs</b>) is processed.</p> <p>In order for a directory to be processed, the user must have write permissions on that directory, otherwise an error will be generated.</p> <p>The links created are of the form <code>HHHHHHHH.D</code>, where each <b>H</b> is a hexadecimal character and <b>D</b> is a single decimal digit. When processing a directory, <b>rehash</b> will first remove all links that have a name in that syntax, even if they are being used for some other purpose. To skip the removal step, use the <b>-n</b> flag. Hashes for CRL's look similar except the letter <b>r</b> appears after the period, like this: <code>HHHHHHHH.rD</code>.</p> <p>Multiple objects may have the same hash; they will be indicated by incrementing the <b>D</b> value. Duplicates are found by comparing the full SHA-1 fingerprint. A warning will be displayed if a duplicate is found.</p> <p>A warning will also be displayed if there are files that cannot be parsed as either a certificate or a CRL or if more than one such object appears in the file.</p> <h2 id="Script-Configuration">Script Configuration</h2> <p>The <b>c_rehash</b> script uses the <b>openssl</b> program to compute the hashes and fingerprints. If not found in the user's <b>PATH</b>, then set the <b>OPENSSL</b> environment variable to the full pathname. Any program can be used, it will be invoked as follows for either a certificate or CRL:</p> <pre><code> $OPENSSL x509 -hash -fingerprint -noout -in FILENAME $OPENSSL crl -hash -fingerprint -noout -in FILENAME</code></pre> <p>where <b>FILENAME</b> is the filename.

In particular you should play with these options <b>before</b> submitting a bug report to an OpenSSL mailing list.</p> <p>A frequent problem when attempting to get client certificates working is that a web client complains it has no certificates or gives an empty list to choose from. This is normally because the server is not sending the clients certificate authority in its "acceptable CA list" when it requests a certificate. By using <a href="../man1/s_client.html">s_client(1)</a> the CA list can be viewed and checked. However, some servers only request client authentication after a specific URL is requested. To obtain the list in this case it is necessary to use the <b>-prexit</b> option of <a href="../man1/s_client.html">s_client(1)</a> and send an HTTP request for an appropriate page.</p> <p>If a certificate is specified on the command line using the <b>-cert</b> option it will not be used unless the server specifically requests a client certificate.

It can be used for</p> <pre><code> o Creation and management of private keys, public keys and parameters o Public key cryptographic operations o Creation of X.509 certificates, CSRs and CRLs o Calculation of Message Digests o Encryption and Decryption with Ciphers o SSL/TLS Client and Server Tests o Handling of S/MIME signed or encrypted mail o Time Stamp requests, generation and verification</code></pre> <h1 id="COMMAND-SUMMARY">COMMAND SUMMARY</h1> <p>The <b>openssl</b> program provides a rich variety of commands (<i>command</i> in the SYNOPSIS above), each of which often has a wealth of options and arguments (<i>command_opts</i> and <i>command_args</i> in the SYNOPSIS).</p> <p>Detailed documentation and use cases for most standard subcommands are available (e.g., <a href="../man1/x509.html">x509(1)</a> or <a href="../man1/openssl-x509.html">openssl-x509(1)</a>).</p> <p>Many commands use an external configuration file for some or all of their arguments and have a <b>-config</b> option to specify that file. The environment variable <b>OPENSSL_CONF</b> can be used to specify the location of the file. If the environment variable is not specified, then the file is named <b>openssl.cnf</b> in the default certificate storage area, whose value depends on the configuration flags specified when the OpenSSL was built.</p> <p>The list parameters <b>standard-commands</b>, <b>digest-commands</b>, and <b>cipher-commands</b> output a list (one entry per line) of the names of all standard commands, message digest commands, or cipher commands, respectively, that are available in the present <b>openssl</b> utility.</p> <p>The list parameters <b>cipher-algorithms</b> and <b>digest-algorithms</b> list all cipher and message digest names, one entry per line. Aliases are listed as:</p> <pre><code> from => to</code></pre> <p>The list parameter <b>public-key-algorithms</b> lists all supported public key algorithms.</p> <p>The command <b>no-</b><i>XXX</i> tests whether a command of the specified name is available. If no command named <i>XXX</i> exists, it returns 0 (success) and prints <b>no-</b><i>XXX</i>; otherwise it returns 1 and prints <i>XXX</i>. In both cases, the output goes to <b>stdout</b> and nothing is printed to <b>stderr</b>. Additional command line arguments are always ignored. Since for each cipher there is a command of the same name, this provides an easy way for shell scripts to test for the availability of ciphers in the <b>openssl</b> program. (<b>no-</b><i>XXX</i> is not able to detect pseudo-commands such as <b>quit</b>, <b>list</b>, or <b>no-</b><i>XXX</i> itself.)</p> <h2 id="Standard-Commands">Standard Commands</h2> <dl> <dt id="asn1parse"><b>asn1parse</b></dt> <dd> <p>Parse an ASN.1 sequence.</p> </dd> <dt id="ca"><b>ca</b></dt> <dd> <p>Certificate Authority (CA) Management.</p> </dd> <dt id="ciphers"><b>ciphers</b></dt> <dd> <p>Cipher Suite Description Determination.</p> </dd> <dt id="cms"><b>cms</b></dt> <dd> <p>CMS (Cryptographic Message Syntax) utility.</p> </dd> <dt id="crl"><b>crl</b></dt> <dd> <p>Certificate Revocation List (CRL) Management.</p> </dd> <dt id="crl2pkcs7"><b>crl2pkcs7</b></dt> <dd> <p>CRL to PKCS#7 Conversion.</p> </dd> <dt id="dgst"><b>dgst</b></dt> <dd> <p>Message Digest Calculation.</p> </dd> <dt id="dh"><b>dh</b></dt> <dd> <p>Diffie-Hellman Parameter Management.

The OpenSSL operations and options are indicated below.</p> <p>Unless otherwise mentioned all algorithms support the <b>digest:alg</b> option which specifies the digest in use for sign, verify and verifyrecover operations. The value <b>alg</b> should represent a digest name as used in the EVP_get_digestbyname() function for example <b>sha1</b>. This value is not used to hash the input data. It is used (by some algorithms) for sanity-checking the lengths of data passed in to the <b>pkeyutl</b> and for creating the structures that make up the signature (e.g. <b>DigestInfo</b> in RSASSA PKCS#1 v1.5 signatures).</p> <p>This utility does not hash the input data but rather it will use the data directly as input to the signature algorithm. Depending on the key type, signature type, and mode of padding, the maximum acceptable lengths of input data differ. The signed data can't be longer than the key modulus with RSA. In case of ECDSA and DSA the data shouldn't be longer than the field size, otherwise it will be silently truncated to the field size. In any event the input size must not be larger than the largest supported digest size.</p> <p>In other words, if the value of digest is <b>sha1</b> the input should be the 20 bytes long binary encoding of the SHA-1 hash function output.</p> <p>The Ed25519 and Ed448 signature algorithms are not supported by this utility. They accept non-hashed input, but this utility can only be used to sign hashed input.</p> <h1 id="RSA-ALGORITHM">RSA ALGORITHM</h1> <p>The RSA algorithm generally supports the encrypt, decrypt, sign, verify and verifyrecover operations. However, some padding modes support only a subset of these operations. The following additional <b>pkeyopt</b> values are supported:</p> <dl> <dt id="rsa_padding_mode:mode"><b>rsa_padding_mode:mode</b></dt> <dd> <p>This sets the RSA padding mode. Acceptable values for <b>mode</b> are <b>pkcs1</b> for PKCS#1 padding, <b>sslv23</b> for SSLv23 padding, <b>none</b> for no padding, <b>oaep</b> for <b>OAEP</b> mode, <b>x931</b> for X9.31 mode and <b>pss</b> for PSS.</p> <p>In PKCS#1 padding if the message digest is not set then the supplied data is signed or verified directly instead of using a <b>DigestInfo</b> structure. If a digest is set then the a <b>DigestInfo</b> structure is used and its the length must correspond to the digest type.</p> <p>For <b>oaep</b> mode only encryption and decryption is supported.</p> <p>For <b>x931</b> if the digest type is set it is used to format the block data otherwise the first byte is used to specify the X9.31 digest ID. Sign, verify and verifyrecover are can be performed in this mode.</p> <p>For <b>pss</b> mode only sign and verify are supported and the digest type must be specified.</p> </dd> <dt id="rsa_pss_saltlen:len"><b>rsa_pss_saltlen:len</b></dt> <dd> <p>For <b>pss</b> mode only this option specifies the salt length. Three special values are supported: "digest" sets the salt length to the digest length, "max" sets the salt length to the maximum permissible value. When verifying "auto" causes the salt length to be automatically determined based on the <b>PSS</b> block structure.</p> </dd> <dt id="rsa_mgf1_md:digest"><b>rsa_mgf1_md:digest</b></dt> <dd> <p>For PSS and OAEP padding sets the MGF1 digest. If the MGF1 digest is not explicitly set in PSS mode then the signing digest is used.</p> </dd> <dt id="rsa_oaep_md:digest"><b>rsa_oaep_md:</b><i>digest</i></dt> <dd> <p>Sets the digest used for the OAEP hash function. If not explicitly set then SHA1 is used.</p> </dd> </dl> <h1 id="RSA-PSS-ALGORITHM">RSA-PSS ALGORITHM</h1> <p>The RSA-PSS algorithm is a restricted version of the RSA algorithm which only supports the sign and verify operations with PSS padding. The following additional <b>pkeyopt</b> values are supported:</p> <dl> <dt id="rsa_padding_mode:mode-rsa_pss_saltlen:len-rsa_mgf1_md:digest"><b>rsa_padding_mode:mode</b>, <b>rsa_pss_saltlen:len</b>, <b>rsa_mgf1_md:digest</b></dt> <dd> <p>These have the same meaning as the <b>RSA</b> algorithm with some additional restrictions. The padding mode can only be set to <b>pss</b> which is the default value.</p> <p>If the key has parameter restrictions than the digest, MGF1 digest and salt length are set to the values specified in the parameters. The digest and MG cannot be changed and the salt length cannot be set to a value less than the minimum restriction.</p> </dd> </dl> <h1 id="DSA-ALGORITHM">DSA ALGORITHM</h1> <p>The DSA algorithm supports signing and verification operations only. Currently there are no additional <b>-pkeyopt</b> options other than <b>digest</b>. The SHA1 digest is assumed by default.</p> <h1 id="DH-ALGORITHM">DH ALGORITHM</h1> <p>The DH algorithm only supports the derivation operation and no additional <b>-pkeyopt</b> options.</p> <h1 id="EC-ALGORITHM">EC ALGORITHM</h1> <p>The EC algorithm supports sign, verify and derive operations.

Check out the <b>POLICY FORMAT</b> section for more information.</p> </dd> <dt id="msie_hack"><b>-msie_hack</b></dt> <dd> <p>This is a deprecated option to make <b>ca</b> work with very old versions of the IE certificate enrollment control "certenr3". It used UniversalStrings for almost everything. Since the old control has various security bugs its use is strongly discouraged.</p> </dd> <dt id="preserveDN"><b>-preserveDN</b></dt> <dd> <p>Normally the DN order of a certificate is the same as the order of the fields in the relevant policy section. When this option is set the order is the same as the request. This is largely for compatibility with the older IE enrollment control which would only accept certificates if their DNs match the order of the request. This is not needed for Xenroll.</p> </dd> <dt id="noemailDN"><b>-noemailDN</b></dt> <dd> <p>The DN of a certificate can contain the EMAIL field if present in the request DN, however, it is good policy just having the e-mail set into the altName extension of the certificate. When this option is set the EMAIL field is removed from the certificate' subject and set only in the, eventually present, extensions. The <b>email_in_dn</b> keyword can be used in the configuration file to enable this behaviour.</p> </dd> <dt id="batch"><b>-batch</b></dt> <dd> <p>This sets the batch mode.

The engine will then be set as the default for all available algorithms.</p> </dd> <dt id="subj-arg"><b>-subj arg</b></dt> <dd> <p>Supersedes subject name given in the request. The arg must be formatted as <i>/type0=value0/type1=value1/type2=...</i>. Keyword characters may be escaped by \ (backslash), and whitespace is retained. Empty values are permitted, but the corresponding type will not be included in the resulting certificate.</p> </dd> <dt id="utf8"><b>-utf8</b></dt> <dd> <p>This option causes field values to be interpreted as UTF8 strings, by default they are interpreted as ASCII. This means that the field values, whether prompted from a terminal or obtained from a configuration file, must be valid UTF8 strings.</p> </dd> <dt id="create_serial"><b>-create_serial</b></dt> <dd> <p>If reading serial from the text file as specified in the configuration fails, specifying this option creates a new random serial to be used as next serial number. To get random serial numbers, use the <b>-rand_serial</b> flag instead; this should only be used for simple error-recovery.</p> </dd> <dt id="rand_serial"><b>-rand_serial</b></dt> <dd> <p>Generate a large random number to use as the serial number. This overrides any option or configuration to use a serial number file.</p> </dd> <dt id="multivalue-rdn"><b>-multivalue-rdn</b></dt> <dd> <p>This option causes the -subj argument to be interpreted with full support for multivalued RDNs. Example:</p> <p><i>/DC=org/DC=OpenSSL/DC=users/UID=123456+CN=John Doe</i></p> <p>If -multi-rdn is not used then the UID value is <i>123456+CN=John Doe</i>.</p> </dd> <dt id="rand-file"><b>-rand file...</b></dt> <dd> <p>A file or files containing random data used to seed the random number generator.

That is the days from now to place in the CRL nextUpdate field.</p> </dd> <dt id="crlhours-num"><b>-crlhours num</b></dt> <dd> <p>The number of hours before the next CRL is due.</p> </dd> <dt id="revoke-filename"><b>-revoke filename</b></dt> <dd> <p>A filename containing a certificate to revoke.</p> </dd> <dt id="valid-filename"><b>-valid filename</b></dt> <dd> <p>A filename containing a certificate to add a Valid certificate entry.</p> </dd> <dt id="status-serial"><b>-status serial</b></dt> <dd> <p>Displays the revocation status of the certificate with the specified serial number and exits.</p> </dd> <dt id="updatedb"><b>-updatedb</b></dt> <dd> <p>Updates the database index to purge expired certificates.</p> </dd> <dt id="crl_reason-reason"><b>-crl_reason reason</b></dt> <dd> <p>Revocation reason, where <b>reason</b> is one of: <b>unspecified</b>, <b>keyCompromise</b>, <b>CACompromise</b>, <b>affiliationChanged</b>, <b>superseded</b>, <b>cessationOfOperation</b>, <b>certificateHold</b> or <b>removeFromCRL</b>. The matching of <b>reason</b> is case insensitive.

Although any OID can be used only <b>holdInstructionNone</b> (the use of which is discouraged by RFC2459) <b>holdInstructionCallIssuer</b> or <b>holdInstructionReject</b> will normally be used.</p> </dd> <dt id="crl_compromise-time"><b>-crl_compromise time</b></dt> <dd> <p>This sets the revocation reason to <b>keyCompromise</b> and the compromise time to <b>time</b>. <b>time</b> should be in GeneralizedTime format that is <b>YYYYMMDDHHMMSSZ</b>.</p> </dd> <dt id="crl_CA_compromise-time"><b>-crl_CA_compromise time</b></dt> <dd> <p>This is the same as <b>crl_compromise</b> except the revocation reason is set to <b>CACompromise</b>.</p> </dd> <dt id="crlexts-section"><b>-crlexts section</b></dt> <dd> <p>The section of the configuration file containing CRL extensions to include. If no CRL extension section is present then a V1 CRL is created, if the CRL extension section is present (even if it is empty) then a V2 CRL is created.

However, to make CA certificate roll-over easier, it's recommended to use the value <b>no</b>, especially if combined with the <b>-selfsign</b> command line option.</p> <p>Note that it is valid in some circumstances for certificates to be created without any subject.

If the value is "match" then the field value must match the same field in the CA certificate. If the value is "supplied" then it must be present. If the value is "optional" then it may be present. Any fields not mentioned in the policy section are silently deleted, unless the <b>-preserveDN</b> option is set but this can be regarded more of a quirk than intended behaviour.</p> <h1 id="SPKAC-FORMAT">SPKAC FORMAT</h1> <p>The input to the <b>-spkac</b> command line option is a Netscape signed public key and challenge. This will usually come from the <b>KEYGEN</b> tag in an HTML form to create a new private key. It is however possible to create SPKACs using the <b>spkac</b> utility.</p> <p>The file should contain the variable SPKAC set to the value of the SPKAC and also the required DN components as name value pairs. If you need to include the same component twice then it can be preceded by a number and a '.'.</p> <p>When processing SPKAC format, the output is DER if the <b>-out</b> flag is used, but PEM format if sending to stdout or the <b>-outdir</b> flag is used.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Note: these examples assume that the <b>ca</b> directory structure is already set up and the relevant files already exist. This usually involves creating a CA certificate and private key with <b>req</b>, a serial number file and an empty index file and placing them in the relevant directories.</p> <p>To use the sample configuration file below the directories demoCA, demoCA/private and demoCA/newcerts would be created. The CA certificate would be copied to demoCA/cacert.pem and its private key to demoCA/private/cakey.pem.

It was not supposed to be used as a full blown CA itself: nevertheless some people are using it for this purpose.</p> <p>The <b>ca</b> command is effectively a single user command: no locking is done on the various files and attempts to run more than one <b>ca</b> command on the same database can have unpredictable results.</p> <p>The <b>copy_extensions</b> option should be used with caution. If care is not taken then it can be a security risk. For example if a certificate request contains a basicConstraints extension with CA:TRUE and the <b>copy_extensions</b> value is set to <b>copyall</b> and the user does not spot this when the certificate is displayed then this will hand the requester a valid CA certificate.</p> <p>This situation can be avoided by setting <b>copy_extensions</b> to <b>copy</b> and including basicConstraints with CA:FALSE in the configuration file. Then if the request contains a basicConstraints extension it will be ignored.</p> <p>It is advisable to also include values for other extensions such as <b>keyUsage</b> to prevent a request supplying its own values.</p> <p>Additional restrictions can be placed on the CA certificate itself. For example if the CA certificate has:</p> <pre><code> basicConstraints = CA:TRUE, pathlen:0</code></pre> <p>then even if a certificate is issued with CA:TRUE it will not be valid.</p> <h1 id="HISTORY">HISTORY</h1> <p>Since OpenSSL 1.1.1, the program follows RFC5280. Specifically, certificate validity period (specified by any of <b>-startdate</b>, <b>-enddate</b> and <b>-days</b>) will be encoded as UTCTime if the dates are earlier than year 2049 (included), and as GeneralizedTime if the dates are in year 2050 or later.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man1/req.html">req(1)</a>, <a href="../man1/spkac.html">spkac(1)</a>, <a href="../man1/x509.html">x509(1)</a>, <a href="../man1/CA.pl.html">CA.pl(1)</a>, <a href="../man5/config.html">config(5)</a>, <a href="../man5/x509v3_config.html">x509v3_config(5)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2021 The OpenSSL Project Authors.

The format is described in the next section.</p> </dd> </dl> <h1 id="DISTINGUISHED-NAME-AND-ATTRIBUTE-SECTION-FORMAT">DISTINGUISHED NAME AND ATTRIBUTE SECTION FORMAT</h1> <p>There are two separate formats for the distinguished name and attribute sections. If the <b>prompt</b> option is set to <b>no</b> then these sections just consist of field names and values: for example,</p> <pre><code> CN=My Name OU=My Organization emailAddress=someone@somewhere.org</code></pre> <p>This allows external programs (e.g. GUI based) to generate a template file with all the field names and values and just pass it to <b>req</b>. An example of this kind of configuration file is contained in the <b>EXAMPLES</b> section.</p> <p>Alternatively if the <b>prompt</b> option is absent or not set to <b>no</b> then the file contains field prompting information. It consists of lines of the form:</p> <pre><code> fieldName="prompt" fieldName_default="default field value" fieldName_min= 2 fieldName_max= 4</code></pre> <p>"fieldName" is the field name being used, for example commonName (or CN). The "prompt" string is used to ask the user to enter the relevant details. If the user enters nothing then the default value is used if no default value is present then the field is omitted. A field can still be omitted if a default value is present if the user just enters the '.' character.</p> <p>The number of characters entered must be between the fieldName_min and fieldName_max limits: there may be additional restrictions based on the field being used (for example countryName can only ever be two characters long and must fit in a PrintableString).</p> <p>Some fields (such as organizationName) can be used more than once in a DN. This presents a problem because configuration files will not recognize the same name occurring twice. To avoid this problem if the fieldName contains some characters followed by a full stop they will be ignored. So for example a second organizationName can be input by calling it "1.organizationName".</p> <p>The actual permitted field names are any object identifier short or long names. These are compiled into OpenSSL and include the usual values such as commonName, countryName, localityName, organizationName, organizationalUnitName, stateOrProvinceName. Additionally emailAddress is included as well as name, surname, givenName, initials, and dnQualifier.</p> <p>Additional object identifiers can be defined with the <b>oid_file</b> or <b>oid_section</b> options in the configuration file. Any additional fields will be treated as though they were a DirectoryString.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Examine and verify certificate request:</p> <pre><code> openssl req -in req.pem -text -verify -noout</code></pre> <p>Create a private key and then generate a certificate request from it:</p> <pre><code> openssl genrsa -out key.pem 2048 openssl req -new -key key.pem -out req.pem</code></pre> <p>The same but just using req:</p> <pre><code> openssl req -newkey rsa:2048 -keyout key.pem -out req.pem</code></pre> <p>Generate a self signed root certificate:</p> <pre><code> openssl req -x509 -newkey rsa:2048 -keyout key.pem -out req.pem</code></pre> <p>Example of a file pointed to by the <b>oid_file</b> option:</p> <pre><code> 1.2.3.4 shortName A longer Name 1.2.3.6 otherName Other longer Name</code></pre> <p>Example of a section pointed to by <b>oid_section</b> making use of variable expansion:</p> <pre><code> testoid1=1.2.3.5 testoid2=${testoid1}.6</code></pre> <p>Sample configuration file prompting for field values:</p> <pre><code> [ req ] default_bits = 2048 default_keyfile = privkey.pem distinguished_name = req_distinguished_name attributes = req_attributes req_extensions = v3_ca dirstring_type = nobmp [ req_distinguished_name ] countryName = Country Name (2 letter code) countryName_default = AU countryName_min = 2 countryName_max = 2 localityName = Locality Name (eg, city) organizationalUnitName = Organizational Unit Name (eg, section) commonName = Common Name (eg, YOUR name) commonName_max = 64 emailAddress = Email Address emailAddress_max = 40 [ req_attributes ] challengePassword = A challenge password challengePassword_min = 4 challengePassword_max = 20 [ v3_ca ] subjectKeyIdentifier=hash authorityKeyIdentifier=keyid:always,issuer:always basicConstraints = critical, CA:true</code></pre> <p>Sample configuration containing all field values:</p> <pre><code> RANDFILE = $ENV::HOME/.rnd [ req ] default_bits = 2048 default_keyfile = keyfile.pem distinguished_name = req_distinguished_name attributes = req_attributes prompt = no output_password = mypass [ req_distinguished_name ] C = GB ST = Test State or Province L = Test Locality O = Organization Name OU = Organizational Unit Name CN = Common Name emailAddress = test@email.address [ req_attributes ] challengePassword = A challenge password</code></pre> <p>Example of giving the most common attributes (subject and extensions) on the command line:</p> <pre><code> openssl req -new -subj "/C=GB/CN=foo" \ -addext "subjectAltName = DNS:foo.co.uk" \ -addext "certificatePolicies = 1.2.3.4" \ -newkey rsa:2048 -keyout key.pem -out req.pem</code></pre> <h1 id="NOTES">NOTES</h1> <p>The header and footer lines in the <b>PEM</b> format are normally:</p> <pre><code> -----BEGIN CERTIFICATE REQUEST----- -----END CERTIFICATE REQUEST-----</code></pre> <p>some software (some versions of Netscape certificate server) instead needs:</p> <pre><code> -----BEGIN NEW CERTIFICATE REQUEST----- -----END NEW CERTIFICATE REQUEST-----</code></pre> <p>which is produced with the <b>-newhdr</b> option but is otherwise compatible.

Certain operations (like examining a certificate request) don't need a configuration file so its use isn't enforced. Generation of certificates or requests however does need a configuration file. This could be regarded as a bug.</p> <p>Another puzzling message is this:</p> <pre><code> Attributes: a0:00</code></pre> <p>this is displayed when no attributes are present and the request includes the correct empty <b>SET OF</b> structure (the DER encoding of which is 0xa0 0x00).

See the description of the command line option <b>-asn1-kludge</b> for more information.</p> <h1 id="BUGS">BUGS</h1> <p>OpenSSL's handling of T61Strings (aka TeletexStrings) is broken: it effectively treats them as ISO-8859-1 (Latin 1), Netscape and MSIE have similar behaviour. This can cause problems if you need characters that aren't available in PrintableStrings and you don't want to or can't use BMPStrings.</p> <p>As a consequence of the T61String handling the only correct way to represent accented characters in OpenSSL is to use a BMPString: unfortunately Netscape currently chokes on these.

This directory must be a standard certificate directory: that is a hash of each subject name (using <b>x509 -hash</b>) should be linked to each certificate.</p> </dd> <dt id="no-CAfile"><b>-no-CAfile</b></dt> <dd> <p>Do not load the trusted CA certificates from the default file location</p> </dd> <dt id="no-CApath"><b>-no-CApath</b></dt> <dd> <p>Do not load the trusted CA certificates from the default directory location</p> </dd> <dt id="md-digest"><b>-md digest</b></dt> <dd> <p>Digest algorithm to use when signing or resigning. If not present then the default digest algorithm for the signing key will be used (usually SHA1).</p> </dd> <dt id="cipher"><b>-<i>cipher</i></b></dt> <dd> <p>The encryption algorithm to use. For example triple DES (168 bits) - <b>-des3</b> or 256 bit AES - <b>-aes256</b>. Any standard algorithm name (as used by the EVP_get_cipherbyname() function) can also be used preceded by a dash, for example <b>-aes-128-cbc</b>. See <a href="../man1/enc.html">enc(1)</a> for a list of ciphers supported by your version of OpenSSL.</p> <p>If not specified triple DES is used. Only used with <b>-encrypt</b> and <b>-EncryptedData_create</b> commands.</p> </dd> <dt id="nointern"><b>-nointern</b></dt> <dd> <p>When verifying a message normally certificates (if any) included in the message are searched for the signing certificate. With this option only the certificates specified in the <b>-certfile</b> option are used. The supplied certificates can still be used as untrusted CAs however.</p> </dd> <dt id="noverify"><b>-noverify</b></dt> <dd> <p>Do not verify the signers certificate of a signed message.</p> </dd> <dt id="nocerts"><b>-nocerts</b></dt> <dd> <p>When signing a message the signer's certificate is normally included with this option it is excluded. This will reduce the size of the signed message but the verifier must have a copy of the signers certificate available locally (passed using the <b>-certfile</b> option for example).</p> </dd> <dt id="noattr"><b>-noattr</b></dt> <dd> <p>Normally when a message is signed a set of attributes are included which include the signing time and supported symmetric algorithms. With this option they are not included.</p> </dd> <dt id="nosmimecap"><b>-nosmimecap</b></dt> <dd> <p>Exclude the list of supported algorithms from signed attributes, other options such as signing time and content type are still included.</p> </dd> <dt id="binary"><b>-binary</b></dt> <dd> <p>Normally the input message is converted to "canonical" format which is effectively using CR and LF as end of line: as required by the S/MIME specification. When this option is present no translation occurs. This is useful when handling binary data which may not be in MIME format.</p> </dd> <dt id="crlfeol"><b>-crlfeol</b></dt> <dd> <p>Normally the output file uses a single <b>LF</b> as end of line. When this option is present <b>CRLF</b> is used instead.</p> </dd> <dt id="asciicrlf"><b>-asciicrlf</b></dt> <dd> <p>When signing use ASCII CRLF format canonicalisation. This strips trailing whitespace from all lines, deletes trailing blank lines at EOF and sets the encapsulated content type. This option is normally used with detached content and an output signature format of DER. This option is not normally needed when verifying as it is enabled automatically if the encapsulated content format is detected.</p> </dd> <dt id="nodetach"><b>-nodetach</b></dt> <dd> <p>When signing a message use opaque signing: this form is more resistant to translation by mail relays but it cannot be read by mail agents that do not support S/MIME. Without this option cleartext signing with the MIME type multipart/signed is used.</p> </dd> <dt id="certfile-file"><b>-certfile file</b></dt> <dd> <p>Allows additional certificates to be specified. When signing these will be included with the message. When verifying these will be searched for the signers certificates. The certificates should be in PEM format.</p> </dd> <dt id="certsout-file"><b>-certsout file</b></dt> <dd> <p>Any certificates contained in the message are written to <b>file</b>.</p> </dd> <dt id="signer-file"><b>-signer file</b></dt> <dd> <p>A signing certificate when signing or resigning a message, this option can be used multiple times if more than one signer is required. If a message is being verified then the signers certificates will be written to this file if the verification was successful.</p> </dd> <dt id="recip-file"><b>-recip file</b></dt> <dd> <p>When decrypting a message this specifies the recipients certificate. The certificate must match one of the recipients of the message or an error occurs.</p> <p>When encrypting a message this option may be used multiple times to specify each recipient. This form <b>must</b> be used if customised parameters are required (for example to specify RSA-OAEP).</p> <p>Only certificates carrying RSA, Diffie-Hellman or EC keys are supported by this option.</p> </dd> <dt id="keyid"><b>-keyid</b></dt> <dd> <p>Use subject key identifier to identify certificates instead of issuer name and serial number. The supplied certificate <b>must</b> include a subject key identifier extension. Supported by <b>-sign</b> and <b>-encrypt</b> options.</p> </dd> <dt id="receipt_request_all--receipt_request_first"><b>-receipt_request_all</b>, <b>-receipt_request_first</b></dt> <dd> <p>For <b>-sign</b> option include a signed receipt request. Indicate requests should be provided by all recipient or first tier recipients (those mailed directly and not from a mailing list). Ignored it <b>-receipt_request_from</b> is included.</p> </dd> <dt id="receipt_request_from-emailaddress"><b>-receipt_request_from emailaddress</b></dt> <dd> <p>For <b>-sign</b> option include a signed receipt request. Add an explicit email address where receipts should be supplied.</p> </dd> <dt id="receipt_request_to-emailaddress"><b>-receipt_request_to emailaddress</b></dt> <dd> <p>Add an explicit email address where signed receipts should be sent to. This option <b>must</b> but supplied if a signed receipt it requested.</p> </dd> <dt id="receipt_request_print"><b>-receipt_request_print</b></dt> <dd> <p>For the <b>-verify</b> operation print out the contents of any signed receipt requests.</p> </dd> <dt id="secretkey-key"><b>-secretkey key</b></dt> <dd> <p>Specify symmetric key to use. The key must be supplied in hex format and be consistent with the algorithm used. Supported by the <b>-EncryptedData_encrypt</b> <b>-EncryptedData_decrypt</b>, <b>-encrypt</b> and <b>-decrypt</b> options. When used with <b>-encrypt</b> or <b>-decrypt</b> the supplied key is used to wrap or unwrap the content encryption key using an AES key in the <b>KEKRecipientInfo</b> type.</p> </dd> <dt id="secretkeyid-id"><b>-secretkeyid id</b></dt> <dd> <p>The key identifier for the supplied symmetric key for <b>KEKRecipientInfo</b> type. This option <b>must</b> be present if the <b>-secretkey</b> option is used with <b>-encrypt</b>. With <b>-decrypt</b> operations the <b>id</b> is used to locate the relevant key if it is not supplied then an attempt is used to decrypt any <b>KEKRecipientInfo</b> structures.</p> </dd> <dt id="econtent_type-type"><b>-econtent_type type</b></dt> <dd> <p>Set the encapsulated content type to <b>type</b> if not supplied the <b>Data</b> type is used. The <b>type</b> argument can be any valid OID name in either text or numerical format.</p> </dd> <dt id="inkey-file"><b>-inkey file</b></dt> <dd> <p>The private key to use when signing or decrypting. This must match the corresponding certificate. If this option is not specified then the private key must be included in the certificate file specified with the <b>-recip</b> or <b>-signer</b> file. When signing this option can be used multiple times to specify successive keys.</p> </dd> <dt id="keyopt-name:opt"><b>-keyopt name:opt</b></dt> <dd> <p>For signing and encryption this option can be used multiple times to set customised parameters for the preceding key or certificate. It can currently be used to set RSA-PSS for signing, RSA-OAEP for encryption or to modify default parameters for ECDH.</p> </dd> <dt id="passin-arg"><b>-passin arg</b></dt> <dd> <p>The private key password source. For more information about the format of <b>arg</b> see <a href="../man1/openssl.html">"Pass Phrase Options" in openssl(1)</a>.</p> </dd> <dt id="rand-file"><b>-rand file...</b></dt> <dd> <p>A file or files containing random data used to seed the random number generator.

Some mail programs will automatically add a blank line. Piping the mail directly to sendmail is one way to achieve the correct format.</p> <p>The supplied message to be signed or encrypted must include the necessary MIME headers or many S/MIME clients won't display it properly (if at all). You can use the <b>-text</b> option to automatically add plain text headers.</p> <p>A "signed and encrypted" message is one where a signed message is then encrypted. This can be produced by encrypting an already signed message: see the examples section.</p> <p>This version of the program only allows one signer per message but it will verify multiple signers on received messages. Some S/MIME clients choke if a message contains multiple signers. It is possible to sign messages "in parallel" by signing an already signed message.</p> <p>The options <b>-encrypt</b> and <b>-decrypt</b> reflect common usage in S/MIME clients. Strictly speaking these process CMS enveloped data: CMS encrypted data is used for other purposes.</p> <p>The <b>-resign</b> option uses an existing message digest when adding a new signer. This means that attributes must be present in at least one existing signer using the same message digest or this operation will fail.</p> <p>The <b>-stream</b> and <b>-indef</b> options enable streaming I/O support. As a result the encoding is BER using indefinite length constructed encoding and no longer DER. Streaming is supported for the <b>-encrypt</b> operation and the <b>-sign</b> operation if the content is not detached.</p> <p>Streaming is always used for the <b>-sign</b> operation with detached data but since the content is no longer part of the CMS structure the encoding remains DER.</p> <p>If the <b>-decrypt</b> option is used without a recipient certificate then an attempt is made to locate the recipient by trying each potential recipient in turn using the supplied private key. To thwart the MMA attack (Bleichenbacher's attack on PKCS #1 v1.5 RSA padding) all recipients are tried whether they succeed or not and if no recipients match the message is "decrypted" using a random key which will typically output garbage. The <b>-debug_decrypt</b> option can be used to disable the MMA attack protection and return an error if no recipient can be found: this option should be used with caution.

The first form doesn't work with engine-provided ciphers, because this form is processed before the configuration file is read and any ENGINEs loaded. Use the <b>list</b> command to get a list of supported ciphers.</p> <p>Engines which provide entirely new encryption algorithms (such as the ccgost engine which provides gost89 algorithm) should be configured in the configuration file. Engines specified on the command line using -engine options can only be used for hardware-assisted implementations of ciphers which are supported by the OpenSSL core or another engine specified in the configuration file.</p> <p>When the enc command lists supported ciphers, ciphers provided by engines, specified in the configuration files are listed too.</p> <p>A password will be prompted for to derive the key and IV if necessary.</p> <p>The <b>-salt</b> option should <b>ALWAYS</b> be used if the key is being derived from a password unless you want compatibility with previous versions of OpenSSL.</p> <p>Without the <b>-salt</b> option it is possible to perform efficient dictionary attacks on the password and to attack stream cipher encrypted data. The reason for this is that without the salt the same password always generates the same encryption key. When the salt is being used the first eight bytes of the encrypted data are reserved for the salt: it is generated at random when encrypting a file and read from the encrypted file when it is decrypted.</p> <p>Some of the ciphers do not have large keys and others have security implications if not used correctly. A beginner is advised to just use a strong block cipher, such as AES, in CBC mode.</p> <p>All the block ciphers normally use PKCS#5 padding, also known as standard block padding. This allows a rudimentary integrity or password check to be performed. However, since the chance of random data passing the test is better than 1 in 256 it isn't a very good test.</p> <p>If padding is disabled then the input data must be a multiple of the cipher block length.</p> <p>All RC2 ciphers have the same key and effective key length.</p> <p>Blowfish and RC5 algorithms use a 128 bit key.</p> <h1 id="SUPPORTED-CIPHERS">SUPPORTED CIPHERS</h1> <p>Note that some of these ciphers can be disabled at compile time and some are available only if an appropriate engine is configured in the configuration file. The output of the <b>enc</b> command run with the <b>-ciphers</b> option (that is <b>openssl enc -ciphers</b>) produces a list of ciphers, supported by your version of OpenSSL, including ones provided by configured engines.</p> <p>The <b>enc</b> program does not support authenticated encryption modes like CCM and GCM, and will not support such modes in the future. The <b>enc</b> interface by necessity must begin streaming output (e.g., to standard output when <b>-out</b> is not used) before the authentication tag could be validated, leading to the usage of <b>enc</b> in pipelines that begin processing untrusted data and are not capable of rolling back upon authentication failure. The AEAD modes currently in common use also suffer from catastrophic failure of confidentiality and/or integrity upon reuse of key/iv/nonce, and since <b>enc</b> places the entire burden of key/iv/nonce management upon the user, the risk of exposing AEAD modes is too great to allow. These key/iv/nonce management issues also affect other modes currently exposed in <b>enc</b>, but the failure modes are less extreme in these cases, and the functionality cannot be removed with a stable release branch. For bulk encryption of data, whether using authenticated encryption modes or other modes, <a href="../man1/cms.html">cms(1)</a> is recommended, as it provides a standard data format and performs the needed key/iv/nonce management.</p> <pre><code> base64 Base 64 bf-cbc Blowfish in CBC mode bf Alias for bf-cbc blowfish Alias for bf-cbc bf-cfb Blowfish in CFB mode bf-ecb Blowfish in ECB mode bf-ofb Blowfish in OFB mode cast-cbc CAST in CBC mode cast Alias for cast-cbc cast5-cbc CAST5 in CBC mode cast5-cfb CAST5 in CFB mode cast5-ecb CAST5 in ECB mode cast5-ofb CAST5 in OFB mode chacha20 ChaCha20 algorithm des-cbc DES in CBC mode des Alias for des-cbc des-cfb DES in CFB mode des-ofb DES in OFB mode des-ecb DES in ECB mode des-ede-cbc Two key triple DES EDE in CBC mode des-ede Two key triple DES EDE in ECB mode des-ede-cfb Two key triple DES EDE in CFB mode des-ede-ofb Two key triple DES EDE in OFB mode des-ede3-cbc Three key triple DES EDE in CBC mode des-ede3 Three key triple DES EDE in ECB mode des3 Alias for des-ede3-cbc des-ede3-cfb Three key triple DES EDE CFB mode des-ede3-ofb Three key triple DES EDE in OFB mode desx DESX algorithm. gost89 GOST 28147-89 in CFB mode (provided by ccgost engine) gost89-cnt `GOST 28147-89 in CNT mode (provided by ccgost engine) idea-cbc IDEA algorithm in CBC mode idea same as idea-cbc idea-cfb IDEA in CFB mode idea-ecb IDEA in ECB mode idea-ofb IDEA in OFB mode rc2-cbc 128 bit RC2 in CBC mode rc2 Alias for rc2-cbc rc2-cfb 128 bit RC2 in CFB mode rc2-ecb 128 bit RC2 in ECB mode rc2-ofb 128 bit RC2 in OFB mode rc2-64-cbc 64 bit RC2 in CBC mode rc2-40-cbc 40 bit RC2 in CBC mode rc4 128 bit RC4 rc4-64 64 bit RC4 rc4-40 40 bit RC4 rc5-cbc RC5 cipher in CBC mode rc5 Alias for rc5-cbc rc5-cfb RC5 cipher in CFB mode rc5-ecb RC5 cipher in ECB mode rc5-ofb RC5 cipher in OFB mode seed-cbc SEED cipher in CBC mode seed Alias for seed-cbc seed-cfb SEED cipher in CFB mode seed-ecb SEED cipher in ECB mode seed-ofb SEED cipher in OFB mode sm4-cbc SM4 cipher in CBC mode sm4 Alias for sm4-cbc sm4-cfb SM4 cipher in CFB mode sm4-ctr SM4 cipher in CTR mode sm4-ecb SM4 cipher in ECB mode sm4-ofb SM4 cipher in OFB mode aes-[128|192|256]-cbc 128/192/256 bit AES in CBC mode aes[128|192|256] Alias for aes-[128|192|256]-cbc aes-[128|192|256]-cfb 128/192/256 bit AES in 128 bit CFB mode aes-[128|192|256]-cfb1 128/192/256 bit AES in 1 bit CFB mode aes-[128|192|256]-cfb8 128/192/256 bit AES in 8 bit CFB mode aes-[128|192|256]-ctr 128/192/256 bit AES in CTR mode aes-[128|192|256]-ecb 128/192/256 bit AES in ECB mode aes-[128|192|256]-ofb 128/192/256 bit AES in OFB mode aria-[128|192|256]-cbc 128/192/256 bit ARIA in CBC mode aria[128|192|256] Alias for aria-[128|192|256]-cbc aria-[128|192|256]-cfb 128/192/256 bit ARIA in 128 bit CFB mode aria-[128|192|256]-cfb1 128/192/256 bit ARIA in 1 bit CFB mode aria-[128|192|256]-cfb8 128/192/256 bit ARIA in 8 bit CFB mode aria-[128|192|256]-ctr 128/192/256 bit ARIA in CTR mode aria-[128|192|256]-ecb 128/192/256 bit ARIA in ECB mode aria-[128|192|256]-ofb 128/192/256 bit ARIA in OFB mode camellia-[128|192|256]-cbc 128/192/256 bit Camellia in CBC mode camellia[128|192|256] Alias for camellia-[128|192|256]-cbc camellia-[128|192|256]-cfb 128/192/256 bit Camellia in 128 bit CFB mode camellia-[128|192|256]-cfb1 128/192/256 bit Camellia in 1 bit CFB mode camellia-[128|192|256]-cfb8 128/192/256 bit Camellia in 8 bit CFB mode camellia-[128|192|256]-ctr 128/192/256 bit Camellia in CTR mode camellia-[128|192|256]-ecb 128/192/256 bit Camellia in ECB mode camellia-[128|192|256]-ofb 128/192/256 bit Camellia in OFB mode</code></pre> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Just base64 encode a binary file:</p> <pre><code> openssl base64 -in file.bin -out file.b64</code></pre> <p>Decode the same file</p> <pre><code> openssl base64 -d -in file.b64 -out file.bin</code></pre> <p>Encrypt a file using AES-128 using a prompted password and PBKDF2 key derivation:</p> <pre><code> openssl enc -aes128 -pbkdf2 -in file.txt -out file.aes128</code></pre> <p>Decrypt a file using a supplied password:</p> <pre><code> openssl enc -aes128 -pbkdf2 -d -in file.aes128 -out file.txt \ -pass pass:<password></code></pre> <p>Encrypt a file then base64 encode it (so it can be sent via mail for example) using AES-256 in CTR mode and PBKDF2 key derivation:</p> <pre><code> openssl enc -aes-256-ctr -pbkdf2 -a -in file.txt -out file.aes256</code></pre> <p>Base64 decode a file then decrypt it using a password supplied in a file:</p> <pre><code> openssl enc -aes-256-ctr -pbkdf2 -d -a -in file.aes256 -out file.txt \ -pass file:<passfile></code></pre> <h1 id="BUGS">BUGS</h1> <p>The <b>-A</b> option when used with large files doesn't work properly.</p> <p>The <b>enc</b> program only supports a fixed number of algorithms with certain parameters.

A TSA can be part of a PKI deployment and its role is to provide long term proof of the existence of a certain datum before a particular time. Here is a brief description of the protocol:</p> <ol> <li><p>The TSA client computes a one-way hash value for a data file and sends the hash to the TSA.</p> </li> <li><p>The TSA attaches the current date and time to the received hash value, signs them and sends the timestamp token back to the client. By creating this token the TSA certifies the existence of the original data file at the time of response generation.</p> </li> <li><p>The TSA client receives the timestamp token and verifies the signature on it.

The user is prompted to enter the filename of the CA certificates (which should also contain the private key) or by hitting ENTER details of the CA will be prompted for. The relevant files and directories are created in a directory called "demoCA" in the current directory. <b>openssl req</b> and <b>openssl ca</b> commands are get invoked.</p> </dd> <dt id="pkcs12"><b>-pkcs12</b></dt> <dd> <p>Create a PKCS#12 file containing the user certificate, private key and CA certificate. It expects the user certificate and private key to be in the file "newcert.pem" and the CA certificate to be in the file demoCA/cacert.pem, it creates a file "newcert.p12". This command can thus be called after the <b>-sign</b> option. The PKCS#12 file can be imported directly into a browser. If there is an additional argument on the command line it will be used as the "friendly name" for the certificate (which is typically displayed in the browser list box), otherwise the name "My Certificate" is used. Delegates work to <b>openssl pkcs12</b> command.</p> </dd> <dt id="sign--signcert--xsign"><b>-sign</b>, <b>-signcert</b>, <b>-xsign</b></dt> <dd> <p>Calls the <b>ca</b> program to sign a certificate request. It expects the request to be in the file "newreq.pem". The new certificate is written to the file "newcert.pem" except in the case of the <b>-xsign</b> option when it is written to standard output. Leverages <b>openssl ca</b> command.</p> </dd> <dt id="signCA"><b>-signCA</b></dt> <dd> <p>This option is the same as the <b>-sign</b> option except it uses the configuration file section <b>v3_ca</b> and so makes the signed request a valid CA certificate.

This can happen if a previous call using the <b>-newca</b> option terminated abnormally. To get the correct behaviour delete the demoCA directory if it already exists.</p> <p>Under some environments it may not be possible to run the <b>CA.pl</b> script directly (for example Win32) and the default configuration file location may be wrong. In this case the command:</p> <pre><code> perl -S CA.pl</code></pre> <p>can be used and the <b>OPENSSL_CONF</b> environment variable changed to point to the correct path of the configuration file.</p> <p>The script is intended as a simple front end for the <b>openssl</b> program for use by a beginner. Its behaviour isn't always what is wanted.

Thus, despite the text of RFC7671, name checks are by default enabled for DANE-EE(3) TLSA records, and can be disabled in applications where it is safe to do so.

To connect to an SSL HTTP server the command:</p> <pre><code> openssl s_client -connect servername:443</code></pre> <p>would typically be used (https uses port 443). If the connection succeeds then an HTTP command can be given such as "GET /" to retrieve a web page.</p> <p>If the handshake fails then there are several possible causes, if it is nothing obvious like no client certificate then the <b>-bugs</b>, <b>-ssl3</b>, <b>-tls1</b>, <b>-no_ssl3</b>, <b>-no_tls1</b> options can be tried in case it is a buggy server. In particular you should play with these options <b>before</b> submitting a bug report to an OpenSSL mailing list.</p> <p>A frequent problem when attempting to get client certificates working is that a web client complains it has no certificates or gives an empty list to choose from. This is normally because the server is not sending the clients certificate authority in its "acceptable CA list" when it requests a certificate. By using <b>s_client</b> the CA list can be viewed and checked. However, some servers only request client authentication after a specific URL is requested. To obtain the list in this case it is necessary to use the <b>-prexit</b> option and send an HTTP request for an appropriate page.</p> <p>If a certificate is specified on the command line using the <b>-cert</b> option it will not be used unless the server specifically requests a client certificate. Therefore, merely including a client certificate on the command line is no guarantee that the certificate works.</p> <p>If there are problems verifying a server certificate then the <b>-showcerts</b> option can be used to show all the certificates sent by the server.</p> <p>The <b>s_client</b> utility is a test tool and is designed to continue the handshake after any certificate verification errors. As a result it will accept any certificate chain (trusted or not) sent by the peer. Non-test applications should <b>not</b> do this as it makes them vulnerable to a MITM attack. This behaviour can be changed by with the <b>-verify_return_error</b> option: any verify errors are then returned aborting the handshake.</p> <p>The <b>-bind</b> option may be useful if the server or a firewall requires connections to come from some particular address and or port.</p> <h1 id="BUGS">BUGS</h1> <p>Because this program has a lot of options and also because some of the techniques used are rather old, the C source of <b>s_client</b> is rather hard to read and not a model of how things should be done. A typical SSL client program would be much simpler.</p> <p>The <b>-prexit</b> option is a bit of a hack. We should really report information whenever a session is renegotiated.</p> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man3/SSL_CONF_cmd.html">SSL_CONF_cmd(3)</a>, <a href="../man1/sess_id.html">sess_id(1)</a>, <a href="../man1/s_server.html">s_server(1)</a>, <a href="../man1/ciphers.html">ciphers(1)</a>, <a href="../man3/SSL_CTX_set_max_send_fragment.html">SSL_CTX_set_max_send_fragment(3)</a>, <a href="../man3/SSL_CTX_set_split_send_fragment.html">SSL_CTX_set_split_send_fragment(3)</a>, <a href="../man3/SSL_CTX_set_max_pipelines.html">SSL_CTX_set_max_pipelines(3)</a></p> <h1 id="HISTORY">HISTORY</h1> <p>The <b>-no_alt_chains</b> option was added in OpenSSL 1.1.0.

This allows all the problems with a certificate chain to be determined.</p> <p>The verify operation consists of a number of separate steps.</p> <p>Firstly a certificate chain is built up starting from the supplied certificate and ending in the root CA. It is an error if the whole chain cannot be built up. The chain is built up by looking up the issuers certificate of the current certificate. If a certificate is found which is its own issuer it is assumed to be the root CA.</p> <p>The process of 'looking up the issuers certificate' itself involves a number of steps. After all certificates whose subject name matches the issuer name of the current certificate are subject to further tests. The relevant authority key identifier components of the current certificate (if present) must match the subject key identifier (if present) and issuer and serial number of the candidate issuer, in addition the keyUsage extension of the candidate issuer (if present) must permit certificate signing.</p> <p>The lookup first looks in the list of untrusted certificates and if no match is found the remaining lookups are from the trusted certificates. The root CA is always looked up in the trusted certificate list: if the certificate to verify is a root certificate then an exact match must be found in the trusted list.</p> <p>The second operation is to check every untrusted certificate's extensions for consistency with the supplied purpose. If the <b>-purpose</b> option is not included then no checks are done. The supplied or "leaf" certificate must have extensions compatible with the supplied purpose and all other certificates must also be valid CA certificates. The precise extensions required are described in more detail in the <b>CERTIFICATE EXTENSIONS</b> section of the <b>x509</b> utility.</p> <p>The third operation is to check the trust settings on the root CA. The root CA should be trusted for the supplied purpose. For compatibility with previous versions of OpenSSL, a certificate with no trust settings is considered to be valid for all purposes.</p> <p>The final operation is to check the validity of the certificate chain. For each element in the chain, including the root CA certificate, the validity period as specified by the <code>notBefore</code> and <code>notAfter</code> fields is checked against the current system time. The <b>-attime</b> flag may be used to use a reference time other than "now." The certificate signature is checked as well (except for the signature of the typically self-signed root CA certificate, which is verified only if the <b>-check_ss_sig</b> option is given).</p> <p>If all operations complete successfully then certificate is considered valid. If any operation fails then the certificate is not valid.</p> <h1 id="DIAGNOSTICS">DIAGNOSTICS</h1> <p>When a verify operation fails the output messages can be somewhat cryptic. The general form of the error message is:</p> <pre><code> server.pem: /C=AU/ST=Queensland/O=CryptSoft Pty Ltd/CN=Test CA (1024 bit) error 24 at 1 depth lookup:invalid CA certificate</code></pre> <p>The first line contains the name of the certificate being verified followed by the subject name of the certificate. The second line contains the error number and the depth. The depth is number of the certificate being verified when a problem was detected starting with zero for the certificate being verified itself then 1 for the CA that signed the certificate and so on. Finally a text version of the error number is presented.</p> <p>A partial list of the error codes and messages is shown below, this also includes the name of the error code as defined in the header file x509_vfy.h Some of the error codes are defined but never returned: these are described as "unused".</p> <dl> <dt id="X509_V_OK"><b>X509_V_OK</b></dt> <dd> <p>The operation was successful.</p> </dd> <dt id="X509_V_ERR_UNSPECIFIED"><b>X509_V_ERR_UNSPECIFIED</b></dt> <dd> <p>Unspecified error; should not happen.</p> </dd> <dt id="X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT"><b>X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT</b></dt> <dd> <p>The issuer certificate of a looked up certificate could not be found.

There is no guarantee that the first certificate present is the one corresponding to the private key. Certain software which requires a private key and certificate and assumes the first certificate in the file is the one corresponding to the private key: this may not always be the case. Using the <b>-clcerts</b> option will solve this problem by only outputting the certificate corresponding to the private key. If the CA certificates are required then they can be output to a separate file using the <b>-nokeys -cacerts</b> options to just output CA certificates.</p> <p>The <b>-keypbe</b> and <b>-certpbe</b> algorithms allow the precise encryption algorithms for private keys and certificates to be specified. Normally the defaults are fine but occasionally software can't handle triple DES encrypted private keys, then the option <b>-keypbe PBE-SHA1-RC2-40</b> can be used to reduce the private key encryption to 40 bit RC2. A complete description of all algorithms is contained in the <b>pkcs8</b> manual page.</p> <p>Prior 1.1 release passwords containing non-ASCII characters were encoded in non-compliant manner, which limited interoperability, in first hand with Windows. But switching to standard-compliant password encoding poses problem accessing old data protected with broken encoding. For this reason even legacy encodings is attempted when reading the data. If you use PKCS#12 files in production application you are advised to convert the data, because implemented heuristic approach is not MT-safe, its sole goal is to facilitate the data upgrade with this utility.</p> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Parse a PKCS#12 file and output it to a file:</p> <pre><code> openssl pkcs12 -in file.p12 -out file.pem</code></pre> <p>Output only client certificates to a file:</p> <pre><code> openssl pkcs12 -in file.p12 -clcerts -out file.pem</code></pre> <p>Don't encrypt the private key:</p> <pre><code> openssl pkcs12 -in file.p12 -out file.pem -nodes</code></pre> <p>Print some info about a PKCS#12 file:</p> <pre><code> openssl pkcs12 -in file.p12 -info -noout</code></pre> <p>Create a PKCS#12 file:</p> <pre><code> openssl pkcs12 -export -in file.pem -out file.p12 -name "My Certificate"</code></pre> <p>Include some extra certificates:</p> <pre><code> openssl pkcs12 -export -in file.pem -out file.p12 -name "My Certificate" \ -certfile othercerts.pem</code></pre> <h1 id="SEE-ALSO">SEE ALSO</h1> <p><a href="../man1/pkcs8.html">pkcs8(1)</a></p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2021 The OpenSSL Project Authors.

A \s-1DRBG\s0 is a certain type of cryptographically-secure pseudo-random number generator (\s-1CSPRNG\s0), which is described in [\s-1NIST SP 800\-90A\s0 Rev. 1]. .PP While the \s-1RAND API\s0 is the 'frontend' which is intended to be used by application developers for obtaining random bytes, the \s-1RAND_DRBG API\s0 serves as the 'backend', connecting the former with the operating systems's entropy sources and providing access to the \s-1DRBG\s0's configuration parameters. .SS "Disclaimer" .IX Subsection "Disclaimer" Unless you have very specific requirements for your random generator, it is in general not necessary to utilize the \s-1RAND_DRBG API\s0 directly. The usual way to obtain random bytes is to use \fBRAND_bytes\fR\|(3) or \&\fBRAND_priv_bytes\fR\|(3), see also \s-1\fBRAND\s0\fR\|(7). .SS "Typical Use Cases" .IX Subsection "Typical Use Cases" Typical examples for such special use cases are the following: .IP "\(bu" 2 You want to use your own private \s-1DRBG\s0 instances. Multiple \s-1DRBG\s0 instances which are accessed only by a single thread provide additional security (because their internal states are independent) and better scalability in multithreaded applications (because they don't need to be locked). .IP "\(bu" 2 You need to integrate a previously unsupported entropy source. .IP "\(bu" 2 You need to change the default settings of the standard OpenSSL \s-1RAND\s0 implementation to meet specific requirements. .SH "CHAINING" .IX Header "CHAINING" A \s-1DRBG\s0 instance can be used as the entropy source of another \s-1DRBG\s0 instance, provided it has itself access to a valid entropy source. The \s-1DRBG\s0 instance which acts as entropy source is called the \fIparent\fR \s-1DRBG,\s0 the other instance the \fIchild\fR \s-1DRBG.\s0 .PP This is called chaining. A chained \s-1DRBG\s0 instance is created by passing a pointer to the parent \s-1DRBG\s0 as argument to the \fBRAND_DRBG_new()\fR call. It is possible to create chains of more than two \s-1DRBG\s0 in a row. .SH "THE THREE SHARED DRBG INSTANCES" .IX Header "THE THREE SHARED DRBG INSTANCES" Currently, there are three shared \s-1DRBG\s0 instances, the <master>, <public>, and <private> \s-1DRBG.\s0 While the <master> \s-1DRBG\s0 is a single global instance, the <public> and <private> \&\s-1DRBG\s0 are created per thread and accessed through thread-local storage. .PP By default, the functions \fBRAND_bytes\fR\|(3) and \fBRAND_priv_bytes\fR\|(3) use the thread-local <public> and <private> \s-1DRBG\s0 instance, respectively. .SS "The <master> \s-1DRBG\s0 instance" .IX Subsection "The <master> DRBG instance" The <master> \s-1DRBG\s0 is not used directly by the application, only for reseeding the two other two \s-1DRBG\s0 instances. It reseeds itself by obtaining randomness either from os entropy sources or by consuming randomness which was added previously by \fBRAND_add\fR\|(3). .SS "The <public> \s-1DRBG\s0 instance" .IX Subsection "The <public> DRBG instance" This instance is used per default by \fBRAND_bytes\fR\|(3). .SS "The <private> \s-1DRBG\s0 instance" .IX Subsection "The <private> DRBG instance" This instance is used per default by \fBRAND_priv_bytes\fR\|(3) .SH "LOCKING" .IX Header "LOCKING" The <master> \s-1DRBG\s0 is intended to be accessed concurrently for reseeding by its child \s-1DRBG\s0 instances. The necessary locking is done internally. It is \fInot\fR thread-safe to access the <master> \s-1DRBG\s0 directly via the \&\s-1RAND_DRBG\s0 interface. The <public> and <private> \s-1DRBG\s0 are thread-local, i.e. there is an instance of each per thread. So they can safely be accessed without locking via the \s-1RAND_DRBG\s0 interface. .PP Pointers to these \s-1DRBG\s0 instances can be obtained using \&\fBRAND_DRBG_get0_master()\fR, \&\fBRAND_DRBG_get0_public()\fR, and \&\fBRAND_DRBG_get0_private()\fR, respectively. Note that it is not allowed to store a pointer to one of the thread-local \&\s-1DRBG\s0 instances in a variable or other memory location where it will be accessed and used by multiple threads. .PP All other \s-1DRBG\s0 instances created by an application don't support locking, because they are intended to be used by a single thread. Instead of accessing a single \s-1DRBG\s0 instance concurrently from different threads, it is recommended to instantiate a separate \s-1DRBG\s0 instance per thread. Using the <master> \s-1DRBG\s0 as entropy source for multiple \s-1DRBG\s0 instances on different threads is thread-safe, because the \s-1DRBG\s0 instance will lock the <master> \s-1DRBG\s0 automatically for obtaining random input. .SH "THE OVERALL PICTURE" .IX Header "THE OVERALL PICTURE" The following picture gives an overview over how the \s-1DRBG\s0 instances work together and are being used. .PP .Vb 10 \& +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& | os entropy sources | \& +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& | \& v +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& RAND_add() ==> <master> <\-| shared DRBG (with locking) | \& / \e +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& / \e +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& <public> <private> <\- | per\-thread DRBG instances | \& | | +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& v v \& RAND_bytes() RAND_priv_bytes() \& | ^ \& | | \& +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ \& | general purpose | | used for secrets like session keys | \& | random generator | | and private keys for certificates | \& +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+ .Ve .PP The usual way to obtain random bytes is to call RAND_bytes(...) or RAND_priv_bytes(...). These calls are roughly equivalent to calling RAND_DRBG_bytes(<public>, ...) and RAND_DRBG_bytes(<private>, ...), respectively. The method \fBRAND_DRBG_bytes\fR\|(3) is a convenience method wrapping the \fBRAND_DRBG_generate\fR\|(3) function, which serves the actual request for random data. .SH "RESEEDING" .IX Header "RESEEDING" A \s-1DRBG\s0 instance seeds itself automatically, pulling random input from its entropy source. The entropy source can be either a trusted operating system entropy source, or another \s-1DRBG\s0 with access to such a source. .PP Automatic reseeding occurs after a predefined number of generate requests. The selection of the trusted entropy sources is configured at build time using the \-\-with\-rand\-seed option. The following sections explain the reseeding process in more detail. .SS "Automatic Reseeding" .IX Subsection "Automatic Reseeding" Before satisfying a generate request (\fBRAND_DRBG_generate\fR\|(3)), the \s-1DRBG\s0 reseeds itself automatically, if one of the following conditions holds: .PP \&\- the \s-1DRBG\s0 was not instantiated (=seeded) yet or has been uninstantiated. .PP \&\- the number of generate requests since the last reseeding exceeds a certain threshold, the so called \fIreseed_interval\fR. This behaviour can be disabled by setting the \fIreseed_interval\fR to 0. .PP \&\- the time elapsed since the last reseeding exceeds a certain time interval, the so called \fIreseed_time_interval\fR. This can be disabled by setting the \fIreseed_time_interval\fR to 0. .PP \&\- the \s-1DRBG\s0 is in an error state. .PP \&\fBNote\fR: An error state is entered if the entropy source fails while the \s-1DRBG\s0 is seeding or reseeding. The last case ensures that the \s-1DRBG\s0 automatically recovers from the error as soon as the entropy source is available again. .SS "Manual Reseeding" .IX Subsection "Manual Reseeding" In addition to automatic reseeding, the caller can request an immediate reseeding of the \s-1DRBG\s0 with fresh entropy by setting the \&\fIprediction resistance\fR parameter to 1 when calling \fBRAND_DRBG_generate\fR\|(3). .PP The document [\s-1NIST SP 800\-90C\s0] describes prediction resistance requests in detail and imposes strict conditions on the entropy sources that are approved for providing prediction resistance. Since the default \s-1DRBG\s0 implementation does not have access to such an approved entropy source, a request for prediction resistance will currently always fail. In other words, prediction resistance is currently not supported yet by the \s-1DRBG.\s0 .PP For the three shared DRBGs (and only for these) there is another way to reseed them manually: If \fBRAND_add\fR\|(3) is called with a positive \fIrandomness\fR argument (or \fBRAND_seed\fR\|(3)), then this will immediately reseed the <master> \s-1DRBG.\s0 The <public> and <private> \s-1DRBG\s0 will detect this on their next generate call and reseed, pulling randomness from <master>. .PP The last feature has been added to support the common practice used with previous OpenSSL versions to call \fBRAND_add()\fR before calling \fBRAND_bytes()\fR. .SS "Entropy Input vs. Additional Data" .IX Subsection "Entropy Input vs. Additional Data" The \s-1DRBG\s0 distinguishes two different types of random input: \fIentropy\fR, which comes from a trusted source, and \fIadditional input\fR', which can optionally be added by the user and is considered untrusted. It is possible to add \fIadditional input\fR not only during reseeding, but also for every generate request. This is in fact done automatically by \fBRAND_DRBG_bytes\fR\|(3). .SS "Configuring the Random Seed Source" .IX Subsection "Configuring the Random Seed Source" In most cases OpenSSL will automatically choose a suitable seed source for automatically seeding and reseeding its <master> \s-1DRBG.\s0 In some cases however, it will be necessary to explicitly specify a seed source during configuration, using the \-\-with\-rand\-seed option. For more information, see the \s-1INSTALL\s0 instructions. There are also operating systems where no seed source is available and automatic reseeding is disabled by default. .PP The following two sections describe the reseeding process of the master \&\s-1DRBG,\s0 depending on whether automatic reseeding is available or not. .SS "Reseeding the master \s-1DRBG\s0 with automatic seeding enabled" .IX Subsection "Reseeding the master DRBG with automatic seeding enabled" Calling \fBRAND_poll()\fR or \fBRAND_add()\fR is not necessary, because the \s-1DRBG\s0 pulls the necessary entropy from its source automatically. However, both calls are permitted, and do reseed the \s-1RNG.\s0 .PP \&\fBRAND_add()\fR can be used to add both kinds of random input, depending on the value of the \fBrandomness\fR argument: .IP "randomness == 0:" 4 .IX Item "randomness == 0:" The random bytes are mixed as additional input into the current state of the \s-1DRBG.\s0 Mixing in additional input is not considered a full reseeding, hence the reseed counter is not reset. .IP "randomness > 0:" 4 .IX Item "randomness > 0:" The random bytes are used as entropy input for a full reseeding (resp. reinstantiation) if the \s-1DRBG\s0 is instantiated (resp. uninstantiated or in an error state). The number of random bits required for reseeding is determined by the security strength of the \s-1DRBG.\s0 Currently it defaults to 256 bits (32 bytes). It is possible to provide less randomness than required. In this case the missing randomness will be obtained by pulling random input from the trusted entropy sources. .SS "Reseeding the master \s-1DRBG\s0 with automatic seeding disabled" .IX Subsection "Reseeding the master DRBG with automatic seeding disabled" Calling \fBRAND_poll()\fR will always fail. .PP \&\fBRAND_add()\fR needs to be called for initial seeding and periodic reseeding. At least 48 bytes (384 bits) of randomness have to be provided, otherwise the (re\-)seeding of the \s-1DRBG\s0 will fail. This corresponds to one and a half times the security strength of the \s-1DRBG.\s0 The extra half is used for the nonce during instantiation. .PP More precisely, the number of bytes needed for seeding depend on the \&\fIsecurity strength\fR of the \s-1DRBG,\s0 which is set to 256 by default. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBRAND_DRBG_bytes\fR\|(3), \&\fBRAND_DRBG_generate\fR\|(3), \&\fBRAND_DRBG_reseed\fR\|(3), \&\fBRAND_DRBG_get0_master\fR\|(3), \&\fBRAND_DRBG_get0_public\fR\|(3), \&\fBRAND_DRBG_get0_private\fR\|(3), \&\fBRAND_DRBG_set_reseed_interval\fR\|(3), \&\fBRAND_DRBG_set_reseed_time_interval\fR\|(3), \&\fBRAND_DRBG_set_reseed_defaults\fR\|(3), \&\s-1\fBRAND\s0\fR\|(7), .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2017\-2018 The OpenSSL Project Authors.

The services provided by this library are used by the OpenSSL implementations of \s-1SSL, TLS\s0 and S/MIME, and they have also been used to implement \s-1SSH,\s0 OpenPGP, and other cryptographic standards. .PP \&\fBlibcrypto\fR consists of a number of sub-libraries that implement the individual algorithms. .PP The functionality includes symmetric encryption, public key cryptography and key agreement, certificate handling, cryptographic hash functions, cryptographic pseudo-random number generator, and various utilities. .SH "NOTES" .IX Header "NOTES" Some of the newer functions follow a naming convention using the numbers \&\fB0\fR and \fB1\fR. For example the functions: .PP .Vb 2 \& int X509_CRL_add0_revoked(X509_CRL *crl, X509_REVOKED *rev); \& int X509_add1_trust_object(X509 *x, const ASN1_OBJECT *obj); .Ve .PP The \fB0\fR version uses the supplied structure pointer directly in the parent and it will be freed up when the parent is freed. In the above example \fBcrl\fR would be freed but \fBrev\fR would not. .PP The \fB1\fR function uses a copy of the supplied structure pointer (or in some cases increases its link count) in the parent and so both (\fBx\fR and \fBobj\fR above) should be freed up. .SH "RETURN VALUES" .IX Header "RETURN VALUES" See the individual manual pages for details. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBopenssl\fR\|(1), \fBssl\fR\|(7) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2016 The OpenSSL Project Authors.

The current implementation in OpenSSL supports both signature and encryption schemes via the \s-1EVP\s0 interface. .PP When doing the \fB\s-1SM2\s0\fR signature algorithm, it requires a distinguishing identifier to form the message prefix which is hashed before the real message is hashed. .SH "NOTES" .IX Header "NOTES" \&\fB\s-1SM2\s0\fR signatures can be generated by using the 'DigestSign' series of APIs, for instance, \fBEVP_DigestSignInit()\fR, \fBEVP_DigestSignUpdate()\fR and \fBEVP_DigestSignFinal()\fR. Ditto for the verification process by calling the 'DigestVerify' series of APIs. .PP There are several special steps that need to be done before computing an \fB\s-1SM2\s0\fR signature. .PP The \fB\s-1EVP_PKEY\s0\fR structure will default to using \s-1ECDSA\s0 for signatures when it is created. It should be set to \fB\s-1EVP_PKEY_SM2\s0\fR by calling: .PP .Vb 1 \& EVP_PKEY_set_alias_type(pkey, EVP_PKEY_SM2); .Ve .PP Then an \s-1ID\s0 should be set by calling: .PP .Vb 1 \& EVP_PKEY_CTX_set1_id(pctx, id, id_len); .Ve .PP When calling the \fBEVP_DigestSignInit()\fR or \fBEVP_DigestVerifyInit()\fR functions, a preallocated \fB\s-1EVP_PKEY_CTX\s0\fR should be assigned to the \fB\s-1EVP_MD_CTX\s0\fR. This is done by calling: .PP .Vb 1 \& EVP_MD_CTX_set_pkey_ctx(mctx, pctx); .Ve .PP And normally there is no need to pass a \fBpctx\fR parameter to \fBEVP_DigestSignInit()\fR or \fBEVP_DigestVerifyInit()\fR in such a scenario. .SH "EXAMPLES" .IX Header "EXAMPLES" This example demonstrates the calling sequence for using an \fB\s-1EVP_PKEY\s0\fR to verify a message with the \s-1SM2\s0 signature algorithm and the \s-1SM3\s0 hash algorithm: .PP .Vb 1 \& #include <openssl/evp.h> \& \& /* obtain an EVP_PKEY using whatever methods... */ \& EVP_PKEY_set_alias_type(pkey, EVP_PKEY_SM2); \& mctx = EVP_MD_CTX_new(); \& pctx = EVP_PKEY_CTX_new(pkey, NULL); \& EVP_PKEY_CTX_set1_id(pctx, id, id_len); \& EVP_MD_CTX_set_pkey_ctx(mctx, pctx);; \& EVP_DigestVerifyInit(mctx, NULL, EVP_sm3(), NULL, pkey); \& EVP_DigestVerifyUpdate(mctx, msg, msg_len); \& EVP_DigestVerifyFinal(mctx, sig, sig_len) .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_PKEY_CTX_new\fR\|(3), \&\fBEVP_PKEY_set_alias_type\fR\|(3), \&\fBEVP_DigestSignInit\fR\|(3), \&\fBEVP_DigestVerifyInit\fR\|(3), \&\fBEVP_PKEY_CTX_set1_id\fR\|(3), \&\fBEVP_MD_CTX_set_pkey_ctx\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2018\-2020 The OpenSSL Project Authors.

Be aware that \fBdes_cbc_encrypt()\fR is not really \s-1DES CBC\s0 (it does not update the \s-1IV\s0); use \fBdes_ncbc_encrypt()\fR instead. .IP "\(bu" 2 a multiple of 64 bits are enciphered at a time. .IP "\(bu" 2 The \s-1CBC\s0 mode produces the same ciphertext whenever the same plaintext is encrypted using the same key and starting variable. .IP "\(bu" 2 The chaining operation makes the ciphertext blocks dependent on the current and all preceding plaintext blocks and therefore blocks can not be rearranged. .IP "\(bu" 2 The use of different starting variables prevents the same plaintext enciphering to the same ciphertext. .IP "\(bu" 2 An error will affect the current and the following ciphertext blocks. .SS "Cipher Feedback Mode (\s-1CFB\s0)" .IX Subsection "Cipher Feedback Mode (CFB)" Normally, this is found as the function \fIalgorithm\fR\fB_cfb_encrypt()\fR. .IP "\(bu" 2 a number of bits (j) <= 64 are enciphered at a time. .IP "\(bu" 2 The \s-1CFB\s0 mode produces the same ciphertext whenever the same plaintext is encrypted using the same key and starting variable. .IP "\(bu" 2 The chaining operation makes the ciphertext variables dependent on the current and all preceding variables and therefore j\-bit variables are chained together and can not be rearranged. .IP "\(bu" 2 The use of different starting variables prevents the same plaintext enciphering to the same ciphertext. .IP "\(bu" 2 The strength of the \s-1CFB\s0 mode depends on the size of k (maximal if j == k). In my implementation this is always the case. .IP "\(bu" 2 Selection of a small value for j will require more cycles through the encipherment algorithm per unit of plaintext and thus cause greater processing overheads. .IP "\(bu" 2 Only multiples of j bits can be enciphered. .IP "\(bu" 2 An error will affect the current and the following ciphertext variables. .SS "Output Feedback Mode (\s-1OFB\s0)" .IX Subsection "Output Feedback Mode (OFB)" Normally, this is found as the function \fIalgorithm\fR\fB_ofb_encrypt()\fR. .IP "\(bu" 2 a number of bits (j) <= 64 are enciphered at a time. .IP "\(bu" 2 The \s-1OFB\s0 mode produces the same ciphertext whenever the same plaintext enciphered using the same key and starting variable. More over, in the \s-1OFB\s0 mode the same key stream is produced when the same key and start variable are used. Consequently, for security reasons a specific start variable should be used only once for a given key. .IP "\(bu" 2 The absence of chaining makes the \s-1OFB\s0 more vulnerable to specific attacks. .IP "\(bu" 2 The use of different start variables values prevents the same plaintext enciphering to the same ciphertext, by producing different key streams. .IP "\(bu" 2 Selection of a small value for j will require more cycles through the encipherment algorithm per unit of plaintext and thus cause greater processing overheads. .IP "\(bu" 2 Only multiples of j bits can be enciphered. .IP "\(bu" 2 \&\s-1OFB\s0 mode of operation does not extend ciphertext errors in the resultant plaintext output. Every bit error in the ciphertext causes only one bit to be in error in the deciphered plaintext. .IP "\(bu" 2 \&\s-1OFB\s0 mode is not self-synchronizing. If the two operation of encipherment and decipherment get out of synchronism, the system needs to be re-initialized. .IP "\(bu" 2 Each re-initialization should use a value of the start variable different from the start variable values used before with the same key. The reason for this is that an identical bit stream would be produced each time from the same parameters. This would be susceptible to a 'known plaintext' attack. .SS "Triple \s-1ECB\s0 Mode" .IX Subsection "Triple ECB Mode" Normally, this is found as the function \fIalgorithm\fR\fB_ecb3_encrypt()\fR. .IP "\(bu" 2 Encrypt with key1, decrypt with key2 and encrypt with key3 again. .IP "\(bu" 2 As for \s-1ECB\s0 encryption but increases the key length to 168 bits. There are theoretic attacks that can be used that make the effective key length 112 bits, but this attack also requires 2^56 blocks of memory, not very likely, even for the \s-1NSA.\s0 .IP "\(bu" 2 If both keys are the same it is equivalent to encrypting once with just one key. .IP "\(bu" 2 If the first and last key are the same, the key length is 112 bits. There are attacks that could reduce the effective key strength to only slightly more than 56 bits, but these require a lot of memory. .IP "\(bu" 2 If all 3 keys are the same, this is effectively the same as normal ecb mode. .SS "Triple \s-1CBC\s0 Mode" .IX Subsection "Triple CBC Mode" Normally, this is found as the function \fIalgorithm\fR\fB_ede3_cbc_encrypt()\fR. .IP "\(bu" 2 Encrypt with key1, decrypt with key2 and then encrypt with key3. .IP "\(bu" 2 As for \s-1CBC\s0 encryption but increases the key length to 168 bits with the same restrictions as for triple ecb mode. .SH "NOTES" .IX Header "NOTES" This text was been written in large parts by Eric Young in his original documentation for SSLeay, the predecessor of OpenSSL.

If an application uses a \s-1BIO\s0 for its I/O it can transparently handle \s-1SSL\s0 connections, unencrypted network connections and file I/O. .PP There are two type of \s-1BIO,\s0 a source/sink \s-1BIO\s0 and a filter \s-1BIO.\s0 .PP As its name implies a source/sink \s-1BIO\s0 is a source and/or sink of data, examples include a socket \s-1BIO\s0 and a file \s-1BIO.\s0 .PP A filter \s-1BIO\s0 takes data from one \s-1BIO\s0 and passes it through to another, or the application. The data may be left unmodified (for example a message digest \s-1BIO\s0) or translated (for example an encryption \s-1BIO\s0). The effect of a filter \s-1BIO\s0 may change according to the I/O operation it is performing: for example an encryption \&\s-1BIO\s0 will encrypt data if it is being written to and decrypt data if it is being read from. .PP BIOs can be joined together to form a chain (a single \s-1BIO\s0 is a chain with one component). A chain normally consist of one source/sink \&\s-1BIO\s0 and one or more filter BIOs. Data read from or written to the first \s-1BIO\s0 then traverses the chain to the end (normally a source/sink \&\s-1BIO\s0). .PP Some BIOs (such as memory BIOs) can be used immediately after calling \&\fBBIO_new()\fR. Others (such as file BIOs) need some additional initialization, and frequently a utility function exists to create and initialize such BIOs. .PP If \fBBIO_free()\fR is called on a \s-1BIO\s0 chain it will only free one \s-1BIO\s0 resulting in a memory leak. .PP Calling \fBBIO_free_all()\fR on a single \s-1BIO\s0 has the same effect as calling \&\fBBIO_free()\fR on it other than the discarded return value. .PP Normally the \fBtype\fR argument is supplied by a function which returns a pointer to a \s-1BIO_METHOD.\s0 There is a naming convention for such functions: a source/sink \s-1BIO\s0 is normally called BIO_s_*() and a filter \s-1BIO\s0 BIO_f_*(); .SH "EXAMPLES" .IX Header "EXAMPLES" Create a memory \s-1BIO:\s0 .PP .Vb 1 \& BIO *mem = BIO_new(BIO_s_mem()); .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBBIO_ctrl\fR\|(3), \&\fBBIO_f_base64\fR\|(3), \fBBIO_f_buffer\fR\|(3), \&\fBBIO_f_cipher\fR\|(3), \fBBIO_f_md\fR\|(3), \&\fBBIO_f_null\fR\|(3), \fBBIO_f_ssl\fR\|(3), \&\fBBIO_find_type\fR\|(3), \fBBIO_new\fR\|(3), \&\fBBIO_new_bio_pair\fR\|(3), \&\fBBIO_push\fR\|(3), \fBBIO_read_ex\fR\|(3), \&\fBBIO_s_accept\fR\|(3), \fBBIO_s_bio\fR\|(3), \&\fBBIO_s_connect\fR\|(3), \fBBIO_s_fd\fR\|(3), \&\fBBIO_s_file\fR\|(3), \fBBIO_s_mem\fR\|(3), \&\fBBIO_s_null\fR\|(3), \fBBIO_s_socket\fR\|(3), \&\fBBIO_set_callback\fR\|(3), \&\fBBIO_should_retry\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2019 The OpenSSL Project Authors.

This manual page attempts to give an overview over how this problem is currently addressed in different parts of the OpenSSL library. .SS "The general case" .IX Subsection "The general case" The OpenSSL library doesn't treat pass phrases in any special way as a general rule, and trusts the application or user to choose a suitable character set and stick to that throughout the lifetime of affected objects. This means that for an object that was encrypted using a pass phrase encoded in \&\s-1ISO\-8859\-1,\s0 that object needs to be decrypted using a pass phrase encoded in \&\s-1ISO\-8859\-1.\s0 Using the wrong encoding is expected to cause a decryption failure. .SS "PKCS#12" .IX Subsection "PKCS#12" PKCS#12 is a bit different regarding pass phrase encoding. The standard stipulates that the pass phrase shall be encoded as an \s-1ASN.1\s0 BMPString, which consists of the code points of the basic multilingual plane, encoded in big endian (\s-1UCS\-2 BE\s0). .PP OpenSSL tries to adapt to this requirements in one of the following manners: .IP "1." 4 Treats the received pass phrase as \s-1UTF\-8\s0 encoded and tries to re-encode it to \&\s-1UTF\-16\s0 (which is the same as \s-1UCS\-2\s0 for characters U+0000 to U+D7FF and U+E000 to U+FFFF, but becomes an expansion for any other character), or failing that, proceeds with step 2. .IP "2." 4 Assumes that the pass phrase is encoded in \s-1ASCII\s0 or \s-1ISO\-8859\-1\s0 and opportunistically prepends each byte with a zero byte to obtain the \s-1UCS\-2\s0 encoding of the characters, which it stores as a BMPString. .Sp Note that since there is no check of your locale, this may produce \s-1UCS\-2 / UTF\-16\s0 characters that do not correspond to the original pass phrase characters for other character sets, such as any \s-1ISO\-8859\-X\s0 encoding other than \&\s-1ISO\-8859\-1\s0 (or for Windows, \s-1CP 1252\s0 with exception for the extra \*(L"graphical\*(R" characters in the 0x80\-0x9F range). .PP OpenSSL versions older than 1.1.0 do variant 2 only, and that is the reason why OpenSSL still does this, to be able to read files produced with older versions. .PP It should be noted that this approach isn't entirely fault free. .PP A pass phrase encoded in \s-1ISO\-8859\-2\s0 could very well have a sequence such as 0xC3 0xAF (which is the two characters \*(L"\s-1LATIN CAPITAL LETTER A WITH BREVE\*(R"\s0 and \*(L"\s-1LATIN CAPITAL LETTER Z WITH DOT ABOVE\*(R"\s0 in \s-1ISO\-8859\-2\s0 encoding), but would be misinterpreted as the perfectly valid \s-1UTF\-8\s0 encoded code point U+00EF (\s-1LATIN SMALL LETTER I WITH DIAERESIS\s0) \fIif the pass phrase doesn't contain anything that would be invalid \s-1UTF\-8\s0\fR. A pass phrase that contains this kind of byte sequence will give a different outcome in OpenSSL 1.1.0 and newer than in OpenSSL older than 1.1.0. .PP .Vb 2 \& 0x00 0xC3 0x00 0xAF # OpenSSL older than 1.1.0 \& 0x00 0xEF # OpenSSL 1.1.0 and newer .Ve .PP On the same accord, anything encoded in \s-1UTF\-8\s0 that was given to OpenSSL older than 1.1.0 was misinterpreted as \s-1ISO\-8859\-1\s0 sequences. .SS "\s-1OSSL_STORE\s0" .IX Subsection "OSSL_STORE" \&\fBossl_store\fR\|(7) acts as a general interface to access all kinds of objects, potentially protected with a pass phrase, a \s-1PIN\s0 or something else. This \s-1API\s0 stipulates that pass phrases should be \s-1UTF\-8\s0 encoded, and that any other pass phrase encoding may give undefined results. This \s-1API\s0 relies on the application to ensure \s-1UTF\-8\s0 encoding, and doesn't check that this is the case, so what it gets, it will also pass to the underlying loader. .SH "RECOMMENDATIONS" .IX Header "RECOMMENDATIONS" This section assumes that you know what pass phrase was used for encryption, but that it may have been encoded in a different character encoding than the one used by your current input method. For example, the pass phrase may have been used at a time when your default encoding was \s-1ISO\-8859\-1\s0 (i.e. \*(L"nai\*:ve\*(R" resulting in the byte sequence 0x6E 0x61 0xEF 0x76 0x65), and you're now in an environment where your default encoding is \s-1UTF\-8\s0 (i.e. \*(L"nai\*:ve\*(R" resulting in the byte sequence 0x6E 0x61 0xC3 0xAF 0x76 0x65). Whenever it's mentioned that you should use a certain character encoding, it should be understood that you either change the input method to use the mentioned encoding when you type in your pass phrase, or use some suitable tool to convert your pass phrase from your default encoding to the target encoding. .PP Also note that the sub-sections below discuss human readable pass phrases. This is particularly relevant for PKCS#12 objects, where human readable pass phrases are assumed. For other objects, it's as legitimate to use any byte sequence (such as a sequence of bytes from `/dev/urandom` that's been saved away), which makes any character encoding discussion irrelevant; in such cases, simply use the same byte sequence as it is. .SS "Creating new objects" .IX Subsection "Creating new objects" For creating new pass phrase protected objects, make sure the pass phrase is encoded using \s-1UTF\-8.\s0 This is default on most modern Unixes, but may involve an effort on other platforms. Specifically for Windows, setting the environment variable \&\f(CW\*(C`OPENSSL_WIN32_UTF8\*(C'\fR will have anything entered on [Windows] console prompt converted to \s-1UTF\-8\s0 (command line and separately prompted pass phrases alike). .SS "Opening existing objects" .IX Subsection "Opening existing objects" For opening pass phrase protected objects where you know what character encoding was used for the encryption pass phrase, make sure to use the same encoding again. .PP For opening pass phrase protected objects where the character encoding that was used is unknown, or where the producing application is unknown, try one of the following: .IP "1." 4 Try the pass phrase that you have as it is in the character encoding of your environment. It's possible that its byte sequence is exactly right. .IP "2." 4 Convert the pass phrase to \s-1UTF\-8\s0 and try with the result. Specifically with PKCS#12, this should open up any object that was created according to the specification. .IP "3." 4 Do a nai\*:ve (i.e. purely mathematical) \s-1ISO\-8859\-1\s0 to \s-1UTF\-8\s0 conversion and try with the result. This differs from the previous attempt because \s-1ISO\-8859\-1\s0 maps directly to U+0000 to U+00FF, which other non\-UTF\-8 character sets do not. .Sp This also takes care of the case when a \s-1UTF\-8\s0 encoded string was used with OpenSSL older than 1.1.0. (for example, \f(CW\*(C`i\*:\*(C'\fR, which is 0xC3 0xAF when encoded in \s-1UTF\-8,\s0 would become 0xC3 0x83 0xC2 0xAF when re-encoded in the nai\*:ve manner. The conversion to BMPString would then yield 0x00 0xC3 0x00 0xA4 0x00 0x00, the erroneous/non\-compliant encoding used by OpenSSL older than 1.1.0) .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBevp\fR\|(7), \&\fBossl_store\fR\|(7), \&\fBEVP_BytesToKey\fR\|(3), \fBEVP_DecryptInit\fR\|(3), \&\fBPEM_do_header\fR\|(3), \&\fBPKCS12_parse\fR\|(3), \fBPKCS12_newpass\fR\|(3), \&\fBd2i_PKCS8PrivateKey_bio\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2018\-2020 The OpenSSL Project Authors.

The intention of this is to render brute forcing of passwords on systems that lack large amounts of main memory (such as GPUs or ASICs) computationally infeasible. .PP scrypt provides three work factors that can be customized: N, r and p. N, which has to be a positive power of two, is the general work factor and scales \s-1CPU\s0 time in an approximately linear fashion. r is the block size of the internally used hash function and p is the parallelization factor. Both r and p need to be greater than zero. The amount of \s-1RAM\s0 that scrypt requires for its computation is roughly (128 * N * r * p) bytes. .PP In the original paper of Colin Percival (\*(L"Stronger Key Derivation via Sequential Memory-Hard Functions\*(R", 2009), the suggested values that give a computation time of less than 5 seconds on a 2.5 GHz Intel Core 2 Duo are N = 2^20 = 1048576, r = 8, p = 1. Consequently, the required amount of memory for this computation is roughly 1 GiB. On a more recent \s-1CPU\s0 (Intel i7\-5930K at 3.5 GHz), this computation takes about 3 seconds. When N, r or p are not specified, they default to 1048576, 8, and 1, respectively. The default amount of \s-1RAM\s0 that may be used by scrypt defaults to 1025 MiB. .SH "NOTES" .IX Header "NOTES" A context for scrypt can be obtained by calling: .PP .Vb 1 \& EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_SCRYPT, NULL); .Ve .PP The output length of an scrypt key derivation is specified via the length parameter to the \fBEVP_PKEY_derive\fR\|(3) function. .SH "EXAMPLES" .IX Header "EXAMPLES" This example derives a 64\-byte long test vector using scrypt using the password \&\*(L"password\*(R", salt \*(L"NaCl\*(R" and N = 1024, r = 8, p = 16. .PP .Vb 2 \& EVP_PKEY_CTX *pctx; \& unsigned char out[64]; \& \& size_t outlen = sizeof(out); \& pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_SCRYPT, NULL); \& \& if (EVP_PKEY_derive_init(pctx) <= 0) { \& error("EVP_PKEY_derive_init"); \& } \& if (EVP_PKEY_CTX_set1_pbe_pass(pctx, "password", 8) <= 0) { \& error("EVP_PKEY_CTX_set1_pbe_pass"); \& } \& if (EVP_PKEY_CTX_set1_scrypt_salt(pctx, "NaCl", 4) <= 0) { \& error("EVP_PKEY_CTX_set1_scrypt_salt"); \& } \& if (EVP_PKEY_CTX_set_scrypt_N(pctx, 1024) <= 0) { \& error("EVP_PKEY_CTX_set_scrypt_N"); \& } \& if (EVP_PKEY_CTX_set_scrypt_r(pctx, 8) <= 0) { \& error("EVP_PKEY_CTX_set_scrypt_r"); \& } \& if (EVP_PKEY_CTX_set_scrypt_p(pctx, 16) <= 0) { \& error("EVP_PKEY_CTX_set_scrypt_p"); \& } \& if (EVP_PKEY_derive(pctx, out, &outlen) <= 0) { \& error("EVP_PKEY_derive"); \& } \& \& { \& const unsigned char expected[sizeof(out)] = { \& 0xfd, 0xba, 0xbe, 0x1c, 0x9d, 0x34, 0x72, 0x00, \& 0x78, 0x56, 0xe7, 0x19, 0x0d, 0x01, 0xe9, 0xfe, \& 0x7c, 0x6a, 0xd7, 0xcb, 0xc8, 0x23, 0x78, 0x30, \& 0xe7, 0x73, 0x76, 0x63, 0x4b, 0x37, 0x31, 0x62, \& 0x2e, 0xaf, 0x30, 0xd9, 0x2e, 0x22, 0xa3, 0x88, \& 0x6f, 0xf1, 0x09, 0x27, 0x9d, 0x98, 0x30, 0xda, \& 0xc7, 0x27, 0xaf, 0xb9, 0x4a, 0x83, 0xee, 0x6d, \& 0x83, 0x60, 0xcb, 0xdf, 0xa2, 0xcc, 0x06, 0x40 \& }; \& \& assert(!memcmp(out, expected, sizeof(out))); \& } \& \& EVP_PKEY_CTX_free(pctx); .Ve .SH "CONFORMING TO" .IX Header "CONFORMING TO" \&\s-1RFC 7914\s0 .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_PKEY_CTX_set1_scrypt_salt\fR\|(3), \&\fBEVP_PKEY_CTX_set_scrypt_N\fR\|(3), \&\fBEVP_PKEY_CTX_set_scrypt_r\fR\|(3), \&\fBEVP_PKEY_CTX_set_scrypt_p\fR\|(3), \&\fBEVP_PKEY_CTX_set_scrypt_maxmem_bytes\fR\|(3), \&\fBEVP_PKEY_CTX_new\fR\|(3), \&\fBEVP_PKEY_CTX_ctrl_str\fR\|(3), \&\fBEVP_PKEY_derive\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2017\-2019 The OpenSSL Project Authors.

Software-based generators must be seeded with external randomness before they can be used as a cryptographically-secure pseudo-random number generator (\s-1CSPRNG\s0). The availability of common hardware with special instructions and modern operating systems, which may use items such as interrupt jitter and network packet timings, can be reasonable sources of seeding material. .PP OpenSSL comes with a default implementation of the \s-1RAND API\s0 which is based on the deterministic random bit generator (\s-1DRBG\s0) model as described in [\s-1NIST SP 800\-90A\s0 Rev. 1]. The default random generator will initialize automatically on first use and will be fully functional without having to be initialized ('seeded') explicitly. It seeds and reseeds itself automatically using trusted random sources provided by the operating system. .PP As a normal application developer, you do not have to worry about any details, just use \fBRAND_bytes\fR\|(3) to obtain random data. Having said that, there is one important rule to obey: Always check the error return value of \fBRAND_bytes\fR\|(3) and do not take randomness for granted. Although (re\-)seeding is automatic, it can fail because no trusted random source is available or the trusted source(s) temporarily fail to provide sufficient random seed material. In this case the \s-1CSPRNG\s0 enters an error state and ceases to provide output, until it is able to recover from the error by reseeding itself. For more details on reseeding and error recovery, see \s-1\fBRAND_DRBG\s0\fR\|(7). .PP For values that should remain secret, you can use \fBRAND_priv_bytes\fR\|(3) instead. This method does not provide 'better' randomness, it uses the same type of \s-1CSPRNG.\s0 The intention behind using a dedicated \s-1CSPRNG\s0 exclusively for private values is that none of its output should be visible to an attacker (e.g., used as salt value), in order to reveal as little information as possible about its internal state, and that a compromise of the \*(L"public\*(R" \&\s-1CSPRNG\s0 instance will not affect the secrecy of these private values. .PP In the rare case where the default implementation does not satisfy your special requirements, there are two options: .IP "\(bu" 2 Replace the default \s-1RAND\s0 method by your own \s-1RAND\s0 method using \&\fBRAND_set_rand_method\fR\|(3). .IP "\(bu" 2 Modify the default settings of the OpenSSL \s-1RAND\s0 method by modifying the security parameters of the underlying \s-1DRBG,\s0 which is described in detail in \s-1\fBRAND_DRBG\s0\fR\|(7). .PP Changing the default random generator or its default parameters should be necessary only in exceptional cases and is not recommended, unless you have a profound knowledge of cryptographic principles and understand the implications of your changes. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBRAND_add\fR\|(3), \&\fBRAND_bytes\fR\|(3), \&\fBRAND_priv_bytes\fR\|(3), \&\fBRAND_get_rand_method\fR\|(3), \&\fBRAND_set_rand_method\fR\|(3), \&\fBRAND_OpenSSL\fR\|(3), \&\s-1\fBRAND_DRBG\s0\fR\|(7) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2018\-2019 The OpenSSL Project Authors.

This function should be called after all operations using a cipher are complete so sensitive information does not remain in memory. .PP \&\fBEVP_EncryptInit_ex()\fR sets up cipher context \fBctx\fR for encryption with cipher \fBtype\fR from \s-1ENGINE\s0 \fBimpl\fR. \fBctx\fR must be created before calling this function. \fBtype\fR is normally supplied by a function such as \fBEVP_aes_256_cbc()\fR. If \fBimpl\fR is \s-1NULL\s0 then the default implementation is used. \fBkey\fR is the symmetric key to use and \fBiv\fR is the \s-1IV\s0 to use (if necessary), the actual number of bytes used for the key and \s-1IV\s0 depends on the cipher. It is possible to set all parameters to \s-1NULL\s0 except \fBtype\fR in an initial call and supply the remaining parameters in subsequent calls, all of which have \fBtype\fR set to \s-1NULL.\s0 This is done when the default cipher parameters are not appropriate. .PP \&\fBEVP_EncryptUpdate()\fR encrypts \fBinl\fR bytes from the buffer \fBin\fR and writes the encrypted version to \fBout\fR. This function can be called multiple times to encrypt successive blocks of data. The amount of data written depends on the block alignment of the encrypted data. For most ciphers and modes, the amount of data written can be anything from zero bytes to (inl + cipher_block_size \- 1) bytes. For wrap cipher modes, the amount of data written can be anything from zero bytes to (inl + cipher_block_size) bytes. For stream ciphers, the amount of data written can be anything from zero bytes to inl bytes. Thus, \fBout\fR should contain sufficient room for the operation being performed. The actual number of bytes written is placed in \fBoutl\fR. It also checks if \fBin\fR and \fBout\fR are partially overlapping, and if they are 0 is returned to indicate failure. .PP If padding is enabled (the default) then \fBEVP_EncryptFinal_ex()\fR encrypts the \*(L"final\*(R" data, that is any data that remains in a partial block. It uses standard block padding (aka \s-1PKCS\s0 padding) as described in the \s-1NOTES\s0 section, below. The encrypted final data is written to \fBout\fR which should have sufficient space for one cipher block. The number of bytes written is placed in \fBoutl\fR. After this function is called the encryption operation is finished and no further calls to \fBEVP_EncryptUpdate()\fR should be made. .PP If padding is disabled then \fBEVP_EncryptFinal_ex()\fR will not encrypt any more data and it will return an error if any data remains in a partial block: that is if the total data length is not a multiple of the block size. .PP \&\fBEVP_DecryptInit_ex()\fR, \fBEVP_DecryptUpdate()\fR and \fBEVP_DecryptFinal_ex()\fR are the corresponding decryption operations. \fBEVP_DecryptFinal()\fR will return an error code if padding is enabled and the final block is not correctly formatted. The parameters and restrictions are identical to the encryption operations except that if padding is enabled the decrypted data buffer \fBout\fR passed to \fBEVP_DecryptUpdate()\fR should have sufficient room for (\fBinl\fR + cipher_block_size) bytes unless the cipher block size is 1 in which case \fBinl\fR bytes is sufficient. .PP \&\fBEVP_CipherInit_ex()\fR, \fBEVP_CipherUpdate()\fR and \fBEVP_CipherFinal_ex()\fR are functions that can be used for decryption or encryption. The operation performed depends on the value of the \fBenc\fR parameter. It should be set to 1 for encryption, 0 for decryption and \-1 to leave the value unchanged (the actual value of 'enc' being supplied in a previous call). .PP \&\fBEVP_CIPHER_CTX_reset()\fR clears all information from a cipher context and free up any allocated memory associate with it, except the \fBctx\fR itself. This function should be called anytime \fBctx\fR is to be reused for another \fBEVP_CipherInit()\fR / \fBEVP_CipherUpdate()\fR / \fBEVP_CipherFinal()\fR series of calls. .PP \&\fBEVP_EncryptInit()\fR, \fBEVP_DecryptInit()\fR and \fBEVP_CipherInit()\fR behave in a similar way to \fBEVP_EncryptInit_ex()\fR, \fBEVP_DecryptInit_ex()\fR and \&\fBEVP_CipherInit_ex()\fR except they always use the default cipher implementation. .PP \&\fBEVP_EncryptFinal()\fR, \fBEVP_DecryptFinal()\fR and \fBEVP_CipherFinal()\fR are identical to \fBEVP_EncryptFinal_ex()\fR, \fBEVP_DecryptFinal_ex()\fR and \&\fBEVP_CipherFinal_ex()\fR. In previous releases they also cleaned up the \fBctx\fR, but this is no longer done and \fBEVP_CIPHER_CTX_clean()\fR must be called to free any context resources. .PP \&\fBEVP_get_cipherbyname()\fR, \fBEVP_get_cipherbynid()\fR and \fBEVP_get_cipherbyobj()\fR return an \s-1EVP_CIPHER\s0 structure when passed a cipher name, a \s-1NID\s0 or an \&\s-1ASN1_OBJECT\s0 structure. .PP \&\fBEVP_CIPHER_nid()\fR and \fBEVP_CIPHER_CTX_nid()\fR return the \s-1NID\s0 of a cipher when passed an \fB\s-1EVP_CIPHER\s0\fR or \fB\s-1EVP_CIPHER_CTX\s0\fR structure. The actual \s-1NID\s0 value is an internal value which may not have a corresponding \s-1OBJECT IDENTIFIER.\s0 .PP \&\fBEVP_CIPHER_CTX_set_padding()\fR enables or disables padding. This function should be called after the context is set up for encryption or decryption with \fBEVP_EncryptInit_ex()\fR, \fBEVP_DecryptInit_ex()\fR or \&\fBEVP_CipherInit_ex()\fR. By default encryption operations are padded using standard block padding and the padding is checked and removed when decrypting. If the \fBpad\fR parameter is zero then no padding is performed, the total amount of data encrypted or decrypted must then be a multiple of the block size or an error will occur. .PP \&\fBEVP_CIPHER_key_length()\fR and \fBEVP_CIPHER_CTX_key_length()\fR return the key length of a cipher when passed an \fB\s-1EVP_CIPHER\s0\fR or \fB\s-1EVP_CIPHER_CTX\s0\fR structure. The constant \fB\s-1EVP_MAX_KEY_LENGTH\s0\fR is the maximum key length for all ciphers. Note: although \fBEVP_CIPHER_key_length()\fR is fixed for a given cipher, the value of \fBEVP_CIPHER_CTX_key_length()\fR may be different for variable key length ciphers. .PP \&\fBEVP_CIPHER_CTX_set_key_length()\fR sets the key length of the cipher ctx. If the cipher is a fixed length cipher then attempting to set the key length to any value other than the fixed value is an error. .PP \&\fBEVP_CIPHER_iv_length()\fR and \fBEVP_CIPHER_CTX_iv_length()\fR return the \s-1IV\s0 length of a cipher when passed an \fB\s-1EVP_CIPHER\s0\fR or \fB\s-1EVP_CIPHER_CTX\s0\fR.

Padding is always added so if the data is already a multiple of the block size \fBn\fR will equal the block size. For example if the block size is 8 and 11 bytes are to be encrypted then 5 padding bytes of value 5 will be added. .PP When decrypting the final block is checked to see if it has the correct form. .PP Although the decryption operation can produce an error if padding is enabled, it is not a strong test that the input data or key is correct. A random block has better than 1 in 256 chance of being of the correct format and problems with the input data earlier on will not produce a final decrypt error. .PP If padding is disabled then the decryption operation will always succeed if the total amount of data decrypted is a multiple of the block size. .PP The functions \fBEVP_EncryptInit()\fR, \fBEVP_EncryptFinal()\fR, \fBEVP_DecryptInit()\fR, \&\fBEVP_CipherInit()\fR and \fBEVP_CipherFinal()\fR are obsolete but are retained for compatibility with existing code.

As a consequence, \fBEVP_CipherInit()\fR does not allow step-by-step initialization of the ctx when the \fIkey\fR and \fIiv\fR are passed in separate calls. It also means that the flags set for the \s-1CTX\s0 are removed, and it is especially important for the \&\fB\s-1EVP_CIPHER_CTX_FLAG_WRAP_ALLOW\s0\fR flag treated specially in \&\fBEVP_CipherInit_ex()\fR. .PP \&\fBEVP_get_cipherbynid()\fR, and \fBEVP_get_cipherbyobj()\fR are implemented as macros. .SH "BUGS" .IX Header "BUGS" \&\fB\s-1EVP_MAX_KEY_LENGTH\s0\fR and \fB\s-1EVP_MAX_IV_LENGTH\s0\fR only refer to the internal ciphers with default key lengths.

It signals that the error of reason code \fBreason\fR occurred in function \&\fBfunc\fR of library \fBlib\fR, in line number \fBline\fR of \fBfile\fR. This function is usually called by a macro. .PP \&\fBERR_add_error_data()\fR associates the concatenation of its \fBnum\fR string arguments with the error code added last. \&\fBERR_add_error_vdata()\fR is similar except the argument is a \fBva_list\fR. .PP \&\fBERR_load_strings\fR\|(3) can be used to register error strings so that the application can a generate human-readable error messages for the error code. .SS "Reporting errors" .IX Subsection "Reporting errors" Each sub-library has a specific macro \fBXXXerr()\fR that is used to report errors. Its first argument is a function code \fB\s-1XXX_F_...\s0\fR, the second argument is a reason code \fB\s-1XXX_R_...\s0\fR. Function codes are derived from the function names; reason codes consist of textual error descriptions. For example, the function \fBssl3_read_bytes()\fR reports a \&\*(L"handshake failure\*(R" as follows: .PP .Vb 1 \& SSLerr(SSL_F_SSL3_READ_BYTES, SSL_R_SSL_HANDSHAKE_FAILURE); .Ve .PP Function and reason codes should consist of uppercase characters, numbers and underscores only. The error file generation script translates function codes into function names by looking in the header files for an appropriate function name, if none is found it just uses the capitalized form such as \*(L"\s-1SSL3_READ_BYTES\*(R"\s0 in the above example. .PP The trailing section of a reason code (after the \*(L"_R_\*(R") is translated into lowercase and underscores changed to spaces. .PP Although a library will normally report errors using its own specific XXXerr macro, another library's macro can be used. This is normally only done when a library wants to include \s-1ASN1\s0 code which must use the \fBASN1err()\fR macro. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBERR_put_error()\fR and \fBERR_add_error_data()\fR return no values. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBERR_load_strings\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

If no callback function shall be specified, the \s-1NULL\s0 pointer can be used for \fBverify_callback\fR. In this case last \fBverify_callback\fR set specifically for this \fBssl\fR remains. If no special \fBcallback\fR was set before, the default callback for the underlying \&\fBctx\fR is used, that was valid at the time \fBssl\fR was created with \&\fBSSL_new\fR\|(3). Within the callback function, \&\fBSSL_get_ex_data_X509_STORE_CTX_idx\fR can be called to get the data index of the current \s-1SSL\s0 object that is doing the verification. .PP \&\fBSSL_CTX_set_verify_depth()\fR sets the maximum \fBdepth\fR for the certificate chain verification that shall be allowed for \fBctx\fR. .PP \&\fBSSL_set_verify_depth()\fR sets the maximum \fBdepth\fR for the certificate chain verification that shall be allowed for \fBssl\fR. .PP \&\fBSSL_CTX_set_post_handshake_auth()\fR and \fBSSL_set_post_handshake_auth()\fR enable the Post-Handshake Authentication extension to be added to the ClientHello such that post-handshake authentication can be requested by the server. If \fBval\fR is 0 then the extension is not sent, otherwise it is. By default the extension is not sent. A certificate callback will need to be set via \&\fBSSL_CTX_set_client_cert_cb()\fR if no certificate is provided at initialization. .PP \&\fBSSL_verify_client_post_handshake()\fR causes a CertificateRequest message to be sent by a server on the given \fBssl\fR connection. The \s-1SSL_VERIFY_PEER\s0 flag must be set; the \s-1SSL_VERIFY_POST_HANDSHAKE\s0 flag is optional. .SH "NOTES" .IX Header "NOTES" The verification of certificates can be controlled by a set of logically or'ed \fBmode\fR flags: .IP "\s-1SSL_VERIFY_NONE\s0" 4 .IX Item "SSL_VERIFY_NONE" \&\fBServer mode:\fR the server will not send a client certificate request to the client, so the client will not send a certificate. .Sp \&\fBClient mode:\fR if not using an anonymous cipher (by default disabled), the server will send a certificate which will be checked. The result of the certificate verification process can be checked after the \s-1TLS/SSL\s0 handshake using the \fBSSL_get_verify_result\fR\|(3) function. The handshake will be continued regardless of the verification result. .IP "\s-1SSL_VERIFY_PEER\s0" 4 .IX Item "SSL_VERIFY_PEER" \&\fBServer mode:\fR the server sends a client certificate request to the client. The certificate returned (if any) is checked. If the verification process fails, the \s-1TLS/SSL\s0 handshake is immediately terminated with an alert message containing the reason for the verification failure. The behaviour can be controlled by the additional \&\s-1SSL_VERIFY_FAIL_IF_NO_PEER_CERT, SSL_VERIFY_CLIENT_ONCE\s0 and \&\s-1SSL_VERIFY_POST_HANDSHAKE\s0 flags. .Sp \&\fBClient mode:\fR the server certificate is verified. If the verification process fails, the \s-1TLS/SSL\s0 handshake is immediately terminated with an alert message containing the reason for the verification failure. If no server certificate is sent, because an anonymous cipher is used, \s-1SSL_VERIFY_PEER\s0 is ignored. .IP "\s-1SSL_VERIFY_FAIL_IF_NO_PEER_CERT\s0" 4 .IX Item "SSL_VERIFY_FAIL_IF_NO_PEER_CERT" \&\fBServer mode:\fR if the client did not return a certificate, the \s-1TLS/SSL\s0 handshake is immediately terminated with a \*(L"handshake failure\*(R" alert. This flag must be used together with \s-1SSL_VERIFY_PEER.\s0 .Sp \&\fBClient mode:\fR ignored (see \s-1BUGS\s0) .IP "\s-1SSL_VERIFY_CLIENT_ONCE\s0" 4 .IX Item "SSL_VERIFY_CLIENT_ONCE" \&\fBServer mode:\fR only request a client certificate once during the connection. Do not ask for a client certificate again during renegotiation or post-authentication if a certificate was requested during the initial handshake. This flag must be used together with \&\s-1SSL_VERIFY_PEER.\s0 .Sp \&\fBClient mode:\fR ignored (see \s-1BUGS\s0) .IP "\s-1SSL_VERIFY_POST_HANDSHAKE\s0" 4 .IX Item "SSL_VERIFY_POST_HANDSHAKE" \&\fBServer mode:\fR the server will not send a client certificate request during the initial handshake, but will send the request via \&\fBSSL_verify_client_post_handshake()\fR. This allows the \s-1SSL_CTX\s0 or \s-1SSL\s0 to be configured for post-handshake peer verification before the handshake occurs. This flag must be used together with \&\s-1SSL_VERIFY_PEER.\s0 TLSv1.3 only; no effect on pre\-TLSv1.3 connections. .Sp \&\fBClient mode:\fR ignored (see \s-1BUGS\s0) .PP If the \fBmode\fR is \s-1SSL_VERIFY_NONE\s0 none of the other flags may be set. .PP The actual verification procedure is performed either using the built-in verification procedure or using another application provided verification function set with \&\fBSSL_CTX_set_cert_verify_callback\fR\|(3). The following descriptions apply in the case of the built-in procedure. An application provided procedure also has access to the verify depth information and the \fBverify_callback()\fR function, but the way this information is used may be different. .PP \&\fBSSL_CTX_set_verify_depth()\fR and \fBSSL_set_verify_depth()\fR set a limit on the number of certificates between the end-entity and trust-anchor certificates. Neither the end-entity nor the trust-anchor certificates count against \fBdepth\fR. If the certificate chain needed to reach a trusted issuer is longer than \fBdepth+2\fR, X509_V_ERR_CERT_CHAIN_TOO_LONG will be issued. The depth count is \*(L"level 0:peer certificate\*(R", \*(L"level 1: \s-1CA\s0 certificate\*(R", \&\*(L"level 2: higher level \s-1CA\s0 certificate\*(R", and so on. Setting the maximum depth to 2 allows the levels 0, 1, 2 and 3 (0 being the end-entity and 3 the trust-anchor). The default depth limit is 100, allowing for the peer certificate, at most 100 intermediate \s-1CA\s0 certificates and a final trust anchor certificate. .PP The \fBverify_callback\fR function is used to control the behaviour when the \&\s-1SSL_VERIFY_PEER\s0 flag is set. It must be supplied by the application and receives two arguments: \fBpreverify_ok\fR indicates, whether the verification of the certificate in question was passed (preverify_ok=1) or not (preverify_ok=0). \fBx509_ctx\fR is a pointer to the complete context used for the certificate chain verification. .PP The certificate chain is checked starting with the deepest nesting level (the root \s-1CA\s0 certificate) and worked upward to the peer's certificate. At each level signatures and issuer attributes are checked. Whenever a verification error is found, the error number is stored in \fBx509_ctx\fR and \fBverify_callback\fR is called with \fBpreverify_ok\fR=0. By applying X509_CTX_store_* functions \fBverify_callback\fR can locate the certificate in question and perform additional steps (see \s-1EXAMPLES\s0). If no error is found for a certificate, \fBverify_callback\fR is called with \fBpreverify_ok\fR=1 before advancing to the next level. .PP The return value of \fBverify_callback\fR controls the strategy of the further verification process. If \fBverify_callback\fR returns 0, the verification process is immediately stopped with \*(L"verification failed\*(R" state. If \&\s-1SSL_VERIFY_PEER\s0 is set, a verification failure alert is sent to the peer and the \s-1TLS/SSL\s0 handshake is terminated. If \fBverify_callback\fR returns 1, the verification process is continued. If \fBverify_callback\fR always returns 1, the \s-1TLS/SSL\s0 handshake will not be terminated with respect to verification failures and the connection will be established. The calling process can however retrieve the error code of the last verification error using \&\fBSSL_get_verify_result\fR\|(3) or by maintaining its own error storage managed by \fBverify_callback\fR. .PP If no \fBverify_callback\fR is specified, the default callback will be used. Its return value is identical to \fBpreverify_ok\fR, so that any verification failure will lead to a termination of the \s-1TLS/SSL\s0 handshake with an alert message, if \s-1SSL_VERIFY_PEER\s0 is set. .PP After calling \fBSSL_set_post_handshake_auth()\fR, the client will need to add a certificate or certificate callback to its configuration before it can successfully authenticate. This must be called before \fBSSL_connect()\fR. .PP \&\fBSSL_verify_client_post_handshake()\fR requires that verify flags have been previously set, and that a client sent the post-handshake authentication extension. When the client returns a certificate the verify callback will be invoked. A write operation must take place for the Certificate Request to be sent to the client, this can be done with \fBSSL_do_handshake()\fR or \fBSSL_write_ex()\fR. Only one certificate request may be outstanding at any time. .PP When post-handshake authentication occurs, a refreshed NewSessionTicket message is sent to the client. .SH "BUGS" .IX Header "BUGS" In client mode, it is not checked whether the \s-1SSL_VERIFY_PEER\s0 flag is set, but whether any flags other than \s-1SSL_VERIFY_NONE\s0 are set. This can lead to unexpected behaviour if \s-1SSL_VERIFY_PEER\s0 and other flags are not used as required. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The SSL*_set_verify*() functions do not provide diagnostic information. .PP The \fBSSL_verify_client_post_handshake()\fR function returns 1 if the request succeeded, and 0 if the request failed. The error stack can be examined to determine the failure reason. .SH "EXAMPLES" .IX Header "EXAMPLES" The following code sequence realizes an example \fBverify_callback\fR function that will always continue the \s-1TLS/SSL\s0 handshake regardless of verification failure, if wished. The callback realizes a verification depth limit with more informational output. .PP All verification errors are printed; information about the certificate chain is printed on request. The example is realized for a server that does allow but not require client certificates. .PP The example makes use of the ex_data technique to store application data into/retrieve application data from the \s-1SSL\s0 structure (see \fBCRYPTO_get_ex_new_index\fR\|(3), \&\fBSSL_get_ex_data_X509_STORE_CTX_idx\fR\|(3)). .PP .Vb 7 \& ... \& typedef struct { \& int verbose_mode; \& int verify_depth; \& int always_continue; \& } mydata_t; \& int mydata_index; \& \& ... \& static int verify_callback(int preverify_ok, X509_STORE_CTX *ctx) \& { \& char buf[256]; \& X509 *err_cert; \& int err, depth; \& SSL *ssl; \& mydata_t *mydata; \& \& err_cert = X509_STORE_CTX_get_current_cert(ctx); \& err = X509_STORE_CTX_get_error(ctx); \& depth = X509_STORE_CTX_get_error_depth(ctx); \& \& /* \& * Retrieve the pointer to the SSL of the connection currently treated \& * and the application specific data stored into the SSL object. \& */ \& ssl = X509_STORE_CTX_get_ex_data(ctx, SSL_get_ex_data_X509_STORE_CTX_idx()); \& mydata = SSL_get_ex_data(ssl, mydata_index); \& \& X509_NAME_oneline(X509_get_subject_name(err_cert), buf, 256); \& \& /* \& * Catch a too long certificate chain.

If \fBmaxline\fR is zero a default value of 4k is used. The \s-1OCSP\s0 request \fBreq\fR may be set to \fB\s-1NULL\s0\fR and provided later if required. .PP \&\fBOCSP_sendreq_nbio()\fR performs nonblocking I/O on the \s-1OCSP\s0 request context \&\fBrctx\fR. When the operation is complete it returns the response in \fB*presp\fR. .PP \&\fBOCSP_REQ_CTX_free()\fR frees up the \s-1OCSP\s0 context \fBrctx\fR. .PP \&\fBOCSP_set_max_response_length()\fR sets the maximum response length for \fBrctx\fR to \fBlen\fR. If the response exceeds this length an error occurs. If not set a default value of 100k is used. .PP \&\fBOCSP_REQ_CTX_add1_header()\fR adds header \fBname\fR with value \fBvalue\fR to the context \fBrctx\fR. It can be called more than once to add multiple headers. It \fB\s-1MUST\s0\fR be called before any calls to \fBOCSP_sendreq_nbio()\fR. The \fBreq\fR parameter in the initial to \fBOCSP_sendreq_new()\fR call \s-1MUST\s0 be set to \fB\s-1NULL\s0\fR if additional headers are set. .PP \&\fBOCSP_REQ_CTX_set1_req()\fR sets the \s-1OCSP\s0 request in \fBrctx\fR to \fBreq\fR. This function should be called after any calls to \fBOCSP_REQ_CTX_add1_header()\fR. OCSP_REQ_CTX_set1_req(rctx, req) is equivalent to the following: .PP .Vb 2 \& OCSP_REQ_CTX_i2d(rctx, "application/ocsp\-request", \& ASN1_ITEM_rptr(OCSP_REQUEST), (ASN1_VALUE *)req) .Ve .PP \&\fBOCSP_REQ_CTX_i2d()\fR sets the request context \fBrctx\fR to have the request \&\fBreq\fR, which has the \s-1ASN.1\s0 type \fBit\fR. The \fBcontent_type\fR, if not \s-1NULL,\s0 will be included in the \s-1HTTP\s0 request. The function should be called after all other headers have already been added. .PP \&\fBOCSP_sendreq_bio()\fR performs an \s-1OCSP\s0 request using the responder \fBio\fR, the \s-1URL\s0 path \fBpath\fR, and the \s-1OCSP\s0 request \fBreq\fR with a response header maximum line length 4k. It waits indefinitely on a response. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOCSP_sendreq_new()\fR returns a valid \fB\s-1OCSP_REQ_CTX\s0\fR structure or \fB\s-1NULL\s0\fR if an error occurred. .PP \&\fBOCSP_sendreq_nbio()\fR returns \fB1\fR if the operation was completed successfully, \&\fB\-1\fR if the operation should be retried and \fB0\fR if an error occurred. .PP \&\fBOCSP_REQ_CTX_add1_header()\fR, \fBOCSP_REQ_CTX_set1_req()\fR, and \fBOCSP_REQ_CTX_i2d()\fR return \fB1\fR for success and \fB0\fR for failure. .PP \&\fBOCSP_sendreq_bio()\fR returns the \fB\s-1OCSP_RESPONSE\s0\fR structure sent by the responder or \fB\s-1NULL\s0\fR if an error occurred. .PP \&\fBOCSP_REQ_CTX_free()\fR and \fBOCSP_set_max_response_length()\fR do not return values. .SH "NOTES" .IX Header "NOTES" These functions only perform a minimal \s-1HTTP\s0 query to a responder. If an application wishes to support more advanced features it should use an alternative more complete \s-1HTTP\s0 library. .PP Currently only \s-1HTTP POST\s0 queries to responders are supported. .PP The arguments to \fBOCSP_sendreq_new()\fR correspond to the components of the \s-1URL.\s0 For example if the responder \s-1URL\s0 is \fBhttp://ocsp.com/ocspreq\fR the \s-1BIO\s0 \&\fBio\fR should be connected to host \fBocsp.com\fR on port 80 and \fBpath\fR should be set to \fB\*(L"/ocspreq\*(R"\fR .PP The headers added with \fBOCSP_REQ_CTX_add1_header()\fR are of the form "\fBname\fR: \fBvalue\fR\*(L" or just \*(R"\fBname\fR" if \fBvalue\fR is \fB\s-1NULL\s0\fR. So to add a Host header for \fBocsp.com\fR you would call: .PP .Vb 1 \& OCSP_REQ_CTX_add1_header(ctx, "Host", "ocsp.com"); .Ve .PP If \fBOCSP_sendreq_nbio()\fR indicates an operation should be retried the corresponding \s-1BIO\s0 can be examined to determine which operation (read or write) should be retried and appropriate action taken (for example a \fBselect()\fR call on the underlying socket). .PP \&\fBOCSP_sendreq_bio()\fR does not support retries and so cannot handle nonblocking I/O efficiently.

An \s-1ASYNC_WAIT_CTX\s0 object represents an asynchronous \&\*(L"session\*(R", i.e. a related set of crypto operations. For example in \s-1SSL\s0 terms this would have a one-to-one correspondence with an \s-1SSL\s0 connection. .PP Application code must create an \s-1ASYNC_WAIT_CTX\s0 using the \fBASYNC_WAIT_CTX_new()\fR function prior to calling \fBASYNC_start_job()\fR (see \fBASYNC_start_job\fR\|(3)). When the job is started it is associated with the \s-1ASYNC_WAIT_CTX\s0 for the duration of that job. An \s-1ASYNC_WAIT_CTX\s0 should only be used for one \s-1ASYNC_JOB\s0 at any one time, but can be reused after an \s-1ASYNC_JOB\s0 has finished for a subsequent \&\s-1ASYNC_JOB.\s0 When the session is complete (e.g. the \s-1SSL\s0 connection is closed), application code cleans up with \fBASYNC_WAIT_CTX_free()\fR. .PP ASYNC_WAIT_CTXs can have \*(L"wait\*(R" file descriptors associated with them. Calling \&\fBASYNC_WAIT_CTX_get_all_fds()\fR and passing in a pointer to an \s-1ASYNC_WAIT_CTX\s0 in the \fBctx\fR parameter will return the wait file descriptors associated with that job in \fB*fd\fR. The number of file descriptors returned will be stored in \&\fB*numfds\fR. It is the caller's responsibility to ensure that sufficient memory has been allocated in \fB*fd\fR to receive all the file descriptors. Calling \&\fBASYNC_WAIT_CTX_get_all_fds()\fR with a \s-1NULL\s0 \fBfd\fR value will return no file descriptors but will still populate \fB*numfds\fR. Therefore, application code is typically expected to call this function twice: once to get the number of fds, and then again when sufficient memory has been allocated. If only one asynchronous engine is being used then normally this call will only ever return one fd. If multiple asynchronous engines are being used then more could be returned. .PP The function \fBASYNC_WAIT_CTX_get_changed_fds()\fR can be used to detect if any fds have changed since the last call time \fBASYNC_start_job()\fR returned an \s-1ASYNC_PAUSE\s0 result (or since the \s-1ASYNC_WAIT_CTX\s0 was created if no \s-1ASYNC_PAUSE\s0 result has been received). The \fBnumaddfds\fR and \fBnumdelfds\fR parameters will be populated with the number of fds added or deleted respectively. \fB*addfd\fR and \fB*delfd\fR will be populated with the list of added and deleted fds respectively. Similarly to \fBASYNC_WAIT_CTX_get_all_fds()\fR either of these can be \s-1NULL,\s0 but if they are not \&\s-1NULL\s0 then the caller is responsible for ensuring sufficient memory is allocated. .PP Implementors of async aware code (e.g. engines) are encouraged to return a stable fd for the lifetime of the \s-1ASYNC_WAIT_CTX\s0 in order to reduce the \*(L"churn\*(R" of regularly changing fds \- although no guarantees of this are provided to applications. .PP Applications can wait for the file descriptor to be ready for \*(L"read\*(R" using a system function call such as select or poll (being ready for \*(L"read\*(R" indicates that the job should be resumed). If no file descriptor is made available then an application will have to periodically \*(L"poll\*(R" the job by attempting to restart it to see if it is ready to continue. .PP Async aware code (e.g. engines) can get the current \s-1ASYNC_WAIT_CTX\s0 from the job via \fBASYNC_get_wait_ctx\fR\|(3) and provide a file descriptor to use for waiting on by calling \fBASYNC_WAIT_CTX_set_wait_fd()\fR. Typically this would be done by an engine immediately prior to calling \fBASYNC_pause_job()\fR and not by end user code. An existing association with a file descriptor can be obtained using \&\fBASYNC_WAIT_CTX_get_fd()\fR and cleared using \fBASYNC_WAIT_CTX_clear_fd()\fR. Both of these functions requires a \fBkey\fR value which is unique to the async aware code. This could be any unique value but a good candidate might be the \&\fB\s-1ENGINE\s0 *\fR for the engine. The \fBcustom_data\fR parameter can be any value, and will be returned in a subsequent call to \fBASYNC_WAIT_CTX_get_fd()\fR. The \&\fBASYNC_WAIT_CTX_set_wait_fd()\fR function also expects a pointer to a \*(L"cleanup\*(R" routine. This can be \s-1NULL\s0 but if provided will automatically get called when the \s-1ASYNC_WAIT_CTX\s0 is freed, and gives the engine the opportunity to close the fd or any other resources. Note: The \*(L"cleanup\*(R" routine does not get called if the fd is cleared directly via a call to \fBASYNC_WAIT_CTX_clear_fd()\fR. .PP An example of typical usage might be an async capable engine. User code would initiate cryptographic operations. The engine would initiate those operations asynchronously and then call \fBASYNC_WAIT_CTX_set_wait_fd()\fR followed by \&\fBASYNC_pause_job()\fR to return control to the user code. The user code can then perform other tasks or wait for the job to be ready by calling \*(L"select\*(R" or other similar function on the wait file descriptor. The engine can signal to the user code that the job should be resumed by making the wait file descriptor \&\*(L"readable\*(R". Once resumed the engine should clear the wake signal on the wait file descriptor. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBASYNC_WAIT_CTX_new()\fR returns a pointer to the newly allocated \s-1ASYNC_WAIT_CTX\s0 or \&\s-1NULL\s0 on error. .PP ASYNC_WAIT_CTX_set_wait_fd, ASYNC_WAIT_CTX_get_fd, ASYNC_WAIT_CTX_get_all_fds, ASYNC_WAIT_CTX_get_changed_fds and ASYNC_WAIT_CTX_clear_fd all return 1 on success or 0 on error. .SH "NOTES" .IX Header "NOTES" On Windows platforms the openssl/async.h header is dependent on some of the types customarily made available by including windows.h.

In general, manual (re\-)seeding of the default OpenSSL random generator (\fBRAND_OpenSSL\fR\|(3)) is not necessary (but allowed), since it does (re\-)seed itself automatically using trusted system entropy sources. This holds unless the default \s-1RAND_METHOD\s0 has been replaced or OpenSSL was built with automatic reseeding disabled, see \s-1\fBRAND\s0\fR\|(7) for more details. .PP \&\fBRAND_status()\fR indicates whether or not the random generator has been sufficiently seeded. If not, functions such as \fBRAND_bytes\fR\|(3) will fail. .PP \&\fBRAND_poll()\fR uses the system's capabilities to seed the random generator using random input obtained from polling various trusted entropy sources. The default choice of the entropy source can be modified at build time, see \s-1\fBRAND\s0\fR\|(7) for more details. .PP \&\fBRAND_add()\fR mixes the \fBnum\fR bytes at \fBbuf\fR into the internal state of the random generator. This function will not normally be needed, as mentioned above. The \fBrandomness\fR argument is an estimate of how much randomness is contained in \&\fBbuf\fR, in bytes, and should be a number between zero and \fBnum\fR. Details about sources of randomness and how to estimate their randomness can be found in the literature; for example [\s-1NIST SP 800\-90B\s0]. The content of \fBbuf\fR cannot be recovered from subsequent random generator output. Applications that intend to save and restore random state in an external file should consider using \fBRAND_load_file\fR\|(3) instead. .PP \&\fBRAND_seed()\fR is equivalent to \fBRAND_add()\fR with \fBrandomness\fR set to \fBnum\fR. .PP \&\fBRAND_keep_random_devices_open()\fR is used to control file descriptor usage by the random seed sources. Some seed sources maintain open file descriptors by default, which allows such sources to operate in a \&\fBchroot\fR\|(2) jail without the associated device nodes being available. When the \fBkeep\fR argument is zero, this call disables the retention of file descriptors. Conversely, a nonzero argument enables the retention of file descriptors. This function is usually called during initialization and it takes effect immediately. .PP \&\fBRAND_event()\fR and \fBRAND_screen()\fR are equivalent to \fBRAND_poll()\fR and exist for compatibility reasons only. See \s-1HISTORY\s0 section below. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBRAND_status()\fR returns 1 if the random generator has been seeded with enough data, 0 otherwise. .PP \&\fBRAND_poll()\fR returns 1 if it generated seed data, 0 otherwise. .PP \&\fBRAND_event()\fR returns \fBRAND_status()\fR. .PP The other functions do not return values. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBRAND_bytes\fR\|(3), \&\fBRAND_egd\fR\|(3), \&\fBRAND_load_file\fR\|(3), \&\s-1\fBRAND\s0\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" \&\fBRAND_event()\fR and \fBRAND_screen()\fR were deprecated in OpenSSL 1.1.0 and should not be used. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

(This is implemented by calling \&\fBSSL_CTX_set0_chain()\fR with \fBsk\fR set to \fB\s-1NULL\s0\fR). .PP \&\fBSSL_CTX_build_cert_chain()\fR builds the certificate chain for \fBctx\fR normally this uses the chain store or the verify store if the chain store is not set. If the function is successful the built chain will replace any existing chain. The \fBflags\fR parameter can be set to \fB\s-1SSL_BUILD_CHAIN_FLAG_UNTRUSTED\s0\fR to use existing chain certificates as untrusted CAs, \fB\s-1SSL_BUILD_CHAIN_FLAG_NO_ROOT\s0\fR to omit the root \s-1CA\s0 from the built chain, \fB\s-1SSL_BUILD_CHAIN_FLAG_CHECK\s0\fR to use all existing chain certificates only to build the chain (effectively sanity checking and rearranging them if necessary), the flag \&\fB\s-1SSL_BUILD_CHAIN_FLAG_IGNORE_ERROR\s0\fR ignores any errors during verification: if flag \fB\s-1SSL_BUILD_CHAIN_FLAG_CLEAR_ERROR\s0\fR is also set verification errors are cleared from the error queue. .PP Each of these functions operates on the \fIcurrent\fR end entity (i.e. server or client) certificate. This is the last certificate loaded or selected on the corresponding \fBctx\fR structure. .PP \&\fBSSL_CTX_select_current_cert()\fR selects \fBx509\fR as the current end entity certificate, but only if \fBx509\fR has already been loaded into \fBctx\fR using a function such as \fBSSL_CTX_use_certificate()\fR. .PP \&\fBSSL_set0_chain()\fR, \fBSSL_set1_chain()\fR, \fBSSL_add0_chain_cert()\fR, \&\fBSSL_add1_chain_cert()\fR, \fBSSL_get0_chain_certs()\fR, \fBSSL_clear_chain_certs()\fR, \&\fBSSL_build_cert_chain()\fR, \fBSSL_select_current_cert()\fR and \fBSSL_set_current_cert()\fR are similar except they apply to \s-1SSL\s0 structure \fBssl\fR. .PP \&\fBSSL_CTX_set_current_cert()\fR changes the current certificate to a value based on the \fBop\fR argument. Currently \fBop\fR can be \fB\s-1SSL_CERT_SET_FIRST\s0\fR to use the first valid certificate or \fB\s-1SSL_CERT_SET_NEXT\s0\fR to set the next valid certificate after the current certificate. These two operations can be used to iterate over all certificates in an \fB\s-1SSL_CTX\s0\fR structure. .PP \&\fBSSL_set_current_cert()\fR also supports the option \fB\s-1SSL_CERT_SET_SERVER\s0\fR. If \fBssl\fR is a server and has sent a certificate to a connected client this option sets that certificate to the current certificate and returns 1. If the negotiated cipher suite is anonymous (and thus no certificate will be sent) 2 is returned and the current certificate is unchanged. If \fBssl\fR is not a server or a certificate has not been sent 0 is returned and the current certificate is unchanged. .PP All these functions are implemented as macros. Those containing a \fB1\fR increment the reference count of the supplied certificate or chain so it must be freed at some point after the operation. Those containing a \fB0\fR do not increment reference counts and the supplied certificate or chain \&\fB\s-1MUST NOT\s0\fR be freed after the operation. .SH "NOTES" .IX Header "NOTES" The chains associate with an \s-1SSL_CTX\s0 structure are copied to any \s-1SSL\s0 structures when \fBSSL_new()\fR is called. \s-1SSL\s0 structures will not be affected by any chains subsequently changed in the parent \s-1SSL_CTX.\s0 .PP One chain can be set for each key type supported by a server. So, for example, an \s-1RSA\s0 and a \s-1DSA\s0 certificate can (and often will) have different chains. .PP The functions \fBSSL_CTX_build_cert_chain()\fR and \fBSSL_build_cert_chain()\fR can be used to check application configuration and to ensure any necessary subordinate CAs are sent in the correct order. Misconfigured applications sending incorrect certificate chains often cause problems with peers. .PP For example an application can add any set of certificates using \&\fBSSL_CTX_use_certificate_chain_file()\fR then call \fBSSL_CTX_build_cert_chain()\fR with the option \fB\s-1SSL_BUILD_CHAIN_FLAG_CHECK\s0\fR to check and reorder them. .PP Applications can issue non fatal warnings when checking chains by setting the flag \fB\s-1SSL_BUILD_CHAIN_FLAG_IGNORE_ERRORS\s0\fR and checking the return value. .PP Calling \fBSSL_CTX_build_cert_chain()\fR or \fBSSL_build_cert_chain()\fR is more efficient than the automatic chain building as it is only performed once. Automatic chain building is performed on each new session. .PP If any certificates are added using these functions no certificates added using \fBSSL_CTX_add_extra_chain_cert()\fR will be used. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_set_current_cert()\fR with \fB\s-1SSL_CERT_SET_SERVER\s0\fR return 1 for success, 2 if no server certificate is used because the cipher suites is anonymous and 0 for failure. .PP \&\fBSSL_CTX_build_cert_chain()\fR and \fBSSL_build_cert_chain()\fR return 1 for success and 0 for failure.

This policy may be, for example, that at least one valid \s-1SCT\s0 is available. To determine this, an \s-1SCT\s0's timestamp and signature must be verified. This requires: .IP "\(bu" 2 the public key of the log that issued the \s-1SCT\s0 .IP "\(bu" 2 the certificate that the \s-1SCT\s0 was issued for .IP "\(bu" 2 the issuer certificate (if the \s-1SCT\s0 was issued for a pre-certificate) .IP "\(bu" 2 the current time .PP The above requirements are met using the setters described below. .PP \&\fBCT_POLICY_EVAL_CTX_new()\fR creates an empty policy evaluation context. This should then be populated using: .IP "\(bu" 2 \&\fBCT_POLICY_EVAL_CTX_set1_cert()\fR to provide the certificate the SCTs were issued for .Sp Increments the reference count of the certificate. .IP "\(bu" 2 \&\fBCT_POLICY_EVAL_CTX_set1_issuer()\fR to provide the issuer certificate .Sp Increments the reference count of the certificate. .IP "\(bu" 2 \&\fBCT_POLICY_EVAL_CTX_set_shared_CTLOG_STORE()\fR to provide a list of logs that are trusted as sources of SCTs .Sp Holds a pointer to the \s-1CTLOG_STORE,\s0 so the \s-1CTLOG_STORE\s0 must outlive the \&\s-1CT_POLICY_EVAL_CTX.\s0 .IP "\(bu" 2 \&\fBCT_POLICY_EVAL_CTX_set_time()\fR to set the time SCTs should be compared with to determine if they are valid .Sp The \s-1SCT\s0 timestamp will be compared to this time to check whether the \s-1SCT\s0 was issued in the future. \s-1RFC6962\s0 states that \*(L"\s-1TLS\s0 clients \s-1MUST\s0 reject SCTs whose timestamp is in the future\*(R". By default, this will be set to 5 minutes in the future (e.g. (\fBtime()\fR + 300) * 1000), to allow for clock drift. .Sp The time should be in milliseconds since the Unix epoch. .PP Each setter has a matching getter for accessing the current value. .PP When no longer required, the \fB\s-1CT_POLICY_EVAL_CTX\s0\fR should be passed to \&\fBCT_POLICY_EVAL_CTX_free()\fR to delete it. .SH "NOTES" .IX Header "NOTES" The issuer certificate only needs to be provided if at least one of the SCTs was issued for a pre-certificate. This will be the case for SCTs embedded in a certificate (i.e. those in an X.509 extension), but may not be the case for SCTs found in the \s-1TLS SCT\s0 extension or \s-1OCSP\s0 response. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBCT_POLICY_EVAL_CTX_new()\fR will return \s-1NULL\s0 if malloc fails. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBct\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" These functions were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016 The OpenSSL Project Authors.

i2d_TYPE_bio(BIO *bp, TYPE *a); .Ve .SH "DESCRIPTION" .IX Header "DESCRIPTION" In the description here, \fI\s-1TYPE\s0\fR is used a placeholder for any of the OpenSSL datatypes, such as \fIX509_CRL\fR. The function parameters \fIppin\fR and \fIppout\fR are generally either both named \fIpp\fR in the headers, or \fIin\fR and \fIout\fR. .PP These functions convert OpenSSL objects to and from their \s-1ASN.1/DER\s0 encoding. Unlike the C structures which can have pointers to sub-objects within, the \s-1DER\s0 is a serialized encoding, suitable for sending over the network, writing to a file, and so on. .PP \&\fBd2i_TYPE()\fR attempts to decode \fBlen\fR bytes at \fB*ppin\fR. If successful a pointer to the \fB\s-1TYPE\s0\fR structure is returned and \fB*ppin\fR is incremented to the byte following the parsed data. If \fBa\fR is not \fB\s-1NULL\s0\fR then a pointer to the returned structure is also written to \fB*a\fR. If an error occurred then \fB\s-1NULL\s0\fR is returned. .PP On a successful return, if \fB*a\fR is not \fB\s-1NULL\s0\fR then it is assumed that \fB*a\fR contains a valid \fB\s-1TYPE\s0\fR structure and an attempt is made to reuse it. This \&\*(L"reuse\*(R" capability is present for historical compatibility but its use is \&\fBstrongly discouraged\fR (see \s-1BUGS\s0 below, and the discussion in the \s-1RETURN VALUES\s0 section). .PP \&\fBd2i_TYPE_bio()\fR is similar to \fBd2i_TYPE()\fR except it attempts to parse data from \s-1BIO\s0 \fBbp\fR. .PP \&\fBd2i_TYPE_fp()\fR is similar to \fBd2i_TYPE()\fR except it attempts to parse data from \s-1FILE\s0 pointer \fBfp\fR. .PP \&\fBi2d_TYPE()\fR encodes the structure pointed to by \fBa\fR into \s-1DER\s0 format. If \fBppout\fR is not \fB\s-1NULL\s0\fR, it writes the \s-1DER\s0 encoded data to the buffer at \fB*ppout\fR, and increments it to point after the data just written. If the return value is negative an error occurred, otherwise it returns the length of the encoded data. .PP If \fB*ppout\fR is \fB\s-1NULL\s0\fR memory will be allocated for a buffer and the encoded data written to it. In this case \fB*ppout\fR is not incremented and it points to the start of the data just written. .PP \&\fBi2d_TYPE_bio()\fR is similar to \fBi2d_TYPE()\fR except it writes the encoding of the structure \fBa\fR to \s-1BIO\s0 \fBbp\fR and it returns 1 for success and 0 for failure. .PP \&\fBi2d_TYPE_fp()\fR is similar to \fBi2d_TYPE()\fR except it writes the encoding of the structure \fBa\fR to \s-1BIO\s0 \fBbp\fR and it returns 1 for success and 0 for failure. .PP These routines do not encrypt private keys and therefore offer no security; use \fBPEM_write_PrivateKey\fR\|(3) or similar for writing to files. .SH "NOTES" .IX Header "NOTES" The letters \fBi\fR and \fBd\fR in \fBi2d_TYPE\fR stand for \&\*(L"internal\*(R" (that is, an internal C structure) and \*(L"\s-1DER\*(R"\s0 respectively. So \fBi2d_TYPE\fR converts from internal to \s-1DER.\s0 .PP The functions can also understand \fB\s-1BER\s0\fR forms. .PP The actual \s-1TYPE\s0 structure passed to \fBi2d_TYPE()\fR must be a valid populated \fB\s-1TYPE\s0\fR structure \*(-- it \fBcannot\fR simply be fed with an empty structure such as that returned by \fBTYPE_new()\fR. .PP The encoded data is in binary form and may contain embedded zeros. Therefore, any \s-1FILE\s0 pointers or BIOs should be opened in binary mode. Functions such as \fBstrlen()\fR will \fBnot\fR return the correct length of the encoded structure. .PP The ways that \fB*ppin\fR and \fB*ppout\fR are incremented after the operation can trap the unwary. See the \fB\s-1WARNINGS\s0\fR section for some common errors. The reason for this-auto increment behaviour is to reflect a typical usage of \s-1ASN1\s0 functions: after one structure is encoded or decoded another will be processed after it. .PP The following points about the data types might be useful: .IP "\fB\s-1ASN1_OBJECT\s0\fR" 4 .IX Item "ASN1_OBJECT" Represents an \s-1ASN1 OBJECT IDENTIFIER.\s0 .IP "\fBDHparams\fR" 4 .IX Item "DHparams" Represents a PKCS#3 \s-1DH\s0 parameters structure. .IP "\fBDHxparams\fR" 4 .IX Item "DHxparams" Represents an \s-1ANSI X9.42 DH\s0 parameters structure. .IP "\fB\s-1DSA_PUBKEY\s0\fR" 4 .IX Item "DSA_PUBKEY" Represents a \s-1DSA\s0 public key using a \fBSubjectPublicKeyInfo\fR structure. .IP "\fBDSAPublicKey, DSAPrivateKey\fR" 4 .IX Item "DSAPublicKey, DSAPrivateKey" Use a non-standard OpenSSL format and should be avoided; use \fB\s-1DSA_PUBKEY\s0\fR, \&\fB\fBPEM_write_PrivateKey\fB\|(3)\fR, or similar instead. .IP "\fB\s-1ECDSA_SIG\s0\fR" 4 .IX Item "ECDSA_SIG" Represents an \s-1ECDSA\s0 signature. .IP "\fBRSAPublicKey\fR" 4 .IX Item "RSAPublicKey" Represents a PKCS#1 \s-1RSA\s0 public key structure. .IP "\fBX509_ALGOR\fR" 4 .IX Item "X509_ALGOR" Represents an \fBAlgorithmIdentifier\fR structure as used in \s-1IETF RFC 6960\s0 and elsewhere. .IP "\fBX509_Name\fR" 4 .IX Item "X509_Name" Represents a \fBName\fR type as used for subject and issuer names in \&\s-1IETF RFC 6960\s0 and elsewhere. .IP "\fBX509_REQ\fR" 4 .IX Item "X509_REQ" Represents a PKCS#10 certificate request. .IP "\fBX509_SIG\fR" 4 .IX Item "X509_SIG" Represents the \fBDigestInfo\fR structure defined in PKCS#1 and PKCS#7. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBd2i_TYPE()\fR, \fBd2i_TYPE_bio()\fR and \fBd2i_TYPE_fp()\fR return a valid \fB\s-1TYPE\s0\fR structure or \fB\s-1NULL\s0\fR if an error occurs.

Also \fBbuf\fR will no longer contain the pointer allocated by \fBOPENSSL_malloc()\fR and the subsequent call to \fBOPENSSL_free()\fR is likely to crash. .PP Another trap to avoid is misuse of the \fBa\fR argument to \fBd2i_TYPE()\fR: .PP .Vb 1 \& X509 *x; \& \& if (d2i_X509(&x, &p, len) == NULL) \& /* error */ .Ve .PP This will probably crash somewhere in \fBd2i_X509()\fR. The reason for this is that the variable \fBx\fR is uninitialized and an attempt will be made to interpret its (invalid) value as an \fBX509\fR structure, typically causing a segmentation violation. If \fBx\fR is set to \s-1NULL\s0 first then this will not happen. .SH "BUGS" .IX Header "BUGS" In some versions of OpenSSL the \*(L"reuse\*(R" behaviour of \fBd2i_TYPE()\fR when \&\fB*a\fR is valid is broken and some parts of the reused structure may persist if they are not present in the new one. Additionally, in versions of OpenSSL prior to 1.1.0, when the \*(L"reuse\*(R" behaviour is used and an error occurs the behaviour is inconsistent. Some functions behaved as described here, while some did not free \fB*a\fR on error and did not set \fB*a\fR to \s-1NULL.\s0 .PP As a result of the above issues the \*(L"reuse\*(R" behaviour is strongly discouraged. .PP \&\fBi2d_TYPE()\fR will not return an error in many versions of OpenSSL, if mandatory fields are not initialized due to a programming error then the encoded structure may contain invalid data or omit the fields entirely and will not be parsed by \fBd2i_TYPE()\fR. This may be fixed in future so code should not assume that \fBi2d_TYPE()\fR will always succeed. .PP Any function which encodes a structure (\fBi2d_TYPE()\fR, \&\fBi2d_TYPE()\fR or \fBi2d_TYPE()\fR) may return a stale encoding if the structure has been modified after deserialization or previous serialization. This is because some objects cache the encoding for efficiency reasons. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 1998\-2021 The OpenSSL Project Authors.

It contains a scheme and the functions needed to implement \&\fBOSSL_STORE_open()\fR, \fBOSSL_STORE_load()\fR, \fBOSSL_STORE_eof()\fR, \fBOSSL_STORE_error()\fR and \&\fBOSSL_STORE_close()\fR for this scheme. .PP \&\fB\s-1OSSL_STORE_LOADER_CTX\s0\fR is a type template, to be defined by each loader using \fBstruct ossl_store_loader_ctx_st { ... }\fR. .PP \&\fBOSSL_STORE_open_fn\fR, \fBOSSL_STORE_ctrl_fn\fR, \fBOSSL_STORE_expect_fn\fR, \&\fBOSSL_STORE_find_fn\fR, \fBOSSL_STORE_load_fn\fR, \fBOSSL_STORE_eof_fn\fR, and \fBOSSL_STORE_close_fn\fR are the function pointer types used within a \s-1STORE\s0 loader. The functions pointed at define the functionality of the given loader. .IP "\fBOSSL_STORE_open_fn\fR" 4 .IX Item "OSSL_STORE_open_fn" This function takes a \s-1URI\s0 and is expected to interpret it in the best manner possible according to the scheme the loader implements, it also takes a \fB\s-1UI_METHOD\s0\fR and associated data, to be used any time something needs to be prompted for. Furthermore, this function is expected to initialize what needs to be initialized, to create a private data store (\fB\s-1OSSL_STORE_LOADER_CTX\s0\fR, see above), and to return it. If something goes wrong, this function is expected to return \s-1NULL.\s0 .IP "\fBOSSL_STORE_ctrl_fn\fR" 4 .IX Item "OSSL_STORE_ctrl_fn" This function takes a \fB\s-1OSSL_STORE_LOADER_CTX\s0\fR pointer, a command number \&\fBcmd\fR and a \fBva_list\fR \fBargs\fR and is used to manipulate loader specific parameters. .Sp Loader specific command numbers must begin at \fB\s-1OSSL_STORE_C_CUSTOM_START\s0\fR. Any number below that is reserved for future globally known command numbers. .Sp This function is expected to return 1 on success, 0 on error. .IP "\fBOSSL_STORE_expect_fn\fR" 4 .IX Item "OSSL_STORE_expect_fn" This function takes a \fB\s-1OSSL_STORE_LOADER_CTX\s0\fR pointer and a \fB\s-1OSSL_STORE_INFO\s0\fR identity \fBexpected\fR, and is used to tell the loader what object type is expected. \&\fBexpected\fR may be zero to signify that no specific object type is expected. .Sp This function is expected to return 1 on success, 0 on error. .IP "\fBOSSL_STORE_find_fn\fR" 4 .IX Item "OSSL_STORE_find_fn" This function takes a \fB\s-1OSSL_STORE_LOADER_CTX\s0\fR pointer and a \&\fB\s-1OSSL_STORE_SEARCH\s0\fR search criterion, and is used to tell the loader what to search for. .Sp When called with the loader context being \fB\s-1NULL\s0\fR, this function is expected to return 1 if the loader supports the criterion, otherwise 0. .Sp When called with the loader context being something other than \fB\s-1NULL\s0\fR, this function is expected to return 1 on success, 0 on error. .IP "\fBOSSL_STORE_load_fn\fR" 4 .IX Item "OSSL_STORE_load_fn" This function takes a \fB\s-1OSSL_STORE_LOADER_CTX\s0\fR pointer and a \fB\s-1UI_METHOD\s0\fR with associated data. It's expected to load the next available data, mold it into a data structure that can be wrapped in a \fB\s-1OSSL_STORE_INFO\s0\fR using one of the \&\s-1\fBOSSL_STORE_INFO\s0\fR\|(3) functions. If no more data is available or an error occurs, this function is expected to return \s-1NULL.\s0 The \fBOSSL_STORE_eof_fn\fR and \fBOSSL_STORE_error_fn\fR functions must indicate if it was in fact the end of data or if an error occurred. .Sp Note that this function retrieves \fIone\fR data item only. .IP "\fBOSSL_STORE_eof_fn\fR" 4 .IX Item "OSSL_STORE_eof_fn" This function takes a \fB\s-1OSSL_STORE_LOADER_CTX\s0\fR pointer and is expected to return 1 to indicate that the end of available data has been reached. It is otherwise expected to return 0. .IP "\fBOSSL_STORE_error_fn\fR" 4 .IX Item "OSSL_STORE_error_fn" This function takes a \fB\s-1OSSL_STORE_LOADER_CTX\s0\fR pointer and is expected to return 1 to indicate that an error occurred in a previous call to the \&\fBOSSL_STORE_load_fn\fR function. It is otherwise expected to return 0. .IP "\fBOSSL_STORE_close_fn\fR" 4 .IX Item "OSSL_STORE_close_fn" This function takes a \fB\s-1OSSL_STORE_LOADER_CTX\s0\fR pointer and is expected to close or shut down what needs to be closed, and finally free the contents of the \fB\s-1OSSL_STORE_LOADER_CTX\s0\fR pointer. It returns 1 on success and 0 on error. .SS "Functions" .IX Subsection "Functions" \&\fBOSSL_STORE_LOADER_new()\fR creates a new \fB\s-1OSSL_STORE_LOADER\s0\fR. It takes an \fB\s-1ENGINE\s0\fR \fBe\fR and a string \fBscheme\fR. \&\fBscheme\fR must \fIalways\fR be set. Both \fBe\fR and \fBscheme\fR are used as is and must therefore be alive as long as the created loader is. .PP \&\fBOSSL_STORE_LOADER_get0_engine()\fR returns the engine of the \fBstore_loader\fR. \&\fBOSSL_STORE_LOADER_get0_scheme()\fR returns the scheme of the \fBstore_loader\fR. .PP \&\fBOSSL_STORE_LOADER_set_open()\fR sets the opener function for the \&\fBstore_loader\fR. .PP \&\fBOSSL_STORE_LOADER_set_ctrl()\fR sets the control function for the \&\fBstore_loader\fR. .PP \&\fBOSSL_STORE_LOADER_set_expect()\fR sets the expect function for the \&\fBstore_loader\fR. .PP \&\fBOSSL_STORE_LOADER_set_load()\fR sets the loader function for the \&\fBstore_loader\fR. .PP \&\fBOSSL_STORE_LOADER_set_eof()\fR sets the end of file checker function for the \&\fBstore_loader\fR. .PP \&\fBOSSL_STORE_LOADER_set_close()\fR sets the closing function for the \&\fBstore_loader\fR. .PP \&\fBOSSL_STORE_LOADER_free()\fR frees the given \fBstore_loader\fR. .PP \&\fBOSSL_STORE_register_loader()\fR register the given \fBstore_loader\fR and thereby makes it available for use with \fBOSSL_STORE_open()\fR, \fBOSSL_STORE_load()\fR, \&\fBOSSL_STORE_eof()\fR and \fBOSSL_STORE_close()\fR. .PP \&\fBOSSL_STORE_unregister_loader()\fR unregister the store loader for the given \&\fBscheme\fR. .SH "NOTES" .IX Header "NOTES" The \fBfile:\fR scheme has built in support. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The functions with the types \fBOSSL_STORE_open_fn\fR, \fBOSSL_STORE_ctrl_fn\fR, \&\fBOSSL_STORE_expect_fn\fR, \&\fBOSSL_STORE_load_fn\fR, \fBOSSL_STORE_eof_fn\fR and \fBOSSL_STORE_close_fn\fR have the same return values as \fBOSSL_STORE_open()\fR, \fBOSSL_STORE_ctrl()\fR, \fBOSSL_STORE_expect()\fR, \&\fBOSSL_STORE_load()\fR, \fBOSSL_STORE_eof()\fR and \fBOSSL_STORE_close()\fR, respectively. .PP \&\fBOSSL_STORE_LOADER_new()\fR returns a pointer to a \fB\s-1OSSL_STORE_LOADER\s0\fR on success, or \fB\s-1NULL\s0\fR on failure. .PP \&\fBOSSL_STORE_LOADER_set_open()\fR, \fBOSSL_STORE_LOADER_set_ctrl()\fR, \&\fBOSSL_STORE_LOADER_set_load()\fR, \fBOSSL_STORE_LOADER_set_eof()\fR and \&\fBOSSL_STORE_LOADER_set_close()\fR return 1 on success, or 0 on failure. .PP \&\fBOSSL_STORE_register_loader()\fR returns 1 on success, or 0 on failure. .PP \&\fBOSSL_STORE_unregister_loader()\fR returns the unregistered loader on success, or \fB\s-1NULL\s0\fR on failure. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBossl_store\fR\|(7), \fBOSSL_STORE_open\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\s-1\fBOSSL_STORE_LOADER\s0()\fR, \s-1\fBOSSL_STORE_LOADER_CTX\s0()\fR, \fBOSSL_STORE_LOADER_new()\fR, \&\fBOSSL_STORE_LOADER_set0_scheme()\fR, \fBOSSL_STORE_LOADER_set_open()\fR, \&\fBOSSL_STORE_LOADER_set_ctrl()\fR, \fBOSSL_STORE_LOADER_set_load()\fR, \&\fBOSSL_STORE_LOADER_set_eof()\fR, \fBOSSL_STORE_LOADER_set_close()\fR, \&\fBOSSL_STORE_LOADER_free()\fR, \fBOSSL_STORE_register_loader()\fR, \&\fBOSSL_STORE_unregister_loader()\fR, \fBOSSL_STORE_open_fn()\fR, \fBOSSL_STORE_ctrl_fn()\fR, \&\fBOSSL_STORE_load_fn()\fR, \fBOSSL_STORE_eof_fn()\fR and \fBOSSL_STORE_close_fn()\fR were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2019 The OpenSSL Project Authors.

The key type used must match \fBkeytype\fR if it is not \-1. The parameter \&\fBoptype\fR is a mask indicating which operations the control can be applied to. The control command is indicated in \fBcmd\fR and any additional arguments in \&\fBp1\fR and \fBp2\fR. .PP For \fBcmd\fR = \fB\s-1EVP_PKEY_CTRL_SET_MAC_KEY\s0\fR, \fBp1\fR is the length of the \s-1MAC\s0 key, and \fBp2\fR is \s-1MAC\s0 key. This is used by Poly1305, SipHash, \s-1HMAC\s0 and \s-1CMAC.\s0 .PP Applications will not normally call \fBEVP_PKEY_CTX_ctrl()\fR directly but will instead call one of the algorithm specific macros below. .PP The function \fBEVP_PKEY_CTX_ctrl_uint64()\fR is a wrapper that directly passes a uint64 value as \fBp2\fR to \fBEVP_PKEY_CTX_ctrl()\fR. .PP The function \fBEVP_PKEY_CTX_ctrl_str()\fR allows an application to send an algorithm specific control operation to a context \fBctx\fR in string form. This is intended to be used for options specified on the command line or in text files. The commands supported are documented in the openssl utility command line pages for the option \fB\-pkeyopt\fR which is supported by the \&\fBpkeyutl\fR, \fBgenpkey\fR and \fBreq\fR commands. .PP The function \fBEVP_PKEY_CTX_md()\fR sends a message digest control operation to the context \fBctx\fR. The message digest is specified by its name \fBmd\fR. .PP All the remaining \*(L"functions\*(R" are implemented as macros. .PP The \fBEVP_PKEY_CTX_set_signature_md()\fR macro sets the message digest type used in a signature. It can be used in the \s-1RSA, DSA\s0 and \s-1ECDSA\s0 algorithms. .PP The \fBEVP_PKEY_CTX_get_signature_md()\fR macro gets the message digest type used in a signature. It can be used in the \s-1RSA, DSA\s0 and \s-1ECDSA\s0 algorithms. .PP Key generation typically involves setting up parameters to be used and generating the private and public key data. Some algorithm implementations allow private key data to be set explicitly using the \fBEVP_PKEY_CTX_set_mac_key()\fR macro. In this case key generation is simply the process of setting up the parameters for the key and then setting the raw key data to the value explicitly provided by that macro. Normally applications would call \&\fBEVP_PKEY_new_raw_private_key\fR\|(3) or similar functions instead of this macro. .PP The \fBEVP_PKEY_CTX_set_mac_key()\fR macro can be used with any of the algorithms supported by the \fBEVP_PKEY_new_raw_private_key\fR\|(3) function. .SS "\s-1RSA\s0 parameters" .IX Subsection "RSA parameters" The \fBEVP_PKEY_CTX_set_rsa_padding()\fR macro sets the \s-1RSA\s0 padding mode for \fBctx\fR. The \fBpad\fR parameter can take the value \fB\s-1RSA_PKCS1_PADDING\s0\fR for PKCS#1 padding, \fB\s-1RSA_SSLV23_PADDING\s0\fR for SSLv23 padding, \fB\s-1RSA_NO_PADDING\s0\fR for no padding, \fB\s-1RSA_PKCS1_OAEP_PADDING\s0\fR for \s-1OAEP\s0 padding (encrypt and decrypt only), \fB\s-1RSA_X931_PADDING\s0\fR for X9.31 padding (signature operations only) and \fB\s-1RSA_PKCS1_PSS_PADDING\s0\fR (sign and verify only). .PP Two \s-1RSA\s0 padding modes behave differently if \fBEVP_PKEY_CTX_set_signature_md()\fR is used. If this macro is called for PKCS#1 padding the plaintext buffer is an actual digest value and is encapsulated in a DigestInfo structure according to PKCS#1 when signing and this structure is expected (and stripped off) when verifying. If this control is not used with \s-1RSA\s0 and PKCS#1 padding then the supplied data is used directly and not encapsulated. In the case of X9.31 padding for \s-1RSA\s0 the algorithm identifier byte is added or checked and removed if this control is called. If it is not called then the first byte of the plaintext buffer is expected to be the algorithm identifier byte. .PP The \fBEVP_PKEY_CTX_get_rsa_padding()\fR macro gets the \s-1RSA\s0 padding mode for \fBctx\fR. .PP The \fBEVP_PKEY_CTX_set_rsa_pss_saltlen()\fR macro sets the \s-1RSA PSS\s0 salt length to \&\fBlen\fR. As its name implies it is only supported for \s-1PSS\s0 padding. Three special values are supported: \fB\s-1RSA_PSS_SALTLEN_DIGEST\s0\fR sets the salt length to the digest length, \fB\s-1RSA_PSS_SALTLEN_MAX\s0\fR sets the salt length to the maximum permissible value. When verifying \fB\s-1RSA_PSS_SALTLEN_AUTO\s0\fR causes the salt length to be automatically determined based on the \fB\s-1PSS\s0\fR block structure. If this macro is not called maximum salt length is used when signing and auto detection when verifying is used by default. .PP The \fBEVP_PKEY_CTX_get_rsa_pss_saltlen()\fR macro gets the \s-1RSA PSS\s0 salt length for \fBctx\fR. The padding mode must have been set to \fB\s-1RSA_PKCS1_PSS_PADDING\s0\fR. .PP The \fBEVP_PKEY_CTX_set_rsa_keygen_bits()\fR macro sets the \s-1RSA\s0 key length for \&\s-1RSA\s0 key generation to \fBbits\fR. If not specified 1024 bits is used. .PP The \fBEVP_PKEY_CTX_set_rsa_keygen_pubexp()\fR macro sets the public exponent value for \s-1RSA\s0 key generation to \fBpubexp\fR. Currently it should be an odd integer. The \&\fBpubexp\fR pointer is used internally by this function so it should not be modified or freed after the call. If not specified 65537 is used. .PP The \fBEVP_PKEY_CTX_set_rsa_keygen_primes()\fR macro sets the number of primes for \&\s-1RSA\s0 key generation to \fBprimes\fR. If not specified 2 is used. .PP The \fBEVP_PKEY_CTX_set_rsa_mgf1_md()\fR macro sets the \s-1MGF1\s0 digest for \s-1RSA\s0 padding schemes to \fBmd\fR. If not explicitly set the signing digest is used. The padding mode must have been set to \fB\s-1RSA_PKCS1_OAEP_PADDING\s0\fR or \fB\s-1RSA_PKCS1_PSS_PADDING\s0\fR. .PP The \fBEVP_PKEY_CTX_get_rsa_mgf1_md()\fR macro gets the \s-1MGF1\s0 digest for \fBctx\fR. If not explicitly set the signing digest is used. The padding mode must have been set to \fB\s-1RSA_PKCS1_OAEP_PADDING\s0\fR or \fB\s-1RSA_PKCS1_PSS_PADDING\s0\fR. .PP The \fBEVP_PKEY_CTX_set_rsa_oaep_md()\fR macro sets the message digest type used in \s-1RSA OAEP\s0 to \fBmd\fR. The padding mode must have been set to \&\fB\s-1RSA_PKCS1_OAEP_PADDING\s0\fR. .PP The \fBEVP_PKEY_CTX_get_rsa_oaep_md()\fR macro gets the message digest type used in \s-1RSA OAEP\s0 to \fBmd\fR. The padding mode must have been set to \&\fB\s-1RSA_PKCS1_OAEP_PADDING\s0\fR. .PP The \fBEVP_PKEY_CTX_set0_rsa_oaep_label()\fR macro sets the \s-1RSA OAEP\s0 label to \&\fBlabel\fR and its length to \fBlen\fR. If \fBlabel\fR is \s-1NULL\s0 or \fBlen\fR is 0, the label is cleared. The library takes ownership of the label so the caller should not free the original memory pointed to by \fBlabel\fR. The padding mode must have been set to \fB\s-1RSA_PKCS1_OAEP_PADDING\s0\fR. .PP The \fBEVP_PKEY_CTX_get0_rsa_oaep_label()\fR macro gets the \s-1RSA OAEP\s0 label to \&\fBlabel\fR. The return value is the label length. The padding mode must have been set to \fB\s-1RSA_PKCS1_OAEP_PADDING\s0\fR. The resulting pointer is owned by the library and should not be freed by the caller. .SS "\s-1DSA\s0 parameters" .IX Subsection "DSA parameters" The \fBEVP_PKEY_CTX_set_dsa_paramgen_bits()\fR macro sets the number of bits used for \s-1DSA\s0 parameter generation to \fBnbits\fR. If not specified, 1024 is used. .PP The \fBEVP_PKEY_CTX_set_dsa_paramgen_q_bits()\fR macro sets the number of bits in the subprime parameter \fBq\fR for \s-1DSA\s0 parameter generation to \fBqbits\fR. If not specified, 160 is used. If a digest function is specified below, this parameter is ignored and instead, the number of bits in \fBq\fR matches the size of the digest. .PP The \fBEVP_PKEY_CTX_set_dsa_paramgen_md()\fR macro sets the digest function used for \&\s-1DSA\s0 parameter generation to \fBmd\fR. If not specified, one of \s-1SHA\-1, SHA\-224,\s0 or \&\s-1SHA\-256\s0 is selected to match the bit length of \fBq\fR above. .SS "\s-1DH\s0 parameters" .IX Subsection "DH parameters" The \fBEVP_PKEY_CTX_set_dh_paramgen_prime_len()\fR macro sets the length of the \s-1DH\s0 prime parameter \fBp\fR for \s-1DH\s0 parameter generation. If this macro is not called then 1024 is used. Only accepts lengths greater than or equal to 256. .PP The \fBEVP_PKEY_CTX_set_dh_paramgen_subprime_len()\fR macro sets the length of the \s-1DH\s0 optional subprime parameter \fBq\fR for \s-1DH\s0 parameter generation. The default is 256 if the prime is at least 2048 bits long or 160 otherwise. The \s-1DH\s0 paramgen type must have been set to x9.42. .PP The \fBEVP_PKEY_CTX_set_dh_paramgen_generator()\fR macro sets \s-1DH\s0 generator to \fBgen\fR for \s-1DH\s0 parameter generation. If not specified 2 is used. .PP The \fBEVP_PKEY_CTX_set_dh_paramgen_type()\fR macro sets the key type for \s-1DH\s0 parameter generation. Use 0 for PKCS#3 \s-1DH\s0 and 1 for X9.42 \s-1DH.\s0 The default is 0. .PP The \fBEVP_PKEY_CTX_set_dh_pad()\fR macro sets the \s-1DH\s0 padding mode. If \fBpad\fR is 1 the shared secret is padded with zeros up to the size of the \s-1DH\s0 prime \fBp\fR. If \fBpad\fR is zero (the default) then no padding is performed. .PP \&\fBEVP_PKEY_CTX_set_dh_nid()\fR sets the \s-1DH\s0 parameters to values corresponding to \&\fBnid\fR as defined in \s-1RFC7919.\s0 The \fBnid\fR parameter must be \fBNID_ffdhe2048\fR, \&\fBNID_ffdhe3072\fR, \fBNID_ffdhe4096\fR, \fBNID_ffdhe6144\fR, \fBNID_ffdhe8192\fR or \fBNID_undef\fR to clear the stored value. This macro can be called during parameter or key generation. The nid parameter and the rfc5114 parameter are mutually exclusive. .PP The \fBEVP_PKEY_CTX_set_dh_rfc5114()\fR and \fBEVP_PKEY_CTX_set_dhx_rfc5114()\fR macros are synonymous. They set the \s-1DH\s0 parameters to the values defined in \s-1RFC5114.\s0 The \&\fBrfc5114\fR parameter must be 1, 2 or 3 corresponding to \s-1RFC5114\s0 sections 2.1, 2.2 and 2.3. or 0 to clear the stored value. This macro can be called during parameter generation. The \fBctx\fR must have a key type of \&\fB\s-1EVP_PKEY_DHX\s0\fR. The rfc5114 parameter and the nid parameter are mutually exclusive. .SS "\s-1DH\s0 key derivation function parameters" .IX Subsection "DH key derivation function parameters" Note that all of the following functions require that the \fBctx\fR parameter has a private key type of \fB\s-1EVP_PKEY_DHX\s0\fR. When using key derivation, the output of \&\fBEVP_PKEY_derive()\fR is the output of the \s-1KDF\s0 instead of the \s-1DH\s0 shared secret. The \s-1KDF\s0 output is typically used as a Key Encryption Key (\s-1KEK\s0) that in turn encrypts a Content Encryption Key (\s-1CEK\s0). .PP The \fBEVP_PKEY_CTX_set_dh_kdf_type()\fR macro sets the key derivation function type to \fBkdf\fR for \s-1DH\s0 key derivation. Possible values are \fB\s-1EVP_PKEY_DH_KDF_NONE\s0\fR and \fB\s-1EVP_PKEY_DH_KDF_X9_42\s0\fR which uses the key derivation specified in \s-1RFC2631\s0 (based on the keying algorithm described in X9.42). When using key derivation, the \fBkdf_oid\fR, \fBkdf_md\fR and \fBkdf_outlen\fR parameters must also be specified. .PP The \fBEVP_PKEY_CTX_get_dh_kdf_type()\fR macro gets the key derivation function type for \fBctx\fR used for \s-1DH\s0 key derivation. Possible values are \fB\s-1EVP_PKEY_DH_KDF_NONE\s0\fR and \fB\s-1EVP_PKEY_DH_KDF_X9_42\s0\fR. .PP The \fBEVP_PKEY_CTX_set0_dh_kdf_oid()\fR macro sets the key derivation function object identifier to \fBoid\fR for \s-1DH\s0 key derivation. This \s-1OID\s0 should identify the algorithm to be used with the Content Encryption Key. The library takes ownership of the object identifier so the caller should not free the original memory pointed to by \fBoid\fR. .PP The \fBEVP_PKEY_CTX_get0_dh_kdf_oid()\fR macro gets the key derivation function oid for \fBctx\fR used for \s-1DH\s0 key derivation. The resulting pointer is owned by the library and should not be freed by the caller. .PP The \fBEVP_PKEY_CTX_set_dh_kdf_md()\fR macro sets the key derivation function message digest to \fBmd\fR for \s-1DH\s0 key derivation. Note that \s-1RFC2631\s0 specifies that this digest should be \s-1SHA1\s0 but OpenSSL tolerates other digests. .PP The \fBEVP_PKEY_CTX_get_dh_kdf_md()\fR macro gets the key derivation function message digest for \fBctx\fR used for \s-1DH\s0 key derivation. .PP The \fBEVP_PKEY_CTX_set_dh_kdf_outlen()\fR macro sets the key derivation function output length to \fBlen\fR for \s-1DH\s0 key derivation. .PP The \fBEVP_PKEY_CTX_get_dh_kdf_outlen()\fR macro gets the key derivation function output length for \fBctx\fR used for \s-1DH\s0 key derivation. .PP The \fBEVP_PKEY_CTX_set0_dh_kdf_ukm()\fR macro sets the user key material to \&\fBukm\fR and its length to \fBlen\fR for \s-1DH\s0 key derivation. This parameter is optional and corresponds to the partyAInfo field in \s-1RFC2631\s0 terms. The specification requires that it is 512 bits long but this is not enforced by OpenSSL. The library takes ownership of the user key material so the caller should not free the original memory pointed to by \fBukm\fR. .PP The \fBEVP_PKEY_CTX_get0_dh_kdf_ukm()\fR macro gets the user key material for \fBctx\fR. The return value is the user key material length. The resulting pointer is owned by the library and should not be freed by the caller. .SS "\s-1EC\s0 parameters" .IX Subsection "EC parameters" The \fBEVP_PKEY_CTX_set_ec_paramgen_curve_nid()\fR sets the \s-1EC\s0 curve for \s-1EC\s0 parameter generation to \fBnid\fR. For \s-1EC\s0 parameter generation this macro must be called or an error occurs because there is no default curve. This function can also be called to set the curve explicitly when generating an \s-1EC\s0 key. .PP The \fBEVP_PKEY_CTX_set_ec_param_enc()\fR macro sets the \s-1EC\s0 parameter encoding to \&\fBparam_enc\fR when generating \s-1EC\s0 parameters or an \s-1EC\s0 key. The encoding can be \&\fB\s-1OPENSSL_EC_EXPLICIT_CURVE\s0\fR for explicit parameters (the default in versions of OpenSSL before 1.1.0) or \fB\s-1OPENSSL_EC_NAMED_CURVE\s0\fR to use named curve form. For maximum compatibility the named curve form should be used. Note: the \&\fB\s-1OPENSSL_EC_NAMED_CURVE\s0\fR value was added in OpenSSL 1.1.0; previous versions should use 0 instead. .SS "\s-1ECDH\s0 parameters" .IX Subsection "ECDH parameters" The \fBEVP_PKEY_CTX_set_ecdh_cofactor_mode()\fR macro sets the cofactor mode to \&\fBcofactor_mode\fR for \s-1ECDH\s0 key derivation. Possible values are 1 to enable cofactor key derivation, 0 to disable it and \-1 to clear the stored cofactor mode and fallback to the private key cofactor mode. .PP The \fBEVP_PKEY_CTX_get_ecdh_cofactor_mode()\fR macro returns the cofactor mode for \&\fBctx\fR used for \s-1ECDH\s0 key derivation. Possible values are 1 when cofactor key derivation is enabled and 0 otherwise. .SS "\s-1ECDH\s0 key derivation function parameters" .IX Subsection "ECDH key derivation function parameters" The \fBEVP_PKEY_CTX_set_ecdh_kdf_type()\fR macro sets the key derivation function type to \fBkdf\fR for \s-1ECDH\s0 key derivation. Possible values are \fB\s-1EVP_PKEY_ECDH_KDF_NONE\s0\fR and \fB\s-1EVP_PKEY_ECDH_KDF_X9_63\s0\fR which uses the key derivation specified in X9.63. When using key derivation, the \fBkdf_md\fR and \fBkdf_outlen\fR parameters must also be specified. .PP The \fBEVP_PKEY_CTX_get_ecdh_kdf_type()\fR macro returns the key derivation function type for \fBctx\fR used for \s-1ECDH\s0 key derivation. Possible values are \&\fB\s-1EVP_PKEY_ECDH_KDF_NONE\s0\fR and \fB\s-1EVP_PKEY_ECDH_KDF_X9_63\s0\fR. .PP The \fBEVP_PKEY_CTX_set_ecdh_kdf_md()\fR macro sets the key derivation function message digest to \fBmd\fR for \s-1ECDH\s0 key derivation. Note that X9.63 specifies that this digest should be \s-1SHA1\s0 but OpenSSL tolerates other digests. .PP The \fBEVP_PKEY_CTX_get_ecdh_kdf_md()\fR macro gets the key derivation function message digest for \fBctx\fR used for \s-1ECDH\s0 key derivation. .PP The \fBEVP_PKEY_CTX_set_ecdh_kdf_outlen()\fR macro sets the key derivation function output length to \fBlen\fR for \s-1ECDH\s0 key derivation. .PP The \fBEVP_PKEY_CTX_get_ecdh_kdf_outlen()\fR macro gets the key derivation function output length for \fBctx\fR used for \s-1ECDH\s0 key derivation. .PP The \fBEVP_PKEY_CTX_set0_ecdh_kdf_ukm()\fR macro sets the user key material to \fBukm\fR for \s-1ECDH\s0 key derivation. This parameter is optional and corresponds to the shared info in X9.63 terms. The library takes ownership of the user key material so the caller should not free the original memory pointed to by \fBukm\fR. .PP The \fBEVP_PKEY_CTX_get0_ecdh_kdf_ukm()\fR macro gets the user key material for \fBctx\fR. The return value is the user key material length. The resulting pointer is owned by the library and should not be freed by the caller. .SS "Other parameters" .IX Subsection "Other parameters" The \fBEVP_PKEY_CTX_set1_id()\fR, \fBEVP_PKEY_CTX_get1_id()\fR and \fBEVP_PKEY_CTX_get1_id_len()\fR macros are used to manipulate the special identifier field for specific signature algorithms such as \s-1SM2.\s0 The \fBEVP_PKEY_CTX_set1_id()\fR sets an \s-1ID\s0 pointed by \fBid\fR with the length \fBid_len\fR to the library. The library takes a copy of the id so that the caller can safely free the original memory pointed to by \fBid\fR. The \&\fBEVP_PKEY_CTX_get1_id_len()\fR macro returns the length of the \s-1ID\s0 set via a previous call to \fBEVP_PKEY_CTX_set1_id()\fR. The length is usually used to allocate adequate memory for further calls to \fBEVP_PKEY_CTX_get1_id()\fR. The \fBEVP_PKEY_CTX_get1_id()\fR macro returns the previously set \s-1ID\s0 value to caller in \fBid\fR. The caller should allocate adequate memory space for the \fBid\fR before calling \fBEVP_PKEY_CTX_get1_id()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_PKEY_CTX_ctrl()\fR and its macros return a positive value for success and 0 or a negative value for failure.

The \&\s-1OID\s0 associated with the algorithm is set to \fBaobj\fR. The type of the algorithm parameters is set to \fBtype\fR using the structure \fBpval\fR.

The reference count is set to \&\fB1\fR. .PP \&\fBEVP_PKEY_up_ref()\fR increments the reference count of \fBkey\fR. .PP \&\fBEVP_PKEY_free()\fR decrements the reference count of \fBkey\fR and, if the reference count is zero, frees it up. If \fBkey\fR is \s-1NULL,\s0 nothing is done. .PP \&\fBEVP_PKEY_new_raw_private_key()\fR allocates a new \fB\s-1EVP_PKEY\s0\fR. If \fBe\fR is non-NULL then the new \fB\s-1EVP_PKEY\s0\fR structure is associated with the engine \fBe\fR. The \&\fBtype\fR argument indicates what kind of key this is. The value should be a \s-1NID\s0 for a public key algorithm that supports raw private keys, i.e. one of \&\fB\s-1EVP_PKEY_HMAC\s0\fR, \fB\s-1EVP_PKEY_POLY1305\s0\fR, \fB\s-1EVP_PKEY_SIPHASH\s0\fR, \fB\s-1EVP_PKEY_X25519\s0\fR, \&\fB\s-1EVP_PKEY_ED25519\s0\fR, \fB\s-1EVP_PKEY_X448\s0\fR or \fB\s-1EVP_PKEY_ED448\s0\fR. \fBkey\fR points to the raw private key data for this \fB\s-1EVP_PKEY\s0\fR which should be of length \fBkeylen\fR. The length should be appropriate for the type of the key. The public key data will be automatically derived from the given private key data (if appropriate for the algorithm type). .PP \&\fBEVP_PKEY_new_raw_public_key()\fR works in the same way as \&\fBEVP_PKEY_new_raw_private_key()\fR except that \fBkey\fR points to the raw public key data.

In addition to the raw private key data, it also takes a cipher algorithm to be used during creation of a \s-1CMAC\s0 in the \fBcipher\fR argument. The cipher should be a standard encryption only cipher. For example \s-1AEAD\s0 and \s-1XTS\s0 ciphers should not be used. .PP \&\fBEVP_PKEY_new_mac_key()\fR works in the same way as \fBEVP_PKEY_new_raw_private_key()\fR.

If \fBfilename\fR is \s-1NULL\s0 the standard OpenSSL configuration file is used. If \fBappname\fR is \&\s-1NULL\s0 the standard OpenSSL application name \fBopenssl_conf\fR is used. The behaviour can be customized using \fBflags\fR. .PP \&\fBCONF_modules_load()\fR is identical to \fBCONF_modules_load_file()\fR except it reads configuration information from \fBcnf\fR. .SH "NOTES" .IX Header "NOTES" The following \fBflags\fR are currently recognized: .PP If \fB\s-1CONF_MFLAGS_IGNORE_ERRORS\s0\fR is set errors returned by individual configuration modules are ignored. If not set the first module error is considered fatal and no further modules are loaded. .PP Normally any modules errors will add error information to the error queue. If \&\fB\s-1CONF_MFLAGS_SILENT\s0\fR is set no error information is added. .PP If \fB\s-1CONF_MFLAGS_IGNORE_RETURN_CODES\s0\fR is set the function unconditionally returns success. This is used by default in \fBOPENSSL_init_crypto\fR\|(3) to ignore any errors in the default system-wide configuration file, as having all OpenSSL applications fail to start when there are potentially minor issues in the file is too risky. Applications calling \fBCONF_modules_load_file\fR explicitly should not generally set this flag. .PP If \fB\s-1CONF_MFLAGS_NO_DSO\s0\fR is set configuration module loading from DSOs is disabled. .PP \&\fB\s-1CONF_MFLAGS_IGNORE_MISSING_FILE\s0\fR if set will make \fBCONF_load_modules_file()\fR ignore missing configuration files. Normally a missing configuration file return an error. .PP \&\fB\s-1CONF_MFLAGS_DEFAULT_SECTION\s0\fR if set and \fBappname\fR is not \s-1NULL\s0 will use the default section pointed to by \fBopenssl_conf\fR if \fBappname\fR does not exist. .PP By using \fBCONF_modules_load_file()\fR with appropriate flags an application can customise application configuration to best suit its needs. In some cases the use of a configuration file is optional and its absence is not an error: in this case \fB\s-1CONF_MFLAGS_IGNORE_MISSING_FILE\s0\fR would be set. .PP Errors during configuration may also be handled differently by different applications. For example in some cases an error may simply print out a warning message and the application continue. In other cases an application might consider a configuration file error as fatal and exit immediately. .PP Applications can use the \fBCONF_modules_load()\fR function if they wish to load a configuration file themselves and have finer control over how errors are treated. .SH "RETURN VALUES" .IX Header "RETURN VALUES" These functions return 1 for success and a zero or negative value for failure.

Every \s-1ASN1\s0 object as a global variable, TYPE_it, that describes the item such as its fields. (On systems which cannot export variables from shared libraries, the global is instead a function which returns a pointer to a static variable. .PP The macro \s-1\fBDECLARE_ASN1_FUNCTIONS\s0()\fR is typically used in header files to generate the function declarations. .PP The macro \s-1\fBIMPLEMENT_ASN1_FUNCTIONS\s0()\fR is used once in a source file to generate the function bodies. .PP \&\fBTYPE_new()\fR allocates an empty object of the indicated type. The object returned must be released by calling \fBTYPE_free()\fR. .PP \&\fBTYPE_dup()\fR copies an existing object. .PP \&\fBTYPE_free()\fR releases the object and all pointers and sub-objects within it. .PP \&\fBTYPE_print_ctx()\fR prints the object \fBa\fR on the specified \s-1BIO\s0 \fBout\fR. Each line will be prefixed with \fBindent\fR spaces. The \fBpctx\fR specifies the printing context and is for internal use; use \s-1NULL\s0 to get the default behavior.

Note that the \fBq\fR parameter is optional. It also contains a public key (\fBpub_key\fR) and (optionally) a private key (\fBpriv_key\fR). .PP The \fBp\fR, \fBq\fR and \fBg\fR parameters can be obtained by calling \fBDH_get0_pqg()\fR. If the parameters have not yet been set then \fB*p\fR, \fB*q\fR and \fB*g\fR will be set to \s-1NULL.\s0 Otherwise they are set to pointers to their respective values. These point directly to the internal representations of the values and therefore should not be freed directly. Any of the out parameters \fBp\fR, \fBq\fR, and \fBg\fR can be \s-1NULL,\s0 in which case no value will be returned for that parameter. .PP The \fBp\fR, \fBq\fR and \fBg\fR values can be set by calling \fBDH_set0_pqg()\fR and passing the new values for \fBp\fR, \fBq\fR and \fBg\fR as parameters to the function. Calling this function transfers the memory management of the values to the \s-1DH\s0 object, and therefore the values that have been passed in should not be freed directly after this function has been called. The \fBq\fR parameter may be \s-1NULL.\s0 .PP To get the public and private key values use the \fBDH_get0_key()\fR function. A pointer to the public key will be stored in \fB*pub_key\fR, and a pointer to the private key will be stored in \fB*priv_key\fR. Either may be \s-1NULL\s0 if they have not been set yet, although if the private key has been set then the public key must be. The values point to the internal representation of the public key and private key values. This memory should not be freed directly. Any of the out parameters \fBpub_key\fR and \fBpriv_key\fR can be \s-1NULL,\s0 in which case no value will be returned for that parameter. .PP The public and private key values can be set using \fBDH_set0_key()\fR. Either parameter may be \s-1NULL,\s0 which means the corresponding \s-1DH\s0 field is left untouched. As with \fBDH_set0_pqg()\fR this function transfers the memory management of the key values to the \s-1DH\s0 object, and therefore they should not be freed directly after this function has been called. .PP Any of the values \fBp\fR, \fBq\fR, \fBg\fR, \fBpriv_key\fR, and \fBpub_key\fR can also be retrieved separately by the corresponding function \fBDH_get0_p()\fR, \fBDH_get0_q()\fR, \&\fBDH_get0_g()\fR, \fBDH_get0_priv_key()\fR, and \fBDH_get0_pub_key()\fR, respectively. .PP \&\fBDH_set_flags()\fR sets the flags in the \fBflags\fR parameter on the \s-1DH\s0 object. Multiple flags can be passed in one go (bitwise ORed together). Any flags that are already set are left set. \fBDH_test_flags()\fR tests to see whether the flags passed in the \fBflags\fR parameter are currently set in the \s-1DH\s0 object. Multiple flags can be tested in one go. All flags that are currently set are returned, or zero if none of the flags are set. \fBDH_clear_flags()\fR clears the specified flags within the \s-1DH\s0 object. .PP \&\fBDH_get0_engine()\fR returns a handle to the \s-1ENGINE\s0 that has been set for this \s-1DH\s0 object, or \s-1NULL\s0 if no such \s-1ENGINE\s0 has been set. .PP The \fBDH_get_length()\fR and \fBDH_set_length()\fR functions get and set the optional length parameter associated with this \s-1DH\s0 object. If the length is nonzero then it is used, otherwise it is ignored. The \fBlength\fR parameter indicates the length of the secret exponent (private key) in bits. .SH "NOTES" .IX Header "NOTES" Values retrieved with \fBDH_get0_key()\fR are owned by the \s-1DH\s0 object used in the call and may therefore \fInot\fR be passed to \fBDH_set0_key()\fR. If needed, duplicate the received value using \fBBN_dup()\fR and pass the duplicate. The same applies to \fBDH_get0_pqg()\fR and \fBDH_set0_pqg()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBDH_set0_pqg()\fR and \fBDH_set0_key()\fR return 1 on success or 0 on failure. .PP \&\fBDH_get0_p()\fR, \fBDH_get0_q()\fR, \fBDH_get0_g()\fR, \fBDH_get0_priv_key()\fR, and \fBDH_get0_pub_key()\fR return the respective value, or \s-1NULL\s0 if it is unset. .PP \&\fBDH_test_flags()\fR returns the current state of the flags in the \s-1DH\s0 object. .PP \&\fBDH_get0_engine()\fR returns the \s-1ENGINE\s0 set for the \s-1DH\s0 object or \s-1NULL\s0 if no \s-1ENGINE\s0 has been set. .PP \&\fBDH_get_length()\fR returns the length of the secret exponent (private key) in bits, or zero if no such length has been explicitly set. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBDH_new\fR\|(3), \fBDH_new\fR\|(3), \fBDH_generate_parameters\fR\|(3), \fBDH_generate_key\fR\|(3), \&\fBDH_set_method\fR\|(3), \fBDH_size\fR\|(3), \fBDH_meth_new\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The functions described here were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2020 The OpenSSL Project Authors.

It provides a set of functions used by OpenSSL for the implementation of the various \s-1DH\s0 capabilities. .PP \&\fBDH_meth_new()\fR creates a new \fB\s-1DH_METHOD\s0\fR structure. It should be given a unique \fBname\fR and a set of \fBflags\fR. The \fBname\fR should be a \s-1NULL\s0 terminated string, which will be duplicated and stored in the \fB\s-1DH_METHOD\s0\fR object. It is the callers responsibility to free the original string. The flags will be used during the construction of a new \fB\s-1DH\s0\fR object based on this \fB\s-1DH_METHOD\s0\fR. Any new \fB\s-1DH\s0\fR object will have those flags set by default. .PP \&\fBDH_meth_dup()\fR creates a duplicate copy of the \fB\s-1DH_METHOD\s0\fR object passed as a parameter. This might be useful for creating a new \fB\s-1DH_METHOD\s0\fR based on an existing one, but with some differences. .PP \&\fBDH_meth_free()\fR destroys a \fB\s-1DH_METHOD\s0\fR structure and frees up any memory associated with it. .PP \&\fBDH_meth_get0_name()\fR will return a pointer to the name of this \s-1DH_METHOD.\s0 This is a pointer to the internal name string and so should not be freed by the caller. \fBDH_meth_set1_name()\fR sets the name of the \s-1DH_METHOD\s0 to \fBname\fR. The string is duplicated and the copy is stored in the \s-1DH_METHOD\s0 structure, so the caller remains responsible for freeing the memory associated with the name. .PP \&\fBDH_meth_get_flags()\fR returns the current value of the flags associated with this \&\s-1DH_METHOD.\s0 \fBDH_meth_set_flags()\fR provides the ability to set these flags. .PP The functions \fBDH_meth_get0_app_data()\fR and \fBDH_meth_set0_app_data()\fR provide the ability to associate implementation specific data with the \s-1DH_METHOD.\s0 It is the application's responsibility to free this data before the \s-1DH_METHOD\s0 is freed via a call to \fBDH_meth_free()\fR. .PP \&\fBDH_meth_get_generate_key()\fR and \fBDH_meth_set_generate_key()\fR get and set the function used for generating a new \s-1DH\s0 key pair respectively. This function will be called in response to the application calling \fBDH_generate_key()\fR. The parameter for the function has the same meaning as for \fBDH_generate_key()\fR. .PP \&\fBDH_meth_get_compute_key()\fR and \fBDH_meth_set_compute_key()\fR get and set the function used for computing a new \s-1DH\s0 shared secret respectively. This function will be called in response to the application calling \fBDH_compute_key()\fR. The parameters for the function have the same meaning as for \fBDH_compute_key()\fR. .PP \&\fBDH_meth_get_bn_mod_exp()\fR and \fBDH_meth_set_bn_mod_exp()\fR get and set the function used for computing the following value: .PP .Vb 1 \& r = a ^ p mod m .Ve .PP This function will be called by the default OpenSSL function for \&\fBDH_generate_key()\fR. The result is stored in the \fBr\fR parameter. This function may be \s-1NULL\s0 unless using the default generate key function, in which case it must be present. .PP \&\fBDH_meth_get_init()\fR and \fBDH_meth_set_init()\fR get and set the function used for creating a new \s-1DH\s0 instance respectively. This function will be called in response to the application calling \fBDH_new()\fR (if the current default \&\s-1DH_METHOD\s0 is this one) or \fBDH_new_method()\fR. The \fBDH_new()\fR and \fBDH_new_method()\fR functions will allocate the memory for the new \s-1DH\s0 object, and a pointer to this newly allocated structure will be passed as a parameter to the function. This function may be \s-1NULL.\s0 .PP \&\fBDH_meth_get_finish()\fR and \fBDH_meth_set_finish()\fR get and set the function used for destroying an instance of a \s-1DH\s0 object respectively. This function will be called in response to the application calling \fBDH_free()\fR. A pointer to the \s-1DH\s0 to be destroyed is passed as a parameter. The destroy function should be used for \s-1DH\s0 implementation specific clean up. The memory for the \s-1DH\s0 itself should not be freed by this function. This function may be \s-1NULL.\s0 .PP \&\fBDH_meth_get_generate_params()\fR and \fBDH_meth_set_generate_params()\fR get and set the function used for generating \s-1DH\s0 parameters respectively. This function will be called in response to the application calling \fBDH_generate_parameters_ex()\fR (or \&\fBDH_generate_parameters()\fR). The parameters for the function have the same meaning as for \fBDH_generate_parameters_ex()\fR. This function may be \s-1NULL.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBDH_meth_new()\fR and \fBDH_meth_dup()\fR return the newly allocated \s-1DH_METHOD\s0 object or \s-1NULL\s0 on failure. .PP \&\fBDH_meth_get0_name()\fR and \fBDH_meth_get_flags()\fR return the name and flags associated with the \s-1DH_METHOD\s0 respectively. .PP All other DH_meth_get_*() functions return the appropriate function pointer that has been set in the \s-1DH_METHOD,\s0 or \s-1NULL\s0 if no such pointer has yet been set. .PP \&\fBDH_meth_set1_name()\fR and all DH_meth_set_*() functions return 1 on success or 0 on failure. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBDH_new\fR\|(3), \fBDH_new\fR\|(3), \fBDH_generate_parameters\fR\|(3), \fBDH_generate_key\fR\|(3), \&\fBDH_set_method\fR\|(3), \fBDH_size\fR\|(3), \fBDH_get0_pqg\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The functions described here were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2018 The OpenSSL Project Authors.

These parameters include the \fBgenerator\fR, the \fBorder\fR and the \fBcofactor\fR. The \fBgenerator\fR is a well defined point on the curve chosen for cryptographic operations. Integers used for point multiplications will be between 0 and n\-1 where n is the \fBorder\fR. The \fBorder\fR multiplied by the \fBcofactor\fR gives the number of points on the curve. .PP \&\fBEC_GROUP_get0_generator()\fR returns the generator for the identified \fBgroup\fR. .PP \&\fBEC_GROUP_get_order()\fR retrieves the order of \fBgroup\fR and copies its value into \&\fBorder\fR.

It fails in case \fBgroup\fR is not fully initialized or if the cofactor is not set (or set to zero). .PP The functions \fBEC_GROUP_set_curve_name()\fR and \fBEC_GROUP_get_curve_name()\fR, set and get the \s-1NID\s0 for the curve respectively (see \fBEC_GROUP_new\fR\|(3)). If a curve does not have a \s-1NID\s0 associated with it, then EC_GROUP_get_curve_name will return NID_undef. .PP The asn1_flag value is used to determine whether the curve encoding uses explicit parameters or a named curve using an \s-1ASN1 OID:\s0 many applications only support the latter form. If asn1_flag is \fB\s-1OPENSSL_EC_NAMED_CURVE\s0\fR then the named curve form is used and the parameters must have a corresponding named curve \s-1NID\s0 set. If asn1_flags is \fB\s-1OPENSSL_EC_EXPLICIT_CURVE\s0\fR the parameters are explicitly encoded. The functions \fBEC_GROUP_get_asn1_flag()\fR and \&\fBEC_GROUP_set_asn1_flag()\fR get and set the status of the asn1_flag for the curve. Note: \fB\s-1OPENSSL_EC_EXPLICIT_CURVE\s0\fR was added in OpenSSL 1.1.0, for previous versions of OpenSSL the value 0 must be used instead. Before OpenSSL 1.1.0 the default form was to use explicit parameters (meaning that applications would have to explicitly set the named curve form) in OpenSSL 1.1.0 and later the named curve form is the default. .PP The point_conversion_form for a curve controls how \s-1EC_POINT\s0 data is encoded as \s-1ASN1\s0 as defined in X9.62 (\s-1ECDSA\s0). point_conversion_form_t is an enum defined as follows: .PP .Vb 10 \& typedef enum { \& /** the point is encoded as z||x, where the octet z specifies \& * which solution of the quadratic equation y is */ \& POINT_CONVERSION_COMPRESSED = 2, \& /** the point is encoded as z||x||y, where z is the octet 0x04 */ \& POINT_CONVERSION_UNCOMPRESSED = 4, \& /** the point is encoded as z||x||y, where the octet z specifies \& * which solution of the quadratic equation y is */ \& POINT_CONVERSION_HYBRID = 6 \& } point_conversion_form_t; .Ve .PP For \s-1POINT_CONVERSION_UNCOMPRESSED\s0 the point is encoded as an octet signifying the \s-1UNCOMPRESSED\s0 form has been used followed by the octets for x, followed by the octets for y. .PP For any given x co-ordinate for a point on a curve it is possible to derive two possible y values. For \&\s-1POINT_CONVERSION_COMPRESSED\s0 the point is encoded as an octet signifying that the \s-1COMPRESSED\s0 form has been used \s-1AND\s0 which of the two possible solutions for y has been used, followed by the octets for x. .PP For \s-1POINT_CONVERSION_HYBRID\s0 the point is encoded as an octet signifying the \s-1HYBRID\s0 form has been used \s-1AND\s0 which of the two possible solutions for y has been used, followed by the octets for x, followed by the octets for y. .PP The functions \fBEC_GROUP_set_point_conversion_form()\fR and \fBEC_GROUP_get_point_conversion_form()\fR, set and get the point_conversion_form for the curve respectively. .PP \&\s-1ANSI X9.62\s0 (\s-1ECDSA\s0 standard) defines a method of generating the curve parameter b from a random number. This provides advantages in that a parameter obtained in this way is highly unlikely to be susceptible to special purpose attacks, or have any trapdoors in it. If the seed is present for a curve then the b parameter was generated in a verifiable fashion using that seed. The OpenSSL \s-1EC\s0 library does not use this seed value but does enable you to inspect it using \fBEC_GROUP_get0_seed()\fR. This returns a pointer to a memory block containing the seed that was used. The length of the memory block can be obtained using \fBEC_GROUP_get_seed_len()\fR. A number of the built-in curves within the library provide seed values that can be obtained. It is also possible to set a custom seed using \&\fBEC_GROUP_set_seed()\fR and passing a pointer to a memory block, along with the length of the seed. Again, the \s-1EC\s0 library will not use this seed value, although it will be preserved in any \s-1ASN1\s0 based communications. .PP \&\fBEC_GROUP_get_degree()\fR gets the degree of the field. For Fp fields this will be the number of bits in p. For F2^m fields this will be the value m. .PP The function \fBEC_GROUP_check_discriminant()\fR calculates the discriminant for the curve and verifies that it is valid. For a curve defined over Fp the discriminant is given by the formula 4*a^3 + 27*b^2 whilst for F2^m curves the discriminant is simply b. In either case for the curve to be valid the discriminant must be non zero. .PP The function \fBEC_GROUP_check()\fR performs a number of checks on a curve to verify that it is valid. Checks performed include verifying that the discriminant is non zero; that a generator has been defined; that the generator is on the curve and has the correct order. .PP \&\fBEC_GROUP_cmp()\fR compares \fBa\fR and \fBb\fR to determine whether they represent the same curve or not. .PP The functions \fBEC_GROUP_get_basis_type()\fR, \fBEC_GROUP_get_trinomial_basis()\fR and \fBEC_GROUP_get_pentanomial_basis()\fR should only be called for curves defined over an F2^m field. Addition and multiplication operations within an F2^m field are performed using an irreducible polynomial function f(x). This function is either a trinomial of the form: .PP f(x) = x^m + x^k + 1 with m > k >= 1 .PP or a pentanomial of the form: .PP f(x) = x^m + x^k3 + x^k2 + x^k1 + 1 with m > k3 > k2 > k1 >= 1 .PP The function \fBEC_GROUP_get_basis_type()\fR returns a \s-1NID\s0 identifying whether a trinomial or pentanomial is in use for the field. The function \fBEC_GROUP_get_trinomial_basis()\fR must only be called where f(x) is of the trinomial form, and returns the value of \fBk\fR. Similarly the function \fBEC_GROUP_get_pentanomial_basis()\fR must only be called where f(x) is of the pentanomial form, and returns the values of \fBk1\fR, \&\fBk2\fR and \fBk3\fR respectively. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following functions return 1 on success or 0 on error: \fBEC_GROUP_copy()\fR, \fBEC_GROUP_set_generator()\fR, \fBEC_GROUP_check()\fR, \&\fBEC_GROUP_check_discriminant()\fR, \fBEC_GROUP_get_trinomial_basis()\fR and \fBEC_GROUP_get_pentanomial_basis()\fR. .PP \&\fBEC_GROUP_dup()\fR returns a pointer to the duplicated curve, or \s-1NULL\s0 on error. .PP \&\fBEC_GROUP_method_of()\fR returns the \s-1EC_METHOD\s0 implementation in use for the given curve or \s-1NULL\s0 on error. .PP \&\fBEC_GROUP_get0_generator()\fR returns the generator for the given curve or \s-1NULL\s0 on error. .PP \&\fBEC_GROUP_get_order()\fR returns 0 if the order is not set (or set to zero) for \&\fBgroup\fR or if copying into \fBorder\fR fails, 1 otherwise. .PP \&\fBEC_GROUP_get_cofactor()\fR returns 0 if the cofactor is not set (or is set to zero) for \fBgroup\fR or if copying into \fBcofactor\fR fails, 1 otherwise. .PP \&\fBEC_GROUP_get_curve_name()\fR returns the curve name (\s-1NID\s0) for \fBgroup\fR or will return NID_undef if no curve name is associated. .PP \&\fBEC_GROUP_get_asn1_flag()\fR returns the \s-1ASN1\s0 flag for the specified \fBgroup\fR . .PP \&\fBEC_GROUP_get_point_conversion_form()\fR returns the point_conversion_form for \fBgroup\fR. .PP \&\fBEC_GROUP_get_degree()\fR returns the degree for \fBgroup\fR or 0 if the operation is not supported by the underlying group implementation. .PP \&\fBEC_GROUP_get0_order()\fR returns an internal pointer to the group order. \&\fBEC_GROUP_order_bits()\fR returns the number of bits in the group order. \&\fBEC_GROUP_get0_cofactor()\fR returns an internal pointer to the group cofactor. .PP \&\fBEC_GROUP_get0_seed()\fR returns a pointer to the seed that was used to generate the parameter b, or \s-1NULL\s0 if the seed is not specified. \fBEC_GROUP_get_seed_len()\fR returns the length of the seed or 0 if the seed is not specified. .PP \&\fBEC_GROUP_set_seed()\fR returns the length of the seed that has been set.

The \fBdigest_custom()\fR function will be called by \fBEVP_DigestSignInit\fR\|(3) and \fBEVP_DigestVerifyInit\fR\|(3). .SS "Functions" .IX Subsection "Functions" \&\fBEVP_PKEY_meth_new()\fR creates and returns a new \fB\s-1EVP_PKEY_METHOD\s0\fR object, and associates the given \fBid\fR and \fBflags\fR.

This function first searches through the user-defined method objects and then the built-in objects. .PP \&\fBEVP_PKEY_meth_add0()\fR adds \fBpmeth\fR to the user defined stack of methods. .PP \&\fBEVP_PKEY_meth_remove()\fR removes an \fB\s-1EVP_PKEY_METHOD\s0\fR object added by \&\fBEVP_PKEY_meth_add0()\fR. .PP The EVP_PKEY_meth_set functions set the corresponding fields of \&\fB\s-1EVP_PKEY_METHOD\s0\fR structure with the arguments passed. .PP The EVP_PKEY_meth_get functions get the corresponding fields of \&\fB\s-1EVP_PKEY_METHOD\s0\fR structure to the arguments provided. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_PKEY_meth_new()\fR returns a pointer to a new \fB\s-1EVP_PKEY_METHOD\s0\fR object or returns \s-1NULL\s0 on error. .PP \&\fBEVP_PKEY_meth_free()\fR and \fBEVP_PKEY_meth_copy()\fR do not return values. .PP \&\fBEVP_PKEY_meth_find()\fR returns a pointer to the found \fB\s-1EVP_PKEY_METHOD\s0\fR object or returns \s-1NULL\s0 if not found. .PP \&\fBEVP_PKEY_meth_add0()\fR returns 1 if method is added successfully or 0 if an error occurred. .PP \&\fBEVP_PKEY_meth_remove()\fR returns 1 if method is removed successfully or 0 if an error occurred. .PP All EVP_PKEY_meth_set and EVP_PKEY_meth_get functions have no return values.

This function can be called several times on the same \fBctx\fR to include additional data. This function is currently implemented using a macro. .PP \&\fBEVP_DigestSignFinal()\fR signs the data in \fBctx\fR and places the signature in \fBsig\fR. If \fBsig\fR is \fB\s-1NULL\s0\fR then the maximum size of the output buffer is written to the \fBsiglen\fR parameter. If \fBsig\fR is not \fB\s-1NULL\s0\fR then before the call the \&\fBsiglen\fR parameter should contain the length of the \fBsig\fR buffer. If the call is successful the signature is written to \fBsig\fR and the amount of data written to \fBsiglen\fR. .PP \&\fBEVP_DigestSign()\fR signs \fBtbslen\fR bytes of data at \fBtbs\fR and places the signature in \fBsig\fR and its length in \fBsiglen\fR in a similar way to \&\fBEVP_DigestSignFinal()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_DigestSignInit()\fR, \fBEVP_DigestSignUpdate()\fR, \fBEVP_DigestSignFinal()\fR and \&\fBEVP_DigestSign()\fR return 1 for success and 0 for failure. .PP The error codes can be obtained from \fBERR_get_error\fR\|(3). .SH "NOTES" .IX Header "NOTES" The \fB\s-1EVP\s0\fR interface to digital signatures should almost always be used in preference to the low-level interfaces. This is because the code then becomes transparent to the algorithm used and much more flexible. .PP \&\fBEVP_DigestSign()\fR is a one shot operation which signs a single block of data in one function. For algorithms that support streaming it is equivalent to calling \fBEVP_DigestSignUpdate()\fR and \fBEVP_DigestSignFinal()\fR. For algorithms which do not support streaming (e.g. PureEdDSA) it is the only way to sign data. .PP In previous versions of OpenSSL there was a link between message digest types and public key algorithms. This meant that \*(L"clone\*(R" digests such as \fBEVP_dss1()\fR needed to be used to sign using \s-1SHA1\s0 and \s-1DSA.\s0 This is no longer necessary and the use of clone digest is now discouraged. .PP For some key types and parameters the random number generator must be seeded. If the automatic seeding or reseeding of the OpenSSL \s-1CSPRNG\s0 fails due to external circumstances (see \s-1\fBRAND\s0\fR\|(7)), the operation will fail. .PP The call to \fBEVP_DigestSignFinal()\fR internally finalizes a copy of the digest context. This means that calls to \fBEVP_DigestSignUpdate()\fR and \&\fBEVP_DigestSignFinal()\fR can be called later to digest and sign additional data. .PP Since only a copy of the digest context is ever finalized, the context must be cleaned up after use by calling \fBEVP_MD_CTX_free()\fR or a memory leak will occur. .PP The use of \fBEVP_PKEY_size()\fR with these functions is discouraged because some signature operations may have a signature length which depends on the parameters set. As a result \fBEVP_PKEY_size()\fR would have to return a value which indicates the maximum possible signature for any set of parameters. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_DigestVerifyInit\fR\|(3), \&\fBEVP_DigestInit\fR\|(3), \&\fBevp\fR\|(7), \s-1\fBHMAC\s0\fR\|(3), \s-1\fBMD2\s0\fR\|(3), \&\s-1\fBMD5\s0\fR\|(3), \s-1\fBMDC2\s0\fR\|(3), \s-1\fBRIPEMD160\s0\fR\|(3), \&\s-1\fBSHA1\s0\fR\|(3), \fBdgst\fR\|(1), \&\s-1\fBRAND\s0\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" \&\fBEVP_DigestSignInit()\fR, \fBEVP_DigestSignUpdate()\fR and \fBEVP_DigestSignFinal()\fR were added in OpenSSL 1.0.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2006\-2020 The OpenSSL Project Authors.

By modifying the method, alternative implementations such as hardware accelerators may be used. \s-1IMPORTANT:\s0 See the \s-1NOTES\s0 section for important information about how these \s-1DSA API\s0 functions are affected by the use of \fB\s-1ENGINE\s0\fR \s-1API\s0 calls. .PP Initially, the default \s-1DSA_METHOD\s0 is the OpenSSL internal implementation, as returned by \fBDSA_OpenSSL()\fR. .PP \&\fBDSA_set_default_method()\fR makes \fBmeth\fR the default method for all \s-1DSA\s0 structures created later. \&\fB\s-1NB\s0\fR: This is true only whilst no \s-1ENGINE\s0 has been set as a default for \s-1DSA,\s0 so this function is no longer recommended. This function is not thread-safe and should not be called at the same time as other OpenSSL functions. .PP \&\fBDSA_get_default_method()\fR returns a pointer to the current default \&\s-1DSA_METHOD.\s0 However, the meaningfulness of this result is dependent on whether the \s-1ENGINE API\s0 is being used, so this function is no longer recommended. .PP \&\fBDSA_set_method()\fR selects \fBmeth\fR to perform all operations using the key \&\fBrsa\fR. This will replace the \s-1DSA_METHOD\s0 used by the \s-1DSA\s0 key and if the previous method was supplied by an \s-1ENGINE,\s0 the handle to that \s-1ENGINE\s0 will be released during the change. It is possible to have \s-1DSA\s0 keys that only work with certain \s-1DSA_METHOD\s0 implementations (e.g. from an \s-1ENGINE\s0 module that supports embedded hardware-protected keys), and in such cases attempting to change the \s-1DSA_METHOD\s0 for the key can have unexpected results. See DSA_meth_new for information on constructing custom \s-1DSA_METHOD\s0 objects; .PP \&\fBDSA_new_method()\fR allocates and initializes a \s-1DSA\s0 structure so that \fBengine\fR will be used for the \s-1DSA\s0 operations. If \fBengine\fR is \s-1NULL,\s0 the default engine for \s-1DSA\s0 operations is used, and if no default \s-1ENGINE\s0 is set, the \s-1DSA_METHOD\s0 controlled by \fBDSA_set_default_method()\fR is used. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBDSA_OpenSSL()\fR and \fBDSA_get_default_method()\fR return pointers to the respective \&\fB\s-1DSA_METHOD\s0\fRs. .PP \&\fBDSA_set_default_method()\fR returns no value. .PP \&\fBDSA_set_method()\fR returns nonzero if the provided \fBmeth\fR was successfully set as the method for \fBdsa\fR (including unloading the \s-1ENGINE\s0 handle if the previous method was supplied by an \s-1ENGINE\s0). .PP \&\fBDSA_new_method()\fR returns \s-1NULL\s0 and sets an error code that can be obtained by \fBERR_get_error\fR\|(3) if the allocation fails.

The \fBcontext\fR value determines which messages and under what conditions the extension will be added/parsed (see the \*(L"\s-1EXTENSION CONTEXTS\*(R"\s0 section below). .PP \&\fBSSL_CTX_add_client_custom_ext()\fR adds a custom extension for a \s-1TLS/DTLS\s0 client with extension type \fBext_type\fR and callbacks \fBadd_cb\fR, \fBfree_cb\fR and \&\fBparse_cb\fR. This function is similar to \fBSSL_CTX_add_custom_ext()\fR except it only applies to clients, uses the older style of callbacks, and implicitly sets the \&\fBcontext\fR value to: .PP .Vb 2 \& SSL_EXT_TLS1_2_AND_BELOW_ONLY | SSL_EXT_CLIENT_HELLO \& | SSL_EXT_TLS1_2_SERVER_HELLO | SSL_EXT_IGNORE_ON_RESUMPTION .Ve .PP \&\fBSSL_CTX_add_server_custom_ext()\fR adds a custom extension for a \s-1TLS/DTLS\s0 server with extension type \fBext_type\fR and callbacks \fBadd_cb\fR, \fBfree_cb\fR and \&\fBparse_cb\fR. This function is similar to \fBSSL_CTX_add_custom_ext()\fR except it only applies to servers, uses the older style of callbacks, and implicitly sets the \fBcontext\fR value to the same as for \fBSSL_CTX_add_client_custom_ext()\fR above. .PP The \fBext_type\fR parameter corresponds to the \fBextension_type\fR field of \&\s-1RFC5246\s0 et al. It is \fBnot\fR a \s-1NID.\s0 In all cases the extension type must not be handled by OpenSSL internally or an error occurs. .PP \&\fBSSL_extension_supported()\fR returns 1 if the extension \fBext_type\fR is handled internally by OpenSSL and 0 otherwise. .SH "EXTENSION CALLBACKS" .IX Header "EXTENSION CALLBACKS" The callback \fBadd_cb\fR is called to send custom extension data to be included in various \s-1TLS\s0 messages. The \fBext_type\fR parameter is set to the extension type which will be added and \fBadd_arg\fR to the value set when the extension handler was added. When using the new style callbacks the \fBcontext\fR parameter will indicate which message is currently being constructed e.g. for the ClientHello it will be set to \fB\s-1SSL_EXT_CLIENT_HELLO\s0\fR. .PP If the application wishes to include the extension \fBext_type\fR it should set \fB*out\fR to the extension data, set \fB*outlen\fR to the length of the extension data and return 1. .PP If the \fBadd_cb\fR does not wish to include the extension it must return 0. .PP If \fBadd_cb\fR returns \-1 a fatal handshake error occurs using the \s-1TLS\s0 alert value specified in \fB*al\fR. .PP When constructing the ClientHello, if \fBadd_cb\fR is set to \s-1NULL\s0 a zero length extension is added for \fBext_type\fR. For all other messages if \fBadd_cb\fR is set to \s-1NULL\s0 then no extension is added. .PP When constructing a Certificate message the callback will be called for each certificate in the message. The \fBx\fR parameter will indicate the current certificate and the \fBchainidx\fR parameter will indicate the position of the certificate in the message. The first certificate is always the end entity certificate and has a \fBchainidx\fR value of 0. The certificates are in the order that they were received in the Certificate message. .PP For all messages except the ServerHello and EncryptedExtensions every registered \fBadd_cb\fR is always called to see if the application wishes to add an extension (as long as all requirements of the specified \fBcontext\fR are met). .PP For the ServerHello and EncryptedExtension messages every registered \fBadd_cb\fR is called once if and only if the requirements of the specified \fBcontext\fR are met and the corresponding extension was received in the ClientHello. That is, if no corresponding extension was received in the ClientHello then \fBadd_cb\fR will not be called. .PP If an extension is added (that is \fBadd_cb\fR returns 1) \fBfree_cb\fR is called (if it is set) with the value of \fBout\fR set by the add callback. It can be used to free up any dynamic extension data set by \fBadd_cb\fR. Since \fBout\fR is constant (to permit use of constant data in \fBadd_cb\fR) applications may need to cast away const to free the data. .PP The callback \fBparse_cb\fR receives data for \s-1TLS\s0 extensions. The callback is only called if the extension is present and relevant for the context (see \&\*(L"\s-1EXTENSION CONTEXTS\*(R"\s0 below). .PP The extension data consists of \fBinlen\fR bytes in the buffer \fBin\fR for the extension \fBext_type\fR. .PP If the message being parsed is a TLSv1.3 compatible Certificate message then \&\fBparse_cb\fR will be called for each certificate contained within the message. The \fBx\fR parameter will indicate the current certificate and the \fBchainidx\fR parameter will indicate the position of the certificate in the message. The first certificate is always the end entity certificate and has a \fBchainidx\fR value of 0. .PP If the \fBparse_cb\fR considers the extension data acceptable it must return 1. If it returns 0 or a negative value a fatal handshake error occurs using the \s-1TLS\s0 alert value specified in \fB*al\fR. .PP The buffer \fBin\fR is a temporary internal buffer which will not be valid after the callback returns. .SH "EXTENSION CONTEXTS" .IX Header "EXTENSION CONTEXTS" An extension context defines which messages and under which conditions an extension should be added or expected. The context is built up by performing a bitwise \s-1OR\s0 of multiple pre-defined values together. The valid context values are: .IP "\s-1SSL_EXT_TLS_ONLY\s0" 4 .IX Item "SSL_EXT_TLS_ONLY" The extension is only allowed in \s-1TLS\s0 .IP "\s-1SSL_EXT_DTLS_ONLY\s0" 4 .IX Item "SSL_EXT_DTLS_ONLY" The extension is only allowed in \s-1DTLS\s0 .IP "\s-1SSL_EXT_TLS_IMPLEMENTATION_ONLY\s0" 4 .IX Item "SSL_EXT_TLS_IMPLEMENTATION_ONLY" The extension is allowed in \s-1DTLS,\s0 but there is only a \s-1TLS\s0 implementation available (so it is ignored in \s-1DTLS\s0). .IP "\s-1SSL_EXT_SSL3_ALLOWED\s0" 4 .IX Item "SSL_EXT_SSL3_ALLOWED" Extensions are not typically defined for SSLv3. Setting this value will allow the extension in SSLv3. Applications will not typically need to use this. .IP "\s-1SSL_EXT_TLS1_2_AND_BELOW_ONLY\s0" 4 .IX Item "SSL_EXT_TLS1_2_AND_BELOW_ONLY" The extension is only defined for TLSv1.2/DTLSv1.2 and below.

They can, for example, be used to store the extension data received in a convenient structure or pass the extension data to be added or freed when adding extensions. .PP If the same custom extension type is received multiple times a fatal \&\fBdecode_error\fR alert is sent and the handshake aborts. If a custom extension is received in a ServerHello/EncryptedExtensions message which was not sent in the ClientHello a fatal \fBunsupported_extension\fR alert is sent and the handshake is aborted. The ServerHello/EncryptedExtensions \fBadd_cb\fR callback is only called if the corresponding extension was received in the ClientHello. This is compliant with the \s-1TLS\s0 specifications. This behaviour ensures that each callback is called at most once and that an application can never send unsolicited extensions. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_add_custom_ext()\fR, \fBSSL_CTX_add_client_custom_ext()\fR and \&\fBSSL_CTX_add_server_custom_ext()\fR return 1 for success and 0 for failure. A failure can occur if an attempt is made to add the same \fBext_type\fR more than once, if an attempt is made to use an extension type handled internally by OpenSSL or if an internal error occurs (for example a memory allocation failure). .PP \&\fBSSL_extension_supported()\fR returns 1 if the extension \fBext_type\fR is handled internally by OpenSSL and 0 otherwise. .SH "HISTORY" .IX Header "HISTORY" The \fBSSL_CTX_add_custom_ext()\fR function was added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2014\-2017 The OpenSSL Project Authors.

It provides a set of functions used by OpenSSL for the implementation of the various \s-1RSA\s0 capabilities. See the rsa page for more information. .PP \&\fBRSA_meth_new()\fR creates a new \fB\s-1RSA_METHOD\s0\fR structure. It should be given a unique \fBname\fR and a set of \fBflags\fR. The \fBname\fR should be a \&\s-1NULL\s0 terminated string, which will be duplicated and stored in the \&\fB\s-1RSA_METHOD\s0\fR object. It is the callers responsibility to free the original string. The flags will be used during the construction of a new \fB\s-1RSA\s0\fR object based on this \fB\s-1RSA_METHOD\s0\fR. Any new \fB\s-1RSA\s0\fR object will have those flags set by default. .PP \&\fBRSA_meth_dup()\fR creates a duplicate copy of the \fB\s-1RSA_METHOD\s0\fR object passed as a parameter. This might be useful for creating a new \&\fB\s-1RSA_METHOD\s0\fR based on an existing one, but with some differences. .PP \&\fBRSA_meth_free()\fR destroys an \fB\s-1RSA_METHOD\s0\fR structure and frees up any memory associated with it. .PP \&\fBRSA_meth_get0_name()\fR will return a pointer to the name of this \&\s-1RSA_METHOD.\s0 This is a pointer to the internal name string and so should not be freed by the caller. \fBRSA_meth_set1_name()\fR sets the name of the \s-1RSA_METHOD\s0 to \fBname\fR. The string is duplicated and the copy is stored in the \s-1RSA_METHOD\s0 structure, so the caller remains responsible for freeing the memory associated with the name. .PP \&\fBRSA_meth_get_flags()\fR returns the current value of the flags associated with this \s-1RSA_METHOD.\s0 \fBRSA_meth_set_flags()\fR provides the ability to set these flags. .PP The functions \fBRSA_meth_get0_app_data()\fR and \fBRSA_meth_set0_app_data()\fR provide the ability to associate implementation specific data with the \&\s-1RSA_METHOD.\s0 It is the application's responsibility to free this data before the \s-1RSA_METHOD\s0 is freed via a call to \fBRSA_meth_free()\fR. .PP \&\fBRSA_meth_get_sign()\fR and \fBRSA_meth_set_sign()\fR get and set the function used for creating an \s-1RSA\s0 signature respectively. This function will be called in response to the application calling \fBRSA_sign()\fR. The parameters for the function have the same meaning as for \fBRSA_sign()\fR. .PP \&\fBRSA_meth_get_verify()\fR and \fBRSA_meth_set_verify()\fR get and set the function used for verifying an \s-1RSA\s0 signature respectively. This function will be called in response to the application calling \&\fBRSA_verify()\fR. The parameters for the function have the same meaning as for \fBRSA_verify()\fR. .PP \&\fBRSA_meth_get_mod_exp()\fR and \fBRSA_meth_set_mod_exp()\fR get and set the function used for \s-1CRT\s0 computations. .PP \&\fBRSA_meth_get_bn_mod_exp()\fR and \fBRSA_meth_set_bn_mod_exp()\fR get and set the function used for \s-1CRT\s0 computations, specifically the following value: .PP .Vb 1 \& r = a ^ p mod m .Ve .PP Both the \fBmod_exp()\fR and \fBbn_mod_exp()\fR functions are called by the default OpenSSL method during encryption, decryption, signing and verification. .PP \&\fBRSA_meth_get_init()\fR and \fBRSA_meth_set_init()\fR get and set the function used for creating a new \s-1RSA\s0 instance respectively. This function will be called in response to the application calling \fBRSA_new()\fR (if the current default \s-1RSA_METHOD\s0 is this one) or \fBRSA_new_method()\fR. The \&\fBRSA_new()\fR and \fBRSA_new_method()\fR functions will allocate the memory for the new \s-1RSA\s0 object, and a pointer to this newly allocated structure will be passed as a parameter to the function. This function may be \&\s-1NULL.\s0 .PP \&\fBRSA_meth_get_finish()\fR and \fBRSA_meth_set_finish()\fR get and set the function used for destroying an instance of an \s-1RSA\s0 object respectively. This function will be called in response to the application calling \&\fBRSA_free()\fR. A pointer to the \s-1RSA\s0 to be destroyed is passed as a parameter. The destroy function should be used for \s-1RSA\s0 implementation specific clean up. The memory for the \s-1RSA\s0 itself should not be freed by this function. This function may be \s-1NULL.\s0 .PP \&\fBRSA_meth_get_keygen()\fR and \fBRSA_meth_set_keygen()\fR get and set the function used for generating a new \s-1RSA\s0 key pair respectively. This function will be called in response to the application calling \&\fBRSA_generate_key_ex()\fR. The parameter for the function has the same meaning as for \fBRSA_generate_key_ex()\fR. .PP \&\fBRSA_meth_get_multi_prime_keygen()\fR and \fBRSA_meth_set_multi_prime_keygen()\fR get and set the function used for generating a new multi-prime \s-1RSA\s0 key pair respectively. This function will be called in response to the application calling \&\fBRSA_generate_multi_prime_key()\fR. The parameter for the function has the same meaning as for \fBRSA_generate_multi_prime_key()\fR. .PP \&\fBRSA_meth_get_pub_enc()\fR, \fBRSA_meth_set_pub_enc()\fR, \&\fBRSA_meth_get_pub_dec()\fR, \fBRSA_meth_set_pub_dec()\fR, \&\fBRSA_meth_get_priv_enc()\fR, \fBRSA_meth_set_priv_enc()\fR, \&\fBRSA_meth_get_priv_dec()\fR, \fBRSA_meth_set_priv_dec()\fR get and set the functions used for public and private key encryption and decryption. These functions will be called in response to the application calling \&\fBRSA_public_encrypt()\fR, \fBRSA_private_decrypt()\fR, \fBRSA_private_encrypt()\fR and \&\fBRSA_public_decrypt()\fR and take the same parameters as those. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBRSA_meth_new()\fR and \fBRSA_meth_dup()\fR return the newly allocated \&\s-1RSA_METHOD\s0 object or \s-1NULL\s0 on failure. .PP \&\fBRSA_meth_get0_name()\fR and \fBRSA_meth_get_flags()\fR return the name and flags associated with the \s-1RSA_METHOD\s0 respectively. .PP All other RSA_meth_get_*() functions return the appropriate function pointer that has been set in the \s-1RSA_METHOD,\s0 or \s-1NULL\s0 if no such pointer has yet been set. .PP RSA_meth_set1_name and all RSA_meth_set_*() functions return 1 on success or 0 on failure. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBRSA_new\fR\|(3), \fBRSA_generate_key_ex\fR\|(3), \fBRSA_sign\fR\|(3), \&\fBRSA_set_method\fR\|(3), \fBRSA_size\fR\|(3), \fBRSA_get0_key\fR\|(3), \&\fBRSA_generate_multi_prime_key\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fBRSA_meth_get_multi_prime_keygen()\fR and \fBRSA_meth_set_multi_prime_keygen()\fR were added in OpenSSL 1.1.1. .PP Other functions described here were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2018 The OpenSSL Project Authors.

They constitute a promise by a Certificate Transparency (\s-1CT\s0) log to publicly record a certificate. By cryptographically verifying that a log did indeed issue an \s-1SCT,\s0 some confidence can be gained that the certificate is publicly known. .PP An internal representation of an \s-1SCT\s0 can be created in one of two ways. The first option is to create a blank \s-1SCT,\s0 using \fBSCT_new()\fR, and then populate it using: .IP "\(bu" 2 \&\fBSCT_set_version()\fR to set the \s-1SCT\s0 version. .Sp Only \s-1SCT_VERSION_V1\s0 is currently supported. .IP "\(bu" 2 \&\fBSCT_set_log_entry_type()\fR to set the type of certificate the \s-1SCT\s0 was issued for: .Sp \&\fB\s-1CT_LOG_ENTRY_TYPE_X509\s0\fR for a normal certificate. \&\fB\s-1CT_LOG_ENTRY_TYPE_PRECERT\s0\fR for a pre-certificate. .IP "\(bu" 2 \&\fBSCT_set0_log_id()\fR or \fBSCT_set1_log_id()\fR to set the LogID of the \s-1CT\s0 log that the \s-1SCT\s0 came from. .Sp The former takes ownership, whereas the latter makes a copy. See \s-1RFC 6962,\s0 Section 3.2 for the definition of LogID. .IP "\(bu" 2 \&\fBSCT_set_timestamp()\fR to set the time the \s-1SCT\s0 was issued (epoch time in milliseconds). .IP "\(bu" 2 \&\fBSCT_set_signature_nid()\fR to set the \s-1NID\s0 of the signature. .IP "\(bu" 2 \&\fBSCT_set0_signature()\fR or \fBSCT_set1_signature()\fR to set the raw signature value. .Sp The former takes ownership, whereas the latter makes a copy. .IP "\(bu" 2 \&\fBSCT_set0_extensions()\fR or \fBSCT_set1_extensions\fR to provide \s-1SCT\s0 extensions. .Sp The former takes ownership, whereas the latter makes a copy. .PP Alternatively, the \s-1SCT\s0 can be pre-populated from the following data using \&\fBSCT_new_from_base64()\fR: .IP "\(bu" 2 The \s-1SCT\s0 version (only \s-1SCT_VERSION_V1\s0 is currently supported). .IP "\(bu" 2 The LogID (see \s-1RFC 6962,\s0 Section 3.2), base64 encoded. .IP "\(bu" 2 The type of certificate the \s-1SCT\s0 was issued for: \&\fB\s-1CT_LOG_ENTRY_TYPE_X509\s0\fR for a normal certificate. \&\fB\s-1CT_LOG_ENTRY_TYPE_PRECERT\s0\fR for a pre-certificate. .IP "\(bu" 2 The time that the \s-1SCT\s0 was issued (epoch time in milliseconds). .IP "\(bu" 2 The \s-1SCT\s0 extensions, base64 encoded. .IP "\(bu" 2 The \s-1SCT\s0 signature, base64 encoded. .PP \&\fBSCT_set_source()\fR can be used to record where the \s-1SCT\s0 was found (\s-1TLS\s0 extension, X.509 certificate extension or \s-1OCSP\s0 response). This is not required for verifying the \s-1SCT.\s0 .SH "NOTES" .IX Header "NOTES" Some of the setters return int, instead of void. These will all return 1 on success, 0 on failure. They will not make changes on failure. .PP All of the setters will reset the validation status of the \s-1SCT\s0 to \&\s-1SCT_VALIDATION_STATUS_NOT_SET\s0 (see \fBSCT_validate\fR\|(3)). .PP \&\fBSCT_set_source()\fR will call \fBSCT_set_log_entry_type()\fR if the type of certificate the \s-1SCT\s0 was issued for can be inferred from where the \s-1SCT\s0 was found. For example, an \s-1SCT\s0 found in an X.509 extension must have been issued for a pre\- certificate. .PP \&\fBSCT_set_source()\fR will not refuse unknown values. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSCT_set_version()\fR returns 1 if the specified version is supported, 0 otherwise. .PP \&\fBSCT_set_log_entry_type()\fR returns 1 if the specified log entry type is supported, 0 otherwise. .PP \&\fBSCT_set0_log_id()\fR and \fBSCT_set1_log_id\fR return 1 if the specified LogID is a valid \s-1SHA\-256\s0 hash, 0 otherwise.

By modifying the method, alternative implementations such as hardware accelerators may be used. \s-1IMPORTANT:\s0 See the \s-1NOTES\s0 section for important information about how these \s-1DH API\s0 functions are affected by the use of \fB\s-1ENGINE\s0\fR \s-1API\s0 calls. .PP Initially, the default \s-1DH_METHOD\s0 is the OpenSSL internal implementation, as returned by \fBDH_OpenSSL()\fR. .PP \&\fBDH_set_default_method()\fR makes \fBmeth\fR the default method for all \s-1DH\s0 structures created later. \&\fB\s-1NB\s0\fR: This is true only whilst no \s-1ENGINE\s0 has been set as a default for \s-1DH,\s0 so this function is no longer recommended. This function is not thread-safe and should not be called at the same time as other OpenSSL functions. .PP \&\fBDH_get_default_method()\fR returns a pointer to the current default \s-1DH_METHOD.\s0 However, the meaningfulness of this result is dependent on whether the \s-1ENGINE API\s0 is being used, so this function is no longer recommended. .PP \&\fBDH_set_method()\fR selects \fBmeth\fR to perform all operations using the key \fBdh\fR. This will replace the \s-1DH_METHOD\s0 used by the \s-1DH\s0 key and if the previous method was supplied by an \s-1ENGINE,\s0 the handle to that \s-1ENGINE\s0 will be released during the change. It is possible to have \s-1DH\s0 keys that only work with certain \s-1DH_METHOD\s0 implementations (e.g. from an \s-1ENGINE\s0 module that supports embedded hardware-protected keys), and in such cases attempting to change the \s-1DH_METHOD\s0 for the key can have unexpected results. .PP \&\fBDH_new_method()\fR allocates and initializes a \s-1DH\s0 structure so that \fBengine\fR will be used for the \s-1DH\s0 operations. If \fBengine\fR is \s-1NULL,\s0 the default \s-1ENGINE\s0 for \s-1DH\s0 operations is used, and if no default \s-1ENGINE\s0 is set, the \s-1DH_METHOD\s0 controlled by \&\fBDH_set_default_method()\fR is used. .PP A new \s-1DH_METHOD\s0 object may be constructed using \fBDH_meth_new()\fR (see \&\fBDH_meth_new\fR\|(3)). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBDH_OpenSSL()\fR and \fBDH_get_default_method()\fR return pointers to the respective \&\fB\s-1DH_METHOD\s0\fRs. .PP \&\fBDH_set_default_method()\fR returns no value. .PP \&\fBDH_set_method()\fR returns nonzero if the provided \fBmeth\fR was successfully set as the method for \fBdh\fR (including unloading the \s-1ENGINE\s0 handle if the previous method was supplied by an \s-1ENGINE\s0). .PP \&\fBDH_new_method()\fR returns \s-1NULL\s0 and sets an error code that can be obtained by \&\fBERR_get_error\fR\|(3) if the allocation fails.

It provides a set of functions used by OpenSSL for the implementation of the various \s-1DSA\s0 capabilities. See the dsa page for more information. .PP \&\fBDSA_meth_new()\fR creates a new \fB\s-1DSA_METHOD\s0\fR structure. It should be given a unique \fBname\fR and a set of \fBflags\fR. The \fBname\fR should be a \s-1NULL\s0 terminated string, which will be duplicated and stored in the \fB\s-1DSA_METHOD\s0\fR object. It is the callers responsibility to free the original string. The flags will be used during the construction of a new \fB\s-1DSA\s0\fR object based on this \fB\s-1DSA_METHOD\s0\fR. Any new \fB\s-1DSA\s0\fR object will have those flags set by default. .PP \&\fBDSA_meth_dup()\fR creates a duplicate copy of the \fB\s-1DSA_METHOD\s0\fR object passed as a parameter. This might be useful for creating a new \fB\s-1DSA_METHOD\s0\fR based on an existing one, but with some differences. .PP \&\fBDSA_meth_free()\fR destroys a \fB\s-1DSA_METHOD\s0\fR structure and frees up any memory associated with it. .PP \&\fBDSA_meth_get0_name()\fR will return a pointer to the name of this \s-1DSA_METHOD.\s0 This is a pointer to the internal name string and so should not be freed by the caller. \fBDSA_meth_set1_name()\fR sets the name of the \s-1DSA_METHOD\s0 to \fBname\fR. The string is duplicated and the copy is stored in the \s-1DSA_METHOD\s0 structure, so the caller remains responsible for freeing the memory associated with the name. .PP \&\fBDSA_meth_get_flags()\fR returns the current value of the flags associated with this \&\s-1DSA_METHOD.\s0 \fBDSA_meth_set_flags()\fR provides the ability to set these flags. .PP The functions \fBDSA_meth_get0_app_data()\fR and \fBDSA_meth_set0_app_data()\fR provide the ability to associate implementation specific data with the \s-1DSA_METHOD.\s0 It is the application's responsibility to free this data before the \s-1DSA_METHOD\s0 is freed via a call to \fBDSA_meth_free()\fR. .PP \&\fBDSA_meth_get_sign()\fR and \fBDSA_meth_set_sign()\fR get and set the function used for creating a \s-1DSA\s0 signature respectively. This function will be called in response to the application calling \fBDSA_do_sign()\fR (or \fBDSA_sign()\fR). The parameters for the function have the same meaning as for \fBDSA_do_sign()\fR. .PP \&\fBDSA_meth_get_sign_setup()\fR and \fBDSA_meth_set_sign_setup()\fR get and set the function used for precalculating the \s-1DSA\s0 signature values \fBk^\-1\fR and \fBr\fR. This function will be called in response to the application calling \fBDSA_sign_setup()\fR. The parameters for the function have the same meaning as for \fBDSA_sign_setup()\fR. .PP \&\fBDSA_meth_get_verify()\fR and \fBDSA_meth_set_verify()\fR get and set the function used for verifying a \s-1DSA\s0 signature respectively. This function will be called in response to the application calling \fBDSA_do_verify()\fR (or \fBDSA_verify()\fR). The parameters for the function have the same meaning as for \fBDSA_do_verify()\fR. .PP \&\fBDSA_meth_get_mod_exp()\fR and \fBDSA_meth_set_mod_exp()\fR get and set the function used for computing the following value: .PP .Vb 1 \& rr = a1^p1 * a2^p2 mod m .Ve .PP This function will be called by the default OpenSSL method during verification of a \s-1DSA\s0 signature. The result is stored in the \fBrr\fR parameter. This function may be \s-1NULL.\s0 .PP \&\fBDSA_meth_get_bn_mod_exp()\fR and \fBDSA_meth_set_bn_mod_exp()\fR get and set the function used for computing the following value: .PP .Vb 1 \& r = a ^ p mod m .Ve .PP This function will be called by the default OpenSSL function for \&\fBDSA_sign_setup()\fR. The result is stored in the \fBr\fR parameter. This function may be \s-1NULL.\s0 .PP \&\fBDSA_meth_get_init()\fR and \fBDSA_meth_set_init()\fR get and set the function used for creating a new \s-1DSA\s0 instance respectively. This function will be called in response to the application calling \fBDSA_new()\fR (if the current default \&\s-1DSA_METHOD\s0 is this one) or \fBDSA_new_method()\fR. The \fBDSA_new()\fR and \fBDSA_new_method()\fR functions will allocate the memory for the new \s-1DSA\s0 object, and a pointer to this newly allocated structure will be passed as a parameter to the function. This function may be \s-1NULL.\s0 .PP \&\fBDSA_meth_get_finish()\fR and \fBDSA_meth_set_finish()\fR get and set the function used for destroying an instance of a \s-1DSA\s0 object respectively. This function will be called in response to the application calling \fBDSA_free()\fR. A pointer to the \s-1DSA\s0 to be destroyed is passed as a parameter. The destroy function should be used for \s-1DSA\s0 implementation specific clean up. The memory for the \s-1DSA\s0 itself should not be freed by this function. This function may be \s-1NULL.\s0 .PP \&\fBDSA_meth_get_paramgen()\fR and \fBDSA_meth_set_paramgen()\fR get and set the function used for generating \s-1DSA\s0 parameters respectively. This function will be called in response to the application calling \fBDSA_generate_parameters_ex()\fR (or \&\fBDSA_generate_parameters()\fR).

These functions are: .IP "an opener" 4 .IX Item "an opener" This function takes a reference to a \s-1UI\s0 and starts a session, for example by opening a channel to a tty, or by creating a dialog box. .IP "a writer" 4 .IX Item "a writer" This function takes a reference to a \s-1UI\s0 and a \s-1UI\s0 String, and writes the string where appropriate, maybe to the tty, maybe added as a field label in a dialog box. Note that this gets fed all strings associated with a \s-1UI,\s0 one after the other, so care must be taken which ones it actually uses. .IP "a flusher" 4 .IX Item "a flusher" This function takes a reference to a \s-1UI,\s0 and flushes everything that has been output so far. For example, if the method builds up a dialog box, this can be used to actually display it and accepting input ended with a pressed button. .IP "a reader" 4 .IX Item "a reader" This function takes a reference to a \s-1UI\s0 and a \s-1UI\s0 string and reads off the given prompt, maybe from the tty, maybe from a field in a dialog box. Note that this gets fed all strings associated with a \s-1UI,\s0 one after the other, so care must be taken which ones it actually uses. .IP "a closer" 4 .IX Item "a closer" This function takes a reference to a \s-1UI,\s0 and closes the session, maybe by closing the channel to the tty, maybe by destroying a dialog box. .PP All of these functions are expected to return 0 on error, 1 on success, or \-1 on out-off-band events, for example if some prompting has been cancelled (by pressing Ctrl-C, for example). Only the flusher or the reader are expected to return \-1. If returned by another of the functions, it's treated as if 0 was returned. .PP Regarding the writer and the reader, don't assume the former should only write and don't assume the latter should only read. This depends on the needs of the method. .PP For example, a typical tty reader wouldn't write the prompts in the write, but would rather do so in the reader, because of the sequential nature of prompting on a tty. This is how the \fBUI_OpenSSL()\fR method does it. .PP In contrast, a method that builds up a dialog box would add all prompt text in the writer, have all input read in the flusher and store the results in some temporary buffer, and finally have the reader just fetch those results. .PP The central function that uses these method functions is \fBUI_process()\fR, and it does it in five steps: .IP "1." 4 Open the session using the opener function if that one's defined. If an error occurs, jump to 5. .IP "2." 4 For every \s-1UI\s0 String associated with the \s-1UI,\s0 call the writer function if that one's defined. If an error occurs, jump to 5. .IP "3." 4 Flush everything using the flusher function if that one's defined. If an error occurs, jump to 5. .IP "4." 4 For every \s-1UI\s0 String associated with the \s-1UI,\s0 call the reader function if that one's defined. If an error occurs, jump to 5. .IP "5." 4 Close the session using the closer function if that one's defined. .PP \&\fBUI_create_method()\fR creates a new \s-1UI\s0 method with a given \fBname\fR. .PP \&\fBUI_destroy_method()\fR destroys the given \s-1UI\s0 method \fBui_method\fR. .PP \&\fBUI_method_set_opener()\fR, \fBUI_method_set_writer()\fR, \&\fBUI_method_set_flusher()\fR, \fBUI_method_set_reader()\fR and \&\fBUI_method_set_closer()\fR set the five main method function to the given function pointer. .PP \&\fBUI_method_set_data_duplicator()\fR sets the user data duplicator and destructor. See \fBUI_dup_user_data\fR\|(3). .PP \&\fBUI_method_set_prompt_constructor()\fR sets the prompt constructor.

This lifetime is specified by storing the creation time of the session and the timeout value valid at this time. If the actual time is later than creation time plus timeout, the session is not reused. .PP Due to this realization, all sessions behave according to the timeout value valid at the time of the session negotiation. Changes of the timeout value do not affect already established sessions. .PP The expiration time of a single session can be modified using the \&\fBSSL_SESSION_get_time\fR\|(3) family of functions. .PP Expired sessions are removed from the internal session cache, whenever \&\fBSSL_CTX_flush_sessions\fR\|(3) is called, either directly by the application or automatically (see \&\fBSSL_CTX_set_session_cache_mode\fR\|(3)) .PP The default value for session timeout is decided on a per protocol basis, see \fBSSL_get_default_timeout\fR\|(3). All currently supported protocols have the same default timeout value of 300 seconds. .PP This timeout value is used as the ticket lifetime hint for stateless session tickets. It is also used as the timeout value within the ticket itself. .PP For TLSv1.3, \s-1RFC8446\s0 limits transmission of this value to 1 week (604800 seconds). .PP For TLSv1.2, tickets generated during an initial handshake use the value as specified.

Specifying 0 indicates that any type can be used. \fBprotocol\fR specifies a protocol such as \&\s-1IPPROTO_TCP, IPPROTO_UDP\s0 or \s-1IPPORTO_SCTP.\s0 If set to 0 than any protocol can be used. \fBres\fR points at a pointer to hold the start of a \fB\s-1BIO_ADDRINFO\s0\fR chain. .PP For the family \fB\s-1AF_UNIX\s0\fR, \fBBIO_lookup_ex()\fR will ignore the \fBservice\fR parameter and expects the \fBnode\fR parameter to hold the path to the socket file. .PP \&\fBBIO_lookup()\fR does the same as \fBBIO_lookup_ex()\fR but does not provide the ability to select based on the protocol (any protocol may be returned). .PP \&\fBBIO_ADDRINFO_family()\fR returns the family of the given \&\fB\s-1BIO_ADDRINFO\s0\fR. The result will be one of the constants \&\s-1AF_INET, AF_INET6\s0 and \s-1AF_UNIX.\s0 .PP \&\fBBIO_ADDRINFO_socktype()\fR returns the socket type of the given \&\fB\s-1BIO_ADDRINFO\s0\fR. The result will be one of the constants \&\s-1SOCK_STREAM\s0 and \s-1SOCK_DGRAM.\s0 .PP \&\fBBIO_ADDRINFO_protocol()\fR returns the protocol id of the given \&\fB\s-1BIO_ADDRINFO\s0\fR. The result will be one of the constants \&\s-1IPPROTO_TCP\s0 and \s-1IPPROTO_UDP.\s0 .PP \&\fBBIO_ADDRINFO_address()\fR returns the underlying \fB\s-1BIO_ADDR\s0\fR of the given \fB\s-1BIO_ADDRINFO\s0\fR. .PP \&\fBBIO_ADDRINFO_next()\fR returns the next \fB\s-1BIO_ADDRINFO\s0\fR in the chain from the given one. .PP \&\fBBIO_ADDRINFO_free()\fR frees the chain of \fB\s-1BIO_ADDRINFO\s0\fR starting with the given one. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_lookup_ex()\fR and \fBBIO_lookup()\fR return 1 on success and 0 when an error occurred, and will leave an error indication on the OpenSSL error stack in that case. .PP All other functions described here return 0 or \fB\s-1NULL\s0\fR when the information they should return isn't available. .SH "NOTES" .IX Header "NOTES" The \fBBIO_lookup_ex()\fR implementation uses the platform provided \fBgetaddrinfo()\fR function. On Linux it is known that specifying 0 for the protocol will not return any \s-1SCTP\s0 based addresses when calling \fBgetaddrinfo()\fR. Therefore, if an \s-1SCTP\s0 address is required then the \fBprotocol\fR parameter to \fBBIO_lookup_ex()\fR should be explicitly set to \s-1IPPROTO_SCTP.\s0 The same may be true on other platforms. .SH "HISTORY" .IX Header "HISTORY" The \fBBIO_lookup_ex()\fR function was added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2020 The OpenSSL Project Authors.

In this sense \s-1PEM\s0 format is simply base64 encoded data surrounded by header lines. .PP For more details about the meaning of arguments see the \&\fB\s-1PEM FUNCTION ARGUMENTS\s0\fR section. .PP Each operation has four functions associated with it. For brevity the term "\fB\s-1TYPE\s0\fR functions" will be used below to collectively refer to the \fBPEM_read_bio_TYPE()\fR, \fBPEM_read_TYPE()\fR, \&\fBPEM_write_bio_TYPE()\fR, and \fBPEM_write_TYPE()\fR functions. .PP The \fBPrivateKey\fR functions read or write a private key in \s-1PEM\s0 format using an \&\s-1EVP_PKEY\s0 structure. The write routines use PKCS#8 private key format and are equivalent to \fBPEM_write_bio_PKCS8PrivateKey()\fR.The read functions transparently handle traditional and PKCS#8 format encrypted and unencrypted keys. .PP \&\fBPEM_write_bio_PrivateKey_traditional()\fR writes out a private key in the \&\*(L"traditional\*(R" format with a simple private key marker and should only be used for compatibility with legacy programs. .PP \&\fBPEM_write_bio_PKCS8PrivateKey()\fR and \fBPEM_write_PKCS8PrivateKey()\fR write a private key in an \s-1EVP_PKEY\s0 structure in PKCS#8 EncryptedPrivateKeyInfo format using PKCS#5 v2.0 password based encryption algorithms. The \fBcipher\fR argument specifies the encryption algorithm to use: unlike some other \s-1PEM\s0 routines the encryption is applied at the PKCS#8 level and not in the \s-1PEM\s0 headers. If \&\fBcipher\fR is \s-1NULL\s0 then no encryption is used and a PKCS#8 PrivateKeyInfo structure is used instead. .PP \&\fBPEM_write_bio_PKCS8PrivateKey_nid()\fR and \fBPEM_write_PKCS8PrivateKey_nid()\fR also write out a private key as a PKCS#8 EncryptedPrivateKeyInfo however it uses PKCS#5 v1.5 or PKCS#12 encryption algorithms instead. The algorithm to use is specified in the \fBnid\fR parameter and should be the \s-1NID\s0 of the corresponding \s-1OBJECT IDENTIFIER\s0 (see \s-1NOTES\s0 section). .PP The \fB\s-1PUBKEY\s0\fR functions process a public key using an \s-1EVP_PKEY\s0 structure. The public key is encoded as a SubjectPublicKeyInfo structure. .PP The \fBRSAPrivateKey\fR functions process an \s-1RSA\s0 private key using an \&\s-1RSA\s0 structure. The write routines uses traditional format. The read routines handles the same formats as the \fBPrivateKey\fR functions but an error occurs if the private key is not \s-1RSA.\s0 .PP The \fBRSAPublicKey\fR functions process an \s-1RSA\s0 public key using an \&\s-1RSA\s0 structure. The public key is encoded using a PKCS#1 RSAPublicKey structure. .PP The \fB\s-1RSA_PUBKEY\s0\fR functions also process an \s-1RSA\s0 public key using an \s-1RSA\s0 structure. However, the public key is encoded using a SubjectPublicKeyInfo structure and an error occurs if the public key is not \s-1RSA.\s0 .PP The \fBDSAPrivateKey\fR functions process a \s-1DSA\s0 private key using a \&\s-1DSA\s0 structure. The write routines uses traditional format. The read routines handles the same formats as the \fBPrivateKey\fR functions but an error occurs if the private key is not \s-1DSA.\s0 .PP The \fB\s-1DSA_PUBKEY\s0\fR functions process a \s-1DSA\s0 public key using a \s-1DSA\s0 structure. The public key is encoded using a SubjectPublicKeyInfo structure and an error occurs if the public key is not \s-1DSA.\s0 .PP The \fBParameters\fR functions read or write key parameters in \s-1PEM\s0 format using an \s-1EVP_PKEY\s0 structure. The encoding depends on the type of key; for \s-1DSA\s0 key parameters, it will be a Dss-Parms structure as defined in \s-1RFC2459,\s0 and for \s-1DH\s0 key parameters, it will be a PKCS#3 DHparameter structure. \fIThese functions only exist for the \f(BI\s-1BIO\s0\fI type\fR. .PP The \fBDSAparams\fR functions process \s-1DSA\s0 parameters using a \s-1DSA\s0 structure. The parameters are encoded using a Dss-Parms structure as defined in \s-1RFC2459.\s0 .PP The \fBDHparams\fR functions process \s-1DH\s0 parameters using a \s-1DH\s0 structure. The parameters are encoded using a PKCS#3 DHparameter structure. .PP The \fBX509\fR functions process an X509 certificate using an X509 structure. They will also process a trusted X509 certificate but any trust settings are discarded. .PP The \fBX509_AUX\fR functions process a trusted X509 certificate using an X509 structure. .PP The \fBX509_REQ\fR and \fBX509_REQ_NEW\fR functions process a PKCS#10 certificate request using an X509_REQ structure. The \fBX509_REQ\fR write functions use \fB\s-1CERTIFICATE REQUEST\s0\fR in the header whereas the \fBX509_REQ_NEW\fR functions use \fB\s-1NEW CERTIFICATE REQUEST\s0\fR (as required by some CAs). The \fBX509_REQ\fR read functions will handle either form so there are no \fBX509_REQ_NEW\fR read functions. .PP The \fBX509_CRL\fR functions process an X509 \s-1CRL\s0 using an X509_CRL structure. .PP The \fB\s-1PKCS7\s0\fR functions process a PKCS#7 ContentInfo using a \s-1PKCS7\s0 structure. .SH "PEM FUNCTION ARGUMENTS" .IX Header "PEM FUNCTION ARGUMENTS" The \s-1PEM\s0 functions have many common arguments. .PP The \fBbp\fR \s-1BIO\s0 parameter (if present) specifies the \s-1BIO\s0 to read from or write to. .PP The \fBfp\fR \s-1FILE\s0 parameter (if present) specifies the \s-1FILE\s0 pointer to read from or write to. .PP The \s-1PEM\s0 read functions all take an argument \fB\s-1TYPE\s0 **x\fR and return a \fB\s-1TYPE\s0 *\fR pointer. Where \fB\s-1TYPE\s0\fR is whatever structure the function uses. If \fBx\fR is \s-1NULL\s0 then the parameter is ignored. If \fBx\fR is not \&\s-1NULL\s0 but \fB*x\fR is \s-1NULL\s0 then the structure returned will be written to \fB*x\fR. If neither \fBx\fR nor \fB*x\fR is \s-1NULL\s0 then an attempt is made to reuse the structure at \fB*x\fR (but see \s-1BUGS\s0 and \s-1EXAMPLES\s0 sections). Irrespective of the value of \fBx\fR a pointer to the structure is always returned (or \s-1NULL\s0 if an error occurred). .PP The \s-1PEM\s0 functions which write private keys take an \fBenc\fR parameter which specifies the encryption algorithm to use, encryption is done at the \s-1PEM\s0 level. If this parameter is set to \s-1NULL\s0 then the private key is written in unencrypted form. .PP The \fBcb\fR argument is the callback to use when querying for the pass phrase used for encrypted \s-1PEM\s0 structures (normally only private keys). .PP For the \s-1PEM\s0 write routines if the \fBkstr\fR parameter is not \s-1NULL\s0 then \&\fBklen\fR bytes at \fBkstr\fR are used as the passphrase and \fBcb\fR is ignored. .PP If the \fBcb\fR parameters is set to \s-1NULL\s0 and the \fBu\fR parameter is not \&\s-1NULL\s0 then the \fBu\fR parameter is interpreted as a null terminated string to use as the passphrase. If both \fBcb\fR and \fBu\fR are \s-1NULL\s0 then the default callback routine is used which will typically prompt for the passphrase on the current terminal with echoing turned off. .PP The default passphrase callback is sometimes inappropriate (for example in a \s-1GUI\s0 application) so an alternative can be supplied. The callback routine has the following form: .PP .Vb 1 \& int cb(char *buf, int size, int rwflag, void *u); .Ve .PP \&\fBbuf\fR is the buffer to write the passphrase to. \fBsize\fR is the maximum length of the passphrase (i.e. the size of buf). \fBrwflag\fR is a flag which is set to 0 when reading and 1 when writing. A typical routine will ask the user to verify the passphrase (for example by prompting for it twice) if \fBrwflag\fR is 1. The \fBu\fR parameter has the same value as the \fBu\fR parameter passed to the \s-1PEM\s0 routine. It allows arbitrary data to be passed to the callback by the application (for example a window handle in a \s-1GUI\s0 application). The callback \&\fBmust\fR return the number of characters in the passphrase or \-1 if an error occurred. .SH "NOTES" .IX Header "NOTES" The old \fBPrivateKey\fR write routines are retained for compatibility. New applications should write private keys using the \&\fBPEM_write_bio_PKCS8PrivateKey()\fR or \fBPEM_write_PKCS8PrivateKey()\fR routines because they are more secure (they use an iteration count of 2048 whereas the traditional routines use a count of 1) unless compatibility with older versions of OpenSSL is important. .PP The \fBPrivateKey\fR read routines can be used in all applications because they handle all formats transparently. .PP A frequent cause of problems is attempting to use the \s-1PEM\s0 routines like this: .PP .Vb 1 \& X509 *x; \& \& PEM_read_bio_X509(bp, &x, 0, NULL); .Ve .PP this is a bug because an attempt will be made to reuse the data at \fBx\fR which is an uninitialised pointer. .PP These functions make no assumption regarding the pass phrase received from the password callback. It will simply be treated as a byte sequence. .SH "PEM ENCRYPTION FORMAT" .IX Header "PEM ENCRYPTION FORMAT" These old \fBPrivateKey\fR routines use a non standard technique for encryption. .PP The private key (or other data) takes the following form: .PP .Vb 3 \& \-\-\-\-\-BEGIN RSA PRIVATE KEY\-\-\-\-\- \& Proc\-Type: 4,ENCRYPTED \& DEK\-Info: DES\-EDE3\-CBC,3F17F5316E2BAC89 \& \& ...base64 encoded data... \& \-\-\-\-\-END RSA PRIVATE KEY\-\-\-\-\- .Ve .PP The line beginning with \fIProc-Type\fR contains the version and the protection on the encapsulated data. The line beginning \fIDEK-Info\fR contains two comma separated values: the encryption algorithm name as used by \fBEVP_get_cipherbyname()\fR and an initialization vector used by the cipher encoded as a set of hexadecimal digits. After those two lines is the base64\-encoded encrypted data. .PP The encryption key is derived using \fBEVP_BytesToKey()\fR. The cipher's initialization vector is passed to \fBEVP_BytesToKey()\fR as the \fBsalt\fR parameter. Internally, \fB\s-1PKCS5_SALT_LEN\s0\fR bytes of the salt are used (regardless of the size of the initialization vector). The user's password is passed to \fBEVP_BytesToKey()\fR using the \fBdata\fR and \fBdatal\fR parameters. Finally, the library uses an iteration count of 1 for \&\fBEVP_BytesToKey()\fR. .PP The \fBkey\fR derived by \fBEVP_BytesToKey()\fR along with the original initialization vector is then used to decrypt the encrypted data. The \fBiv\fR produced by \&\fBEVP_BytesToKey()\fR is not utilized or needed, and \s-1NULL\s0 should be passed to the function. .PP The pseudo code to derive the key would look similar to: .PP .Vb 2 \& EVP_CIPHER* cipher = EVP_des_ede3_cbc(); \& EVP_MD* md = EVP_md5(); \& \& unsigned int nkey = EVP_CIPHER_key_length(cipher); \& unsigned int niv = EVP_CIPHER_iv_length(cipher); \& unsigned char key[nkey]; \& unsigned char iv[niv]; \& \& memcpy(iv, HexToBin("3F17F5316E2BAC89"), niv); \& rc = EVP_BytesToKey(cipher, md, iv /*salt*/, pword, plen, 1, key, NULL /*iv*/); \& if (rc != nkey) \& /* Error */ \& \& /* On success, use key and iv to initialize the cipher */ .Ve .SH "BUGS" .IX Header "BUGS" The \s-1PEM\s0 read routines in some versions of OpenSSL will not correctly reuse an existing structure. Therefore, the following: .PP .Vb 1 \& PEM_read_bio_X509(bp, &x, 0, NULL); .Ve .PP where \fBx\fR already contains a valid certificate, may not work, whereas: .PP .Vb 2 \& X509_free(x); \& x = PEM_read_bio_X509(bp, NULL, 0, NULL); .Ve .PP is guaranteed to work. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The read routines return either a pointer to the structure read or \s-1NULL\s0 if an error occurred. .PP The write routines return 1 for success or 0 for failure. .SH "EXAMPLES" .IX Header "EXAMPLES" Although the \s-1PEM\s0 routines take several arguments in almost all applications most of them are set to 0 or \s-1NULL.\s0 .PP Read a certificate in \s-1PEM\s0 format from a \s-1BIO:\s0 .PP .Vb 1 \& X509 *x; \& \& x = PEM_read_bio_X509(bp, NULL, 0, NULL); \& if (x == NULL) \& /* Error */ .Ve .PP Alternative method: .PP .Vb 1 \& X509 *x = NULL; \& \& if (!PEM_read_bio_X509(bp, &x, 0, NULL)) \& /* Error */ .Ve .PP Write a certificate to a \s-1BIO:\s0 .PP .Vb 2 \& if (!PEM_write_bio_X509(bp, x)) \& /* Error */ .Ve .PP Write a private key (using traditional format) to a \s-1BIO\s0 using triple \s-1DES\s0 encryption, the pass phrase is prompted for: .PP .Vb 2 \& if (!PEM_write_bio_PrivateKey(bp, key, EVP_des_ede3_cbc(), NULL, 0, 0, NULL)) \& /* Error */ .Ve .PP Write a private key (using PKCS#8 format) to a \s-1BIO\s0 using triple \&\s-1DES\s0 encryption, using the pass phrase \*(L"hello\*(R": .PP .Vb 3 \& if (!PEM_write_bio_PKCS8PrivateKey(bp, key, EVP_des_ede3_cbc(), \& NULL, 0, 0, "hello")) \& /* Error */ .Ve .PP Read a private key from a \s-1BIO\s0 using a pass phrase callback: .PP .Vb 3 \& key = PEM_read_bio_PrivateKey(bp, NULL, pass_cb, "My Private Key"); \& if (key == NULL) \& /* Error */ .Ve .PP Skeleton pass phrase callback: .PP .Vb 2 \& int pass_cb(char *buf, int size, int rwflag, void *u) \& { \& \& /* We\*(Aqd probably do something else if \*(Aqrwflag\*(Aq is 1 */ \& printf("Enter pass phrase for \e"%s\e"\en", (char *)u); \& \& /* get pass phrase, length \*(Aqlen\*(Aq into \*(Aqtmp\*(Aq */ \& char *tmp = "hello"; \& if (tmp == NULL) /* An error occurred */ \& return \-1; \& \& size_t len = strlen(tmp); \& \& if (len > size) \& len = size; \& memcpy(buf, tmp, len); \& return len; \& } .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_EncryptInit\fR\|(3), \fBEVP_BytesToKey\fR\|(3), \&\fBpassphrase\-encoding\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" The old Netscape certificate sequences were no longer documented in OpenSSL 1.1.0; applications should use the \s-1PKCS7\s0 standard instead as they will be formally deprecated in a future releases. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2020 The OpenSSL Project Authors.

The subroutines in question instrument these references for purposes of gathering randomness for random number generator. In order to make it bus-bound a 'flush cache line' instruction is used between probes. In addition probes are added to \fBvector\fR elements in atomic or interlocked manner, which should contribute additional noise on multi-processor systems. This also means that \fBvector[num]\fR should be zeroed upon invocation (if you want to retrieve actual probe values). .PP \&\fBOPENSSL_instrument_bus()\fR performs \fBnum\fR probes and records the number of oscillator cycles every probe took. .PP \&\fBOPENSSL_instrument_bus2()\fR on the other hand \fBaccumulates\fR consecutive probes with the same value, i.e. in a way it records duration of periods when probe values appeared deterministic. The subroutine performs at most \fBmax\fR probes in attempt to fill the \fBvector[num]\fR, with \fBmax\fR value of 0 meaning \*(L"as many as it takes.\*(R" .SH "RETURN VALUES" .IX Header "RETURN VALUES" Return value of 0 indicates that \s-1CPU\s0 is not capable of performing the benchmark, either because oscillator counter or 'flush cache line' is not available on current platform. For reference, on x86 'flush cache line' was introduced with the \s-1SSE2\s0 extensions. .PP Otherwise number of recorded values is returned. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2011\-2018 The OpenSSL Project Authors.

In addition, \fB\s-1CRYPTO_EX_INDEX_APP\s0\fR is reserved for applications to use this facility for their own structures. .PP The \s-1API\s0 described here is used by OpenSSL to manipulate exdata for specific structures. Since the application data can be anything at all it is passed and retrieved as a \fBvoid *\fR type. .PP The \fB\s-1CRYPTO_EX_DATA\s0\fR type is opaque. To initialize the exdata part of a structure, call \fBCRYPTO_new_ex_data()\fR. This is only necessary for \&\fB\s-1CRYPTO_EX_INDEX_APP\s0\fR objects. .PP Exdata types are identified by an \fBindex\fR, an integer guaranteed to be unique within structures for the lifetime of the program. Applications using exdata typically call \fBCRYPTO_get_ex_new_index\fR at startup, and store the result in a global variable, or write a wrapper function to provide lazy evaluation. The \fBclass_index\fR should be one of the \&\fBCRYPTO_EX_INDEX_xxx\fR values. The \fBargl\fR and \fBargp\fR parameters are saved to be passed to the callbacks but are otherwise not used. In order to transparently manipulate exdata, three callbacks must be provided. The semantics of those callbacks are described below. .PP When copying or releasing objects with exdata, the callback functions are called in increasing order of their \fBindex\fR value. .PP If a dynamic library can be unloaded, it should call \fBCRYPTO_free_ex_index()\fR when this is done. This will replace the callbacks with no-ops so that applications don't crash. Any existing exdata will be leaked. .PP To set or get the exdata on an object, the appropriate type-specific routine must be used. This is because the containing structure is opaque and the \fB\s-1CRYPTO_EX_DATA\s0\fR field is not accessible. In both \s-1API\s0's, the \&\fBidx\fR parameter should be an already-created index value. .PP When setting exdata, the pointer specified with a particular index is saved, and returned on a subsequent \*(L"get\*(R" call. If the application is going to release the data, it must make sure to set a \fB\s-1NULL\s0\fR value at the index, to avoid likely double-free crashes. .PP The function \fBCRYPTO_free_ex_data\fR is used to free all exdata attached to a structure. The appropriate type-specific routine must be used. The \fBclass_index\fR identifies the structure type, the \fBobj\fR is a pointer to the actual structure, and \fBr\fR is a pointer to the structure's exdata field. .SS "Callback Functions" .IX Subsection "Callback Functions" This section describes how the callback functions are used. Applications that are defining their own exdata using \fB\s-1CYPRTO_EX_INDEX_APP\s0\fR must call them as described here. .PP When a structure is initially allocated (such as \fBRSA_new()\fR) then the \&\fBnew_func()\fR is called for every defined index. There is no requirement that the entire parent, or containing, structure has been set up. The \fBnew_func()\fR is typically used only to allocate memory to store the exdata, and perhaps an \*(L"initialized\*(R" flag within that memory. The exdata value should be set by calling \fBCRYPTO_set_ex_data()\fR. .PP When a structure is free'd (such as \fBSSL_CTX_free()\fR) then the \&\fBfree_func()\fR is called for every defined index. Again, the state of the parent structure is not guaranteed. The \fBfree_func()\fR may be called with a \&\s-1NULL\s0 pointer. .PP Both \fBnew_func()\fR and \fBfree_func()\fR take the same parameters. The \fBparent\fR is the pointer to the structure that contains the exdata. The \fBptr\fR is the current exdata item; for \fBnew_func()\fR this will typically be \s-1NULL.\s0 The \fBr\fR parameter is a pointer to the exdata field of the object. The \fBidx\fR is the index and is the value returned when the callbacks were initially registered via \fBCRYPTO_get_ex_new_index()\fR and can be used if the same callback handles different types of exdata. .PP \&\fBdup_func()\fR is called when a structure is being copied. This is only done for \fB\s-1SSL\s0\fR, \fB\s-1SSL_SESSION\s0\fR, \fB\s-1EC_KEY\s0\fR objects and \fB\s-1BIO\s0\fR chains via \&\fBBIO_dup_chain()\fR. The \fBto\fR and \fBfrom\fR parameters are pointers to the destination and source \fB\s-1CRYPTO_EX_DATA\s0\fR structures, respectively. The \fBfrom_d\fR parameter needs to be cast to a \fBvoid **pptr\fR as the \s-1API\s0 has currently the wrong signature; that will be changed in a future version. The \fB*pptr\fR is a pointer to the source exdata. When the \fBdup_func()\fR returns, the value in \fB*pptr\fR is copied to the destination ex_data. If the pointer contained in \fB*pptr\fR is not modified by the \fBdup_func()\fR, then both \fBto\fR and \fBfrom\fR will point to the same data. The \fBidx\fR, \fBargl\fR and \fBargp\fR parameters are as described for the other two callbacks. If the \fBdup_func()\fR returns \fB0\fR the whole \fBCRYPTO_dup_ex_data()\fR will fail. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBCRYPTO_get_ex_new_index()\fR returns a new index or \-1 on failure. .PP \&\fBCRYPTO_free_ex_index()\fR and \&\fBCRYPTO_set_ex_data()\fR return 1 on success or 0 on failure. .PP \&\fBCRYPTO_get_ex_data()\fR returns the application data or \s-1NULL\s0 on failure; note that \s-1NULL\s0 may be a valid value. .PP \&\fBdup_func()\fR should return 0 for failure and 1 for success. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2015\-2019 The OpenSSL Project Authors.

These macros define typesafe inline functions that wrap around the utility \fBOPENSSL_sk_\fR \s-1API.\s0 In the description here, \fI\s-1TYPE\s0\fR is used as a placeholder for any of the OpenSSL datatypes, such as \fIX509\fR. .PP \&\s-1\fBSTACK_OF\s0()\fR returns the name for a stack of the specified \fB\s-1TYPE\s0\fR. \&\s-1\fBDEFINE_STACK_OF\s0()\fR creates set of functions for a stack of \fB\s-1TYPE\s0\fR. This will mean that type \fB\s-1TYPE\s0\fR is stored in each stack, the type is referenced by \&\s-1STACK_OF\s0(\s-1TYPE\s0) and each function name begins with \fIsk_TYPE_\fR. For example: .PP .Vb 1 \& TYPE *sk_TYPE_value(STACK_OF(TYPE) *sk, int idx); .Ve .PP \&\s-1\fBDEFINE_STACK_OF_CONST\s0()\fR is identical to \s-1\fBDEFINE_STACK_OF\s0()\fR except each element is constant. For example: .PP .Vb 1 \& const TYPE *sk_TYPE_value(STACK_OF(TYPE) *sk, int idx); .Ve .PP \&\s-1\fBDEFINE_SPECIAL_STACK_OF\s0()\fR defines a stack of \fB\s-1TYPE\s0\fR but each function uses \fB\s-1FUNCNAME\s0\fR in the function name. For example: .PP .Vb 1 \& TYPE *sk_FUNCNAME_value(STACK_OF(TYPE) *sk, int idx); .Ve .PP \&\s-1\fBDEFINE_SPECIAL_STACK_OF_CONST\s0()\fR is similar except that each element is constant: .PP .Vb 1 \& const TYPE *sk_FUNCNAME_value(STACK_OF(TYPE) *sk, int idx); .Ve .PP \&\fBsk_TYPE_num()\fR returns the number of elements in \fBsk\fR or \-1 if \fBsk\fR is \&\fB\s-1NULL\s0\fR. .PP \&\fBsk_TYPE_value()\fR returns element \fBidx\fR in \fBsk\fR, where \fBidx\fR starts at zero. If \fBidx\fR is out of range then \fB\s-1NULL\s0\fR is returned. .PP \&\fBsk_TYPE_new()\fR allocates a new empty stack using comparison function \fBcompare\fR. If \fBcompare\fR is \fB\s-1NULL\s0\fR then no comparison function is used. This function is equivalent to sk_TYPE_new_reserve(compare, 0). .PP \&\fBsk_TYPE_new_null()\fR allocates a new empty stack with no comparison function. This function is equivalent to sk_TYPE_new_reserve(\s-1NULL, 0\s0). .PP \&\fBsk_TYPE_reserve()\fR allocates additional memory in the \fBsk\fR structure such that the next \fBn\fR calls to \fBsk_TYPE_insert()\fR, \fBsk_TYPE_push()\fR or \fBsk_TYPE_unshift()\fR will not fail or cause memory to be allocated or reallocated. If \fBn\fR is zero, any excess space allocated in the \&\fBsk\fR structure is freed. On error \fBsk\fR is unchanged. .PP \&\fBsk_TYPE_new_reserve()\fR allocates a new stack. The new stack will have additional memory allocated to hold \fBn\fR elements if \fBn\fR is positive. The next \fBn\fR calls to \fBsk_TYPE_insert()\fR, \fBsk_TYPE_push()\fR or \fBsk_TYPE_unshift()\fR will not fail or cause memory to be allocated or reallocated. If \fBn\fR is zero or less than zero, no memory is allocated. \fBsk_TYPE_new_reserve()\fR also sets the comparison function \&\fBcompare\fR to the newly created stack. If \fBcompare\fR is \fB\s-1NULL\s0\fR then no comparison function is used. .PP \&\fBsk_TYPE_set_cmp_func()\fR sets the comparison function of \fBsk\fR to \fBcompare\fR. The previous comparison function is returned or \fB\s-1NULL\s0\fR if there was no previous comparison function. .PP \&\fBsk_TYPE_free()\fR frees up the \fBsk\fR structure. It does \fBnot\fR free up any elements of \fBsk\fR. After this call \fBsk\fR is no longer valid. .PP \&\fBsk_TYPE_zero()\fR sets the number of elements in \fBsk\fR to zero. It does not free \&\fBsk\fR so after this call \fBsk\fR is still valid. .PP \&\fBsk_TYPE_pop_free()\fR frees up all elements of \fBsk\fR and \fBsk\fR itself. The free function \fBfreefunc()\fR is called on each element to free it. .PP \&\fBsk_TYPE_delete()\fR deletes element \fBi\fR from \fBsk\fR. It returns the deleted element or \fB\s-1NULL\s0\fR if \fBi\fR is out of range. .PP \&\fBsk_TYPE_delete_ptr()\fR deletes element matching \fBptr\fR from \fBsk\fR. It returns the deleted element or \fB\s-1NULL\s0\fR if no element matching \fBptr\fR was found. .PP \&\fBsk_TYPE_insert()\fR inserts \fBptr\fR into \fBsk\fR at position \fBidx\fR. Any existing elements at or after \fBidx\fR are moved downwards. If \fBidx\fR is out of range the new element is appended to \fBsk\fR. \fBsk_TYPE_insert()\fR either returns the number of elements in \fBsk\fR after the new element is inserted or zero if an error (such as memory allocation failure) occurred. .PP \&\fBsk_TYPE_push()\fR appends \fBptr\fR to \fBsk\fR it is equivalent to: .PP .Vb 1 \& sk_TYPE_insert(sk, ptr, \-1); .Ve .PP \&\fBsk_TYPE_unshift()\fR inserts \fBptr\fR at the start of \fBsk\fR it is equivalent to: .PP .Vb 1 \& sk_TYPE_insert(sk, ptr, 0); .Ve .PP \&\fBsk_TYPE_pop()\fR returns and removes the last element from \fBsk\fR. .PP \&\fBsk_TYPE_shift()\fR returns and removes the first element from \fBsk\fR. .PP \&\fBsk_TYPE_set()\fR sets element \fBidx\fR of \fBsk\fR to \fBptr\fR replacing the current element. The new element value is returned or \fB\s-1NULL\s0\fR if an error occurred: this will only happen if \fBsk\fR is \fB\s-1NULL\s0\fR or \fBidx\fR is out of range. .PP \&\fBsk_TYPE_find()\fR searches \fBsk\fR for the element \fBptr\fR. In the case where no comparison function has been specified, the function performs a linear search for a pointer equal to \fBptr\fR. The index of the first matching element is returned or \fB\-1\fR if there is no match. In the case where a comparison function has been specified, \fBsk\fR is sorted then \&\fBsk_TYPE_find()\fR returns the index of a matching element or \fB\-1\fR if there is no match. Note that, in this case, the matching element returned is not guaranteed to be the first; the comparison function will usually compare the values pointed to rather than the pointers themselves and the order of elements in \fBsk\fR could change. .PP \&\fBsk_TYPE_find_ex()\fR operates like \fBsk_TYPE_find()\fR except when a comparison function has been specified and no matching element is found. Instead of returning \fB\-1\fR, \fBsk_TYPE_find_ex()\fR returns the index of the element either before or after the location where \fBptr\fR would be if it were present in \fBsk\fR. .PP \&\fBsk_TYPE_sort()\fR sorts \fBsk\fR using the supplied comparison function. .PP \&\fBsk_TYPE_is_sorted()\fR returns \fB1\fR if \fBsk\fR is sorted and \fB0\fR otherwise. .PP \&\fBsk_TYPE_dup()\fR returns a copy of \fBsk\fR. Note the pointers in the copy are identical to the original. .PP \&\fBsk_TYPE_deep_copy()\fR returns a new stack where each element has been copied. Copying is performed by the supplied \fBcopyfunc()\fR and freeing by \fBfreefunc()\fR. The function \fBfreefunc()\fR is only called if an error occurs. .SH "NOTES" .IX Header "NOTES" Care should be taken when accessing stacks in multi-threaded environments. Any operation which increases the size of a stack such as \fBsk_TYPE_insert()\fR or \&\fBsk_push()\fR can \*(L"grow\*(R" the size of an internal array and cause race conditions if the same stack is accessed in a different thread. Operations such as \&\fBsk_find()\fR and \fBsk_sort()\fR can also reorder the stack. .PP Any comparison function supplied should use a metric suitable for use in a binary search operation. That is it should return zero, a positive or negative value if \fBa\fR is equal to, greater than or less than \fBb\fR respectively. .PP Care should be taken when checking the return values of the functions \&\fBsk_TYPE_find()\fR and \fBsk_TYPE_find_ex()\fR. They return an index to the matching element. In particular \fB0\fR indicates a matching first element. A failed search is indicated by a \fB\-1\fR return value. .PP \&\s-1\fBSTACK_OF\s0()\fR, \s-1\fBDEFINE_STACK_OF\s0()\fR, \s-1\fBDEFINE_STACK_OF_CONST\s0()\fR, and \&\s-1\fBDEFINE_SPECIAL_STACK_OF\s0()\fR are implemented as macros. .PP The underlying utility \fBOPENSSL_sk_\fR \s-1API\s0 should not be used directly. It defines these functions: \fBOPENSSL_sk_deep_copy()\fR, \&\fBOPENSSL_sk_delete()\fR, \fBOPENSSL_sk_delete_ptr()\fR, \fBOPENSSL_sk_dup()\fR, \&\fBOPENSSL_sk_find()\fR, \fBOPENSSL_sk_find_ex()\fR, \fBOPENSSL_sk_free()\fR, \&\fBOPENSSL_sk_insert()\fR, \fBOPENSSL_sk_is_sorted()\fR, \fBOPENSSL_sk_new()\fR, \&\fBOPENSSL_sk_new_null()\fR, \fBOPENSSL_sk_num()\fR, \fBOPENSSL_sk_pop()\fR, \&\fBOPENSSL_sk_pop_free()\fR, \fBOPENSSL_sk_push()\fR, \fBOPENSSL_sk_reserve()\fR, \&\fBOPENSSL_sk_set()\fR, \fBOPENSSL_sk_set_cmp_func()\fR, \fBOPENSSL_sk_shift()\fR, \&\fBOPENSSL_sk_sort()\fR, \fBOPENSSL_sk_unshift()\fR, \fBOPENSSL_sk_value()\fR, \&\fBOPENSSL_sk_zero()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBsk_TYPE_num()\fR returns the number of elements in the stack or \fB\-1\fR if the passed stack is \fB\s-1NULL\s0\fR. .PP \&\fBsk_TYPE_value()\fR returns a pointer to a stack element or \fB\s-1NULL\s0\fR if the index is out of range. .PP \&\fBsk_TYPE_new()\fR, \fBsk_TYPE_new_null()\fR and \fBsk_TYPE_new_reserve()\fR return an empty stack or \fB\s-1NULL\s0\fR if an error occurs. .PP \&\fBsk_TYPE_reserve()\fR returns \fB1\fR on successful allocation of the required memory or \fB0\fR on error. .PP \&\fBsk_TYPE_set_cmp_func()\fR returns the old comparison function or \fB\s-1NULL\s0\fR if there was no old comparison function. .PP \&\fBsk_TYPE_free()\fR, \fBsk_TYPE_zero()\fR, \fBsk_TYPE_pop_free()\fR and \fBsk_TYPE_sort()\fR do not return values. .PP \&\fBsk_TYPE_pop()\fR, \fBsk_TYPE_shift()\fR, \fBsk_TYPE_delete()\fR and \fBsk_TYPE_delete_ptr()\fR return a pointer to the deleted element or \fB\s-1NULL\s0\fR on error. .PP \&\fBsk_TYPE_insert()\fR, \fBsk_TYPE_push()\fR and \fBsk_TYPE_unshift()\fR return the total number of elements in the stack and 0 if an error occurred. \fBsk_TYPE_push()\fR further returns \-1 if \fBsk\fR is \fB\s-1NULL\s0\fR. .PP \&\fBsk_TYPE_set()\fR returns a pointer to the replacement element or \fB\s-1NULL\s0\fR on error. .PP \&\fBsk_TYPE_find()\fR and \fBsk_TYPE_find_ex()\fR return an index to the found element or \fB\-1\fR on error. .PP \&\fBsk_TYPE_is_sorted()\fR returns \fB1\fR if the stack is sorted and \fB0\fR if it is not. .PP \&\fBsk_TYPE_dup()\fR and \fBsk_TYPE_deep_copy()\fR return a pointer to the copy of the stack. .SH "HISTORY" .IX Header "HISTORY" Before OpenSSL 1.1.0, this was implemented via macros and not inline functions and was not a public \s-1API.\s0 .PP \&\fBsk_TYPE_reserve()\fR and \fBsk_TYPE_new_reserve()\fR were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2017 The OpenSSL Project Authors.

The functions \&\fBSSL_export_keying_material()\fR and \fBSSL_export_keying_material_early()\fR enable an application to use some of this keying material for its own purposes in accordance with \s-1RFC5705\s0 (for TLSv1.2 and below) or \s-1RFC8446\s0 (for TLSv1.3). .PP \&\fBSSL_export_keying_material()\fR derives keying material using the \fIexporter_master_secret\fR established in the handshake. .PP \&\fBSSL_export_keying_material_early()\fR is only usable with TLSv1.3, and derives keying material using the \fIearly_exporter_master_secret\fR (as defined in the \&\s-1TLS 1.3 RFC\s0). For the client, the \fIearly_exporter_master_secret\fR is only available when the client attempts to send 0\-RTT data. For the server, it is only available when the server accepts 0\-RTT data. .PP An application may need to securely establish the context within which this keying material will be used. For example this may include identifiers for the application session, application algorithms or parameters, or the lifetime of the context. The context value is left to the application but must be the same on both sides of the communication. .PP For a given \s-1SSL\s0 connection \fBs\fR, \fBolen\fR bytes of data will be written to \&\fBout\fR. The application specific context should be supplied in the location pointed to by \fBcontext\fR and should be \fBcontextlen\fR bytes long. Provision of a context is optional. If the context should be omitted entirely then \&\fBuse_context\fR should be set to 0. Otherwise it should be any other value. If \&\fBuse_context\fR is 0 then the values of \fBcontext\fR and \fBcontextlen\fR are ignored. Note that in TLSv1.2 and below a zero length context is treated differently from no context at all, and will result in different keying material being returned. In TLSv1.3 a zero length context is that same as no context at all and will result in the same keying material being returned. .PP An application specific label should be provided in the location pointed to by \&\fBlabel\fR and should be \fBllen\fR bytes long. Typically this will be a value from the \s-1IANA\s0 Exporter Label Registry (<https://www.iana.org/assignments/tls\-parameters/tls\-parameters.xhtml#exporter\-labels>). Alternatively labels beginning with \*(L"\s-1EXPERIMENTAL\*(R"\s0 are permitted by the standard to be used without registration. TLSv1.3 imposes a maximum label length of 249 bytes. .PP Note that this function is only defined for TLSv1.0 and above, and DTLSv1.0 and above. Attempting to use it in SSLv3 will result in an error. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_export_keying_material()\fR returns 0 or \-1 on failure or 1 on success. .PP \&\fBSSL_export_keying_material_early()\fR returns 0 on failure or 1 on success. .SH "HISTORY" .IX Header "HISTORY" The \fBSSL_export_keying_material_early()\fR function was added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2017\-2018 The OpenSSL Project Authors.

Through user-written methods (see \fBUI_create_method\fR\|(3)), prompting can be done in any way imaginable, be it plain text prompting, through dialog boxes or from a cell phone. .PP All the functions work through a context of the type \s-1UI.\s0 This context contains all the information needed to prompt correctly as well as a reference to a \s-1UI_METHOD,\s0 which is an ordered vector of functions that carry out the actual prompting. .PP The first thing to do is to create a \s-1UI\s0 with \fBUI_new()\fR or \fBUI_new_method()\fR, then add information to it with the UI_add or UI_dup functions. Also, user-defined random data can be passed down to the underlying method through calls to \fBUI_add_user_data()\fR or \fBUI_dup_user_data()\fR. The default \&\s-1UI\s0 method doesn't care about these data, but other methods might. Finally, use \fBUI_process()\fR to actually perform the prompting and \fBUI_get0_result()\fR and \fBUI_get_result_length()\fR to find the result to the prompt and its length. .PP A \s-1UI\s0 can contain more than one prompt, which are performed in the given sequence. Each prompt gets an index number which is returned by the UI_add and UI_dup functions, and has to be used to get the corresponding result with \fBUI_get0_result()\fR and \fBUI_get_result_length()\fR. .PP \&\fBUI_process()\fR can be called more than once on the same \s-1UI,\s0 thereby allowing a \s-1UI\s0 to have a long lifetime, but can just as well have a short lifetime. .PP The functions are as follows: .PP \&\fBUI_new()\fR creates a new \s-1UI\s0 using the default \s-1UI\s0 method. When done with this \s-1UI,\s0 it should be freed using \fBUI_free()\fR. .PP \&\fBUI_new_method()\fR creates a new \s-1UI\s0 using the given \s-1UI\s0 method. When done with this \s-1UI,\s0 it should be freed using \fBUI_free()\fR. .PP \&\fBUI_OpenSSL()\fR returns the built-in \s-1UI\s0 method (note: not necessarily the default one, since the default can be changed. See further on). This method is the most machine/OS dependent part of OpenSSL and normally generates the most problems when porting. .PP \&\fBUI_null()\fR returns a \s-1UI\s0 method that does nothing. Its use is to avoid getting internal defaults for passed \s-1UI_METHOD\s0 pointers. .PP \&\fBUI_free()\fR removes a \s-1UI\s0 from memory, along with all other pieces of memory that's connected to it, like duplicated input strings, results and others. If \fBui\fR is \s-1NULL\s0 nothing is done. .PP \&\fBUI_add_input_string()\fR and \fBUI_add_verify_string()\fR add a prompt to the \s-1UI,\s0 as well as flags and a result buffer and the desired minimum and maximum sizes of the result, not counting the final \s-1NUL\s0 character. The given information is used to prompt for information, for example a password, and to verify a password (i.e. having the user enter it twice and check that the same string was entered twice). \fBUI_add_verify_string()\fR takes and extra argument that should be a pointer to the result buffer of the input string that it's supposed to verify, or verification will fail. .PP \&\fBUI_add_input_boolean()\fR adds a prompt to the \s-1UI\s0 that's supposed to be answered in a boolean way, with a single character for yes and a different character for no. A set of characters that can be used to cancel the prompt is given as well. The prompt itself is divided in two, one part being the descriptive text (given through the \fIprompt\fR argument) and one describing the possible answers (given through the \fIaction_desc\fR argument). .PP \&\fBUI_add_info_string()\fR and \fBUI_add_error_string()\fR add strings that are shown at the same time as the prompt for extra information or to show an error string. The difference between the two is only conceptual. With the builtin method, there's no technical difference between them. Other methods may make a difference between them, however. .PP The flags currently supported are \fB\s-1UI_INPUT_FLAG_ECHO\s0\fR, which is relevant for \&\fBUI_add_input_string()\fR and will have the users response be echoed (when prompting for a password, this flag should obviously not be used, and \&\fB\s-1UI_INPUT_FLAG_DEFAULT_PWD\s0\fR, which means that a default password of some sort will be used (completely depending on the application and the \s-1UI\s0 method). .PP \&\fBUI_dup_input_string()\fR, \fBUI_dup_verify_string()\fR, \fBUI_dup_input_boolean()\fR, \&\fBUI_dup_info_string()\fR and \fBUI_dup_error_string()\fR are basically the same as their UI_add counterparts, except that they make their own copies of all strings. .PP \&\fBUI_construct_prompt()\fR is a helper function that can be used to create a prompt from two pieces of information: an description and a name. The default constructor (if there is none provided by the method used) creates a string "Enter \fIdescription\fR for \fIname\fR:\*(L". With the description \*(R"pass phrase\*(L" and the filename \*(R"foo.key\*(L", that becomes \&\*(R"Enter pass phrase for foo.key:". Other methods may create whatever string and may include encodings that will be processed by the other method functions. .PP \&\fBUI_add_user_data()\fR adds a user data pointer for the method to use at any time. The builtin \s-1UI\s0 method doesn't care about this info. Note that several calls to this function doesn't add data, it replaces the previous blob with the one given as argument. .PP \&\fBUI_dup_user_data()\fR duplicates the user data and works as an alternative to \fBUI_add_user_data()\fR when the user data needs to be preserved for a longer duration, perhaps even the lifetime of the application. The \s-1UI\s0 object takes ownership of this duplicate and will free it whenever it gets replaced or the \s-1UI\s0 is destroyed. \fBUI_dup_user_data()\fR returns 0 on success, or \-1 on memory allocation failure or if the method doesn't have a duplicator function. .PP \&\fBUI_get0_user_data()\fR retrieves the data that has last been given to the \&\s-1UI\s0 with \fBUI_add_user_data()\fR or UI_dup_user_data. .PP \&\fBUI_get0_result()\fR returns a pointer to the result buffer associated with the information indexed by \fIi\fR. .PP \&\fBUI_get_result_length()\fR returns the length of the result buffer associated with the information indexed by \fIi\fR. .PP \&\fBUI_process()\fR goes through the information given so far, does all the printing and prompting and returns the final status, which is \-2 on out-of-band events (Interrupt, Cancel, ...), \-1 on error and 0 on success. .PP \&\fBUI_ctrl()\fR adds extra control for the application author. For now, it understands two commands: \fB\s-1UI_CTRL_PRINT_ERRORS\s0\fR, which makes \fBUI_process()\fR print the OpenSSL error stack as part of processing the \s-1UI,\s0 and \&\fB\s-1UI_CTRL_IS_REDOABLE\s0\fR, which returns a flag saying if the used \s-1UI\s0 can be used again or not. .PP \&\fBUI_set_default_method()\fR changes the default \s-1UI\s0 method to the one given. This function is not thread-safe and should not be called at the same time as other OpenSSL functions. .PP \&\fBUI_get_default_method()\fR returns a pointer to the current default \s-1UI\s0 method. .PP \&\fBUI_get_method()\fR returns the \s-1UI\s0 method associated with a given \s-1UI.\s0 .PP \&\fBUI_set_method()\fR changes the \s-1UI\s0 method associated with a given \s-1UI.\s0 .SH "NOTES" .IX Header "NOTES" The resulting strings that the built in method \fBUI_OpenSSL()\fR generate are assumed to be encoded according to the current locale or (for Windows) code page. For applications having different demands, these strings need to be converted appropriately by the caller. For Windows, if the \s-1OPENSSL_WIN32_UTF8\s0 environment variable is set, the built-in method \fBUI_OpenSSL()\fR will produce \s-1UTF\-8\s0 encoded strings instead. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBUI_new()\fR and \fBUI_new_method()\fR return a valid \fB\s-1UI\s0\fR structure or \s-1NULL\s0 if an error occurred. .PP \&\fBUI_add_input_string()\fR, \fBUI_dup_input_string()\fR, \fBUI_add_verify_string()\fR, \&\fBUI_dup_verify_string()\fR, \fBUI_add_input_boolean()\fR, \fBUI_dup_input_boolean()\fR, \&\fBUI_add_info_string()\fR, \fBUI_dup_info_string()\fR, \fBUI_add_error_string()\fR and \fBUI_dup_error_string()\fR return a positive number on success or a value which is less than or equal to 0 otherwise. .PP \&\fBUI_construct_prompt()\fR returns a string or \s-1NULL\s0 if an error occurred. .PP \&\fBUI_dup_user_data()\fR returns 0 on success or \-1 on error. .PP \&\fBUI_get0_result()\fR returns a string or \s-1NULL\s0 on error. .PP \&\fBUI_get_result_length()\fR returns a positive integer or 0 on success; otherwise it returns \-1 on error. .PP \&\fBUI_process()\fR returns 0 on success or a negative value on error. .PP \&\fBUI_ctrl()\fR returns a mask on success or \-1 on error. .PP \&\fBUI_get_default_method()\fR, \fBUI_get_method()\fR, \fBUI_OpenSSL()\fR, \fBUI_null()\fR and \&\fBUI_set_method()\fR return either a valid \fB\s-1UI_METHOD\s0\fR structure or \s-1NULL\s0 respectively. .SH "HISTORY" .IX Header "HISTORY" The \fBUI_dup_user_data()\fR function was added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2020 The OpenSSL Project Authors.

At that point the code can be paused and control returns to user code until some subsequent event indicates that the job can be resumed. .PP The creation of an \s-1ASYNC_JOB\s0 is a relatively expensive operation. Therefore, for efficiency reasons, jobs can be created up front and reused many times. They are held in a pool until they are needed, at which point they are removed from the pool, used, and then returned to the pool when the job completes. If the user application is multi-threaded, then \fBASYNC_init_thread()\fR may be called for each thread that will initiate asynchronous jobs. Before user code exits per-thread resources need to be cleaned up. This will normally occur automatically (see \fBOPENSSL_init_crypto\fR\|(3)) but may be explicitly initiated by using \fBASYNC_cleanup_thread()\fR. No asynchronous jobs must be outstanding for the thread when \fBASYNC_cleanup_thread()\fR is called. Failing to ensure this will result in memory leaks. .PP The \fBmax_size\fR argument limits the number of ASYNC_JOBs that will be held in the pool. If \fBmax_size\fR is set to 0 then no upper limit is set. When an \&\s-1ASYNC_JOB\s0 is needed but there are none available in the pool already then one will be automatically created, as long as the total of ASYNC_JOBs managed by the pool does not exceed \fBmax_size\fR. When the pool is first initialised \&\fBinit_size\fR ASYNC_JOBs will be created immediately. If \fBASYNC_init_thread()\fR is not called before the pool is first used then it will be called automatically with a \fBmax_size\fR of 0 (no upper limit) and an \fBinit_size\fR of 0 (no ASYNC_JOBs created up front). .PP An asynchronous job is started by calling the \fBASYNC_start_job()\fR function. Initially \fB*job\fR should be \s-1NULL.\s0 \fBctx\fR should point to an \s-1ASYNC_WAIT_CTX\s0 object created through the \fBASYNC_WAIT_CTX_new\fR\|(3) function. \fBret\fR should point to a location where the return value of the asynchronous function should be stored on completion of the job. \fBfunc\fR represents the function that should be started asynchronously. The data pointed to by \fBargs\fR and of size \fBsize\fR will be copied and then passed as an argument to \fBfunc\fR when the job starts. ASYNC_start_job will return one of the following values: .IP "\fB\s-1ASYNC_ERR\s0\fR" 4 .IX Item "ASYNC_ERR" An error occurred trying to start the job. Check the OpenSSL error queue (e.g. see \fBERR_print_errors\fR\|(3)) for more details. .IP "\fB\s-1ASYNC_NO_JOBS\s0\fR" 4 .IX Item "ASYNC_NO_JOBS" There are no jobs currently available in the pool. This call can be retried again at a later time. .IP "\fB\s-1ASYNC_PAUSE\s0\fR" 4 .IX Item "ASYNC_PAUSE" The job was successfully started but was \*(L"paused\*(R" before it completed (see \&\fBASYNC_pause_job()\fR below). A handle to the job is placed in \fB*job\fR. Other work can be performed (if desired) and the job restarted at a later time. To restart a job call \fBASYNC_start_job()\fR again passing the job handle in \fB*job\fR. The \&\fBfunc\fR, \fBargs\fR and \fBsize\fR parameters will be ignored when restarting a job. When restarting a job \fBASYNC_start_job()\fR \fBmust\fR be called from the same thread that the job was originally started from. .IP "\fB\s-1ASYNC_FINISH\s0\fR" 4 .IX Item "ASYNC_FINISH" The job completed. \fB*job\fR will be \s-1NULL\s0 and the return value from \fBfunc\fR will be placed in \fB*ret\fR. .PP At any one time there can be a maximum of one job actively running per thread (you can have many that are paused). \fBASYNC_get_current_job()\fR can be used to get a pointer to the currently executing \s-1ASYNC_JOB.\s0 If no job is currently executing then this will return \s-1NULL.\s0 .PP If executing within the context of a job (i.e. having been called directly or indirectly by the function \*(L"func\*(R" passed as an argument to \fBASYNC_start_job()\fR) then \fBASYNC_pause_job()\fR will immediately return control to the calling application with \s-1ASYNC_PAUSE\s0 returned from the \fBASYNC_start_job()\fR call. A subsequent call to ASYNC_start_job passing in the relevant \s-1ASYNC_JOB\s0 in the \&\fB*job\fR parameter will resume execution from the \fBASYNC_pause_job()\fR call. If \&\fBASYNC_pause_job()\fR is called whilst not within the context of a job then no action is taken and \fBASYNC_pause_job()\fR returns immediately. .PP \&\fBASYNC_get_wait_ctx()\fR can be used to get a pointer to the \s-1ASYNC_WAIT_CTX\s0 for the \fBjob\fR. ASYNC_WAIT_CTXs can have a \*(L"wait\*(R" file descriptor associated with them. Applications can wait for the file descriptor to be ready for \*(L"read\*(R" using a system function call such as select or poll (being ready for \*(L"read\*(R" indicates that the job should be resumed). If no file descriptor is made available then an application will have to periodically \*(L"poll\*(R" the job by attempting to restart it to see if it is ready to continue. .PP An example of typical usage might be an async capable engine. User code would initiate cryptographic operations. The engine would initiate those operations asynchronously and then call \fBASYNC_WAIT_CTX_set_wait_fd\fR\|(3) followed by \&\fBASYNC_pause_job()\fR to return control to the user code. The user code can then perform other tasks or wait for the job to be ready by calling \*(L"select\*(R" or other similar function on the wait file descriptor. The engine can signal to the user code that the job should be resumed by making the wait file descriptor \&\*(L"readable\*(R". Once resumed the engine should clear the wake signal on the wait file descriptor. .PP The \fBASYNC_block_pause()\fR function will prevent the currently active job from pausing. The block will remain in place until a subsequent call to \&\fBASYNC_unblock_pause()\fR. These functions can be nested, e.g. if you call \&\fBASYNC_block_pause()\fR twice then you must call \fBASYNC_unblock_pause()\fR twice in order to re-enable pausing. If these functions are called while there is no currently active job then they have no effect. This functionality can be useful to avoid deadlock scenarios. For example during the execution of an \s-1ASYNC_JOB\s0 an application acquires a lock. It then calls some cryptographic function which invokes \fBASYNC_pause_job()\fR. This returns control back to the code that created the \s-1ASYNC_JOB.\s0 If that code then attempts to acquire the same lock before resuming the original job then a deadlock can occur. By calling \&\fBASYNC_block_pause()\fR immediately after acquiring the lock and \&\fBASYNC_unblock_pause()\fR immediately before releasing it then this situation cannot occur. .PP Some platforms cannot support async operations. The \fBASYNC_is_capable()\fR function can be used to detect whether the current platform is async capable or not. .SH "RETURN VALUES" .IX Header "RETURN VALUES" ASYNC_init_thread returns 1 on success or 0 otherwise. .PP ASYNC_start_job returns one of \s-1ASYNC_ERR, ASYNC_NO_JOBS, ASYNC_PAUSE\s0 or \&\s-1ASYNC_FINISH\s0 as described above. .PP ASYNC_pause_job returns 0 if an error occurred or 1 on success. If called when not within the context of an \s-1ASYNC_JOB\s0 then this is counted as success so 1 is returned. .PP ASYNC_get_current_job returns a pointer to the currently executing \s-1ASYNC_JOB\s0 or \&\s-1NULL\s0 if not within the context of a job. .PP \&\fBASYNC_get_wait_ctx()\fR returns a pointer to the \s-1ASYNC_WAIT_CTX\s0 for the job. .PP \&\fBASYNC_is_capable()\fR returns 1 if the current platform is async capable or 0 otherwise. .SH "NOTES" .IX Header "NOTES" On Windows platforms the openssl/async.h header is dependent on some of the types customarily made available by including windows.h. The application developer is likely to require control over when the latter is included, commonly as one of the first included headers. Therefore, it is defined as an application developer's responsibility to include windows.h prior to async.h. .SH "EXAMPLES" .IX Header "EXAMPLES" The following example demonstrates how to use most of the core async APIs: .PP .Vb 7 \& #ifdef _WIN32 \& # include <windows.h> \& #endif \& #include <stdio.h> \& #include <unistd.h> \& #include <openssl/async.h> \& #include <openssl/crypto.h> \& \& int unique = 0; \& \& void cleanup(ASYNC_WAIT_CTX *ctx, const void *key, OSSL_ASYNC_FD r, void *vw) \& { \& OSSL_ASYNC_FD *w = (OSSL_ASYNC_FD *)vw; \& \& close(r); \& close(*w); \& OPENSSL_free(w); \& } \& \& int jobfunc(void *arg) \& { \& ASYNC_JOB *currjob; \& unsigned char *msg; \& int pipefds[2] = {0, 0}; \& OSSL_ASYNC_FD *wptr; \& char buf = \*(AqX\*(Aq; \& \& currjob = ASYNC_get_current_job(); \& if (currjob != NULL) { \& printf("Executing within a job\en"); \& } else { \& printf("Not executing within a job \- should not happen\en"); \& return 0; \& } \& \& msg = (unsigned char *)arg; \& printf("Passed in message is: %s\en", msg); \& \& if (pipe(pipefds) != 0) { \& printf("Failed to create pipe\en"); \& return 0; \& } \& wptr = OPENSSL_malloc(sizeof(OSSL_ASYNC_FD)); \& if (wptr == NULL) { \& printf("Failed to malloc\en"); \& return 0; \& } \& *wptr = pipefds[1]; \& ASYNC_WAIT_CTX_set_wait_fd(ASYNC_get_wait_ctx(currjob), &unique, \& pipefds[0], wptr, cleanup); \& \& /* \& * Normally some external event would cause this to happen at some \& * later point \- but we do it here for demo purposes, i.e. \& * immediately signalling that the job is ready to be woken up after \& * we return to main via ASYNC_pause_job(). \& */ \& write(pipefds[1], &buf, 1); \& \& /* Return control back to main */ \& ASYNC_pause_job(); \& \& /* Clear the wake signal */ \& read(pipefds[0], &buf, 1); \& \& printf ("Resumed the job after a pause\en"); \& \& return 1; \& } \& \& int main(void) \& { \& ASYNC_JOB *job = NULL; \& ASYNC_WAIT_CTX *ctx = NULL; \& int ret; \& OSSL_ASYNC_FD waitfd; \& fd_set waitfdset; \& size_t numfds; \& unsigned char msg[13] = "Hello world!"; \& \& printf("Starting...\en"); \& \& ctx = ASYNC_WAIT_CTX_new(); \& if (ctx == NULL) { \& printf("Failed to create ASYNC_WAIT_CTX\en"); \& abort(); \& } \& \& for (;;) { \& switch (ASYNC_start_job(&job, ctx, &ret, jobfunc, msg, sizeof(msg))) { \& case ASYNC_ERR: \& case ASYNC_NO_JOBS: \& printf("An error occurred\en"); \& goto end; \& case ASYNC_PAUSE: \& printf("Job was paused\en"); \& break; \& case ASYNC_FINISH: \& printf("Job finished with return value %d\en", ret); \& goto end; \& } \& \& /* Wait for the job to be woken */ \& printf("Waiting for the job to be woken up\en"); \& \& if (!ASYNC_WAIT_CTX_get_all_fds(ctx, NULL, &numfds) \& || numfds > 1) { \& printf("Unexpected number of fds\en"); \& abort(); \& } \& ASYNC_WAIT_CTX_get_all_fds(ctx, &waitfd, &numfds); \& FD_ZERO(&waitfdset); \& FD_SET(waitfd, &waitfdset); \& select(waitfd + 1, &waitfdset, NULL, NULL, NULL); \& } \& \& end: \& ASYNC_WAIT_CTX_free(ctx); \& printf("Finishing\en"); \& \& return 0; \& } .Ve .PP The expected output from executing the above example program is: .PP .Vb 8 \& Starting... \& Executing within a job \& Passed in message is: Hello world! \& Job was paused \& Waiting for the job to be woken up \& Resumed the job after a pause \& Job finished with return value 1 \& Finishing .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBcrypto\fR\|(7), \fBERR_print_errors\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" ASYNC_init_thread, ASYNC_cleanup_thread, ASYNC_start_job, ASYNC_pause_job, ASYNC_get_current_job, \fBASYNC_get_wait_ctx()\fR, \&\fBASYNC_block_pause()\fR, \fBASYNC_unblock_pause()\fR and \fBASYNC_is_capable()\fR were first added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2015\-2020 The OpenSSL Project Authors.

Data written to a memory \s-1BIO\s0 is stored in a \s-1BUF_MEM\s0 structure which is extended as appropriate to accommodate the stored data. .PP \&\fBBIO_s_secmem()\fR is like \fBBIO_s_mem()\fR except that the secure heap is used for buffer storage. .PP Any data written to a memory \s-1BIO\s0 can be recalled by reading from it. Unless the memory \s-1BIO\s0 is read only any data read from it is deleted from the \s-1BIO.\s0 .PP Memory BIOs support \fBBIO_gets()\fR and \fBBIO_puts()\fR. .PP If the \s-1BIO_CLOSE\s0 flag is set when a memory \s-1BIO\s0 is freed then the underlying \&\s-1BUF_MEM\s0 structure is also freed. .PP Calling \fBBIO_reset()\fR on a read write memory \s-1BIO\s0 clears any data in it if the flag \s-1BIO_FLAGS_NONCLEAR_RST\s0 is not set, otherwise it just restores the read pointer to the state it was just after the last write was performed and the data can be read again. On a read only \s-1BIO\s0 it similarly restores the \s-1BIO\s0 to its original state and the read only data can be read again. .PP \&\fBBIO_eof()\fR is true if no data is in the \s-1BIO.\s0 .PP \&\fBBIO_ctrl_pending()\fR returns the number of bytes currently stored. .PP \&\fBBIO_set_mem_eof_return()\fR sets the behaviour of memory \s-1BIO\s0 \fBb\fR when it is empty. If the \fBv\fR is zero then an empty memory \s-1BIO\s0 will return \s-1EOF\s0 (that is it will return zero and BIO_should_retry(b) will be false. If \fBv\fR is non zero then it will return \fBv\fR when it is empty and it will set the read retry flag (that is BIO_read_retry(b) is true). To avoid ambiguity with a normal positive return value \fBv\fR should be set to a negative value, typically \-1. .PP \&\fBBIO_get_mem_data()\fR sets *\fBpp\fR to a pointer to the start of the memory BIOs data and returns the total amount of data available. It is implemented as a macro. .PP \&\fBBIO_set_mem_buf()\fR sets the internal \s-1BUF_MEM\s0 structure to \fBbm\fR and sets the close flag to \fBc\fR, that is \fBc\fR should be either \s-1BIO_CLOSE\s0 or \s-1BIO_NOCLOSE.\s0 It is a macro. .PP \&\fBBIO_get_mem_ptr()\fR places the underlying \s-1BUF_MEM\s0 structure in *\fBpp\fR. It is a macro. .PP \&\fBBIO_new_mem_buf()\fR creates a memory \s-1BIO\s0 using \fBlen\fR bytes of data at \fBbuf\fR, if \fBlen\fR is \-1 then the \fBbuf\fR is assumed to be nul terminated and its length is determined by \fBstrlen\fR. The \s-1BIO\s0 is set to a read only state and as a result cannot be written to. This is useful when some data needs to be made available from a static area of memory in the form of a \s-1BIO.\s0 The supplied data is read directly from the supplied buffer: it is \fBnot\fR copied first, so the supplied area of memory must be unchanged until the \s-1BIO\s0 is freed. .SH "NOTES" .IX Header "NOTES" Writes to memory BIOs will always succeed if memory is available: that is their size can grow indefinitely. .PP Every write after partial read (not all data in the memory buffer was read) to a read write memory \s-1BIO\s0 will have to move the unread data with an internal copy operation, if a \s-1BIO\s0 contains a lot of data and it is read in small chunks intertwined with writes the operation can be very slow. Adding a buffering \s-1BIO\s0 to the chain can speed up the process. .PP Calling \fBBIO_set_mem_buf()\fR on a \s-1BIO\s0 created with \fBBIO_new_secmem()\fR will give undefined results, including perhaps a program crash. .PP Switching the memory \s-1BIO\s0 from read write to read only is not supported and can give undefined results including a program crash. There are two notable exceptions to the rule. The first one is to assign a static memory buffer immediately after \s-1BIO\s0 creation and set the \s-1BIO\s0 as read only. .PP The other supported sequence is to start with read write \s-1BIO\s0 then temporarily switch it to read only and call \fBBIO_reset()\fR on the read only \s-1BIO\s0 immediately before switching it back to read write. Before the \s-1BIO\s0 is freed it must be switched back to the read write mode. .PP Calling \fBBIO_get_mem_ptr()\fR on read only \s-1BIO\s0 will return a \s-1BUF_MEM\s0 that contains only the remaining data to be read. If the close status of the \&\s-1BIO\s0 is set to \s-1BIO_NOCLOSE,\s0 before freeing the \s-1BUF_MEM\s0 the data pointer in it must be set to \s-1NULL\s0 as the data pointer does not point to an allocated memory. .PP Calling \fBBIO_reset()\fR on a read write memory \s-1BIO\s0 with \s-1BIO_FLAGS_NONCLEAR_RST\s0 flag set can have unexpected outcome when the reads and writes to the \&\s-1BIO\s0 are intertwined. As documented above the \s-1BIO\s0 will be reset to the state after the last completed write operation. The effects of reads preceding that write operation cannot be undone. .PP Calling \fBBIO_get_mem_ptr()\fR prior to a \fBBIO_reset()\fR call with \&\s-1BIO_FLAGS_NONCLEAR_RST\s0 set has the same effect as a write operation. .SH "BUGS" .IX Header "BUGS" There should be an option to set the maximum size of a memory \s-1BIO.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_s_mem()\fR and \fBBIO_s_secmem()\fR return a valid memory \fB\s-1BIO_METHOD\s0\fR structure. .PP \&\fBBIO_set_mem_eof_return()\fR, \fBBIO_set_mem_buf()\fR and \fBBIO_get_mem_ptr()\fR return 1 on success or a value which is less than or equal to 0 if an error occurred. .PP \&\fBBIO_get_mem_data()\fR returns the total number of bytes available on success, 0 if b is \s-1NULL,\s0 or a negative value in case of other errors. .PP \&\fBBIO_new_mem_buf()\fR returns a valid \fB\s-1BIO\s0\fR structure on success or \s-1NULL\s0 on error. .SH "EXAMPLES" .IX Header "EXAMPLES" Create a memory \s-1BIO\s0 and write some data to it: .PP .Vb 1 \& BIO *mem = BIO_new(BIO_s_mem()); \& \& BIO_puts(mem, "Hello World\en"); .Ve .PP Create a read only memory \s-1BIO:\s0 .PP .Vb 2 \& char data[] = "Hello World"; \& BIO *mem = BIO_new_mem_buf(data, \-1); .Ve .PP Extract the \s-1BUF_MEM\s0 structure from a memory \s-1BIO\s0 and then free up the \s-1BIO:\s0 .PP .Vb 1 \& BUF_MEM *bptr; \& \& BIO_get_mem_ptr(mem, &bptr); \& BIO_set_close(mem, BIO_NOCLOSE); /* So BIO_free() leaves BUF_MEM alone */ \& BIO_free(mem); .Ve .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2019 The OpenSSL Project Authors.

The modes \&\s-1GCM, CCM, XTS,\s0 and \s-1OCB\s0 are unsupported. \fBiter\fR is the encryption algorithm iteration count to use and \fBmac_iter\fR is the \s-1MAC\s0 iteration count to use. \&\fBkeytype\fR is the type of key. .SH "NOTES" .IX Header "NOTES" The parameters \fBnid_key\fR, \fBnid_cert\fR, \fBiter\fR, \fBmac_iter\fR and \fBkeytype\fR can all be set to zero and sensible defaults will be used. .PP These defaults are: 40 bit \s-1RC2\s0 encryption for certificates, triple \s-1DES\s0 encryption for private keys, a key iteration count of \s-1PKCS12_DEFAULT_ITER\s0 (currently 2048) and a \s-1MAC\s0 iteration count of 1. .PP The default \s-1MAC\s0 iteration count is 1 in order to retain compatibility with old software which did not interpret \s-1MAC\s0 iteration counts. If such compatibility is not required then \fBmac_iter\fR should be set to \s-1PKCS12_DEFAULT_ITER.\s0 .PP \&\fBkeytype\fR adds a flag to the store private key. This is a non standard extension that is only currently interpreted by \s-1MSIE.\s0 If set to zero the flag is omitted, if set to \fB\s-1KEY_SIG\s0\fR the key can be used for signing only, if set to \fB\s-1KEY_EX\s0\fR it can be used for signing and encryption. This option was useful for old export grade software which could use signing only keys of arbitrary size but had restrictions on the permissible sizes of keys which could be used for encryption. .PP If a certificate contains an \fBalias\fR or \fBkeyid\fR then this will be used for the corresponding \fBfriendlyName\fR or \fBlocalKeyID\fR in the \&\s-1PKCS12\s0 structure. .PP Either \fBpkey\fR, \fBcert\fR or both can be \fB\s-1NULL\s0\fR to indicate that no key or certificate is required. In previous versions both had to be present or a fatal error is returned. .PP \&\fBnid_key\fR or \fBnid_cert\fR can be set to \-1 indicating that no encryption should be used. .PP \&\fBmac_iter\fR can be set to \-1 and the \s-1MAC\s0 will then be omitted entirely. .PP \&\fBPKCS12_create()\fR makes assumptions regarding the encoding of the given pass phrase.

A triplet contains three members, \fBr\fR, \fBd\fR and \fBt\fR. \fBr\fR is the additional prime besides \fBp\fR and \fBq\fR. \fBd\fR and \&\fBt\fR are the exponent and coefficient for \s-1CRT\s0 calculations. .PP The \fBn\fR, \fBe\fR and \fBd\fR parameters can be obtained by calling \&\fBRSA_get0_key()\fR. If they have not been set yet, then \fB*n\fR, \fB*e\fR and \&\fB*d\fR will be set to \s-1NULL.\s0 Otherwise, they are set to pointers to their respective values. These point directly to the internal representations of the values and therefore should not be freed by the caller. .PP The \fBn\fR, \fBe\fR and \fBd\fR parameter values can be set by calling \&\fBRSA_set0_key()\fR and passing the new values for \fBn\fR, \fBe\fR and \fBd\fR as parameters to the function. The values \fBn\fR and \fBe\fR must be non-NULL the first time this function is called on a given \s-1RSA\s0 object. The value \fBd\fR may be \s-1NULL.\s0 On subsequent calls any of these values may be \&\s-1NULL\s0 which means the corresponding \s-1RSA\s0 field is left untouched. Calling this function transfers the memory management of the values to the \s-1RSA\s0 object, and therefore the values that have been passed in should not be freed by the caller after this function has been called. .PP In a similar fashion, the \fBp\fR and \fBq\fR parameters can be obtained and set with \fBRSA_get0_factors()\fR and \fBRSA_set0_factors()\fR, and the \fBdmp1\fR, \&\fBdmq1\fR and \fBiqmp\fR parameters can be obtained and set with \&\fBRSA_get0_crt_params()\fR and \fBRSA_set0_crt_params()\fR. .PP For \fBRSA_get0_key()\fR, \fBRSA_get0_factors()\fR, and \fBRSA_get0_crt_params()\fR, \&\s-1NULL\s0 value \s-1BIGNUM\s0 ** output parameters are permitted. The functions ignore \s-1NULL\s0 parameters but return values for other, non-NULL, parameters. .PP For multi-prime \s-1RSA,\s0 \fBRSA_get0_multi_prime_factors()\fR and \fBRSA_get0_multi_prime_params()\fR can be used to obtain other primes and related \s-1CRT\s0 parameters. The return values are stored in an array of \fB\s-1BIGNUM\s0 *\fR. \fBRSA_set0_multi_prime_params()\fR sets a collect of multi-prime 'triplet' members (prime, exponent and coefficient) into an \s-1RSA\s0 object. .PP Any of the values \fBn\fR, \fBe\fR, \fBd\fR, \fBp\fR, \fBq\fR, \fBdmp1\fR, \fBdmq1\fR, and \fBiqmp\fR can also be retrieved separately by the corresponding function \&\fBRSA_get0_n()\fR, \fBRSA_get0_e()\fR, \fBRSA_get0_d()\fR, \fBRSA_get0_p()\fR, \fBRSA_get0_q()\fR, \&\fBRSA_get0_dmp1()\fR, \fBRSA_get0_dmq1()\fR, and \fBRSA_get0_iqmp()\fR, respectively. .PP \&\fBRSA_get0_pss_params()\fR is used to retrieve the RSA-PSS parameters. .PP \&\fBRSA_set_flags()\fR sets the flags in the \fBflags\fR parameter on the \s-1RSA\s0 object. Multiple flags can be passed in one go (bitwise ORed together). Any flags that are already set are left set. \fBRSA_test_flags()\fR tests to see whether the flags passed in the \fBflags\fR parameter are currently set in the \s-1RSA\s0 object. Multiple flags can be tested in one go. All flags that are currently set are returned, or zero if none of the flags are set. \fBRSA_clear_flags()\fR clears the specified flags within the \&\s-1RSA\s0 object. .PP \&\fBRSA_get0_engine()\fR returns a handle to the \s-1ENGINE\s0 that has been set for this \s-1RSA\s0 object, or \s-1NULL\s0 if no such \s-1ENGINE\s0 has been set. .PP \&\fBRSA_get_version()\fR returns the version of an \s-1RSA\s0 object \fBr\fR. .SH "NOTES" .IX Header "NOTES" Values retrieved with \fBRSA_get0_key()\fR are owned by the \s-1RSA\s0 object used in the call and may therefore \fInot\fR be passed to \fBRSA_set0_key()\fR. If needed, duplicate the received value using \fBBN_dup()\fR and pass the duplicate. The same applies to \fBRSA_get0_factors()\fR and \fBRSA_set0_factors()\fR as well as \fBRSA_get0_crt_params()\fR and \fBRSA_set0_crt_params()\fR. .PP The caller should obtain the size by calling \fBRSA_get_multi_prime_extra_count()\fR in advance and allocate sufficient buffer to store the return values before calling \fBRSA_get0_multi_prime_factors()\fR and \fBRSA_get0_multi_prime_params()\fR. .PP \&\fBRSA_set0_multi_prime_params()\fR always clears the original multi-prime triplets in \s-1RSA\s0 object \fBr\fR and assign the new set of triplets into it. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBRSA_set0_key()\fR, \fBRSA_set0_factors()\fR, \fBRSA_set0_crt_params()\fR and \&\fBRSA_set0_multi_prime_params()\fR return 1 on success or 0 on failure. .PP \&\fBRSA_get0_n()\fR, \fBRSA_get0_e()\fR, \fBRSA_get0_d()\fR, \fBRSA_get0_p()\fR, \fBRSA_get0_q()\fR, \&\fBRSA_get0_dmp1()\fR, \fBRSA_get0_dmq1()\fR, and \fBRSA_get0_iqmp()\fR return the respective value. .PP \&\fBRSA_get0_multi_prime_factors()\fR and \fBRSA_get0_multi_prime_crt_params()\fR return 1 on success or 0 on failure. .PP \&\fBRSA_get_multi_prime_extra_count()\fR returns two less than the number of primes in use, which is 0 for traditional \s-1RSA\s0 and the number of extra primes for multi-prime \s-1RSA.\s0 .PP \&\fBRSA_get_version()\fR returns \fB\s-1RSA_ASN1_VERSION_MULTI\s0\fR for multi-prime \s-1RSA\s0 and \&\fB\s-1RSA_ASN1_VERSION_DEFAULT\s0\fR for normal two-prime \s-1RSA,\s0 as defined in \s-1RFC 8017.\s0 .PP \&\fBRSA_test_flags()\fR returns the current state of the flags in the \s-1RSA\s0 object. .PP \&\fBRSA_get0_engine()\fR returns the \s-1ENGINE\s0 set for the \s-1RSA\s0 object or \s-1NULL\s0 if no \&\s-1ENGINE\s0 has been set. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBRSA_new\fR\|(3), \fBRSA_size\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The \fBRSA_get0_pss_params()\fR function was added in OpenSSL 1.1.1e. .PP The \&\fBRSA_get_multi_prime_extra_count()\fR, \fBRSA_get0_multi_prime_factors()\fR, \&\fBRSA_get0_multi_prime_crt_params()\fR, \fBRSA_set0_multi_prime_params()\fR, and \fBRSA_get_version()\fR functions were added in OpenSSL 1.1.1. .PP Other functions described here were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2018 The OpenSSL Project Authors.

The \s-1OCSP\s0 protocol does not require that this certificate is included in the \fBcerts\fR field of the response, so additional certificates can be supplied in \fBextra_certs\fR if the certificates that may have signed the response are known via some out-of-band mechanism. .PP \&\fBOCSP_resp_get0_id()\fR gets the responder id of \fBbs\fR. If the responder \s-1ID\s0 is a name then <*pname> is set to the name and \fB*pid\fR is set to \s-1NULL.\s0 If the responder \s-1ID\s0 is by key \s-1ID\s0 then \fB*pid\fR is set to the key \s-1ID\s0 and \fB*pname\fR is set to \s-1NULL.\s0 \fBOCSP_resp_get1_id()\fR leaves ownership of \fB*pid\fR and \fB*pname\fR with the caller, who is responsible for freeing them. Both functions return 1 in case of success and 0 in case of failure. If \fBOCSP_resp_get1_id()\fR returns 0, no freeing of the results is necessary. .PP \&\fBOCSP_check_validity()\fR checks the validity of \fBthisupd\fR and \fBnextupd\fR values which will be typically obtained from \fBOCSP_resp_find_status()\fR or \&\fBOCSP_single_get0_status()\fR. If \fBsec\fR is nonzero it indicates how many seconds leeway should be allowed in the check. If \fBmaxsec\fR is positive it indicates the maximum age of \fBthisupd\fR in seconds. .PP \&\fBOCSP_basic_verify()\fR checks that the basic response message \fBbs\fR is correctly signed and that the signer certificate can be validated. It takes \fBst\fR as the trusted store and \fBcerts\fR as a set of untrusted intermediate certificates. The function first tries to find the signer certificate of the response in <certs>. It also searches the certificates the responder may have included in \fBbs\fR unless the \fBflags\fR contain \fB\s-1OCSP_NOINTERN\s0\fR. It fails if the signer certificate cannot be found. Next, the function checks the signature of \fBbs\fR and fails on error unless the \fBflags\fR contain \fB\s-1OCSP_NOSIGS\s0\fR.

Otherwise the function continues by validating the signer certificate. To this end, all certificates in \fBcert\fR and in \fBbs\fR are considered as untrusted certificates for the construction of the validation path for the signer certificate unless the \fB\s-1OCSP_NOCHAIN\s0\fR flag is set. After successful path validation the function returns success if the \fB\s-1OCSP_NOCHECKS\s0\fR flag is set. Otherwise it verifies that the signer certificate meets the \s-1OCSP\s0 issuer criteria including potential delegation. If this does not succeed and the \&\fBflags\fR do not contain \fB\s-1OCSP_NOEXPLICIT\s0\fR the function checks for explicit trust for \s-1OCSP\s0 signing in the root \s-1CA\s0 certificate. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOCSP_resp_find_status()\fR returns 1 if \fBid\fR is found in \fBbs\fR and 0 otherwise. .PP \&\fBOCSP_resp_count()\fR returns the total number of \fB\s-1OCSP_SINGLERESP\s0\fR fields in \&\fBbs\fR. .PP \&\fBOCSP_resp_get0()\fR returns a pointer to an \fB\s-1OCSP_SINGLERESP\s0\fR structure or \&\fB\s-1NULL\s0\fR if \fBidx\fR is out of range. .PP \&\fBOCSP_resp_find()\fR returns the index of \fBid\fR in \fBbs\fR (which may be 0) or \-1 if \&\fBid\fR was not found. .PP \&\fBOCSP_single_get0_status()\fR returns the status of \fBsingle\fR or \-1 if an error occurred. .PP \&\fBOCSP_resp_get0_signer()\fR returns 1 if the signing certificate was located, or 0 on error. .PP \&\fBOCSP_basic_verify()\fR returns 1 on success, 0 on error, or \-1 on fatal error such as malloc failure. .SH "NOTES" .IX Header "NOTES" Applications will typically call \fBOCSP_resp_find_status()\fR using the certificate \&\s-1ID\s0 of interest and then check its validity using \fBOCSP_check_validity()\fR. They can then take appropriate action based on the status of the certificate. .PP An \s-1OCSP\s0 response for a certificate contains \fBthisUpdate\fR and \fBnextUpdate\fR fields. Normally the current time should be between these two values. To account for clock skew the \fBmaxsec\fR field can be set to nonzero in \&\fBOCSP_check_validity()\fR. Some responders do not set the \fBnextUpdate\fR field, this would otherwise mean an ancient response would be considered valid: the \&\fBmaxsec\fR parameter to \fBOCSP_check_validity()\fR can be used to limit the permitted age of responses. .PP The values written to \fB*revtime\fR, \fB*thisupd\fR and \fB*nextupd\fR by \&\fBOCSP_resp_find_status()\fR and \fBOCSP_single_get0_status()\fR are internal pointers which \fB\s-1MUST NOT\s0\fR be freed up by the calling application.

For example, this can occur because a session is considered faulty or has become obsolete because of exceeding the timeout value. .PP \&\fBSSL_CTX_sess_set_get_cb()\fR sets the callback function that is called whenever a \s-1TLS\s0 client proposed to resume a session but the session could not be found in the internal session cache (see \&\fBSSL_CTX_set_session_cache_mode\fR\|(3)). (\s-1TLS\s0 server only.) .PP \&\fBSSL_CTX_sess_get_new_cb()\fR, \fBSSL_CTX_sess_get_remove_cb()\fR, and \&\fBSSL_CTX_sess_get_get_cb()\fR retrieve the function pointers set by the corresponding set callback functions. If a callback function has not been set, the \s-1NULL\s0 pointer is returned. .SH "NOTES" .IX Header "NOTES" In order to allow external session caching, synchronization with the internal session cache is realized via callback functions. Inside these callback functions, session can be saved to disk or put into a database using the \&\fBd2i_SSL_SESSION\fR\|(3) interface. .PP The \fBnew_session_cb()\fR is called whenever a new session has been negotiated and session caching is enabled (see \fBSSL_CTX_set_session_cache_mode\fR\|(3)). The \&\fBnew_session_cb()\fR is passed the \fBssl\fR connection and the nascent ssl session \fBsess\fR. Since sessions are reference-counted objects, the reference count on the session is incremented before the callback, on behalf of the application. If the callback returns \fB0\fR, the session will be immediately removed from the internal cache and the reference count released. If the callback returns \fB1\fR, the application retains the reference (for an entry in the application-maintained \*(L"external session cache\*(R"), and is responsible for calling \fBSSL_SESSION_free()\fR when the session reference is no longer in use. .PP Note that in TLSv1.3, sessions are established after the main handshake has completed. The server decides when to send the client the session information and this may occur some time after the end of the handshake (or not at all). This means that applications should expect the \fBnew_session_cb()\fR function to be invoked during the handshake (for <= TLSv1.2) or after the handshake (for TLSv1.3). It is also possible in TLSv1.3 for multiple sessions to be established with a single connection. In these case the \fBnew_session_cb()\fR function will be invoked multiple times. .PP In TLSv1.3 it is recommended that each \s-1SSL_SESSION\s0 object is only used for resumption once. One way of enforcing that is for applications to call \&\fBSSL_CTX_remove_session\fR\|(3) after a session has been used. .PP The \fBremove_session_cb()\fR is called whenever the \s-1SSL\s0 engine removes a session from the internal cache. This can happen when the session is removed because it is expired or when a connection was not shutdown cleanly. It also happens for all sessions in the internal session cache when \&\fBSSL_CTX_free\fR\|(3) is called. The \fBremove_session_cb()\fR is passed the \fBctx\fR and the ssl session \fBsess\fR. It does not provide any feedback. .PP The \fBget_session_cb()\fR is only called on \s-1SSL/TLS\s0 servers, and is given the session id proposed by the client. The \fBget_session_cb()\fR is always called, even when session caching was disabled. The \fBget_session_cb()\fR is passed the \&\fBssl\fR connection and the session id of length \fBlength\fR at the memory location \&\fBdata\fR. By setting the parameter \fBcopy\fR to \fB1\fR, the callback can require the \&\s-1SSL\s0 engine to increment the reference count of the \s-1SSL_SESSION\s0 object; setting \fBcopy\fR to \fB0\fR causes the reference count to remain unchanged.

It provides a set of functions used by OpenSSL for the implementation of various X509 and X509_CRL lookup capabilities. One instance of an X509_LOOKUP_METHOD can be associated to many instantiations of an \&\fBX509_LOOKUP\fR structure. .PP \&\fBX509_LOOKUP_meth_new()\fR creates a new \fBX509_LOOKUP_METHOD\fR structure. It should be given a human-readable string containing a brief description of the lookup method. .PP \&\fBX509_LOOKUP_meth_free()\fR destroys a \fBX509_LOOKUP_METHOD\fR structure. .PP \&\fBX509_LOOKUP_get_new_item()\fR and \fBX509_LOOKUP_set_new_item()\fR get and set the function that is called when an \fBX509_LOOKUP\fR object is created with \&\fBX509_LOOKUP_new()\fR. If an X509_LOOKUP_METHOD requires any per\-X509_LOOKUP specific data, the supplied new_item function should allocate this data and invoke \fBX509_LOOKUP_set_method_data\fR\|(3). .PP \&\fBX509_LOOKUP_get_free()\fR and \fBX509_LOOKUP_set_free()\fR get and set the function that is used to free any method data that was allocated and set from within new_item function. .PP \&\fBX509_LOOKUP_meth_get_init()\fR and \fBX509_LOOKUP_meth_set_init()\fR get and set the function that is used to initialize the method data that was set with \&\fBX509_LOOKUP_set_method_data\fR\|(3) as part of the new_item routine. .PP \&\fBX509_LOOKUP_meth_get_shutdown()\fR and \fBX509_LOOKUP_meth_set_shutdown()\fR get and set the function that is used to shut down the method data whose state was previously initialized in the init function. .PP \&\fBX509_LOOKUP_meth_get_ctrl()\fR and \fBX509_LOOKUP_meth_set_ctrl()\fR get and set a function to be used to handle arbitrary control commands issued by \&\fBX509_LOOKUP_ctrl()\fR. The control function is given the X509_LOOKUP \&\fBctx\fR, along with the arguments passed by X509_LOOKUP_ctrl. \fBcmd\fR is an arbitrary integer that defines some operation. \fBargc\fR is a pointer to an array of characters. \fBargl\fR is an integer. \fBret\fR, if set, points to a location where any return data should be written to. How \&\fBargc\fR and \fBargl\fR are used depends entirely on the control function. .PP \&\fBX509_LOOKUP_set_get_by_subject()\fR, \fBX509_LOOKUP_set_get_by_issuer_serial()\fR, \&\fBX509_LOOKUP_set_get_by_fingerprint()\fR, \fBX509_LOOKUP_set_get_by_alias()\fR set the functions used to retrieve an X509 or X509_CRL object by the object's subject, issuer, fingerprint, and alias respectively. These functions are given the X509_LOOKUP context, the type of the X509_OBJECT being requested, parameters related to the lookup, and an X509_OBJECT that will receive the requested object. .PP Implementations must add objects they find to the \fBX509_STORE\fR object using \fBX509_STORE_add_cert()\fR or \fBX509_STORE_add_crl()\fR. This increments its reference count. However, the \fBX509_STORE_CTX_get_by_subject()\fR function also increases the reference count which leads to one too many references being held. Therefore, applications should additionally call \fBX509_free()\fR or \fBX509_CRL_free()\fR to decrement the reference count again. .PP Implementations should also use either \fBX509_OBJECT_set1_X509()\fR or \&\fBX509_OBJECT_set1_X509_CRL()\fR to set the result. Note that this also increments the result's reference count. .PP Any method data that was created as a result of the new_item function set by \fBX509_LOOKUP_meth_set_new_item()\fR can be accessed with \&\fBX509_LOOKUP_get_method_data\fR\|(3). The \fBX509_STORE\fR object that owns the X509_LOOKUP may be accessed with \fBX509_LOOKUP_get_store\fR\|(3). Successful lookups should return 1, and unsuccessful lookups should return 0. .PP \&\fBX509_LOOKUP_get_get_by_subject()\fR, \fBX509_LOOKUP_get_get_by_issuer_serial()\fR, \&\fBX509_LOOKUP_get_get_by_fingerprint()\fR, \fBX509_LOOKUP_get_get_by_alias()\fR retrieve the function set by the corresponding setter. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The \fBX509_LOOKUP_meth_set\fR functions return 1 on success or 0 on error. .PP The \fBX509_LOOKUP_meth_get\fR functions return the corresponding function pointers. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBX509_STORE_new\fR\|(3), \fBSSL_CTX_set_cert_store\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The functions described here were added in OpenSSL 1.1.0i. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2018\-2020 The OpenSSL Project Authors.

The first is the generation of a \fIDES_key_schedule\fR from a key, the second is the actual encryption. A \s-1DES\s0 key is of type \fIDES_cblock\fR. This type consists of 8 bytes with odd parity. The least significant bit in each byte is the parity bit. The key schedule is an expanded form of the key; it is used to speed the encryption process. .PP \&\fBDES_random_key()\fR generates a random key. The random generator must be seeded when calling this function. If the automatic seeding or reseeding of the OpenSSL \s-1CSPRNG\s0 fails due to external circumstances (see \s-1\fBRAND\s0\fR\|(7)), the operation will fail. If the function fails, 0 is returned. .PP Before a \s-1DES\s0 key can be used, it must be converted into the architecture dependent \fIDES_key_schedule\fR via the \&\fBDES_set_key_checked()\fR or \fBDES_set_key_unchecked()\fR function. .PP \&\fBDES_set_key_checked()\fR will check that the key passed is of odd parity and is not a weak or semi-weak key. If the parity is wrong, then \-1 is returned. If the key is a weak key, then \-2 is returned. If an error is returned, the key schedule is not generated. .PP \&\fBDES_set_key()\fR works like \&\fBDES_set_key_checked()\fR if the \fIDES_check_key\fR flag is nonzero, otherwise like \fBDES_set_key_unchecked()\fR. These functions are available for compatibility; it is recommended to use a function that does not depend on a global variable. .PP \&\fBDES_set_odd_parity()\fR sets the parity of the passed \fIkey\fR to odd. .PP \&\fBDES_is_weak_key()\fR returns 1 if the passed key is a weak key, 0 if it is ok. .PP The following routines mostly operate on an input and output stream of \&\fIDES_cblock\fRs. .PP \&\fBDES_ecb_encrypt()\fR is the basic \s-1DES\s0 encryption routine that encrypts or decrypts a single 8\-byte \fIDES_cblock\fR in \fIelectronic code book\fR (\s-1ECB\s0) mode. It always transforms the input data, pointed to by \&\fIinput\fR, into the output data, pointed to by the \fIoutput\fR argument. If the \fIencrypt\fR argument is nonzero (\s-1DES_ENCRYPT\s0), the \fIinput\fR (cleartext) is encrypted in to the \fIoutput\fR (ciphertext) using the key_schedule specified by the \fIschedule\fR argument, previously set via \&\fIDES_set_key\fR. If \fIencrypt\fR is zero (\s-1DES_DECRYPT\s0), the \fIinput\fR (now ciphertext) is decrypted into the \fIoutput\fR (now cleartext). Input and output may overlap. \fBDES_ecb_encrypt()\fR does not return a value. .PP \&\fBDES_ecb3_encrypt()\fR encrypts/decrypts the \fIinput\fR block by using three-key Triple-DES encryption in \s-1ECB\s0 mode. This involves encrypting the input with \fIks1\fR, decrypting with the key schedule \fIks2\fR, and then encrypting with \fIks3\fR. This routine greatly reduces the chances of brute force breaking of \s-1DES\s0 and has the advantage of if \fIks1\fR, \&\fIks2\fR and \fIks3\fR are the same, it is equivalent to just encryption using \s-1ECB\s0 mode and \fIks1\fR as the key. .PP The macro \fBDES_ecb2_encrypt()\fR is provided to perform two-key Triple-DES encryption by using \fIks1\fR for the final encryption. .PP \&\fBDES_ncbc_encrypt()\fR encrypts/decrypts using the \fIcipher-block-chaining\fR (\s-1CBC\s0) mode of \s-1DES.\s0 If the \fIencrypt\fR argument is nonzero, the routine cipher-block-chain encrypts the cleartext data pointed to by the \fIinput\fR argument into the ciphertext pointed to by the \fIoutput\fR argument, using the key schedule provided by the \fIschedule\fR argument, and initialization vector provided by the \fIivec\fR argument. If the \&\fIlength\fR argument is not an integral multiple of eight bytes, the last block is copied to a temporary area and zero filled. The output is always an integral multiple of eight bytes. .PP \&\fBDES_xcbc_encrypt()\fR is \s-1RSA\s0's \s-1DESX\s0 mode of \s-1DES.\s0 It uses \fIinw\fR and \&\fIoutw\fR to 'whiten' the encryption. \fIinw\fR and \fIoutw\fR are secret (unlike the iv) and are as such, part of the key. So the key is sort of 24 bytes. This is much better than \s-1CBC DES.\s0 .PP \&\fBDES_ede3_cbc_encrypt()\fR implements outer triple \s-1CBC DES\s0 encryption with three keys. This means that each \s-1DES\s0 operation inside the \s-1CBC\s0 mode is \&\f(CW\*(C`C=E(ks3,D(ks2,E(ks1,M)))\*(C'\fR. This mode is used by \s-1SSL.\s0 .PP The \fBDES_ede2_cbc_encrypt()\fR macro implements two-key Triple-DES by reusing \fIks1\fR for the final encryption. \f(CW\*(C`C=E(ks1,D(ks2,E(ks1,M)))\*(C'\fR. This form of Triple-DES is used by the \s-1RSAREF\s0 library. .PP \&\fBDES_pcbc_encrypt()\fR encrypts/decrypts using the propagating cipher block chaining mode used by Kerberos v4. Its parameters are the same as \&\fBDES_ncbc_encrypt()\fR. .PP \&\fBDES_cfb_encrypt()\fR encrypts/decrypts using cipher feedback mode. This method takes an array of characters as input and outputs an array of characters. It does not require any padding to 8 character groups. Note: the \fIivec\fR variable is changed and the new changed value needs to be passed to the next call to this function. Since this function runs a complete \s-1DES ECB\s0 encryption per \fInumbits\fR, this function is only suggested for use when sending a small number of characters. .PP \&\fBDES_cfb64_encrypt()\fR implements \s-1CFB\s0 mode of \s-1DES\s0 with 64\-bit feedback. Why is this useful you ask? Because this routine will allow you to encrypt an arbitrary number of bytes, without 8 byte padding. Each call to this routine will encrypt the input bytes to output and then update ivec and num. num contains 'how far' we are though ivec. If this does not make much sense, read more about \s-1CFB\s0 mode of \s-1DES.\s0 .PP \&\fBDES_ede3_cfb64_encrypt()\fR and \fBDES_ede2_cfb64_encrypt()\fR is the same as \&\fBDES_cfb64_encrypt()\fR except that Triple-DES is used. .PP \&\fBDES_ofb_encrypt()\fR encrypts using output feedback mode. This method takes an array of characters as input and outputs an array of characters. It does not require any padding to 8 character groups. Note: the \fIivec\fR variable is changed and the new changed value needs to be passed to the next call to this function. Since this function runs a complete \s-1DES ECB\s0 encryption per \fInumbits\fR, this function is only suggested for use when sending a small number of characters. .PP \&\fBDES_ofb64_encrypt()\fR is the same as \fBDES_cfb64_encrypt()\fR using Output Feed Back mode. .PP \&\fBDES_ede3_ofb64_encrypt()\fR and \fBDES_ede2_ofb64_encrypt()\fR is the same as \&\fBDES_ofb64_encrypt()\fR, using Triple-DES. .PP The following functions are included in the \s-1DES\s0 library for compatibility with the \s-1MIT\s0 Kerberos library. .PP \&\fBDES_cbc_cksum()\fR produces an 8 byte checksum based on the input stream (via \s-1CBC\s0 encryption). The last 4 bytes of the checksum are returned and the complete 8 bytes are placed in \fIoutput\fR. This function is used by Kerberos v4. Other applications should use \&\fBEVP_DigestInit\fR\|(3) etc. instead. .PP \&\fBDES_quad_cksum()\fR is a Kerberos v4 function. It returns a 4 byte checksum from the input bytes. The algorithm can be iterated over the input, depending on \fIout_count\fR, 1, 2, 3 or 4 times. If \fIoutput\fR is non-NULL, the 8 bytes generated by each pass are written into \&\fIoutput\fR. .PP The following are DES-based transformations: .PP \&\fBDES_fcrypt()\fR is a fast version of the Unix \fBcrypt\fR\|(3) function. This version takes only a small amount of space relative to other fast \&\fBcrypt()\fR implementations. This is different to the normal \fBcrypt()\fR in that the third parameter is the buffer that the return value is written into. It needs to be at least 14 bytes long. This function is thread safe, unlike the normal \fBcrypt()\fR. .PP \&\fBDES_crypt()\fR is a faster replacement for the normal system \fBcrypt()\fR. This function calls \fBDES_fcrypt()\fR with a static array passed as the third parameter. This mostly emulates the normal non-thread-safe semantics of \fBcrypt\fR\|(3). The \fBsalt\fR must be two \s-1ASCII\s0 characters. .PP The values returned by \fBDES_fcrypt()\fR and \fBDES_crypt()\fR are terminated by \s-1NUL\s0 character. .PP \&\fBDES_enc_write()\fR writes \fIlen\fR bytes to file descriptor \fIfd\fR from buffer \fIbuf\fR. The data is encrypted via \fIpcbc_encrypt\fR (default) using \fIsched\fR for the key and \fIiv\fR as a starting vector. The actual data send down \fIfd\fR consists of 4 bytes (in network byte order) containing the length of the following encrypted data. The encrypted data then follows, padded with random data out to a multiple of 8 bytes. .SH "BUGS" .IX Header "BUGS" \&\fBDES_cbc_encrypt()\fR does not modify \fBivec\fR; use \fBDES_ncbc_encrypt()\fR instead. .PP \&\fBDES_cfb_encrypt()\fR and \fBDES_ofb_encrypt()\fR operates on input of 8 bits. What this means is that if you set numbits to 12, and length to 2, the first 12 bits will come from the 1st input byte and the low half of the second input byte. The second 12 bits will have the low 8 bits taken from the 3rd input byte and the top 4 bits taken from the 4th input byte. The same holds for output. This function has been implemented this way because most people will be using a multiple of 8 and because once you get into pulling bytes input bytes apart things get ugly! .PP \&\fBDES_string_to_key()\fR is available for backward compatibility with the \&\s-1MIT\s0 library. New applications should use a cryptographic hash function. The same applies for \fBDES_string_to_2key()\fR. .SH "NOTES" .IX Header "NOTES" The \fBdes\fR library was written to be source code compatible with the \s-1MIT\s0 Kerberos library. .PP Applications should use the higher level functions \&\fBEVP_EncryptInit\fR\|(3) etc. instead of calling these functions directly. .PP Single-key \s-1DES\s0 is insecure due to its short key size. \s-1ECB\s0 mode is not suitable for most applications; see \fBdes_modes\fR\|(7). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBDES_set_key()\fR, \fBDES_key_sched()\fR, \fBDES_set_key_checked()\fR and \fBDES_is_weak_key()\fR return 0 on success or negative values on error. .PP \&\fBDES_cbc_cksum()\fR and \fBDES_quad_cksum()\fR return 4\-byte integer representing the last 4 bytes of the checksum of the input. .PP \&\fBDES_fcrypt()\fR returns a pointer to the caller-provided buffer and \fBDES_crypt()\fR \- to a static buffer on success; otherwise they return \s-1NULL.\s0 .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBdes_modes\fR\|(7), \&\fBEVP_EncryptInit\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The requirement that the \fBsalt\fR parameter to \fBDES_crypt()\fR and \fBDES_fcrypt()\fR be two \s-1ASCII\s0 characters was first enforced in OpenSSL 1.1.0. Previous versions tried to use the letter uppercase \fBA\fR if both character were not present, and could crash when given non-ASCII on some platforms. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

These functions are not normally called directly, various macros are used instead. The standard macros are described below, macros specific to a particular type of \s-1BIO\s0 are described in the specific BIOs manual page as well as any special features of the standard calls. .PP \&\fBBIO_reset()\fR typically resets a \s-1BIO\s0 to some initial state, in the case of file related BIOs for example it rewinds the file pointer to the start of the file. .PP \&\fBBIO_seek()\fR resets a file related \s-1BIO\s0's (that is file descriptor and \&\s-1FILE\s0 BIOs) file position pointer to \fBofs\fR bytes from start of file. .PP \&\fBBIO_tell()\fR returns the current file position of a file related \s-1BIO.\s0 .PP \&\fBBIO_flush()\fR normally writes out any internally buffered data, in some cases it is used to signal \s-1EOF\s0 and that no more data will be written. .PP \&\fBBIO_eof()\fR returns 1 if the \s-1BIO\s0 has read \s-1EOF,\s0 the precise meaning of \&\*(L"\s-1EOF\*(R"\s0 varies according to the \s-1BIO\s0 type. .PP \&\fBBIO_set_close()\fR sets the \s-1BIO\s0 \fBb\fR close flag to \fBflag\fR. \fBflag\fR can take the value \s-1BIO_CLOSE\s0 or \s-1BIO_NOCLOSE.\s0 Typically \s-1BIO_CLOSE\s0 is used in a source/sink \s-1BIO\s0 to indicate that the underlying I/O stream should be closed when the \s-1BIO\s0 is freed. .PP \&\fBBIO_get_close()\fR returns the BIOs close flag. .PP \&\fBBIO_pending()\fR, \fBBIO_ctrl_pending()\fR, \fBBIO_wpending()\fR and \fBBIO_ctrl_wpending()\fR return the number of pending characters in the BIOs read and write buffers. Not all BIOs support these calls. \fBBIO_ctrl_pending()\fR and \fBBIO_ctrl_wpending()\fR return a size_t type and are functions, \fBBIO_pending()\fR and \fBBIO_wpending()\fR are macros which call \fBBIO_ctrl()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_reset()\fR normally returns 1 for success and 0 or \-1 for failure. File BIOs are an exception, they return 0 for success and \-1 for failure. .PP \&\fBBIO_seek()\fR and \fBBIO_tell()\fR both return the current file position on success and \-1 for failure, except file BIOs which for \fBBIO_seek()\fR always return 0 for success and \-1 for failure. .PP \&\fBBIO_flush()\fR returns 1 for success and 0 or \-1 for failure. .PP \&\fBBIO_eof()\fR returns 1 if \s-1EOF\s0 has been reached 0 otherwise. .PP \&\fBBIO_set_close()\fR always returns 1. .PP \&\fBBIO_get_close()\fR returns the close flag value: \s-1BIO_CLOSE\s0 or \s-1BIO_NOCLOSE.\s0 .PP \&\fBBIO_pending()\fR, \fBBIO_ctrl_pending()\fR, \fBBIO_wpending()\fR and \fBBIO_ctrl_wpending()\fR return the amount of pending data. .SH "NOTES" .IX Header "NOTES" \&\fBBIO_flush()\fR, because it can write data may return 0 or \-1 indicating that the call should be retried later in a similar manner to \fBBIO_write_ex()\fR. The \fBBIO_should_retry()\fR call should be used and appropriate action taken is the call fails. .PP The return values of \fBBIO_pending()\fR and \fBBIO_wpending()\fR may not reliably determine the amount of pending data in all cases. For example in the case of a file \s-1BIO\s0 some data may be available in the \s-1FILE\s0 structures internal buffers but it is not possible to determine this in a portably way. For other types of \s-1BIO\s0 they may not be supported. .PP Filter BIOs if they do not internally handle a particular \fBBIO_ctrl()\fR operation usually pass the operation to the next \s-1BIO\s0 in the chain. This often means there is no need to locate the required \s-1BIO\s0 for a particular operation, it can be called on a chain and it will be automatically passed to the relevant \s-1BIO.\s0 However, this can cause unexpected results: for example no current filter BIOs implement \&\fBBIO_seek()\fR, but this may still succeed if the chain ends in a \s-1FILE\s0 or file descriptor \s-1BIO.\s0 .PP Source/sink BIOs return an 0 if they do not recognize the \fBBIO_ctrl()\fR operation. .SH "BUGS" .IX Header "BUGS" Some of the return values are ambiguous and care should be taken. In particular a return value of 0 can be returned if an operation is not supported, if an error occurred, if \s-1EOF\s0 has not been reached and in the case of \fBBIO_seek()\fR on a file \s-1BIO\s0 for a successful operation. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2022 The OpenSSL Project Authors.

The new chain may include some of the same BIOs from the old chain or it may be completely different. .SH "NOTES" .IX Header "NOTES" The names of these functions are perhaps a little misleading. \fBBIO_push()\fR joins two \s-1BIO\s0 chains whereas \fBBIO_pop()\fR deletes a single \s-1BIO\s0 from a chain, the deleted \s-1BIO\s0 does not need to be at the end of a chain. .PP The process of calling \fBBIO_push()\fR and \fBBIO_pop()\fR on a \s-1BIO\s0 may have additional consequences (a control call is made to the affected BIOs). Any effects will be noted in the descriptions of individual BIOs. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_push()\fR returns the head of the chain, which usually is \fIb\fR, or \fInext\fR if \fIb\fR is \s-1NULL.\s0 .PP \&\fBBIO_pop()\fR returns the next \s-1BIO\s0 in the chain, or \s-1NULL\s0 if there is no next \s-1BIO.\s0 .SH "EXAMPLES" .IX Header "EXAMPLES" For these examples suppose \fImd1\fR and \fImd2\fR are digest BIOs, \&\fIb64\fR is a base64 \s-1BIO\s0 and \fIf\fR is a file \s-1BIO.\s0 .PP If the call: .PP .Vb 1 \& BIO_push(b64, f); .Ve .PP is made then the new chain will be \fIb64\-f\fR. After making the calls .PP .Vb 2 \& BIO_push(md2, b64); \& BIO_push(md1, md2); .Ve .PP the new chain is \fImd1\-md2\-b64\-f\fR. Data written to \fImd1\fR will be digested by \fImd1\fR and \fImd2\fR, base64 encoded, and finally written to \fIf\fR. .PP It should be noted that reading causes data to pass in the reverse direction, that is data is read from \fIf\fR, base64 decoded, and digested by \fImd2\fR and then \fImd1\fR. .PP The call: .PP .Vb 1 \& BIO_pop(md2); .Ve .PP will return \fIb64\fR and the new chain will be \fImd1\-b64\-f\fR.

These functions support parameter \fItype\fR, which can be one of constants \fB\s-1FILETYPE_PEM\s0\fR, \fB\s-1FILETYPE_ASN1\s0\fR and \&\fB\s-1FILETYPE_DEFAULT\s0\fR. They load certificates and/or CRLs from specified file into memory cache of \fBX509_STORE\fR objects which given \fBctx\fR parameter is associated with. .PP Functions \fBX509_load_cert_file\fR and \&\fBX509_load_crl_file\fR can load both \s-1PEM\s0 and \s-1DER\s0 formats depending of type value. Because \s-1DER\s0 format cannot contain more than one certificate or \s-1CRL\s0 object (while \s-1PEM\s0 can contain several concatenated \s-1PEM\s0 objects) \&\fBX509_load_cert_crl_file\fR with \fB\s-1FILETYPE_ASN1\s0\fR is equivalent to \&\fBX509_load_cert_file\fR. .PP Constant \fB\s-1FILETYPE_DEFAULT\s0\fR with \s-1NULL\s0 filename causes these functions to load default certificate store file (see \&\fBX509_STORE_set_default_paths\fR\|(3). .PP Functions return number of objects loaded from file or 0 in case of error. .PP Both methods support adding several certificate locations into one \&\fBX509_STORE\fR. .PP This page documents certificate store formats used by these methods and caching policy. .SS "File Method" .IX Subsection "File Method" The \fBX509_LOOKUP_file\fR method loads all the certificates or CRLs present in a file into memory at the time the file is added as a lookup source. .PP File format is \s-1ASCII\s0 text which contains concatenated \s-1PEM\s0 certificates and CRLs. .PP This method should be used by applications which work with a small set of CAs. .SS "Hashed Directory Method" .IX Subsection "Hashed Directory Method" \&\fBX509_LOOKUP_hash_dir\fR is a more advanced method, which loads certificates and CRLs on demand, and caches them in memory once they are loaded. As of OpenSSL 1.0.0, it also checks for newer CRLs upon each lookup, so that newer CRLs are as soon as they appear in the directory. .PP The directory should contain one certificate or \s-1CRL\s0 per file in \s-1PEM\s0 format, with a filename of the form \fIhash\fR.\fIN\fR for a certificate, or \&\fIhash\fR.\fBr\fR\fIN\fR for a \s-1CRL.\s0 The \fIhash\fR is the value returned by the \fBX509_NAME_hash\fR\|(3) function applied to the subject name for certificates or issuer name for CRLs. The hash can also be obtained via the \fB\-hash\fR option of the \fBx509\fR\|(1) or \&\fBcrl\fR\|(1) commands. .PP The .\fIN\fR or .\fBr\fR\fIN\fR suffix is a sequence number that starts at zero, and is incremented consecutively for each certificate or \s-1CRL\s0 with the same \fIhash\fR value. Gaps in the sequence numbers are not supported, it is assumed that there are no more objects with the same hash beyond the first missing number in the sequence. .PP Sequence numbers make it possible for the directory to contain multiple certificates with same subject name hash value. For example, it is possible to have in the store several certificates with same subject or several CRLs with same issuer (and, for example, different validity period). .PP When checking for new CRLs once one \s-1CRL\s0 for given hash value is loaded, hash_dir lookup method checks only for certificates with sequence number greater than that of the already cached \s-1CRL.\s0 .PP Note that the hash algorithm used for subject name hashing changed in OpenSSL 1.0.0, and all certificate stores have to be rehashed when moving from OpenSSL 0.9.8 to 1.0.0. .PP OpenSSL includes a \fBrehash\fR\|(1) utility which creates symlinks with correct hashed names for all files with .pem suffix in a given directory. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBX509_LOOKUP_hash_dir()\fR and \fBX509_LOOKUP_file()\fR always return a valid \&\fBX509_LOOKUP_METHOD\fR structure. .PP \&\fBX509_load_cert_file()\fR, \fBX509_load_crl_file()\fR and \fBX509_load_cert_crl_file()\fR return the number of loaded objects or 0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBPEM_read_PrivateKey\fR\|(3), \&\fBX509_STORE_load_locations\fR\|(3), \&\fBX509_store_add_lookup\fR\|(3), \&\fBSSL_CTX_load_verify_locations\fR\|(3), \&\fBX509_LOOKUP_meth_new\fR\|(3), .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2015\-2020 The OpenSSL Project Authors.

If \fBc\fR is not \s-1NULL\s0 it should be of type (int *). .PP \&\fBBIO_set_conn_hostname()\fR uses the string \fBname\fR to set the hostname. The hostname can be an \s-1IP\s0 address; if the address is an IPv6 one, it must be enclosed with brackets. The hostname can also include the port in the form hostname:port. .PP \&\fBBIO_set_conn_port()\fR sets the port to \fBport\fR. \fBport\fR can be the numerical form or a string such as \*(L"http\*(R". A string will be looked up first using \fBgetservbyname()\fR on the host platform but if that fails a standard table of port names will be used. This internal list is http, telnet, socks, https, ssl, ftp, and gopher. .PP \&\fBBIO_set_conn_address()\fR sets the address and port information using a \s-1\fBBIO_ADDR\s0\fR\|(3ssl). .PP \&\fBBIO_set_conn_ip_family()\fR sets the \s-1IP\s0 family. .PP \&\fBBIO_get_conn_hostname()\fR returns the hostname of the connect \s-1BIO\s0 or \&\s-1NULL\s0 if the \s-1BIO\s0 is initialized but no hostname is set. This return value is an internal pointer which should not be modified. .PP \&\fBBIO_get_conn_port()\fR returns the port as a string. This return value is an internal pointer which should not be modified. .PP \&\fBBIO_get_conn_address()\fR returns the address information as a \s-1BIO_ADDR.\s0 This return value is an internal pointer which should not be modified. .PP \&\fBBIO_get_conn_ip_family()\fR returns the \s-1IP\s0 family of the connect \s-1BIO.\s0 .PP \&\fBBIO_set_nbio()\fR sets the non blocking I/O flag to \fBn\fR. If \fBn\fR is zero then blocking I/O is set. If \fBn\fR is 1 then non blocking I/O is set. Blocking I/O is the default. The call to \fBBIO_set_nbio()\fR should be made before the connection is established because non blocking I/O is set during the connect process. .PP \&\fBBIO_new_connect()\fR combines \fBBIO_new()\fR and \fBBIO_set_conn_hostname()\fR into a single call: that is it creates a new connect \s-1BIO\s0 with \fBname\fR. .PP \&\fBBIO_do_connect()\fR attempts to connect the supplied \s-1BIO.\s0 It returns 1 if the connection was established successfully. A zero or negative value is returned if the connection could not be established, the call \fBBIO_should_retry()\fR should be used for non blocking connect BIOs to determine if the call should be retried. .SH "NOTES" .IX Header "NOTES" If blocking I/O is set then a non positive return value from any I/O call is caused by an error condition, although a zero return will normally mean that the connection was closed. .PP If the port name is supplied as part of the hostname then this will override any value set with \fBBIO_set_conn_port()\fR. This may be undesirable if the application does not wish to allow connection to arbitrary ports. This can be avoided by checking for the presence of the ':' character in the passed hostname and either indicating an error or truncating the string at that point. .PP The values returned by \fBBIO_get_conn_hostname()\fR, \fBBIO_get_conn_address()\fR, and \fBBIO_get_conn_port()\fR are updated when a connection attempt is made. Before any connection attempt the values returned are those set by the application itself. .PP Applications do not have to call \fBBIO_do_connect()\fR but may wish to do so to separate the connection process from other I/O processing. .PP If non blocking I/O is set then retries will be requested as appropriate. .PP It addition to \fBBIO_should_read()\fR and \fBBIO_should_write()\fR it is also possible for \fBBIO_should_io_special()\fR to be true during the initial connection process with the reason \s-1BIO_RR_CONNECT.\s0 If this is returned then this is an indication that a connection attempt would block, the application should then take appropriate action to wait until the underlying socket has connected and retry the call. .PP \&\fBBIO_set_conn_hostname()\fR, \fBBIO_set_conn_port()\fR, \fBBIO_get_conn_hostname()\fR, \&\fBBIO_set_conn_address()\fR, \fBBIO_get_conn_port()\fR, \fBBIO_get_conn_address()\fR, \&\fBBIO_set_conn_ip_family()\fR, \fBBIO_get_conn_ip_family()\fR, \&\fBBIO_set_nbio()\fR, and \fBBIO_do_connect()\fR are macros. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_s_connect()\fR returns the connect \s-1BIO\s0 method. .PP \&\fBBIO_get_fd()\fR returns the socket or \-1 if the \s-1BIO\s0 has not been initialized. .PP \&\fBBIO_set_conn_address()\fR, \fBBIO_set_conn_port()\fR, and \fBBIO_set_conn_ip_family()\fR always return 1. .PP \&\fBBIO_set_conn_hostname()\fR returns 1 on success and 0 on failure. .PP \&\fBBIO_get_conn_address()\fR returns the address information or \s-1NULL\s0 if none was set. .PP \&\fBBIO_get_conn_hostname()\fR returns the connected hostname or \s-1NULL\s0 if none was set. .PP \&\fBBIO_get_conn_ip_family()\fR returns the address family or \-1 if none was set. .PP \&\fBBIO_get_conn_port()\fR returns a string representing the connected port or \s-1NULL\s0 if not set. .PP \&\fBBIO_set_nbio()\fR always returns 1. .PP \&\fBBIO_do_connect()\fR returns 1 if the connection was successfully established and 0 or \-1 if the connection failed. .SH "EXAMPLES" .IX Header "EXAMPLES" This is example connects to a webserver on the local host and attempts to retrieve a page and copy the result to standard output. .PP .Vb 3 \& BIO *cbio, *out; \& int len; \& char tmpbuf[1024]; \& \& cbio = BIO_new_connect("localhost:http"); \& out = BIO_new_fp(stdout, BIO_NOCLOSE); \& if (BIO_do_connect(cbio) <= 0) { \& fprintf(stderr, "Error connecting to server\en"); \& ERR_print_errors_fp(stderr); \& exit(1); \& } \& BIO_puts(cbio, "GET / HTTP/1.0\en\en"); \& for (;;) { \& len = BIO_read(cbio, tmpbuf, 1024); \& if (len <= 0) \& break; \& BIO_write(out, tmpbuf, len); \& } \& BIO_free(cbio); \& BIO_free(out); .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\s-1\fBBIO_ADDR\s0\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fBBIO_set_conn_int_port()\fR, \fBBIO_get_conn_int_port()\fR, \fBBIO_set_conn_ip()\fR, and \fBBIO_get_conn_ip()\fR were removed in OpenSSL 1.1.0.

These objects act as containers for implementations of cryptographic algorithms, and support a reference-counted mechanism to allow them to be dynamically loaded in and out of the running application. .PP The cryptographic functionality that can be provided by an \fB\s-1ENGINE\s0\fR implementation includes the following abstractions; .PP .Vb 6 \& RSA_METHOD \- for providing alternative RSA implementations \& DSA_METHOD, DH_METHOD, RAND_METHOD, ECDH_METHOD, ECDSA_METHOD, \& \- similarly for other OpenSSL APIs \& EVP_CIPHER \- potentially multiple cipher algorithms (indexed by \*(Aqnid\*(Aq) \& EVP_DIGEST \- potentially multiple hash algorithms (indexed by \*(Aqnid\*(Aq) \& key\-loading \- loading public and/or private EVP_PKEY keys .Ve .SS "Reference counting and handles" .IX Subsection "Reference counting and handles" Due to the modular nature of the \s-1ENGINE API,\s0 pointers to ENGINEs need to be treated as handles \- i.e. not only as pointers, but also as references to the underlying \s-1ENGINE\s0 object. Ie. one should obtain a new reference when making copies of an \s-1ENGINE\s0 pointer if the copies will be used (and released) independently. .PP \&\s-1ENGINE\s0 objects have two levels of reference-counting to match the way in which the objects are used. At the most basic level, each \s-1ENGINE\s0 pointer is inherently a \fBstructural\fR reference \- a structural reference is required to use the pointer value at all, as this kind of reference is a guarantee that the structure can not be deallocated until the reference is released. .PP However, a structural reference provides no guarantee that the \s-1ENGINE\s0 is initialised and able to use any of its cryptographic implementations. Indeed it's quite possible that most ENGINEs will not initialise at all in typical environments, as ENGINEs are typically used to support specialised hardware. To use an \s-1ENGINE\s0's functionality, you need a \&\fBfunctional\fR reference. This kind of reference can be considered a specialised form of structural reference, because each functional reference implicitly contains a structural reference as well \- however to avoid difficult-to-find programming bugs, it is recommended to treat the two kinds of reference independently. If you have a functional reference to an \&\s-1ENGINE,\s0 you have a guarantee that the \s-1ENGINE\s0 has been initialised and is ready to perform cryptographic operations, and will remain initialised until after you have released your reference. .PP \&\fIStructural references\fR .PP This basic type of reference is used for instantiating new ENGINEs, iterating across OpenSSL's internal linked-list of loaded ENGINEs, reading information about an \s-1ENGINE,\s0 etc. Essentially a structural reference is sufficient if you only need to query or manipulate the data of an \s-1ENGINE\s0 implementation rather than use its functionality. .PP The \fBENGINE_new()\fR function returns a structural reference to a new (empty) \&\s-1ENGINE\s0 object. There are other \s-1ENGINE API\s0 functions that return structural references such as; \fBENGINE_by_id()\fR, \fBENGINE_get_first()\fR, \fBENGINE_get_last()\fR, \&\fBENGINE_get_next()\fR, \fBENGINE_get_prev()\fR. All structural references should be released by a corresponding to call to the \fBENGINE_free()\fR function \- the \&\s-1ENGINE\s0 object itself will only actually be cleaned up and deallocated when the last structural reference is released. .PP It should also be noted that many \s-1ENGINE API\s0 function calls that accept a structural reference will internally obtain another reference \- typically this happens whenever the supplied \s-1ENGINE\s0 will be needed by OpenSSL after the function has returned. Eg. the function to add a new \s-1ENGINE\s0 to OpenSSL's internal list is \fBENGINE_add()\fR \- if this function returns success, then OpenSSL will have stored a new structural reference internally so the caller is still responsible for freeing their own reference with \&\fBENGINE_free()\fR when they are finished with it. In a similar way, some functions will automatically release the structural reference passed to it if part of the function's job is to do so. Eg. the \fBENGINE_get_next()\fR and \&\fBENGINE_get_prev()\fR functions are used for iterating across the internal \&\s-1ENGINE\s0 list \- they will return a new structural reference to the next (or previous) \s-1ENGINE\s0 in the list or \s-1NULL\s0 if at the end (or beginning) of the list, but in either case the structural reference passed to the function is released on behalf of the caller. .PP To clarify a particular function's handling of references, one should always consult that function's documentation \*(L"man\*(R" page, or failing that the openssl/engine.h header file includes some hints. .PP \&\fIFunctional references\fR .PP As mentioned, functional references exist when the cryptographic functionality of an \s-1ENGINE\s0 is required to be available. A functional reference can be obtained in one of two ways; from an existing structural reference to the required \s-1ENGINE,\s0 or by asking OpenSSL for the default operational \s-1ENGINE\s0 for a given cryptographic purpose. .PP To obtain a functional reference from an existing structural reference, call the \fBENGINE_init()\fR function. This returns zero if the \s-1ENGINE\s0 was not already operational and couldn't be successfully initialised (e.g. lack of system drivers, no special hardware attached, etc), otherwise it will return nonzero to indicate that the \s-1ENGINE\s0 is now operational and will have allocated a new \fBfunctional\fR reference to the \s-1ENGINE.\s0 All functional references are released by calling \fBENGINE_finish()\fR (which removes the implicit structural reference as well). .PP The second way to get a functional reference is by asking OpenSSL for a default implementation for a given task, e.g. by \fBENGINE_get_default_RSA()\fR, \&\fBENGINE_get_default_cipher_engine()\fR, etc. These are discussed in the next section, though they are not usually required by application programmers as they are used automatically when creating and using the relevant algorithm-specific types in OpenSSL, such as \s-1RSA, DSA, EVP_CIPHER_CTX,\s0 etc. .SS "Default implementations" .IX Subsection "Default implementations" For each supported abstraction, the \s-1ENGINE\s0 code maintains an internal table of state to control which implementations are available for a given abstraction and which should be used by default. These implementations are registered in the tables and indexed by an 'nid' value, because abstractions like \s-1EVP_CIPHER\s0 and \s-1EVP_DIGEST\s0 support many distinct algorithms and modes, and ENGINEs can support arbitrarily many of them. In the case of other abstractions like \s-1RSA, DSA,\s0 etc, there is only one \&\*(L"algorithm\*(R" so all implementations implicitly register using the same 'nid' index. .PP When a default \s-1ENGINE\s0 is requested for a given abstraction/algorithm/mode, (e.g. when calling RSA_new_method(\s-1NULL\s0)), a \*(L"get_default\*(R" call will be made to the \&\s-1ENGINE\s0 subsystem to process the corresponding state table and return a functional reference to an initialised \s-1ENGINE\s0 whose implementation should be used. If no \s-1ENGINE\s0 should (or can) be used, it will return \s-1NULL\s0 and the caller will operate with a \s-1NULL ENGINE\s0 handle \- this usually equates to using the conventional software implementation. In the latter case, OpenSSL will from then on behave the way it used to before the \s-1ENGINE API\s0 existed. .PP Each state table has a flag to note whether it has processed this \&\*(L"get_default\*(R" query since the table was last modified, because to process this question it must iterate across all the registered ENGINEs in the table trying to initialise each of them in turn, in case one of them is operational. If it returns a functional reference to an \s-1ENGINE,\s0 it will also cache another reference to speed up processing future queries (without needing to iterate across the table). Likewise, it will cache a \s-1NULL\s0 response if no \s-1ENGINE\s0 was available so that future queries won't repeat the same iteration unless the state table changes. This behaviour can also be changed; if the \s-1ENGINE_TABLE_FLAG_NOINIT\s0 flag is set (using \&\fBENGINE_set_table_flags()\fR), no attempted initialisations will take place, instead the only way for the state table to return a non-NULL \s-1ENGINE\s0 to the \&\*(L"get_default\*(R" query will be if one is expressly set in the table. Eg. \&\fBENGINE_set_default_RSA()\fR does the same job as \fBENGINE_register_RSA()\fR except that it also sets the state table's cached response for the \*(L"get_default\*(R" query. In the case of abstractions like \s-1EVP_CIPHER,\s0 where implementations are indexed by 'nid', these flags and cached-responses are distinct for each 'nid' value. .SS "Application requirements" .IX Subsection "Application requirements" This section will explain the basic things an application programmer should support to make the most useful elements of the \s-1ENGINE\s0 functionality available to the user. The first thing to consider is whether the programmer wishes to make alternative \s-1ENGINE\s0 modules available to the application and user. OpenSSL maintains an internal linked list of \&\*(L"visible\*(R" ENGINEs from which it has to operate \- at start-up, this list is empty and in fact if an application does not call any \s-1ENGINE API\s0 calls and it uses static linking against openssl, then the resulting application binary will not contain any alternative \s-1ENGINE\s0 code at all. So the first consideration is whether any/all available \s-1ENGINE\s0 implementations should be made visible to OpenSSL \- this is controlled by calling the various \*(L"load\*(R" functions. .PP The fact that ENGINEs are made visible to OpenSSL (and thus are linked into the program and loaded into memory at run-time) does not mean they are \&\*(L"registered\*(R" or called into use by OpenSSL automatically \- that behaviour is something for the application to control. Some applications will want to allow the user to specify exactly which \s-1ENGINE\s0 they want used if any is to be used at all. Others may prefer to load all support and have OpenSSL automatically use at run-time any \s-1ENGINE\s0 that is able to successfully initialise \- i.e. to assume that this corresponds to acceleration hardware attached to the machine or some such thing. There are probably numerous other ways in which applications may prefer to handle things, so we will simply illustrate the consequences as they apply to a couple of simple cases and leave developers to consider these and the source code to openssl's builtin utilities as guides. .PP If no \s-1ENGINE API\s0 functions are called within an application, then OpenSSL will not allocate any internal resources. Prior to OpenSSL 1.1.0, however, if any ENGINEs are loaded, even if not registered or used, it was necessary to call \fBENGINE_cleanup()\fR before the program exits. .PP \&\fIUsing a specific \s-1ENGINE\s0 implementation\fR .PP Here we'll assume an application has been configured by its user or admin to want to use the \*(L"\s-1ACME\*(R" ENGINE\s0 if it is available in the version of OpenSSL the application was compiled with. If it is available, it should be used by default for all \s-1RSA, DSA,\s0 and symmetric cipher operations, otherwise OpenSSL should use its builtin software as per usual. The following code illustrates how to approach this; .PP .Vb 10 \& ENGINE *e; \& const char *engine_id = "ACME"; \& ENGINE_load_builtin_engines(); \& e = ENGINE_by_id(engine_id); \& if (!e) \& /* the engine isn\*(Aqt available */ \& return; \& if (!ENGINE_init(e)) { \& /* the engine couldn\*(Aqt initialise, release \*(Aqe\*(Aq */ \& ENGINE_free(e); \& return; \& } \& if (!ENGINE_set_default_RSA(e)) \& /* \& * This should only happen when \*(Aqe\*(Aq can\*(Aqt initialise, but the previous \& * statement suggests it did. \& */ \& abort(); \& ENGINE_set_default_DSA(e); \& ENGINE_set_default_ciphers(e); \& /* Release the functional reference from ENGINE_init() */ \& ENGINE_finish(e); \& /* Release the structural reference from ENGINE_by_id() */ \& ENGINE_free(e); .Ve .PP \&\fIAutomatically using builtin \s-1ENGINE\s0 implementations\fR .PP Here we'll assume we want to load and register all \s-1ENGINE\s0 implementations bundled with OpenSSL, such that for any cryptographic algorithm required by OpenSSL \- if there is an \s-1ENGINE\s0 that implements it and can be initialised, it should be used. The following code illustrates how this can work; .PP .Vb 4 \& /* Load all bundled ENGINEs into memory and make them visible */ \& ENGINE_load_builtin_engines(); \& /* Register all of them for every algorithm they collectively implement */ \& ENGINE_register_all_complete(); .Ve .PP That's all that's required. Eg. the next time OpenSSL tries to set up an \&\s-1RSA\s0 key, any bundled ENGINEs that implement \s-1RSA_METHOD\s0 will be passed to \&\fBENGINE_init()\fR and if any of those succeed, that \s-1ENGINE\s0 will be set as the default for \s-1RSA\s0 use from then on. .SS "Advanced configuration support" .IX Subsection "Advanced configuration support" There is a mechanism supported by the \s-1ENGINE\s0 framework that allows each \&\s-1ENGINE\s0 implementation to define an arbitrary set of configuration \&\*(L"commands\*(R" and expose them to OpenSSL and any applications based on OpenSSL. This mechanism is entirely based on the use of name-value pairs and assumes \s-1ASCII\s0 input (no unicode or \s-1UTF\s0 for now!), so it is ideal if applications want to provide a transparent way for users to provide arbitrary configuration \*(L"directives\*(R" directly to such ENGINEs. It is also possible for the application to dynamically interrogate the loaded \s-1ENGINE\s0 implementations for the names, descriptions, and input flags of their available \*(L"control commands\*(R", providing a more flexible configuration scheme. However, if the user is expected to know which \s-1ENGINE\s0 device he/she is using (in the case of specialised hardware, this goes without saying) then applications may not need to concern themselves with discovering the supported control commands and simply prefer to pass settings into ENGINEs exactly as they are provided by the user. .PP Before illustrating how control commands work, it is worth mentioning what they are typically used for. Broadly speaking there are two uses for control commands; the first is to provide the necessary details to the implementation (which may know nothing at all specific to the host system) so that it can be initialised for use. This could include the path to any driver or config files it needs to load, required network addresses, smart-card identifiers, passwords to initialise protected devices, logging information, etc etc. This class of commands typically needs to be passed to an \s-1ENGINE\s0 \fBbefore\fR attempting to initialise it, i.e. before calling \fBENGINE_init()\fR. The other class of commands consist of settings or operations that tweak certain behaviour or cause certain operations to take place, and these commands may work either before or after \fBENGINE_init()\fR, or in some cases both. \s-1ENGINE\s0 implementations should provide indications of this in the descriptions attached to builtin control commands and/or in external product documentation. .PP \&\fIIssuing control commands to an \s-1ENGINE\s0\fR .PP Let's illustrate by example; a function for which the caller supplies the name of the \s-1ENGINE\s0 it wishes to use, a table of string-pairs for use before initialisation, and another table for use after initialisation. Note that the string-pairs used for control commands consist of a command \*(L"name\*(R" followed by the command \*(L"parameter\*(R" \- the parameter could be \s-1NULL\s0 in some cases but the name can not. This function should initialise the \s-1ENGINE\s0 (issuing the \*(L"pre\*(R" commands beforehand and the \*(L"post\*(R" commands afterwards) and set it as the default for everything except \s-1RAND\s0 and then return a boolean success or failure. .PP .Vb 10 \& int generic_load_engine_fn(const char *engine_id, \& const char **pre_cmds, int pre_num, \& const char **post_cmds, int post_num) \& { \& ENGINE *e = ENGINE_by_id(engine_id); \& if (!e) return 0; \& while (pre_num\-\-) { \& if (!ENGINE_ctrl_cmd_string(e, pre_cmds[0], pre_cmds[1], 0)) { \& fprintf(stderr, "Failed command (%s \- %s:%s)\en", engine_id, \& pre_cmds[0], pre_cmds[1] ? pre_cmds[1] : "(NULL)"); \& ENGINE_free(e); \& return 0; \& } \& pre_cmds += 2; \& } \& if (!ENGINE_init(e)) { \& fprintf(stderr, "Failed initialisation\en"); \& ENGINE_free(e); \& return 0; \& } \& /* \& * ENGINE_init() returned a functional reference, so free the structural \& * reference from ENGINE_by_id(). \& */ \& ENGINE_free(e); \& while (post_num\-\-) { \& if (!ENGINE_ctrl_cmd_string(e, post_cmds[0], post_cmds[1], 0)) { \& fprintf(stderr, "Failed command (%s \- %s:%s)\en", engine_id, \& post_cmds[0], post_cmds[1] ? post_cmds[1] : "(NULL)"); \& ENGINE_finish(e); \& return 0; \& } \& post_cmds += 2; \& } \& ENGINE_set_default(e, ENGINE_METHOD_ALL & ~ENGINE_METHOD_RAND); \& /* Success */ \& return 1; \& } .Ve .PP Note that \fBENGINE_ctrl_cmd_string()\fR accepts a boolean argument that can relax the semantics of the function \- if set nonzero it will only return failure if the \s-1ENGINE\s0 supported the given command name but failed while executing it, if the \s-1ENGINE\s0 doesn't support the command name it will simply return success without doing anything. In this case we assume the user is only supplying commands specific to the given \s-1ENGINE\s0 so we set this to \&\s-1FALSE.\s0 .PP \&\fIDiscovering supported control commands\fR .PP It is possible to discover at run-time the names, numerical-ids, descriptions and input parameters of the control commands supported by an \s-1ENGINE\s0 using a structural reference. Note that some control commands are defined by OpenSSL itself and it will intercept and handle these control commands on behalf of the \&\s-1ENGINE,\s0 i.e. the \s-1ENGINE\s0's \fBctrl()\fR handler is not used for the control command. openssl/engine.h defines an index, \s-1ENGINE_CMD_BASE,\s0 that all control commands implemented by ENGINEs should be numbered from. Any command value lower than this symbol is considered a \*(L"generic\*(R" command is handled directly by the OpenSSL core routines. .PP It is using these \*(L"core\*(R" control commands that one can discover the control commands implemented by a given \s-1ENGINE,\s0 specifically the commands: .PP .Vb 9 \& ENGINE_HAS_CTRL_FUNCTION \& ENGINE_CTRL_GET_FIRST_CMD_TYPE \& ENGINE_CTRL_GET_NEXT_CMD_TYPE \& ENGINE_CTRL_GET_CMD_FROM_NAME \& ENGINE_CTRL_GET_NAME_LEN_FROM_CMD \& ENGINE_CTRL_GET_NAME_FROM_CMD \& ENGINE_CTRL_GET_DESC_LEN_FROM_CMD \& ENGINE_CTRL_GET_DESC_FROM_CMD \& ENGINE_CTRL_GET_CMD_FLAGS .Ve .PP Whilst these commands are automatically processed by the OpenSSL framework code, they use various properties exposed by each \s-1ENGINE\s0 to process these queries. An \s-1ENGINE\s0 has 3 properties it exposes that can affect how this behaves; it can supply a \fBctrl()\fR handler, it can specify \s-1ENGINE_FLAGS_MANUAL_CMD_CTRL\s0 in the \s-1ENGINE\s0's flags, and it can expose an array of control command descriptions. If an \s-1ENGINE\s0 specifies the \s-1ENGINE_FLAGS_MANUAL_CMD_CTRL\s0 flag, then it will simply pass all these \*(L"core\*(R" control commands directly to the \s-1ENGINE\s0's \fBctrl()\fR handler (and thus, it must have supplied one), so it is up to the \s-1ENGINE\s0 to reply to these \*(L"discovery\*(R" commands itself. If that flag is not set, then the OpenSSL framework code will work with the following rules: .PP .Vb 9 \& if no ctrl() handler supplied; \& ENGINE_HAS_CTRL_FUNCTION returns FALSE (zero), \& all other commands fail. \& if a ctrl() handler was supplied but no array of control commands; \& ENGINE_HAS_CTRL_FUNCTION returns TRUE, \& all other commands fail. \& if a ctrl() handler and array of control commands was supplied; \& ENGINE_HAS_CTRL_FUNCTION returns TRUE, \& all other commands proceed processing ... .Ve .PP If the \s-1ENGINE\s0's array of control commands is empty then all other commands will fail, otherwise; \s-1ENGINE_CTRL_GET_FIRST_CMD_TYPE\s0 returns the identifier of the first command supported by the \s-1ENGINE, ENGINE_GET_NEXT_CMD_TYPE\s0 takes the identifier of a command supported by the \s-1ENGINE\s0 and returns the next command identifier or fails if there are no more, \s-1ENGINE_CMD_FROM_NAME\s0 takes a string name for a command and returns the corresponding identifier or fails if no such command name exists, and the remaining commands take a command identifier and return properties of the corresponding commands. All except \&\s-1ENGINE_CTRL_GET_FLAGS\s0 return the string length of a command name or description, or populate a supplied character buffer with a copy of the command name or description. \s-1ENGINE_CTRL_GET_FLAGS\s0 returns a bitwise-OR'd mask of the following possible values: .PP .Vb 4 \& ENGINE_CMD_FLAG_NUMERIC \& ENGINE_CMD_FLAG_STRING \& ENGINE_CMD_FLAG_NO_INPUT \& ENGINE_CMD_FLAG_INTERNAL .Ve .PP If the \s-1ENGINE_CMD_FLAG_INTERNAL\s0 flag is set, then any other flags are purely informational to the caller \- this flag will prevent the command being usable for any higher-level \s-1ENGINE\s0 functions such as \fBENGINE_ctrl_cmd_string()\fR. \&\*(L"\s-1INTERNAL\*(R"\s0 commands are not intended to be exposed to text-based configuration by applications, administrations, users, etc. These can support arbitrary operations via \fBENGINE_ctrl()\fR, including passing to and/or from the control commands data of any arbitrary type. These commands are supported in the discovery mechanisms simply to allow applications to determine if an \s-1ENGINE\s0 supports certain specific commands it might want to use (e.g. application \*(L"foo\*(R" might query various ENGINEs to see if they implement \*(L"\s-1FOO_GET_VENDOR_LOGO_GIF\*(R"\s0 \- and \s-1ENGINE\s0 could therefore decide whether or not to support this \*(L"foo\*(R"\-specific extension). .SH "ENVIRONMENT" .IX Header "ENVIRONMENT" .IP "\fB\s-1OPENSSL_ENGINES\s0\fR" 4 .IX Item "OPENSSL_ENGINES" The path to the engines directory.

The information is passed to \s-1SSL\s0 objects \fBssl\fR created from \fBctx\fR with \fBSSL_new\fR\|(3) by copying, so that changes applied to \fBctx\fR do not propagate to already existing \s-1SSL\s0 objects. .PP The SSL_* class of functions only loads certificates and keys into a specific \s-1SSL\s0 object. The specific information is kept, when \&\fBSSL_clear\fR\|(3) is called for this \s-1SSL\s0 object. .PP \&\fBSSL_CTX_use_certificate()\fR loads the certificate \fBx\fR into \fBctx\fR, \&\fBSSL_use_certificate()\fR loads \fBx\fR into \fBssl\fR. The rest of the certificates needed to form the complete certificate chain can be specified using the \&\fBSSL_CTX_add_extra_chain_cert\fR\|(3) function. .PP \&\fBSSL_CTX_use_certificate_ASN1()\fR loads the \s-1ASN1\s0 encoded certificate from the memory location \fBd\fR (with length \fBlen\fR) into \fBctx\fR, \&\fBSSL_use_certificate_ASN1()\fR loads the \s-1ASN1\s0 encoded certificate into \fBssl\fR. .PP \&\fBSSL_CTX_use_certificate_file()\fR loads the first certificate stored in \fBfile\fR into \fBctx\fR. The formatting \fBtype\fR of the certificate must be specified from the known types \s-1SSL_FILETYPE_PEM, SSL_FILETYPE_ASN1.\s0 \&\fBSSL_use_certificate_file()\fR loads the certificate from \fBfile\fR into \fBssl\fR. See the \s-1NOTES\s0 section on why \fBSSL_CTX_use_certificate_chain_file()\fR should be preferred. .PP \&\fBSSL_CTX_use_certificate_chain_file()\fR loads a certificate chain from \&\fBfile\fR into \fBctx\fR. The certificates must be in \s-1PEM\s0 format and must be sorted starting with the subject's certificate (actual client or server certificate), followed by intermediate \s-1CA\s0 certificates if applicable, and ending at the highest level (root) \s-1CA.\s0 \fBSSL_use_certificate_chain_file()\fR is similar except it loads the certificate chain into \fBssl\fR. .PP \&\fBSSL_CTX_use_PrivateKey()\fR adds \fBpkey\fR as private key to \fBctx\fR. \&\fBSSL_CTX_use_RSAPrivateKey()\fR adds the private key \fBrsa\fR of type \s-1RSA\s0 to \fBctx\fR. \fBSSL_use_PrivateKey()\fR adds \fBpkey\fR as private key to \fBssl\fR; \&\fBSSL_use_RSAPrivateKey()\fR adds \fBrsa\fR as private key of type \s-1RSA\s0 to \fBssl\fR. If a certificate has already been set and the private does not belong to the certificate an error is returned. To change a certificate, private key pair the new certificate needs to be set with \fBSSL_use_certificate()\fR or \fBSSL_CTX_use_certificate()\fR before setting the private key with \&\fBSSL_CTX_use_PrivateKey()\fR or \fBSSL_use_PrivateKey()\fR. .PP \&\fBSSL_CTX_use_cert_and_key()\fR and \fBSSL_use_cert_and_key()\fR assign the X.509 certificate \fBx\fR, private key \fBkey\fR, and certificate \fBchain\fR onto the corresponding \fBssl\fR or \fBctx\fR. The \fBpkey\fR argument must be the private key of the X.509 certificate \fBx\fR. If the \fBoverride\fR argument is 0, then \&\fBx\fR, \fBpkey\fR and \fBchain\fR are set only if all were not previously set. If \fBoverride\fR is non\-0, then the certificate, private key and chain certs are always set. If \fBpkey\fR is \s-1NULL,\s0 then the public key of \fBx\fR is used as the private key. This is intended to be used with hardware (via the \s-1ENGINE\s0 interface) that stores the private key securely, such that it cannot be accessed by OpenSSL. The reference count of the public key is incremented (twice if there is no private key); it is not copied nor duplicated. This allows all private key validations checks to succeed without an actual private key being assigned via \fBSSL_CTX_use_PrivateKey()\fR, etc. .PP \&\fBSSL_CTX_use_PrivateKey_ASN1()\fR adds the private key of type \fBpk\fR stored at memory location \fBd\fR (length \fBlen\fR) to \fBctx\fR. \&\fBSSL_CTX_use_RSAPrivateKey_ASN1()\fR adds the private key of type \s-1RSA\s0 stored at memory location \fBd\fR (length \fBlen\fR) to \fBctx\fR. \&\fBSSL_use_PrivateKey_ASN1()\fR and \fBSSL_use_RSAPrivateKey_ASN1()\fR add the private key to \fBssl\fR. .PP \&\fBSSL_CTX_use_PrivateKey_file()\fR adds the first private key found in \&\fBfile\fR to \fBctx\fR. The formatting \fBtype\fR of the private key must be specified from the known types \s-1SSL_FILETYPE_PEM, SSL_FILETYPE_ASN1.\s0 \&\fBSSL_CTX_use_RSAPrivateKey_file()\fR adds the first private \s-1RSA\s0 key found in \&\fBfile\fR to \fBctx\fR. \fBSSL_use_PrivateKey_file()\fR adds the first private key found in \fBfile\fR to \fBssl\fR; \fBSSL_use_RSAPrivateKey_file()\fR adds the first private \&\s-1RSA\s0 key found to \fBssl\fR. .PP \&\fBSSL_CTX_check_private_key()\fR checks the consistency of a private key with the corresponding certificate loaded into \fBctx\fR. If more than one key/certificate pair (\s-1RSA/DSA\s0) is installed, the last item installed will be checked. If e.g. the last item was a \s-1RSA\s0 certificate or key, the \s-1RSA\s0 key/certificate pair will be checked. \fBSSL_check_private_key()\fR performs the same check for \fBssl\fR. If no key/certificate was explicitly added for this \fBssl\fR, the last item added into \fBctx\fR will be checked. .SH "NOTES" .IX Header "NOTES" The internal certificate store of OpenSSL can hold several private key/certificate pairs at a time. The certificate used depends on the cipher selected, see also \fBSSL_CTX_set_cipher_list\fR\|(3). .PP When reading certificates and private keys from file, files of type \&\s-1SSL_FILETYPE_ASN1\s0 (also known as \fB\s-1DER\s0\fR, binary encoding) can only contain one certificate or private key, consequently \&\fBSSL_CTX_use_certificate_chain_file()\fR is only applicable to \s-1PEM\s0 formatting. Files of type \s-1SSL_FILETYPE_PEM\s0 can contain more than one item. .PP \&\fBSSL_CTX_use_certificate_chain_file()\fR adds the first certificate found in the file to the certificate store. The other certificates are added to the store of chain certificates using \fBSSL_CTX_add1_chain_cert\fR\|(3). Note: versions of OpenSSL before 1.0.2 only had a single certificate chain store for all certificate types, OpenSSL 1.0.2 and later have a separate chain store for each type. \fBSSL_CTX_use_certificate_chain_file()\fR should be used instead of the \fBSSL_CTX_use_certificate_file()\fR function in order to allow the use of complete certificate chains even when no trusted \s-1CA\s0 storage is used or when the \s-1CA\s0 issuing the certificate shall not be added to the trusted \s-1CA\s0 storage. .PP If additional certificates are needed to complete the chain during the \&\s-1TLS\s0 negotiation, \s-1CA\s0 certificates are additionally looked up in the locations of trusted \s-1CA\s0 certificates, see \&\fBSSL_CTX_load_verify_locations\fR\|(3). .PP The private keys loaded from file can be encrypted. In order to successfully load encrypted keys, a function returning the passphrase must have been supplied, see \&\fBSSL_CTX_set_default_passwd_cb\fR\|(3). (Certificate files might be encrypted as well from the technical point of view, it however does not make sense as the data in the certificate is considered public anyway.) .PP All of the functions to set a new certificate will replace any existing certificate of the same type that has already been set. Similarly all of the functions to set a new private key will replace any private key that has already been set. Applications should call \fBSSL_CTX_check_private_key\fR\|(3) or \&\fBSSL_check_private_key\fR\|(3) as appropriate after loading a new certificate and private key to confirm that the certificate and key match. .SH "RETURN VALUES" .IX Header "RETURN VALUES" On success, the functions return 1.

Base 64 encoding converts binary data into a printable form that uses the characters A\-Z, a\-z, 0\-9, \*(L"+\*(R" and \*(L"/\*(R" to represent the data. For every 3 bytes of binary data provided 4 bytes of base 64 encoded data will be produced plus some occasional newlines (see below). If the input data length is not a multiple of 3 then the output data will be padded at the end using the \*(L"=\*(R" character. .PP \&\fBEVP_ENCODE_CTX_new()\fR allocates, initializes and returns a context to be used for the encode/decode functions. .PP \&\fBEVP_ENCODE_CTX_free()\fR cleans up an encode/decode context \fBctx\fR and frees up the space allocated to it. .PP Encoding of binary data is performed in blocks of 48 input bytes (or less for the final block). For each 48 byte input block encoded 64 bytes of base 64 data is output plus an additional newline character (i.e. 65 bytes in total). The final block (which may be less than 48 bytes) will output 4 bytes for every 3 bytes of input. If the data length is not divisible by 3 then a full 4 bytes is still output for the final 1 or 2 bytes of input. Similarly a newline character will also be output. .PP \&\fBEVP_EncodeInit()\fR initialises \fBctx\fR for the start of a new encoding operation. .PP \&\fBEVP_EncodeUpdate()\fR encode \fBinl\fR bytes of data found in the buffer pointed to by \&\fBin\fR. The output is stored in the buffer \fBout\fR and the number of bytes output is stored in \fB*outl\fR. It is the caller's responsibility to ensure that the buffer at \fBout\fR is sufficiently large to accommodate the output data. Only full blocks of data (48 bytes) will be immediately processed and output by this function. Any remainder is held in the \fBctx\fR object and will be processed by a subsequent call to \fBEVP_EncodeUpdate()\fR or \fBEVP_EncodeFinal()\fR. To calculate the required size of the output buffer add together the value of \fBinl\fR with the amount of unprocessed data held in \fBctx\fR and divide the result by 48 (ignore any remainder). This gives the number of blocks of data that will be processed. Ensure the output buffer contains 65 bytes of storage for each block, plus an additional byte for a \s-1NUL\s0 terminator. \fBEVP_EncodeUpdate()\fR may be called repeatedly to process large amounts of input data. In the event of an error \&\fBEVP_EncodeUpdate()\fR will set \fB*outl\fR to 0 and return 0. On success 1 will be returned. .PP \&\fBEVP_EncodeFinal()\fR must be called at the end of an encoding operation. It will process any partial block of data remaining in the \fBctx\fR object. The output data will be stored in \fBout\fR and the length of the data written will be stored in \fB*outl\fR. It is the caller's responsibility to ensure that \fBout\fR is sufficiently large to accommodate the output data which will never be more than 65 bytes plus an additional \s-1NUL\s0 terminator (i.e. 66 bytes in total). .PP \&\fBEVP_ENCODE_CTX_copy()\fR can be used to copy a context \fBsctx\fR to a context \&\fBdctx\fR. \fBdctx\fR must be initialized before calling this function. .PP \&\fBEVP_ENCODE_CTX_num()\fR will return the number of as yet unprocessed bytes still to be encoded or decoded that are pending in the \fBctx\fR object. .PP \&\fBEVP_EncodeBlock()\fR encodes a full block of input data in \fBf\fR and of length \&\fBn\fR and stores it in \fBt\fR. For every 3 bytes of input provided 4 bytes of output data will be produced. If \fBn\fR is not divisible by 3 then the block is encoded as a final block of data and the output is padded such that it is always divisible by 4. Additionally a \s-1NUL\s0 terminator character will be added. For example if 16 bytes of input data is provided then 24 bytes of encoded data is created plus 1 byte for a \s-1NUL\s0 terminator (i.e. 25 bytes in total). The length of the data generated \fIwithout\fR the \s-1NUL\s0 terminator is returned from the function. .PP \&\fBEVP_DecodeInit()\fR initialises \fBctx\fR for the start of a new decoding operation. .PP \&\fBEVP_DecodeUpdate()\fR decodes \fBinl\fR characters of data found in the buffer pointed to by \fBin\fR. The output is stored in the buffer \fBout\fR and the number of bytes output is stored in \fB*outl\fR. It is the caller's responsibility to ensure that the buffer at \fBout\fR is sufficiently large to accommodate the output data. This function will attempt to decode as much data as possible in 4 byte chunks. Any whitespace, newline or carriage return characters are ignored. Any partial chunk of unprocessed data (1, 2 or 3 bytes) that remains at the end will be held in the \fBctx\fR object and processed by a subsequent call to \fBEVP_DecodeUpdate()\fR. If any illegal base 64 characters are encountered or if the base 64 padding character \*(L"=\*(R" is encountered in the middle of the data then the function returns \&\-1 to indicate an error. A return value of 0 or 1 indicates successful processing of the data. A return value of 0 additionally indicates that the last input data characters processed included the base 64 padding character \*(L"=\*(R" and therefore no more non-padding character data is expected to be processed. For every 4 valid base 64 bytes processed (ignoring whitespace, carriage returns and line feeds), 3 bytes of binary output data will be produced (or less at the end of the data where the padding character \*(L"=\*(R" has been used). .PP \&\fBEVP_DecodeFinal()\fR must be called at the end of a decoding operation. If there is any unprocessed data still in \fBctx\fR then the input data must not have been a multiple of 4 and therefore an error has occurred. The function will return \-1 in this case. Otherwise the function returns 1 on success. .PP \&\fBEVP_DecodeBlock()\fR will decode the block of \fBn\fR characters of base 64 data contained in \fBf\fR and store the result in \fBt\fR. Any leading whitespace will be trimmed as will any trailing whitespace, newlines, carriage returns or \s-1EOF\s0 characters. After such trimming the length of the data in \fBf\fR must be divisible by 4. For every 4 input bytes exactly 3 output bytes will be produced. The output will be padded with 0 bits if necessary to ensure that the output is always 3 bytes for every 4 input bytes. This function will return the length of the data decoded or \-1 on error. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_ENCODE_CTX_new()\fR returns a pointer to the newly allocated \s-1EVP_ENCODE_CTX\s0 object or \s-1NULL\s0 on error. .PP \&\fBEVP_ENCODE_CTX_num()\fR returns the number of bytes pending encoding or decoding in \&\fBctx\fR. .PP \&\fBEVP_EncodeUpdate()\fR returns 0 on error or 1 on success. .PP \&\fBEVP_EncodeBlock()\fR returns the number of bytes encoded excluding the \s-1NUL\s0 terminator. .PP \&\fBEVP_DecodeUpdate()\fR returns \-1 on error and 0 or 1 on success. If 0 is returned then no more non-padding base 64 characters are expected. .PP \&\fBEVP_DecodeFinal()\fR returns \-1 on error or 1 on success. .PP \&\fBEVP_DecodeBlock()\fR returns the length of the data decoded or \-1 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBevp\fR\|(7) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2020 The OpenSSL Project Authors.

It will use the short name (e.g. \s-1CN\s0) the long name (e.g. commonName) always use \s-1OID\s0 numerical form (normally OIDs are only used if the field name is not recognised) and no field name respectively. .PP If \fB\s-1XN_FLAG_SPC_EQ\s0\fR is set then spaces will be placed around the '=' character separating field names and values. .PP If \fB\s-1XN_FLAG_DUMP_UNKNOWN_FIELDS\s0\fR is set then the encoding of unknown fields is printed instead of the values. .PP If \fB\s-1XN_FLAG_FN_ALIGN\s0\fR is set then field names are padded to 20 characters: this is only of use for multiline format. .PP Additionally all the options supported by \fBASN1_STRING_print_ex()\fR can be used to control how each field value is displayed. .PP In addition a number options can be set for commonly used formats. .PP \&\fB\s-1XN_FLAG_RFC2253\s0\fR sets options which produce an output compatible with \s-1RFC2253\s0 it is equivalent to: \fB\s-1ASN1_STRFLGS_RFC2253\s0 | \s-1XN_FLAG_SEP_COMMA_PLUS\s0 | \s-1XN_FLAG_DN_REV\s0 | \s-1XN_FLAG_FN_SN\s0 | \s-1XN_FLAG_DUMP_UNKNOWN_FIELDS\s0\fR .PP \&\fB\s-1XN_FLAG_ONELINE\s0\fR is a more readable one line format which is the same as: \fB\s-1ASN1_STRFLGS_RFC2253\s0 | \s-1ASN1_STRFLGS_ESC_QUOTE\s0 | \s-1XN_FLAG_SEP_CPLUS_SPC\s0 | \s-1XN_FLAG_SPC_EQ\s0 | \s-1XN_FLAG_FN_SN\s0\fR .PP \&\fB\s-1XN_FLAG_MULTILINE\s0\fR is a multiline format which is the same as: \fB\s-1ASN1_STRFLGS_ESC_CTRL\s0 | \s-1ASN1_STRFLGS_ESC_MSB\s0 | \s-1XN_FLAG_SEP_MULTILINE\s0 | \s-1XN_FLAG_SPC_EQ\s0 | \s-1XN_FLAG_FN_LN\s0 | \s-1XN_FLAG_FN_ALIGN\s0\fR .PP \&\fB\s-1XN_FLAG_COMPAT\s0\fR uses a format identical to \fBX509_NAME_print()\fR: in fact it calls \fBX509_NAME_print()\fR internally. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBX509_NAME_oneline()\fR returns a valid string on success or \s-1NULL\s0 on error. .PP \&\fBX509_NAME_print()\fR returns 1 on success or 0 on error. .PP \&\fBX509_NAME_print_ex()\fR and \fBX509_NAME_print_ex_fp()\fR return 1 on success or 0 on error if the \fB\s-1XN_FLAG_COMPAT\s0\fR is set, which is the same as \fBX509_NAME_print()\fR. Otherwise, it returns \-1 on error or other values on success. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBASN1_STRING_print_ex\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2002\-2018 The OpenSSL Project Authors.

Early data can be sent by the client immediately after its initial ClientHello without having to wait for the server to complete the handshake. Early data can be sent if a session has previously been established with the server or when establishing a new session using an out-of-band \s-1PSK,\s0 and only when the server is known to support it. Additionally these functions can be used to send data from the server to the client when the client has not yet completed the authentication stage of the handshake. .PP Early data has weaker security properties than other data sent over an \s-1SSL/TLS\s0 connection. In particular the data does not have forward secrecy. There are also additional considerations around replay attacks (see \*(L"\s-1REPLAY PROTECTION\*(R"\s0 below). For these reasons extreme care should be exercised when using early data. For specific details, consult the \s-1TLS 1.3\s0 specification. .PP When a server receives early data it may opt to immediately respond by sending application data back to the client. Data sent by the server at this stage is done before the full handshake has been completed. Specifically the client's authentication messages have not yet been received, i.e. the client is unauthenticated at this point and care should be taken when using this capability. .PP A server or client can determine whether the full handshake has been completed or not by calling \fBSSL_is_init_finished\fR\|(3). .PP On the client side, the function \fBSSL_SESSION_get_max_early_data()\fR can be used to determine if a session established with a server can be used to send early data. If the session cannot be used then this function will return 0. Otherwise it will return the maximum number of early data bytes that can be sent. .PP The function \fBSSL_SESSION_set_max_early_data()\fR sets the maximum number of early data bytes that can be sent for a session. This would typically be used when creating a \s-1PSK\s0 session file (see \fBSSL_CTX_set_psk_use_session_callback\fR\|(3)). If using a ticket based \s-1PSK\s0 then this is set automatically to the value provided by the server. .PP A client uses the function \fBSSL_write_early_data()\fR to send early data. This function is similar to the \fBSSL_write_ex\fR\|(3) function, but with the following differences. See \fBSSL_write_ex\fR\|(3) for information on how to write bytes to the underlying connection, and how to handle any errors that may arise. This page describes the differences between \fBSSL_write_early_data()\fR and \&\fBSSL_write_ex\fR\|(3). .PP When called by a client, \fBSSL_write_early_data()\fR must be the first \s-1IO\s0 function called on a new connection, i.e. it must occur before any calls to \&\fBSSL_write_ex\fR\|(3), \fBSSL_read_ex\fR\|(3), \fBSSL_connect\fR\|(3), \fBSSL_do_handshake\fR\|(3) or other similar functions. It may be called multiple times to stream data to the server, but the total number of bytes written must not exceed the value returned from \fBSSL_SESSION_get_max_early_data()\fR. Once the initial \&\fBSSL_write_early_data()\fR call has completed successfully the client may interleave calls to \fBSSL_read_ex\fR\|(3) and \fBSSL_read\fR\|(3) with calls to \&\fBSSL_write_early_data()\fR as required. .PP If \fBSSL_write_early_data()\fR fails you should call \fBSSL_get_error\fR\|(3) to determine the correct course of action, as for \fBSSL_write_ex\fR\|(3). .PP When the client no longer wishes to send any more early data then it should complete the handshake by calling a function such as \fBSSL_connect\fR\|(3) or \&\fBSSL_do_handshake\fR\|(3). Alternatively you can call a standard write function such as \fBSSL_write_ex\fR\|(3), which will transparently complete the connection and write the requested data. .PP A server may choose to ignore early data that has been sent to it. Once the connection has been completed you can determine whether the server accepted or rejected the early data by calling \fBSSL_get_early_data_status()\fR. This will return \&\s-1SSL_EARLY_DATA_ACCEPTED\s0 if the data was accepted, \s-1SSL_EARLY_DATA_REJECTED\s0 if it was rejected or \s-1SSL_EARLY_DATA_NOT_SENT\s0 if no early data was sent. This function may be called by either the client or the server. .PP A server uses the \fBSSL_read_early_data()\fR function to receive early data on a connection for which early data has been enabled using \&\fBSSL_CTX_set_max_early_data()\fR or \fBSSL_set_max_early_data()\fR. As for \&\fBSSL_write_early_data()\fR, this must be the first \s-1IO\s0 function called on a connection, i.e. it must occur before any calls to \&\fBSSL_write_ex\fR\|(3), \fBSSL_read_ex\fR\|(3), \fBSSL_accept\fR\|(3), \fBSSL_do_handshake\fR\|(3), or other similar functions. .PP \&\fBSSL_read_early_data()\fR is similar to \fBSSL_read_ex\fR\|(3) with the following differences. Refer to \fBSSL_read_ex\fR\|(3) for full details. .PP \&\fBSSL_read_early_data()\fR may return 3 possible values: .IP "\s-1SSL_READ_EARLY_DATA_ERROR\s0" 4 .IX Item "SSL_READ_EARLY_DATA_ERROR" This indicates an \s-1IO\s0 or some other error occurred. This should be treated in the same way as a 0 return value from \fBSSL_read_ex\fR\|(3). .IP "\s-1SSL_READ_EARLY_DATA_SUCCESS\s0" 4 .IX Item "SSL_READ_EARLY_DATA_SUCCESS" This indicates that early data was successfully read. This should be treated in the same way as a 1 return value from \fBSSL_read_ex\fR\|(3). You should continue to call \fBSSL_read_early_data()\fR to read more data. .IP "\s-1SSL_READ_EARLY_DATA_FINISH\s0" 4 .IX Item "SSL_READ_EARLY_DATA_FINISH" This indicates that no more early data can be read. It may be returned on the first call to \fBSSL_read_early_data()\fR if the client has not sent any early data, or if the early data was rejected. .PP Once the initial \fBSSL_read_early_data()\fR call has completed successfully (i.e. it has returned \s-1SSL_READ_EARLY_DATA_SUCCESS\s0 or \s-1SSL_READ_EARLY_DATA_FINISH\s0) then the server may choose to write data immediately to the unauthenticated client using \&\fBSSL_write_early_data()\fR. If \fBSSL_read_early_data()\fR returned \&\s-1SSL_READ_EARLY_DATA_FINISH\s0 then in some situations (e.g. if the client only supports TLSv1.2) the handshake may have already been completed and calls to \fBSSL_write_early_data()\fR are not allowed. Call \fBSSL_is_init_finished\fR\|(3) to determine whether the handshake has completed or not. If the handshake is still in progress then the server may interleave calls to \fBSSL_write_early_data()\fR with calls to \fBSSL_read_early_data()\fR as required. .PP Servers must not call \fBSSL_read_ex\fR\|(3), \fBSSL_read\fR\|(3), \fBSSL_write_ex\fR\|(3) or \&\fBSSL_write\fR\|(3) until \fBSSL_read_early_data()\fR has returned with \&\s-1SSL_READ_EARLY_DATA_FINISH.\s0 Once it has done so the connection to the client still needs to be completed. Complete the connection by calling a function such as \fBSSL_accept\fR\|(3) or \fBSSL_do_handshake\fR\|(3). Alternatively you can call a standard read function such as \fBSSL_read_ex\fR\|(3), which will transparently complete the connection and read the requested data. Note that it is an error to attempt to complete the connection before \fBSSL_read_early_data()\fR has returned \&\s-1SSL_READ_EARLY_DATA_FINISH.\s0 .PP Only servers may call \fBSSL_read_early_data()\fR. .PP Calls to \fBSSL_read_early_data()\fR may, in certain circumstances, complete the connection immediately without further need to call a function such as \&\fBSSL_accept\fR\|(3). This can happen if the client is using a protocol version less than TLSv1.3. Applications can test for this by calling \&\fBSSL_is_init_finished\fR\|(3). Alternatively, applications may choose to call \&\fBSSL_accept\fR\|(3) anyway. Such a call will successfully return immediately with no further action taken. .PP When a session is created between a server and a client the server will specify the maximum amount of any early data that it will accept on any future connection attempt. By default the server does not accept early data; a server may indicate support for early data by calling \&\fBSSL_CTX_set_max_early_data()\fR or \&\fBSSL_set_max_early_data()\fR to set it for the whole \s-1SSL_CTX\s0 or an individual \s-1SSL\s0 object respectively. The \fBmax_early_data\fR parameter specifies the maximum amount of early data in bytes that is permitted to be sent on a single connection. Similarly the \fBSSL_CTX_get_max_early_data()\fR and \&\fBSSL_get_max_early_data()\fR functions can be used to obtain the current maximum early data settings for the \s-1SSL_CTX\s0 and \s-1SSL\s0 objects respectively. Generally a server application will either use both of \fBSSL_read_early_data()\fR and \&\fBSSL_CTX_set_max_early_data()\fR (or \fBSSL_set_max_early_data()\fR), or neither of them, since there is no practical benefit from using only one of them. If the maximum early data setting for a server is nonzero then replay protection is automatically enabled (see \*(L"\s-1REPLAY PROTECTION\*(R"\s0 below). .PP If the server rejects the early data sent by a client then it will skip over the data that is sent. The maximum amount of received early data that is skipped is controlled by the recv_max_early_data setting. If a client sends more than this then the connection will abort. This value can be set by calling \&\fBSSL_CTX_set_recv_max_early_data()\fR or \fBSSL_set_recv_max_early_data()\fR. The current value for this setting can be obtained by calling \&\fBSSL_CTX_get_recv_max_early_data()\fR or \fBSSL_get_recv_max_early_data()\fR. The default value for this setting is 16,384 bytes. .PP The recv_max_early_data value also has an impact on early data that is accepted. The amount of data that is accepted will always be the lower of the max_early_data for the session and the recv_max_early_data setting for the server. If a client sends more data than this then the connection will abort. .PP The configured value for max_early_data on a server may change over time as required. However, clients may have tickets containing the previously configured max_early_data value. The recv_max_early_data should always be equal to or higher than any recently configured max_early_data value in order to avoid aborted connections. The recv_max_early_data should never be set to less than the current configured max_early_data value. .PP Some server applications may wish to have more control over whether early data is accepted or not, for example to mitigate replay risks (see \*(L"\s-1REPLAY PROTECTION\*(R"\s0 below) or to decline early_data when the server is heavily loaded. The functions \&\fBSSL_CTX_set_allow_early_data_cb()\fR and \fBSSL_set_allow_early_data_cb()\fR set a callback which is called at a point in the handshake immediately before a decision is made to accept or reject early data. The callback is provided with a pointer to the user data argument that was provided when the callback was first set. Returning 1 from the callback will allow early data and returning 0 will reject it. Note that the OpenSSL library may reject early data for other reasons in which case this callback will not get called. Notably, the built-in replay protection feature will still be used even if a callback is present unless it has been explicitly disabled using the \s-1SSL_OP_NO_ANTI_REPLAY\s0 option. See \&\*(L"\s-1REPLAY PROTECTION\*(R"\s0 below. .SH "NOTES" .IX Header "NOTES" The whole purpose of early data is to enable a client to start sending data to the server before a full round trip of network traffic has occurred. Application developers should ensure they consider optimisation of the underlying \s-1TCP\s0 socket to obtain a performant solution. For example Nagle's algorithm is commonly used by operating systems in an attempt to avoid lots of small \s-1TCP\s0 packets. In many scenarios this is beneficial for performance, but it does not work well with the early data solution as implemented in OpenSSL. In Nagle's algorithm the \s-1OS\s0 will buffer outgoing \s-1TCP\s0 data if a \s-1TCP\s0 packet has already been sent which we have not yet received an \s-1ACK\s0 for from the peer. The buffered data will only be transmitted if enough data to fill an entire \s-1TCP\s0 packet is accumulated, or if the \s-1ACK\s0 is received from the peer. The initial ClientHello will be sent in the first \s-1TCP\s0 packet along with any data from the first call to \&\fBSSL_write_early_data()\fR. If the amount of data written will exceed the size of a single \s-1TCP\s0 packet, or if there are more calls to \fBSSL_write_early_data()\fR then that additional data will be sent in subsequent \s-1TCP\s0 packets which will be buffered by the \s-1OS\s0 and not sent until an \s-1ACK\s0 is received for the first packet containing the ClientHello. This means the early data is not actually sent until a complete round trip with the server has occurred which defeats the objective of early data. .PP In many operating systems the \s-1TCP_NODELAY\s0 socket option is available to disable Nagle's algorithm. If an application opts to disable Nagle's algorithm consideration should be given to turning it back on again after the handshake is complete if appropriate. .PP In rare circumstances, it may be possible for a client to have a session that reports a max early data value greater than 0, but where the server does not support this. For example, this can occur if a server has had its configuration changed to accept a lower max early data value such as by calling \&\fBSSL_CTX_set_recv_max_early_data()\fR. Another example is if a server used to support TLSv1.3 but was later downgraded to TLSv1.2. Sending early data to such a server will cause the connection to abort. Clients that encounter an aborted connection while sending early data may want to retry the connection without sending early data as this does not happen automatically. A client will have to establish a new transport layer connection to the server and attempt the \s-1SSL/TLS\s0 connection again but without sending early data. Note that it is inadvisable to retry with a lower maximum protocol version. .SH "REPLAY PROTECTION" .IX Header "REPLAY PROTECTION" When early data is in use the \s-1TLS\s0 protocol provides no security guarantees that the same early data was not replayed across multiple connections. As a mitigation for this issue OpenSSL automatically enables replay protection if the server is configured with a nonzero max early data value. With replay protection enabled sessions are forced to be single use only. If a client attempts to reuse a session ticket more than once, then the second and subsequent attempts will fall back to a full handshake (and any early data that was submitted will be ignored). Note that single use tickets are enforced even if a client does not send any early data. .PP The replay protection mechanism relies on the internal OpenSSL server session cache (see \fBSSL_CTX_set_session_cache_mode\fR\|(3)). When replay protection is being used the server will operate as if the \s-1SSL_OP_NO_TICKET\s0 option had been selected (see \fBSSL_CTX_set_options\fR\|(3)). Sessions will be added to the cache whenever a session ticket is issued. When a client attempts to resume the session, OpenSSL will check for its presence in the internal cache. If it exists then the resumption is allowed and the session is removed from the cache. If it does not exist then the resumption is not allowed and a full handshake will occur. .PP Note that some applications may maintain an external cache of sessions (see \&\fBSSL_CTX_sess_set_new_cb\fR\|(3) and similar functions). It is the application's responsibility to ensure that any sessions in the external cache are also populated in the internal cache and that once removed from the internal cache they are similarly removed from the external cache. Failing to do this could result in an application becoming vulnerable to replay attacks. Note that OpenSSL will lock the internal cache while a session is removed but that lock is not held when the remove session callback (see \fBSSL_CTX_sess_set_remove_cb\fR\|(3)) is called. This could result in a small amount of time where the session has been removed from the internal cache but is still available in the external cache. Applications should be designed with this in mind in order to minimise the possibility of replay attacks. .PP The OpenSSL replay protection does not apply to external Pre Shared Keys (PSKs) (e.g. see \fBSSL_CTX_set_psk_find_session_callback\fR\|(3)). Therefore, extreme caution should be applied when combining external PSKs with early data. .PP Some applications may mitigate the replay risks in other ways. For those applications it is possible to turn off the built-in replay protection feature using the \fB\s-1SSL_OP_NO_ANTI_REPLAY\s0\fR option. See \fBSSL_CTX_set_options\fR\|(3) for details. Applications can also set a callback to make decisions about accepting early data or not. See \fBSSL_CTX_set_allow_early_data_cb()\fR above for details. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_write_early_data()\fR returns 1 for success or 0 for failure.

It can be used for debugging purposes to trace operations on a \s-1BIO\s0 or to modify its operation. .PP \&\fBBIO_set_callback()\fR and \fBBIO_get_callback()\fR set and retrieve the old format \s-1BIO\s0 callback. New code should not use these functions, but they are retained for backwards compatibility.

The context can then be reused with a new call to \fBX509_STORE_CTX_init()\fR. .PP \&\fBX509_STORE_CTX_free()\fR completely frees up \fBctx\fR. After this call \fBctx\fR is no longer valid. If \fBctx\fR is \s-1NULL\s0 nothing is done. .PP \&\fBX509_STORE_CTX_init()\fR sets up \fBctx\fR for a subsequent verification operation. It must be called before each call to \fBX509_verify_cert()\fR, i.e. a \fBctx\fR is only good for one call to \fBX509_verify_cert()\fR; if you want to verify a second certificate with the same \fBctx\fR then you must call \fBX509_STORE_CTX_cleanup()\fR and then \fBX509_STORE_CTX_init()\fR again before the second call to \&\fBX509_verify_cert()\fR. The trusted certificate store is set to \fBstore\fR, the end entity certificate to be verified is set to \fBx509\fR and a set of additional certificates (which will be untrusted but may be used to build the chain) in \&\fBchain\fR. Any or all of the \fBstore\fR, \fBx509\fR and \fBchain\fR parameters can be \&\fB\s-1NULL\s0\fR. .PP \&\fBX509_STORE_CTX_set0_trusted_stack()\fR sets the set of trusted certificates of \&\fBctx\fR to \fBsk\fR. This is an alternative way of specifying trusted certificates instead of using an \fBX509_STORE\fR. .PP \&\fBX509_STORE_CTX_set_cert()\fR sets the certificate to be verified in \fBctx\fR to \&\fBx\fR. .PP \&\fBX509_STORE_CTX_set0_verified_chain()\fR sets the validated chain used by \fBctx\fR to be \fBchain\fR. Ownership of the chain is transferred to \fBctx\fR and should not be free'd by the caller. \&\fBX509_STORE_CTX_get0_chain()\fR returns the internal pointer used by the \&\fBctx\fR that contains the validated chain. .PP \&\fBX509_STORE_CTX_set0_crls()\fR sets a set of CRLs to use to aid certificate verification to \fBsk\fR. These CRLs will only be used if \s-1CRL\s0 verification is enabled in the associated \fBX509_VERIFY_PARAM\fR structure. This might be used where additional \*(L"useful\*(R" CRLs are supplied as part of a protocol, for example in a PKCS#7 structure. .PP \&\fBX509_STORE_CTX_get0_param()\fR retrieves an internal pointer to the verification parameters associated with \fBctx\fR. .PP \&\fBX509_STORE_CTX_get0_untrusted()\fR retrieves an internal pointer to the stack of untrusted certificates associated with \fBctx\fR. .PP \&\fBX509_STORE_CTX_set0_untrusted()\fR sets the internal point to the stack of untrusted certificates associated with \fBctx\fR to \fBsk\fR. .PP \&\fBX509_STORE_CTX_set0_param()\fR sets the internal verification parameter pointer to \fBparam\fR. After this call \fBparam\fR should not be used. .PP \&\fBX509_STORE_CTX_set_default()\fR looks up and sets the default verification method to \fBname\fR. This uses the function \fBX509_VERIFY_PARAM_lookup()\fR to find an appropriate set of parameters from \fBname\fR. .PP \&\fBX509_STORE_CTX_get_num_untrusted()\fR returns the number of untrusted certificates that were used in building the chain following a call to \fBX509_verify_cert()\fR. .PP \&\fBX509_STORE_CTX_set_verify()\fR provides the capability for overriding the default verify function. This function is responsible for verifying chain signatures and expiration times. .PP A verify function is defined as an X509_STORE_CTX_verify type which has the following signature: .PP .Vb 1 \& int (*verify)(X509_STORE_CTX *); .Ve .PP This function should receive the current X509_STORE_CTX as a parameter and return 1 on success or 0 on failure. .PP X509 certificates may contain information about what purposes keys contained within them can be used for. For example \*(L"\s-1TLS WWW\s0 Server Authentication\*(R" or \&\*(L"Email Protection\*(R". This \*(L"key usage\*(R" information is held internally to the certificate itself. In addition the trust store containing trusted certificates can declare what purposes we trust different certificates for. This \*(L"trust\*(R" information is not held within the certificate itself but is \*(L"meta\*(R" information held alongside it. This \*(L"meta\*(R" information is associated with the certificate after it is issued and could be determined by a system administrator. For example a certificate might declare that it is suitable for use for both \&\*(L"\s-1TLS WWW\s0 Server Authentication\*(R" and \*(L"\s-1TLS\s0 Client Authentication\*(R", but a system administrator might only trust it for the former. An X.509 certificate extension exists that can record extended key usage information to supplement the purpose information described above. This extended mechanism is arbitrarily extensible and not well suited for a generic library \s-1API\s0; applications that need to validate extended key usage information in certifiates will need to define a custom \*(L"purpose\*(R" (see below) or supply a nondefault verification callback (\fBX509_STORE_set_verify_cb_func\fR\|(3)). .PP \&\fBX509_STORE_CTX_set_purpose()\fR sets the purpose for the target certificate being verified in the \fIctx\fR. Built-in available values for the \fIpurpose\fR argument are \fBX509_PURPOSE_SSL_CLIENT\fR, \fBX509_PURPOSE_SSL_SERVER\fR, \&\fBX509_PURPOSE_NS_SSL_SERVER\fR, \fBX509_PURPOSE_SMIME_SIGN\fR, \&\fBX509_PURPOSE_SMIME_ENCRYPT\fR, \fBX509_PURPOSE_CRL_SIGN\fR, \fBX509_PURPOSE_ANY\fR, \&\fBX509_PURPOSE_OCSP_HELPER\fR and \fBX509_PURPOSE_TIMESTAMP_SIGN\fR. It is also possible to create a custom purpose value. Setting a purpose will ensure that the key usage declared within certificates in the chain being verified is consistent with that purpose as well as, potentially, other checks. Every purpose also has an associated default trust value which will also be set at the same time. During verification this trust setting will be verified to check it is consistent with the trust set by the system administrator for certificates in the chain. .PP \&\fBX509_STORE_CTX_set_trust()\fR sets the trust value for the target certificate being verified in the \fIctx\fR. Built-in available values for the \fItrust\fR argument are \fBX509_TRUST_COMPAT\fR, \fBX509_TRUST_SSL_CLIENT\fR, \&\fBX509_TRUST_SSL_SERVER\fR, \fBX509_TRUST_EMAIL\fR, \fBX509_TRUST_OBJECT_SIGN\fR, \&\fBX509_TRUST_OCSP_SIGN\fR, \fBX509_TRUST_OCSP_REQUEST\fR and \fBX509_TRUST_TSA\fR. It is also possible to create a custom trust value. Since \fBX509_STORE_CTX_set_purpose()\fR also sets the trust value it is normally sufficient to only call that function. If both are called then \fBX509_STORE_CTX_set_trust()\fR should be called after \&\fBX509_STORE_CTX_set_purpose()\fR since the trust setting of the last call will be used. .PP It should not normally be necessary for end user applications to call \&\fBX509_STORE_CTX_purpose_inherit()\fR directly. Typically applications should call \&\fBX509_STORE_CTX_set_purpose()\fR or \fBX509_STORE_CTX_set_trust()\fR instead. Using this function it is possible to set the purpose and trust values for the \fIctx\fR at the same time. Both \fIctx\fR and its internal verification parameter pointer must not be \s-1NULL.\s0 The \fIdef_purpose\fR and \fIpurpose\fR arguments can have the same purpose values as described for \fBX509_STORE_CTX_set_purpose()\fR above. The \fItrust\fR argument can have the same trust values as described in \&\fBX509_STORE_CTX_set_trust()\fR above. Any of the \fIdef_purpose\fR, \fIpurpose\fR or \&\fItrust\fR values may also have the value 0 to indicate that the supplied parameter should be ignored. After calling this function the purpose to be used for verification is set from the \fIpurpose\fR argument unless the purpose was already set in \fIctx\fR before, and the trust is set from the \fItrust\fR argument unless the trust was already set in \fIctx\fR before. If \fItrust\fR is 0 then the trust value will be set from the default trust value for \fIpurpose\fR. If the default trust value for the purpose is \fIX509_TRUST_DEFAULT\fR and \fItrust\fR is 0 then the default trust value associated with the \fIdef_purpose\fR value is used for the trust setting instead. .SH "NOTES" .IX Header "NOTES" The certificates and CRLs in a store are used internally and should \fBnot\fR be freed up until after the associated \fBX509_STORE_CTX\fR is freed. .SH "BUGS" .IX Header "BUGS" The certificates and CRLs in a context are used internally and should \fBnot\fR be freed up until after the associated \fBX509_STORE_CTX\fR is freed.

If \fBtype\fR corresponds to a primitive type (or a string type) then the contents of the \s-1ASN1_STRING\s0 contain the content octets of the type. If \fBtype\fR corresponds to a constructed type or a tagged type (V_ASN1_SEQUENCE, V_ASN1_SET or V_ASN1_OTHER) then the \&\s-1ASN1_STRING\s0 contains the entire \s-1ASN.1\s0 encoding verbatim (including tag and length octets). .PP \&\fBASN1_TYPE_cmp()\fR may not return zero if two types are equivalent but have different encodings. For example the single content octet of the boolean \s-1TRUE\s0 value under \s-1BER\s0 can have any nonzero encoding but \fBASN1_TYPE_cmp()\fR will only return zero if the values are the same. .PP If either or both of the parameters passed to \fBASN1_TYPE_cmp()\fR is \s-1NULL\s0 the return value is nonzero. Technically if both parameters are \s-1NULL\s0 the two types could be absent \s-1OPTIONAL\s0 fields and so should match, however, passing \&\s-1NULL\s0 values could also indicate a programming error (for example an unparsable type which returns \s-1NULL\s0) for types which do \fBnot\fR match. So applications should handle the case of two absent values separately. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBASN1_TYPE_get()\fR returns the type of the \s-1ASN1_TYPE\s0 argument. .PP \&\fBASN1_TYPE_set()\fR does not return a value. .PP \&\fBASN1_TYPE_set1()\fR returns 1 for success and 0 for failure. .PP \&\fBASN1_TYPE_cmp()\fR returns 0 if the types are identical and nonzero otherwise. .PP \&\fBASN1_TYPE_unpack_sequence()\fR returns a pointer to an \s-1ASN.1\s0 structure or \&\s-1NULL\s0 on failure. .PP \&\fBASN1_TYPE_pack_sequence()\fR return an \s-1ASN1_TYPE\s0 structure if it succeeds or \&\s-1NULL\s0 on failure. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2015\-2020 The OpenSSL Project Authors.

The default prefix for command line commands is \fB\-\fR and that is reflected below. .IP "\fB\-sigalgs\fR" 4 .IX Item "-sigalgs" This sets the supported signature algorithms for TLSv1.2 and TLSv1.3. For clients this value is used directly for the supported signature algorithms extension. For servers it is used to determine which signature algorithms to support. .Sp The \fBvalue\fR argument should be a colon separated list of signature algorithms in order of decreasing preference of the form \fBalgorithm+hash\fR or \&\fBsignature_scheme\fR. \fBalgorithm\fR is one of \fB\s-1RSA\s0\fR, \fB\s-1DSA\s0\fR or \fB\s-1ECDSA\s0\fR and \fBhash\fR is a supported algorithm \&\s-1OID\s0 short name such as \fB\s-1SHA1\s0\fR, \fB\s-1SHA224\s0\fR, \fB\s-1SHA256\s0\fR, \fB\s-1SHA384\s0\fR of \fB\s-1SHA512\s0\fR.

For clients, the groups are sent using the supported groups extension. For servers, it is used to determine which group to use. This setting affects groups used for signatures (in TLSv1.2 and earlier) and key exchange. The first group listed will also be used for the \fBkey_share\fR sent by a client in a TLSv1.3 \&\fBClientHello\fR. .Sp The \fBvalue\fR argument is a colon separated list of groups.

Only used by servers .Sp The \fBvalue\fR argument is a curve name or the special value \fBauto\fR which picks an appropriate curve based on client and server preferences. The curve can be either the \fB\s-1NIST\s0\fR name (e.g. \fBP\-256\fR) or an OpenSSL \s-1OID\s0 name (e.g. \fBprime256v1\fR). Curve names are case sensitive. .IP "\fB\-cipher\fR" 4 .IX Item "-cipher" Sets the TLSv1.2 and below ciphersuite list to \fBvalue\fR. This list will be combined with any configured TLSv1.3 ciphersuites. Note: syntax checking of \fBvalue\fR is currently not performed unless a \fB\s-1SSL\s0\fR or \fB\s-1SSL_CTX\s0\fR structure is associated with \fBcctx\fR. .IP "\fB\-ciphersuites\fR" 4 .IX Item "-ciphersuites" Sets the available ciphersuites for TLSv1.3 to value.

Set by default. .IP "\fB\-allow_no_dhe_kex\fR" 4 .IX Item "-allow_no_dhe_kex" In TLSv1.3 allow a non\-(ec)dhe based key exchange mode on resumption. This means that there will be no forward secrecy for the resumed session. .IP "\fB\-strict\fR" 4 .IX Item "-strict" enables strict mode protocol handling. Equivalent to setting \&\fB\s-1SSL_CERT_FLAG_TLS_STRICT\s0\fR. .IP "\fB\-anti_replay\fR, \fB\-no_anti_replay\fR" 4 .IX Item "-anti_replay, -no_anti_replay" Switches replay protection, on or off respectively. With replay protection on, OpenSSL will automatically detect if a session ticket has been used more than once, TLSv1.3 has been negotiated, and early data is enabled on the server. A full handshake is forced if a session ticket is used a second or subsequent time. Anti-Replay is on by default unless overridden by a configuration file and is only used by servers. Anti-replay measures are required for compliance with the TLSv1.3 specification. Some applications may be able to mitigate the replay risks in other ways and in such cases the built-in OpenSSL functionality is not required.

Only used by servers. .Sp \&\fBNoRenegotiation\fR: disables all attempts at renegotiation in TLSv1.2 and earlier, same as setting \fB\s-1SSL_OP_NO_RENEGOTIATION\s0\fR. .Sp \&\fBUnsafeLegacyRenegotiation\fR: permits the use of unsafe legacy renegotiation. Equivalent to \fB\s-1SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION\s0\fR. .Sp \&\fBUnsafeLegacyServerConnect\fR: permits the use of unsafe legacy renegotiation for OpenSSL clients only. Equivalent to \fB\s-1SSL_OP_LEGACY_SERVER_CONNECT\s0\fR. Set by default. .Sp \&\fBEncryptThenMac\fR: use encrypt-then-mac extension, enabled by default. Inverse of \fB\s-1SSL_OP_NO_ENCRYPT_THEN_MAC\s0\fR: that is, \&\fB\-EncryptThenMac\fR is the same as setting \fB\s-1SSL_OP_NO_ENCRYPT_THEN_MAC\s0\fR. .Sp \&\fBAllowNoDHEKEX\fR: In TLSv1.3 allow a non\-(ec)dhe based key exchange mode on resumption. This means that there will be no forward secrecy for the resumed session. Equivalent to \fB\s-1SSL_OP_ALLOW_NO_DHE_KEX\s0\fR. .Sp \&\fBMiddleboxCompat\fR: If set then dummy Change Cipher Spec (\s-1CCS\s0) messages are sent in TLSv1.3. This has the effect of making TLSv1.3 look more like TLSv1.2 so that middleboxes that do not understand TLSv1.3 will not drop the connection. This option is set by default. A future version of OpenSSL may not set this by default. Equivalent to \fB\s-1SSL_OP_ENABLE_MIDDLEBOX_COMPAT\s0\fR. .Sp \&\fBAntiReplay\fR: If set then OpenSSL will automatically detect if a session ticket has been used more than once, TLSv1.3 has been negotiated, and early data is enabled on the server. A full handshake is forced if a session ticket is used a second or subsequent time. This option is set by default and is only used by servers. Anti-replay measures are required to comply with the TLSv1.3 specification. Some applications may be able to mitigate the replay risks in other ways and in such cases the built-in OpenSSL functionality is not required. Disabling anti-replay is equivalent to setting \fB\s-1SSL_OP_NO_ANTI_REPLAY\s0\fR. .IP "\fBVerifyMode\fR" 4 .IX Item "VerifyMode" The \fBvalue\fR argument is a comma separated list of flags to set. .Sp \&\fBPeer\fR enables peer verification: for clients only. .Sp \&\fBRequest\fR requests but does not require a certificate from the client. Servers only. .Sp \&\fBRequire\fR requests and requires a certificate from the client: an error occurs if the client does not present a certificate. Servers only. .Sp \&\fBOnce\fR requests a certificate from a client only on the initial connection: not when renegotiating. Servers only. .Sp \&\fBRequestPostHandshake\fR configures the connection to support requests but does not require a certificate from the client post-handshake. A certificate will not be requested during the initial handshake. The server application must provide a mechanism to request a certificate post-handshake. Servers only. TLSv1.3 only. .Sp \&\fBRequiresPostHandshake\fR configures the connection to support requests and requires a certificate from the client post-handshake: an error occurs if the client does not present a certificate. A certificate will not be requested during the initial handshake. The server application must provide a mechanism to request a certificate post-handshake. Servers only. TLSv1.3 only. .IP "\fBClientCAFile\fR, \fBClientCAPath\fR" 4 .IX Item "ClientCAFile, ClientCAPath" A file or directory of certificates in \s-1PEM\s0 format whose names are used as the set of acceptable names for client CAs. Servers only. This option is only supported if certificate operations are permitted. .SH "SUPPORTED COMMAND TYPES" .IX Header "SUPPORTED COMMAND TYPES" The function \fBSSL_CONF_cmd_value_type()\fR currently returns one of the following types: .IP "\fB\s-1SSL_CONF_TYPE_UNKNOWN\s0\fR" 4 .IX Item "SSL_CONF_TYPE_UNKNOWN" The \fBcmd\fR string is unrecognised, this return value can be use to flag syntax errors. .IP "\fB\s-1SSL_CONF_TYPE_STRING\s0\fR" 4 .IX Item "SSL_CONF_TYPE_STRING" The value is a string without any specific structure. .IP "\fB\s-1SSL_CONF_TYPE_FILE\s0\fR" 4 .IX Item "SSL_CONF_TYPE_FILE" The value is a filename. .IP "\fB\s-1SSL_CONF_TYPE_DIR\s0\fR" 4 .IX Item "SSL_CONF_TYPE_DIR" The value is a directory name. .IP "\fB\s-1SSL_CONF_TYPE_NONE\s0\fR" 4 .IX Item "SSL_CONF_TYPE_NONE" The value string is not used e.g. a command line option which doesn't take an argument. .SH "NOTES" .IX Header "NOTES" The order of operations is significant. This can be used to set either defaults or values which cannot be overridden. For example if an application calls: .PP .Vb 2 \& SSL_CONF_cmd(ctx, "Protocol", "\-SSLv3"); \& SSL_CONF_cmd(ctx, userparam, uservalue); .Ve .PP it will disable SSLv3 support by default but the user can override it. If however the call sequence is: .PP .Vb 2 \& SSL_CONF_cmd(ctx, userparam, uservalue); \& SSL_CONF_cmd(ctx, "Protocol", "\-SSLv3"); .Ve .PP SSLv3 is \fBalways\fR disabled and attempt to override this by the user are ignored. .PP By checking the return code of \fBSSL_CONF_cmd()\fR it is possible to query if a given \fBcmd\fR is recognised, this is useful if \fBSSL_CONF_cmd()\fR values are mixed with additional application specific operations. .PP For example an application might call \fBSSL_CONF_cmd()\fR and if it returns \&\-2 (unrecognised command) continue with processing of application specific commands. .PP Applications can also use \fBSSL_CONF_cmd()\fR to process command lines though the utility function \fBSSL_CONF_cmd_argv()\fR is normally used instead. One way to do this is to set the prefix to an appropriate value using \&\fBSSL_CONF_CTX_set1_prefix()\fR, pass the current argument to \fBcmd\fR and the following argument to \fBvalue\fR (which may be \s-1NULL\s0). .PP In this case if the return value is positive then it is used to skip that number of arguments as they have been processed by \fBSSL_CONF_cmd()\fR. If \-2 is returned then \fBcmd\fR is not recognised and application specific arguments can be checked instead. If \-3 is returned a required argument is missing and an error is indicated. If 0 is returned some other error occurred and this can be reported back to the user. .PP The function \fBSSL_CONF_cmd_value_type()\fR can be used by applications to check for the existence of a command or to perform additional syntax checking or translation of the command value. For example if the return value is \fB\s-1SSL_CONF_TYPE_FILE\s0\fR an application could translate a relative pathname to an absolute pathname. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CONF_cmd()\fR returns 1 if the value of \fBcmd\fR is recognised and \fBvalue\fR is \&\fB\s-1NOT\s0\fR used and 2 if both \fBcmd\fR and \fBvalue\fR are used. In other words it returns the number of arguments processed. This is useful when processing command lines. .PP A return value of \-2 means \fBcmd\fR is not recognised. .PP A return value of \-3 means \fBcmd\fR is recognised and the command requires a value but \fBvalue\fR is \s-1NULL.\s0 .PP A return code of 0 indicates that both \fBcmd\fR and \fBvalue\fR are valid but an error occurred attempting to perform the operation: for example due to an error in the syntax of \fBvalue\fR in this case the error queue may provide additional information. .SH "EXAMPLES" .IX Header "EXAMPLES" Set supported signature algorithms: .PP .Vb 1 \& SSL_CONF_cmd(ctx, "SignatureAlgorithms", "ECDSA+SHA256:RSA+SHA256:DSA+SHA256"); .Ve .PP There are various ways to select the supported protocols. .PP This set the minimum protocol version to TLSv1, and so disables SSLv3. This is the recommended way to disable protocols. .PP .Vb 1 \& SSL_CONF_cmd(ctx, "MinProtocol", "TLSv1"); .Ve .PP The following also disables SSLv3: .PP .Vb 1 \& SSL_CONF_cmd(ctx, "Protocol", "\-SSLv3"); .Ve .PP The following will first enable all protocols, and then disable SSLv3. If no protocol versions were disabled before this has the same effect as \&\*(L"\-SSLv3\*(R", but if some versions were disables this will re-enable them before disabling SSLv3. .PP .Vb 1 \& SSL_CONF_cmd(ctx, "Protocol", "ALL,\-SSLv3"); .Ve .PP Only enable TLSv1.2: .PP .Vb 2 \& SSL_CONF_cmd(ctx, "MinProtocol", "TLSv1.2"); \& SSL_CONF_cmd(ctx, "MaxProtocol", "TLSv1.2"); .Ve .PP This also only enables TLSv1.2: .PP .Vb 1 \& SSL_CONF_cmd(ctx, "Protocol", "\-ALL,TLSv1.2"); .Ve .PP Disable \s-1TLS\s0 session tickets: .PP .Vb 1 \& SSL_CONF_cmd(ctx, "Options", "\-SessionTicket"); .Ve .PP Enable compression: .PP .Vb 1 \& SSL_CONF_cmd(ctx, "Options", "Compression"); .Ve .PP Set supported curves to P\-256, P\-384: .PP .Vb 1 \& SSL_CONF_cmd(ctx, "Curves", "P\-256:P\-384"); .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CONF_CTX_new\fR\|(3), \&\fBSSL_CONF_CTX_set_flags\fR\|(3), \&\fBSSL_CONF_CTX_set1_prefix\fR\|(3), \&\fBSSL_CONF_CTX_set_ssl_ctx\fR\|(3), \&\fBSSL_CONF_cmd_argv\fR\|(3), \&\fBSSL_CTX_set_options\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The \fBSSL_CONF_cmd()\fR function was added in OpenSSL 1.0.2. .PP The \fB\s-1SSL_OP_NO_SSL2\s0\fR option doesn't have effect since 1.1.0, but the macro is retained for backwards compatibility. .PP The \fB\s-1SSL_CONF_TYPE_NONE\s0\fR was added in OpenSSL 1.1.0.

It provides a set of functions used by OpenSSL for the implementation of the various \s-1BIO\s0 capabilities. See the bio page for more information. .PP \&\fBBIO_meth_new()\fR creates a new \fB\s-1BIO_METHOD\s0\fR structure. It should be given a unique integer \fBtype\fR and a string that represents its \fBname\fR. Use \fBBIO_get_new_index()\fR to get the value for \fBtype\fR. .PP The set of standard OpenSSL provided \s-1BIO\s0 types is provided in \fBbio.h\fR. Some examples include \fB\s-1BIO_TYPE_BUFFER\s0\fR and \fB\s-1BIO_TYPE_CIPHER\s0\fR. Filter BIOs should have a type which have the \*(L"filter\*(R" bit set (\fB\s-1BIO_TYPE_FILTER\s0\fR). Source/sink BIOs should have the \*(L"source/sink\*(R" bit set (\fB\s-1BIO_TYPE_SOURCE_SINK\s0\fR).

The result is padded with zeros if necessary. If \fBtolen\fR is less than BN_num_bytes(\fBa\fR) an error is returned. .PP \&\fBBN_bin2bn()\fR converts the positive integer in big-endian form of length \&\fBlen\fR at \fBs\fR into a \fB\s-1BIGNUM\s0\fR and places it in \fBret\fR. If \fBret\fR is \&\s-1NULL,\s0 a new \fB\s-1BIGNUM\s0\fR is created. .PP \&\fBBN_bn2lebinpad()\fR and \fBBN_lebin2bn()\fR are identical to \fBBN_bn2binpad()\fR and \&\fBBN_bin2bn()\fR except the buffer is in little-endian format. .PP \&\fBBN_bn2hex()\fR and \fBBN_bn2dec()\fR return printable strings containing the hexadecimal and decimal encoding of \fBa\fR respectively. For negative numbers, the string is prefaced with a leading '\-'. The string must be freed later using \fBOPENSSL_free()\fR. .PP \&\fBBN_hex2bn()\fR takes as many characters as possible from the string \fBstr\fR, including the leading character '\-' which means negative, to form a valid hexadecimal number representation and converts them to a \fB\s-1BIGNUM\s0\fR and stores it in **\fBa\fR. If *\fBa\fR is \s-1NULL,\s0 a new \fB\s-1BIGNUM\s0\fR is created. If \&\fBa\fR is \s-1NULL,\s0 it only computes the length of valid representation. A \*(L"negative zero\*(R" is converted to zero. \&\fBBN_dec2bn()\fR is the same using the decimal system. .PP \&\fBBN_print()\fR and \fBBN_print_fp()\fR write the hexadecimal encoding of \fBa\fR, with a leading '\-' for negative numbers, to the \fB\s-1BIO\s0\fR or \fB\s-1FILE\s0\fR \&\fBfp\fR. .PP \&\fBBN_bn2mpi()\fR and \fBBN_mpi2bn()\fR convert \fB\s-1BIGNUM\s0\fRs from and to a format that consists of the number's length in bytes represented as a 4\-byte big-endian number, and the number itself in big-endian format, where the most significant bit signals a negative number (the representation of numbers with the \s-1MSB\s0 set is prefixed with null byte). .PP \&\fBBN_bn2mpi()\fR stores the representation of \fBa\fR at \fBto\fR, where \fBto\fR must be large enough to hold the result. The size can be determined by calling BN_bn2mpi(\fBa\fR, \s-1NULL\s0). .PP \&\fBBN_mpi2bn()\fR converts the \fBlen\fR bytes long representation at \fBs\fR to a \fB\s-1BIGNUM\s0\fR and stores it at \fBret\fR, or in a newly allocated \fB\s-1BIGNUM\s0\fR if \fBret\fR is \s-1NULL.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBN_bn2bin()\fR returns the length of the big-endian number placed at \fBto\fR. \&\fBBN_bin2bn()\fR returns the \fB\s-1BIGNUM\s0\fR, \s-1NULL\s0 on error. .PP \&\fBBN_bn2binpad()\fR returns the number of bytes written or \-1 if the supplied buffer is too small. .PP \&\fBBN_bn2hex()\fR and \fBBN_bn2dec()\fR return a null-terminated string, or \s-1NULL\s0 on error. \fBBN_hex2bn()\fR and \fBBN_dec2bn()\fR return the number of characters used in parsing, or 0 on error, in which case no new \fB\s-1BIGNUM\s0\fR will be created. .PP \&\fBBN_print_fp()\fR and \fBBN_print()\fR return 1 on success, 0 on write errors. .PP \&\fBBN_bn2mpi()\fR returns the length of the representation. \fBBN_mpi2bn()\fR returns the \fB\s-1BIGNUM\s0\fR, and \s-1NULL\s0 on error. .PP The error codes can be obtained by \fBERR_get_error\fR\|(3). .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBERR_get_error\fR\|(3), \fBBN_zero\fR\|(3), \&\fBASN1_INTEGER_to_BN\fR\|(3), \&\fBBN_num_bytes\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

See the \fB\s-1VERIFICATION FLAGS\s0\fR section for a complete description of values the \fBflags\fR parameter can take. .PP \&\fBX509_VERIFY_PARAM_get_flags()\fR returns the flags in \fBparam\fR. .PP \&\fBX509_VERIFY_PARAM_get_inh_flags()\fR returns the inheritance flags in \fBparam\fR which specifies how verification flags are copied from one structure to another. \fBX509_VERIFY_PARAM_set_inh_flags()\fR sets the inheritance flags. See the \fB\s-1INHERITANCE FLAGS\s0\fR section for a description of these bits. .PP \&\fBX509_VERIFY_PARAM_clear_flags()\fR clears the flags \fBflags\fR in \fBparam\fR. .PP \&\fBX509_VERIFY_PARAM_set_purpose()\fR sets the verification purpose in \fBparam\fR to \fBpurpose\fR. This determines the acceptable purpose of the certificate chain, for example \s-1SSL\s0 client or \s-1SSL\s0 server. .PP \&\fBX509_VERIFY_PARAM_set_trust()\fR sets the trust setting in \fBparam\fR to \&\fBtrust\fR. .PP \&\fBX509_VERIFY_PARAM_set_time()\fR sets the verification time in \fBparam\fR to \&\fBt\fR. Normally the current time is used. .PP \&\fBX509_VERIFY_PARAM_add0_policy()\fR adds \fBpolicy\fR to the acceptable policy set. Contrary to preexisting documentation of this function it does not enable policy checking. .PP \&\fBX509_VERIFY_PARAM_set1_policies()\fR enables policy checking (it is disabled by default) and sets the acceptable policy set to \fBpolicies\fR. Any existing policy set is cleared. The \fBpolicies\fR parameter can be \fB\s-1NULL\s0\fR to clear an existing policy set. .PP \&\fBX509_VERIFY_PARAM_set_depth()\fR sets the maximum verification depth to \fBdepth\fR. That is the maximum number of intermediate \s-1CA\s0 certificates that can appear in a chain. A maximal depth chain contains 2 more certificates than the limit, since neither the end-entity certificate nor the trust-anchor count against this limit. Thus a \fBdepth\fR limit of 0 only allows the end-entity certificate to be signed directly by the trust-anchor, while with a \fBdepth\fR limit of 1 there can be one intermediate \s-1CA\s0 certificate between the trust-anchor and the end-entity certificate. .PP \&\fBX509_VERIFY_PARAM_set_auth_level()\fR sets the authentication security level to \&\fBauth_level\fR. The authentication security level determines the acceptable signature and public key strength when verifying certificate chains. For a certificate chain to validate, the public keys of all the certificates must meet the specified security level. The signature algorithm security level is not enforced for the chain's \fItrust anchor\fR certificate, which is either directly trusted or validated by means other than its signature. See \fBSSL_CTX_set_security_level\fR\|(3) for the definitions of the available levels. The default security level is \-1, or \*(L"not set\*(R". At security level 0 or lower all algorithms are acceptable. Security level 1 requires at least 80\-bit\-equivalent security and is broadly interoperable, though it will, for example, reject \s-1MD5\s0 signatures or \s-1RSA\s0 keys shorter than 1024 bits. .PP \&\fBX509_VERIFY_PARAM_set1_host()\fR sets the expected \s-1DNS\s0 hostname to \&\fBname\fR clearing any previously specified hostname or names. If \&\fBname\fR is \s-1NULL,\s0 or empty the list of hostnames is cleared, and name checks are not performed on the peer certificate. If \fBname\fR is NUL-terminated, \fBnamelen\fR may be zero, otherwise \fBnamelen\fR must be set to the length of \fBname\fR. .PP When a hostname is specified, certificate verification automatically invokes \fBX509_check_host\fR\|(3) with flags equal to the \fBflags\fR argument given to \&\fBX509_VERIFY_PARAM_set_hostflags()\fR (default zero). Applications are strongly advised to use this interface in preference to explicitly calling \fBX509_check_host\fR\|(3), hostname checks may be out of scope with the \s-1\fBDANE\-EE\s0\fR\|(3) certificate usage, and the internal check will be suppressed as appropriate when \s-1DANE\s0 verification is enabled. .PP When the subject CommonName will not be ignored, whether as a result of the \&\fBX509_CHECK_FLAG_ALWAYS_CHECK_SUBJECT\fR host flag, or because no \s-1DNS\s0 subject alternative names are present in the certificate, any \s-1DNS\s0 name constraints in issuer certificates apply to the subject CommonName as well as the subject alternative name extension. .PP When the subject CommonName will be ignored, whether as a result of the \&\fBX509_CHECK_FLAG_NEVER_CHECK_SUBJECT\fR host flag, or because some \s-1DNS\s0 subject alternative names are present in the certificate, \s-1DNS\s0 name constraints in issuer certificates will not be applied to the subject \s-1DN.\s0 As described in \fBX509_check_host\fR\|(3) the \fBX509_CHECK_FLAG_NEVER_CHECK_SUBJECT\fR flag takes precedence over the \fBX509_CHECK_FLAG_ALWAYS_CHECK_SUBJECT\fR flag. .PP \&\fBX509_VERIFY_PARAM_get_hostflags()\fR returns any host flags previously set via a call to \fBX509_VERIFY_PARAM_set_hostflags()\fR. .PP \&\fBX509_VERIFY_PARAM_add1_host()\fR adds \fBname\fR as an additional reference identifier that can match the peer's certificate. Any previous names set via \fBX509_VERIFY_PARAM_set1_host()\fR or \fBX509_VERIFY_PARAM_add1_host()\fR are retained, no change is made if \fBname\fR is \s-1NULL\s0 or empty. When multiple names are configured, the peer is considered verified when any name matches. .PP \&\fBX509_VERIFY_PARAM_get0_peername()\fR returns the \s-1DNS\s0 hostname or subject CommonName from the peer certificate that matched one of the reference identifiers. When wildcard matching is not disabled, or when a reference identifier specifies a parent domain (starts with \*(L".\*(R") rather than a hostname, the peer name may be a wildcard name or a sub-domain of the reference identifier respectively. The return string is allocated by the library and is no longer valid once the associated \fBparam\fR argument is freed. Applications must not free the return value. .PP \&\fBX509_VERIFY_PARAM_set1_email()\fR sets the expected \s-1RFC822\s0 email address to \&\fBemail\fR. If \fBemail\fR is NUL-terminated, \fBemaillen\fR may be zero, otherwise \&\fBemaillen\fR must be set to the length of \fBemail\fR. When an email address is specified, certificate verification automatically invokes \&\fBX509_check_email\fR\|(3). .PP \&\fBX509_VERIFY_PARAM_set1_ip()\fR sets the expected \s-1IP\s0 address to \fBip\fR. The \fBip\fR argument is in binary format, in network byte-order and \&\fBiplen\fR must be set to 4 for IPv4 and 16 for IPv6. When an \s-1IP\s0 address is specified, certificate verification automatically invokes \&\fBX509_check_ip\fR\|(3). .PP \&\fBX509_VERIFY_PARAM_set1_ip_asc()\fR sets the expected \s-1IP\s0 address to \&\fBipasc\fR. The \fBipasc\fR argument is a NUL-terminal \s-1ASCII\s0 string: dotted decimal quad for IPv4 and colon-separated hexadecimal for IPv6. The condensed \*(L"::\*(R" notation is supported for IPv6 addresses. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBX509_VERIFY_PARAM_set_flags()\fR, \fBX509_VERIFY_PARAM_clear_flags()\fR, \&\fBX509_VERIFY_PARAM_set_inh_flags()\fR, \&\fBX509_VERIFY_PARAM_set_purpose()\fR, \fBX509_VERIFY_PARAM_set_trust()\fR, \&\fBX509_VERIFY_PARAM_add0_policy()\fR \fBX509_VERIFY_PARAM_set1_policies()\fR, \&\fBX509_VERIFY_PARAM_set1_host()\fR, \fBX509_VERIFY_PARAM_add1_host()\fR, \&\fBX509_VERIFY_PARAM_set1_email()\fR, \fBX509_VERIFY_PARAM_set1_ip()\fR and \&\fBX509_VERIFY_PARAM_set1_ip_asc()\fR return 1 for success and 0 for failure. .PP \&\fBX509_VERIFY_PARAM_get_flags()\fR returns the current verification flags. .PP \&\fBX509_VERIFY_PARAM_get_hostflags()\fR returns any current host flags. .PP \&\fBX509_VERIFY_PARAM_get_inh_flags()\fR returns the current inheritance flags. .PP \&\fBX509_VERIFY_PARAM_set_time()\fR and \fBX509_VERIFY_PARAM_set_depth()\fR do not return values. .PP \&\fBX509_VERIFY_PARAM_get_depth()\fR returns the current verification depth. .PP \&\fBX509_VERIFY_PARAM_get_auth_level()\fR returns the current authentication security level. .SH "VERIFICATION FLAGS" .IX Header "VERIFICATION FLAGS" The verification flags consists of zero or more of the following flags ored together. .PP \&\fBX509_V_FLAG_CRL_CHECK\fR enables \s-1CRL\s0 checking for the certificate chain leaf certificate. An error occurs if a suitable \s-1CRL\s0 cannot be found. .PP \&\fBX509_V_FLAG_CRL_CHECK_ALL\fR enables \s-1CRL\s0 checking for the entire certificate chain. .PP \&\fBX509_V_FLAG_IGNORE_CRITICAL\fR disabled critical extension checking. By default any unhandled critical extensions in certificates or (if checked) CRLs results in a fatal error. If this flag is set unhandled critical extensions are ignored. \fB\s-1WARNING\s0\fR setting this option for anything other than debugging purposes can be a security risk. Finer control over which extensions are supported can be performed in the verification callback. .PP The \fBX509_V_FLAG_X509_STRICT\fR flag disables workarounds for some broken certificates and makes the verification strictly apply \fBX509\fR rules. .PP \&\fBX509_V_FLAG_ALLOW_PROXY_CERTS\fR enables proxy certificate verification. .PP \&\fBX509_V_FLAG_POLICY_CHECK\fR enables certificate policy checking, by default no policy checking is performed. Additional information is sent to the verification callback relating to policy checking. .PP \&\fBX509_V_FLAG_EXPLICIT_POLICY\fR, \fBX509_V_FLAG_INHIBIT_ANY\fR and \&\fBX509_V_FLAG_INHIBIT_MAP\fR set the \fBrequire explicit policy\fR, \fBinhibit any policy\fR and \fBinhibit policy mapping\fR flags respectively as defined in \&\fB\s-1RFC3280\s0\fR. Policy checking is automatically enabled if any of these flags are set. .PP If \fBX509_V_FLAG_NOTIFY_POLICY\fR is set and the policy checking is successful a special status code is set to the verification callback. This permits it to examine the valid policy tree and perform additional checks or simply log it for debugging purposes. .PP By default some additional features such as indirect CRLs and CRLs signed by different keys are disabled. If \fBX509_V_FLAG_EXTENDED_CRL_SUPPORT\fR is set they are enabled. .PP If \fBX509_V_FLAG_USE_DELTAS\fR is set delta CRLs (if present) are used to determine certificate status. If not set deltas are ignored. .PP \&\fBX509_V_FLAG_CHECK_SS_SIGNATURE\fR requests checking the signature of the last certificate in a chain if the certificate is supposedly self-signed. This is prohibited and will result in an error if it is a non-conforming \s-1CA\s0 certificate with key usage restrictions not including the keyCertSign bit. By default this check is disabled because it doesn't add any additional security but in some cases applications might want to check the signature anyway. A side effect of not checking the self-signature of such a certificate is that disabled or unsupported message digests used for the signature are not treated as fatal errors. .PP When \fBX509_V_FLAG_TRUSTED_FIRST\fR is set, construction of the certificate chain in \fBX509_verify_cert\fR\|(3) will search the trust store for issuer certificates before searching the provided untrusted certificates. Local issuer certificates are often more likely to satisfy local security requirements and lead to a locally trusted root. This is especially important when some certificates in the trust store have explicit trust settings (see \*(L"\s-1TRUST SETTINGS\*(R"\s0 in \fBx509\fR\|(1)). As of OpenSSL 1.1.0 this option is on by default. .PP The \fBX509_V_FLAG_NO_ALT_CHAINS\fR flag suppresses checking for alternative chains. By default, unless \fBX509_V_FLAG_TRUSTED_FIRST\fR is set, when building a certificate chain, if the first certificate chain found is not trusted, then OpenSSL will attempt to replace untrusted certificates supplied by the peer with certificates from the trust store to see if an alternative chain can be found that is trusted. As of OpenSSL 1.1.0, with \fBX509_V_FLAG_TRUSTED_FIRST\fR always set, this option has no effect. .PP The \fBX509_V_FLAG_PARTIAL_CHAIN\fR flag causes intermediate certificates in the trust store to be treated as trust-anchors, in the same way as the self-signed root \s-1CA\s0 certificates. This makes it possible to trust certificates issued by an intermediate \s-1CA\s0 without having to trust its ancestor root \s-1CA.\s0 With OpenSSL 1.1.0 and later and <X509_V_FLAG_PARTIAL_CHAIN> set, chain construction stops as soon as the first certificate from the trust store is added to the chain, whether that certificate is a self-signed \*(L"root\*(R" certificate or a not self-signed intermediate certificate. Thus, when an intermediate certificate is found in the trust store, the verified chain passed to callbacks may be shorter than it otherwise would be without the \fBX509_V_FLAG_PARTIAL_CHAIN\fR flag. .PP The \fBX509_V_FLAG_NO_CHECK_TIME\fR flag suppresses checking the validity period of certificates and CRLs against the current time. If \fBX509_VERIFY_PARAM_set_time()\fR is used to specify a verification time, the check is not suppressed. .SH "INHERITANCE FLAGS" .IX Header "INHERITANCE FLAGS" These flags specify how parameters are \*(L"inherited\*(R" from one structure to another. .PP If \fBX509_VP_FLAG_ONCE\fR is set then the current setting is zeroed after the next call. .PP If \fBX509_VP_FLAG_LOCKED\fR is set then no values are copied. This overrides all of the following flags. .PP If \fBX509_VP_FLAG_DEFAULT\fR is set then anything set in the source is copied to the destination. Effectively the values in \*(L"to\*(R" become default values which will be used only if nothing new is set in \*(L"from\*(R". This is the default. .PP If \fBX509_VP_FLAG_OVERWRITE\fR is set then all value are copied across whether they are set or not. Flags is still Ored though. .PP If \fBX509_VP_FLAG_RESET_FLAGS\fR is set then the flags value is copied instead of ORed. .SH "NOTES" .IX Header "NOTES" The above functions should be used to manipulate verification parameters instead of functions which work in specific structures such as \&\fBX509_STORE_CTX_set_flags()\fR which are likely to be deprecated in a future release. .SH "BUGS" .IX Header "BUGS" Delta \s-1CRL\s0 checking is currently primitive. Only a single delta can be used and (partly due to limitations of \fBX509_STORE\fR) constructed CRLs are not maintained. .PP If CRLs checking is enable CRLs are expected to be available in the corresponding \fBX509_STORE\fR structure.

The format can be \fB\s-1ASCII\s0\fR or \fB\s-1UTF8\s0\fR. .IP "\fB\s-1SEQUENCE\s0\fR, \fB\s-1SEQ\s0\fR, \fB\s-1SET\s0\fR" 4 .IX Item "SEQUENCE, SEQ, SET" Formats the result as an \s-1ASN1\s0 \fB\s-1SEQUENCE\s0\fR or \fB\s-1SET\s0\fR type. \fBvalue\fR should be a section name which will contain the contents. The field names in the section are ignored and the values are in the generated string format. If \fBvalue\fR is absent then an empty \s-1SEQUENCE\s0 will be encoded. .SS "Modifiers" .IX Subsection "Modifiers" Modifiers affect the following structure, they can be used to add \s-1EXPLICIT\s0 or \s-1IMPLICIT\s0 tagging, add wrappers or to change the string format of the final type and value. The supported formats are documented below. .IP "\fB\s-1EXPLICIT\s0\fR, \fB\s-1EXP\s0\fR" 4 .IX Item "EXPLICIT, EXP" Add an explicit tag to the following structure. This string should be followed by a colon and the tag value to use as a decimal value. .Sp By following the number with \fBU\fR, \fBA\fR, \fBP\fR or \fBC\fR \s-1UNIVERSAL, APPLICATION, PRIVATE\s0 or \s-1CONTEXT SPECIFIC\s0 tagging can be used, the default is \s-1CONTEXT SPECIFIC.\s0 .IP "\fB\s-1IMPLICIT\s0\fR, \fB\s-1IMP\s0\fR" 4 .IX Item "IMPLICIT, IMP" This is the same as \fB\s-1EXPLICIT\s0\fR except \s-1IMPLICIT\s0 tagging is used instead. .IP "\fB\s-1OCTWRAP\s0\fR, \fB\s-1SEQWRAP\s0\fR, \fB\s-1SETWRAP\s0\fR, \fB\s-1BITWRAP\s0\fR" 4 .IX Item "OCTWRAP, SEQWRAP, SETWRAP, BITWRAP" The following structure is surrounded by an \s-1OCTET STRING,\s0 a \s-1SEQUENCE,\s0 a \s-1SET\s0 or a \s-1BIT STRING\s0 respectively. For a \s-1BIT STRING\s0 the number of unused bits is set to zero. .IP "\fB\s-1FORMAT\s0\fR" 4 .IX Item "FORMAT" This specifies the format of the ultimate value. It should be followed by a colon and one of the strings \fB\s-1ASCII\s0\fR, \fB\s-1UTF8\s0\fR, \fB\s-1HEX\s0\fR or \fB\s-1BITLIST\s0\fR. .Sp If no format specifier is included then \fB\s-1ASCII\s0\fR is used. If \fB\s-1UTF8\s0\fR is specified then the value string must be a valid \fB\s-1UTF8\s0\fR string. For \fB\s-1HEX\s0\fR the output must be a set of hex digits. \fB\s-1BITLIST\s0\fR (which is only valid for a \s-1BIT STRING\s0) is a comma separated list of the indices of the set bits, all other bits are zero. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBASN1_generate_nconf()\fR and \fBASN1_generate_v3()\fR return the encoded data as an \fB\s-1ASN1_TYPE\s0\fR structure or \fB\s-1NULL\s0\fR if an error occurred. .PP The error codes that can be obtained by \fBERR_get_error\fR\|(3). .SH "EXAMPLES" .IX Header "EXAMPLES" A simple IA5String: .PP .Vb 1 \& IA5STRING:Hello World .Ve .PP An IA5String explicitly tagged: .PP .Vb 1 \& EXPLICIT:0,IA5STRING:Hello World .Ve .PP An IA5String explicitly tagged using \s-1APPLICATION\s0 tagging: .PP .Vb 1 \& EXPLICIT:0A,IA5STRING:Hello World .Ve .PP A \s-1BITSTRING\s0 with bits 1 and 5 set and all others zero: .PP .Vb 1 \& FORMAT:BITLIST,BITSTRING:1,5 .Ve .PP A more complex example using a config file to produce a \&\s-1SEQUENCE\s0 consisting of a \s-1BOOL\s0 an \s-1OID\s0 and a UTF8String: .PP .Vb 1 \& asn1 = SEQUENCE:seq_section \& \& [seq_section] \& \& field1 = BOOLEAN:TRUE \& field2 = OID:commonName \& field3 = UTF8:Third field .Ve .PP This example produces an RSAPrivateKey structure, this is the key contained in the file client.pem in all OpenSSL distributions (note: the field names such as 'coeff' are ignored and are present just for clarity): .PP .Vb 3 \& asn1=SEQUENCE:private_key \& [private_key] \& version=INTEGER:0 \& \& n=INTEGER:0xBB6FE79432CC6EA2D8F970675A5A87BFBE1AFF0BE63E879F2AFFB93644\e \& D4D2C6D000430DEC66ABF47829E74B8C5108623A1C0EE8BE217B3AD8D36D5EB4FCA1D9 \& \& e=INTEGER:0x010001 \& \& d=INTEGER:0x6F05EAD2F27FFAEC84BEC360C4B928FD5F3A9865D0FCAAD291E2A52F4A\e \& F810DC6373278C006A0ABBA27DC8C63BF97F7E666E27C5284D7D3B1FFFE16B7A87B51D \& \& p=INTEGER:0xF3929B9435608F8A22C208D86795271D54EBDFB09DDEF539AB083DA912\e \& D4BD57 \& \& q=INTEGER:0xC50016F89DFF2561347ED1186A46E150E28BF2D0F539A1594BBD7FE467\e \& 46EC4F \& \& exp1=INTEGER:0x9E7D4326C924AFC1DEA40B45650134966D6F9DFA3A7F9D698CD4ABEA\e \& 9C0A39B9 \& \& exp2=INTEGER:0xBA84003BB95355AFB7C50DF140C60513D0BA51D637272E355E397779\e \& E7B2458F \& \& coeff=INTEGER:0x30B9E4F2AFA5AC679F920FC83F1F2DF1BAF1779CF989447FABC2F5\e \& 628657053A .Ve .PP This example is the corresponding public key in a SubjectPublicKeyInfo structure: .PP .Vb 2 \& # Start with a SEQUENCE \& asn1=SEQUENCE:pubkeyinfo \& \& # pubkeyinfo contains an algorithm identifier and the public key wrapped \& # in a BIT STRING \& [pubkeyinfo] \& algorithm=SEQUENCE:rsa_alg \& pubkey=BITWRAP,SEQUENCE:rsapubkey \& \& # algorithm ID for RSA is just an OID and a NULL \& [rsa_alg] \& algorithm=OID:rsaEncryption \& parameter=NULL \& \& # Actual public key: modulus and exponent \& [rsapubkey] \& n=INTEGER:0xBB6FE79432CC6EA2D8F970675A5A87BFBE1AFF0BE63E879F2AFFB93644\e \& D4D2C6D000430DEC66ABF47829E74B8C5108623A1C0EE8BE217B3AD8D36D5EB4FCA1D9 \& \& e=INTEGER:0x010001 .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBERR_get_error\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2002\-2019 The OpenSSL Project Authors.

These functions cannot be used for TLSv1.2 and below PSKs. .PP The callback function is given a pointer to the \s-1SSL\s0 connection in \fBssl\fR. .PP The first time the callback is called for a connection the \fBmd\fR parameter is \&\s-1NULL.\s0 In some circumstances the callback will be called a second time. In that case the server will have specified a ciphersuite to use already and the \s-1PSK\s0 must be compatible with the digest for that ciphersuite. The digest will be given in \fBmd\fR. The \s-1PSK\s0 returned by the callback is allowed to be different between the first and second time it is called. .PP On successful completion the callback must store a pointer to an identifier for the \s-1PSK\s0 in \fB*id\fR. The identifier length in bytes should be stored in \fB*idlen\fR. The memory pointed to by \fB*id\fR remains owned by the application and should be freed by it as required at any point after the handshake is complete. .PP Additionally the callback should store a pointer to an \s-1SSL_SESSION\s0 object in \&\fB*sess\fR. This is used as the basis for the \s-1PSK,\s0 and should, at a minimum, have the following fields set: .IP "The master key" 4 .IX Item "The master key" This can be set via a call to \fBSSL_SESSION_set1_master_key\fR\|(3). .IP "A ciphersuite" 4 .IX Item "A ciphersuite" Only the handshake digest associated with the ciphersuite is relevant for the \&\s-1PSK\s0 (the server may go on to negotiate any ciphersuite which is compatible with the digest). The application can use any TLSv1.3 ciphersuite. If \fBmd\fR is not \s-1NULL\s0 the handshake digest for the ciphersuite should be the same. The ciphersuite can be set via a call to <\fBSSL_SESSION_set_cipher\fR\|(3)>. The handshake digest of an \s-1SSL_CIPHER\s0 object can be checked using <\fBSSL_CIPHER_get_handshake_digest\fR\|(3)>. .IP "The protocol version" 4 .IX Item "The protocol version" This can be set via a call to \fBSSL_SESSION_set_protocol_version\fR\|(3) and should be \s-1TLS1_3_VERSION.\s0 .PP Additionally the maximum early data value should be set via a call to \&\fBSSL_SESSION_set_max_early_data\fR\|(3) if the \s-1PSK\s0 will be used for sending early data. .PP Alternatively an \s-1SSL_SESSION\s0 created from a previous non-PSK handshake may also be used as the basis for a \s-1PSK.\s0 .PP Ownership of the \s-1SSL_SESSION\s0 object is passed to the OpenSSL library and so it should not be freed by the application. .PP It is also possible for the callback to succeed but not supply a \s-1PSK.\s0 In this case no \s-1PSK\s0 will be sent to the server but the handshake will continue. To do this the callback should return successfully and ensure that \fB*sess\fR is \&\s-1NULL.\s0 The contents of \fB*id\fR and \fB*idlen\fR will be ignored. .PP A client application wishing to use \s-1PSK\s0 ciphersuites for TLSv1.2 and below must provide a different callback function. This function will be called when the client is sending the ClientKeyExchange message to the server. .PP The purpose of the callback function is to select the \s-1PSK\s0 identity and the pre-shared key to use during the connection setup phase. .PP The callback is set using functions \fBSSL_CTX_set_psk_client_callback()\fR or \fBSSL_set_psk_client_callback()\fR. The callback function is given the connection in parameter \fBssl\fR, a \fB\s-1NULL\s0\fR\-terminated \s-1PSK\s0 identity hint sent by the server in parameter \fBhint\fR, a buffer \fBidentity\fR of length \fBmax_identity_len\fR bytes where the resulting \&\fB\s-1NUL\s0\fR\-terminated identity is to be stored, and a buffer \fBpsk\fR of length \fBmax_psk_len\fR bytes where the resulting pre-shared key is to be stored. .PP The callback for use in TLSv1.2 will also work in TLSv1.3 although it is recommended to use \fBSSL_CTX_set_psk_use_session_callback()\fR or \fBSSL_set_psk_use_session_callback()\fR for this purpose instead. If TLSv1.3 has been negotiated then OpenSSL will first check to see if a callback has been set via \fBSSL_CTX_set_psk_use_session_callback()\fR or \fBSSL_set_psk_use_session_callback()\fR and it will use that in preference. If no such callback is present then it will check to see if a callback has been set via \fBSSL_CTX_set_psk_client_callback()\fR or \&\fBSSL_set_psk_client_callback()\fR and use that. In this case the \fBhint\fR value will always be \s-1NULL\s0 and the handshake digest will default to \s-1SHA\-256\s0 for any returned \&\s-1PSK.\s0 TLSv1.3 early data exchanges are possible in \s-1PSK\s0 connections only with the \&\fBSSL_psk_use_session_cb_func\fR callback, and are not possible with the \&\fBSSL_psk_client_cb_func\fR callback. .SH "NOTES" .IX Header "NOTES" Note that parameter \fBhint\fR given to the callback may be \fB\s-1NULL\s0\fR. .PP A connection established via a TLSv1.3 \s-1PSK\s0 will appear as if session resumption has occurred so that \fBSSL_session_reused\fR\|(3) will return true. .PP There are no known security issues with sharing the same \s-1PSK\s0 between TLSv1.2 (or below) and TLSv1.3. However, the \s-1RFC\s0 has this note of caution: .PP \&\*(L"While there is no known way in which the same \s-1PSK\s0 might produce related output in both versions, only limited analysis has been done.

In this case the connection setup fails. .PP The SSL_psk_use_session_cb_func callback should return 1 on success or 0 on failure. In the event of failure the connection setup fails. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CTX_set_psk_find_session_callback\fR\|(3), \&\fBSSL_set_psk_find_session_callback\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fBSSL_CTX_set_psk_use_session_callback()\fR and \fBSSL_set_psk_use_session_callback()\fR were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2006\-2020 The OpenSSL Project Authors.

Changes made to this context will affect the digest \&\s-1BIO\s0 itself and the context pointer will become invalid when the digest \&\s-1BIO\s0 is freed. .PP After the digest has been retrieved from a digest \s-1BIO\s0 it must be reinitialized by calling \fBBIO_reset()\fR, or \fBBIO_set_md()\fR before any more data is passed through it. .PP If an application needs to call \fBBIO_gets()\fR or \fBBIO_puts()\fR through a chain containing digest BIOs then this can be done by prepending a buffering \s-1BIO.\s0 .PP Calling \fBBIO_get_md_ctx()\fR will return the context and initialize the \s-1BIO\s0 state. This allows applications to initialize the context externally if the standard calls such as \fBBIO_set_md()\fR are not sufficiently flexible. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_f_md()\fR returns the digest \s-1BIO\s0 method. .PP \&\fBBIO_set_md()\fR, \fBBIO_get_md()\fR and \fBBIO_md_ctx()\fR return 1 for success and 0 for failure. .SH "EXAMPLES" .IX Header "EXAMPLES" The following example creates a \s-1BIO\s0 chain containing an \s-1SHA1\s0 and \s-1MD5\s0 digest \s-1BIO\s0 and passes the string \*(L"Hello World\*(R" through it. Error checking has been omitted for clarity. .PP .Vb 2 \& BIO *bio, *mdtmp; \& char message[] = "Hello World"; \& \& bio = BIO_new(BIO_s_null()); \& mdtmp = BIO_new(BIO_f_md()); \& BIO_set_md(mdtmp, EVP_sha1()); \& /* \& * For BIO_push() we want to append the sink BIO and keep a note of \& * the start of the chain. \& */ \& bio = BIO_push(mdtmp, bio); \& mdtmp = BIO_new(BIO_f_md()); \& BIO_set_md(mdtmp, EVP_md5()); \& bio = BIO_push(mdtmp, bio); \& /* Note: mdtmp can now be discarded */ \& BIO_write(bio, message, strlen(message)); .Ve .PP The next example digests data by reading through a chain instead: .PP .Vb 3 \& BIO *bio, *mdtmp; \& char buf[1024]; \& int rdlen; \& \& bio = BIO_new_file(file, "rb"); \& mdtmp = BIO_new(BIO_f_md()); \& BIO_set_md(mdtmp, EVP_sha1()); \& bio = BIO_push(mdtmp, bio); \& mdtmp = BIO_new(BIO_f_md()); \& BIO_set_md(mdtmp, EVP_md5()); \& bio = BIO_push(mdtmp, bio); \& do { \& rdlen = BIO_read(bio, buf, sizeof(buf)); \& /* Might want to do something with the data here */ \& } while (rdlen > 0); .Ve .PP This next example retrieves the message digests from a \s-1BIO\s0 chain and outputs them. This could be used with the examples above. .PP .Vb 4 \& BIO *mdtmp; \& unsigned char mdbuf[EVP_MAX_MD_SIZE]; \& int mdlen; \& int i; \& \& mdtmp = bio; /* Assume bio has previously been set up */ \& do { \& EVP_MD *md; \& \& mdtmp = BIO_find_type(mdtmp, BIO_TYPE_MD); \& if (!mdtmp) \& break; \& BIO_get_md(mdtmp, &md); \& printf("%s digest", OBJ_nid2sn(EVP_MD_type(md))); \& mdlen = BIO_gets(mdtmp, mdbuf, EVP_MAX_MD_SIZE); \& for (i = 0; i < mdlen; i++) printf(":%02X", mdbuf[i]); \& printf("\en"); \& mdtmp = BIO_next(mdtmp); \& } while (mdtmp); \& \& BIO_free_all(bio); .Ve .SH "BUGS" .IX Header "BUGS" The lack of support for \fBBIO_puts()\fR and the non standard behaviour of \&\fBBIO_gets()\fR could be regarded as anomalous. It could be argued that \fBBIO_gets()\fR and \fBBIO_puts()\fR should be passed to the next \s-1BIO\s0 in the chain and digest the data passed through and that digests should be retrieved using a separate \fBBIO_ctrl()\fR call. .SH "HISTORY" .IX Header "HISTORY" Before OpenSSL 1.0.0., the call to \fBBIO_get_md_ctx()\fR would only work if the \&\s-1BIO\s0 was initialized first. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2016 The OpenSSL Project Authors.

It is included for compatibility with older versions of OpenSSL. .PP \&\fBOPENSSL_malloc()\fR, \fBOPENSSL_realloc()\fR, and \fBOPENSSL_free()\fR are like the C \fBmalloc()\fR, \fBrealloc()\fR, and \fBfree()\fR functions. \&\fBOPENSSL_zalloc()\fR calls \fBmemset()\fR to zero the memory before returning. .PP \&\fBOPENSSL_clear_realloc()\fR and \fBOPENSSL_clear_free()\fR should be used when the buffer at \fBaddr\fR holds sensitive information. The old buffer is filled with zero's by calling \fBOPENSSL_cleanse()\fR before ultimately calling \fBOPENSSL_free()\fR. .PP \&\fBOPENSSL_cleanse()\fR fills \fBptr\fR of size \fBlen\fR with a string of 0's. Use \fBOPENSSL_cleanse()\fR with care if the memory is a mapping of a file. If the storage controller uses write compression, then it's possible that sensitive tail bytes will survive zeroization because the block of zeros will be compressed. If the storage controller uses wear leveling, then the old sensitive data will not be overwritten; rather, a block of 0's will be written at a new physical location. .PP \&\fBOPENSSL_strdup()\fR, \fBOPENSSL_strndup()\fR and \fBOPENSSL_memdup()\fR are like the equivalent C functions, except that memory is allocated by calling the \&\fBOPENSSL_malloc()\fR and should be released by calling \fBOPENSSL_free()\fR. .PP \&\fBOPENSSL_strlcpy()\fR, \&\fBOPENSSL_strlcat()\fR and \fBOPENSSL_strnlen()\fR are equivalents of the common C library functions and are provided for portability. .PP \&\fBOPENSSL_hexstr2buf()\fR parses \fBstr\fR as a hex string and returns a pointer to the parsed value. The memory is allocated by calling \&\fBOPENSSL_malloc()\fR and should be released by calling \fBOPENSSL_free()\fR. If \fBlen\fR is not \s-1NULL,\s0 it is filled in with the output length. Colons between two-character hex \*(L"bytes\*(R" are ignored. An odd number of hex digits is an error. .PP \&\fBOPENSSL_buf2hexstr()\fR takes the specified buffer and length, and returns a hex string for value, or \s-1NULL\s0 on error. \&\fBBuffer\fR cannot be \s-1NULL\s0; if \fBlen\fR is 0 an empty string is returned. .PP \&\fBOPENSSL_hexchar2int()\fR converts a character to the hexadecimal equivalent, or returns \-1 on error. .PP If no allocations have been done, it is possible to \*(L"swap out\*(R" the default implementations for \fBOPENSSL_malloc()\fR, OPENSSL_realloc and \fBOPENSSL_free()\fR and replace them with alternate versions (hooks). \&\fBCRYPTO_get_mem_functions()\fR function fills in the given arguments with the function pointers for the current implementations. With \fBCRYPTO_set_mem_functions()\fR, you can specify a different set of functions. If any of \fBm\fR, \fBr\fR, or \fBf\fR are \s-1NULL,\s0 then the function is not changed. .PP The default implementation can include some debugging capability (if enabled at build-time). This adds some overhead by keeping a list of all memory allocations, and removes items from the list when they are free'd. This is most useful for identifying memory leaks. \&\fBCRYPTO_set_mem_debug()\fR turns this tracking on and off. In order to have any effect, is must be called before any of the allocation functions (e.g., \fBCRYPTO_malloc()\fR) are called, and is therefore normally one of the first lines of \fBmain()\fR in an application. \&\fBCRYPTO_mem_ctrl()\fR provides fine-grained control of memory leak tracking. To enable tracking call \fBCRYPTO_mem_ctrl()\fR with a \fBmode\fR argument of the \fB\s-1CRYPTO_MEM_CHECK_ON\s0\fR. To disable tracking call \fBCRYPTO_mem_ctrl()\fR with a \fBmode\fR argument of the \fB\s-1CRYPTO_MEM_CHECK_OFF\s0\fR. .PP While checking memory, it can be useful to store additional context about what is being done. For example, identifying the field names when parsing a complicated data structure. \&\fBOPENSSL_mem_debug_push()\fR (which calls \fBCRYPTO_mem_debug_push()\fR) attaches an identifying string to the allocation stack. This must be a global or other static string; it is not copied. \&\fBOPENSSL_mem_debug_pop()\fR removes identifying state from the stack. .PP At the end of the program, calling \fBCRYPTO_mem_leaks()\fR or \&\fBCRYPTO_mem_leaks_fp()\fR will report all \*(L"leaked\*(R" memory, writing it to the specified \s-1BIO\s0 \fBb\fR or \s-1FILE\s0 \fBfp\fR. These functions return 1 if there are no leaks, 0 if there are leaks and \-1 if an error occurred. .PP \&\fBCRYPTO_mem_leaks_cb()\fR does the same as \fBCRYPTO_mem_leaks()\fR, but instead of writing to a given \s-1BIO,\s0 the callback function is called for each output string with the string, length, and userdata \fBu\fR as the callback parameters. .PP If the library is built with the \f(CW\*(C`crypto\-mdebug\*(C'\fR option, then one function, \fBCRYPTO_get_alloc_counts()\fR, and two additional environment variables, \fB\s-1OPENSSL_MALLOC_FAILURES\s0\fR and \fB\s-1OPENSSL_MALLOC_FD\s0\fR, are available. .PP The function \fBCRYPTO_get_alloc_counts()\fR fills in the number of times each of \fBCRYPTO_malloc()\fR, \fBCRYPTO_realloc()\fR, and \fBCRYPTO_free()\fR have been called, into the values pointed to by \fBmcount\fR, \fBrcount\fR, and \fBfcount\fR, respectively. If a pointer is \s-1NULL,\s0 then the corresponding count is not stored. .PP The variable \&\fB\s-1OPENSSL_MALLOC_FAILURES\s0\fR controls how often allocations should fail. It is a set of fields separated by semicolons, which each field is a count (defaulting to zero) and an optional atsign and percentage (defaulting to 100). If the count is zero, then it lasts forever. For example, \&\f(CW\*(C`100;@25\*(C'\fR or \f(CW\*(C`100@0;0@25\*(C'\fR means the first 100 allocations pass, then all other allocations (until the program exits or crashes) have a 25% chance of failing. .PP If the variable \fB\s-1OPENSSL_MALLOC_FD\s0\fR is parsed as a positive integer, then it is taken as an open file descriptor, and a record of all allocations is written to that descriptor. If an allocation will fail, and the platform supports it, then a backtrace will be written to the descriptor. This can be useful because a malloc may fail but not be checked, and problems will only occur later. The following example in classic shell syntax shows how to use this (will not work on all platforms): .PP .Vb 5 \& OPENSSL_MALLOC_FAILURES=\*(Aq200;@10\*(Aq \& export OPENSSL_MALLOC_FAILURES \& OPENSSL_MALLOC_FD=3 \& export OPENSSL_MALLOC_FD \& ...app invocation... 3>/tmp/log$$ .Ve .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOPENSSL_malloc_init()\fR, \fBOPENSSL_free()\fR, \fBOPENSSL_clear_free()\fR \&\fBCRYPTO_free()\fR, \fBCRYPTO_clear_free()\fR and \fBCRYPTO_get_mem_functions()\fR return no value. .PP \&\fBCRYPTO_mem_leaks()\fR, \fBCRYPTO_mem_leaks_fp()\fR and \fBCRYPTO_mem_leaks_cb()\fR return 1 if there are no leaks, 0 if there are leaks and \-1 if an error occurred. .PP \&\fBOPENSSL_malloc()\fR, \fBOPENSSL_zalloc()\fR, \fBOPENSSL_realloc()\fR, \&\fBOPENSSL_clear_realloc()\fR, \&\fBCRYPTO_malloc()\fR, \fBCRYPTO_zalloc()\fR, \fBCRYPTO_realloc()\fR, \&\fBCRYPTO_clear_realloc()\fR, \&\fBOPENSSL_buf2hexstr()\fR, \fBOPENSSL_hexstr2buf()\fR, \&\fBOPENSSL_strdup()\fR, and \fBOPENSSL_strndup()\fR return a pointer to allocated memory or \s-1NULL\s0 on error. .PP \&\fBCRYPTO_set_mem_functions()\fR and \fBCRYPTO_set_mem_debug()\fR return 1 on success or 0 on failure (almost always because allocations have already happened). .PP \&\fBCRYPTO_mem_ctrl()\fR returns \-1 if an error occurred, otherwise the previous value of the mode. .PP \&\fBOPENSSL_mem_debug_push()\fR and \fBOPENSSL_mem_debug_pop()\fR return 1 on success or 0 on failure. .SH "NOTES" .IX Header "NOTES" While it's permitted to swap out only a few and not all the functions with \fBCRYPTO_set_mem_functions()\fR, it's recommended to swap them all out at once. \fIThis applies specially if OpenSSL was built with the configuration option\fR \f(CW\*(C`crypto\-mdebug\*(C'\fR \fIenabled.

The session id is an arbitrary sequence of bytes. The length of the session id is between 1 and 32 bytes. The session id is not security critical but must be unique for the server. Additionally, the session id is transmitted in the clear when reusing the session so it must not contain sensitive information. .PP Without a callback being set, an OpenSSL server will generate a unique session id from pseudo random numbers of the maximum possible length. Using the callback function, the session id can be changed to contain additional information like e.g. a host id in order to improve load balancing or external caching techniques. .PP The callback function receives a pointer to the memory location to put \&\fBid\fR into and a pointer to the maximum allowed length \fBid_len\fR. The buffer at location \fBid\fR is only guaranteed to have the size \fBid_len\fR. The callback is only allowed to generate a shorter id and reduce \fBid_len\fR; the callback \fBmust never\fR increase \fBid_len\fR or write to the location \&\fBid\fR exceeding the given limit. .PP The location \fBid\fR is filled with 0x00 before the callback is called, so the callback may only fill part of the possible length and leave \fBid_len\fR untouched while maintaining reproducibility. .PP Since the sessions must be distinguished, session ids must be unique. Without the callback a random number is used, so that the probability of generating the same session id is extremely small (2^256 for SSLv3/TLSv1). In order to assure the uniqueness of the generated session id, the callback must call \&\fBSSL_has_matching_session_id()\fR and generate another id if a conflict occurs. If an id conflict is not resolved, the handshake will fail. If the application codes e.g. a unique host id, a unique process number, and a unique sequence number into the session id, uniqueness could easily be achieved without randomness added (it should however be taken care that no confidential information is leaked this way). If the application can not guarantee uniqueness, it is recommended to use the maximum \fBid_len\fR and fill in the bytes not used to code special information with random data to avoid collisions. .PP \&\fBSSL_has_matching_session_id()\fR will only query the internal session cache, not the external one. Since the session id is generated before the handshake is completed, it is not immediately added to the cache. If another thread is using the same internal session cache, a race condition can occur in that another thread generates the same session id. Collisions can also occur when using an external session cache, since the external cache is not tested with \fBSSL_has_matching_session_id()\fR and the same race condition applies. .PP The callback must return 0 if it cannot generate a session id for whatever reason and return 1 on success. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set_generate_session_id()\fR and \fBSSL_set_generate_session_id()\fR always return 1. .PP \&\fBSSL_has_matching_session_id()\fR returns 1 if another session with the same id is already in the cache. .SH "EXAMPLES" .IX Header "EXAMPLES" The callback function listed will generate a session id with the server id given, and will fill the rest with pseudo random bytes: .PP .Vb 1 \& const char session_id_prefix = "www\-18"; \& \& #define MAX_SESSION_ID_ATTEMPTS 10 \& static int generate_session_id(SSL *ssl, unsigned char *id, \& unsigned int *id_len) \& { \& unsigned int count = 0; \& \& do { \& RAND_pseudo_bytes(id, *id_len); \& /* \& * Prefix the session_id with the required prefix.

The digest value is placed in \fBmd\fR and its length is written at \fBsize\fR if the pointer is not \s-1NULL.\s0 At most \fB\s-1EVP_MAX_MD_SIZE\s0\fR bytes will be written. If \fBimpl\fR is \s-1NULL\s0 the default implementation of digest \fBtype\fR is used. .IP "\fBEVP_DigestInit_ex()\fR" 4 .IX Item "EVP_DigestInit_ex()" Sets up digest context \fBctx\fR to use a digest \fBtype\fR from \s-1ENGINE\s0 \fBimpl\fR. \&\fBtype\fR will typically be supplied by a function such as \fBEVP_sha1()\fR. If \&\fBimpl\fR is \s-1NULL\s0 then the default implementation of digest \fBtype\fR is used. .IP "\fBEVP_DigestUpdate()\fR" 4 .IX Item "EVP_DigestUpdate()" Hashes \fBcnt\fR bytes of data at \fBd\fR into the digest context \fBctx\fR. This function can be called several times on the same \fBctx\fR to hash additional data. .IP "\fBEVP_DigestFinal_ex()\fR" 4 .IX Item "EVP_DigestFinal_ex()" Retrieves the digest value from \fBctx\fR and places it in \fBmd\fR. If the \fBs\fR parameter is not \s-1NULL\s0 then the number of bytes of data written (i.e. the length of the digest) will be written to the integer at \fBs\fR, at most \&\fB\s-1EVP_MAX_MD_SIZE\s0\fR bytes will be written. After calling \fBEVP_DigestFinal_ex()\fR no additional calls to \fBEVP_DigestUpdate()\fR can be made, but \&\fBEVP_DigestInit_ex()\fR can be called to initialize a new digest operation. .IP "\fBEVP_DigestFinalXOF()\fR" 4 .IX Item "EVP_DigestFinalXOF()" Interfaces to extendable-output functions, XOFs, such as \s-1SHAKE128\s0 and \s-1SHAKE256.\s0 It retrieves the digest value from \fBctx\fR and places it in \fBlen\fR\-sized <B>md. After calling this function no additional calls to \fBEVP_DigestUpdate()\fR can be made, but \fBEVP_DigestInit_ex()\fR can be called to initialize a new operation. .IP "\fBEVP_MD_CTX_copy_ex()\fR" 4 .IX Item "EVP_MD_CTX_copy_ex()" Can be used to copy the message digest state from \fBin\fR to \fBout\fR. This is useful if large amounts of data are to be hashed which only differ in the last few bytes. .IP "\fBEVP_DigestInit()\fR" 4 .IX Item "EVP_DigestInit()" Behaves in the same way as \fBEVP_DigestInit_ex()\fR except it always uses the default digest implementation and calls \fBEVP_MD_CTX_reset()\fR. .IP "\fBEVP_DigestFinal()\fR" 4 .IX Item "EVP_DigestFinal()" Similar to \fBEVP_DigestFinal_ex()\fR except the digest context \fBctx\fR is automatically cleaned up. .IP "\fBEVP_MD_CTX_copy()\fR" 4 .IX Item "EVP_MD_CTX_copy()" Similar to \fBEVP_MD_CTX_copy_ex()\fR except the destination \fBout\fR does not have to be initialized. .IP "\fBEVP_MD_size()\fR, \fBEVP_MD_CTX_size()\fR" 4 .IX Item "EVP_MD_size(), EVP_MD_CTX_size()" Return the size of the message digest when passed an \fB\s-1EVP_MD\s0\fR or an \&\fB\s-1EVP_MD_CTX\s0\fR structure, i.e. the size of the hash. .IP "\fBEVP_MD_block_size()\fR, \fBEVP_MD_CTX_block_size()\fR" 4 .IX Item "EVP_MD_block_size(), EVP_MD_CTX_block_size()" Return the block size of the message digest when passed an \fB\s-1EVP_MD\s0\fR or an \&\fB\s-1EVP_MD_CTX\s0\fR structure. .IP "\fBEVP_MD_type()\fR, \fBEVP_MD_CTX_type()\fR" 4 .IX Item "EVP_MD_type(), EVP_MD_CTX_type()" Return the \s-1NID\s0 of the \s-1OBJECT IDENTIFIER\s0 representing the given message digest when passed an \fB\s-1EVP_MD\s0\fR structure. For example, \f(CW\*(C`EVP_MD_type(EVP_sha1())\*(C'\fR returns \fBNID_sha1\fR. This function is normally used when setting \s-1ASN1\s0 OIDs. .IP "\fBEVP_MD_CTX_md_data()\fR" 4 .IX Item "EVP_MD_CTX_md_data()" Return the digest method private data for the passed \fB\s-1EVP_MD_CTX\s0\fR. The space is allocated by OpenSSL and has the size originally set with \&\fBEVP_MD_meth_set_app_datasize()\fR. .IP "\fBEVP_MD_CTX_md()\fR" 4 .IX Item "EVP_MD_CTX_md()" Returns the \fB\s-1EVP_MD\s0\fR structure corresponding to the passed \fB\s-1EVP_MD_CTX\s0\fR. .IP "\fBEVP_MD_CTX_set_update_fn()\fR" 4 .IX Item "EVP_MD_CTX_set_update_fn()" Sets the update function for \fBctx\fR to \fBupdate\fR. This is the function that is called by EVP_DigestUpdate. If not set, the update function from the \fB\s-1EVP_MD\s0\fR type specified at initialization is used. .IP "\fBEVP_MD_CTX_update_fn()\fR" 4 .IX Item "EVP_MD_CTX_update_fn()" Returns the update function for \fBctx\fR. .IP "\fBEVP_MD_flags()\fR" 4 .IX Item "EVP_MD_flags()" Returns the \fBmd\fR flags. Note that these are different from the \fB\s-1EVP_MD_CTX\s0\fR ones. See \fBEVP_MD_meth_set_flags\fR\|(3) for more information. .IP "\fBEVP_MD_pkey_type()\fR" 4 .IX Item "EVP_MD_pkey_type()" Returns the \s-1NID\s0 of the public key signing algorithm associated with this digest. For example \fBEVP_sha1()\fR is associated with \s-1RSA\s0 so this will return \&\fBNID_sha1WithRSAEncryption\fR. Since digests and signature algorithms are no longer linked this function is only retained for compatibility reasons. .IP "\fBEVP_md_null()\fR" 4 .IX Item "EVP_md_null()" A \*(L"null\*(R" message digest that does nothing: i.e. the hash it returns is of zero length. .IP "\fBEVP_get_digestbyname()\fR, \fBEVP_get_digestbynid()\fR, \fBEVP_get_digestbyobj()\fR" 4 .IX Item "EVP_get_digestbyname(), EVP_get_digestbynid(), EVP_get_digestbyobj()" Returns an \fB\s-1EVP_MD\s0\fR structure when passed a digest name, a digest \fB\s-1NID\s0\fR or an \&\fB\s-1ASN1_OBJECT\s0\fR structure respectively. .IP "\fBEVP_MD_CTX_pkey_ctx()\fR" 4 .IX Item "EVP_MD_CTX_pkey_ctx()" Returns the \fB\s-1EVP_PKEY_CTX\s0\fR assigned to \fBctx\fR. The returned pointer should not be freed by the caller. .IP "\fBEVP_MD_CTX_set_pkey_ctx()\fR" 4 .IX Item "EVP_MD_CTX_set_pkey_ctx()" Assigns an \fB\s-1EVP_PKEY_CTX\s0\fR to \fB\s-1EVP_MD_CTX\s0\fR. This is usually used to provide a customized \fB\s-1EVP_PKEY_CTX\s0\fR to \fBEVP_DigestSignInit\fR\|(3) or \&\fBEVP_DigestVerifyInit\fR\|(3). The \fBpctx\fR passed to this function should be freed by the caller. A \s-1NULL\s0 \fBpctx\fR pointer is also allowed to clear the \fB\s-1EVP_PKEY_CTX\s0\fR assigned to \fBctx\fR. In such case, freeing the cleared \fB\s-1EVP_PKEY_CTX\s0\fR or not depends on how the \fB\s-1EVP_PKEY_CTX\s0\fR is created. .SH "CONTROLS" .IX Header "CONTROLS" \&\fBEVP_MD_CTX_ctrl()\fR can be used to send the following standard controls: .IP "\s-1EVP_MD_CTRL_MICALG\s0" 4 .IX Item "EVP_MD_CTRL_MICALG" Gets the digest Message Integrity Check algorithm string. This is used when creating S/MIME multipart/signed messages, as specified in \s-1RFC 3851.\s0 The string value is written to \fBp2\fR. .IP "\s-1EVP_MD_CTRL_XOF_LEN\s0" 4 .IX Item "EVP_MD_CTRL_XOF_LEN" This control sets the digest length for extendable output functions to \fBp1\fR. Sending this control directly should not be necessary, the use of \&\f(CW\*(C`EVP_DigestFinalXOF()\*(C'\fR is preferred. Currently used by \s-1SHAKE.\s0 .SH "FLAGS" .IX Header "FLAGS" \&\fBEVP_MD_CTX_set_flags()\fR, \fBEVP_MD_CTX_clear_flags()\fR and \fBEVP_MD_CTX_test_flags()\fR can be used the manipulate and test these \fB\s-1EVP_MD_CTX\s0\fR flags: .IP "\s-1EVP_MD_CTX_FLAG_ONESHOT\s0" 4 .IX Item "EVP_MD_CTX_FLAG_ONESHOT" This flag instructs the digest to optimize for one update only, if possible. .IP "\s-1EVP_MD_CTX_FLAG_NO_INIT\s0" 4 .IX Item "EVP_MD_CTX_FLAG_NO_INIT" This flag instructs \fBEVP_DigestInit()\fR and similar not to initialise the implementation specific data. .IP "\s-1EVP_MD_CTX_FLAG_FINALISE\s0" 4 .IX Item "EVP_MD_CTX_FLAG_FINALISE" Some functions such as EVP_DigestSign only finalise copies of internal contexts so additional data can be included after the finalisation call. This is inefficient if this functionality is not required, and can be disabled with this flag. .SH "RETURN VALUES" .IX Header "RETURN VALUES" .IP "\fBEVP_DigestInit_ex()\fR, \fBEVP_DigestUpdate()\fR, \fBEVP_DigestFinal_ex()\fR" 4 .IX Item "EVP_DigestInit_ex(), EVP_DigestUpdate(), EVP_DigestFinal_ex()" Returns 1 for success and 0 for failure. .IP "\fBEVP_MD_CTX_ctrl()\fR" 4 .IX Item "EVP_MD_CTX_ctrl()" Returns 1 if successful or 0 for failure. .IP "\fBEVP_MD_CTX_copy_ex()\fR" 4 .IX Item "EVP_MD_CTX_copy_ex()" Returns 1 if successful or 0 for failure. .IP "\fBEVP_MD_type()\fR, \fBEVP_MD_pkey_type()\fR" 4 .IX Item "EVP_MD_type(), EVP_MD_pkey_type()" Returns the \s-1NID\s0 of the corresponding \s-1OBJECT IDENTIFIER\s0 or NID_undef if none exists. .IP "\fBEVP_MD_size()\fR, \fBEVP_MD_block_size()\fR, \fBEVP_MD_CTX_size()\fR, \fBEVP_MD_CTX_block_size()\fR" 4 .IX Item "EVP_MD_size(), EVP_MD_block_size(), EVP_MD_CTX_size(), EVP_MD_CTX_block_size()" Returns the digest or block size in bytes. .IP "\fBEVP_md_null()\fR" 4 .IX Item "EVP_md_null()" Returns a pointer to the \fB\s-1EVP_MD\s0\fR structure of the \*(L"null\*(R" message digest. .IP "\fBEVP_get_digestbyname()\fR, \fBEVP_get_digestbynid()\fR, \fBEVP_get_digestbyobj()\fR" 4 .IX Item "EVP_get_digestbyname(), EVP_get_digestbynid(), EVP_get_digestbyobj()" Returns either an \fB\s-1EVP_MD\s0\fR structure or \s-1NULL\s0 if an error occurs. .IP "\fBEVP_MD_CTX_set_pkey_ctx()\fR" 4 .IX Item "EVP_MD_CTX_set_pkey_ctx()" This function has no return value. .SH "NOTES" .IX Header "NOTES" The \fB\s-1EVP\s0\fR interface to message digests should almost always be used in preference to the low-level interfaces. This is because the code then becomes transparent to the digest used and much more flexible. .PP New applications should use the \s-1SHA\-2\s0 (such as \fBEVP_sha256\fR\|(3)) or the \s-1SHA\-3\s0 digest algorithms (such as \fBEVP_sha3_512\fR\|(3)). The other digest algorithms are still in common use. .PP For most applications the \fBimpl\fR parameter to \fBEVP_DigestInit_ex()\fR will be set to \s-1NULL\s0 to use the default digest implementation. .PP The functions \fBEVP_DigestInit()\fR, \fBEVP_DigestFinal()\fR and \fBEVP_MD_CTX_copy()\fR are obsolete but are retained to maintain compatibility with existing code. New applications should use \fBEVP_DigestInit_ex()\fR, \fBEVP_DigestFinal_ex()\fR and \&\fBEVP_MD_CTX_copy_ex()\fR because they can efficiently reuse a digest context instead of initializing and cleaning it up on each call and allow non default implementations of digests to be specified. .PP If digest contexts are not cleaned up after use, memory leaks will occur. .PP \&\fBEVP_MD_CTX_size()\fR, \fBEVP_MD_CTX_block_size()\fR, \fBEVP_MD_CTX_type()\fR, \&\fBEVP_get_digestbynid()\fR and \fBEVP_get_digestbyobj()\fR are defined as macros. .PP \&\fBEVP_MD_CTX_ctrl()\fR sends commands to message digests for additional configuration or control. .SH "EXAMPLES" .IX Header "EXAMPLES" This example digests the data \*(L"Test Message\en\*(R" and \*(L"Hello World\en\*(R", using the digest name passed on the command line. .PP .Vb 3 \& #include <stdio.h> \& #include <string.h> \& #include <openssl/evp.h> \& \& int main(int argc, char *argv[]) \& { \& EVP_MD_CTX *mdctx; \& const EVP_MD *md; \& char mess1[] = "Test Message\en"; \& char mess2[] = "Hello World\en"; \& unsigned char md_value[EVP_MAX_MD_SIZE]; \& unsigned int md_len, i; \& \& if (argv[1] == NULL) { \& printf("Usage: mdtest digestname\en"); \& exit(1); \& } \& \& md = EVP_get_digestbyname(argv[1]); \& if (md == NULL) { \& printf("Unknown message digest %s\en", argv[1]); \& exit(1); \& } \& \& mdctx = EVP_MD_CTX_new(); \& EVP_DigestInit_ex(mdctx, md, NULL); \& EVP_DigestUpdate(mdctx, mess1, strlen(mess1)); \& EVP_DigestUpdate(mdctx, mess2, strlen(mess2)); \& EVP_DigestFinal_ex(mdctx, md_value, &md_len); \& EVP_MD_CTX_free(mdctx); \& \& printf("Digest is: "); \& for (i = 0; i < md_len; i++) \& printf("%02x", md_value[i]); \& printf("\en"); \& \& exit(0); \& } .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_MD_meth_new\fR\|(3), \&\fBdgst\fR\|(1), \&\fBevp\fR\|(7) .PP The full list of digest algorithms are provided below. .PP \&\fBEVP_blake2b512\fR\|(3), \&\fBEVP_md2\fR\|(3), \&\fBEVP_md4\fR\|(3), \&\fBEVP_md5\fR\|(3), \&\fBEVP_mdc2\fR\|(3), \&\fBEVP_ripemd160\fR\|(3), \&\fBEVP_sha1\fR\|(3), \&\fBEVP_sha224\fR\|(3), \&\fBEVP_sha3_224\fR\|(3), \&\fBEVP_sm3\fR\|(3), \&\fBEVP_whirlpool\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The \fBEVP_MD_CTX_create()\fR and \fBEVP_MD_CTX_destroy()\fR functions were renamed to \&\fBEVP_MD_CTX_new()\fR and \fBEVP_MD_CTX_free()\fR in OpenSSL 1.1.0, respectively. .PP The link between digests and signing algorithms was fixed in OpenSSL 1.0 and later, so now \fBEVP_sha1()\fR can be used with \s-1RSA\s0 and \s-1DSA.\s0 .PP The \fBEVP_dss1()\fR function was removed in OpenSSL 1.1.0. .PP The \fBEVP_MD_CTX_set_pkey_ctx()\fR function was added in 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

The primary documented use is with \fBEVP_SignFinal\fR\|(3) and \&\fBEVP_SealInit\fR\|(3), but it isn't limited there. The returned size is also large enough for the output buffer of \fBEVP_PKEY_sign\fR\|(3), \&\fBEVP_PKEY_encrypt\fR\|(3), \fBEVP_PKEY_decrypt\fR\|(3), \fBEVP_PKEY_derive\fR\|(3). .PP It must be stressed that, unless the documentation for the operation that's being performed says otherwise, the size returned by \&\fBEVP_PKEY_size()\fR is only preliminary and not exact, so the final contents of the target buffer may be smaller. It is therefore crucial to take note of the size given back by the function that performs the operation, such as \fBEVP_PKEY_sign\fR\|(3) (the \fIsiglen\fR argument will receive that length), to avoid bugs. .PP \&\fBEVP_PKEY_bits()\fR returns the cryptographic length of the cryptosystem to which the key in \fIpkey\fR belongs, in bits. Note that the definition of cryptographic length is specific to the key cryptosystem. .PP \&\fBEVP_PKEY_security_bits()\fR returns the number of security bits of the given \&\fIpkey\fR, bits of security is defined in \s-1NIST SP800\-57.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_PKEY_size()\fR, \fBEVP_PKEY_bits()\fR and \fBEVP_PKEY_security_bits()\fR return a positive number, or 0 if this size isn't available. .SH "NOTES" .IX Header "NOTES" Most functions that have an output buffer and are mentioned with \&\fBEVP_PKEY_size()\fR have a functionality where you can pass \s-1NULL\s0 for the buffer and still pass a pointer to an integer and get the exact size that this function call delivers in the context that it's called in. This allows those functions to be called twice, once to find out the exact buffer size, then allocate the buffer in between, and call that function again actually output the data. For those functions, it isn't strictly necessary to call \fBEVP_PKEY_size()\fR to find out the buffer size, but may be useful in cases where it's desirable to know the upper limit in advance. .PP It should also be especially noted that \fBEVP_PKEY_size()\fR shouldn't be used to get the output size for \fBEVP_DigestSignFinal()\fR, according to \&\*(L"\s-1NOTES\*(R"\s0 in \fBEVP_DigestSignFinal\fR\|(3). .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_SignFinal\fR\|(3), \&\fBEVP_SealInit\fR\|(3), \&\fBEVP_PKEY_sign\fR\|(3), \&\fBEVP_PKEY_encrypt\fR\|(3), \&\fBEVP_PKEY_decrypt\fR\|(3), \&\fBEVP_PKEY_derive\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2020 The OpenSSL Project Authors.

So any list of \s-1CA\s0 names set is never sent from client to server and the list of \s-1CA\s0 names retrieved by \fBSSL_get0_peer_CA_list()\fR is always \fB\s-1NULL\s0\fR. .PP For \s-1TLS 1.3\s0 the list of \s-1CA\s0 names is sent using the \fBcertificate_authorities\fR extension and may be sent by a client (in the ClientHello message) or by a server (when requesting a certificate). .PP In most cases it is not necessary to set \s-1CA\s0 names on the client side. The list of \s-1CA\s0 names that are acceptable to the client will be sent in plaintext to the server. This has privacy implications and may also have performance implications if the list is large. This optional capability was introduced as part of TLSv1.3 and therefore setting \s-1CA\s0 names on the client side will have no impact if that protocol version has been disabled. Most servers do not need this and so this should be avoided unless required. .PP The \*(L"client \s-1CA\s0 list\*(R" functions below only have an effect when called on the server side. .PP \&\fBSSL_CTX_set_client_CA_list()\fR sets the \fBlist\fR of CAs sent to the client when requesting a client certificate for \fBctx\fR. Ownership of \fBlist\fR is transferred to \fBctx\fR and it should not be freed by the caller. .PP \&\fBSSL_set_client_CA_list()\fR sets the \fBlist\fR of CAs sent to the client when requesting a client certificate for the chosen \fBssl\fR, overriding the setting valid for \fBssl\fR's \s-1SSL_CTX\s0 object. Ownership of \fBlist\fR is transferred to \fBs\fR and it should not be freed by the caller. .PP \&\fBSSL_CTX_get_client_CA_list()\fR returns the list of client CAs explicitly set for \&\fBctx\fR using \fBSSL_CTX_set_client_CA_list()\fR. The returned list should not be freed by the caller. .PP \&\fBSSL_get_client_CA_list()\fR returns the list of client CAs explicitly set for \fBssl\fR using \fBSSL_set_client_CA_list()\fR or \fBssl\fR's \s-1SSL_CTX\s0 object with \&\fBSSL_CTX_set_client_CA_list()\fR, when in server mode. In client mode, SSL_get_client_CA_list returns the list of client CAs sent from the server, if any. The returned list should not be freed by the caller. .PP \&\fBSSL_CTX_add_client_CA()\fR adds the \s-1CA\s0 name extracted from \fBcacert\fR to the list of CAs sent to the client when requesting a client certificate for \&\fBctx\fR. .PP \&\fBSSL_add_client_CA()\fR adds the \s-1CA\s0 name extracted from \fBcacert\fR to the list of CAs sent to the client when requesting a client certificate for the chosen \fBssl\fR, overriding the setting valid for \fBssl\fR's \s-1SSL_CTX\s0 object. .PP \&\fBSSL_get0_peer_CA_list()\fR retrieves the list of \s-1CA\s0 names (if any) the peer has sent. This can be called on either the server or the client side. The returned list should not be freed by the caller. .PP The \*(L"generic \s-1CA\s0 list\*(R" functions below are very similar to the \*(L"client \s-1CA\s0 list\*(R" functions except that they have an effect on both the server and client sides. The lists of \s-1CA\s0 names managed are separate \- so you cannot (for example) set \s-1CA\s0 names using the \*(L"client \s-1CA\s0 list\*(R" functions and then get them using the \&\*(L"generic \s-1CA\s0 list\*(R" functions. Where a mix of the two types of functions has been used on the server side then the \*(L"client \s-1CA\s0 list\*(R" functions take precedence. Typically, on the server side, the \*(L"client \s-1CA\s0 list \*(R" functions should be used in preference. As noted above in most cases it is not necessary to set \s-1CA\s0 names on the client side. .PP \&\fBSSL_CTX_set0_CA_list()\fR sets the list of CAs to be sent to the peer to \&\fBname_list\fR. Ownership of \fBname_list\fR is transferred to \fBctx\fR and it should not be freed by the caller. .PP \&\fBSSL_set0_CA_list()\fR sets the list of CAs to be sent to the peer to \fBname_list\fR overriding any list set in the parent \fB\s-1SSL_CTX\s0\fR of \fBs\fR. Ownership of \&\fBname_list\fR is transferred to \fBs\fR and it should not be freed by the caller. .PP \&\fBSSL_CTX_get0_CA_list()\fR retrieves any previously set list of CAs set for \&\fBctx\fR. The returned list should not be freed by the caller. .PP \&\fBSSL_get0_CA_list()\fR retrieves any previously set list of CAs set for \&\fBs\fR or if none are set the list from the parent \fB\s-1SSL_CTX\s0\fR is retrieved. The returned list should not be freed by the caller. .PP \&\fBSSL_CTX_add1_to_CA_list()\fR appends the \s-1CA\s0 subject name extracted from \fBx\fR to the list of CAs sent to peer for \fBctx\fR. .PP \&\fBSSL_add1_to_CA_list()\fR appends the \s-1CA\s0 subject name extracted from \fBx\fR to the list of CAs sent to the peer for \fBs\fR, overriding the setting in the parent \&\fB\s-1SSL_CTX\s0\fR. .SH "NOTES" .IX Header "NOTES" When a \s-1TLS/SSL\s0 server requests a client certificate (see \&\fB\fBSSL_CTX_set_verify\fB\|(3)\fR), it sends a list of CAs, for which it will accept certificates, to the client. .PP This list must explicitly be set using \fBSSL_CTX_set_client_CA_list()\fR or \&\fBSSL_CTX_set0_CA_list()\fR for \fBctx\fR and \fBSSL_set_client_CA_list()\fR or \&\fBSSL_set0_CA_list()\fR for the specific \fBssl\fR. The list specified overrides the previous setting.

It will normally be set to \s-1NULL.\s0 .SH "NOTES" .IX Header "NOTES" Although the recipients certificate is not needed to decrypt the data it is needed to locate the appropriate (of possible several) recipients in the \s-1CMS\s0 structure. .PP If \fBcert\fR is set to \s-1NULL\s0 all possible recipients are tried. This case however is problematic. To thwart the \s-1MMA\s0 attack (Bleichenbacher's attack on \&\s-1PKCS\s0 #1 v1.5 \s-1RSA\s0 padding) all recipients are tried whether they succeed or not. If no recipient succeeds then a random symmetric key is used to decrypt the content: this will typically output garbage and may (but is not guaranteed to) ultimately return a padding error only. If \fBCMS_decrypt()\fR just returned an error when all recipient encrypted keys failed to decrypt an attacker could use this in a timing attack. If the special flag \fB\s-1CMS_DEBUG_DECRYPT\s0\fR is set then the above behaviour is modified and an error \fBis\fR returned if no recipient encrypted key can be decrypted \fBwithout\fR generating a random content encryption key. Applications should use this flag with \&\fBextreme caution\fR especially in automated gateways as it can leave them open to attack. .PP It is possible to determine the correct recipient key by other means (for example looking them up in a database) and setting them in the \s-1CMS\s0 structure in advance using the \s-1CMS\s0 utility functions such as \fBCMS_set1_pkey()\fR.

The time setting functions obey the rules outlined in \s-1RFC5280:\s0 if the date can be represented by UTCTime it is used, else GeneralizedTime is used. .PP The \s-1ASN1_TIME, ASN1_UTCTIME\s0 and \s-1ASN1_GENERALIZEDTIME\s0 structures are represented as an \s-1ASN1_STRING\s0 internally and can be freed up using \fBASN1_STRING_free()\fR. .PP The \s-1ASN1_TIME\s0 structure can represent years from 0000 to 9999 but no attempt is made to correct ancient calendar changes (for example from Julian to Gregorian calendars). .PP \&\s-1ASN1_UTCTIME\s0 is limited to a year range of 1950 through 2049. .PP Some applications add offset times directly to a time_t value and pass the results to \fBASN1_TIME_set()\fR (or equivalent). This can cause problems as the time_t value can overflow on some systems resulting in unexpected results. New applications should use \fBASN1_TIME_adj()\fR instead and pass the offset value in the \fBoffset_sec\fR and \fBoffset_day\fR parameters instead of directly manipulating a time_t value. .PP \&\fBASN1_TIME_adj()\fR may change the type from \s-1ASN1_GENERALIZEDTIME\s0 to \s-1ASN1_UTCTIME,\s0 or vice versa, based on the resulting year. The \fBASN1_GENERALIZEDTIME_adj()\fR and \&\fBASN1_UTCTIME_adj()\fR functions will not modify the type of the return structure. .PP It is recommended that functions starting with \s-1ASN1_TIME\s0 be used instead of those starting with \s-1ASN1_UTCTIME\s0 or \s-1ASN1_GENERALIZEDTIME.\s0 The functions starting with \s-1ASN1_UTCTIME\s0 and \s-1ASN1_GENERALIZEDTIME\s0 act only on that specific time format. The functions starting with \s-1ASN1_TIME\s0 will operate on either format. .SH "BUGS" .IX Header "BUGS" \&\fBASN1_TIME_print()\fR, \fBASN1_UTCTIME_print()\fR and \fBASN1_GENERALIZEDTIME_print()\fR do not print out the timezone: it either prints out \*(L"\s-1GMT\*(R"\s0 or nothing.

A new \s-1EC_KEY\s0 with no associated curve can be constructed by calling \&\fBEC_KEY_new()\fR. The reference count for the newly created \s-1EC_KEY\s0 is initially set to 1. A curve can be associated with the \s-1EC_KEY\s0 by calling \&\fBEC_KEY_set_group()\fR. .PP Alternatively a new \s-1EC_KEY\s0 can be constructed by calling \&\fBEC_KEY_new_by_curve_name()\fR and supplying the nid of the associated curve. See \&\fBEC_GROUP_new\fR\|(3) for a description of curve names. This function simply wraps calls to \fBEC_KEY_new()\fR and \fBEC_GROUP_new_by_curve_name()\fR. .PP Calling \fBEC_KEY_free()\fR decrements the reference count for the \s-1EC_KEY\s0 object, and if it has dropped to zero then frees the memory associated with it. If \&\fBkey\fR is \s-1NULL\s0 nothing is done. .PP \&\fBEC_KEY_copy()\fR copies the contents of the \s-1EC_KEY\s0 in \fBsrc\fR into \fBdest\fR. .PP \&\fBEC_KEY_dup()\fR creates a new \s-1EC_KEY\s0 object and copies \fBec_key\fR into it. .PP \&\fBEC_KEY_up_ref()\fR increments the reference count associated with the \s-1EC_KEY\s0 object. .PP \&\fBEC_KEY_get0_engine()\fR returns a handle to the \s-1ENGINE\s0 that has been set for this \s-1EC_KEY\s0 object. .PP \&\fBEC_KEY_generate_key()\fR generates a new public and private key for the supplied \&\fBeckey\fR object. \fBeckey\fR must have an \s-1EC_GROUP\s0 object associated with it before calling this function. The private key is a random integer (0 < priv_key < order, where \fIorder\fR is the order of the \s-1EC_GROUP\s0 object). The public key is an \s-1EC_POINT\s0 on the curve calculated by multiplying the generator for the curve by the private key. .PP \&\fBEC_KEY_check_key()\fR performs various sanity checks on the \s-1EC_KEY\s0 object to confirm that it is valid. .PP \&\fBEC_KEY_set_public_key_affine_coordinates()\fR sets the public key for \fBkey\fR based on its affine co-ordinates; i.e., it constructs an \s-1EC_POINT\s0 object based on the supplied \fBx\fR and \fBy\fR values and sets the public key to be this \&\s-1EC_POINT.\s0 It also performs certain sanity checks on the key to confirm that it is valid. .PP The functions \fBEC_KEY_get0_group()\fR, \fBEC_KEY_set_group()\fR, \&\fBEC_KEY_get0_private_key()\fR, \fBEC_KEY_set_private_key()\fR, \fBEC_KEY_get0_public_key()\fR, and \fBEC_KEY_set_public_key()\fR get and set the \s-1EC_GROUP\s0 object, the private key, and the \s-1EC_POINT\s0 public key for the \fBkey\fR respectively. The function \&\fBEC_KEY_set_private_key()\fR accepts \s-1NULL\s0 as the priv_key argument to securely clear the private key component from the \s-1EC_KEY.\s0 .PP The functions \fBEC_KEY_get_conv_form()\fR and \fBEC_KEY_set_conv_form()\fR get and set the point_conversion_form for the \fBkey\fR. For a description of point_conversion_forms please see \fBEC_POINT_new\fR\|(3). .PP \&\fBEC_KEY_set_flags()\fR sets the flags in the \fBflags\fR parameter on the \s-1EC_KEY\s0 object. Any flags that are already set are left set. The flags currently defined are \s-1EC_FLAG_NON_FIPS_ALLOW\s0 and \s-1EC_FLAG_FIPS_CHECKED.\s0 In addition there is the flag \s-1EC_FLAG_COFACTOR_ECDH\s0 which is specific to \s-1ECDH.\s0 \&\fBEC_KEY_get_flags()\fR returns the current flags that are set for this \s-1EC_KEY.\s0 \&\fBEC_KEY_clear_flags()\fR clears the flags indicated by the \fBflags\fR parameter; all other flags are left in their existing state. .PP \&\fBEC_KEY_set_asn1_flag()\fR sets the asn1_flag on the underlying \s-1EC_GROUP\s0 object (if set). Refer to \fBEC_GROUP_copy\fR\|(3) for further information on the asn1_flag. .PP \&\fBEC_KEY_decoded_from_explicit_params()\fR returns 1 if the group of the \fIkey\fR was decoded from data with explicitly encoded group parameters, \-1 if the \fIkey\fR is \s-1NULL\s0 or the group parameters are missing, and 0 otherwise. .PP \&\fBEC_KEY_precompute_mult()\fR stores multiples of the underlying \s-1EC_GROUP\s0 generator for faster point multiplication. See also \fBEC_POINT_add\fR\|(3). .PP \&\fBEC_KEY_oct2key()\fR and \fBEC_KEY_key2buf()\fR are identical to the functions \&\fBEC_POINT_oct2point()\fR and \fBEC_POINT_point2buf()\fR except they use the public key \&\s-1EC_POINT\s0 in \fBeckey\fR. .PP \&\fBEC_KEY_oct2priv()\fR and \fBEC_KEY_priv2oct()\fR convert between the private key component of \fBeckey\fR and octet form. The octet form consists of the content octets of the \fBprivateKey\fR \s-1OCTET STRING\s0 in an \fBECPrivateKey\fR \s-1ASN.1\s0 structure. .PP The function \fBEC_KEY_priv2oct()\fR must be supplied with a buffer long enough to store the octet form. The return value provides the number of octets stored. Calling the function with a \s-1NULL\s0 buffer will not perform the conversion but will just return the required buffer length. .PP The function \fBEC_KEY_priv2buf()\fR allocates a buffer of suitable length and writes an \s-1EC_KEY\s0 to it in octet format. The allocated buffer is written to \fB*pbuf\fR and its length is returned. The caller must free up the allocated buffer with a call to \fBOPENSSL_free()\fR. Since the allocated buffer value is written to \fB*pbuf\fR the \fBpbuf\fR parameter \fB\s-1MUST NOT\s0\fR be \fB\s-1NULL\s0\fR. .PP \&\fBEC_KEY_priv2buf()\fR converts an \s-1EC_KEY\s0 private key into an allocated buffer. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEC_KEY_new()\fR, \fBEC_KEY_new_by_curve_name()\fR and \fBEC_KEY_dup()\fR return a pointer to the newly created \s-1EC_KEY\s0 object, or \s-1NULL\s0 on error. .PP \&\fBEC_KEY_get_flags()\fR returns the flags associated with the \s-1EC_KEY\s0 object as an integer. .PP \&\fBEC_KEY_copy()\fR returns a pointer to the destination key, or \s-1NULL\s0 on error. .PP \&\fBEC_KEY_get0_engine()\fR returns a pointer to an \s-1ENGINE,\s0 or \s-1NULL\s0 if it wasn't set. .PP \&\fBEC_KEY_up_ref()\fR, \fBEC_KEY_set_group()\fR, \fBEC_KEY_set_public_key()\fR, \&\fBEC_KEY_precompute_mult()\fR, \fBEC_KEY_generate_key()\fR, \fBEC_KEY_check_key()\fR, \&\fBEC_KEY_set_public_key_affine_coordinates()\fR, \fBEC_KEY_oct2key()\fR and \&\fBEC_KEY_oct2priv()\fR return 1 on success or 0 on error. .PP \&\fBEC_KEY_set_private_key()\fR returns 1 on success or 0 on error except when the priv_key argument is \s-1NULL,\s0 in that case it returns 0, for legacy compatibility, and should not be treated as an error. .PP \&\fBEC_KEY_get0_group()\fR returns the \s-1EC_GROUP\s0 associated with the \s-1EC_KEY.\s0 .PP \&\fBEC_KEY_get0_private_key()\fR returns the private key associated with the \s-1EC_KEY.\s0 .PP \&\fBEC_KEY_get_conv_form()\fR return the point_conversion_form for the \s-1EC_KEY.\s0 .PP \&\fBEC_KEY_key2buf()\fR, \fBEC_KEY_priv2oct()\fR and \fBEC_KEY_priv2buf()\fR return the length of the buffer or 0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBcrypto\fR\|(7), \fBEC_GROUP_new\fR\|(3), \&\fBEC_GROUP_copy\fR\|(3), \fBEC_POINT_new\fR\|(3), \&\fBEC_POINT_add\fR\|(3), \&\fBEC_GFp_simple_method\fR\|(3), \&\fBd2i_ECPKParameters\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2013\-2022 The OpenSSL Project Authors.

If this is the case, the \s-1DRBG\s0 reseeds automatically. Additionally, an immediate reseeding can be requested by setting the \&\fBprediction_resistance\fR flag to 1. See \s-1NOTES\s0 section for more details. .PP The caller can optionally provide additional data to be used for reseeding by passing a pointer \fBadin\fR to a buffer of length \fBadinlen\fR.

Additionally some resources are allocated on a per thread basis (if the application is multi-threaded), and these resources must be freed prior to the thread closing. .PP As of version 1.1.0 OpenSSL will automatically allocate all resources that it needs so no explicit initialisation is required. Similarly it will also automatically deinitialise as required. .PP However, there may be situations when explicit initialisation is desirable or needed, for example when some nondefault initialisation is required. The function \fBOPENSSL_init_crypto()\fR can be used for this purpose for libcrypto (see also \fBOPENSSL_init_ssl\fR\|(3) for the libssl equivalent). .PP Numerous internal OpenSSL functions call \fBOPENSSL_init_crypto()\fR.

This not a default option. .IP "\s-1OPENSSL_INIT_ATFORK\s0" 4 .IX Item "OPENSSL_INIT_ATFORK" With this option the library will register its fork handlers. See \fBOPENSSL_fork_prepare\fR\|(3) for details. .IP "\s-1OPENSSL_INIT_NO_ATEXIT\s0" 4 .IX Item "OPENSSL_INIT_NO_ATEXIT" By default OpenSSL will attempt to clean itself up when the process exits via an \&\*(L"atexit\*(R" handler. Using this option suppresses that behaviour. This means that the application will have to clean up OpenSSL explicitly using \&\fBOPENSSL_cleanup()\fR. .PP Multiple options may be combined together in a single call to \&\fBOPENSSL_init_crypto()\fR. For example: .PP .Vb 2 \& OPENSSL_init_crypto(OPENSSL_INIT_NO_ADD_ALL_CIPHERS \& | OPENSSL_INIT_NO_ADD_ALL_DIGESTS, NULL); .Ve .PP The \fBOPENSSL_cleanup()\fR function deinitialises OpenSSL (both libcrypto and libssl). All resources allocated by OpenSSL are freed. Typically there should be no need to call this function directly as it is initiated automatically on application exit. This is done via the standard C library \&\fBatexit()\fR function. In the event that the application will close in a manner that will not call the registered \fBatexit()\fR handlers then the application should call \fBOPENSSL_cleanup()\fR directly. Developers of libraries using OpenSSL are discouraged from calling this function and should instead, typically, rely on auto-deinitialisation. This is to avoid error conditions where both an application and a library it depends on both use OpenSSL, and the library deinitialises it before the application has finished using it. .PP Once \fBOPENSSL_cleanup()\fR has been called the library cannot be reinitialised. Attempts to call \fBOPENSSL_init_crypto()\fR will fail and an \s-1ERR_R_INIT_FAIL\s0 error will be added to the error stack. Note that because initialisation has failed OpenSSL error strings will not be available, only an error code. This code can be put through the openssl errstr command line application to produce a human readable error (see \fBerrstr\fR\|(1)). .PP The \fBOPENSSL_atexit()\fR function enables the registration of a function to be called during \fBOPENSSL_cleanup()\fR. Stop handlers are called after deinitialisation of resources local to a thread, but before other process wide resources are freed. In the event that multiple stop handlers are registered, no guarantees are made about the order of execution. .PP The \fBOPENSSL_thread_stop()\fR function deallocates resources associated with the current thread. Typically this function will be called automatically by the library when the thread exits. This should only be called directly if resources should be freed at an earlier time, or under the circumstances described in the \s-1NOTES\s0 section below. .PP The \fB\s-1OPENSSL_INIT_LOAD_CONFIG\s0\fR flag will load a configuration file, as with \&\fBCONF_modules_load_file\fR\|(3) with \s-1NULL\s0 filename and application name and the \&\fB\s-1CONF_MFLAGS_IGNORE_MISSING_FILE\s0\fR, \fB\s-1CONF_MFLAGS_IGNORE_RETURN_CODES\s0\fR and \&\fB\s-1CONF_MFLAGS_DEFAULT_SECTION\s0\fR flags. The filename, application name, and flags can be customized by providing a non-null \fB\s-1OPENSSL_INIT_SETTINGS\s0\fR object. The object can be allocated via \fB\fBOPENSSL_init_new()\fB\fR. The \fB\fBOPENSSL_INIT_set_config_filename()\fB\fR function can be used to specify a nondefault filename, which is copied and need not refer to persistent storage. Similarly, \fBOPENSSL_INIT_set_config_appname()\fR can be used to specify a nondefault application name. Finally, OPENSSL_INIT_set_file_flags can be used to specify nondefault flags. If the \fB\s-1CONF_MFLAGS_IGNORE_RETURN_CODES\s0\fR flag is not included, any errors in the configuration file will cause an error return from \fBOPENSSL_init_crypto\fR or indirectly \fBOPENSSL_init_ssl\fR\|(3). The object can be released with \fBOPENSSL_INIT_free()\fR when done. .SH "NOTES" .IX Header "NOTES" Resources local to a thread are deallocated automatically when the thread exits (e.g. in a pthreads environment, when \fBpthread_exit()\fR is called). On Windows platforms this is done in response to a \s-1DLL_THREAD_DETACH\s0 message being sent to the libcrypto32.dll entry point. Some windows functions may cause threads to exit without sending this message (for example \fBExitProcess()\fR). If the application uses such functions, then the application must free up OpenSSL resources directly via a call to \fBOPENSSL_thread_stop()\fR on each thread. Similarly this message will also not be sent if OpenSSL is linked statically, and therefore applications using static linking should also call \fBOPENSSL_thread_stop()\fR on each thread. Additionally if OpenSSL is loaded dynamically via \fBLoadLibrary()\fR and the threads are not destroyed until after \fBFreeLibrary()\fR is called then each thread should call \fBOPENSSL_thread_stop()\fR prior to the \fBFreeLibrary()\fR call. .PP On Linux/Unix where OpenSSL has been loaded via \fBdlopen()\fR and the application is multi-threaded and if \fBdlclose()\fR is subsequently called prior to the threads being destroyed then OpenSSL will not be able to deallocate resources associated with those threads. The application should either call \fBOPENSSL_thread_stop()\fR on each thread prior to the \fBdlclose()\fR call, or alternatively the original \fBdlopen()\fR call should use the \s-1RTLD_NODELETE\s0 flag (where available on the platform). .SH "RETURN VALUES" .IX Header "RETURN VALUES" The functions OPENSSL_init_crypto, \fBOPENSSL_atexit()\fR and \&\fBOPENSSL_INIT_set_config_appname()\fR return 1 on success or 0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBOPENSSL_init_ssl\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The \fBOPENSSL_init_crypto()\fR, \fBOPENSSL_cleanup()\fR, \fBOPENSSL_atexit()\fR, \&\fBOPENSSL_thread_stop()\fR, \fBOPENSSL_INIT_new()\fR, \fBOPENSSL_INIT_set_config_appname()\fR and \fBOPENSSL_INIT_free()\fR functions were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2022 The OpenSSL Project Authors.

The list depends on settings like the cipher list, the supported protocol versions, the security level, and the enabled signature algorithms. \&\s-1SRP\s0 and \s-1PSK\s0 ciphers are only enabled if the appropriate callbacks or settings have been applied. The list of ciphers that would be sent in a ClientHello can differ from the list of ciphers that would be acceptable when acting as a server. For example, additional ciphers may be usable by a server if there is a gap in the list of supported protocols, and some ciphers may not be usable by a server if there is not a suitable certificate configured. If \fBssl\fR is \s-1NULL\s0 or no ciphers are available, \s-1NULL\s0 is returned. .PP \&\fBSSL_get_client_ciphers()\fR returns the stack of available SSL_CIPHERs matching the list received from the client on \fBssl\fR.

Returns 1 on success and 0 on failure. .PP \&\fBSSL_get_cipher_list()\fR returns a pointer to the name of the \s-1SSL_CIPHER\s0 listed for \fBssl\fR with \fBpriority\fR. If \fBssl\fR is \s-1NULL,\s0 no ciphers are available, or there are less ciphers than \fBpriority\fR available, \s-1NULL\s0 is returned. .PP \&\fBSSL_get_shared_ciphers()\fR creates a colon separated and \s-1NUL\s0 terminated list of \&\s-1SSL_CIPHER\s0 names that are available in both the client and the server. \fBbuf\fR is the buffer that should be populated with the list of names and \fBsize\fR is the size of that buffer. A pointer to \fBbuf\fR is returned on success or \s-1NULL\s0 on error. If the supplied buffer is not large enough to contain the complete list of names then a truncated list of names will be returned. Note that just because a ciphersuite is available (i.e. it is configured in the cipher list) and shared by both the client and the server it does not mean that it is enabled (see the description of \fBSSL_get1_supported_ciphers()\fR above). This function will return available shared ciphersuites whether or not they are enabled. This is a server side function only and must only be called after the completion of the initial handshake. .SH "NOTES" .IX Header "NOTES" The details of the ciphers obtained by \fBSSL_get_ciphers()\fR, \fBSSL_CTX_get_ciphers()\fR \&\fBSSL_get1_supported_ciphers()\fR and \fBSSL_get_client_ciphers()\fR can be obtained using the \fBSSL_CIPHER_get_name\fR\|(3) family of functions. .PP Call \fBSSL_get_cipher_list()\fR with \fBpriority\fR starting from 0 to obtain the sorted list of available ciphers, until \s-1NULL\s0 is returned. .PP Note: \fBSSL_get_ciphers()\fR, \fBSSL_CTX_get_ciphers()\fR and \fBSSL_get_client_ciphers()\fR return a pointer to an internal cipher stack, which will be freed later on when the \s-1SSL\s0 or \s-1SSL_SESSION\s0 object is freed.

This capability could be utilised to parallelise the processing of a single connection. For example a single write can be split into multiple records and each one encrypted independently and in parallel. Note: this will only work in \&\s-1TLS1.1+.\s0 There is no support in SSLv3, TLSv1.0 or \s-1DTLS\s0 (any version). This capability is known as \*(L"pipelining\*(R" within OpenSSL. .PP In order to benefit from the pipelining capability. You need to have an engine that provides ciphers that support this. The OpenSSL \*(L"dasync\*(R" engine provides \&\s-1AES128\-SHA\s0 based ciphers that have this capability. However, these are for development and test purposes only. .PP \&\fBSSL_CTX_set_max_send_fragment()\fR and \fBSSL_set_max_send_fragment()\fR set the \&\fBmax_send_fragment\fR parameter for \s-1SSL_CTX\s0 and \s-1SSL\s0 objects respectively. This value restricts the amount of plaintext bytes that will be sent in any one \&\s-1SSL/TLS\s0 record. By default its value is \s-1SSL3_RT_MAX_PLAIN_LENGTH\s0 (16384). These functions will only accept a value in the range 512 \- \s-1SSL3_RT_MAX_PLAIN_LENGTH.\s0 .PP \&\fBSSL_CTX_set_max_pipelines()\fR and \fBSSL_set_max_pipelines()\fR set the maximum number of pipelines that will be used at any one time. This value applies to both \&\*(L"read\*(R" pipelining and \*(L"write\*(R" pipelining. By default only one pipeline will be used (i.e. normal non-parallel operation). The number of pipelines set must be in the range 1 \- \s-1SSL_MAX_PIPELINES\s0 (32). Setting this to a value > 1 will also automatically turn on \*(L"read_ahead\*(R" (see \fBSSL_CTX_set_read_ahead\fR\|(3)). This is explained further below. OpenSSL will only every use more than one pipeline if a cipher suite is negotiated that uses a pipeline capable cipher provided by an engine. .PP Pipelining operates slightly differently for reading encrypted data compared to writing encrypted data. \fBSSL_CTX_set_split_send_fragment()\fR and \&\fBSSL_set_split_send_fragment()\fR define how data is split up into pipelines when writing encrypted data. The number of pipelines used will be determined by the amount of data provided to the \fBSSL_write_ex()\fR or \fBSSL_write()\fR call divided by \&\fBsplit_send_fragment\fR. .PP For example if \fBsplit_send_fragment\fR is set to 2000 and \fBmax_pipelines\fR is 4 then: .PP SSL_write/SSL_write_ex called with 0\-2000 bytes == 1 pipeline used .PP SSL_write/SSL_write_ex called with 2001\-4000 bytes == 2 pipelines used .PP SSL_write/SSL_write_ex called with 4001\-6000 bytes == 3 pipelines used .PP SSL_write/SSL_write_ex called with 6001+ bytes == 4 pipelines used .PP \&\fBsplit_send_fragment\fR must always be less than or equal to \&\fBmax_send_fragment\fR. By default it is set to be equal to \fBmax_send_fragment\fR. This will mean that the same number of records will always be created as would have been created in the non-parallel case, although the data will be apportioned differently. In the parallel case data will be spread equally between the pipelines. .PP Read pipelining is controlled in a slightly different way than with write pipelining. While reading we are constrained by the number of records that the peer (and the network) can provide to us in one go. The more records we can get in one go the more opportunity we have to parallelise the processing. As noted above when setting \fBmax_pipelines\fR to a value greater than one, \fBread_ahead\fR is automatically set. The \fBread_ahead\fR parameter causes OpenSSL to attempt to read as much data into the read buffer as the network can provide and will fit into the buffer. Without this set data is read into the read buffer one record at a time. The more data that can be read, the more opportunity there is for parallelising the processing at the cost of increased memory overhead per connection. Setting \fBread_ahead\fR can impact the behaviour of the \fBSSL_pending()\fR function (see \fBSSL_pending\fR\|(3)). .PP The \fBSSL_CTX_set_default_read_buffer_len()\fR and \fBSSL_set_default_read_buffer_len()\fR functions control the size of the read buffer that will be used. The \fBlen\fR parameter sets the size of the buffer. The value will only be used if it is greater than the default that would have been used anyway. The normal default value depends on a number of factors but it will be at least \&\s-1SSL3_RT_MAX_PLAIN_LENGTH + SSL3_RT_MAX_ENCRYPTED_OVERHEAD\s0 (16704) bytes. .PP \&\fBSSL_CTX_set_tlsext_max_fragment_length()\fR sets the default maximum fragment length negotiation mode via value \fBmode\fR to \fBctx\fR. This setting affects only \s-1SSL\s0 instances created after this function is called. It affects the client-side as only its side may initiate this extension use. .PP \&\fBSSL_set_tlsext_max_fragment_length()\fR sets the maximum fragment length negotiation mode via value \fBmode\fR to \fBssl\fR. This setting will be used during a handshake when extensions are exchanged between client and server. So it only affects \s-1SSL\s0 sessions created after this function is called. It affects the client-side as only its side may initiate this extension use. .PP \&\fBSSL_SESSION_get_max_fragment_length()\fR gets the maximum fragment length negotiated in \fBsession\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" All non-void functions return 1 on success and 0 on failure. .SH "NOTES" .IX Header "NOTES" The Maximum Fragment Length extension support is optional on the server side. If the server does not support this extension then \&\fBSSL_SESSION_get_max_fragment_length()\fR will return: TLSEXT_max_fragment_length_DISABLED. .PP The following modes are available: .IP "TLSEXT_max_fragment_length_DISABLED" 4 .IX Item "TLSEXT_max_fragment_length_DISABLED" Disables Maximum Fragment Length Negotiation (default). .IP "TLSEXT_max_fragment_length_512" 4 .IX Item "TLSEXT_max_fragment_length_512" Sets Maximum Fragment Length to 512 bytes. .IP "TLSEXT_max_fragment_length_1024" 4 .IX Item "TLSEXT_max_fragment_length_1024" Sets Maximum Fragment Length to 1024. .IP "TLSEXT_max_fragment_length_2048" 4 .IX Item "TLSEXT_max_fragment_length_2048" Sets Maximum Fragment Length to 2048. .IP "TLSEXT_max_fragment_length_4096" 4 .IX Item "TLSEXT_max_fragment_length_4096" Sets Maximum Fragment Length to 4096. .PP With the exception of \fBSSL_CTX_set_default_read_buffer_len()\fR \&\fBSSL_set_default_read_buffer_len()\fR, \fBSSL_CTX_set_tlsext_max_fragment_length()\fR, \&\fBSSL_set_tlsext_max_fragment_length()\fR and \fBSSL_SESSION_get_max_fragment_length()\fR all these functions are implemented using macros. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CTX_set_read_ahead\fR\|(3), \fBSSL_pending\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The \fBSSL_CTX_set_max_pipelines()\fR, \fBSSL_set_max_pipelines()\fR, \&\fBSSL_CTX_set_split_send_fragment()\fR, \fBSSL_set_split_send_fragment()\fR, \&\fBSSL_CTX_set_default_read_buffer_len()\fR and \fBSSL_set_default_read_buffer_len()\fR functions were added in OpenSSL 1.1.0. .PP The \fBSSL_CTX_set_tlsext_max_fragment_length()\fR, \fBSSL_set_tlsext_max_fragment_length()\fR and \fBSSL_SESSION_get_max_fragment_length()\fR functions were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2020 The OpenSSL Project Authors.

It is a good idea to review the code and see if it addresses your threat model and concerns. .PP If a secure heap is used, then private key \fB\s-1BIGNUM\s0\fR values are stored there. This protects long-term storage of private keys, but will not necessarily put all intermediate values and computations there. .PP \&\fBCRYPTO_secure_malloc_init()\fR creates the secure heap, with the specified \&\f(CW\*(C`size\*(C'\fR in bytes. The \f(CW\*(C`minsize\*(C'\fR parameter is the minimum size to allocate from the heap. Both \f(CW\*(C`size\*(C'\fR and \f(CW\*(C`minsize\*(C'\fR must be a power of two. .PP \&\fBCRYPTO_secure_malloc_initialized()\fR indicates whether or not the secure heap as been initialized and is available. .PP \&\fBCRYPTO_secure_malloc_done()\fR releases the heap and makes the memory unavailable to the process if all secure memory has been freed. It can take noticeably long to complete. .PP \&\fBOPENSSL_secure_malloc()\fR allocates \f(CW\*(C`num\*(C'\fR bytes from the heap. If \fBCRYPTO_secure_malloc_init()\fR is not called, this is equivalent to calling \fBOPENSSL_malloc()\fR. It is a macro that expands to \&\fBCRYPTO_secure_malloc()\fR and adds the \f(CW\*(C`_\|_FILE_\|_\*(C'\fR and \f(CW\*(C`_\|_LINE_\|_\*(C'\fR parameters. .PP \&\fBOPENSSL_secure_zalloc()\fR and \fBCRYPTO_secure_zalloc()\fR are like \&\fBOPENSSL_secure_malloc()\fR and \fBCRYPTO_secure_malloc()\fR, respectively, except that they call \fBmemset()\fR to zero the memory before returning. .PP \&\fBOPENSSL_secure_free()\fR releases the memory at \f(CW\*(C`ptr\*(C'\fR back to the heap.

This is a filter \s-1BIO\s0 which is a wrapper round the OpenSSL \s-1SSL\s0 routines adding a \s-1BIO\s0 \*(L"flavour\*(R" to \&\s-1SSL I/O.\s0 .PP I/O performed on an \s-1SSL BIO\s0 communicates using the \s-1SSL\s0 protocol with the SSLs read and write BIOs. If an \s-1SSL\s0 connection is not established then an attempt is made to establish one on the first I/O call. .PP If a \s-1BIO\s0 is appended to an \s-1SSL BIO\s0 using \fBBIO_push()\fR it is automatically used as the \s-1SSL\s0 BIOs read and write BIOs. .PP Calling \fBBIO_reset()\fR on an \s-1SSL BIO\s0 closes down any current \s-1SSL\s0 connection by calling \fBSSL_shutdown()\fR. \fBBIO_reset()\fR is then sent to the next \s-1BIO\s0 in the chain: this will typically disconnect the underlying transport. The \s-1SSL BIO\s0 is then reset to the initial accept or connect state. .PP If the close flag is set when an \s-1SSL BIO\s0 is freed then the internal \&\s-1SSL\s0 structure is also freed using \fBSSL_free()\fR. .PP \&\fBBIO_set_ssl()\fR sets the internal \s-1SSL\s0 pointer of \s-1SSL BIO\s0 \fBb\fR to \fBssl\fR using the close flag \fBc\fR. .PP \&\fBBIO_get_ssl()\fR retrieves the \s-1SSL\s0 pointer of \s-1SSL BIO\s0 \fBb\fR, it can then be manipulated using the standard \s-1SSL\s0 library functions. .PP \&\fBBIO_set_ssl_mode()\fR sets the \s-1SSL BIO\s0 mode to \fBclient\fR. If \fBclient\fR is 1 client mode is set. If \fBclient\fR is 0 server mode is set. .PP \&\fBBIO_set_ssl_renegotiate_bytes()\fR sets the renegotiate byte count of \s-1SSL BIO\s0 \fBb\fR to \fBnum\fR. When set after every \fBnum\fR bytes of I/O (read and write) the \s-1SSL\s0 session is automatically renegotiated. \fBnum\fR must be at least 512 bytes. .PP \&\fBBIO_set_ssl_renegotiate_timeout()\fR sets the renegotiate timeout of \s-1SSL BIO\s0 \fBb\fR to \fBseconds\fR. When the renegotiate timeout elapses the session is automatically renegotiated. .PP \&\fBBIO_get_num_renegotiates()\fR returns the total number of session renegotiations due to I/O or timeout of \s-1SSL BIO\s0 \fBb\fR. .PP \&\fBBIO_new_ssl()\fR allocates an \s-1SSL BIO\s0 using \s-1SSL_CTX\s0 \fBctx\fR and using client mode if \fBclient\fR is non zero. .PP \&\fBBIO_new_ssl_connect()\fR creates a new \s-1BIO\s0 chain consisting of an \&\s-1SSL BIO\s0 (using \fBctx\fR) followed by a connect \s-1BIO.\s0 .PP \&\fBBIO_new_buffer_ssl_connect()\fR creates a new \s-1BIO\s0 chain consisting of a buffering \s-1BIO,\s0 an \s-1SSL BIO\s0 (using \fBctx\fR), and a connect \s-1BIO.\s0 .PP \&\fBBIO_ssl_copy_session_id()\fR copies an \s-1SSL\s0 session id between \&\s-1BIO\s0 chains \fBfrom\fR and \fBto\fR. It does this by locating the \&\s-1SSL\s0 BIOs in each chain and calling \fBSSL_copy_session_id()\fR on the internal \s-1SSL\s0 pointer. .PP \&\fBBIO_ssl_shutdown()\fR closes down an \s-1SSL\s0 connection on \s-1BIO\s0 chain \fBbio\fR. It does this by locating the \s-1SSL BIO\s0 in the chain and calling \fBSSL_shutdown()\fR on its internal \s-1SSL\s0 pointer. .PP \&\fBBIO_do_handshake()\fR attempts to complete an \s-1SSL\s0 handshake on the supplied \s-1BIO\s0 and establish the \s-1SSL\s0 connection. It returns 1 if the connection was established successfully. A zero or negative value is returned if the connection could not be established, the call \fBBIO_should_retry()\fR should be used for non blocking connect BIOs to determine if the call should be retried. If an \s-1SSL\s0 connection has already been established this call has no effect. .SH "NOTES" .IX Header "NOTES" \&\s-1SSL\s0 BIOs are exceptional in that if the underlying transport is non blocking they can still request a retry in exceptional circumstances. Specifically this will happen if a session renegotiation takes place during a \fBBIO_read_ex()\fR operation, one case where this happens is when step up occurs. .PP The \s-1SSL\s0 flag \s-1SSL_AUTO_RETRY\s0 can be set to disable this behaviour. That is when this flag is set an \s-1SSL BIO\s0 using a blocking transport will never request a retry. .PP Since unknown \fBBIO_ctrl()\fR operations are sent through filter BIOs the servers name and port can be set using \fBBIO_set_host()\fR on the \s-1BIO\s0 returned by \fBBIO_new_ssl_connect()\fR without having to locate the connect \s-1BIO\s0 first. .PP Applications do not have to call \fBBIO_do_handshake()\fR but may wish to do so to separate the handshake process from other I/O processing. .PP \&\fBBIO_set_ssl()\fR, \fBBIO_get_ssl()\fR, \fBBIO_set_ssl_mode()\fR, \&\fBBIO_set_ssl_renegotiate_bytes()\fR, \fBBIO_set_ssl_renegotiate_timeout()\fR, \&\fBBIO_get_num_renegotiates()\fR, and \fBBIO_do_handshake()\fR are implemented as macros. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_f_ssl()\fR returns the \s-1SSL\s0 \fB\s-1BIO_METHOD\s0\fR structure. .PP \&\fBBIO_set_ssl()\fR, \fBBIO_get_ssl()\fR, \fBBIO_set_ssl_mode()\fR, \fBBIO_set_ssl_renegotiate_bytes()\fR, \&\fBBIO_set_ssl_renegotiate_timeout()\fR and \fBBIO_get_num_renegotiates()\fR return 1 on success or a value which is less than or equal to 0 if an error occurred. .PP \&\fBBIO_new_ssl()\fR, \fBBIO_new_ssl_connect()\fR and \fBBIO_new_buffer_ssl_connect()\fR return a valid \fB\s-1BIO\s0\fR structure on success or \fB\s-1NULL\s0\fR if an error occurred. .PP \&\fBBIO_ssl_copy_session_id()\fR returns 1 on success or 0 on error. .PP \&\fBBIO_do_handshake()\fR returns 1 if the connection was established successfully. A zero or negative value is returned if the connection could not be established. .SH "EXAMPLES" .IX Header "EXAMPLES" This \s-1SSL/TLS\s0 client example attempts to retrieve a page from an \&\s-1SSL/TLS\s0 web server.

This is used by the \s-1PEM\s0 routines to read \*(L"\s-1TRUSTED CERTIFICATE\*(R"\s0 objects. This function should not be called on untrusted input. .PP \&\fBi2d_X509_AUX()\fR is similar to \fBi2d_X509\fR\|(3), but the encoded output contains both the certificate and any auxiliary trust information. This is used by the \s-1PEM\s0 routines to write \*(L"\s-1TRUSTED CERTIFICATE\*(R"\s0 objects. Note that this is a non-standard OpenSSL-specific data format. .PP \&\fBi2d_re_X509_tbs()\fR is similar to \fBi2d_X509\fR\|(3) except it encodes only the TBSCertificate portion of the certificate. \fBi2d_re_X509_CRL_tbs()\fR and \fBi2d_re_X509_REQ_tbs()\fR are analogous for \s-1CRL\s0 and certificate request, respectively. The \*(L"re\*(R" in \fBi2d_re_X509_tbs\fR stands for \*(L"re-encode\*(R", and ensures that a fresh encoding is generated in case the object has been modified after creation (see the \s-1BUGS\s0 section). .PP The encoding of the TBSCertificate portion of a certificate is cached in the \fBX509\fR structure internally to improve encoding performance and to ensure certificate signatures are verified correctly in some certificates with broken (non-DER) encodings. .PP If, after modification, the \fBX509\fR object is re-signed with \fBX509_sign()\fR, the encoding is automatically renewed.

The function \fBEVP_PKEY_CTX_get_cb()\fR returns the key or parameter generation callback. .PP The function \fBEVP_PKEY_CTX_get_keygen_info()\fR returns parameters associated with the generation operation. If \fBidx\fR is \-1 the total number of parameters available is returned. Any non negative value returns the value of that parameter. \fBEVP_PKEY_CTX_gen_keygen_info()\fR with a nonnegative value for \&\fBidx\fR should only be called within the generation callback. .PP If the callback returns 0 then the key generation operation is aborted and an error occurs. This might occur during a time consuming operation where a user clicks on a \*(L"cancel\*(R" button. .PP The functions \fBEVP_PKEY_CTX_set_app_data()\fR and \fBEVP_PKEY_CTX_get_app_data()\fR set and retrieve an opaque pointer. This can be used to set some application defined value which can be retrieved in the callback: for example a handle which is used to update a \*(L"progress dialog\*(R". .PP \&\fBEVP_PKEY_check()\fR validates the key-pair given by \fBctx\fR.

Some might not give any useful information at all during key or parameter generation. Others might not even call the callback. .PP The operation performed by key or parameter generation depends on the algorithm used. In some cases (e.g. \s-1EC\s0 with a supplied named curve) the \*(L"generation\*(R" option merely sets the appropriate fields in an \s-1EVP_PKEY\s0 structure. .PP In OpenSSL an \s-1EVP_PKEY\s0 structure containing a private key also contains the public key components and parameters (if any). An OpenSSL private key is equivalent to what some libraries call a \*(L"key pair\*(R".

The sessions can be held in memory for each \fBctx\fR, if more than one \&\s-1SSL_CTX\s0 object is being maintained, the sessions are unique for each \s-1SSL_CTX\s0 object. .PP In order to reuse a session, a client must send the session's id to the server. It can only send exactly one id. The server then either agrees to reuse the session or it starts a full handshake (to create a new session). .PP A server will look up the session in its internal session storage. If the session is not found in internal storage or lookups for the internal storage have been deactivated (\s-1SSL_SESS_CACHE_NO_INTERNAL_LOOKUP\s0), the server will try the external storage if available. .PP Since a client may try to reuse a session intended for use in a different context, the session id context must be set by the server (see \&\fBSSL_CTX_set_session_id_context\fR\|(3)). .PP The following session cache modes and modifiers are available: .IP "\s-1SSL_SESS_CACHE_OFF\s0" 4 .IX Item "SSL_SESS_CACHE_OFF" No session caching for client or server takes place. .IP "\s-1SSL_SESS_CACHE_CLIENT\s0" 4 .IX Item "SSL_SESS_CACHE_CLIENT" Client sessions are added to the session cache. As there is no reliable way for the OpenSSL library to know whether a session should be reused or which session to choose (due to the abstract \s-1BIO\s0 layer the \s-1SSL\s0 engine does not have details about the connection), the application must select the session to be reused by using the \fBSSL_set_session\fR\|(3) function. This option is not activated by default. .IP "\s-1SSL_SESS_CACHE_SERVER\s0" 4 .IX Item "SSL_SESS_CACHE_SERVER" Server sessions are added to the session cache. When a client proposes a session to be reused, the server looks for the corresponding session in (first) the internal session cache (unless \s-1SSL_SESS_CACHE_NO_INTERNAL_LOOKUP\s0 is set), then (second) in the external cache if available. If the session is found, the server will try to reuse the session. This is the default. .IP "\s-1SSL_SESS_CACHE_BOTH\s0" 4 .IX Item "SSL_SESS_CACHE_BOTH" Enable both \s-1SSL_SESS_CACHE_CLIENT\s0 and \s-1SSL_SESS_CACHE_SERVER\s0 at the same time. .IP "\s-1SSL_SESS_CACHE_NO_AUTO_CLEAR\s0" 4 .IX Item "SSL_SESS_CACHE_NO_AUTO_CLEAR" Normally the session cache is checked for expired sessions every 255 connections using the \&\fBSSL_CTX_flush_sessions\fR\|(3) function. Since this may lead to a delay which cannot be controlled, the automatic flushing may be disabled and \&\fBSSL_CTX_flush_sessions\fR\|(3) can be called explicitly by the application. .IP "\s-1SSL_SESS_CACHE_NO_INTERNAL_LOOKUP\s0" 4 .IX Item "SSL_SESS_CACHE_NO_INTERNAL_LOOKUP" By setting this flag, session-resume operations in an \s-1SSL/TLS\s0 server will not automatically look up sessions in the internal cache, even if sessions are automatically stored there. If external session caching callbacks are in use, this flag guarantees that all lookups are directed to the external cache. As automatic lookup only applies for \s-1SSL/TLS\s0 servers, the flag has no effect on clients. .IP "\s-1SSL_SESS_CACHE_NO_INTERNAL_STORE\s0" 4 .IX Item "SSL_SESS_CACHE_NO_INTERNAL_STORE" Depending on the presence of \s-1SSL_SESS_CACHE_CLIENT\s0 and/or \s-1SSL_SESS_CACHE_SERVER,\s0 sessions negotiated in an \s-1SSL/TLS\s0 handshake may be cached for possible reuse. Normally a new session is added to the internal cache as well as any external session caching (callback) that is configured for the \s-1SSL_CTX.\s0 This flag will prevent sessions being stored in the internal cache (though the application can add them manually using \fBSSL_CTX_add_session\fR\|(3)). Note: in any \s-1SSL/TLS\s0 servers where external caching is configured, any successful session lookups in the external cache (i.e. for session-resume requests) would normally be copied into the local cache before processing continues \- this flag prevents these additions to the internal cache as well. .IP "\s-1SSL_SESS_CACHE_NO_INTERNAL\s0" 4 .IX Item "SSL_SESS_CACHE_NO_INTERNAL" Enable both \s-1SSL_SESS_CACHE_NO_INTERNAL_LOOKUP\s0 and \&\s-1SSL_SESS_CACHE_NO_INTERNAL_STORE\s0 at the same time. .PP The default mode is \s-1SSL_SESS_CACHE_SERVER.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set_session_cache_mode()\fR returns the previously set cache mode. .PP \&\fBSSL_CTX_get_session_cache_mode()\fR returns the currently set cache mode. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_set_session\fR\|(3), \&\fBSSL_session_reused\fR\|(3), \&\fBSSL_CTX_add_session\fR\|(3), \&\fBSSL_CTX_sess_number\fR\|(3), \&\fBSSL_CTX_sess_set_cache_size\fR\|(3), \&\fBSSL_CTX_sess_set_get_cb\fR\|(3), \&\fBSSL_CTX_set_session_id_context\fR\|(3), \&\fBSSL_CTX_set_timeout\fR\|(3), \&\fBSSL_CTX_flush_sessions\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2020 The OpenSSL Project Authors.

When constructing a curve using EC_GROUP_new (see \fBEC_GROUP_new\fR\|(3)) an implementation method must be provided. The functions described here all return a const pointer to an \&\fB\s-1EC_METHOD\s0\fR structure that can be passed to \s-1EC_GROUP_NEW.\s0 It is important that the correct implementation type for the form of curve selected is used. .PP For F2^m curves there is only one implementation choice, i.e. EC_GF2_simple_method. .PP For Fp curves the lowest common denominator implementation is the EC_GFp_simple_method implementation. All other implementations are based on this one. EC_GFp_mont_method builds on EC_GFp_simple_method but adds the use of montgomery multiplication (see \fBBN_mod_mul_montgomery\fR\|(3)). EC_GFp_nist_method offers an implementation optimised for use with \s-1NIST\s0 recommended curves (\s-1NIST\s0 curves are available through EC_GROUP_new_by_curve_name as described in \fBEC_GROUP_new\fR\|(3)). .PP The functions EC_GFp_nistp224_method, EC_GFp_nistp256_method and EC_GFp_nistp521_method offer 64 bit optimised implementations for the \s-1NIST P224, P256\s0 and P521 curves respectively. Note, however, that these implementations are not available on all platforms. .PP EC_METHOD_get_field_type identifies what type of field the \s-1EC_METHOD\s0 structure supports, which will be either F2^m or Fp. If the field type is Fp then the value \fBNID_X9_62_prime_field\fR is returned. If the field type is F2^m then the value \fBNID_X9_62_characteristic_two_field\fR is returned. These values are defined in the obj_mac.h header file. .SH "RETURN VALUES" .IX Header "RETURN VALUES" All EC_GFp* functions and EC_GF2m_simple_method always return a const pointer to an \s-1EC_METHOD\s0 structure. .PP EC_METHOD_get_field_type returns an integer that identifies the type of field the \s-1EC_METHOD\s0 structure supports. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBcrypto\fR\|(7), \fBEC_GROUP_new\fR\|(3), \fBEC_GROUP_copy\fR\|(3), \&\fBEC_POINT_new\fR\|(3), \fBEC_POINT_add\fR\|(3), \fBEC_KEY_new\fR\|(3), \&\fBd2i_ECPKParameters\fR\|(3), \&\fBBN_mod_mul_montgomery\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2013\-2017 The OpenSSL Project Authors.

The signer's certificate must still be supplied in the \fIsigncert\fR parameter though. This can reduce the size of the signatures if the signer's certificates can be obtained by other means: for example a previously signed message. .PP The data being signed is included in the \s-1PKCS7\s0 structure, unless \&\fB\s-1PKCS7_DETACHED\s0\fR is set in which case it is omitted. This is used for \s-1PKCS7\s0 detached signatures which are used in S/MIME plaintext signed messages for example. .PP Normally the supplied content is translated into \s-1MIME\s0 canonical format (as required by the S/MIME specifications) if \fB\s-1PKCS7_BINARY\s0\fR is set no translation occurs. This option should be used if the supplied data is in binary format otherwise the translation will corrupt it. .PP The signedData structure includes several PKCS#7 authenticatedAttributes including the signing time, the PKCS#7 content type and the supported list of ciphers in an SMIMECapabilities attribute. If \fB\s-1PKCS7_NOATTR\s0\fR is set then no authenticatedAttributes will be used. If \fB\s-1PKCS7_NOSMIMECAP\s0\fR is set then just the SMIMECapabilities are omitted. .PP If present the SMIMECapabilities attribute indicates support for the following algorithms: triple \s-1DES, 128\s0 bit \s-1RC2, 64\s0 bit \s-1RC2, DES\s0 and 40 bit \s-1RC2.\s0 If any of these algorithms is disabled then it will not be included. .PP If the flags \fB\s-1PKCS7_STREAM\s0\fR is set then the returned \fB\s-1PKCS7\s0\fR structure is just initialized ready to perform the signing operation.

The first form is those defined over the prime field Fp. The elements of Fp are the integers 0 to p\-1, where p is a prime number. This gives us a revised elliptic curve equation as follows: .PP y^2 mod p = x^3 +ax + b mod p .PP The second form is those defined over a binary field F2^m where the elements of the field are integers of length at most m bits. For this form the elliptic curve equation is modified to: .PP y^2 + xy = x^3 + ax^2 + b (where b != 0) .PP Operations in a binary field are performed relative to an \fBirreducible polynomial\fR. All such curves with OpenSSL use a trinomial or a pentanomial for this parameter. .PP A new curve can be constructed by calling \fBEC_GROUP_new()\fR, using the implementation provided by \fBmeth\fR (see \fBEC_GFp_simple_method\fR\|(3)). It is then necessary to call \fBEC_GROUP_set_curve()\fR to set the curve parameters. \&\fBEC_GROUP_new_from_ecparameters()\fR will create a group from the specified \&\fBparams\fR and \fBEC_GROUP_new_from_ecpkparameters()\fR will create a group from the specific \s-1PK\s0 \fBparams\fR. .PP \&\fBEC_GROUP_set_curve()\fR sets the curve parameters \fBp\fR, \fBa\fR and \fBb\fR. For a curve over Fp \fBp\fR is the prime for the field. For a curve over F2^m \fBp\fR represents the irreducible polynomial \- each bit represents a term in the polynomial. Therefore, there will either be three or five bits set dependent on whether the polynomial is a trinomial or a pentanomial. In either case, \fBa\fR and \fBb\fR represents the coefficients a and b from the relevant equation introduced above. .PP \&\fBEC_group_get_curve()\fR obtains the previously set curve parameters. .PP \&\fBEC_GROUP_set_curve_GFp()\fR and \fBEC_GROUP_set_curve_GF2m()\fR are synonyms for \&\fBEC_GROUP_set_curve()\fR. They are defined for backwards compatibility only and should not be used. .PP \&\fBEC_GROUP_get_curve_GFp()\fR and \fBEC_GROUP_get_curve_GF2m()\fR are synonyms for \&\fBEC_GROUP_get_curve()\fR. They are defined for backwards compatibility only and should not be used. .PP The functions \fBEC_GROUP_new_curve_GFp()\fR and \fBEC_GROUP_new_curve_GF2m()\fR are shortcuts for calling \fBEC_GROUP_new()\fR and then the \fBEC_GROUP_set_curve()\fR function. An appropriate default implementation method will be used. .PP Whilst the library can be used to create any curve using the functions described above, there are also a number of predefined curves that are available. In order to obtain a list of all of the predefined curves, call the function \&\fBEC_get_builtin_curves()\fR. The parameter \fBr\fR should be an array of EC_builtin_curve structures of size \fBnitems\fR. The function will populate the \&\fBr\fR array with information about the builtin curves. If \fBnitems\fR is less than the total number of curves available, then the first \fBnitems\fR curves will be returned. Otherwise the total number of curves will be provided. The return value is the total number of curves available (whether that number has been populated in \fBr\fR or not). Passing a \s-1NULL\s0 \fBr\fR, or setting \fBnitems\fR to 0 will do nothing other than return the total number of curves available. The EC_builtin_curve structure is defined as follows: .PP .Vb 4 \& typedef struct { \& int nid; \& const char *comment; \& } EC_builtin_curve; .Ve .PP Each EC_builtin_curve item has a unique integer id (\fBnid\fR), and a human readable comment string describing the curve. .PP In order to construct a builtin curve use the function \&\fBEC_GROUP_new_by_curve_name()\fR and provide the \fBnid\fR of the curve to be constructed. .PP \&\fBEC_GROUP_free()\fR frees the memory associated with the \s-1EC_GROUP.\s0 If \fBgroup\fR is \s-1NULL\s0 nothing is done. .PP \&\fBEC_GROUP_clear_free()\fR destroys any sensitive data held within the \s-1EC_GROUP\s0 and then frees its memory. If \fBgroup\fR is \s-1NULL\s0 nothing is done. .SH "RETURN VALUES" .IX Header "RETURN VALUES" All EC_GROUP_new* functions return a pointer to the newly constructed group, or \&\s-1NULL\s0 on error. .PP \&\fBEC_get_builtin_curves()\fR returns the number of builtin curves that are available. .PP \&\fBEC_GROUP_set_curve_GFp()\fR, \fBEC_GROUP_get_curve_GFp()\fR, \fBEC_GROUP_set_curve_GF2m()\fR, \&\fBEC_GROUP_get_curve_GF2m()\fR return 1 on success or 0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBcrypto\fR\|(7), \fBEC_GROUP_copy\fR\|(3), \&\fBEC_POINT_new\fR\|(3), \fBEC_POINT_add\fR\|(3), \fBEC_KEY_new\fR\|(3), \&\fBEC_GFp_simple_method\fR\|(3), \fBd2i_ECPKParameters\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2013\-2020 The OpenSSL Project Authors.

If \fBname\fR is \s-1NULL,\s0 or the empty string the list of hostnames is cleared, and name checks are not performed on the peer certificate. When a nonempty \&\fBname\fR is specified, certificate verification automatically checks the peer hostname via \fBX509_check_host\fR\|(3) with \fBflags\fR as specified via \fBSSL_set_hostflags()\fR. Clients that enable \s-1DANE TLSA\s0 authentication via \fBSSL_dane_enable\fR\|(3) should leave it to that function to set the primary reference identifier of the peer, and should not call \&\fBSSL_set1_host()\fR. .PP \&\fBSSL_add1_host()\fR adds \fBname\fR as an additional reference identifier that can match the peer's certificate.

See \fBX509_check_host\fR\|(3) for the list of available flags and their meaning. .PP \&\fBSSL_get0_peername()\fR returns the \s-1DNS\s0 hostname or subject CommonName from the peer certificate that matched one of the reference identifiers. When wildcard matching is not disabled, the name matched in the peer certificate may be a wildcard name. When one of the reference identifiers configured via \fBSSL_set1_host()\fR or \&\fBSSL_add1_host()\fR starts with \*(L".\*(R", which indicates a parent domain prefix rather than a fixed name, the matched peer name may be a sub-domain of the reference identifier. The returned string is allocated by the library and is no longer valid once the associated \fBssl\fR handle is cleared or freed, or a renegotiation takes place. Applications must not free the return value. .PP \&\s-1SSL\s0 clients are advised to use these functions in preference to explicitly calling \fBX509_check_host\fR\|(3). Hostname checks may be out of scope with the \s-1RFC7671 \fBDANE\-EE\s0\fR\|(3) certificate usage, and the internal check will be suppressed as appropriate when \s-1DANE\s0 is enabled. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_set1_host()\fR and \fBSSL_add1_host()\fR return 1 for success and 0 for failure. .PP \&\fBSSL_get0_peername()\fR returns \s-1NULL\s0 if peername verification is not applicable (as with \s-1RFC7671 \fBDANE\-EE\s0\fR\|(3)), or no trusted peername was matched.

A new point is constructed by calling the function \fBEC_POINT_new()\fR and providing the \&\fBgroup\fR object that the point relates to. .PP \&\fBEC_POINT_free()\fR frees the memory associated with the \fB\s-1EC_POINT\s0\fR. if \fBpoint\fR is \s-1NULL\s0 nothing is done. .PP \&\fBEC_POINT_clear_free()\fR destroys any sensitive data held within the \s-1EC_POINT\s0 and then frees its memory. If \fBpoint\fR is \s-1NULL\s0 nothing is done. .PP \&\fBEC_POINT_copy()\fR copies the point \fBsrc\fR into \fBdst\fR. Both \fBsrc\fR and \fBdst\fR must use the same \fB\s-1EC_METHOD\s0\fR. .PP \&\fBEC_POINT_dup()\fR creates a new \fB\s-1EC_POINT\s0\fR object and copies the content from \&\fBsrc\fR to the newly created \fB\s-1EC_POINT\s0\fR object. .PP \&\fBEC_POINT_method_of()\fR obtains the \fB\s-1EC_METHOD\s0\fR associated with \fBpoint\fR. .PP A valid point on a curve is the special point at infinity. A point is set to be at infinity by calling \fBEC_POINT_set_to_infinity()\fR. .PP The affine co-ordinates for a point describe a point in terms of its x and y position. The function \fBEC_POINT_set_affine_coordinates()\fR sets the \fBx\fR and \fBy\fR co-ordinates for the point \fBp\fR defined over the curve given in \fBgroup\fR. The function \fBEC_POINT_get_affine_coordinates()\fR sets \fBx\fR and \fBy\fR, either of which may be \s-1NULL,\s0 to the corresponding coordinates of \fBp\fR. .PP The functions \fBEC_POINT_set_affine_coordinates_GFp()\fR and \&\fBEC_POINT_set_affine_coordinates_GF2m()\fR are synonyms for \&\fBEC_POINT_set_affine_coordinates()\fR. They are defined for backwards compatibility only and should not be used. .PP The functions \fBEC_POINT_get_affine_coordinates_GFp()\fR and \&\fBEC_POINT_get_affine_coordinates_GF2m()\fR are synonyms for \&\fBEC_POINT_get_affine_coordinates()\fR. They are defined for backwards compatibility only and should not be used. .PP As well as the affine co-ordinates, a point can alternatively be described in terms of its Jacobian projective co-ordinates (for Fp curves only). Jacobian projective co-ordinates are expressed as three values x, y and z. Working in this co-ordinate system provides more efficient point multiplication operations. A mapping exists between Jacobian projective co-ordinates and affine co-ordinates. A Jacobian projective co-ordinate (x, y, z) can be written as an affine co-ordinate as (x/(z^2), y/(z^3)). Conversion to Jacobian projective from affine co-ordinates is simple. The co-ordinate (x, y) is mapped to (x, y, 1). To set or get the projective co-ordinates use \&\fBEC_POINT_set_Jprojective_coordinates_GFp()\fR and \&\fBEC_POINT_get_Jprojective_coordinates_GFp()\fR respectively. .PP Points can also be described in terms of their compressed co-ordinates. For a point (x, y), for any given value for x such that the point is on the curve there will only ever be two possible values for y. Therefore, a point can be set using the \fBEC_POINT_set_compressed_coordinates()\fR function where \fBx\fR is the x co-ordinate and \fBy_bit\fR is a value 0 or 1 to identify which of the two possible values for y should be used. .PP The functions \fBEC_POINT_set_compressed_coordinates_GFp()\fR and \&\fBEC_POINT_set_compressed_coordinates_GF2m()\fR are synonyms for \&\fBEC_POINT_set_compressed_coordinates()\fR. They are defined for backwards compatibility only and should not be used. .PP In addition \fB\s-1EC_POINT\s0\fR can be converted to and from various external representations. The octet form is the binary encoding of the \fBECPoint\fR structure (as defined in \s-1RFC5480\s0 and used in certificates and \s-1TLS\s0 records): only the content octets are present, the \fB\s-1OCTET STRING\s0\fR tag and length are not included. \fB\s-1BIGNUM\s0\fR form is the octet form interpreted as a big endian integer converted to a \fB\s-1BIGNUM\s0\fR structure. Hexadecimal form is the octet form converted to a \s-1NULL\s0 terminated character string where each character is one of the printable values 0\-9 or A\-F (or a\-f). .PP The functions \fBEC_POINT_point2oct()\fR, \fBEC_POINT_oct2point()\fR, \fBEC_POINT_point2bn()\fR, \&\fBEC_POINT_bn2point()\fR, \fBEC_POINT_point2hex()\fR and \fBEC_POINT_hex2point()\fR convert from and to EC_POINTs for the formats: octet, \s-1BIGNUM\s0 and hexadecimal respectively. .PP The function \fBEC_POINT_point2oct()\fR encodes the given curve point \fBp\fR as an octet string into the buffer \fBbuf\fR of size \fBlen\fR, using the specified conversion form \fBform\fR. The encoding conforms with Sec. 2.3.3 of the \s-1SECG SEC 1\s0 (\*(L"Elliptic Curve Cryptography\*(R") standard. Similarly the function \fBEC_POINT_oct2point()\fR decodes a curve point into \fBp\fR from the octet string contained in the given buffer \fBbuf\fR of size \fBlen\fR, conforming to Sec. 2.3.4 of the \s-1SECG SEC 1\s0 (\*(L"Elliptic Curve Cryptography\*(R") standard. .PP The functions \fBEC_POINT_point2hex()\fR and \fBEC_POINT_point2bn()\fR convert a point \fBp\fR, respectively, to the hexadecimal or \s-1BIGNUM\s0 representation of the same encoding of the function \fBEC_POINT_point2oct()\fR. Vice versa, similarly to the function \fBEC_POINT_oct2point()\fR, the functions \&\fBEC_POINT_hex2point()\fR and \fBEC_POINT_point2bn()\fR decode the hexadecimal or \&\s-1BIGNUM\s0 representation into the \s-1EC_POINT\s0 \fBp\fR. .PP Notice that, according to the standard, the octet string encoding of the point at infinity for a given curve is fixed to a single octet of value zero and that, vice versa, a single octet of size zero is decoded as the point at infinity. .PP The function \fBEC_POINT_point2oct()\fR must be supplied with a buffer long enough to store the octet form. The return value provides the number of octets stored. Calling the function with a \s-1NULL\s0 buffer will not perform the conversion but will still return the required buffer length. .PP The function \fBEC_POINT_point2buf()\fR allocates a buffer of suitable length and writes an \s-1EC_POINT\s0 to it in octet format. The allocated buffer is written to \&\fB*pbuf\fR and its length is returned. The caller must free up the allocated buffer with a call to \fBOPENSSL_free()\fR. Since the allocated buffer value is written to \fB*pbuf\fR the \fBpbuf\fR parameter \fB\s-1MUST NOT\s0\fR be \fB\s-1NULL\s0\fR. .PP The function \fBEC_POINT_point2hex()\fR will allocate sufficient memory to store the hexadecimal string. It is the caller's responsibility to free this memory with a subsequent call to \fBOPENSSL_free()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEC_POINT_new()\fR and \fBEC_POINT_dup()\fR return the newly allocated \s-1EC_POINT\s0 or \s-1NULL\s0 on error. .PP The following functions return 1 on success or 0 on error: \fBEC_POINT_copy()\fR, \&\fBEC_POINT_set_to_infinity()\fR, \fBEC_POINT_set_Jprojective_coordinates_GFp()\fR, \&\fBEC_POINT_get_Jprojective_coordinates_GFp()\fR, \&\fBEC_POINT_set_affine_coordinates_GFp()\fR, \fBEC_POINT_get_affine_coordinates_GFp()\fR, \&\fBEC_POINT_set_compressed_coordinates_GFp()\fR, \&\fBEC_POINT_set_affine_coordinates_GF2m()\fR, \fBEC_POINT_get_affine_coordinates_GF2m()\fR, \&\fBEC_POINT_set_compressed_coordinates_GF2m()\fR and \fBEC_POINT_oct2point()\fR. .PP EC_POINT_method_of returns the \s-1EC_METHOD\s0 associated with the supplied \s-1EC_POINT.\s0 .PP \&\fBEC_POINT_point2oct()\fR and \fBEC_POINT_point2buf()\fR return the length of the required buffer or 0 on error. .PP \&\fBEC_POINT_point2bn()\fR returns the pointer to the \s-1BIGNUM\s0 supplied, or \s-1NULL\s0 on error. .PP \&\fBEC_POINT_bn2point()\fR returns the pointer to the \s-1EC_POINT\s0 supplied, or \s-1NULL\s0 on error. .PP \&\fBEC_POINT_point2hex()\fR returns a pointer to the hex string, or \s-1NULL\s0 on error. .PP \&\fBEC_POINT_hex2point()\fR returns the pointer to the \s-1EC_POINT\s0 supplied, or \s-1NULL\s0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBcrypto\fR\|(7), \fBEC_GROUP_new\fR\|(3), \fBEC_GROUP_copy\fR\|(3), \&\fBEC_POINT_add\fR\|(3), \fBEC_KEY_new\fR\|(3), \&\fBEC_GFp_simple_method\fR\|(3), \fBd2i_ECPKParameters\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2013\-2020 The OpenSSL Project Authors.

This works in a similar way for \&\fBSSL_write()\fR. When not set (the default), \fBSSL_write_ex()\fR or \fBSSL_write()\fR will only report success once the complete chunk was written. Once \fBSSL_write_ex()\fR or \&\fBSSL_write()\fR returns successful, \fBr\fR bytes have been written and the next call to \fBSSL_write_ex()\fR or \fBSSL_write()\fR must only send the n\-r bytes left, imitating the behaviour of \fBwrite()\fR. .IP "\s-1SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER\s0" 4 .IX Item "SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER" Make it possible to retry \fBSSL_write_ex()\fR or \fBSSL_write()\fR with changed buffer location (the buffer contents must stay the same). This is not the default to avoid the misconception that nonblocking \fBSSL_write()\fR behaves like nonblocking \fBwrite()\fR. .IP "\s-1SSL_MODE_AUTO_RETRY\s0" 4 .IX Item "SSL_MODE_AUTO_RETRY" During normal operations, non-application data records might need to be sent or received that the application is not aware of. If a non-application data record was processed, \&\fBSSL_read_ex\fR\|(3) and \fBSSL_read\fR\|(3) can return with a failure and indicate the need to retry with \fB\s-1SSL_ERROR_WANT_READ\s0\fR. If such a non-application data record was processed, the flag \&\fB\s-1SSL_MODE_AUTO_RETRY\s0\fR causes it to try to process the next record instead of returning. .Sp In a nonblocking environment applications must be prepared to handle incomplete read/write operations. Setting \fB\s-1SSL_MODE_AUTO_RETRY\s0\fR for a nonblocking \fB\s-1BIO\s0\fR will process non-application data records until either no more data is available or an application data record has been processed. .Sp In a blocking environment, applications are not always prepared to deal with the functions returning intermediate reports such as retry requests, and setting the \fB\s-1SSL_MODE_AUTO_RETRY\s0\fR flag will cause the functions to only return after successfully processing an application data record or a failure. .Sp Turning off \fB\s-1SSL_MODE_AUTO_RETRY\s0\fR can be useful with blocking \fB\s-1BIO\s0\fRs in case they are used in combination with something like \fBselect()\fR or \fBpoll()\fR. Otherwise the call to \fBSSL_read()\fR or \fBSSL_read_ex()\fR might hang when a non-application record was sent and no application data was sent. .IP "\s-1SSL_MODE_RELEASE_BUFFERS\s0" 4 .IX Item "SSL_MODE_RELEASE_BUFFERS" When we no longer need a read buffer or a write buffer for a given \s-1SSL,\s0 then release the memory we were using to hold it.

The callback function should identify an \s-1SSL_SESSION\s0 object that provides the \s-1PSK\s0 details and store it in \fB*sess\fR. The \s-1SSL_SESSION\s0 object should, as a minimum, set the master key, the ciphersuite and the protocol version. See \&\fBSSL_CTX_set_psk_use_session_callback\fR\|(3) for details. .PP It is also possible for the callback to succeed but not supply a \s-1PSK.\s0 In this case no \s-1PSK\s0 will be used but the handshake will continue. To do this the callback should return successfully and ensure that \fB*sess\fR is \&\s-1NULL.\s0 .PP Identity hints are not relevant for TLSv1.3. A server application wishing to use \&\s-1PSK\s0 ciphersuites for TLSv1.2 and below may call \fBSSL_CTX_use_psk_identity_hint()\fR to set the given \fB\s-1NUL\s0\fR\-terminated \s-1PSK\s0 identity hint \fBhint\fR for \s-1SSL\s0 context object \fBctx\fR. \fBSSL_use_psk_identity_hint()\fR sets the given \fB\s-1NUL\s0\fR\-terminated \s-1PSK\s0 identity hint \fBhint\fR for the \s-1SSL\s0 connection object \fBssl\fR. If \fBhint\fR is \&\fB\s-1NULL\s0\fR the current hint from \fBctx\fR or \fBssl\fR is deleted. .PP In the case where \s-1PSK\s0 identity hint is \fB\s-1NULL\s0\fR, the server does not send the ServerKeyExchange message to the client. .PP A server application wishing to use PSKs for TLSv1.2 and below must provide a callback function which is called when the server receives the ClientKeyExchange message from the client. The purpose of the callback function is to validate the received \s-1PSK\s0 identity and to fetch the pre-shared key used during the connection setup phase. The callback is set using the functions \&\fBSSL_CTX_set_psk_server_callback()\fR or \fBSSL_set_psk_server_callback()\fR. The callback function is given the connection in parameter \fBssl\fR, \fB\s-1NUL\s0\fR\-terminated \s-1PSK\s0 identity sent by the client in parameter \fBidentity\fR, and a buffer \fBpsk\fR of length \fBmax_psk_len\fR bytes where the pre-shared key is to be stored. .PP The callback for use in TLSv1.2 will also work in TLSv1.3 although it is recommended to use \fBSSL_CTX_set_psk_find_session_callback()\fR or \fBSSL_set_psk_find_session_callback()\fR for this purpose instead. If TLSv1.3 has been negotiated then OpenSSL will first check to see if a callback has been set via \fBSSL_CTX_set_psk_find_session_callback()\fR or \fBSSL_set_psk_find_session_callback()\fR and it will use that in preference. If no such callback is present then it will check to see if a callback has been set via \fBSSL_CTX_set_psk_server_callback()\fR or \&\fBSSL_set_psk_server_callback()\fR and use that. In this case the handshake digest will default to \s-1SHA\-256\s0 for any returned \s-1PSK.\s0 TLSv1.3 early data exchanges are possible in \s-1PSK\s0 connections only with the \fBSSL_psk_find_session_cb_func\fR callback, and are not possible with the \fBSSL_psk_server_cb_func\fR callback. .SH "NOTES" .IX Header "NOTES" A connection established via a TLSv1.3 \s-1PSK\s0 will appear as if session resumption has occurred so that \fBSSL_session_reused\fR\|(3) will return true. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fB\fBSSL_CTX_use_psk_identity_hint()\fB\fR and \fB\fBSSL_use_psk_identity_hint()\fB\fR return 1 on success, 0 otherwise. .PP Return values from the TLSv1.2 and below server callback are interpreted as follows: .IP "0" 4 \&\s-1PSK\s0 identity was not found. An \*(L"unknown_psk_identity\*(R" alert message will be sent and the connection setup fails. .IP ">0" 4 .IX Item ">0" \&\s-1PSK\s0 identity was found and the server callback has provided the \s-1PSK\s0 successfully in parameter \fBpsk\fR. Return value is the length of \&\fBpsk\fR in bytes. It is an error to return a value greater than \&\fBmax_psk_len\fR. .Sp If the \s-1PSK\s0 identity was not found but the callback instructs the protocol to continue anyway, the callback must provide some random data to \fBpsk\fR and return the length of the random data, so the connection will fail with decryption_error before it will be finished completely. .PP The \fBSSL_psk_find_session_cb_func\fR callback should return 1 on success or 0 on failure. In the event of failure the connection setup fails. .SH "NOTES" .IX Header "NOTES" There are no known security issues with sharing the same \s-1PSK\s0 between TLSv1.2 (or below) and TLSv1.3. However, the \s-1RFC\s0 has this note of caution: .PP \&\*(L"While there is no known way in which the same \s-1PSK\s0 might produce related output in both versions, only limited analysis has been done. Implementations can ensure safety from cross-protocol related output by not reusing PSKs between \&\s-1TLS 1.3\s0 and \s-1TLS 1.2.\*(R"\s0 .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CTX_set_psk_use_session_callback\fR\|(3), \&\fBSSL_set_psk_use_session_callback\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fBSSL_CTX_set_psk_find_session_callback()\fR and \fBSSL_set_psk_find_session_callback()\fR were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2006\-2020 The OpenSSL Project Authors.

By modifying the method, alternative implementations such as hardware accelerators may be used. \s-1IMPORTANT:\s0 See the \s-1NOTES\s0 section for important information about how these \s-1RSA API\s0 functions are affected by the use of \fB\s-1ENGINE\s0\fR \s-1API\s0 calls. .PP Initially, the default \s-1RSA_METHOD\s0 is the OpenSSL internal implementation, as returned by \fBRSA_PKCS1_OpenSSL()\fR. .PP \&\fBRSA_set_default_method()\fR makes \fBmeth\fR the default method for all \s-1RSA\s0 structures created later. \&\fB\s-1NB\s0\fR: This is true only whilst no \s-1ENGINE\s0 has been set as a default for \s-1RSA,\s0 so this function is no longer recommended. This function is not thread-safe and should not be called at the same time as other OpenSSL functions. .PP \&\fBRSA_get_default_method()\fR returns a pointer to the current default \&\s-1RSA_METHOD.\s0 However, the meaningfulness of this result is dependent on whether the \s-1ENGINE API\s0 is being used, so this function is no longer recommended. .PP \&\fBRSA_set_method()\fR selects \fBmeth\fR to perform all operations using the key \&\fBrsa\fR. This will replace the \s-1RSA_METHOD\s0 used by the \s-1RSA\s0 key and if the previous method was supplied by an \s-1ENGINE,\s0 the handle to that \s-1ENGINE\s0 will be released during the change. It is possible to have \s-1RSA\s0 keys that only work with certain \s-1RSA_METHOD\s0 implementations (e.g. from an \s-1ENGINE\s0 module that supports embedded hardware-protected keys), and in such cases attempting to change the \s-1RSA_METHOD\s0 for the key can have unexpected results. .PP \&\fBRSA_get_method()\fR returns a pointer to the \s-1RSA_METHOD\s0 being used by \fBrsa\fR. This method may or may not be supplied by an \s-1ENGINE\s0 implementation, but if it is, the return value can only be guaranteed to be valid as long as the \&\s-1RSA\s0 key itself is valid and does not have its implementation changed by \&\fBRSA_set_method()\fR. .PP \&\fBRSA_flags()\fR returns the \fBflags\fR that are set for \fBrsa\fR's current \&\s-1RSA_METHOD.\s0 See the \s-1BUGS\s0 section. .PP \&\fBRSA_new_method()\fR allocates and initializes an \s-1RSA\s0 structure so that \&\fBengine\fR will be used for the \s-1RSA\s0 operations. If \fBengine\fR is \s-1NULL,\s0 the default \s-1ENGINE\s0 for \s-1RSA\s0 operations is used, and if no default \s-1ENGINE\s0 is set, the \s-1RSA_METHOD\s0 controlled by \fBRSA_set_default_method()\fR is used. .PP \&\fBRSA_flags()\fR returns the \fBflags\fR that are set for \fBrsa\fR's current method. .PP \&\fBRSA_new_method()\fR allocates and initializes an \fB\s-1RSA\s0\fR structure so that \&\fBmethod\fR will be used for the \s-1RSA\s0 operations.

However, this return value should probably be ignored because if it was supplied by an \s-1ENGINE,\s0 the pointer could be invalidated at any time if the \s-1ENGINE\s0 is unloaded (in fact it could be unloaded as a result of the \fBRSA_set_method()\fR function releasing its handle to the \&\s-1ENGINE\s0). For this reason, the return type may be replaced with a \fBvoid\fR declaration in a future release. .PP \&\fBRSA_new_method()\fR returns \s-1NULL\s0 and sets an error code that can be obtained by \fBERR_get_error\fR\|(3) if the allocation fails. Otherwise it returns a pointer to the newly allocated structure. .SH "BUGS" .IX Header "BUGS" The behaviour of \fBRSA_flags()\fR is a mis-feature that is left as-is for now to avoid creating compatibility problems. \s-1RSA\s0 functionality, such as the encryption functions, are controlled by the \fBflags\fR value in the \s-1RSA\s0 key itself, not by the \fBflags\fR value in the \s-1RSA_METHOD\s0 attached to the \s-1RSA\s0 key (which is what this function returns).

A whole record is processed (e.g. decrypted) in one go and is buffered by OpenSSL until it is read by the application via a call to \fBSSL_read_ex\fR\|(3) or \fBSSL_read\fR\|(3). .PP \&\fBSSL_pending()\fR returns the number of bytes which have been processed, buffered and are available inside \fBssl\fR for immediate read. .PP If the \fB\s-1SSL\s0\fR object's \fIread_ahead\fR flag is set (see \&\fBSSL_CTX_set_read_ahead\fR\|(3)), additional protocol bytes (beyond the current record) may have been read containing more \s-1TLS/SSL\s0 records. This also applies to \&\s-1DTLS\s0 and pipelining (see \fBSSL_CTX_set_split_send_fragment\fR\|(3)). These additional bytes will be buffered by OpenSSL but will remain unprocessed until they are needed. As these bytes are still in an unprocessed state \fBSSL_pending()\fR will ignore them. Therefore, it is possible for no more bytes to be readable from the underlying \s-1BIO\s0 (because OpenSSL has already read them) and for \fBSSL_pending()\fR to return 0, even though readable application data bytes are available (because the data is in unprocessed buffered records). .PP \&\fBSSL_has_pending()\fR returns 1 if \fBs\fR has buffered data (whether processed or unprocessed) and 0 otherwise. Note that it is possible for \fBSSL_has_pending()\fR to return 1, and then a subsequent call to \fBSSL_read_ex()\fR or \fBSSL_read()\fR to return no data because the unprocessed buffered data when processed yielded no application data (for example this can happen during renegotiation). It is also possible in this scenario for \fBSSL_has_pending()\fR to continue to return 1 even after an \&\fBSSL_read_ex()\fR or \fBSSL_read()\fR call because the buffered and unprocessed data is not yet processable (e.g. because OpenSSL has only received a partial record so far). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_pending()\fR returns the number of buffered and processed application data bytes that are pending and are available for immediate read. \fBSSL_has_pending()\fR returns 1 if there is buffered record data in the \s-1SSL\s0 object and 0 otherwise. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_read_ex\fR\|(3), \fBSSL_read\fR\|(3), \fBSSL_CTX_set_read_ahead\fR\|(3), \&\fBSSL_CTX_set_split_send_fragment\fR\|(3), \fBssl\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" The \fBSSL_has_pending()\fR function was added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

For example, by default, the host \fBname\fR \*(L"www.example.com\*(R" would match a certificate with a \s-1SAN\s0 or \s-1CN\s0 value of \*(L"*.example.com\*(R", \*(L"w*.example.com\*(R" or \*(L"*w.example.com\*(R". .PP Per section 6.4.2 of \s-1RFC 6125,\s0 \fBname\fR values representing international domain names must be given in A\-label form. The \fBnamelen\fR argument must be the number of characters in the name string or zero in which case the length is calculated with strlen(\fBname\fR). When \fBname\fR starts with a dot (e.g. \*(L".example.com\*(R"), it will be matched by a certificate valid for any sub-domain of \fBname\fR, (see also \&\fBX509_CHECK_FLAG_SINGLE_LABEL_SUBDOMAINS\fR below). .PP When the certificate is matched, and \fBpeername\fR is not \s-1NULL,\s0 a pointer to a copy of the matching \s-1SAN\s0 or \s-1CN\s0 from the peer certificate is stored at the address passed in \fBpeername\fR. The application is responsible for freeing the peername via \fBOPENSSL_free()\fR when it is no longer needed. .PP \&\fBX509_check_email()\fR checks if the certificate matches the specified email \fBaddress\fR. Only the mailbox syntax of \s-1RFC 822\s0 is supported, comments are not allowed, and no attempt is made to normalize quoted characters. The \fBaddresslen\fR argument must be the number of characters in the address string or zero in which case the length is calculated with strlen(\fBaddress\fR). .PP \&\fBX509_check_ip()\fR checks if the certificate matches a specified IPv4 or IPv6 address. The \fBaddress\fR array is in binary format, in network byte order. The length is either 4 (IPv4) or 16 (IPv6). Only explicitly marked addresses in the certificates are considered; \s-1IP\s0 addresses stored in \s-1DNS\s0 names and Common Names are ignored. .PP \&\fBX509_check_ip_asc()\fR is similar, except that the NUL-terminated string \fBaddress\fR is first converted to the internal representation. .PP The \fBflags\fR argument is usually 0.

If both \fBX509_CHECK_FLAG_ALWAYS_CHECK_SUBJECT\fR and \&\fBX509_CHECK_FLAG_NEVER_CHECK_SUBJECT\fR are specified, the latter takes precedence and the subject \s-1DN\s0 is not checked for matching names. .PP If set, \fBX509_CHECK_FLAG_NO_WILDCARDS\fR disables wildcard expansion; this only applies to \fBX509_check_host\fR. .PP If set, \fBX509_CHECK_FLAG_NO_PARTIAL_WILDCARDS\fR suppresses support for \*(L"*\*(R" as wildcard pattern in labels that have a prefix or suffix, such as: \*(L"www*\*(R" or \*(L"*www\*(R"; this only applies to \fBX509_check_host\fR. .PP If set, \fBX509_CHECK_FLAG_MULTI_LABEL_WILDCARDS\fR allows a \*(L"*\*(R" that constitutes the complete label of a \s-1DNS\s0 name (e.g. \*(L"*.example.com\*(R") to match more than one label in \fBname\fR; this flag only applies to \fBX509_check_host\fR. .PP If set, \fBX509_CHECK_FLAG_SINGLE_LABEL_SUBDOMAINS\fR restricts \fBname\fR values which start with \*(L".\*(R", that would otherwise match any sub-domain in the peer certificate, to only match direct child sub-domains. Thus, for instance, with this flag set a \fBname\fR of \*(L".example.com\*(R" would match a peer certificate with a \s-1DNS\s0 name of \*(L"www.example.com\*(R", but would not match a peer certificate with a \s-1DNS\s0 name of \&\*(L"www.sub.example.com\*(R"; this flag only applies to \fBX509_check_host\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The functions return 1 for a successful match, 0 for a failed match and \-1 for an internal error: typically a memory allocation failure or an \s-1ASN.1\s0 decoding error. .PP All functions can also return \-2 if the input is malformed.

The hash table entries can be arbitrary structures. Usually they consist of key and value fields. In the description here, \fI\s-1TYPE\s0\fR is used a placeholder for any of the OpenSSL datatypes, such as \fI\s-1SSL_SESSION\s0\fR. .PP \&\fBlh_TYPE_new()\fR creates a new \fB\s-1LHASH_OF\s0(\s-1TYPE\s0)\fR structure to store arbitrary data entries, and specifies the 'hash' and 'compare' callbacks to be used in organising the table's entries. The \fBhash\fR callback takes a pointer to a table entry as its argument and returns an unsigned long hash value for its key field. The hash value is normally truncated to a power of 2, so make sure that your hash function returns well mixed low order bits. The \fBcompare\fR callback takes two arguments (pointers to two hash table entries), and returns 0 if their keys are equal, nonzero otherwise. .PP If your hash table will contain items of some particular type and the \fBhash\fR and \&\fBcompare\fR callbacks hash/compare these types, then the \&\fB\s-1IMPLEMENT_LHASH_HASH_FN\s0\fR and \fB\s-1IMPLEMENT_LHASH_COMP_FN\s0\fR macros can be used to create callback wrappers of the prototypes required by \&\fBlh_TYPE_new()\fR as shown in this example: .PP .Vb 11 \& /* \& * Implement the hash and compare functions; "stuff" can be any word. \& */ \& static unsigned long stuff_hash(const TYPE *a) \& { \& ... \& } \& static int stuff_cmp(const TYPE *a, const TYPE *b) \& { \& ... \& } \& \& /* \& * Implement the wrapper functions. \& */ \& static IMPLEMENT_LHASH_HASH_FN(stuff, TYPE) \& static IMPLEMENT_LHASH_COMP_FN(stuff, TYPE) .Ve .PP If the type is going to be used in several places, the following macros can be used in a common header file to declare the function wrappers: .PP .Vb 2 \& DECLARE_LHASH_HASH_FN(stuff, TYPE) \& DECLARE_LHASH_COMP_FN(stuff, TYPE) .Ve .PP Then a hash table of \s-1TYPE\s0 objects can be created using this: .PP .Vb 1 \& LHASH_OF(TYPE) *htable; \& \& htable = lh_TYPE_new(LHASH_HASH_FN(stuff), LHASH_COMP_FN(stuff)); .Ve .PP \&\fBlh_TYPE_free()\fR frees the \fB\s-1LHASH_OF\s0(\s-1TYPE\s0)\fR structure \&\fBtable\fR. Allocated hash table entries will not be freed; consider using \fBlh_TYPE_doall()\fR to deallocate any remaining entries in the hash table (see below). .PP \&\fBlh_TYPE_insert()\fR inserts the structure pointed to by \fBdata\fR into \&\fBtable\fR. If there already is an entry with the same key, the old value is replaced. Note that \fBlh_TYPE_insert()\fR stores pointers, the data are not copied. .PP \&\fBlh_TYPE_delete()\fR deletes an entry from \fBtable\fR. .PP \&\fBlh_TYPE_retrieve()\fR looks up an entry in \fBtable\fR. Normally, \fBdata\fR is a structure with the key field(s) set; the function will return a pointer to a fully populated structure. .PP \&\fBlh_TYPE_doall()\fR will, for every entry in the hash table, call \&\fBfunc\fR with the data item as its parameter. For example: .PP .Vb 2 \& /* Cleans up resources belonging to \*(Aqa\*(Aq (this is implemented elsewhere) */ \& void TYPE_cleanup_doall(TYPE *a); \& \& /* Implement a prototype\-compatible wrapper for "TYPE_cleanup" */ \& IMPLEMENT_LHASH_DOALL_FN(TYPE_cleanup, TYPE) \& \& /* Call "TYPE_cleanup" against all items in a hash table. */ \& lh_TYPE_doall(hashtable, LHASH_DOALL_FN(TYPE_cleanup)); \& \& /* Then the hash table itself can be deallocated */ \& lh_TYPE_free(hashtable); .Ve .PP When doing this, be careful if you delete entries from the hash table in your callbacks: the table may decrease in size, moving the item that you are currently on down lower in the hash table \- this could cause some entries to be skipped during the iteration. The second best solution to this problem is to set hash\->down_load=0 before you start (which will stop the hash table ever decreasing in size). The best solution is probably to avoid deleting items from the hash table inside a \*(L"doall\*(R" callback! .PP \&\fBlh_TYPE_doall_arg()\fR is the same as \fBlh_TYPE_doall()\fR except that \&\fBfunc\fR will be called with \fBarg\fR as the second argument and \fBfunc\fR should be of type \fB\s-1LHASH_DOALL_ARG_FN_TYPE\s0\fR (a callback prototype that is passed both the table entry and an extra argument). As with \&\fBlh_doall()\fR, you can instead choose to declare your callback with a prototype matching the types you are dealing with and use the declare/implement macros to create compatible wrappers that cast variables before calling your type-specific callbacks. An example of this is demonstrated here (printing all hash table entries to a \s-1BIO\s0 that is provided by the caller): .PP .Vb 2 \& /* Prints item \*(Aqa\*(Aq to \*(Aqoutput_bio\*(Aq (this is implemented elsewhere) */ \& void TYPE_print_doall_arg(const TYPE *a, BIO *output_bio); \& \& /* Implement a prototype\-compatible wrapper for "TYPE_print" */ \& static IMPLEMENT_LHASH_DOALL_ARG_FN(TYPE, const TYPE, BIO) \& \& /* Print out the entire hashtable to a particular BIO */ \& lh_TYPE_doall_arg(hashtable, LHASH_DOALL_ARG_FN(TYPE_print), BIO, \& logging_bio); .Ve .PP \&\fBlh_TYPE_error()\fR can be used to determine if an error occurred in the last operation. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBlh_TYPE_new()\fR returns \fB\s-1NULL\s0\fR on error, otherwise a pointer to the new \&\fB\s-1LHASH\s0\fR structure. .PP When a hash table entry is replaced, \fBlh_TYPE_insert()\fR returns the value being replaced. \fB\s-1NULL\s0\fR is returned on normal operation and on error. .PP \&\fBlh_TYPE_delete()\fR returns the entry being deleted. \fB\s-1NULL\s0\fR is returned if there is no such value in the hash table. .PP \&\fBlh_TYPE_retrieve()\fR returns the hash table entry if it has been found, \&\fB\s-1NULL\s0\fR otherwise. .PP \&\fBlh_TYPE_error()\fR returns 1 if an error occurred in the last operation, 0 otherwise. It's meaningful only after non-retrieve operations. .PP \&\fBlh_TYPE_free()\fR, \fBlh_TYPE_doall()\fR and \fBlh_TYPE_doall_arg()\fR return no values. .SH "NOTE" .IX Header "NOTE" The \s-1LHASH\s0 code is not thread safe. All updating operations, as well as lh_TYPE_error call must be performed under a write lock. All retrieve operations should be performed under a read lock, \fIunless\fR accurate usage statistics are desired. In which case, a write lock should be used for retrieve operations as well. For output of the usage statistics, using the functions from \fBOPENSSL_LH_stats\fR\|(3), a read lock suffices. .PP The \s-1LHASH\s0 code regards table entries as constant data. As such, it internally represents \fBlh_insert()\fR'd items with a \*(L"const void *\*(R" pointer type. This is why callbacks such as those used by \fBlh_doall()\fR and \fBlh_doall_arg()\fR declare their prototypes with \*(L"const\*(R", even for the parameters that pass back the table items' data pointers \- for consistency, user-provided data is \*(L"const\*(R" at all times as far as the \&\s-1LHASH\s0 code is concerned. However, as callers are themselves providing these pointers, they can choose whether they too should be treating all such parameters as constant. .PP As an example, a hash table may be maintained by code that, for reasons of encapsulation, has only \*(L"const\*(R" access to the data being indexed in the hash table (i.e. it is returned as \*(L"const\*(R" from elsewhere in their code) \- in this case the \s-1LHASH\s0 prototypes are appropriate as-is. Conversely, if the caller is responsible for the life-time of the data in question, then they may well wish to make modifications to table item passed back in the \fBlh_doall()\fR or \&\fBlh_doall_arg()\fR callbacks (see the \*(L"TYPE_cleanup\*(R" example above). If so, the caller can either cast the \*(L"const\*(R" away (if they're providing the raw callbacks themselves) or use the macros to declare/implement the wrapper functions without \*(L"const\*(R" types. .PP Callers that only have \*(L"const\*(R" access to data they're indexing in a table, yet declare callbacks without constant types (or cast the \&\*(L"const\*(R" away themselves), are therefore creating their own risks/bugs without being encouraged to do so by the \s-1API.\s0 On a related note, those auditing code should pay special attention to any instances of DECLARE/IMPLEMENT_LHASH_DOALL_[\s-1ARG_\s0]_FN macros that provide types without any \*(L"const\*(R" qualifiers. .SH "BUGS" .IX Header "BUGS" \&\fBlh_TYPE_insert()\fR returns \fB\s-1NULL\s0\fR both for success and error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBOPENSSL_LH_stats\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" In OpenSSL 1.0.0, the lhash interface was revamped for better type checking. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2022 The OpenSSL Project Authors.

This is accomplished by setting a built-in \s-1CT\s0 validation callback. The behaviour of the callback is determined by the \fBvalidation_mode\fR argument, which can be either of \fB\s-1SSL_CT_VALIDATION_PERMISSIVE\s0\fR or \&\fB\s-1SSL_CT_VALIDATION_STRICT\s0\fR as described below. .PP If \fBvalidation_mode\fR is equal to \fB\s-1SSL_CT_VALIDATION_STRICT\s0\fR, then in a full \&\s-1TLS\s0 handshake with the verification mode set to \fB\s-1SSL_VERIFY_PEER\s0\fR, if the peer presents no valid SCTs the handshake will be aborted. If the verification mode is \fB\s-1SSL_VERIFY_NONE\s0\fR, the handshake will continue despite lack of valid SCTs. However, in that case if the verification status before the built-in callback was \fBX509_V_OK\fR it will be set to \fBX509_V_ERR_NO_VALID_SCTS\fR after the callback. Applications can call \fBSSL_get_verify_result\fR\|(3) to check the status at handshake completion, even after session resumption since the verification status is part of the saved session state. See \fBSSL_set_verify\fR\|(3), <\fBSSL_get_verify_result\fR\|(3)>, \fBSSL_session_reused\fR\|(3). .PP If \fBvalidation_mode\fR is equal to \fB\s-1SSL_CT_VALIDATION_PERMISSIVE\s0\fR, then the handshake continues, and the verification status is not modified, regardless of the validation status of any SCTs. The application can still inspect the validation status of the SCTs at handshake completion. Note that with session resumption there will not be any SCTs presented during the handshake. Therefore, in applications that delay \s-1SCT\s0 policy enforcement until after handshake completion, such delayed \s-1SCT\s0 checks should only be performed when the session is not resumed. .PP \&\fBSSL_set_ct_validation_callback()\fR and \fBSSL_CTX_set_ct_validation_callback()\fR register a custom callback that may implement a different policy than either of the above. This callback can examine the peer's SCTs and determine whether they are sufficient to allow the connection to continue. The \s-1TLS\s0 handshake is aborted if the verification mode is not \fB\s-1SSL_VERIFY_NONE\s0\fR and the callback returns a non-positive result. .PP An arbitrary callback context argument, \fBarg\fR, can be passed in when setting the callback. This will be passed to the callback whenever it is invoked. Ownership of this context remains with the caller. .PP If no callback is set, SCTs will not be requested and Certificate Transparency validation will not occur. .PP No callback will be invoked when the peer presents no certificate, e.g. by employing an anonymous (aNULL) cipher suite. In that case the handshake continues as it would had no callback been requested. Callbacks are also not invoked when the peer certificate chain is invalid or validated via \s-1\fBDANE\-TA\s0\fR\|(2) or \s-1\fBDANE\-EE\s0\fR\|(3) \s-1TLSA\s0 records which use a private X.509 \&\s-1PKI,\s0 or no X.509 \s-1PKI\s0 at all, respectively. Clients that require SCTs are expected to not have enabled any aNULL ciphers nor to have specified server verification via \s-1\fBDANE\-TA\s0\fR\|(2) or \s-1\fBDANE\-EE\s0\fR\|(3) \s-1TLSA\s0 records. .PP \&\fBSSL_disable_ct()\fR and \fBSSL_CTX_disable_ct()\fR turn off \s-1CT\s0 processing, whether enabled via the built-in or the custom callbacks, by setting a \s-1NULL\s0 callback. These may be implemented as macros. .PP \&\fBSSL_ct_is_enabled()\fR and \fBSSL_CTX_ct_is_enabled()\fR return 1 if \s-1CT\s0 processing is enabled via either \fBSSL_enable_ct()\fR or a non-null custom callback, and 0 otherwise. .SH "NOTES" .IX Header "NOTES" When \s-1SCT\s0 processing is enabled, \s-1OCSP\s0 stapling will be enabled. This is because one possible source of SCTs is the \s-1OCSP\s0 response from a server. .PP The time returned by \fBSSL_SESSION_get_time()\fR will be used to evaluate whether any presented SCTs have timestamps that are in the future (and therefore invalid). .SH "RESTRICTIONS" .IX Header "RESTRICTIONS" Certificate Transparency validation cannot be enabled and so a callback cannot be set if a custom client extension handler has been registered to handle \s-1SCT\s0 extensions (\fBTLSEXT_TYPE_signed_certificate_timestamp\fR). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_enable_ct()\fR, \fBSSL_CTX_enable_ct()\fR, \fBSSL_CTX_set_ct_validation_callback()\fR and \&\fBSSL_set_ct_validation_callback()\fR return 1 if the \fBcallback\fR is successfully set.

Supported OpenSSL type object can be extracted using one of \&\fBSTORE_INFO_get0_TYPE()\fR. The life time of this extracted object is as long as the life time of the \fB\s-1OSSL_STORE_INFO\s0\fR it was extracted from, so care should be taken not to free the latter too early. As an alternative, \fBSTORE_INFO_get1_TYPE()\fR extracts a duplicate (or the same object with its reference count increased), which can be used after the containing \fB\s-1OSSL_STORE_INFO\s0\fR has been freed. The object returned by \fBSTORE_INFO_get1_TYPE()\fR must be freed separately by the caller. See \*(L"\s-1SUPPORTED OBJECTS\*(R"\s0 for more information on the types that are supported. .SS "Functions" .IX Subsection "Functions" \&\fBOSSL_STORE_INFO_get_type()\fR takes a \fB\s-1OSSL_STORE_INFO\s0\fR and returns the \s-1STORE\s0 type number for the object inside. \&\fBSTORE_INFO_get_type_string()\fR takes a \s-1STORE\s0 type number and returns a short string describing it. .PP \&\fBOSSL_STORE_INFO_get0_NAME()\fR, \fBOSSL_STORE_INFO_get0_NAME_description()\fR, \&\fBOSSL_STORE_INFO_get0_PARAMS()\fR, \fBOSSL_STORE_INFO_get0_PKEY()\fR, \&\fBOSSL_STORE_INFO_get0_CERT()\fR and \fBOSSL_STORE_INFO_get0_CRL()\fR all take a \&\fB\s-1OSSL_STORE_INFO\s0\fR and return the held object of the appropriate OpenSSL type provided that's what's held. .PP \&\fBOSSL_STORE_INFO_get1_NAME()\fR, \fBOSSL_STORE_INFO_get1_NAME_description()\fR, \&\fBOSSL_STORE_INFO_get1_PARAMS()\fR, \fBOSSL_STORE_INFO_get1_PKEY()\fR, \&\fBOSSL_STORE_INFO_get1_CERT()\fR and \fBOSSL_STORE_INFO_get1_CRL()\fR all take a \&\fB\s-1OSSL_STORE_INFO\s0\fR and return a duplicate of the held object of the appropriate OpenSSL type provided that's what's held. .PP \&\fBOSSL_STORE_INFO_free()\fR frees a \fB\s-1OSSL_STORE_INFO\s0\fR and its contained type. .PP \&\fBOSSL_STORE_INFO_new_NAME()\fR , \fBOSSL_STORE_INFO_new_PARAMS()\fR, \&\fBOSSL_STORE_INFO_new_PKEY()\fR, \fBOSSL_STORE_INFO_new_CERT()\fR and \&\fBOSSL_STORE_INFO_new_CRL()\fR create a \fB\s-1OSSL_STORE_INFO\s0\fR object to hold the given input object.

This can be applied to all schemes that can somehow support a listing of object URIs. .Sp For \f(CW\*(C`file:\*(C'\fR URIs that are used without the explicit scheme, the returned name will be the path of each object, so if \f(CW\*(C`/foo/bar\*(C'\fR was given and that path has the file \f(CW\*(C`cookie.pem\*(C'\fR, the name \&\f(CW\*(C`/foo/bar/cookie.pem\*(C'\fR will be returned. .Sp The returned \s-1URI\s0 is considered canonical and must be unique and permanent for the storage where the object (or collection of objects) resides. Each loader is responsible for ensuring that it only returns canonical URIs. However, it's possible that certain schemes allow an object (or collection thereof) to be reached with alternative URIs; just because one \s-1URI\s0 is canonical doesn't mean that other variants can't be used. .Sp At the discretion of the loader that was used to get these names, an extra description may be attached as well. .IP "\s-1OSSL_STORE_INFO_PARAMS\s0" 4 .IX Item "OSSL_STORE_INFO_PARAMS" Key parameters. .IP "\s-1OSSL_STORE_INFO_PKEY\s0" 4 .IX Item "OSSL_STORE_INFO_PKEY" A private/public key of some sort. .IP "\s-1OSSL_STORE_INFO_CERT\s0" 4 .IX Item "OSSL_STORE_INFO_CERT" An X.509 certificate. .IP "\s-1OSSL_STORE_INFO_CRL\s0" 4 .IX Item "OSSL_STORE_INFO_CRL" A X.509 certificate revocation list. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOSSL_STORE_INFO_get_type()\fR returns the \s-1STORE\s0 type number of the given \&\fB\s-1OSSL_STORE_INFO\s0\fR.

If a ClientHello is received that does not contain a cookie, then they respond with a request for a new ClientHello that does contain a cookie. If a ClientHello is received with a cookie that is verified then the function returns in order to enable the handshake to be completed (for example by using \fBSSL_accept()\fR). .SH "NOTES" .IX Header "NOTES" Some transport protocols (such as \s-1UDP\s0) can be susceptible to amplification attacks. Unlike \s-1TCP\s0 there is no initial connection setup in \s-1UDP\s0 that validates that the client can actually receive messages on its advertised source address. An attacker could forge its source \s-1IP\s0 address and then send handshake initiation messages to the server. The server would then send its response to the forged source \s-1IP.\s0 If the response messages are larger than the original message then the amplification attack has succeeded. .PP If \s-1DTLS\s0 is used over \s-1UDP\s0 (or any datagram based protocol that does not validate the source \s-1IP\s0) then it is susceptible to this type of attack. TLSv1.3 is designed to operate over a stream-based transport protocol (such as \s-1TCP\s0). If \s-1TCP\s0 is being used then there is no need to use \fBSSL_stateless()\fR. However, some stream-based transport protocols (e.g. \s-1QUIC\s0) may not validate the source address. In this case a TLSv1.3 application would be susceptible to this attack. .PP As a countermeasure to this issue TLSv1.3 and \s-1DTLS\s0 include a stateless cookie mechanism. The idea is that when a client attempts to connect to a server it sends a ClientHello message. The server responds with a HelloRetryRequest (in TLSv1.3) or a HelloVerifyRequest (in \s-1DTLS\s0) which contains a unique cookie. The client then resends the ClientHello, but this time includes the cookie in the message thus proving that the client is capable of receiving messages sent to that address. All of this can be done by the server without allocating any state, and thus without consuming expensive resources. .PP OpenSSL implements this capability via the \fBSSL_stateless()\fR and \fBDTLSv1_listen()\fR functions. The \fBssl\fR parameter should be a newly allocated \s-1SSL\s0 object with its read and write BIOs set, in the same way as might be done for a call to \&\fBSSL_accept()\fR. Typically, for \s-1DTLS,\s0 the read \s-1BIO\s0 will be in an \*(L"unconnected\*(R" state and thus capable of receiving messages from any peer. .PP When a ClientHello is received that contains a cookie that has been verified, then these functions will return with the \fBssl\fR parameter updated into a state where the handshake can be continued by a call to (for example) \fBSSL_accept()\fR. Additionally, for \fBDTLSv1_listen()\fR, the \fB\s-1BIO_ADDR\s0\fR pointed to by \fBpeer\fR will be filled in with details of the peer that sent the ClientHello. If the underlying \&\s-1BIO\s0 is unable to obtain the \fB\s-1BIO_ADDR\s0\fR of the peer (for example because the \s-1BIO\s0 does not support this), then \fB*peer\fR will be cleared and the family set to \&\s-1AF_UNSPEC.\s0 Typically user code is expected to \*(L"connect\*(R" the underlying socket to the peer and continue the handshake in a connected state. .PP Prior to calling \fBDTLSv1_listen()\fR user code must ensure that cookie generation and verification callbacks have been set up using \&\fBSSL_CTX_set_cookie_generate_cb\fR\|(3) and \fBSSL_CTX_set_cookie_verify_cb\fR\|(3) respectively. For \fBSSL_stateless()\fR, \fBSSL_CTX_set_stateless_cookie_generate_cb\fR\|(3) and \fBSSL_CTX_set_stateless_cookie_verify_cb\fR\|(3) must be used instead. .PP Since \fBDTLSv1_listen()\fR operates entirely statelessly whilst processing incoming ClientHellos it is unable to process fragmented messages (since this would require the allocation of state). An implication of this is that \fBDTLSv1_listen()\fR \&\fBonly\fR supports ClientHellos that fit inside a single datagram. .PP For \fBSSL_stateless()\fR if an entire ClientHello message cannot be read without the \&\*(L"read\*(R" \s-1BIO\s0 becoming empty then the \fBSSL_stateless()\fR call will fail. It is the application's responsibility to ensure that data read from the \*(L"read\*(R" \s-1BIO\s0 during a single \fBSSL_stateless()\fR call is all from the same peer. .PP \&\fBSSL_stateless()\fR will fail (with a 0 return value) if some \s-1TLS\s0 version less than TLSv1.3 is used. .PP Both \fBSSL_stateless()\fR and \fBDTLSv1_listen()\fR will clear the error queue when they start. .SH "RETURN VALUES" .IX Header "RETURN VALUES" For \fBSSL_stateless()\fR a return value of 1 indicates success and the \fBssl\fR object will be set up ready to continue the handshake. A return value of 0 or \-1 indicates failure. If the value is 0 then a HelloRetryRequest was sent. A value of \-1 indicates any other error. User code may retry the \fBSSL_stateless()\fR call. .PP For \fBDTLSv1_listen()\fR a return value of >= 1 indicates success. The \fBssl\fR object will be set up ready to continue the handshake. the \fBpeer\fR value will also be filled in. .PP A return value of 0 indicates a non-fatal error. This could (for example) be because of nonblocking \s-1IO,\s0 or some invalid message having been received from a peer. Errors may be placed on the OpenSSL error queue with further information if appropriate. Typically user code is expected to retry the call to \fBDTLSv1_listen()\fR in the event of a non-fatal error. .PP A return value of <0 indicates a fatal error. This could (for example) be because of a failure to allocate sufficient memory for the operation. .PP For \fBDTLSv1_listen()\fR, prior to OpenSSL 1.1.0, fatal and non-fatal errors both produce return codes <= 0 (in typical implementations user code treats all errors as non-fatal), whilst return codes >0 indicate success. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CTX_set_cookie_generate_cb\fR\|(3), \fBSSL_CTX_set_cookie_verify_cb\fR\|(3), \&\fBSSL_CTX_set_stateless_cookie_generate_cb\fR\|(3), \&\fBSSL_CTX_set_stateless_cookie_verify_cb\fR\|(3), \fBSSL_get_error\fR\|(3), \&\fBSSL_accept\fR\|(3), \fBssl\fR\|(7), \fBbio\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" The \fBSSL_stateless()\fR function was added in OpenSSL 1.1.1. .PP The \fBDTLSv1_listen()\fR return codes were clarified in OpenSSL 1.1.0.

For convenience, OIDs are usually represented in source code as numeric identifiers, or \fI\s-1NID\s0\fRs. OpenSSL has an internal table of OIDs that are generated when the library is built, and their corresponding NIDs are available as defined constants. For the functions below, application code should treat all returned values \*(-- OIDs, NIDs, or names \*(-- as constants. .PP \&\fBOBJ_nid2obj()\fR, \fBOBJ_nid2ln()\fR and \fBOBJ_nid2sn()\fR convert the \s-1NID\s0 \fIn\fR to an \s-1ASN1_OBJECT\s0 structure, its long name and its short name respectively, or \fB\s-1NULL\s0\fR if an error occurred. .PP \&\fBOBJ_obj2nid()\fR, \fBOBJ_ln2nid()\fR, \fBOBJ_sn2nid()\fR return the corresponding \s-1NID\s0 for the object \fIo\fR, the long name <ln> or the short name <sn> respectively or NID_undef if an error occurred. .PP \&\fBOBJ_txt2nid()\fR returns \s-1NID\s0 corresponding to text string \fIs\fR. \fIs\fR can be a long name, a short name or the numerical representation of an object. .PP \&\fBOBJ_txt2obj()\fR converts the text string \fIs\fR into an \s-1ASN1_OBJECT\s0 structure. If \fIno_name\fR is 0 then long names and short names will be interpreted as well as numerical forms. If \fIno_name\fR is 1 only the numerical form is acceptable. .PP \&\fBOBJ_obj2txt()\fR converts the \fB\s-1ASN1_OBJECT\s0\fR \fIa\fR into a textual representation. Unless \fIbuf\fR is \s-1NULL,\s0 the representation is written as a NUL-terminated string to \fIbuf\fR, where at most \fIbuf_len\fR bytes are written, truncating the result if necessary. In any case it returns the total string length, excluding the \s-1NUL\s0 character, required for non-truncated representation, or \-1 on error. If \fIno_name\fR is 0 then if the object has a long or short name then that will be used, otherwise the numerical form will be used. If \fIno_name\fR is 1 then the numerical form will always be used. .PP \&\fBi2t_ASN1_OBJECT()\fR is the same as \fBOBJ_obj2txt()\fR with the \fIno_name\fR set to zero. .PP \&\fBOBJ_cmp()\fR compares \fIa\fR to \fIb\fR. If the two are identical 0 is returned. .PP \&\fBOBJ_dup()\fR returns a copy of \fIo\fR. .PP \&\fBOBJ_create()\fR adds a new object to the internal table. \fIoid\fR is the numerical form of the object, \fIsn\fR the short name and \fIln\fR the long name. A new \s-1NID\s0 is returned for the created object in case of success and NID_undef in case of failure. .PP \&\fBOBJ_length()\fR returns the size of the content octets of \fIobj\fR. .PP \&\fBOBJ_get0_data()\fR returns a pointer to the content octets of \fIobj\fR. The returned pointer is an internal pointer which \fBmust not\fR be freed. .PP \&\fBOBJ_cleanup()\fR releases any resources allocated by creating new objects. .SH "NOTES" .IX Header "NOTES" Objects in OpenSSL can have a short name, a long name and a numerical identifier (\s-1NID\s0) associated with them. A standard set of objects is represented in an internal table. The appropriate values are defined in the header file \fBobjects.h\fR. .PP For example the \s-1OID\s0 for commonName has the following definitions: .PP .Vb 3 \& #define SN_commonName "CN" \& #define LN_commonName "commonName" \& #define NID_commonName 13 .Ve .PP New objects can be added by calling \fBOBJ_create()\fR. .PP Table objects have certain advantages over other objects: for example their NIDs can be used in a C language switch statement. They are also static constant structures which are shared: that is there is only a single constant structure for each table object. .PP Objects which are not in the table have the \s-1NID\s0 value NID_undef. .PP Objects do not need to be in the internal tables to be processed, the functions \fBOBJ_txt2obj()\fR and \fBOBJ_obj2txt()\fR can process the numerical form of an \s-1OID.\s0 .PP Some objects are used to represent algorithms which do not have a corresponding \s-1ASN.1 OBJECT IDENTIFIER\s0 encoding (for example no \s-1OID\s0 currently exists for a particular algorithm). As a result they \fBcannot\fR be encoded or decoded as part of \s-1ASN.1\s0 structures. Applications can determine if there is a corresponding \s-1OBJECT IDENTIFIER\s0 by checking \fBOBJ_length()\fR is not zero. .PP These functions cannot return \fBconst\fR because an \fB\s-1ASN1_OBJECT\s0\fR can represent both an internal, constant, \s-1OID\s0 and a dynamically-created one. The latter cannot be constant because it needs to be freed after use. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOBJ_nid2obj()\fR returns an \fB\s-1ASN1_OBJECT\s0\fR structure or \fB\s-1NULL\s0\fR is an error occurred. .PP \&\fBOBJ_nid2ln()\fR and \fBOBJ_nid2sn()\fR returns a valid string or \fB\s-1NULL\s0\fR on error. .PP \&\fBOBJ_obj2nid()\fR, \fBOBJ_ln2nid()\fR, \fBOBJ_sn2nid()\fR and \fBOBJ_txt2nid()\fR return a \s-1NID\s0 or \fBNID_undef\fR on error. .PP \&\fBOBJ_add_sigid()\fR returns 1 on success or 0 on error. .PP \&\fBi2t_ASN1_OBJECT()\fR an \fBOBJ_obj2txt()\fR return \-1 on error. On success, they return the length of the string written to \fIbuf\fR if \fIbuf\fR is not \s-1NULL\s0 and \fIbuf_len\fR is big enough, otherwise the total string length.

It admits multiple lookup mechanisms and efficient scaling performance with large numbers of certificates, and a great deal of flexibility in how validation and policy checks are performed. .PP \&\fBX509_STORE_new\fR\|(3) creates an empty \fBX509_STORE\fR structure, which contains no information about trusted certificates or where such certificates are located on disk, and is generally not usable. Normally, trusted certificates will be added to the \fBX509_STORE\fR to prepare it for use, via mechanisms such as \fBX509_STORE_add_lookup()\fR and \fBX509_LOOKUP_file()\fR, or \&\fBPEM_read_bio_X509_AUX()\fR and \fBX509_STORE_add_cert()\fR. CRLs can also be added, and many behaviors configured as desired. .PP Once the \fBX509_STORE\fR is suitably configured, \fBX509_STORE_CTX_new()\fR is used to instantiate a single-use \fBX509_STORE_CTX\fR for each chain-building and verification operation. That process includes providing the end-entity certificate to be verified and an additional set of untrusted certificates that may be used in chain-building. As such, it is expected that the certificates included in the \fBX509_STORE\fR are certificates that represent trusted entities such as root certificate authorities (CAs). OpenSSL represents these trusted certificates internally as \fBX509\fR objects with an associated \fBX509_CERT_AUX\fR, as are produced by \&\fBPEM_read_bio_X509_AUX()\fR and similar routines that refer to X509_AUX. The public interfaces that operate on such trusted certificates still operate on pointers to \fBX509\fR objects, though. .PP \&\fBX509_STORE_add_cert()\fR and \fBX509_STORE_add_crl()\fR add the respective object to the \fBX509_STORE\fR's local storage. Untrusted objects should not be added in this way. The added object's reference count is incremented by one, hence the caller retains ownership of the object and needs to free it when it is no longer needed. .PP \&\fBX509_STORE_set_depth()\fR, \fBX509_STORE_set_flags()\fR, \fBX509_STORE_set_purpose()\fR, \&\fBX509_STORE_set_trust()\fR, and \fBX509_STORE_set1_param()\fR set the default values for the corresponding values used in certificate chain validation. Their behavior is documented in the corresponding \fBX509_VERIFY_PARAM\fR manual pages, e.g., \fBX509_VERIFY_PARAM_set_depth\fR\|(3). .PP \&\fBX509_STORE_add_lookup()\fR finds or creates a \fBX509_LOOKUP\fR\|(3) with the \&\fBX509_LOOKUP_METHOD\fR\|(3) \fImeth\fR and adds it to the \fBX509_STORE\fR \&\fIstore\fR. This also associates the \fBX509_STORE\fR with the lookup, so \&\fBX509_LOOKUP\fR functions can look up objects in that store. .PP \&\fBX509_STORE_load_locations()\fR loads trusted certificate(s) into an \&\fBX509_STORE\fR from a given file and/or directory path. It is permitted to specify just a file, just a directory, or both paths. The certificates in the directory must be in hashed form, as documented in \&\fBX509_LOOKUP_hash_dir\fR\|(3). .PP \&\fBX509_STORE_set_default_paths()\fR is somewhat misnamed, in that it does not set what default paths should be used for loading certificates. Instead, it loads certificates into the \fBX509_STORE\fR from the hardcoded default paths. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBX509_STORE_add_cert()\fR, \fBX509_STORE_add_crl()\fR, \fBX509_STORE_set_depth()\fR, \&\fBX509_STORE_set_flags()\fR, \fBX509_STORE_set_purpose()\fR, \&\fBX509_STORE_set_trust()\fR, \fBX509_STORE_load_locations()\fR, and \&\fBX509_STORE_set_default_paths()\fR return 1 on success or 0 on failure. .PP \&\fBX509_STORE_add_lookup()\fR returns the found or created \&\fBX509_LOOKUP\fR\|(3), or \s-1NULL\s0 on error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBX509_LOOKUP_hash_dir\fR\|(3). \&\fBX509_VERIFY_PARAM_set_depth\fR\|(3). \&\fBX509_STORE_new\fR\|(3), \&\fBX509_STORE_get0_param\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2017\-2020 The OpenSSL Project Authors.

This means that calls to \fBEVP_VerifyUpdate()\fR and \fBEVP_VerifyFinal()\fR can be called later to digest and verify additional data. .PP Since only a copy of the digest context is ever finalized the context must be cleaned up after use by calling \fBEVP_MD_CTX_free()\fR or a memory leak will occur. .SH "BUGS" .IX Header "BUGS" Older versions of this documentation wrongly stated that calls to \&\fBEVP_VerifyUpdate()\fR could not be made after calling \fBEVP_VerifyFinal()\fR. .PP Since the public key is passed in the call to \fBEVP_SignFinal()\fR any error relating to the private key (for example an unsuitable key and digest combination) will not be indicated until after potentially large amounts of data have been passed through \fBEVP_SignUpdate()\fR. .PP It is not possible to change the signing parameters using these function. .PP The previous two bugs are fixed in the newer EVP_DigestVerify*() function. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBevp\fR\|(7), \&\fBEVP_SignInit\fR\|(3), \&\fBEVP_DigestInit\fR\|(3), \&\fBevp\fR\|(7), \s-1\fBHMAC\s0\fR\|(3), \s-1\fBMD2\s0\fR\|(3), \&\s-1\fBMD5\s0\fR\|(3), \s-1\fBMDC2\s0\fR\|(3), \s-1\fBRIPEMD160\s0\fR\|(3), \&\s-1\fBSHA1\s0\fR\|(3), \fBdgst\fR\|(1) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

The options are coded as bit masks and can be combined by a bitwise \fBor\fR operation (|). .PP \&\fBSSL_CTX_set_options()\fR and \fBSSL_set_options()\fR affect the (external) protocol behaviour of the \s-1SSL\s0 library. The (internal) behaviour of the \s-1API\s0 can be changed by using the similar \&\fBSSL_CTX_set_mode\fR\|(3) and \fBSSL_set_mode()\fR functions. .PP During a handshake, the option settings of the \s-1SSL\s0 object are used. When a new \s-1SSL\s0 object is created from a context using \fBSSL_new()\fR, the current option setting is copied. Changes to \fBctx\fR do not affect already created \&\s-1SSL\s0 objects. \fBSSL_clear()\fR does not affect the settings. .PP The following \fBbug workaround\fR options are available: .IP "\s-1SSL_OP_SAFARI_ECDHE_ECDSA_BUG\s0" 4 .IX Item "SSL_OP_SAFARI_ECDHE_ECDSA_BUG" Don't prefer ECDHE-ECDSA ciphers when the client appears to be Safari on \s-1OS X. OS X 10.8..10.8.3\s0 has broken support for ECDHE-ECDSA ciphers. .IP "\s-1SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS\s0" 4 .IX Item "SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS" Disables a countermeasure against a \s-1SSL 3.0/TLS 1.0\s0 protocol vulnerability affecting \s-1CBC\s0 ciphers, which cannot be handled by some broken \s-1SSL\s0 implementations.

Some clients violate this rule by adapting to the server's answer. (Example: the client sends a SSLv2 hello and accepts up to SSLv3.1=TLSv1, the server only understands up to SSLv3. In this case the client must still use the same SSLv3.1=TLSv1 announcement. Some clients step down to SSLv3 with respect to the server's answer and violate the version rollback protection.) .IP "\s-1SSL_OP_CIPHER_SERVER_PREFERENCE\s0" 4 .IX Item "SSL_OP_CIPHER_SERVER_PREFERENCE" When choosing a cipher, use the server's preferences instead of the client preferences.

Only affects \&\s-1DTLS\s0 connections. .IP "\s-1SSL_OP_NO_TICKET\s0" 4 .IX Item "SSL_OP_NO_TICKET" \&\s-1SSL/TLS\s0 supports two mechanisms for resuming sessions: session ids and stateless session tickets. .Sp When using session ids a copy of the session information is cached on the server and a unique id is sent to the client. When the client wishes to resume it provides the unique id so that the server can retrieve the session information from its cache. .Sp When using stateless session tickets the server uses a session ticket encryption key to encrypt the session information. This encrypted data is sent to the client as a \*(L"ticket\*(R". When the client wishes to resume it sends the encrypted data back to the server. The server uses its key to decrypt the data and resume the session. In this way the server can operate statelessly \- no session information needs to be cached locally. .Sp The TLSv1.3 protocol only supports tickets and does not directly support session ids. However, OpenSSL allows two modes of ticket operation in TLSv1.3: stateful and stateless. Stateless tickets work the same way as in TLSv1.2 and below. Stateful tickets mimic the session id behaviour available in TLSv1.2 and below. The session information is cached on the server and the session id is wrapped up in a ticket and sent back to the client. When the client wishes to resume, it presents a ticket in the same way as for stateless tickets. The server can then extract the session id from the ticket and retrieve the session information from its cache. .Sp By default OpenSSL will use stateless tickets. The \s-1SSL_OP_NO_TICKET\s0 option will cause stateless tickets to not be issued. In TLSv1.2 and below this means no ticket gets sent to the client at all. In TLSv1.3 a stateful ticket will be sent. This is a server-side option only. .Sp In TLSv1.3 it is possible to suppress all tickets (stateful and stateless) from being sent by calling \fBSSL_CTX_set_num_tickets\fR\|(3) or \&\fBSSL_set_num_tickets\fR\|(3). .IP "\s-1SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION\s0" 4 .IX Item "SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION" Allow legacy insecure renegotiation between OpenSSL and unpatched clients or servers.

This helps those clients (e.g. mobile) use ChaCha20\-Poly1305 if that cipher is anywhere in the server cipher list; but still allows other clients to use \s-1AES\s0 and other ciphers.

This has the effect of making TLSv1.3 look more like TLSv1.2 so that middleboxes that do not understand TLSv1.3 will not drop the connection. Regardless of whether this option is set or not \s-1CCS\s0 messages received from the peer will always be ignored in TLSv1.3. This option is set by default.

Some applications may be able to mitigate the replay risks in other ways and in such cases the built in OpenSSL functionality is not required.

In the description below an implementation supporting secure renegotiation is referred to as \fIpatched\fR. A server not supporting secure renegotiation is referred to as \fIunpatched\fR. .PP The following sections describe the operations permitted by OpenSSL's secure renegotiation implementation. .SS "Patched client and server" .IX Subsection "Patched client and server" Connections and renegotiation are always permitted by OpenSSL implementations. .SS "Unpatched client and patched OpenSSL server" .IX Subsection "Unpatched client and patched OpenSSL server" The initial connection succeeds but client renegotiation is denied by the server with a \fBno_renegotiation\fR warning alert if \s-1TLS\s0 v1.0 is used or a fatal \&\fBhandshake_failure\fR alert in \s-1SSL\s0 v3.0. .PP If the patched OpenSSL server attempts to renegotiate a fatal \&\fBhandshake_failure\fR alert is sent. This is because the server code may be unaware of the unpatched nature of the client. .PP If the option \fB\s-1SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION\s0\fR is set then renegotiation \fBalways\fR succeeds. .SS "Patched OpenSSL client and unpatched server." .IX Subsection "Patched OpenSSL client and unpatched server." If the option \fB\s-1SSL_OP_LEGACY_SERVER_CONNECT\s0\fR or \&\fB\s-1SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION\s0\fR is set then initial connections and renegotiation between patched OpenSSL clients and unpatched servers succeeds. If neither option is set then initial connections to unpatched servers will fail. .PP The option \fB\s-1SSL_OP_LEGACY_SERVER_CONNECT\s0\fR is currently set by default even though it has security implications: otherwise it would be impossible to connect to unpatched servers (i.e. all of them initially) and this is clearly not acceptable. Renegotiation is permitted because this does not add any additional security issues: during an attack clients do not see any renegotiations anyway. .PP As more servers become patched the option \fB\s-1SSL_OP_LEGACY_SERVER_CONNECT\s0\fR will \&\fBnot\fR be set by default in a future version of OpenSSL. .PP OpenSSL client applications wishing to ensure they can connect to unpatched servers should always \fBset\fR \fB\s-1SSL_OP_LEGACY_SERVER_CONNECT\s0\fR .PP OpenSSL client applications that want to ensure they can \fBnot\fR connect to unpatched servers (and thus avoid any security issues) should always \fBclear\fR \&\fB\s-1SSL_OP_LEGACY_SERVER_CONNECT\s0\fR using \fBSSL_CTX_clear_options()\fR or \&\fBSSL_clear_options()\fR. .PP The difference between the \fB\s-1SSL_OP_LEGACY_SERVER_CONNECT\s0\fR and \&\fB\s-1SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION\s0\fR options is that \&\fB\s-1SSL_OP_LEGACY_SERVER_CONNECT\s0\fR enables initial connections and secure renegotiation between OpenSSL clients and unpatched servers \fBonly\fR, while \&\fB\s-1SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION\s0\fR allows initial connections and renegotiation between OpenSSL and unpatched clients or servers. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set_options()\fR and \fBSSL_set_options()\fR return the new options bit mask after adding \fBoptions\fR. .PP \&\fBSSL_CTX_clear_options()\fR and \fBSSL_clear_options()\fR return the new options bit mask after clearing \fBoptions\fR. .PP \&\fBSSL_CTX_get_options()\fR and \fBSSL_get_options()\fR return the current bit mask. .PP \&\fBSSL_get_secure_renegotiation_support()\fR returns 1 is the peer supports secure renegotiation and 0 if it does not. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_new\fR\|(3), \fBSSL_clear\fR\|(3), \&\fBSSL_CTX_set_tmp_dh_callback\fR\|(3), \&\fBSSL_CTX_set_min_proto_version\fR\|(3), \&\fBdhparam\fR\|(1) .SH "HISTORY" .IX Header "HISTORY" The attempt to always try to use secure renegotiation was added in OpenSSL 0.9.8m. .PP The \fB\s-1SSL_OP_PRIORITIZE_CHACHA\s0\fR and \fB\s-1SSL_OP_NO_RENEGOTIATION\s0\fR options were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2020 The OpenSSL Project Authors.

These \s-1CA\s0 certificates are made available via lookup methods, handled inside the X509_STORE. From the X509_STORE the X509_STORE_CTX used when verifying certificates is created. .PP Typically the trusted certificate store is handled indirectly via using \&\fBSSL_CTX_load_verify_locations\fR\|(3). Using the \fBSSL_CTX_set_cert_store()\fR and \fBSSL_CTX_get_cert_store()\fR functions it is possible to manipulate the X509_STORE object beyond the \&\fBSSL_CTX_load_verify_locations\fR\|(3) call. .PP Currently no detailed documentation on how to use the X509_STORE object is available. Not all members of the X509_STORE are used when the verification takes place. So will e.g. the \fBverify_callback()\fR be overridden with the \fBverify_callback()\fR set via the \&\fBSSL_CTX_set_verify\fR\|(3) family of functions. This document must therefore be updated when documentation about the X509_STORE object and its handling becomes available. .PP \&\fBSSL_CTX_set_cert_store()\fR does not increment the \fBstore\fR's reference count, so it should not be used to assign an X509_STORE that is owned by another \s-1SSL_CTX.\s0 .PP To share X509_STOREs between two SSL_CTXs, use \fBSSL_CTX_get_cert_store()\fR to get the X509_STORE from the first \s-1SSL_CTX,\s0 and then use \&\fBSSL_CTX_set1_cert_store()\fR to assign to the second \s-1SSL_CTX\s0 and increment the reference count of the X509_STORE. .SH "RESTRICTIONS" .IX Header "RESTRICTIONS" The X509_STORE structure used by an \s-1SSL_CTX\s0 is used for verifying peer certificates and building certificate chains, it is also shared by every child \s-1SSL\s0 structure.

Individual connections associated with the context can then enable per-connection \s-1DANE\s0 support as appropriate. \&\s-1DANE\s0 authentication is implemented in the \fBX509_verify_cert\fR\|(3) function, and applications that override \fBX509_verify_cert\fR\|(3) via \&\fBSSL_CTX_set_cert_verify_callback\fR\|(3) are responsible to authenticate the peer chain in whatever manner they see fit. .PP \&\fBSSL_CTX_dane_mtype_set()\fR may then be called zero or more times to adjust the supported digest algorithms. This must be done before any \s-1SSL\s0 handles are created for the context. .PP The \fBmtype\fR argument specifies a \s-1DANE TLSA\s0 matching type and the \fBmd\fR argument specifies the associated digest algorithm handle. The \fBord\fR argument specifies a strength ordinal. Algorithms with a larger strength ordinal are considered more secure. Strength ordinals are used to implement \s-1RFC7671\s0 digest algorithm agility. Specifying a \fB\s-1NULL\s0\fR digest algorithm for a matching type disables support for that matching type. Matching type \fBFull\fR\|(0) cannot be modified or disabled. .PP By default, matching type \f(CW\*(C`SHA2\-256(1)\*(C'\fR (see \s-1RFC7218\s0 for definitions of the \s-1DANE TLSA\s0 parameter acronyms) is mapped to \f(CW\*(C`EVP_sha256()\*(C'\fR with a strength ordinal of \f(CW1\fR and matching type \f(CW\*(C`SHA2\-512(2)\*(C'\fR is mapped to \f(CW\*(C`EVP_sha512()\*(C'\fR with a strength ordinal of \f(CW2\fR. .PP \&\fBSSL_dane_enable()\fR must be called before the \s-1SSL\s0 handshake is initiated with \&\fBSSL_connect\fR\|(3) if (and only if) you want to enable \s-1DANE\s0 for that connection. (The connection must be associated with a DANE-enabled \s-1SSL\s0 context). The \fBbasedomain\fR argument specifies the \s-1RFC7671 TLSA\s0 base domain, which will be the primary peer reference identifier for certificate name checks. Additional server names can be specified via \fBSSL_add1_host\fR\|(3). The \fBbasedomain\fR is used as the default \s-1SNI\s0 hint if none has yet been specified via \fBSSL_set_tlsext_host_name\fR\|(3). .PP \&\fBSSL_dane_tlsa_add()\fR may then be called one or more times, to load each of the \&\s-1TLSA\s0 records that apply to the remote \s-1TLS\s0 peer. (This too must be done prior to the beginning of the \s-1SSL\s0 handshake). The arguments specify the fields of the \s-1TLSA\s0 record. The \fBdata\fR field is provided in binary (wire \s-1RDATA\s0) form, not the hexadecimal \&\s-1ASCII\s0 presentation form, with an explicit length passed via \fBdlen\fR. The library takes a copy of the \fBdata\fR buffer contents and the caller may free the original \fBdata\fR buffer when convenient. A return value of 0 indicates that \*(L"unusable\*(R" \s-1TLSA\s0 records (with invalid or unsupported parameters) were provided. A negative return value indicates an internal error in processing the record. .PP The caller is expected to check the return value of each \fBSSL_dane_tlsa_add()\fR call and take appropriate action if none are usable or an internal error is encountered in processing some records. .PP If no \s-1TLSA\s0 records are added successfully, \s-1DANE\s0 authentication is not enabled, and authentication will be based on any configured traditional trust-anchors; authentication success in this case does not mean that the peer was DANE-authenticated. .PP \&\fBSSL_get0_dane_authority()\fR can be used to get more detailed information about the matched \s-1DANE\s0 trust-anchor after successful connection completion. The return value is negative if \s-1DANE\s0 verification failed (or was not enabled), 0 if an \s-1EE TLSA\s0 record directly matched the leaf certificate, or a positive number indicating the depth at which a \s-1TA\s0 record matched an issuer certificate. The complete verified chain can be retrieved via \fBSSL_get0_verified_chain\fR\|(3). The return value is an index into this verified chain, rather than the list of certificates sent by the peer as returned by \fBSSL_get_peer_cert_chain\fR\|(3). .PP If the \fBmcert\fR argument is not \fB\s-1NULL\s0\fR and a \s-1TLSA\s0 record matched a chain certificate, a pointer to the matching certificate is returned via \fBmcert\fR. The returned address is a short-term internal reference to the certificate and must not be freed by the application. Applications that want to retain access to the certificate can call \&\fBX509_up_ref\fR\|(3) to obtain a long-term reference which must then be freed via \&\fBX509_free\fR\|(3) once no longer needed. .PP If no \s-1TLSA\s0 records directly matched any elements of the certificate chain, but a \s-1\fBDANE\-TA\s0\fR\|(2) \s-1\fBSPKI\s0\fR\|(1) \fBFull\fR\|(0) record provided the public key that signed an element of the chain, then that key is returned via \fBmspki\fR argument (if not \&\s-1NULL\s0). In this case the return value is the depth of the top-most element of the validated certificate chain. As with \fBmcert\fR this is a short-term internal reference, and \&\fBEVP_PKEY_up_ref\fR\|(3) and \fBEVP_PKEY_free\fR\|(3) can be used to acquire and release long-term references respectively. .PP \&\fBSSL_get0_dane_tlsa()\fR can be used to retrieve the fields of the \s-1TLSA\s0 record that matched the peer certificate chain. The return value indicates the match depth or failure to match just as with \&\fBSSL_get0_dane_authority()\fR. When the return value is nonnegative, the storage pointed to by the \fBusage\fR, \&\fBselector\fR, \fBmtype\fR and \fBdata\fR parameters is updated to the corresponding \&\s-1TLSA\s0 record fields. The \fBdata\fR field is in binary wire form, and is therefore not NUL-terminated, its length is returned via the \fBdlen\fR parameter. If any of these parameters is \s-1NULL,\s0 the corresponding field is not returned. The \fBdata\fR parameter is set to a short-term internal-copy of the associated data field and must not be freed by the application. Applications that need long-term access to this field need to copy the content. .PP \&\fBSSL_CTX_dane_set_flags()\fR and \fBSSL_dane_set_flags()\fR can be used to enable optional \s-1DANE\s0 verification features. \&\fBSSL_CTX_dane_clear_flags()\fR and \fBSSL_dane_clear_flags()\fR can be used to disable the same features. The \fBflags\fR argument is a bit mask of the features to enable or disable. The \fBflags\fR set for an \fB\s-1SSL_CTX\s0\fR context are copied to each \fB\s-1SSL\s0\fR handle associated with that context at the time the handle is created. Subsequent changes in the context's \fBflags\fR have no effect on the \fBflags\fR set for the handle. .PP At present, the only available option is \fB\s-1DANE_FLAG_NO_DANE_EE_NAMECHECKS\s0\fR which can be used to disable server name checks when authenticating via \&\s-1\fBDANE\-EE\s0\fR\|(3) \s-1TLSA\s0 records. For some applications, primarily web browsers, it is not safe to disable name checks due to \*(L"unknown key share\*(R" attacks, in which a malicious server can convince a client that a connection to a victim server is instead a secure connection to the malicious server. The malicious server may then be able to violate cross-origin scripting restrictions. Thus, despite the text of \s-1RFC7671,\s0 name checks are by default enabled for \&\s-1\fBDANE\-EE\s0\fR\|(3) \s-1TLSA\s0 records, and can be disabled in applications where it is safe to do so. In particular, \s-1SMTP\s0 and \s-1XMPP\s0 clients should set this option as \s-1SRV\s0 and \s-1MX\s0 records already make it possible for a remote domain to redirect client connections to any server of its choice, and in any case \s-1SMTP\s0 and \s-1XMPP\s0 clients do not execute scripts downloaded from remote servers. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The functions \fBSSL_CTX_dane_enable()\fR, \fBSSL_CTX_dane_mtype_set()\fR, \&\fBSSL_dane_enable()\fR and \fBSSL_dane_tlsa_add()\fR return a positive value on success. Negative return values indicate resource problems (out of memory, etc.) in the \&\s-1SSL\s0 library, while a return value of \fB0\fR indicates incorrect usage or invalid input, such as an unsupported \s-1TLSA\s0 record certificate usage, selector or matching type. Invalid input also includes malformed data, either a digest length that does not match the digest algorithm, or a \f(CWFull(0)\fR (binary \s-1ASN.1 DER\s0 form) certificate or a public key that fails to parse. .PP The functions \fBSSL_get0_dane_authority()\fR and \fBSSL_get0_dane_tlsa()\fR return a negative value when \s-1DANE\s0 authentication failed or was not enabled, a nonnegative value indicates the chain depth at which the \s-1TLSA\s0 record matched a chain certificate, or the depth of the top-most certificate, when the \s-1TLSA\s0 record is a full public key that is its signer. .PP The functions \fBSSL_CTX_dane_set_flags()\fR, \fBSSL_CTX_dane_clear_flags()\fR, \&\fBSSL_dane_set_flags()\fR and \fBSSL_dane_clear_flags()\fR return the \fBflags\fR in effect before they were called. .SH "EXAMPLES" .IX Header "EXAMPLES" Suppose \*(L"smtp.example.com\*(R" is the \s-1MX\s0 host of the domain \*(L"example.com\*(R", and has DNSSEC-validated \s-1TLSA\s0 records.

Data read from a buffering \s-1BIO\s0 comes from an internal buffer which is filled from the next \s-1BIO\s0 in the chain. Both \fBBIO_gets()\fR and \fBBIO_puts()\fR are supported. .PP Calling \fBBIO_reset()\fR on a buffering \s-1BIO\s0 clears any buffered data. .PP \&\fBBIO_get_buffer_num_lines()\fR returns the number of lines currently buffered. .PP \&\fBBIO_set_read_buffer_size()\fR, \fBBIO_set_write_buffer_size()\fR and \fBBIO_set_buffer_size()\fR set the read, write or both read and write buffer sizes to \fBsize\fR. The initial buffer size is \s-1DEFAULT_BUFFER_SIZE,\s0 currently 4096. Any attempt to reduce the buffer size below \s-1DEFAULT_BUFFER_SIZE\s0 is ignored. Any buffered data is cleared when the buffer is resized. .PP \&\fBBIO_set_buffer_read_data()\fR clears the read buffer and fills it with \fBnum\fR bytes of \fBbuf\fR. If \fBnum\fR is larger than the current buffer size the buffer is expanded. .SH "NOTES" .IX Header "NOTES" These functions, other than \fBBIO_f_buffer()\fR, are implemented as macros. .PP Buffering BIOs implement \fBBIO_read_ex()\fR and \fBBIO_gets()\fR by using \&\fBBIO_read_ex()\fR operations on the next \s-1BIO\s0 in the chain and storing the result in an internal buffer, from which bytes are given back to the caller as appropriate for the call; a \fBBIO_gets()\fR is guaranteed to give the caller a whole line, and \fBBIO_read_ex()\fR is guaranteed to give the caller the number of bytes it asks for, unless there's an error or end of communication is reached in the next \s-1BIO.\s0 By prepending a buffering \s-1BIO\s0 to a chain it is therefore possible to provide \&\fBBIO_gets()\fR or exact size \fBBIO_read_ex()\fR functionality if the following BIOs do not support it. .PP Do not add more than one \fBBIO_f_buffer()\fR to a \s-1BIO\s0 chain. The result of doing so will force a full read of the size of the internal buffer of the top \fBBIO_f_buffer()\fR, which is 4 KiB at a minimum. .PP Data is only written to the next \s-1BIO\s0 in the chain when the write buffer fills or when \fBBIO_flush()\fR is called. It is therefore important to call \fBBIO_flush()\fR whenever any pending data should be written such as when removing a buffering \&\s-1BIO\s0 using \fBBIO_pop()\fR. \fBBIO_flush()\fR may need to be retried if the ultimate source/sink \s-1BIO\s0 is non blocking. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_f_buffer()\fR returns the buffering \s-1BIO\s0 method. .PP \&\fBBIO_get_buffer_num_lines()\fR returns the number of lines buffered (may be 0). .PP \&\fBBIO_set_read_buffer_size()\fR, \fBBIO_set_write_buffer_size()\fR and \fBBIO_set_buffer_size()\fR return 1 if the buffer was successfully resized or 0 for failure. .PP \&\fBBIO_set_buffer_read_data()\fR returns 1 if the data was set correctly or 0 if there was an error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBbio\fR\|(7), \&\fBBIO_reset\fR\|(3), \&\fBBIO_flush\fR\|(3), \&\fBBIO_pop\fR\|(3), \&\fBBIO_ctrl\fR\|(3). .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

It uses a variable size key, but typically, 128 bit (16 byte) keys are considered good for strong encryption. Blowfish can be used in the same modes as \s-1DES\s0 (see \fBdes_modes\fR\|(7)). Blowfish is currently one of the faster block ciphers. It is quite a bit faster than \s-1DES,\s0 and much faster than \s-1IDEA\s0 or \s-1RC2.\s0 .PP Blowfish consists of a key setup phase and the actual encryption or decryption phase. .PP \&\fBBF_set_key()\fR sets up the \fB\s-1BF_KEY\s0\fR \fBkey\fR using the \fBlen\fR bytes long key at \fBdata\fR. .PP \&\fBBF_ecb_encrypt()\fR is the basic Blowfish encryption and decryption function. It encrypts or decrypts the first 64 bits of \fBin\fR using the key \fBkey\fR, putting the result in \fBout\fR. \fBenc\fR decides if encryption (\fB\s-1BF_ENCRYPT\s0\fR) or decryption (\fB\s-1BF_DECRYPT\s0\fR) shall be performed. The vector pointed at by \&\fBin\fR and \fBout\fR must be 64 bits in length, no less. If they are larger, everything after the first 64 bits is ignored. .PP The mode functions \fBBF_cbc_encrypt()\fR, \fBBF_cfb64_encrypt()\fR and \fBBF_ofb64_encrypt()\fR all operate on variable length data. They all take an initialization vector \&\fBivec\fR which needs to be passed along into the next call of the same function for the same message. \fBivec\fR may be initialized with anything, but the recipient needs to know what it was initialized with, or it won't be able to decrypt. Some programs and protocols simplify this, like \s-1SSH,\s0 where \&\fBivec\fR is simply initialized to zero. \&\fBBF_cbc_encrypt()\fR operates on data that is a multiple of 8 bytes long, while \&\fBBF_cfb64_encrypt()\fR and \fBBF_ofb64_encrypt()\fR are used to encrypt a variable number of bytes (the amount does not have to be an exact multiple of 8). The purpose of the latter two is to simulate stream ciphers, and therefore, they need the parameter \fBnum\fR, which is a pointer to an integer where the current offset in \fBivec\fR is stored between calls. This integer must be initialized to zero when \fBivec\fR is initialized. .PP \&\fBBF_cbc_encrypt()\fR is the Cipher Block Chaining function for Blowfish. It encrypts or decrypts the 64 bits chunks of \fBin\fR using the key \fBschedule\fR, putting the result in \fBout\fR. \fBenc\fR decides if encryption (\s-1BF_ENCRYPT\s0) or decryption (\s-1BF_DECRYPT\s0) shall be performed. \fBivec\fR must point at an 8 byte long initialization vector. .PP \&\fBBF_cfb64_encrypt()\fR is the \s-1CFB\s0 mode for Blowfish with 64 bit feedback. It encrypts or decrypts the bytes in \fBin\fR using the key \fBschedule\fR, putting the result in \fBout\fR. \fBenc\fR decides if encryption (\fB\s-1BF_ENCRYPT\s0\fR) or decryption (\fB\s-1BF_DECRYPT\s0\fR) shall be performed. \fBivec\fR must point at an 8 byte long initialization vector. \fBnum\fR must point at an integer which must be initially zero. .PP \&\fBBF_ofb64_encrypt()\fR is the \s-1OFB\s0 mode for Blowfish with 64 bit feedback. It uses the same parameters as \fBBF_cfb64_encrypt()\fR, which must be initialized the same way. .PP \&\fBBF_encrypt()\fR and \fBBF_decrypt()\fR are the lowest level functions for Blowfish encryption. They encrypt/decrypt the first 64 bits of the vector pointed by \&\fBdata\fR, using the key \fBkey\fR. These functions should not be used unless you implement 'modes' of Blowfish. The alternative is to use \fBBF_ecb_encrypt()\fR. If you still want to use these functions, you should be aware that they take each 32\-bit chunk in host-byte order, which is little-endian on little-endian platforms and big-endian on big-endian ones. .SH "RETURN VALUES" .IX Header "RETURN VALUES" None of the functions presented here return any value. .SH "NOTE" .IX Header "NOTE" Applications should use the higher level functions \&\fBEVP_EncryptInit\fR\|(3) etc. instead of calling these functions directly. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_EncryptInit\fR\|(3), \&\fBdes_modes\fR\|(7) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

The argument supplied when setting the callback is passed back to the callback at runtime. A callback that returns failure (0) will cause the connection to terminate, and callbacks returning failure should indicate what alert value is to be sent in the \fBal\fR parameter. A callback may also return a negative value to suspend the handshake, and the handshake function will return immediately. \fBSSL_get_error\fR\|(3) will return \&\s-1SSL_ERROR_WANT_CLIENT_HELLO_CB\s0 to indicate that the handshake was suspended. It is the job of the ClientHello callback to store information about the state of the last call if needed to continue. On the next call into the handshake function, the ClientHello callback will be called again, and, if it returns success, normal handshake processing will continue from that point. .PP \&\fBSSL_client_hello_isv2()\fR indicates whether the ClientHello was carried in a SSLv2 record and is in the SSLv2 format. The SSLv2 format has substantial differences from the normal SSLv3 format, including using three bytes per cipher suite, and not allowing extensions. Additionally, the SSLv2 format \&'challenge' field is exposed via \fBSSL_client_hello_get0_random()\fR, padded to \&\s-1SSL3_RANDOM_SIZE\s0 bytes with zeros if needed. For SSLv2 format ClientHellos, \&\fBSSL_client_hello_get0_compression_methods()\fR returns a dummy list that only includes the null compression method, since the SSLv2 format does not include a mechanism by which to negotiate compression. .PP \&\fBSSL_client_hello_get0_random()\fR, \fBSSL_client_hello_get0_session_id()\fR, \&\fBSSL_client_hello_get0_ciphers()\fR, and \&\fBSSL_client_hello_get0_compression_methods()\fR provide access to the corresponding ClientHello fields, returning the field length and optionally setting an out pointer to the octets of that field. .PP Similarly, \fBSSL_client_hello_get0_ext()\fR provides access to individual extensions from the ClientHello on a per-extension basis. For the provided wire protocol extension type value, the extension value and length are returned in the output parameters (if present). .PP \&\fBSSL_client_hello_get1_extensions_present()\fR can be used prior to \&\fBSSL_client_hello_get0_ext()\fR, to determine which extensions are present in the ClientHello before querying for them. The \fBout\fR and \fBoutlen\fR parameters are both required, and on success the caller must release the storage allocated for \&\fB*out\fR using \fBOPENSSL_free()\fR. The contents of \fB*out\fR is an array of integers holding the numerical value of the \s-1TLS\s0 extension types in the order they appear in the ClientHello. \fB*outlen\fR contains the number of elements in the array. In situations when the ClientHello has no extensions, the function will return success with \fB*out\fR set to \s-1NULL\s0 and \fB*outlen\fR set to 0. .SH "NOTES" .IX Header "NOTES" The ClientHello callback provides a vast window of possibilities for application code to affect the \s-1TLS\s0 handshake. A primary use of the callback is to allow the server to examine the server name indication extension provided by the client in order to select an appropriate certificate to present, and make other configuration adjustments relevant to that server name and its configuration. Such configuration changes can include swapping out the associated \s-1SSL_CTX\s0 pointer, modifying the server's list of permitted \s-1TLS\s0 versions, changing the server's cipher list in response to the client's cipher list, etc. .PP It is also recommended that applications utilize a ClientHello callback and not use a servername callback, in order to avoid unexpected behavior that occurs due to the relative order of processing between things like session resumption and the historical servername callback. .PP The SSL_client_hello_* family of functions may only be called from code executing within a ClientHello callback. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The application's supplied ClientHello callback returns \&\s-1SSL_CLIENT_HELLO_SUCCESS\s0 on success, \s-1SSL_CLIENT_HELLO_ERROR\s0 on failure, and \&\s-1SSL_CLIENT_HELLO_RETRY\s0 to suspend processing. .PP \&\fBSSL_client_hello_isv2()\fR returns 1 for SSLv2\-format ClientHellos and 0 otherwise. .PP \&\fBSSL_client_hello_get0_random()\fR, \fBSSL_client_hello_get0_session_id()\fR, \&\fBSSL_client_hello_get0_ciphers()\fR, and \&\fBSSL_client_hello_get0_compression_methods()\fR return the length of the corresponding ClientHello fields. If zero is returned, the output pointer should not be assumed to be valid. .PP \&\fBSSL_client_hello_get0_ext()\fR returns 1 if the extension of type 'type' is present, and 0 otherwise. .PP \&\fBSSL_client_hello_get1_extensions_present()\fR returns 1 on success and 0 on failure. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_CTX_set_tlsext_servername_callback\fR\|(3), SSL_bytes_to_cipher_list .SH "HISTORY" .IX Header "HISTORY" The \s-1SSL\s0 ClientHello callback, \fBSSL_client_hello_isv2()\fR, \&\fBSSL_client_hello_get0_random()\fR, \fBSSL_client_hello_get0_session_id()\fR, \&\fBSSL_client_hello_get0_ciphers()\fR, \fBSSL_client_hello_get0_compression_methods()\fR, \&\fBSSL_client_hello_get0_ext()\fR, and \fBSSL_client_hello_get1_extensions_present()\fR were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2017\-2019 The OpenSSL Project Authors.

They generate a random key and \s-1IV\s0 (if required) then \&\*(L"envelope\*(R" it by using public key encryption. Data can then be encrypted using this key. .PP \&\fBEVP_SealInit()\fR initializes a cipher context \fBctx\fR for encryption with cipher \fBtype\fR using a random secret key and \s-1IV.\s0 \fBtype\fR is normally supplied by a function such as \fBEVP_aes_256_cbc()\fR. The secret key is encrypted using one or more public keys, this allows the same encrypted data to be decrypted using any of the corresponding private keys. \fBek\fR is an array of buffers where the public key encrypted secret key will be written, each buffer must contain enough room for the corresponding encrypted key: that is \&\fBek[i]\fR must have room for \fBEVP_PKEY_size(pubk[i])\fR bytes. The actual size of each encrypted secret key is written to the array \fBekl\fR. \fBpubk\fR is an array of \fBnpubk\fR public keys. .PP The \fBiv\fR parameter is a buffer where the generated \s-1IV\s0 is written to. It must contain enough room for the corresponding cipher's \s-1IV,\s0 as determined by (for example) EVP_CIPHER_iv_length(type). .PP If the cipher does not require an \s-1IV\s0 then the \fBiv\fR parameter is ignored and can be \fB\s-1NULL\s0\fR. .PP \&\fBEVP_SealUpdate()\fR and \fBEVP_SealFinal()\fR have exactly the same properties as the \fBEVP_EncryptUpdate()\fR and \fBEVP_EncryptFinal()\fR routines, as documented on the \fBEVP_EncryptInit\fR\|(3) manual page. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_SealInit()\fR returns 0 on error or \fBnpubk\fR if successful. .PP \&\fBEVP_SealUpdate()\fR and \fBEVP_SealFinal()\fR return 1 for success and 0 for failure. .SH "NOTES" .IX Header "NOTES" Because a random secret key is generated the random number generator must be seeded when \fBEVP_SealInit()\fR is called. If the automatic seeding or reseeding of the OpenSSL \s-1CSPRNG\s0 fails due to external circumstances (see \s-1\fBRAND\s0\fR\|(7)), the operation will fail. .PP The public key must be \s-1RSA\s0 because it is the only OpenSSL public key algorithm that supports key transport. .PP Envelope encryption is the usual method of using public key encryption on large amounts of data, this is because public key encryption is slow but symmetric encryption is fast. So symmetric encryption is used for bulk encryption and the small random symmetric key used is transferred using public key encryption. .PP It is possible to call \fBEVP_SealInit()\fR twice in the same way as \&\fBEVP_EncryptInit()\fR. The first call should have \fBnpubk\fR set to 0 and (after setting any cipher parameters) it should be called again with \fBtype\fR set to \s-1NULL.\s0 .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBevp\fR\|(7), \fBRAND_bytes\fR\|(3), \&\fBEVP_EncryptInit\fR\|(3), \&\fBEVP_OpenInit\fR\|(3), \&\s-1\fBRAND\s0\fR\|(7) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

It is recommended that \fBadd\fR is a multiple of 4. .PP The random generator must be seeded prior to calling \fBBN_generate_prime_ex()\fR.

If \&\fBnchecks == BN_prime_checks\fR, a number of iterations is used that yields a false positive rate of at most 2^\-64 for random input. The error rate depends on the size of the prime and goes down for bigger primes. The rate is 2^\-80 starting at 308 bits, 2^\-112 at 852 bits, 2^\-128 at 1080 bits, 2^\-192 at 3747 bits and 2^\-256 at 6394 bits. .PP When the source of the prime is not random or not trusted, the number of checks needs to be much higher to reach the same level of assurance: It should equal half of the targeted security level in bits (rounded up to the next integer if necessary). For instance, to reach the 128 bit security level, \fBnchecks\fR should be set to 64. .PP If \fBcb\fR is not \fB\s-1NULL\s0\fR, \fBBN_GENCB_call(cb, 1, j)\fR is called after the j\-th iteration (j = 0, 1, ...). \fBctx\fR is a preallocated \fB\s-1BN_CTX\s0\fR (to save the overhead of allocating and freeing the structure in a loop), or \fB\s-1NULL\s0\fR. .PP \&\fBBN_GENCB_call()\fR calls the callback function held in the \fB\s-1BN_GENCB\s0\fR structure and passes the ints \fBa\fR and \fBb\fR as arguments. There are two types of \&\fB\s-1BN_GENCB\s0\fR structure that are supported: \*(L"new\*(R" style and \*(L"old\*(R" style. New programs should prefer the \*(L"new\*(R" style, whilst the \*(L"old\*(R" style is provided for backwards compatibility purposes. .PP A \fB\s-1BN_GENCB\s0\fR structure should be created through a call to \fBBN_GENCB_new()\fR, and freed through a call to \fBBN_GENCB_free()\fR. .PP For \*(L"new\*(R" style callbacks a \s-1BN_GENCB\s0 structure should be initialised with a call to \fBBN_GENCB_set()\fR, where \fBgencb\fR is a \fB\s-1BN_GENCB\s0 *\fR, \fBcallback\fR is of type \fBint (*callback)(int, int, \s-1BN_GENCB\s0 *)\fR and \fBcb_arg\fR is a \fBvoid *\fR. \&\*(L"Old\*(R" style callbacks are the same except they are initialised with a call to \fBBN_GENCB_set_old()\fR and \fBcallback\fR is of type \&\fBvoid (*callback)(int, int, void *)\fR. .PP A callback is invoked through a call to \fBBN_GENCB_call\fR. This will check the type of the callback and will invoke \fBcallback(a, b, gencb)\fR for new style callbacks or \fBcallback(a, b, cb_arg)\fR for old style. .PP It is possible to obtain the argument associated with a \s-1BN_GENCB\s0 structure (set via a call to BN_GENCB_set or BN_GENCB_set_old) using BN_GENCB_get_arg. .PP \&\fBBN_generate_prime()\fR (deprecated) works in the same way as \&\fBBN_generate_prime_ex()\fR but expects an old-style callback function directly in the \fBcallback\fR parameter, and an argument to pass to it in the \fBcb_arg\fR. \fBBN_is_prime()\fR and \fBBN_is_prime_fasttest()\fR can similarly be compared to \fBBN_is_prime_ex()\fR and \&\fBBN_is_prime_fasttest_ex()\fR, respectively. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBN_generate_prime_ex()\fR return 1 on success or 0 on error. .PP \&\fBBN_is_prime_ex()\fR, \fBBN_is_prime_fasttest_ex()\fR, \fBBN_is_prime()\fR and \&\fBBN_is_prime_fasttest()\fR return 0 if the number is composite, 1 if it is prime with an error probability of less than 0.25^\fBnchecks\fR, and \&\-1 on error. .PP \&\fBBN_generate_prime()\fR returns the prime number on success, \fB\s-1NULL\s0\fR otherwise. .PP BN_GENCB_new returns a pointer to a \s-1BN_GENCB\s0 structure on success, or \fB\s-1NULL\s0\fR otherwise. .PP BN_GENCB_get_arg returns the argument previously associated with a \s-1BN_GENCB\s0 structure. .PP Callback functions should return 1 on success or 0 on error. .PP The error codes can be obtained by \fBERR_get_error\fR\|(3). .SH "REMOVED FUNCTIONALITY" .IX Header "REMOVED FUNCTIONALITY" As of OpenSSL 1.1.0 it is no longer possible to create a \s-1BN_GENCB\s0 structure directly, as in: .PP .Vb 1 \& BN_GENCB callback; .Ve .PP Instead applications should create a \s-1BN_GENCB\s0 structure using BN_GENCB_new: .PP .Vb 6 \& BN_GENCB *callback; \& callback = BN_GENCB_new(); \& if (!callback) \& /* error */ \& ... \& BN_GENCB_free(callback); .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBDH_generate_parameters\fR\|(3), \fBDSA_generate_parameters\fR\|(3), \&\fBRSA_generate_key\fR\|(3), \fBERR_get_error\fR\|(3), \fBRAND_bytes\fR\|(3), \&\s-1\fBRAND\s0\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" The \fBBN_GENCB_new()\fR, \fBBN_GENCB_free()\fR, and \fBBN_GENCB_get_arg()\fR functions were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

Using a \fB\s-1NULL\s0\fR pointer for \fIcb\fR disables the message callback. .PP When \fIcb\fR is called by the \s-1SSL/TLS\s0 library the function arguments have the following meaning: .IP "\fIwrite_p\fR" 4 .IX Item "write_p" This flag is \fB0\fR when a protocol message has been received and \fB1\fR when a protocol message has been sent. .IP "\fIversion\fR" 4 .IX Item "version" The protocol version according to which the protocol message is interpreted by the library such as \fB\s-1TLS1_3_VERSION\s0\fR, \fB\s-1TLS1_2_VERSION\s0\fR etc. This is set to 0 for the \s-1SSL3_RT_HEADER\s0 pseudo content type (see \s-1NOTES\s0 below). .IP "\fIcontent_type\fR" 4 .IX Item "content_type" This is one of the content type values defined in the protocol specification (\fB\s-1SSL3_RT_CHANGE_CIPHER_SPEC\s0\fR, \fB\s-1SSL3_RT_ALERT\s0\fR, \fB\s-1SSL3_RT_HANDSHAKE\s0\fR; but never \&\fB\s-1SSL3_RT_APPLICATION_DATA\s0\fR because the callback will only be called for protocol messages). Alternatively it may be a \*(L"pseudo\*(R" content type. These pseudo content types are used to signal some other event in the processing of data (see \&\s-1NOTES\s0 below). .IP "\fIbuf\fR, \fIlen\fR" 4 .IX Item "buf, len" \&\fIbuf\fR points to a buffer containing the protocol message or other data (in the case of pseudo content types), which consists of \fIlen\fR bytes.

(Thus record boundaries are not visible.) .PP If processing a received protocol message results in an error, the callback function may not be called. For example, the callback function will never see messages that are considered too large to be processed. .PP Due to automatic protocol version negotiation, \fIversion\fR is not necessarily the protocol version used by the sender of the message: If a \s-1TLS 1.0\s0 ClientHello message is received by an \s-1SSL 3\s0.0\-only server, \&\fIversion\fR will be \fB\s-1SSL3_VERSION\s0\fR. .PP Pseudo content type values may be sent at various points during the processing of data. The following pseudo content types are currently defined: .IP "\fB\s-1SSL3_RT_HEADER\s0\fR" 4 .IX Item "SSL3_RT_HEADER" Used when a record is sent or received. The \fBbuf\fR contains the record header bytes only. .IP "\fB\s-1SSL3_RT_INNER_CONTENT_TYPE\s0\fR" 4 .IX Item "SSL3_RT_INNER_CONTENT_TYPE" Used when an encrypted TLSv1.3 record is sent or received.

Additional application data can be passed to the callback via the \fBex_data\fR mechanism. .PP \&\fBX509_STORE_CTX_get_verify_cb()\fR returns the value of the current callback for the specific \fBctx\fR. .PP \&\fBX509_STORE_CTX_get_get_issuer()\fR, \&\fBX509_STORE_CTX_get_check_issued()\fR, \fBX509_STORE_CTX_get_check_revocation()\fR, \&\fBX509_STORE_CTX_get_get_crl()\fR, \fBX509_STORE_CTX_get_check_crl()\fR, \&\fBX509_STORE_CTX_get_cert_crl()\fR, \fBX509_STORE_CTX_get_check_policy()\fR, \&\fBX509_STORE_CTX_get_lookup_certs()\fR, \fBX509_STORE_CTX_get_lookup_crls()\fR and \fBX509_STORE_CTX_get_cleanup()\fR return the function pointers cached from the corresponding \fBX509_STORE\fR, please see \&\fBX509_STORE_set_verify\fR\|(3) for more information. .SH "WARNINGS" .IX Header "WARNINGS" In general a verification callback should \fB\s-1NOT\s0\fR unconditionally return 1 in all circumstances because this will allow verification to succeed no matter what the error. This effectively removes all security from the application because \fBany\fR certificate (including untrusted generated ones) will be accepted. .SH "NOTES" .IX Header "NOTES" The verification callback can be set and inherited from the parent structure performing the operation. In some cases (such as S/MIME verification) the \&\fBX509_STORE_CTX\fR structure is created and destroyed internally and the only way to set a custom verification callback is by inheriting it from the associated \fBX509_STORE\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBX509_STORE_CTX_set_verify_cb()\fR does not return a value. .SH "EXAMPLES" .IX Header "EXAMPLES" Default callback operation: .PP .Vb 3 \& int verify_callback(int ok, X509_STORE_CTX *ctx) { \& return ok; \& } .Ve .PP Simple example, suppose a certificate in the chain is expired and we wish to continue after this error: .PP .Vb 7 \& int verify_callback(int ok, X509_STORE_CTX *ctx) { \& /* Tolerate certificate expiration */ \& if (X509_STORE_CTX_get_error(ctx) == X509_V_ERR_CERT_HAS_EXPIRED) \& return 1; \& /* Otherwise don\*(Aqt override */ \& return ok; \& } .Ve .PP More complex example, we don't wish to continue after \fBany\fR certificate has expired just one specific case: .PP .Vb 4 \& int verify_callback(int ok, X509_STORE_CTX *ctx) \& { \& int err = X509_STORE_CTX_get_error(ctx); \& X509 *err_cert = X509_STORE_CTX_get_current_cert(ctx); \& \& if (err == X509_V_ERR_CERT_HAS_EXPIRED) { \& if (check_is_acceptable_expired_cert(err_cert) \& return 1; \& } \& return ok; \& } .Ve .PP Full featured logging callback.

Similarly EC_POINT_dbl doubles the point \fBa\fR and places the result in \fBr\fR. In both cases it is valid for \fBr\fR to be one of \fBa\fR or \fBb\fR. .PP EC_POINT_invert calculates the inverse of the supplied point \fBa\fR. The result is placed back in \fBa\fR. .PP The function EC_POINT_is_at_infinity tests whether the supplied point is at infinity or not. .PP EC_POINT_is_on_curve tests whether the supplied point is on the curve or not. .PP EC_POINT_cmp compares the two supplied points and tests whether or not they are equal. .PP The functions EC_POINT_make_affine and EC_POINTs_make_affine force the internal representation of the \s-1EC_POINT\s0(s) into the affine co-ordinate system. In the case of EC_POINTs_make_affine the value \fBnum\fR provides the number of points in the array \fBpoints\fR to be forced. .PP EC_POINT_mul is a convenient interface to EC_POINTs_mul: it calculates the value generator * \fBn\fR + \fBq\fR * \fBm\fR and stores the result in \fBr\fR. The value \fBn\fR may be \s-1NULL\s0 in which case the result is just \fBq\fR * \fBm\fR (variable point multiplication). Alternatively, both \fBq\fR and \fBm\fR may be \s-1NULL,\s0 and \fBn\fR non-NULL, in which case the result is just generator * \fBn\fR (fixed point multiplication). When performing a single fixed or variable point multiplication, the underlying implementation uses a constant time algorithm, when the input scalar (either \fBn\fR or \fBm\fR) is in the range [0, ec_group_order). .PP EC_POINTs_mul calculates the value generator * \fBn\fR + \fBq[0]\fR * \fBm[0]\fR + ... + \fBq[num\-1]\fR * \fBm[num\-1]\fR. As for EC_POINT_mul the value \fBn\fR may be \s-1NULL\s0 or \fBnum\fR may be zero. When performing a fixed point multiplication (\fBn\fR is non-NULL and \fBnum\fR is 0) or a variable point multiplication (\fBn\fR is \s-1NULL\s0 and \fBnum\fR is 1), the underlying implementation uses a constant time algorithm, when the input scalar (either \fBn\fR or \fBm[0]\fR) is in the range [0, ec_group_order). .PP The function EC_GROUP_precompute_mult stores multiples of the generator for faster point multiplication, whilst EC_GROUP_have_precompute_mult tests whether precomputation has already been done. See \fBEC_GROUP_copy\fR\|(3) for information about the generator. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following functions return 1 on success or 0 on error: EC_POINT_add, EC_POINT_dbl, EC_POINT_invert, EC_POINT_make_affine, EC_POINTs_make_affine, EC_POINTs_make_affine, EC_POINT_mul, EC_POINTs_mul and EC_GROUP_precompute_mult. .PP EC_POINT_is_at_infinity returns 1 if the point is at infinity, or 0 otherwise. .PP EC_POINT_is_on_curve returns 1 if the point is on the curve, 0 if not, or \-1 on error. .PP EC_POINT_cmp returns 1 if the points are not equal, 0 if they are, or \-1 on error. .PP EC_GROUP_have_precompute_mult return 1 if a precomputation has been done, or 0 if not. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBcrypto\fR\|(7), \fBEC_GROUP_new\fR\|(3), \fBEC_GROUP_copy\fR\|(3), \&\fBEC_POINT_new\fR\|(3), \fBEC_KEY_new\fR\|(3), \&\fBEC_GFp_simple_method\fR\|(3), \fBd2i_ECPKParameters\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2013\-2018 The OpenSSL Project Authors.

It copies as many bytes as it can of this value into the buffer provided in \fBout\fR, which must have at least \fBoutlen\fR bytes available. It returns the total number of bytes that were actually copied. If \fBoutlen\fR is zero, \fBSSL_get_client_random()\fR copies nothing, and returns the total size of the client_random value. .PP \&\fBSSL_get_server_random()\fR behaves the same, but extracts the random value sent from the server to the client during the initial \s-1SSL/TLS\s0 handshake. .PP \&\fBSSL_SESSION_get_master_key()\fR behaves the same, but extracts the master secret used to guarantee the security of the \s-1SSL/TLS\s0 session. This one can be dangerous if misused; see \s-1NOTES\s0 below. .PP \&\fBSSL_SESSION_set1_master_key()\fR sets the master key value associated with the \&\s-1SSL_SESSION\s0 \fBsess\fR. For example, this could be used to set up a session based \&\s-1PSK\s0 (see \fBSSL_CTX_set_psk_use_session_callback\fR\|(3)). The master key of length \&\fBlen\fR should be provided at \fBin\fR. The supplied master key is copied by the function, so the caller is responsible for freeing and cleaning any memory associated with \fBin\fR. The caller must ensure that the length of the key is suitable for the ciphersuite associated with the \s-1SSL_SESSION.\s0 .SH "NOTES" .IX Header "NOTES" You probably shouldn't use these functions. .PP These functions expose internal values from the \s-1TLS\s0 handshake, for use in low-level protocols. You probably should not use them, unless you are implementing something that needs access to the internal protocol details. .PP Despite the names of \fBSSL_get_client_random()\fR and \fBSSL_get_server_random()\fR, they \&\s-1ARE NOT\s0 random number generators. Instead, they return the mostly-random values that were already generated and used in the \s-1TLS\s0 protocol. Using them in place of \fBRAND_bytes()\fR would be grossly foolish. .PP The security of your \s-1TLS\s0 session depends on keeping the master key secret: do not expose it, or any information about it, to anybody. If you need to calculate another secret value that depends on the master secret, you should probably use \fBSSL_export_keying_material()\fR instead, and forget that you ever saw these functions. .PP In current versions of the \s-1TLS\s0 protocols, the length of client_random (and also server_random) is always \s-1SSL3_RANDOM_SIZE\s0 bytes. Support for other outlen arguments to the SSL_get_*\fB_random()\fR functions is provided in case of the unlikely event that a future version or variant of \s-1TLS\s0 uses some other length there. .PP Finally, though the \*(L"client_random\*(R" and \*(L"server_random\*(R" values are called \&\*(L"random\*(R", many \s-1TLS\s0 implementations will generate four bytes of those values based on their view of the current time. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_SESSION_set1_master_key()\fR returns 1 on success or 0 on failure. .PP For the other functions, if \fBoutlen\fR is greater than 0 then these functions return the number of bytes actually copied, which will be less than or equal to \&\fBoutlen\fR.

There are three modes that are currently defined: .IP "\s-1EVP_PKEY_HKDEF_MODE_EXTRACT_AND_EXPAND\s0" 4 .IX Item "EVP_PKEY_HKDEF_MODE_EXTRACT_AND_EXPAND" This is the default mode.

The intermediate fixed-length pseudorandom key K is not returned. .Sp In this mode the digest, key, salt and info values must be set before a key is derived or an error occurs. .IP "\s-1EVP_PKEY_HKDEF_MODE_EXTRACT_ONLY\s0" 4 .IX Item "EVP_PKEY_HKDEF_MODE_EXTRACT_ONLY" In this mode calling \fBEVP_PKEY_derive\fR\|(3) will just perform the extract operation.

The \fBtype\fR parameter \*(L"md\*(R" uses the supplied \fBvalue\fR as the name of the digest algorithm to use. The \fBtype\fR parameter \*(L"mode\*(R" uses the values \*(L"\s-1EXTRACT_AND_EXPAND\*(R", \&\*(L"EXTRACT_ONLY\*(R"\s0 and \*(L"\s-1EXPAND_ONLY\*(R"\s0 to determine the mode to use. The \fBtype\fR parameters \*(L"salt\*(R", \*(L"key\*(R" and \*(L"info\*(R" use the supplied \fBvalue\fR parameter as a \fBseed\fR, \fBkey\fR or \fBinfo\fR value. The names \*(L"hexsalt\*(R", \*(L"hexkey\*(R" and \*(L"hexinfo\*(R" are similar except they take a hex string which is converted to binary. .SH "NOTES" .IX Header "NOTES" All these functions are implemented as macros. .PP A context for \s-1HKDF\s0 can be obtained by calling: .PP .Vb 1 \& EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_HKDF, NULL); .Ve .PP The total length of the info buffer cannot exceed 1024 bytes in length: this should be more than enough for any normal use of \s-1HKDF.\s0 .PP The output length of an \s-1HKDF\s0 expand operation is specified via the length parameter to the \fBEVP_PKEY_derive\fR\|(3) function. Since the \s-1HKDF\s0 output length is variable, passing a \fB\s-1NULL\s0\fR buffer as a means to obtain the requisite length is not meaningful with \s-1HKDF\s0 in any mode that performs an expand operation. Instead, the caller must allocate a buffer of the desired length, and pass that buffer to \fBEVP_PKEY_derive\fR\|(3) along with (a pointer initialized to) the desired length. Passing a \fB\s-1NULL\s0\fR buffer to obtain the length is allowed when using \s-1EVP_PKEY_HKDEF_MODE_EXTRACT_ONLY.\s0 .PP Optimised versions of \s-1HKDF\s0 can be implemented in an \s-1ENGINE.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" All these functions return 1 for success and 0 or a negative value for failure.

The field value to be added is in \fBbytes\fR of length \fBlen\fR. If \&\fBlen\fR is \-1 then the field length is calculated internally using strlen(bytes). .PP The type of field is determined by \fBtype\fR which can either be a definition of the type of \fBbytes\fR (such as \fB\s-1MBSTRING_ASC\s0\fR) or a standard \s-1ASN1\s0 type (such as \fBV_ASN1_IA5STRING\fR). The new entry is added to a position determined by \fBloc\fR and \fBset\fR. .PP \&\fBX509_NAME_add_entry()\fR adds a copy of \fBX509_NAME_ENTRY\fR structure \fBne\fR to \fBname\fR. The new entry is added to a position determined by \fBloc\fR and \fBset\fR. Since a copy of \fBne\fR is added \fBne\fR must be freed up after the call. .PP \&\fBX509_NAME_delete_entry()\fR deletes an entry from \fBname\fR at position \&\fBloc\fR. The deleted entry is returned and must be freed up. .SH "NOTES" .IX Header "NOTES" The use of string types such as \fB\s-1MBSTRING_ASC\s0\fR or \fB\s-1MBSTRING_UTF8\s0\fR is strongly recommended for the \fBtype\fR parameter. This allows the internal code to correctly determine the type of the field and to apply length checks according to the relevant standards. This is done using \fBASN1_STRING_set_by_NID()\fR. .PP If instead an \s-1ASN1\s0 type is used no checks are performed and the supplied data in \fBbytes\fR is used directly. .PP In \fBX509_NAME_add_entry_by_txt()\fR the \fBfield\fR string represents the field name using OBJ_txt2obj(field, 0). .PP The \fBloc\fR and \fBset\fR parameters determine where a new entry should be added. For almost all applications \fBloc\fR can be set to \-1 and \fBset\fR to 0. This adds a new entry to the end of \fBname\fR as a single valued RelativeDistinguishedName (\s-1RDN\s0). .PP \&\fBloc\fR actually determines the index where the new entry is inserted: if it is \-1 it is appended. .PP \&\fBset\fR determines how the new type is added. If it is zero a new \s-1RDN\s0 is created. .PP If \fBset\fR is \-1 or 1 it is added to the previous or next \s-1RDN\s0 structure respectively. This will then be a multivalued \s-1RDN:\s0 since multivalues RDNs are very seldom used \fBset\fR is almost always set to zero. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBX509_NAME_add_entry_by_txt()\fR, \fBX509_NAME_add_entry_by_OBJ()\fR, \&\fBX509_NAME_add_entry_by_NID()\fR and \fBX509_NAME_add_entry()\fR return 1 for success of 0 if an error occurred. .PP \&\fBX509_NAME_delete_entry()\fR returns either the deleted \fBX509_NAME_ENTRY\fR structure of \fB\s-1NULL\s0\fR if an error occurred. .SH "EXAMPLES" .IX Header "EXAMPLES" Create an \fBX509_NAME\fR structure: .PP \&\*(L"C=UK, O=Disorganized Organization, CN=Joe Bloggs\*(R" .PP .Vb 1 \& X509_NAME *nm; \& \& nm = X509_NAME_new(); \& if (nm == NULL) \& /* Some error */ \& if (!X509_NAME_add_entry_by_txt(nm, "C", MBSTRING_ASC, \& "UK", \-1, \-1, 0)) \& /* Error */ \& if (!X509_NAME_add_entry_by_txt(nm, "O", MBSTRING_ASC, \& "Disorganized Organization", \-1, \-1, 0)) \& /* Error */ \& if (!X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, \& "Joe Bloggs", \-1, \-1, 0)) \& /* Error */ .Ve .SH "BUGS" .IX Header "BUGS" \&\fBtype\fR can still be set to \fBV_ASN1_APP_CHOOSE\fR to use a different algorithm to determine field types.

If the flags returned do not provide sufficient information an application should examine extension values directly for example using \fBX509_get_ext_d2i()\fR. .PP If the key usage or extended key usage extension is absent then typically usage is unrestricted. For this reason \fBX509_get_key_usage()\fR and \&\fBX509_get_extended_key_usage()\fR return \fB\s-1UINT32_MAX\s0\fR when the corresponding extension is absent. Applications can additionally check the return value of \&\fBX509_get_extension_flags()\fR and take appropriate action is an extension is absent. .PP If \fBX509_get0_subject_key_id()\fR returns \fB\s-1NULL\s0\fR then the extension may be absent or malformed.

To do so the client should call the \&\fBSSL_CTX_set_tlsext_status_type()\fR function prior to the creation of any \s-1SSL\s0 objects. Alternatively an application can call the \fBSSL_set_tlsext_status_type()\fR function on an individual \s-1SSL\s0 object prior to the start of the handshake. Currently the only supported type is \fBTLSEXT_STATUSTYPE_ocsp\fR. This value should be passed in the \fBtype\fR argument. Calling \&\fBSSL_CTX_get_tlsext_status_type()\fR will return the type \fBTLSEXT_STATUSTYPE_ocsp\fR previously set via \fBSSL_CTX_set_tlsext_status_type()\fR or \-1 if not set. .PP The client should additionally provide a callback function to decide what to do with the returned \s-1OCSP\s0 response by calling \fBSSL_CTX_set_tlsext_status_cb()\fR. The callback function should determine whether the returned \s-1OCSP\s0 response is acceptable or not. The callback will be passed as an argument the value previously set via a call to \fBSSL_CTX_set_tlsext_status_arg()\fR. Note that the callback will not be called in the event of a handshake where session resumption occurs (because there are no Certificates exchanged in such a handshake). The callback previously set via \fBSSL_CTX_set_tlsext_status_cb()\fR can be retrieved by calling \fBSSL_CTX_get_tlsext_status_cb()\fR, and the argument by calling \&\fBSSL_CTX_get_tlsext_status_arg()\fR. .PP On the client side \fBSSL_get_tlsext_status_type()\fR can be used to determine whether the client has previously called \fBSSL_set_tlsext_status_type()\fR. It will return \&\fBTLSEXT_STATUSTYPE_ocsp\fR if it has been called or \-1 otherwise. On the server side \fBSSL_get_tlsext_status_type()\fR can be used to determine whether the client requested \s-1OCSP\s0 stapling. If the client requested it then this function will return \fBTLSEXT_STATUSTYPE_ocsp\fR, or \-1 otherwise. .PP The response returned by the server can be obtained via a call to \&\fBSSL_get_tlsext_status_ocsp_resp()\fR. The value \fB*resp\fR will be updated to point to the \s-1OCSP\s0 response data and the return value will be the length of that data. Typically a callback would obtain an \s-1OCSP_RESPONSE\s0 object from this data via a call to the \fBd2i_OCSP_RESPONSE()\fR function. If the server has not provided any response data then \fB*resp\fR will be \s-1NULL\s0 and the return value from \&\fBSSL_get_tlsext_status_ocsp_resp()\fR will be \-1. .PP A server application must also call the \fBSSL_CTX_set_tlsext_status_cb()\fR function if it wants to be able to provide clients with \s-1OCSP\s0 Certificate Status responses. Typically the server callback would obtain the server certificate that is being sent back to the client via a call to \fBSSL_get_certificate()\fR; obtain the \s-1OCSP\s0 response to be sent back; and then set that response data by calling \fBSSL_set_tlsext_status_ocsp_resp()\fR. A pointer to the response data should be provided in the \fBresp\fR argument, and the length of that data should be in the \fBlen\fR argument. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The callback when used on the client side should return a negative value on error; 0 if the response is not acceptable (in which case the handshake will fail) or a positive value if it is acceptable. .PP The callback when used on the server side should return with either \&\s-1SSL_TLSEXT_ERR_OK\s0 (meaning that the \s-1OCSP\s0 response that has been set should be returned), \s-1SSL_TLSEXT_ERR_NOACK\s0 (meaning that an \s-1OCSP\s0 response should not be returned) or \s-1SSL_TLSEXT_ERR_ALERT_FATAL\s0 (meaning that a fatal error has occurred). .PP \&\fBSSL_CTX_set_tlsext_status_cb()\fR, \fBSSL_CTX_set_tlsext_status_arg()\fR, \&\fBSSL_CTX_set_tlsext_status_type()\fR, \fBSSL_set_tlsext_status_type()\fR and \&\fBSSL_set_tlsext_status_ocsp_resp()\fR return 0 on error or 1 on success. .PP \&\fBSSL_CTX_get_tlsext_status_type()\fR returns the value previously set by \&\fBSSL_CTX_set_tlsext_status_type()\fR, or \-1 if not set. .PP \&\fBSSL_get_tlsext_status_ocsp_resp()\fR returns the length of the \s-1OCSP\s0 response data or \-1 if there is no \s-1OCSP\s0 response data. .PP \&\fBSSL_get_tlsext_status_type()\fR returns \fBTLSEXT_STATUSTYPE_ocsp\fR on the client side if \fBSSL_set_tlsext_status_type()\fR was previously called, or on the server side if the client requested \s-1OCSP\s0 stapling.

If no match is found, the first item in \fBclient\fR, \fBclient_len\fR is returned in \fBout\fR, \fBoutlen\fR. This function can also be used in the \s-1NPN\s0 callback. .PP \&\fBSSL_CTX_set_next_proto_select_cb()\fR sets a callback \fBcb\fR that is called when a client needs to select a protocol from the server's provided list, and a user-defined pointer argument \fBarg\fR which will be passed to this callback. For the callback itself, \fBout\fR must be set to point to the selected protocol (which may be within \fBin\fR). The length of the protocol name must be written into \fBoutlen\fR. The server's advertised protocols are provided in \fBin\fR and \fBinlen\fR. The callback can assume that \fBin\fR is syntactically valid. The client must select a protocol. It is fatal to the connection if this callback returns a value other than \fB\s-1SSL_TLSEXT_ERR_OK\s0\fR. The \fBarg\fR parameter is the pointer set via \fBSSL_CTX_set_next_proto_select_cb()\fR. .PP \&\fBSSL_CTX_set_next_protos_advertised_cb()\fR sets a callback \fBcb\fR that is called when a \s-1TLS\s0 server needs a list of supported protocols for Next Protocol Negotiation. The returned list must be in protocol-list format, described below. The list is returned by setting \fBout\fR to point to it and \fBoutlen\fR to its length. This memory will not be modified, but the \fB\s-1SSL\s0\fR does keep a reference to it. The callback should return \fB\s-1SSL_TLSEXT_ERR_OK\s0\fR if it wishes to advertise. Otherwise, no such extension will be included in the ServerHello. .PP \&\fBSSL_get0_alpn_selected()\fR returns a pointer to the selected protocol in \fBdata\fR with length \fBlen\fR. It is not NUL-terminated. \fBdata\fR is set to \s-1NULL\s0 and \fBlen\fR is set to 0 if no protocol has been selected. \fBdata\fR must not be freed. .PP \&\fBSSL_get0_next_proto_negotiated()\fR sets \fBdata\fR and \fBlen\fR to point to the client's requested protocol for this connection. If the client did not request any protocol or \s-1NPN\s0 is not enabled, then \fBdata\fR is set to \s-1NULL\s0 and \&\fBlen\fR to 0. Note that the client can request any protocol it chooses. The value returned from this function need not be a member of the list of supported protocols provided by the callback. .SH "NOTES" .IX Header "NOTES" The protocol-lists must be in wire-format, which is defined as a vector of nonempty, 8\-bit length-prefixed, byte strings.

The first item in \fBclient\fR, \fBclient_len\fR is returned in \&\fBout\fR, \fBoutlen\fR. .PP The \s-1ALPN\s0 select callback \fBcb\fR, must return one of the following: .IP "\s-1SSL_TLSEXT_ERR_OK\s0" 4 .IX Item "SSL_TLSEXT_ERR_OK" \&\s-1ALPN\s0 protocol selected. .IP "\s-1SSL_TLSEXT_ERR_ALERT_FATAL\s0" 4 .IX Item "SSL_TLSEXT_ERR_ALERT_FATAL" There was no overlap between the client's supplied list and the server configuration. .IP "\s-1SSL_TLSEXT_ERR_NOACK\s0" 4 .IX Item "SSL_TLSEXT_ERR_NOACK" \&\s-1ALPN\s0 protocol not selected, e.g., because no \s-1ALPN\s0 protocols are configured for this connection. .PP The callback set using \fBSSL_CTX_set_next_proto_select_cb()\fR should return \&\fB\s-1SSL_TLSEXT_ERR_OK\s0\fR if successful. Any other value is fatal to the connection. .PP The callback set using \fBSSL_CTX_set_next_protos_advertised_cb()\fR should return \&\fB\s-1SSL_TLSEXT_ERR_OK\s0\fR if it wishes to advertise.

All settings (method, ciphers, BIOs) are kept. .SH "NOTES" .IX Header "NOTES" SSL_clear is used to prepare an \s-1SSL\s0 object for a new connection. While all settings are kept, a side effect is the handling of the current \s-1SSL\s0 session. If a session is still \fBopen\fR, it is considered bad and will be removed from the session cache, as required by \s-1RFC2246. A\s0 session is considered open, if \fBSSL_shutdown\fR\|(3) was not called for the connection or at least \fBSSL_set_shutdown\fR\|(3) was used to set the \s-1SSL_SENT_SHUTDOWN\s0 state. .PP If a session was closed cleanly, the session object will be kept and all settings corresponding. This explicitly means, that e.g. the special method used during the session will be kept for the next handshake. So if the session was a TLSv1 session, a \s-1SSL\s0 client object will use a TLSv1 client method for the next handshake and a \s-1SSL\s0 server object will use a TLSv1 server method, even if TLS_*_methods were chosen on startup. This will might lead to connection failures (see \fBSSL_new\fR\|(3)) for a description of the method's properties. .SH "WARNINGS" .IX Header "WARNINGS" \&\fBSSL_clear()\fR resets the \s-1SSL\s0 object to allow for another connection. The reset operation however keeps several settings of the last sessions (some of these settings were made automatically during the last handshake). It only makes sense for a new connection with the exact same peer that shares these settings, and may fail if that peer changes its settings between connections. Use the sequence \&\fBSSL_get_session\fR\|(3); \&\fBSSL_new\fR\|(3); \&\fBSSL_set_session\fR\|(3); \&\fBSSL_free\fR\|(3) instead to avoid such failures (or simply \fBSSL_free\fR\|(3); \fBSSL_new\fR\|(3) if session reuse is not desired). .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following return values can occur: .IP "0" 4 The \fBSSL_clear()\fR operation could not be performed.

The callback is inherited by all \fBssl\fR objects created from \fBctx\fR. .PP \&\fBSSL_CTX_set_tmp_dh()\fR sets \s-1DH\s0 parameters to be used to be \fBdh\fR. The key is inherited by all \fBssl\fR objects created from \fBctx\fR. .PP \&\fBSSL_set_tmp_dh_callback()\fR sets the callback only for \fBssl\fR. .PP \&\fBSSL_set_tmp_dh()\fR sets the parameters only for \fBssl\fR. .PP These functions apply to \s-1SSL/TLS\s0 servers only. .SH "NOTES" .IX Header "NOTES" When using a cipher with \s-1RSA\s0 authentication, an ephemeral \s-1DH\s0 key exchange can take place. Ciphers with \s-1DSA\s0 keys always use ephemeral \s-1DH\s0 keys as well. In these cases, the session data are negotiated using the ephemeral/temporary \s-1DH\s0 key and the key supplied and certified by the certificate chain is only used for signing. Anonymous ciphers (without a permanent server key) also use ephemeral \s-1DH\s0 keys. .PP Using ephemeral \s-1DH\s0 key exchange yields forward secrecy, as the connection can only be decrypted, when the \s-1DH\s0 key is known. By generating a temporary \&\s-1DH\s0 key inside the server application that is lost when the application is left, it becomes impossible for an attacker to decrypt past sessions, even if he gets hold of the normal (certified) key, as this key was only used for signing. .PP In order to perform a \s-1DH\s0 key exchange the server must use a \s-1DH\s0 group (\s-1DH\s0 parameters) and generate a \s-1DH\s0 key. The server will always generate a new \s-1DH\s0 key during the negotiation. .PP As generating \s-1DH\s0 parameters is extremely time consuming, an application should not generate the parameters on the fly but supply the parameters. \&\s-1DH\s0 parameters can be reused, as the actual key is newly generated during the negotiation. The risk in reusing \s-1DH\s0 parameters is that an attacker may specialize on a very often used \s-1DH\s0 group. Applications should therefore generate their own \s-1DH\s0 parameters during the installation process using the openssl \fBdhparam\fR\|(1) application. This application guarantees that \*(L"strong\*(R" primes are used. .PP Files dh2048.pem, and dh4096.pem in the 'apps' directory of the current version of the OpenSSL distribution contain the '\s-1SKIP\s0' \s-1DH\s0 parameters, which use safe primes and were generated verifiably pseudo-randomly. These files can be converted into C code using the \fB\-C\fR option of the \&\fBdhparam\fR\|(1) application. Generation of custom \s-1DH\s0 parameters during installation should still be preferred to stop an attacker from specializing on a commonly used group. File dh1024.pem contains old parameters that must not be used by applications. .PP An application may either directly specify the \s-1DH\s0 parameters or can supply the \s-1DH\s0 parameters via a callback function. .PP Previous versions of the callback used \fBis_export\fR and \fBkeylength\fR parameters to control parameter generation for export and non-export cipher suites. Modern servers that do not support export cipher suites are advised to either use \fBSSL_CTX_set_tmp_dh()\fR or alternatively, use the callback but ignore \fBkeylength\fR and \fBis_export\fR and simply supply at least 2048\-bit parameters in the callback. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set_tmp_dh_callback()\fR and \fBSSL_set_tmp_dh_callback()\fR do not return diagnostic output. .PP \&\fBSSL_CTX_set_tmp_dh()\fR and \fBSSL_set_tmp_dh()\fR do return 1 on success and 0 on failure.

Note however, that changes to these two instances apply only to the current thread. .PP For that reason it is recommended not to change the settings of these three instances directly. Instead, an application should change the default settings for new \s-1DRBG\s0 instances at initialization time, before creating additional threads. .PP During initialization, it is possible to change the reseed interval and reseed time interval.

A \s-1BIO\s0 pair is a pair of source/sink BIOs where data written to either half of the pair is buffered and can be read from the other half. Both halves must usually by handled by the same application thread since no locking is done on the internal data structures. .PP Since \s-1BIO\s0 chains typically end in a source/sink \s-1BIO\s0 it is possible to make this one half of a \s-1BIO\s0 pair and have all the data processed by the chain under application control. .PP One typical use of \s-1BIO\s0 pairs is to place \s-1TLS/SSL I/O\s0 under application control, this can be used when the application wishes to use a non standard transport for \&\s-1TLS/SSL\s0 or the normal socket routines are inappropriate. .PP Calls to \fBBIO_read_ex()\fR will read data from the buffer or request a retry if no data is available. .PP Calls to \fBBIO_write_ex()\fR will place data in the buffer or request a retry if the buffer is full. .PP The standard calls \fBBIO_ctrl_pending()\fR and \fBBIO_ctrl_wpending()\fR can be used to determine the amount of pending data in the read or write buffer. .PP \&\fBBIO_reset()\fR clears any data in the write buffer. .PP \&\fBBIO_make_bio_pair()\fR joins two separate BIOs into a connected pair. .PP \&\fBBIO_destroy_pair()\fR destroys the association between two connected BIOs. Freeing up any half of the pair will automatically destroy the association. .PP \&\fBBIO_shutdown_wr()\fR is used to close down a \s-1BIO\s0 \fBb\fR. After this call no further writes on \s-1BIO\s0 \fBb\fR are allowed (they will return an error). Reads on the other half of the pair will return any pending data or \s-1EOF\s0 when all pending data has been read. .PP \&\fBBIO_set_write_buf_size()\fR sets the write buffer size of \s-1BIO\s0 \fBb\fR to \fBsize\fR. If the size is not initialized a default value is used. This is currently 17K, sufficient for a maximum size \s-1TLS\s0 record. .PP \&\fBBIO_get_write_buf_size()\fR returns the size of the write buffer. .PP \&\fBBIO_new_bio_pair()\fR combines the calls to \fBBIO_new()\fR, \fBBIO_make_bio_pair()\fR and \&\fBBIO_set_write_buf_size()\fR to create a connected pair of BIOs \fBbio1\fR, \fBbio2\fR with write buffer sizes \fBwritebuf1\fR and \fBwritebuf2\fR. If either size is zero then the default size is used. \fBBIO_new_bio_pair()\fR does not check whether \&\fBbio1\fR or \fBbio2\fR do point to some other \s-1BIO,\s0 the values are overwritten, \&\fBBIO_free()\fR is not called. .PP \&\fBBIO_get_write_guarantee()\fR and \fBBIO_ctrl_get_write_guarantee()\fR return the maximum length of data that can be currently written to the \s-1BIO.\s0 Writes larger than this value will return a value from \fBBIO_write_ex()\fR less than the amount requested or if the buffer is full request a retry. \fBBIO_ctrl_get_write_guarantee()\fR is a function whereas \fBBIO_get_write_guarantee()\fR is a macro. .PP \&\fBBIO_get_read_request()\fR and \fBBIO_ctrl_get_read_request()\fR return the amount of data requested, or the buffer size if it is less, if the last read attempt at the other half of the \s-1BIO\s0 pair failed due to an empty buffer. This can be used to determine how much data should be written to the \s-1BIO\s0 so the next read will succeed: this is most useful in \s-1TLS/SSL\s0 applications where the amount of data read is usually meaningful rather than just a buffer size. After a successful read this call will return zero. It also will return zero once new data has been written satisfying the read request or part of it. Note that \fBBIO_get_read_request()\fR never returns an amount larger than that returned by \fBBIO_get_write_guarantee()\fR. .PP \&\fBBIO_ctrl_reset_read_request()\fR can also be used to reset the value returned by \&\fBBIO_get_read_request()\fR to zero. .SH "NOTES" .IX Header "NOTES" Both halves of a \s-1BIO\s0 pair should be freed. That is even if one half is implicit freed due to a \fBBIO_free_all()\fR or \fBSSL_free()\fR call the other half needs to be freed. .PP When used in bidirectional applications (such as \s-1TLS/SSL\s0) care should be taken to flush any data in the write buffer. This can be done by calling \fBBIO_pending()\fR on the other half of the pair and, if any data is pending, reading it and sending it to the underlying transport. This must be done before any normal processing (such as calling \fBselect()\fR ) due to a request and \fBBIO_should_read()\fR being true. .PP To see why this is important consider a case where a request is sent using \&\fBBIO_write_ex()\fR and a response read with \fBBIO_read_ex()\fR, this can occur during an \&\s-1TLS/SSL\s0 handshake for example. \fBBIO_write_ex()\fR will succeed and place data in the write buffer. \fBBIO_read_ex()\fR will initially fail and \fBBIO_should_read()\fR will be true. If the application then waits for data to be available on the underlying transport before flushing the write buffer it will never succeed because the request was never sent! .PP \&\fBBIO_eof()\fR is true if no data is in the peer \s-1BIO\s0 and the peer \s-1BIO\s0 has been shutdown. .PP \&\fBBIO_make_bio_pair()\fR, \fBBIO_destroy_bio_pair()\fR, \fBBIO_shutdown_wr()\fR, \&\fBBIO_set_write_buf_size()\fR, \fBBIO_get_write_buf_size()\fR, \&\fBBIO_get_write_guarantee()\fR, and \fBBIO_get_read_request()\fR are implemented as macros. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_new_bio_pair()\fR returns 1 on success, with the new BIOs available in \&\fBbio1\fR and \fBbio2\fR, or 0 on failure, with \s-1NULL\s0 pointers stored into the locations for \fBbio1\fR and \fBbio2\fR. Check the error stack for more information. .PP [\s-1XXXXX:\s0 More return values need to be added here] .SH "EXAMPLES" .IX Header "EXAMPLES" The \s-1BIO\s0 pair can be used to have full control over the network access of an application.

Then the application has to flush the write buffer and/or fill the read buffer. .PP Use the \fBBIO_ctrl_pending()\fR, to find out whether data is buffered in the \s-1BIO\s0 and must be transferred to the network. Use \fBBIO_ctrl_get_read_request()\fR to find out, how many bytes must be written into the buffer before the \&\fBSSL_operation()\fR can successfully be continued. .SH "WARNINGS" .IX Header "WARNINGS" As the data is buffered, \fBSSL_operation()\fR may return with an \s-1ERROR_SSL_WANT_READ\s0 condition, but there is still data in the write buffer. An application must not rely on the error value of \fBSSL_operation()\fR but must assure that the write buffer is always flushed first. Otherwise a deadlock may occur as the peer might be waiting for the data before being able to continue. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_set_bio\fR\|(3), \fBssl\fR\|(7), \fBbio\fR\|(7), \&\fBBIO_should_retry\fR\|(3), \fBBIO_read_ex\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

If \fBpctx\fR is not \s-1NULL,\s0 the \&\s-1EVP_PKEY_CTX\s0 of the verification operation will be written to \fB*pctx\fR: this can be used to set alternative verification options. Note that any existing value in \fB*pctx\fR is overwritten. The \s-1EVP_PKEY_CTX\s0 value returned must not be freed directly by the application if \fBctx\fR is not assigned an \s-1EVP_PKEY_CTX\s0 value before being passed to \fBEVP_DigestVerifyInit()\fR (which means the \s-1EVP_PKEY_CTX\s0 is created inside \fBEVP_DigestVerifyInit()\fR and it will be freed automatically when the \&\s-1EVP_MD_CTX\s0 is freed). .PP No \fB\s-1EVP_PKEY_CTX\s0\fR will be created by \fBEVP_DigestSignInit()\fR if the passed \fBctx\fR has already been assigned one via \fBEVP_MD_CTX_set_pkey_ctx\fR\|(3). See also \s-1\fBSM2\s0\fR\|(7). .PP \&\fBEVP_DigestVerifyUpdate()\fR hashes \fBcnt\fR bytes of data at \fBd\fR into the verification context \fBctx\fR. This function can be called several times on the same \fBctx\fR to include additional data. This function is currently implemented using a macro. .PP \&\fBEVP_DigestVerifyFinal()\fR verifies the data in \fBctx\fR against the signature in \&\fBsig\fR of length \fBsiglen\fR. .PP \&\fBEVP_DigestVerify()\fR verifies \fBtbslen\fR bytes at \fBtbs\fR against the signature in \fBsig\fR of length \fBsiglen\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_DigestVerifyInit()\fR and \fBEVP_DigestVerifyUpdate()\fR return 1 for success and 0 for failure. .PP \&\fBEVP_DigestVerifyFinal()\fR and \fBEVP_DigestVerify()\fR return 1 for success; any other value indicates failure. A return value of zero indicates that the signature did not verify successfully (that is, \fBtbs\fR did not match the original data or the signature had an invalid form), while other values indicate a more serious error (and sometimes also indicate an invalid signature form). .PP The error codes can be obtained from \fBERR_get_error\fR\|(3). .SH "NOTES" .IX Header "NOTES" The \fB\s-1EVP\s0\fR interface to digital signatures should almost always be used in preference to the low-level interfaces. This is because the code then becomes transparent to the algorithm used and much more flexible. .PP \&\fBEVP_DigestVerify()\fR is a one shot operation which verifies a single block of data in one function. For algorithms that support streaming it is equivalent to calling \fBEVP_DigestVerifyUpdate()\fR and \fBEVP_DigestVerifyFinal()\fR. For algorithms which do not support streaming (e.g. PureEdDSA) it is the only way to verify data. .PP In previous versions of OpenSSL there was a link between message digest types and public key algorithms. This meant that \*(L"clone\*(R" digests such as \fBEVP_dss1()\fR needed to be used to sign using \s-1SHA1\s0 and \s-1DSA.\s0 This is no longer necessary and the use of clone digest is now discouraged. .PP For some key types and parameters the random number generator must be seeded. If the automatic seeding or reseeding of the OpenSSL \s-1CSPRNG\s0 fails due to external circumstances (see \s-1\fBRAND\s0\fR\|(7)), the operation will fail. .PP The call to \fBEVP_DigestVerifyFinal()\fR internally finalizes a copy of the digest context. This means that \fBEVP_VerifyUpdate()\fR and \fBEVP_VerifyFinal()\fR can be called later to digest and verify additional data. .PP Since only a copy of the digest context is ever finalized, the context must be cleaned up after use by calling \fBEVP_MD_CTX_free()\fR or a memory leak will occur. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_DigestSignInit\fR\|(3), \&\fBEVP_DigestInit\fR\|(3), \&\fBevp\fR\|(7), \s-1\fBHMAC\s0\fR\|(3), \s-1\fBMD2\s0\fR\|(3), \&\s-1\fBMD5\s0\fR\|(3), \s-1\fBMDC2\s0\fR\|(3), \s-1\fBRIPEMD160\s0\fR\|(3), \&\s-1\fBSHA1\s0\fR\|(3), \fBdgst\fR\|(1), \&\s-1\fBRAND\s0\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" \&\fBEVP_DigestVerifyInit()\fR, \fBEVP_DigestVerifyUpdate()\fR and \fBEVP_DigestVerifyFinal()\fR were added in OpenSSL 1.0.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2006\-2020 The OpenSSL Project Authors.

It is called before a certificate will be used by a client or server. The callback can then inspect the passed \fBssl\fR structure and set or clear any appropriate certificates. If the callback is successful it \fB\s-1MUST\s0\fR return 1 even if no certificates have been set. A zero is returned on error which will abort the handshake with a fatal internal error alert. A negative return value will suspend the handshake and the handshake function will return immediately. \&\fBSSL_get_error\fR\|(3) will return \s-1SSL_ERROR_WANT_X509_LOOKUP\s0 to indicate, that the handshake was suspended. The next call to the handshake function will again lead to the call of \fBcert_cb()\fR. It is the job of the \&\fBcert_cb()\fR to store information about the state of the last call, if required to continue. .SH "NOTES" .IX Header "NOTES" An application will typically call \fBSSL_use_certificate()\fR and \&\fBSSL_use_PrivateKey()\fR to set the end entity certificate and private key. It can add intermediate and optionally the root \s-1CA\s0 certificates using \&\fBSSL_add1_chain_cert()\fR. .PP It might also call \fBSSL_certs_clear()\fR to delete any certificates associated with the \fB\s-1SSL\s0\fR object. .PP The certificate callback functionality supersedes the (largely broken) functionality provided by the old client certificate callback interface. It is \fBalways\fR called even is a certificate is already set so the callback can modify or delete the existing certificate. .PP A more advanced callback might examine the handshake parameters and set whatever chain is appropriate. For example a legacy client supporting only TLSv1.0 might receive a certificate chain signed using \s-1SHA1\s0 whereas a TLSv1.2 or later client which advertises support for \s-1SHA256\s0 could receive a chain using \s-1SHA256.\s0 .PP Normal server sanity checks are performed on any certificates set by the callback. So if an \s-1EC\s0 chain is set for a curve the client does not support it will \fBnot\fR be used. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set_cert_cb()\fR and \fBSSL_set_cert_cb()\fR do not return values. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_use_certificate\fR\|(3), \&\fBSSL_add1_chain_cert\fR\|(3), \&\fBSSL_get_client_CA_list\fR\|(3), \&\fBSSL_clear\fR\|(3), \fBSSL_free\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2014\-2018 The OpenSSL Project Authors.

This is a wrapper round the platform's \s-1TCP/IP\s0 socket accept routines. .PP Using accept BIOs, \s-1TCP/IP\s0 connections can be accepted and data transferred using only \s-1BIO\s0 routines. In this way any platform specific operations are hidden by the \s-1BIO\s0 abstraction. .PP Read and write operations on an accept \s-1BIO\s0 will perform I/O on the underlying connection. If no connection is established and the port (see below) is set up properly then the \s-1BIO\s0 waits for an incoming connection. .PP Accept BIOs support \fBBIO_puts()\fR but not \fBBIO_gets()\fR. .PP If the close flag is set on an accept \s-1BIO\s0 then any active connection on that chain is shutdown and the socket closed when the \s-1BIO\s0 is freed. .PP Calling \fBBIO_reset()\fR on an accept \s-1BIO\s0 will close any active connection and reset the \s-1BIO\s0 into a state where it awaits another incoming connection. .PP \&\fBBIO_get_fd()\fR and \fBBIO_set_fd()\fR can be called to retrieve or set the accept socket. See \fBBIO_s_fd\fR\|(3) .PP \&\fBBIO_set_accept_name()\fR uses the string \fBname\fR to set the accept name. The name is represented as a string of the form \*(L"host:port\*(R", where \*(L"host\*(R" is the interface to use and \*(L"port\*(R" is the port. The host can be \*(L"*\*(R" or empty which is interpreted as meaning any interface. If the host is an IPv6 address, it has to be enclosed in brackets, for example \*(L"[::1]:https\*(R". \*(L"port\*(R" has the same syntax as the port specified in \fBBIO_set_conn_port()\fR for connect BIOs, that is it can be a numerical port string or a string to lookup using \fBgetservbyname()\fR and a string table. .PP \&\fBBIO_set_accept_port()\fR uses the string \fBport\fR to set the accept port. \*(L"port\*(R" has the same syntax as the port specified in \&\fBBIO_set_conn_port()\fR for connect BIOs, that is it can be a numerical port string or a string to lookup using \fBgetservbyname()\fR and a string table. .PP \&\fBBIO_new_accept()\fR combines \fBBIO_new()\fR and \fBBIO_set_accept_name()\fR into a single call: that is it creates a new accept \s-1BIO\s0 with port \&\fBhost_port\fR. .PP \&\fBBIO_set_nbio_accept()\fR sets the accept socket to blocking mode (the default) if \fBn\fR is 0 or non blocking mode if \fBn\fR is 1. .PP \&\fBBIO_set_accept_bios()\fR can be used to set a chain of BIOs which will be duplicated and prepended to the chain when an incoming connection is received. This is useful if, for example, a buffering or \s-1SSL BIO\s0 is required for each connection. The chain of BIOs must not be freed after this call, they will be automatically freed when the accept \s-1BIO\s0 is freed. .PP \&\fBBIO_set_bind_mode()\fR and \fBBIO_get_bind_mode()\fR set and retrieve the current bind mode. If \fB\s-1BIO_BIND_NORMAL\s0\fR (the default) is set then another socket cannot be bound to the same port. If \&\fB\s-1BIO_BIND_REUSEADDR\s0\fR is set then other sockets can bind to the same port. If \fB\s-1BIO_BIND_REUSEADDR_IF_UNUSED\s0\fR is set then and attempt is first made to use \s-1BIO_BIN_NORMAL,\s0 if this fails and the port is not in use then a second attempt is made using \fB\s-1BIO_BIND_REUSEADDR\s0\fR. .PP \&\fBBIO_do_accept()\fR serves two functions. When it is first called, after the accept \s-1BIO\s0 has been setup, it will attempt to create the accept socket and bind an address to it. Second and subsequent calls to \fBBIO_do_accept()\fR will await an incoming connection, or request a retry in non blocking mode. .SH "NOTES" .IX Header "NOTES" When an accept \s-1BIO\s0 is at the end of a chain it will await an incoming connection before processing I/O calls. When an accept \&\s-1BIO\s0 is not at then end of a chain it passes I/O calls to the next \&\s-1BIO\s0 in the chain. .PP When a connection is established a new socket \s-1BIO\s0 is created for the connection and appended to the chain. That is the chain is now accept\->socket. This effectively means that attempting I/O on an initial accept socket will await an incoming connection then perform I/O on it. .PP If any additional BIOs have been set using \fBBIO_set_accept_bios()\fR then they are placed between the socket and the accept \s-1BIO,\s0 that is the chain will be accept\->otherbios\->socket. .PP If a server wishes to process multiple connections (as is normally the case) then the accept \s-1BIO\s0 must be made available for further incoming connections. This can be done by waiting for a connection and then calling: .PP .Vb 1 \& connection = BIO_pop(accept); .Ve .PP After this call \fBconnection\fR will contain a \s-1BIO\s0 for the recently established connection and \fBaccept\fR will now be a single \s-1BIO\s0 again which can be used to await further incoming connections. If no further connections will be accepted the \fBaccept\fR can be freed using \fBBIO_free()\fR. .PP If only a single connection will be processed it is possible to perform I/O using the accept \s-1BIO\s0 itself. This is often undesirable however because the accept \s-1BIO\s0 will still accept additional incoming connections. This can be resolved by using \fBBIO_pop()\fR (see above) and freeing up the accept \s-1BIO\s0 after the initial connection. .PP If the underlying accept socket is nonblocking and \fBBIO_do_accept()\fR is called to await an incoming connection it is possible for \&\fBBIO_should_io_special()\fR with the reason \s-1BIO_RR_ACCEPT.\s0 If this happens then it is an indication that an accept attempt would block: the application should take appropriate action to wait until the underlying socket has accepted a connection and retry the call. .PP \&\fBBIO_set_accept_name()\fR, \fBBIO_get_accept_name()\fR, \fBBIO_set_accept_port()\fR, \&\fBBIO_get_accept_port()\fR, \fBBIO_set_nbio_accept()\fR, \fBBIO_set_accept_bios()\fR, \&\fBBIO_get_peer_name()\fR, \fBBIO_get_peer_port()\fR, \&\fBBIO_get_accept_ip_family()\fR, \fBBIO_set_accept_ip_family()\fR, \&\fBBIO_set_bind_mode()\fR, \fBBIO_get_bind_mode()\fR and \fBBIO_do_accept()\fR are macros. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_do_accept()\fR, \&\fBBIO_set_accept_name()\fR, \fBBIO_set_accept_port()\fR, \fBBIO_set_nbio_accept()\fR, \&\fBBIO_set_accept_bios()\fR, \fBBIO_set_accept_ip_family()\fR, and \fBBIO_set_bind_mode()\fR return 1 for success and 0 or \-1 for failure. .PP \&\fBBIO_get_accept_name()\fR returns the accept name or \s-1NULL\s0 on error. \&\fBBIO_get_peer_name()\fR returns the peer name or \s-1NULL\s0 on error. .PP \&\fBBIO_get_accept_port()\fR returns the accept port as a string or \s-1NULL\s0 on error. \&\fBBIO_get_peer_port()\fR returns the peer port as a string or \s-1NULL\s0 on error. \&\fBBIO_get_accept_ip_family()\fR returns the \s-1IP\s0 family or \-1 on error. .PP \&\fBBIO_get_bind_mode()\fR returns the set of \fB\s-1BIO_BIND\s0\fR flags, or \-1 on failure. .PP \&\fBBIO_new_accept()\fR returns a \s-1BIO\s0 or \s-1NULL\s0 on error. .SH "EXAMPLES" .IX Header "EXAMPLES" This example accepts two connections on port 4444, sends messages down each and finally closes both down. .PP .Vb 1 \& BIO *abio, *cbio, *cbio2; \& \& /* First call to BIO_accept() sets up accept BIO */ \& abio = BIO_new_accept("4444"); \& if (BIO_do_accept(abio) <= 0) { \& fprintf(stderr, "Error setting up accept\en"); \& ERR_print_errors_fp(stderr); \& exit(1); \& } \& \& /* Wait for incoming connection */ \& if (BIO_do_accept(abio) <= 0) { \& fprintf(stderr, "Error accepting connection\en"); \& ERR_print_errors_fp(stderr); \& exit(1); \& } \& fprintf(stderr, "Connection 1 established\en"); \& \& /* Retrieve BIO for connection */ \& cbio = BIO_pop(abio); \& BIO_puts(cbio, "Connection 1: Sending out Data on initial connection\en"); \& fprintf(stderr, "Sent out data on connection 1\en"); \& \& /* Wait for another connection */ \& if (BIO_do_accept(abio) <= 0) { \& fprintf(stderr, "Error accepting connection\en"); \& ERR_print_errors_fp(stderr); \& exit(1); \& } \& fprintf(stderr, "Connection 2 established\en"); \& \& /* Close accept BIO to refuse further connections */ \& cbio2 = BIO_pop(abio); \& BIO_free(abio); \& BIO_puts(cbio2, "Connection 2: Sending out Data on second\en"); \& fprintf(stderr, "Sent out data on connection 2\en"); \& \& BIO_puts(cbio, "Connection 1: Second connection established\en"); \& \& /* Close the two established connections */ \& BIO_free(cbio); \& BIO_free(cbio2); .Ve .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

For example: .PP .Vb 4 \& \-\-\-\-\-BEGIN PRIVATE KEY\-\-\-\-\- \& MIICdg.... \& ... bhTQ== \& \-\-\-\-\-END PRIVATE KEY\-\-\-\-\- .Ve .PP Optional header line(s) may appear after the begin line, and their existence depends on the type of object being written or read. .PP \&\fBPEM_write()\fR writes to the file \fBfp\fR, while \fBPEM_write_bio()\fR writes to the \s-1BIO\s0 \fBbp\fR. The \fBname\fR is the name to use in the marker, the \&\fBheader\fR is the header value or \s-1NULL,\s0 and \fBdata\fR and \fBlen\fR specify the data and its length. .PP The final \fBdata\fR buffer is typically an \s-1ASN.1\s0 object which can be decoded with the \fBd2i\fR function appropriate to the type \fBname\fR; see \fBd2i_X509\fR\|(3) for examples. .PP \&\fBPEM_read()\fR reads from the file \fBfp\fR, while \fBPEM_read_bio()\fR reads from the \s-1BIO\s0 \fBbp\fR. Both skip any non-PEM data that precedes the start of the next \s-1PEM\s0 object. When an object is successfully retrieved, the type name from the \*(L"\-\-\-\-BEGIN <type>\-\-\-\-\-\*(R" is returned via the \fBname\fR argument, any encapsulation headers are returned in \fBheader\fR and the base64\-decoded content and its length are returned via \fBdata\fR and \fBlen\fR respectively. The \fBname\fR, \fBheader\fR and \fBdata\fR pointers are allocated via \fBOPENSSL_malloc()\fR and should be freed by the caller via \fBOPENSSL_free()\fR when no longer needed. .PP \&\fBPEM_get_EVP_CIPHER_INFO()\fR can be used to determine the \fBdata\fR returned by \&\fBPEM_read()\fR or \fBPEM_read_bio()\fR is encrypted and to retrieve the associated cipher and \s-1IV.\s0 The caller passes a pointer to structure of type \fB\s-1EVP_CIPHER_INFO\s0\fR via the \&\fBcinfo\fR argument and the \fBheader\fR returned via \fBPEM_read()\fR or \fBPEM_read_bio()\fR. If the call is successful 1 is returned and the cipher and \s-1IV\s0 are stored at the address pointed to by \fBcinfo\fR. When the header is malformed, or not supported or when the cipher is unknown or some internal error happens 0 is returned. This function is deprecated, see \fB\s-1NOTES\s0\fR below. .PP \&\fBPEM_do_header()\fR can then be used to decrypt the data if the header indicates encryption. The \fBcinfo\fR argument is a pointer to the structure initialized by the previous call to \fBPEM_get_EVP_CIPHER_INFO()\fR. The \fBdata\fR and \fBlen\fR arguments are those returned by the previous call to \&\fBPEM_read()\fR or \fBPEM_read_bio()\fR. The \fBcb\fR and \fBu\fR arguments make it possible to override the default password prompt function as described in \fBPEM_read_PrivateKey\fR\|(3). On successful completion the \fBdata\fR is decrypted in place, and \fBlen\fR is updated to indicate the plaintext length. This function is deprecated, see \fB\s-1NOTES\s0\fR below. .PP If the data is a priori known to not be encrypted, then neither \fBPEM_do_header()\fR nor \fBPEM_get_EVP_CIPHER_INFO()\fR need be called. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBPEM_read()\fR and \fBPEM_read_bio()\fR return 1 on success and 0 on failure, the latter includes the case when no more \s-1PEM\s0 objects remain in the input file. To distinguish end of file from more serious errors the caller must peek at the error stack and check for \fB\s-1PEM_R_NO_START_LINE\s0\fR, which indicates that no more \&\s-1PEM\s0 objects were found. See \fBERR_peek_last_error\fR\|(3), \s-1\fBERR_GET_REASON\s0\fR\|(3). .PP \&\fBPEM_get_EVP_CIPHER_INFO()\fR and \fBPEM_do_header()\fR return 1 on success, and 0 on failure. The \fBdata\fR is likely meaningless if these functions fail. .SH "NOTES" .IX Header "NOTES" The \fBPEM_get_EVP_CIPHER_INFO()\fR and \fBPEM_do_header()\fR functions are deprecated. This is because the underlying \s-1PEM\s0 encryption format is obsolete, and should be avoided. It uses an encryption format with an OpenSSL-specific key-derivation function, which employs \s-1MD5\s0 with an iteration count of 1! Instead, private keys should be stored in PKCS#8 form, with a strong PKCS#5 v2.0 \s-1PBE.\s0 See \fBPEM_write_PrivateKey\fR\|(3) and \fBd2i_PKCS8PrivateKey_bio\fR\|(3). .PP \&\fBPEM_do_header()\fR makes no assumption regarding the pass phrase received from the password callback. It will simply be treated as a byte sequence. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBERR_peek_last_error\fR\|(3), \s-1\fBERR_GET_LIB\s0\fR\|(3), \&\fBd2i_PKCS8PrivateKey_bio\fR\|(3), \&\fBpassphrase\-encoding\fR\|(7) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 1998\-2018 The OpenSSL Project Authors.

The general method to do so is to \*(L"open\*(R" the \s-1URI\s0 using \fBOSSL_STORE_open()\fR, read each available and supported object using \fBOSSL_STORE_load()\fR as long as \&\fBOSSL_STORE_eof()\fR hasn't been reached, and finish it off with \fBOSSL_STORE_close()\fR. .PP The retrieved information is stored in a \fB\s-1OSSL_STORE_INFO\s0\fR, which is further described in \s-1\fBOSSL_STORE_INFO\s0\fR\|(3). .SS "Types" .IX Subsection "Types" \&\fB\s-1OSSL_STORE_CTX\s0\fR is a context variable that holds all the internal information for \fBOSSL_STORE_open()\fR, \fBOSSL_STORE_load()\fR, \fBOSSL_STORE_eof()\fR and \&\fBOSSL_STORE_close()\fR to work together. .SS "Functions" .IX Subsection "Functions" \&\fBOSSL_STORE_open()\fR takes a uri or path \fIuri\fR, password \s-1UI\s0 method \&\fIui_method\fR with associated data \fIui_data\fR, and post processing callback \fIpost_process\fR with associated data \fIpost_process_data\fR, opens a channel to the data located at that \s-1URI\s0 and returns a \&\fB\s-1OSSL_STORE_CTX\s0\fR with all necessary internal information. The given \fIui_method\fR and \fIui_data\fR will be reused by all functions that use \fB\s-1OSSL_STORE_CTX\s0\fR when interaction is needed, for instance to provide a password. The given \fIpost_process\fR and \fIpost_process_data\fR will be reused by \&\fBOSSL_STORE_load()\fR to manipulate or drop the value to be returned. The \fIpost_process\fR function drops values by returning \s-1NULL,\s0 which will cause \fBOSSL_STORE_load()\fR to start its process over with loading the next object, until \fIpost_process\fR returns something other than \&\s-1NULL,\s0 or the end of data is reached as indicated by \fBOSSL_STORE_eof()\fR. .PP \&\fBOSSL_STORE_ctrl()\fR takes a \fB\s-1OSSL_STORE_CTX\s0\fR, and command number \fIcmd\fR and more arguments not specified here. The available loader specific command numbers and arguments they each take depends on the loader that's used and is documented together with that loader. .PP There are also global controls available: .IP "\fB\s-1OSSL_STORE_C_USE_SECMEM\s0\fR" 4 .IX Item "OSSL_STORE_C_USE_SECMEM" Controls if the loader should attempt to use secure memory for any allocated \fB\s-1OSSL_STORE_INFO\s0\fR and its contents. This control expects one argument, a pointer to an \fBint\fR that is expected to have the value 1 (yes) or 0 (no). Any other value is an error. .PP \&\fBOSSL_STORE_load()\fR takes a \fB\s-1OSSL_STORE_CTX\s0\fR, tries to load the next available object and return it wrapped with \fB\s-1OSSL_STORE_INFO\s0\fR. .PP \&\fBOSSL_STORE_eof()\fR takes a \fB\s-1OSSL_STORE_CTX\s0\fR and checks if we've reached the end of data. .PP \&\fBOSSL_STORE_error()\fR takes a \fB\s-1OSSL_STORE_CTX\s0\fR and checks if an error occurred in the last \fBOSSL_STORE_load()\fR call. Note that it may still be meaningful to try and load more objects, unless \&\fBOSSL_STORE_eof()\fR shows that the end of data has been reached. .PP \&\fBOSSL_STORE_close()\fR takes a \fB\s-1OSSL_STORE_CTX\s0\fR, closes the channel that was opened by \fBOSSL_STORE_open()\fR and frees all other information that was stored in the \&\fB\s-1OSSL_STORE_CTX\s0\fR, as well as the \fB\s-1OSSL_STORE_CTX\s0\fR itself. If \fIctx\fR is \s-1NULL\s0 it does nothing. .SH "SUPPORTED SCHEMES" .IX Header "SUPPORTED SCHEMES" The basic supported scheme is \fBfile:\fR. Any other scheme can be added dynamically, using \&\fBOSSL_STORE_register_loader()\fR. .SH "NOTES" .IX Header "NOTES" A string without a scheme prefix (that is, a non-URI string) is implicitly interpreted as using the \fIfile:\fR scheme. .PP There are some tools that can be used together with \&\fBOSSL_STORE_open()\fR to determine if any failure is caused by an unparsable \&\s-1URI,\s0 or if it's a different error (such as memory allocation failures); if the \s-1URI\s0 was parsable but the scheme unregistered, the top error will have the reason \f(CW\*(C`OSSL_STORE_R_UNREGISTERED_SCHEME\*(C'\fR. .PP These functions make no direct assumption regarding the pass phrase received from the password callback. The loaders may make assumptions, however. For example, the \fBfile:\fR scheme loader inherits the assumptions made by OpenSSL functionality that handles the different file types; this is mostly relevant for PKCS#12 objects. See \fBpassphrase\-encoding\fR\|(7) for further information. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOSSL_STORE_open()\fR returns a pointer to a \fB\s-1OSSL_STORE_CTX\s0\fR on success, or \&\s-1NULL\s0 on failure. .PP \&\fBOSSL_STORE_load()\fR returns a pointer to a \fB\s-1OSSL_STORE_INFO\s0\fR on success, or \&\s-1NULL\s0 on error or when end of data is reached. Use \fBOSSL_STORE_error()\fR and \fBOSSL_STORE_eof()\fR to determine the meaning of a returned \s-1NULL.\s0 .PP \&\fBOSSL_STORE_eof()\fR returns 1 if the end of data has been reached, otherwise 0. .PP \&\fBOSSL_STORE_error()\fR returns 1 if an error occurred in an \fBOSSL_STORE_load()\fR call, otherwise 0. .PP \&\fBOSSL_STORE_ctrl()\fR and \fBOSSL_STORE_close()\fR returns 1 on success, or 0 on failure. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBossl_store\fR\|(7), \s-1\fBOSSL_STORE_INFO\s0\fR\|(3), \fBOSSL_STORE_register_loader\fR\|(3), \&\fBpassphrase\-encoding\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" \&\s-1\fBOSSL_STORE_CTX\s0()\fR, \fBOSSL_STORE_post_process_info_fn()\fR, \fBOSSL_STORE_open()\fR, \&\fBOSSL_STORE_ctrl()\fR, \fBOSSL_STORE_load()\fR, \fBOSSL_STORE_eof()\fR and \fBOSSL_STORE_close()\fR were added in OpenSSL 1.1.1. .PP Handling of \s-1NULL\s0 \fIctx\fR argument for \fBOSSL_STORE_close()\fR was introduced in OpenSSL 1.1.1h. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2020 The OpenSSL Project Authors.

If the application does not explicitly specify a verification callback function, the built-in verification function is used. If a verification callback \fIcallback\fR is specified via \&\fBSSL_CTX_set_cert_verify_callback()\fR, the supplied callback function is called instead. By setting \fIcallback\fR to \s-1NULL,\s0 the default behaviour is restored. .PP When the verification must be performed, \fIcallback\fR will be called with the arguments callback(X509_STORE_CTX *x509_store_ctx, void *arg).

If \s-1SSL_VERIFY_PEER\s0 is set and \fIcallback\fR returns 0, the handshake will fail.

The reference count of the \fB\s-1SSL_SESSION\s0\fR is not incremented, so that the pointer can become invalid by other operations. .PP \&\fBSSL_get0_session()\fR is the same as \fBSSL_get_session()\fR. .PP \&\fBSSL_get1_session()\fR is the same as \fBSSL_get_session()\fR, but the reference count of the \fB\s-1SSL_SESSION\s0\fR is incremented by one. .SH "NOTES" .IX Header "NOTES" The ssl session contains all information required to re-establish the connection without a full handshake for \s-1SSL\s0 versions up to and including TLSv1.2. In TLSv1.3 the same is true, but sessions are established after the main handshake has occurred. The server will send the session information to the client at a time of its choosing, which may be some while after the initial connection is established (or never). Calling these functions on the client side in TLSv1.3 before the session has been established will still return an \&\s-1SSL_SESSION\s0 object but that object cannot be used for resuming the session. See \&\fBSSL_SESSION_is_resumable\fR\|(3) for information on how to determine whether an \&\s-1SSL_SESSION\s0 object can be used for resumption or not. .PP Additionally, in TLSv1.3, a server can send multiple messages that establish a session for a single connection. In that case, on the client side, the above functions will only return information on the last session that was received. On the server side they will only return information on the last session that was sent, or if no session tickets were sent then the session for the current connection. .PP The preferred way for applications to obtain a resumable \s-1SSL_SESSION\s0 object is to use a new session callback as described in \fBSSL_CTX_sess_set_new_cb\fR\|(3). The new session callback is only invoked when a session is actually established, so this avoids the problem described above where an application obtains an \&\s-1SSL_SESSION\s0 object that cannot be used for resumption in TLSv1.3. It also enables applications to obtain information about all sessions sent by the server. .PP A session will be automatically removed from the session cache and marked as non-resumable if the connection is not closed down cleanly, e.g. if a fatal error occurs on the connection or \fBSSL_shutdown\fR\|(3) is not called prior to \&\fBSSL_free\fR\|(3). .PP In TLSv1.3 it is recommended that each \s-1SSL_SESSION\s0 object is only used for resumption once. .PP \&\fBSSL_get0_session()\fR returns a pointer to the actual session. As the reference counter is not incremented, the pointer is only valid while the connection is in use. If \fBSSL_clear\fR\|(3) or \&\fBSSL_free\fR\|(3) is called, the session may be removed completely (if considered bad), and the pointer obtained will become invalid. Even if the session is valid, it can be removed at any time due to timeout during \fBSSL_CTX_flush_sessions\fR\|(3). .PP If the data is to be kept, \fBSSL_get1_session()\fR will increment the reference count, so that the session will not be implicitly removed by other operations but stays in memory. In order to remove the session \&\fBSSL_SESSION_free\fR\|(3) must be explicitly called once to decrement the reference count again. .PP \&\s-1SSL_SESSION\s0 objects keep internal link information about the session cache list, when being inserted into one \s-1SSL_CTX\s0 object's session cache. One \s-1SSL_SESSION\s0 object, regardless of its reference count, must therefore only be used with one \s-1SSL_CTX\s0 object (and the \s-1SSL\s0 objects created from this \s-1SSL_CTX\s0 object). .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following return values can occur: .IP "\s-1NULL\s0" 4 .IX Item "NULL" There is no session available in \fBssl\fR. .IP "Pointer to an \s-1SSL_SESSION\s0" 4 .IX Item "Pointer to an SSL_SESSION" The return value points to the data of an \s-1SSL\s0 session. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_free\fR\|(3), \&\fBSSL_clear\fR\|(3), \&\fBSSL_SESSION_free\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2021 The OpenSSL Project Authors.

They will typically be called after a failed \fBBIO_read_ex()\fR or \fBBIO_write_ex()\fR call. .PP \&\fBBIO_should_retry()\fR is true if the call that produced this condition should then be retried at a later time. .PP If \fBBIO_should_retry()\fR is false then the cause is an error condition. .PP \&\fBBIO_should_read()\fR is true if the cause of the condition is that the \s-1BIO\s0 has insufficient data to return. Check for readability and/or retry the last operation. .PP \&\fBBIO_should_write()\fR is true if the cause of the condition is that the \s-1BIO\s0 has pending data to write. Check for writability and/or retry the last operation. .PP \&\fBBIO_should_io_special()\fR is true if some \*(L"special\*(R" condition, that is a reason other than reading or writing is the cause of the condition. .PP \&\fBBIO_retry_type()\fR returns a mask of the cause of a retry condition consisting of the values \fB\s-1BIO_FLAGS_READ\s0\fR, \fB\s-1BIO_FLAGS_WRITE\s0\fR, \&\fB\s-1BIO_FLAGS_IO_SPECIAL\s0\fR though current \s-1BIO\s0 types will only set one of these. .PP \&\fBBIO_get_retry_BIO()\fR determines the precise reason for the special condition, it returns the \s-1BIO\s0 that caused this condition and if \&\fBreason\fR is not \s-1NULL\s0 it contains the reason code. The meaning of the reason code and the action that should be taken depends on the type of \s-1BIO\s0 that resulted in this condition. .PP \&\fBBIO_get_retry_reason()\fR returns the reason for a special condition if passed the relevant \s-1BIO,\s0 for example as returned by \fBBIO_get_retry_BIO()\fR. .PP \&\fBBIO_set_retry_reason()\fR sets the retry reason for a special condition for a given \&\s-1BIO.\s0 This would usually only be called by \s-1BIO\s0 implementations. .SH "NOTES" .IX Header "NOTES" \&\fBBIO_should_read()\fR, \fBBIO_should_write()\fR, \fBBIO_should_io_special()\fR, \&\fBBIO_retry_type()\fR, and \fBBIO_should_retry()\fR, are implemented as macros. .PP If \fBBIO_should_retry()\fR returns false then the precise \*(L"error condition\*(R" depends on the \s-1BIO\s0 type that caused it and the return code of the \s-1BIO\s0 operation. For example if a call to \fBBIO_read_ex()\fR on a socket \s-1BIO\s0 returns 0 and \fBBIO_should_retry()\fR is false then the cause will be that the connection closed. A similar condition on a file \s-1BIO\s0 will mean that it has reached \s-1EOF.\s0 Some \s-1BIO\s0 types may place additional information on the error queue. For more details see the individual \s-1BIO\s0 type manual pages. .PP If the underlying I/O structure is in a blocking mode almost all current \&\s-1BIO\s0 types will not request a retry, because the underlying I/O calls will not. If the application knows that the \s-1BIO\s0 type will never signal a retry then it need not call \fBBIO_should_retry()\fR after a failed \&\s-1BIO I/O\s0 call. This is typically done with file BIOs. .PP \&\s-1SSL\s0 BIOs are the only current exception to this rule: they can request a retry even if the underlying I/O structure is blocking, if a handshake occurs during a call to \fBBIO_read()\fR. An application can retry the failed call immediately or avoid this situation by setting \s-1SSL_MODE_AUTO_RETRY\s0 on the underlying \s-1SSL\s0 structure. .PP While an application may retry a failed non blocking call immediately this is likely to be very inefficient because the call will fail repeatedly until data can be processed or is available. An application will normally wait until the necessary condition is satisfied. How this is done depends on the underlying I/O structure. .PP For example if the cause is ultimately a socket and \fBBIO_should_read()\fR is true then a call to \fBselect()\fR may be made to wait until data is available and then retry the \s-1BIO\s0 operation. By combining the retry conditions of several non blocking BIOs in a single \fBselect()\fR call it is possible to service several BIOs in a single thread, though the performance may be poor if \s-1SSL\s0 BIOs are present because long delays can occur during the initial handshake process. .PP It is possible for a \s-1BIO\s0 to block indefinitely if the underlying I/O structure cannot process or return any data. This depends on the behaviour of the platforms I/O functions. This is often not desirable: one solution is to use non blocking I/O and use a timeout on the \fBselect()\fR (or equivalent) call. .SH "BUGS" .IX Header "BUGS" The OpenSSL \s-1ASN1\s0 functions cannot gracefully deal with non blocking I/O: that is they cannot retry after a partial read or write. This is usually worked around by only passing the relevant data to \s-1ASN1\s0 functions when the entire structure can be read or written. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBBIO_should_read()\fR, \fBBIO_should_write()\fR, \fBBIO_should_io_special()\fR, and \&\fBBIO_should_retry()\fR return either 1 or 0 based on the actual conditions of the \fB\s-1BIO\s0\fR. .PP \&\fBBIO_retry_type()\fR returns a flag combination presenting the cause of a retry condition or false if there is no retry condition. .PP \&\fBBIO_get_retry_BIO()\fR returns a valid \fB\s-1BIO\s0\fR structure. .PP \&\fBBIO_get_retry_reason()\fR returns the reason for a special condition. .SH "SEE ALSO" .IX Header "SEE ALSO" bio .SH "HISTORY" .IX Header "HISTORY" The \fBBIO_get_retry_reason()\fR and \fBBIO_set_retry_reason()\fR functions were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2018 The OpenSSL Project Authors.

The reference count for session \fBc\fR is incremented by 1. If a session with the same session id already exists, the old session is removed by calling \&\fBSSL_SESSION_free\fR\|(3). .PP \&\fBSSL_CTX_remove_session()\fR removes the session \fBc\fR from the context \fBctx\fR and marks it as non-resumable. \fBSSL_SESSION_free\fR\|(3) is called once for \fBc\fR. .SH "NOTES" .IX Header "NOTES" When adding a new session to the internal session cache, it is examined whether a session with the same session id already exists. In this case it is assumed that both sessions are identical. If the same session is stored in a different \s-1SSL_SESSION\s0 object, The old session is removed and replaced by the new session. If the session is actually identical (the \s-1SSL_SESSION\s0 object is identical), \fBSSL_CTX_add_session()\fR is a no-op, and the return value is 0. .PP If a server \s-1SSL_CTX\s0 is configured with the \s-1SSL_SESS_CACHE_NO_INTERNAL_STORE\s0 flag then the internal cache will not be populated automatically by new sessions negotiated by the \s-1SSL/TLS\s0 implementation, even though the internal cache will be searched automatically for session-resume requests (the latter can be suppressed by \s-1SSL_SESS_CACHE_NO_INTERNAL_LOOKUP\s0). So the application can use \fBSSL_CTX_add_session()\fR directly to have full control over the sessions that can be resumed if desired. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following values are returned by all functions: .IP "0" 4 The operation failed.

The \s-1SSL\s0 engine inherits the behaviour of \fBrbio\fR. If the \s-1BIO\s0 is nonblocking then the \fBssl\fR object will also have nonblocking behaviour. This function transfers ownership of \fBrbio\fR to \fBssl\fR. It will be automatically freed using \fBBIO_free_all\fR\|(3) when the \fBssl\fR is freed. On calling this function, any existing \fBrbio\fR that was previously set will also be freed via a call to \fBBIO_free_all\fR\|(3) (this includes the case where the \fBrbio\fR is set to the same value as previously). .PP \&\fBSSL_set0_wbio()\fR works in the same as \fBSSL_set0_rbio()\fR except that it connects the \s-1BIO\s0 \fBwbio\fR for the write operations of the \fBssl\fR object.

The signature is specified using the \fBsig\fR and \&\fBsiglen\fR parameters. If \fBrout\fR is \fB\s-1NULL\s0\fR then the maximum size of the output buffer is written to the \fBroutlen\fR parameter. If \fBrout\fR is not \fB\s-1NULL\s0\fR then before the call the \fBroutlen\fR parameter should contain the length of the \&\fBrout\fR buffer, if the call is successful recovered data is written to \&\fBrout\fR and the amount of data written to \fBroutlen\fR. .SH "NOTES" .IX Header "NOTES" Normally an application is only interested in whether a signature verification operation is successful in those cases the \fBEVP_verify()\fR function should be used. .PP Sometimes however it is useful to obtain the data originally signed using a signing operation. Only certain public key algorithms can recover a signature in this way (for example \s-1RSA\s0 in \s-1PKCS\s0 padding mode). .PP After the call to \fBEVP_PKEY_verify_recover_init()\fR algorithm specific control operations can be performed to set any appropriate parameters for the operation. .PP The function \fBEVP_PKEY_verify_recover()\fR can be called more than once on the same context if several operations are performed using the same parameters. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_PKEY_verify_recover_init()\fR and \fBEVP_PKEY_verify_recover()\fR return 1 for success and 0 or a negative value for failure.

This can be used by custom BIOs for storing implementation specific information. .PP The \fBBIO_set_init()\fR function sets the value of the \s-1BIO\s0's \*(L"init\*(R" flag to indicate whether initialisation has been completed for this \s-1BIO\s0 or not. A nonzero value indicates that initialisation is complete, whilst zero indicates that it is not. Often initialisation will complete during initial construction of the \s-1BIO.\s0 For some BIOs however, initialisation may not complete until after additional steps have occurred (for example through calling custom ctrls).

It sends the close_notify shutdown alert to the peer. .SH "NOTES" .IX Header "NOTES" \&\fBSSL_shutdown()\fR tries to send the close_notify shutdown alert to the peer. Whether the operation succeeds or not, the \s-1SSL_SENT_SHUTDOWN\s0 flag is set and a currently open session is considered closed and good and will be kept in the session cache for further reuse. .PP Note that \fBSSL_shutdown()\fR must not be called if a previous fatal error has occurred on a connection i.e. if \fBSSL_get_error()\fR has returned \s-1SSL_ERROR_SYSCALL\s0 or \s-1SSL_ERROR_SSL.\s0 .PP The shutdown procedure consists of two steps: sending of the close_notify shutdown alert, and reception of the peer's close_notify shutdown alert. The order of those two steps depends on the application. .PP It is acceptable for an application to only send its shutdown alert and then close the underlying connection without waiting for the peer's response. This way resources can be saved, as the process can already terminate or serve another connection. This should only be done when it is known that the other side will not send more data, otherwise there is a risk of a truncation attack. .PP When a client only writes and never reads from the connection, and the server has sent a session ticket to establish a session, the client might not be able to resume the session because it did not received and process the session ticket from the server. In case the application wants to be able to resume the session, it is recommended to do a complete shutdown procedure (bidirectional close_notify alerts). .PP When the underlying connection shall be used for more communications, the complete shutdown procedure must be performed, so that the peers stay synchronized. .PP \&\fBSSL_shutdown()\fR only closes the write direction. It is not possible to call \fBSSL_write()\fR after calling \fBSSL_shutdown()\fR. The read direction is closed by the peer. .SS "First to close the connection" .IX Subsection "First to close the connection" When the application is the first party to send the close_notify alert, \fBSSL_shutdown()\fR will only send the alert and then set the \&\s-1SSL_SENT_SHUTDOWN\s0 flag (so that the session is considered good and will be kept in the cache). If successful, \fBSSL_shutdown()\fR will return 0. .PP If a unidirectional shutdown is enough (the underlying connection shall be closed anyway), this first successful call to \fBSSL_shutdown()\fR is sufficient. .PP In order to complete the bidirectional shutdown handshake, the peer needs to send back a close_notify alert. The \s-1SSL_RECEIVED_SHUTDOWN\s0 flag will be set after receiving and processing it. .PP The peer is still allowed to send data after receiving the close_notify event. When it is done sending data, it will send the close_notify alert. \&\fBSSL_read()\fR should be called until all data is received. \&\fBSSL_read()\fR will indicate the end of the peer data by returning <= 0 and \fBSSL_get_error()\fR returning \s-1SSL_ERROR_ZERO_RETURN.\s0 .SS "Peer closes the connection" .IX Subsection "Peer closes the connection" If the peer already sent the close_notify alert \fBand\fR it was already processed implicitly inside another function (\fBSSL_read\fR\|(3)), the \s-1SSL_RECEIVED_SHUTDOWN\s0 flag is set. \&\fBSSL_read()\fR will return <= 0 in that case, and \fBSSL_get_error()\fR will return \&\s-1SSL_ERROR_ZERO_RETURN.\s0 \&\fBSSL_shutdown()\fR will send the close_notify alert, set the \s-1SSL_SENT_SHUTDOWN\s0 flag. If successful, \fBSSL_shutdown()\fR will return 1. .PP Whether \s-1SSL_RECEIVED_SHUTDOWN\s0 is already set can be checked using the \&\fBSSL_get_shutdown()\fR (see also \fBSSL_set_shutdown\fR\|(3) call. .SH "NOTES" .IX Header "NOTES" The behaviour of \fBSSL_shutdown()\fR additionally depends on the underlying \s-1BIO.\s0 If the underlying \s-1BIO\s0 is \fBblocking\fR, \fBSSL_shutdown()\fR will only return once the handshake step has been finished or an error occurred. .PP If the underlying \s-1BIO\s0 is \fBnonblocking\fR, \fBSSL_shutdown()\fR will also return when the underlying \s-1BIO\s0 could not satisfy the needs of \fBSSL_shutdown()\fR to continue the handshake. In this case a call to \fBSSL_get_error()\fR with the return value of \fBSSL_shutdown()\fR will yield \fB\s-1SSL_ERROR_WANT_READ\s0\fR or \&\fB\s-1SSL_ERROR_WANT_WRITE\s0\fR. The calling process then must repeat the call after taking appropriate action to satisfy the needs of \fBSSL_shutdown()\fR. The action depends on the underlying \s-1BIO.\s0 When using a nonblocking socket, nothing is to be done, but \fBselect()\fR can be used to check for the required condition. When using a buffering \s-1BIO,\s0 like a \s-1BIO\s0 pair, data must be written into or retrieved out of the \s-1BIO\s0 before being able to continue. .PP After \fBSSL_shutdown()\fR returned 0, it is possible to call \fBSSL_shutdown()\fR again to wait for the peer's close_notify alert. \&\fBSSL_shutdown()\fR will return 1 in that case. However, it is recommended to wait for it using \fBSSL_read()\fR instead. .PP \&\fBSSL_shutdown()\fR can be modified to only set the connection to \*(L"shutdown\*(R" state but not actually send the close_notify alert messages, see \fBSSL_CTX_set_quiet_shutdown\fR\|(3). When \*(L"quiet shutdown\*(R" is enabled, \fBSSL_shutdown()\fR will always succeed and return 1. Note that this is not standard compliant behaviour. It should only be done when the peer has a way to make sure all data has been received and doesn't wait for the close_notify alert message, otherwise an unexpected \s-1EOF\s0 will be reported. .PP There are implementations that do not send the required close_notify alert. If there is a need to communicate with such an implementation, and it's clear that all data has been received, do not wait for the peer's close_notify alert. Waiting for the close_notify alert when the peer just closes the connection will result in an error being generated. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following return values can occur: .IP "0" 4 The shutdown is not yet finished: the close_notify was sent but the peer did not send it back yet. Call \fBSSL_read()\fR to do a bidirectional shutdown. .Sp Unlike most other function, returning 0 does not indicate an error. \&\fBSSL_get_error\fR\|(3) should not get called, it may misleadingly indicate an error even though no error occurred. .IP "1" 4 .IX Item "1" The shutdown was successfully completed. The close_notify alert was sent and the peer's close_notify alert was received. .IP "<0" 4 .IX Item "<0" The shutdown was not successful. Call \fBSSL_get_error\fR\|(3) with the return value \fBret\fR to find out the reason.

In particular when the source/sink is nonblocking or of a certain type it may merely be an indication that no data is currently available and that the application should retry the operation later. .PP One technique sometimes used with blocking sockets is to use a system call (such as \fBselect()\fR, \fBpoll()\fR or equivalent) to determine when data is available and then call \fBread()\fR to read the data. The equivalent with BIOs (that is call \&\fBselect()\fR on the underlying I/O structure and then call \fBBIO_read()\fR to read the data) should \fBnot\fR be used because a single call to \fBBIO_read()\fR can cause several reads (and writes in the case of \s-1SSL\s0 BIOs) on the underlying I/O structure and may block as a result. Instead \fBselect()\fR (or equivalent) should be combined with non blocking I/O so successive reads will request a retry instead of blocking. .PP See \fBBIO_should_retry\fR\|(3) for details of how to determine the cause of a retry and other I/O issues. .PP If the \fBBIO_gets()\fR function is not supported by a \s-1BIO\s0 then it possible to work around this by adding a buffering \s-1BIO\s0 \fBBIO_f_buffer\fR\|(3) to the chain. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBBIO_should_retry\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fBBIO_gets()\fR on 1.1.0 and older when called on \fBBIO_fd()\fR based \s-1BIO\s0 does not keep the '\en' at the end of the line in the buffer. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

The array consist of all NIDs of groups in preference order. For a \s-1TLS\s0 client the groups are used directly in the supported groups extension. For a \s-1TLS\s0 server the groups are used to determine the set of shared groups. .PP \&\fBSSL_CTX_set1_groups_list()\fR sets the supported groups for \fBctx\fR to string \fBlist\fR.

It returns the total number of supported groups. The \fBgroups\fR parameter can be \fB\s-1NULL\s0\fR to simply return the number of groups for memory allocation purposes. The \&\fBgroups\fR array is in the form of a set of group NIDs in preference order. It can return zero if the client did not send a supported groups extension. .PP \&\fBSSL_get_shared_group()\fR returns shared group \fBn\fR for a server-side \&\s-1SSL\s0 \fBssl\fR. If \fBn\fR is \-1 then the total number of shared groups is returned, which may be zero. Other than for diagnostic purposes, most applications will only be interested in the first shared group so \fBn\fR is normally set to zero. If the value \fBn\fR is out of range, NID_undef is returned. .PP All these functions are implemented as macros. .PP The curve functions are synonyms for the equivalently named group functions and are identical in every respect. They exist because, prior to \s-1TLS1.3,\s0 there was only the concept of supported curves. In \s-1TLS1.3\s0 this was renamed to supported groups, and extended to include Diffie Hellman groups. The group functions should be used in preference. .SH "NOTES" .IX Header "NOTES" If an application wishes to make use of several of these functions for configuration purposes either on a command line or in a file it should consider using the \s-1SSL_CONF\s0 interface instead of manually parsing options. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set1_groups()\fR, \fBSSL_CTX_set1_groups_list()\fR, \fBSSL_set1_groups()\fR and \&\fBSSL_set1_groups_list()\fR, return 1 for success and 0 for failure. .PP \&\fBSSL_get1_groups()\fR returns the number of groups, which may be zero. .PP \&\fBSSL_get_shared_group()\fR returns the \s-1NID\s0 of shared group \fBn\fR or NID_undef if there is no shared group \fBn\fR; or the total number of shared groups if \fBn\fR is \-1. .PP When called on a client \fBssl\fR, \fBSSL_get_shared_group()\fR has no meaning and returns \-1. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CTX_add_extra_chain_cert\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The curve functions were added in OpenSSL 1.0.2.

If \fB\s-1ASN1_STRFLGS_ESC_2253\s0\fR is set the characters determined by \s-1RFC2253\s0 are escaped. If \fB\s-1ASN1_STRFLGS_ESC_CTRL\s0\fR is set control characters are escaped.

If it is 32 bits then \&\*(L"\eWXXXXXXXX\*(R" is used using eight characters of its hex representation. These forms will only be used if \s-1UTF8\s0 conversion is not set (see below). .PP Printable characters are normally escaped using the backslash '\e' character. If \&\fB\s-1ASN1_STRFLGS_ESC_QUOTE\s0\fR is set then the whole string is instead surrounded by double quote characters: this is arguably more readable than the backslash notation.

The \s-1TLS/SSL\s0 standard does not give any maximum size of the certificate chain. The OpenSSL library handles incoming data by a dynamically allocated buffer. In order to prevent this buffer from growing without bounds due to data received from a faulty or malicious peer, a maximum size for the certificate chain is set. .PP The default value for the maximum certificate chain size is 100kB (30kB on the 16\-bit \s-1DOS\s0 platform). This should be sufficient for usual certificate chains (OpenSSL's default maximum chain length is 10, see \&\fBSSL_CTX_set_verify\fR\|(3), and certificates without special extensions have a typical size of 1\-2kB). .PP For special applications it can be necessary to extend the maximum certificate chain size allowed to be sent by the peer, see e.g. the work on \&\*(L"Internet X.509 Public Key Infrastructure Proxy Certificate Profile\*(R" and \*(L"\s-1TLS\s0 Delegation Protocol\*(R" at http://www.ietf.org/ and http://www.globus.org/ . .PP Under normal conditions it should never be necessary to set a value smaller than the default, as the buffer is handled dynamically and only uses the memory actually required by the data sent by the peer. .PP If the maximum certificate chain size allowed is exceeded, the handshake will fail with a \s-1SSL_R_EXCESSIVE_MESSAGE_SIZE\s0 error. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set_max_cert_list()\fR and \fBSSL_set_max_cert_list()\fR return the previously set value. .PP \&\fBSSL_CTX_get_max_cert_list()\fR and \fBSSL_get_max_cert_list()\fR return the currently set value. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_new\fR\|(3), \&\fBSSL_CTX_set_verify\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2001\-2020 The OpenSSL Project Authors.

Currently, OpenSSL supports the pthread and Windows APIs. OpenSSL can also be built without any multi-threading support, for example on platforms that don't provide any threading support or that provide a threading \s-1API\s0 that is not yet supported by OpenSSL. .PP The following multi-threading function are provided: .IP "\(bu" 2 \&\fBCRYPTO_THREAD_run_once()\fR can be used to perform one-time initialization. The \fBonce\fR argument must be a pointer to a static object of type \&\fB\s-1CRYPTO_ONCE\s0\fR that was statically initialized to the value \&\fB\s-1CRYPTO_ONCE_STATIC_INIT\s0\fR. The \fBinit\fR argument is a pointer to a function that performs the desired exactly once initialization. In particular, this can be used to allocate locks in a thread-safe manner, which can then be used with the locking functions below. .IP "\(bu" 2 \&\fBCRYPTO_THREAD_lock_new()\fR allocates, initializes and returns a new read/write lock. .IP "\(bu" 2 \&\fBCRYPTO_THREAD_read_lock()\fR locks the provided \fBlock\fR for reading. .IP "\(bu" 2 \&\fBCRYPTO_THREAD_write_lock()\fR locks the provided \fBlock\fR for writing. .IP "\(bu" 2 \&\fBCRYPTO_THREAD_unlock()\fR unlocks the previously locked \fBlock\fR. .IP "\(bu" 2 \&\fBCRYPTO_THREAD_lock_free()\fR frees the provided \fBlock\fR. .IP "\(bu" 2 \&\fBCRYPTO_atomic_add()\fR atomically adds \fBamount\fR to \fBval\fR and returns the result of the operation in \fBret\fR. \fBlock\fR will be locked, unless atomic operations are supported on the specific platform. Because of this, if a variable is modified by \fBCRYPTO_atomic_add()\fR then \fBCRYPTO_atomic_add()\fR must be the only way that the variable is modified. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBCRYPTO_THREAD_run_once()\fR returns 1 on success, or 0 on error. .PP \&\fBCRYPTO_THREAD_lock_new()\fR returns the allocated lock, or \s-1NULL\s0 on error. .PP \&\fBCRYPTO_THREAD_lock_free()\fR returns no value. .PP The other functions return 1 on success, or 0 on error. .SH "NOTES" .IX Header "NOTES" On Windows platforms the CRYPTO_THREAD_* types and functions in the openssl/crypto.h header are dependent on some of the types customarily made available by including windows.h. The application developer is likely to require control over when the latter is included, commonly as one of the first included headers. Therefore, it is defined as an application developer's responsibility to include windows.h prior to crypto.h where use of CRYPTO_THREAD_* types and functions is required. .SH "EXAMPLES" .IX Header "EXAMPLES" This example safely initializes and uses a lock. .PP .Vb 4 \& #ifdef _WIN32 \& # include <windows.h> \& #endif \& #include <openssl/crypto.h> \& \& static CRYPTO_ONCE once = CRYPTO_ONCE_STATIC_INIT; \& static CRYPTO_RWLOCK *lock; \& \& static void myinit(void) \& { \& lock = CRYPTO_THREAD_lock_new(); \& } \& \& static int mylock(void) \& { \& if (!CRYPTO_THREAD_run_once(&once, void init) || lock == NULL) \& return 0; \& return CRYPTO_THREAD_write_lock(lock); \& } \& \& static int myunlock(void) \& { \& return CRYPTO_THREAD_unlock(lock); \& } \& \& int serialized(void) \& { \& int ret = 0; \& \& if (mylock()) { \& /* Your code here, do not return without releasing the lock! */ \& ret = ... ; \& } \& myunlock(); \& return ret; \& } .Ve .PP Finalization of locks is an advanced topic, not covered in this example.

For example if multiple signers or non default digest algorithms are needed. New attributes can also be added using the returned CMS_SignerInfo structure and the \s-1CMS\s0 attribute utility functions or the \&\s-1CMS\s0 signed receipt request functions. .PP Any of the following flags (ored together) can be passed in the \fBflags\fR parameter. .PP If \fB\s-1CMS_REUSE_DIGEST\s0\fR is set then an attempt is made to copy the content digest value from the CMS_ContentInfo structure: to add a signer to an existing structure. An error occurs if a matching digest value cannot be found to copy. The returned CMS_ContentInfo structure will be valid and finalized when this flag is set. .PP If \fB\s-1CMS_PARTIAL\s0\fR is set in addition to \fB\s-1CMS_REUSE_DIGEST\s0\fR then the CMS_SignerInfo structure will not be finalized so additional attributes can be added. In this case an explicit call to \fBCMS_SignerInfo_sign()\fR is needed to finalize it. .PP If \fB\s-1CMS_NOCERTS\s0\fR is set the signer's certificate will not be included in the CMS_ContentInfo structure, the signer's certificate must still be supplied in the \fBsigncert\fR parameter though. This can reduce the size of the signature if the signers certificate can be obtained by other means: for example a previously signed message. .PP The SignedData structure includes several \s-1CMS\s0 signedAttributes including the signing time, the \s-1CMS\s0 content type and the supported list of ciphers in an SMIMECapabilities attribute. If \fB\s-1CMS_NOATTR\s0\fR is set then no signedAttributes will be used. If \fB\s-1CMS_NOSMIMECAP\s0\fR is set then just the SMIMECapabilities are omitted. .PP OpenSSL will by default identify signing certificates using issuer name and serial number. If \fB\s-1CMS_USE_KEYID\s0\fR is set it will use the subject key identifier value instead. An error occurs if the signing certificate does not have a subject key identifier extension. .PP If present the SMIMECapabilities attribute indicates support for the following algorithms in preference order: 256 bit \s-1AES,\s0 Gost R3411\-94, Gost 28147\-89, 192 bit \s-1AES, 128\s0 bit \s-1AES,\s0 triple \s-1DES, 128\s0 bit \s-1RC2, 64\s0 bit \s-1RC2, DES\s0 and 40 bit \s-1RC2.\s0 If any of these algorithms is not available then it will not be included: for example the \s-1GOST\s0 algorithms will not be included if the \s-1GOST ENGINE\s0 is not loaded. .PP \&\fBCMS_add1_signer()\fR returns an internal pointer to the CMS_SignerInfo structure just added, this can be used to set additional attributes before it is finalized. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBCMS_add1_signer()\fR returns an internal pointer to the CMS_SignerInfo structure just added or \s-1NULL\s0 if an error occurs. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBERR_get_error\fR\|(3), \fBCMS_sign\fR\|(3), \&\fBCMS_final\fR\|(3), .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2014\-2016 The OpenSSL Project Authors.

On success \fBSSL_read_ex()\fR will store the number of bytes actually read in \fB*readbytes\fR. .PP \&\fBSSL_peek_ex()\fR and \fBSSL_peek()\fR are identical to \fBSSL_read_ex()\fR and \fBSSL_read()\fR respectively except no bytes are actually removed from the underlying \s-1BIO\s0 during the read, so that a subsequent call to \fBSSL_read_ex()\fR or \fBSSL_read()\fR will yield at least the same bytes. .SH "NOTES" .IX Header "NOTES" In the paragraphs below a \*(L"read function\*(R" is defined as one of \fBSSL_read_ex()\fR, \&\fBSSL_read()\fR, \fBSSL_peek_ex()\fR or \fBSSL_peek()\fR. .PP If necessary, a read function will negotiate a \s-1TLS/SSL\s0 session, if not already explicitly performed by \fBSSL_connect\fR\|(3) or \fBSSL_accept\fR\|(3). If the peer requests a re-negotiation, it will be performed transparently during the read function operation. The behaviour of the read functions depends on the underlying \s-1BIO.\s0 .PP For the transparent negotiation to succeed, the \fBssl\fR must have been initialized to client or server mode. This is being done by calling \&\fBSSL_set_connect_state\fR\|(3) or \fBSSL_set_accept_state()\fR before the first invocation of a read function. .PP The read functions work based on the \s-1SSL/TLS\s0 records. The data are received in records (with a maximum record size of 16kB). Only when a record has been completely received, can it be processed (decryption and check of integrity). Therefore, data that was not retrieved at the last read call can still be buffered inside the \s-1SSL\s0 layer and will be retrieved on the next read call. If \fBnum\fR is higher than the number of bytes buffered then the read functions will return with the bytes buffered. If no more bytes are in the buffer, the read functions will trigger the processing of the next record. Only when the record has been received and processed completely will the read functions return reporting success. At most the contents of one record will be returned. As the size of an \s-1SSL/TLS\s0 record may exceed the maximum packet size of the underlying transport (e.g. \s-1TCP\s0), it may be necessary to read several packets from the transport layer before the record is complete and the read call can succeed. .PP If \fB\s-1SSL_MODE_AUTO_RETRY\s0\fR has been switched off and a non-application data record has been processed, the read function can return and set the error to \&\fB\s-1SSL_ERROR_WANT_READ\s0\fR. In this case there might still be unprocessed data available in the \fB\s-1BIO\s0\fR. If read ahead was set using \fBSSL_CTX_set_read_ahead\fR\|(3), there might also still be unprocessed data available in the \fB\s-1SSL\s0\fR. This behaviour can be controlled using the \fBSSL_CTX_set_mode\fR\|(3) call. .PP If the underlying \s-1BIO\s0 is \fBblocking\fR, a read function will only return once the read operation has been finished or an error occurred, except when a non-application data record has been processed and \fB\s-1SSL_MODE_AUTO_RETRY\s0\fR is not set. Note that if \fB\s-1SSL_MODE_AUTO_RETRY\s0\fR is set and only non-application data is available the call will hang. .PP If the underlying \s-1BIO\s0 is \fBnonblocking\fR, a read function will also return when the underlying \s-1BIO\s0 could not satisfy the needs of the function to continue the operation. In this case a call to \fBSSL_get_error\fR\|(3) with the return value of the read function will yield \fB\s-1SSL_ERROR_WANT_READ\s0\fR or \&\fB\s-1SSL_ERROR_WANT_WRITE\s0\fR. As at any time it's possible that non-application data needs to be sent, a read function can also cause write operations. The calling process then must repeat the call after taking appropriate action to satisfy the needs of the read function. The action depends on the underlying \s-1BIO.\s0 When using a nonblocking socket, nothing is to be done, but \fBselect()\fR can be used to check for the required condition. When using a buffering \s-1BIO,\s0 like a \s-1BIO\s0 pair, data must be written into or retrieved out of the \s-1BIO\s0 before being able to continue. .PP \&\fBSSL_pending\fR\|(3) can be used to find out whether there are buffered bytes available for immediate retrieval. In this case the read function can be called without blocking or actually receiving new data from the underlying socket. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_read_ex()\fR and \fBSSL_peek_ex()\fR will return 1 for success or 0 for failure. Success means that 1 or more application data bytes have been read from the \s-1SSL\s0 connection. Failure means that no bytes could be read from the \s-1SSL\s0 connection. Failures can be retryable (e.g. we are waiting for more bytes to be delivered by the network) or non-retryable (e.g. a fatal network error). In the event of a failure call \fBSSL_get_error\fR\|(3) to find out the reason which indicates whether the call is retryable or not. .PP For \fBSSL_read()\fR and \fBSSL_peek()\fR the following return values can occur: .IP "> 0" 4 .IX Item "> 0" The read operation was successful. The return value is the number of bytes actually read from the \s-1TLS/SSL\s0 connection. .IP "<= 0" 4 .IX Item "<= 0" The read operation was not successful, because either the connection was closed, an error occurred or action must be taken by the calling process. Call \fBSSL_get_error\fR\|(3) with the return value \fBret\fR to find out the reason. .Sp Old documentation indicated a difference between 0 and \-1, and that \-1 was retryable.

This function can be called several times on the same \fIctx\fR to include additional data. .PP \&\fBEVP_SignFinal()\fR signs the data in \fIctx\fR using the private key \fIpkey\fR and places the signature in \fIsig\fR. \fIsig\fR must be at least \f(CW\*(C`EVP_PKEY_size(pkey)\*(C'\fR bytes in size. \fIs\fR is an \s-1OUT\s0 parameter, and not used as an \s-1IN\s0 parameter. The number of bytes of data written (i.e. the length of the signature) will be written to the integer at \fIs\fR, at most \f(CW\*(C`EVP_PKEY_size(pkey)\*(C'\fR bytes will be written. .PP \&\fBEVP_SignInit()\fR initializes a signing context \fIctx\fR to use the default implementation of digest \fItype\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_SignInit_ex()\fR, \fBEVP_SignUpdate()\fR and \fBEVP_SignFinal()\fR return 1 for success and 0 for failure. .PP The error codes can be obtained by \fBERR_get_error\fR\|(3). .SH "NOTES" .IX Header "NOTES" The \fB\s-1EVP\s0\fR interface to digital signatures should almost always be used in preference to the low-level interfaces. This is because the code then becomes transparent to the algorithm used and much more flexible. .PP When signing with \s-1DSA\s0 private keys the random number generator must be seeded. If the automatic seeding or reseeding of the OpenSSL \s-1CSPRNG\s0 fails due to external circumstances (see \s-1\fBRAND\s0\fR\|(7)), the operation will fail. This requirement does not hold for \s-1RSA\s0 signatures. .PP The call to \fBEVP_SignFinal()\fR internally finalizes a copy of the digest context. This means that calls to \fBEVP_SignUpdate()\fR and \fBEVP_SignFinal()\fR can be called later to digest and sign additional data. .PP Since only a copy of the digest context is ever finalized the context must be cleaned up after use by calling \fBEVP_MD_CTX_free()\fR or a memory leak will occur. .SH "BUGS" .IX Header "BUGS" Older versions of this documentation wrongly stated that calls to \&\fBEVP_SignUpdate()\fR could not be made after calling \fBEVP_SignFinal()\fR. .PP Since the private key is passed in the call to \fBEVP_SignFinal()\fR any error relating to the private key (for example an unsuitable key and digest combination) will not be indicated until after potentially large amounts of data have been passed through \fBEVP_SignUpdate()\fR. .PP It is not possible to change the signing parameters using these function. .PP The previous two bugs are fixed in the newer EVP_SignDigest*() function. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_PKEY_size\fR\|(3), \fBEVP_PKEY_bits\fR\|(3), \fBEVP_PKEY_security_bits\fR\|(3), \&\fBEVP_VerifyInit\fR\|(3), \&\fBEVP_DigestInit\fR\|(3), \&\fBevp\fR\|(7), \s-1\fBHMAC\s0\fR\|(3), \s-1\fBMD2\s0\fR\|(3), \&\s-1\fBMD5\s0\fR\|(3), \s-1\fBMDC2\s0\fR\|(3), \s-1\fBRIPEMD160\s0\fR\|(3), \&\s-1\fBSHA1\s0\fR\|(3), \fBdgst\fR\|(1) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2020 The OpenSSL Project Authors.

If \fBmd\fR is \s-1NULL,\s0 the digest is placed in a static array. The size of the output is placed in \fBmd_len\fR, unless it is \fB\s-1NULL\s0\fR.

It also contains a public key (\fBpub_key\fR) and (optionally) a private key (\fBpriv_key\fR). .PP The \fBp\fR, \fBq\fR and \fBg\fR parameters can be obtained by calling \fBDSA_get0_pqg()\fR. If the parameters have not yet been set then \fB*p\fR, \fB*q\fR and \fB*g\fR will be set to \s-1NULL.\s0 Otherwise they are set to pointers to their respective values. These point directly to the internal representations of the values and therefore should not be freed directly. .PP The \fBp\fR, \fBq\fR and \fBg\fR values can be set by calling \fBDSA_set0_pqg()\fR and passing the new values for \fBp\fR, \fBq\fR and \fBg\fR as parameters to the function. Calling this function transfers the memory management of the values to the \s-1DSA\s0 object, and therefore the values that have been passed in should not be freed directly after this function has been called. .PP To get the public and private key values use the \fBDSA_get0_key()\fR function. A pointer to the public key will be stored in \fB*pub_key\fR, and a pointer to the private key will be stored in \fB*priv_key\fR. Either may be \s-1NULL\s0 if they have not been set yet, although if the private key has been set then the public key must be. The values point to the internal representation of the public key and private key values. This memory should not be freed directly. .PP The public and private key values can be set using \fBDSA_set0_key()\fR. The public key must be non-NULL the first time this function is called on a given \s-1DSA\s0 object. The private key may be \s-1NULL.\s0 On subsequent calls, either may be \s-1NULL,\s0 which means the corresponding \s-1DSA\s0 field is left untouched. As for \fBDSA_set0_pqg()\fR this function transfers the memory management of the key values to the \s-1DSA\s0 object, and therefore they should not be freed directly after this function has been called. .PP Any of the values \fBp\fR, \fBq\fR, \fBg\fR, \fBpriv_key\fR, and \fBpub_key\fR can also be retrieved separately by the corresponding function \fBDSA_get0_p()\fR, \fBDSA_get0_q()\fR, \&\fBDSA_get0_g()\fR, \fBDSA_get0_priv_key()\fR, and \fBDSA_get0_pub_key()\fR, respectively. .PP \&\fBDSA_set_flags()\fR sets the flags in the \fBflags\fR parameter on the \s-1DSA\s0 object. Multiple flags can be passed in one go (bitwise ORed together). Any flags that are already set are left set. \fBDSA_test_flags()\fR tests to see whether the flags passed in the \fBflags\fR parameter are currently set in the \s-1DSA\s0 object. Multiple flags can be tested in one go. All flags that are currently set are returned, or zero if none of the flags are set. \fBDSA_clear_flags()\fR clears the specified flags within the \s-1DSA\s0 object. .PP \&\fBDSA_get0_engine()\fR returns a handle to the \s-1ENGINE\s0 that has been set for this \s-1DSA\s0 object, or \s-1NULL\s0 if no such \s-1ENGINE\s0 has been set. .SH "NOTES" .IX Header "NOTES" Values retrieved with \fBDSA_get0_key()\fR are owned by the \s-1DSA\s0 object used in the call and may therefore \fInot\fR be passed to \fBDSA_set0_key()\fR. If needed, duplicate the received value using \fBBN_dup()\fR and pass the duplicate. The same applies to \fBDSA_get0_pqg()\fR and \fBDSA_set0_pqg()\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBDSA_set0_pqg()\fR and \fBDSA_set0_key()\fR return 1 on success or 0 on failure. .PP \&\fBDSA_test_flags()\fR returns the current state of the flags in the \s-1DSA\s0 object. .PP \&\fBDSA_get0_engine()\fR returns the \s-1ENGINE\s0 set for the \s-1DSA\s0 object or \s-1NULL\s0 if no \s-1ENGINE\s0 has been set. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBDSA_new\fR\|(3), \fBDSA_new\fR\|(3), \fBDSA_generate_parameters\fR\|(3), \fBDSA_generate_key\fR\|(3), \&\fBDSA_dup_DH\fR\|(3), \fBDSA_do_sign\fR\|(3), \fBDSA_set_method\fR\|(3), \fBDSA_SIG_new\fR\|(3), \&\fBDSA_sign\fR\|(3), \fBDSA_size\fR\|(3), \fBDSA_meth_new\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The functions described here were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2018 The OpenSSL Project Authors.

The new structure inherits the settings of the underlying context \fBctx\fR: connection method, options, verification settings, timeout settings. An \fB\s-1SSL\s0\fR structure is reference counted. Creating an \fB\s-1SSL\s0\fR structure for the first time increments the reference count. Freeing it (using SSL_free) decrements it. When the reference count drops to zero, any memory or resources allocated to the \fB\s-1SSL\s0\fR structure are freed. .PP \&\fBSSL_up_ref()\fR increments the reference count for an existing \fB\s-1SSL\s0\fR structure. .PP The function \fBSSL_dup()\fR creates and returns a new \fB\s-1SSL\s0\fR structure from the same \&\fB\s-1SSL_CTX\s0\fR that was used to create \fIs\fR.

If it wants to set a certificate, a certificate/private key combination must be set using the \fBx509\fR and \fBpkey\fR arguments and \*(L"1\*(R" must be returned. The certificate will be installed into \fBssl\fR, see the \s-1NOTES\s0 and \s-1BUGS\s0 sections. If no certificate should be set, \*(L"0\*(R" has to be returned and no certificate will be sent. A negative return value will suspend the handshake and the handshake function will return immediately. \fBSSL_get_error\fR\|(3) will return \s-1SSL_ERROR_WANT_X509_LOOKUP\s0 to indicate, that the handshake was suspended. The next call to the handshake function will again lead to the call of \fBclient_cert_cb()\fR. It is the job of the \fBclient_cert_cb()\fR to store information about the state of the last call, if required to continue. .SH "NOTES" .IX Header "NOTES" During a handshake (or renegotiation) a server may request a certificate from the client. A client certificate must only be sent, when the server did send the request. .PP When a certificate was set using the \&\fBSSL_CTX_use_certificate\fR\|(3) family of functions, it will be sent to the server. The \s-1TLS\s0 standard requires that only a certificate is sent, if it matches the list of acceptable CAs sent by the server. This constraint is violated by the default behavior of the OpenSSL library. Using the callback function it is possible to implement a proper selection routine or to allow a user interaction to choose the certificate to be sent. .PP If a callback function is defined and no certificate was yet defined for the \&\s-1SSL\s0 object, the callback function will be called. If the callback function returns a certificate, the OpenSSL library will try to load the private key and certificate data into the \s-1SSL\s0 object using the \fBSSL_use_certificate()\fR and \fBSSL_use_private_key()\fR functions. Thus it will permanently install the certificate and key for this \s-1SSL\s0 object. It will not be reset by calling \fBSSL_clear\fR\|(3). If the callback returns no certificate, the OpenSSL library will not send a certificate. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_get_client_cert_cb()\fR returns function pointer of \fBclient_cert_cb()\fR or \&\s-1NULL\s0 if the callback is not set. .SH "BUGS" .IX Header "BUGS" The \fBclient_cert_cb()\fR cannot return a complete certificate chain, it can only return one client certificate. If the chain only has a length of 2, the root \s-1CA\s0 certificate may be omitted according to the \s-1TLS\s0 standard and thus a standard conforming answer can be sent to the server. For a longer chain, the client must send the complete chain (with the option to leave out the root \s-1CA\s0 certificate). This can only be accomplished by either adding the intermediate \s-1CA\s0 certificates into the trusted certificate store for the \s-1SSL_CTX\s0 object (resulting in having to add \&\s-1CA\s0 certificates that otherwise maybe would not be trusted), or by adding the chain certificates using the \&\fBSSL_CTX_add_extra_chain_cert\fR\|(3) function, which is only available for the \s-1SSL_CTX\s0 object as a whole and that therefore probably can only apply for one client certificate, making the concept of the callback function (to allow the choice from several certificates) questionable. .PP Once the \s-1SSL\s0 object has been used in conjunction with the callback function, the certificate will be set for the \s-1SSL\s0 object and will not be cleared even when \fBSSL_clear\fR\|(3) is being called. It is therefore mandatory to destroy the \s-1SSL\s0 object using \fBSSL_free\fR\|(3) and create a new one to return to the previous state. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_CTX_use_certificate\fR\|(3), \&\fBSSL_CTX_add_extra_chain_cert\fR\|(3), \&\fBSSL_get_client_CA_list\fR\|(3), \&\fBSSL_clear\fR\|(3), \fBSSL_free\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2002\-2018 The OpenSSL Project Authors.

The value returned by that \s-1TLS/SSL I/O\s0 function must be passed to \fBSSL_get_error()\fR in parameter \fBret\fR. .PP In addition to \fBssl\fR and \fBret\fR, \fBSSL_get_error()\fR inspects the current thread's OpenSSL error queue. Thus, \fBSSL_get_error()\fR must be used in the same thread that performed the \s-1TLS/SSL I/O\s0 operation, and no other OpenSSL function calls should appear in between. The current thread's error queue must be empty before the \s-1TLS/SSL I/O\s0 operation is attempted, or \fBSSL_get_error()\fR will not work reliably. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following return values can currently occur: .IP "\s-1SSL_ERROR_NONE\s0" 4 .IX Item "SSL_ERROR_NONE" The \s-1TLS/SSL I/O\s0 operation completed. This result code is returned if and only if \fBret > 0\fR. .IP "\s-1SSL_ERROR_ZERO_RETURN\s0" 4 .IX Item "SSL_ERROR_ZERO_RETURN" The \s-1TLS/SSL\s0 peer has closed the connection for writing by sending the close_notify alert. No more data can be read. Note that \fB\s-1SSL_ERROR_ZERO_RETURN\s0\fR does not necessarily indicate that the underlying transport has been closed. .IP "\s-1SSL_ERROR_WANT_READ, SSL_ERROR_WANT_WRITE\s0" 4 .IX Item "SSL_ERROR_WANT_READ, SSL_ERROR_WANT_WRITE" The operation did not complete and can be retried later. .Sp \&\fB\s-1SSL_ERROR_WANT_READ\s0\fR is returned when the last operation was a read operation from a nonblocking \fB\s-1BIO\s0\fR. It means that not enough data was available at this time to complete the operation. If at a later time the underlying \fB\s-1BIO\s0\fR has data available for reading the same function can be called again. .Sp \&\fBSSL_read()\fR and \fBSSL_read_ex()\fR can also set \fB\s-1SSL_ERROR_WANT_READ\s0\fR when there is still unprocessed data available at either the \fB\s-1SSL\s0\fR or the \fB\s-1BIO\s0\fR layer, even for a blocking \fB\s-1BIO\s0\fR. See \fBSSL_read\fR\|(3) for more information. .Sp \&\fB\s-1SSL_ERROR_WANT_WRITE\s0\fR is returned when the last operation was a write to a nonblocking \fB\s-1BIO\s0\fR and it was unable to sent all data to the \fB\s-1BIO\s0\fR. When the \fB\s-1BIO\s0\fR is writable again, the same function can be called again. .Sp Note that the retry may again lead to an \fB\s-1SSL_ERROR_WANT_READ\s0\fR or \&\fB\s-1SSL_ERROR_WANT_WRITE\s0\fR condition. There is no fixed upper limit for the number of iterations that may be necessary until progress becomes visible at application protocol level. .Sp It is safe to call \fBSSL_read()\fR or \fBSSL_read_ex()\fR when more data is available even when the call that set this error was an \fBSSL_write()\fR or \fBSSL_write_ex()\fR. However, if the call was an \fBSSL_write()\fR or \fBSSL_write_ex()\fR, it should be called again to continue sending the application data. .Sp For socket \fB\s-1BIO\s0\fRs (e.g. when \fBSSL_set_fd()\fR was used), \fBselect()\fR or \&\fBpoll()\fR on the underlying socket can be used to find out when the \&\s-1TLS/SSL I/O\s0 function should be retried. .Sp Caveat: Any \s-1TLS/SSL I/O\s0 function can lead to either of \&\fB\s-1SSL_ERROR_WANT_READ\s0\fR and \fB\s-1SSL_ERROR_WANT_WRITE\s0\fR. In particular, \&\fBSSL_read_ex()\fR, \fBSSL_read()\fR, \fBSSL_peek_ex()\fR, or \fBSSL_peek()\fR may want to write data and \fBSSL_write()\fR or \fBSSL_write_ex()\fR may want to read data. This is mainly because \&\s-1TLS/SSL\s0 handshakes may occur at any time during the protocol (initiated by either the client or the server); \fBSSL_read_ex()\fR, \fBSSL_read()\fR, \fBSSL_peek_ex()\fR, \&\fBSSL_peek()\fR, \fBSSL_write_ex()\fR, and \fBSSL_write()\fR will handle any pending handshakes. .IP "\s-1SSL_ERROR_WANT_CONNECT, SSL_ERROR_WANT_ACCEPT\s0" 4 .IX Item "SSL_ERROR_WANT_CONNECT, SSL_ERROR_WANT_ACCEPT" The operation did not complete; the same \s-1TLS/SSL I/O\s0 function should be called again later. The underlying \s-1BIO\s0 was not connected yet to the peer and the call would block in \fBconnect()\fR/\fBaccept()\fR. The \s-1SSL\s0 function should be called again when the connection is established. These messages can only appear with a \fBBIO_s_connect()\fR or \fBBIO_s_accept()\fR \s-1BIO,\s0 respectively. In order to find out, when the connection has been successfully established, on many platforms \fBselect()\fR or \fBpoll()\fR for writing on the socket file descriptor can be used. .IP "\s-1SSL_ERROR_WANT_X509_LOOKUP\s0" 4 .IX Item "SSL_ERROR_WANT_X509_LOOKUP" The operation did not complete because an application callback set by \&\fBSSL_CTX_set_client_cert_cb()\fR has asked to be called again. The \s-1TLS/SSL I/O\s0 function should be called again later. Details depend on the application. .IP "\s-1SSL_ERROR_WANT_ASYNC\s0" 4 .IX Item "SSL_ERROR_WANT_ASYNC" The operation did not complete because an asynchronous engine is still processing data. This will only occur if the mode has been set to \s-1SSL_MODE_ASYNC\s0 using \fBSSL_CTX_set_mode\fR\|(3) or \fBSSL_set_mode\fR\|(3) and an asynchronous capable engine is being used. An application can determine whether the engine has completed its processing using \fBselect()\fR or \fBpoll()\fR on the asynchronous wait file descriptor. This file descriptor is available by calling \&\fBSSL_get_all_async_fds\fR\|(3) or \fBSSL_get_changed_async_fds\fR\|(3). The \s-1TLS/SSL I/O\s0 function should be called again later. The function \fBmust\fR be called from the same thread that the original call was made from. .IP "\s-1SSL_ERROR_WANT_ASYNC_JOB\s0" 4 .IX Item "SSL_ERROR_WANT_ASYNC_JOB" The asynchronous job could not be started because there were no async jobs available in the pool (see \fBASYNC_init_thread\fR\|(3)). This will only occur if the mode has been set to \s-1SSL_MODE_ASYNC\s0 using \fBSSL_CTX_set_mode\fR\|(3) or \&\fBSSL_set_mode\fR\|(3) and a maximum limit has been set on the async job pool through a call to \fBASYNC_init_thread\fR\|(3). The application should retry the operation after a currently executing asynchronous operation for the current thread has completed. .IP "\s-1SSL_ERROR_WANT_CLIENT_HELLO_CB\s0" 4 .IX Item "SSL_ERROR_WANT_CLIENT_HELLO_CB" The operation did not complete because an application callback set by \&\fBSSL_CTX_set_client_hello_cb()\fR has asked to be called again. The \s-1TLS/SSL I/O\s0 function should be called again later. Details depend on the application. .IP "\s-1SSL_ERROR_SYSCALL\s0" 4 .IX Item "SSL_ERROR_SYSCALL" Some non-recoverable, fatal I/O error occurred. The OpenSSL error queue may contain more information on the error. For socket I/O on Unix systems, consult \&\fBerrno\fR for details. If this error occurs then no further I/O operations should be performed on the connection and \fBSSL_shutdown()\fR must not be called. .Sp This value can also be returned for other errors, check the error queue for details. .IP "\s-1SSL_ERROR_SSL\s0" 4 .IX Item "SSL_ERROR_SSL" A non-recoverable, fatal error in the \s-1SSL\s0 library occurred, usually a protocol error. The OpenSSL error queue contains more information on the error. If this error occurs then no further I/O operations should be performed on the connection and \fBSSL_shutdown()\fR must not be called. .SH "BUGS" .IX Header "BUGS" The \fB\s-1SSL_ERROR_SYSCALL\s0\fR with \fBerrno\fR value of 0 indicates unexpected \s-1EOF\s0 from the peer. This will be properly reported as \fB\s-1SSL_ERROR_SSL\s0\fR with reason code \fB\s-1SSL_R_UNEXPECTED_EOF_WHILE_READING\s0\fR in the OpenSSL 3.0 release because it is truly a \s-1TLS\s0 protocol error to terminate the connection without a \fBSSL_shutdown()\fR. .PP The issue is kept unfixed in OpenSSL 1.1.1 releases because many applications which choose to ignore this protocol error depend on the existing way of reporting the error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" The \s-1SSL_ERROR_WANT_ASYNC\s0 error code was added in OpenSSL 1.1.0.

The callback functions are implemented and provided by the caller. Their parameter lists need to match the function prototypes above. .PP Setting the callbacks is allowed only if the \s-1DRBG\s0 has not been initialized yet. Otherwise, the operation will fail. To change the settings for one of the three shared DRBGs it is necessary to call \&\fBRAND_DRBG_uninstantiate()\fR first. .PP The \fBget_entropy\fR() callback is called by the \fBdrbg\fR when it requests fresh random input. It is expected that the callback allocates and fills a random buffer of size \&\fBmin_len\fR <= size <= \fBmax_len\fR (in bytes) which contains at least \fBentropy\fR bits of randomness. The \fBprediction_resistance\fR flag indicates whether the reseeding was triggered by a prediction resistance request. .PP The buffer's address is to be returned in *\fBpout\fR and the number of collected randomness bytes as return value. .PP If the callback fails to acquire at least \fBentropy\fR bits of randomness, it must indicate an error by returning a buffer length of 0. .PP If \fBprediction_resistance\fR was requested and the random source of the \s-1DRBG\s0 does not satisfy the conditions requested by [\s-1NIST SP 800\-90C\s0], then it must also indicate an error by returning a buffer length of 0. See \s-1NOTES\s0 section for more details. .PP The \fBcleanup_entropy\fR() callback is called from the \fBdrbg\fR to clear and free the buffer allocated previously by \fBget_entropy()\fR. The values \fBout\fR and \fBoutlen\fR are the random buffer's address and length, as returned by the \fBget_entropy()\fR callback. .PP The \fBget_nonce\fR() and \fBcleanup_nonce\fR() callbacks are used to obtain a nonce and free it again. A nonce is only required for instantiation (not for reseeding) and only in the case where the \s-1DRBG\s0 uses a derivation function. The callbacks are analogous to \fBget_entropy()\fR and \fBcleanup_entropy()\fR, except for the missing prediction_resistance flag. .PP If the derivation function is disabled, then no nonce is used for instantiation, and the \fBget_nonce\fR() and \fBcleanup_nonce\fR() callbacks can be omitted by setting them to \s-1NULL.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBRAND_DRBG_set_callbacks()\fR return 1 on success, and 0 on failure .SH "NOTES" .IX Header "NOTES" It is important that \fBcleanup_entropy\fR() and \fBcleanup_nonce\fR() clear the buffer contents safely before freeing it, in order not to leave sensitive information about the \s-1DRBG\s0's state in memory. .PP A request for prediction resistance can only be satisfied by pulling fresh entropy from one of the approved entropy sources listed in section 5.5.2 of [\s-1NIST SP 800\-90C\s0]. Since the default implementation of the get_entropy callback does not have access to such an approved entropy source, a request for prediction resistance will always fail. In other words, prediction resistance is currently not supported yet by the \s-1DRBG.\s0 .PP The derivation function is disabled during initialization by calling the \&\fBRAND_DRBG_set()\fR function with the \s-1RAND_DRBG_FLAG_CTR_NO_DF\s0 flag. For more information on the derivation function and when it can be omitted, see [\s-1NIST SP 800\-90A\s0 Rev. 1]. Roughly speaking it can be omitted if the random source has \*(L"full entropy\*(R", i.e., contains 8 bits of entropy per byte. .PP Even if a nonce is required, the \fBget_nonce\fR() and \fBcleanup_nonce\fR() callbacks can be omitted by setting them to \s-1NULL.\s0 In this case the \s-1DRBG\s0 will automatically request an extra amount of entropy (using the \fBget_entropy\fR() and \fBcleanup_entropy\fR() callbacks) which it will utilize for the nonce, following the recommendations of [\s-1NIST SP 800\-90A\s0 Rev. 1], section 8.6.7. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBRAND_DRBG_new\fR\|(3), \&\fBRAND_DRBG_reseed\fR\|(3), \&\s-1\fBRAND_DRBG\s0\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" The \s-1RAND_DRBG\s0 functions were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2017\-2020 The OpenSSL Project Authors.

If the \&\fBsalt\fR is \s-1NULL,\s0 then \fBsaltlen\fR must be 0. The function will not attempt to calculate the length of the \fBsalt\fR because it is not assumed to be \s-1NULL\s0 terminated. .PP \&\fBiter\fR is the iteration count and its value should be greater than or equal to 1. \s-1RFC 2898\s0 suggests an iteration count of at least 1000. Any \&\fBiter\fR less than 1 is treated as a single iteration. .PP \&\fBdigest\fR is the message digest function used in the derivation. Values include any of the EVP_* message digests. \s-1\fBPKCS5_PBKDF2_HMAC_SHA1\s0()\fR calls \&\s-1\fBPKCS5_PBKDF2_HMAC\s0()\fR with \fBEVP_sha1()\fR. .PP The derived key will be written to \fBout\fR. The size of the \fBout\fR buffer is specified via \fBkeylen\fR. .SH "NOTES" .IX Header "NOTES" A typical application of this function is to derive keying material for an encryption algorithm from a password in the \fBpass\fR, a salt in \fBsalt\fR, and an iteration count. .PP Increasing the \fBiter\fR parameter slows down the algorithm which makes it harder for an attacker to perform a brute force attack using a large number of candidate passwords. .PP These functions make no assumption regarding the given password.

Depending on the settings, see \&\fBSSL_CTX_set_session_cache_mode\fR\|(3), the \s-1SSL_SESSION\s0 objects are internally referenced by the \s-1SSL_CTX\s0 and linked into its session cache. \s-1SSL\s0 objects may be using the \s-1SSL_SESSION\s0 object; as a session may be reused, several \s-1SSL\s0 objects may be using one \s-1SSL_SESSION\s0 object at the same time. It is therefore crucial to keep the reference count (usage information) correct and not delete a \s-1SSL_SESSION\s0 object that is still used, as this may lead to program failures due to dangling pointers. These failures may also appear delayed, e.g. when an \s-1SSL_SESSION\s0 object was completely freed as the reference count incorrectly became 0, but it is still referenced in the internal session cache and the cache list is processed during a \&\fBSSL_CTX_flush_sessions\fR\|(3) operation. .PP \&\fBSSL_SESSION_free()\fR must only be called for \s-1SSL_SESSION\s0 objects, for which the reference count was explicitly incremented (e.g. by calling \fBSSL_get1_session()\fR, see \fBSSL_get_session\fR\|(3)) or when the \s-1SSL_SESSION\s0 object was generated outside a \s-1TLS\s0 handshake operation, e.g. by using \fBd2i_SSL_SESSION\fR\|(3).

It is believed to be compatible with RC4[\s-1TM\s0], a proprietary cipher of \s-1RSA\s0 Security Inc. .PP \&\s-1RC4\s0 is a stream cipher with variable key length. Typically, 128 bit (16 byte) keys are used for strong encryption, but shorter insecure key sizes have been widely used due to export restrictions. .PP \&\s-1RC4\s0 consists of a key setup phase and the actual encryption or decryption phase. .PP \&\fBRC4_set_key()\fR sets up the \fB\s-1RC4_KEY\s0\fR \fBkey\fR using the \fBlen\fR bytes long key at \fBdata\fR. .PP \&\s-1\fBRC4\s0()\fR encrypts or decrypts the \fBlen\fR bytes of data at \fBindata\fR using \&\fBkey\fR and places the result at \fBoutdata\fR. Repeated \s-1\fBRC4\s0()\fR calls with the same \fBkey\fR yield a continuous key stream. .PP Since \s-1RC4\s0 is a stream cipher (the input is XORed with a pseudo-random key stream to produce the output), decryption uses the same function calls as encryption. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBRC4_set_key()\fR and \s-1\fBRC4\s0()\fR do not return values. .SH "NOTE" .IX Header "NOTE" Applications should use the higher level functions \&\fBEVP_EncryptInit\fR\|(3) etc. instead of calling these functions directly. .PP It is difficult to securely use stream ciphers.

If not set then 1 is used. .PP The security framework disables or reject parameters inconsistent with the set security level. In the past this was difficult as applications had to set a number of distinct parameters (supported ciphers, supported curves supported signature algorithms) to achieve this end and some cases (\s-1DH\s0 parameter size for example) could not be checked at all. .PP By setting an appropriate security level much of this complexity can be avoided. .PP The bits of security limits affect all relevant parameters including cipher suite encryption algorithms, supported \s-1ECC\s0 curves, supported signature algorithms, \s-1DH\s0 parameter sizes, certificate key sizes and signature algorithms. This limit applies no matter what other custom settings an application has set: so if the cipher suite is set to \fB\s-1ALL\s0\fR then only cipher suites consistent with the security level are permissible. .PP See \s-1SP800\-57\s0 for how the security limits are related to individual algorithms. .PP Some security levels require large key sizes for non-ECC public key algorithms which can severely degrade performance. For example 256 bits of security requires the use of \s-1RSA\s0 keys of at least 15360 bits in size. .PP Some restrictions can be gracefully handled: for example cipher suites offering insufficient security are not sent by the client and will not be selected by the server. Other restrictions such as the peer certificate key size or the \s-1DH\s0 parameter size will abort the handshake with a fatal alert. .PP Attempts to set certificates or parameters with insufficient security are also blocked. For example trying to set a certificate using a 512 bit \s-1RSA\s0 key using \fBSSL_CTX_use_certificate()\fR at level 1. Applications which do not check the return values for errors will misbehave: for example it might appear that a certificate is not set at all because it had been rejected. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set_security_level()\fR and \fBSSL_set_security_level()\fR do not return values. .PP \&\fBSSL_CTX_get_security_level()\fR and \fBSSL_get_security_level()\fR return a integer that represents the security level with \fB\s-1SSL_CTX\s0\fR or \fB\s-1SSL\s0\fR, respectively. .PP \&\fBSSL_CTX_set_security_callback()\fR and \fBSSL_set_security_callback()\fR do not return values. .PP \&\fBSSL_CTX_get_security_callback()\fR and \fBSSL_get_security_callback()\fR return the pointer to the security callback or \s-1NULL\s0 if the callback is not set. .PP \&\fBSSL_CTX_get0_security_ex_data()\fR and \fBSSL_get0_security_ex_data()\fR return the extra data pointer or \s-1NULL\s0 if the ex data is not set. .SH "HISTORY" .IX Header "HISTORY" These functions were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2014\-2020 The OpenSSL Project Authors.

The certificates available via \fBCAfile\fR and \fBCApath\fR are trusted. .PP \&\fBSSL_CTX_set_default_verify_paths()\fR specifies that the default locations from which \s-1CA\s0 certificates are loaded should be used. There is one default directory and one default file. The default \s-1CA\s0 certificates directory is called \*(L"certs\*(R" in the default OpenSSL directory. Alternatively the \s-1SSL_CERT_DIR\s0 environment variable can be defined to override this location. The default \s-1CA\s0 certificates file is called \*(L"cert.pem\*(R" in the default OpenSSL directory. Alternatively the \&\s-1SSL_CERT_FILE\s0 environment variable can be defined to override this location. .PP \&\fBSSL_CTX_set_default_verify_dir()\fR is similar to \&\fBSSL_CTX_set_default_verify_paths()\fR except that just the default directory is used. .PP \&\fBSSL_CTX_set_default_verify_file()\fR is similar to \&\fBSSL_CTX_set_default_verify_paths()\fR except that just the default file is used. .SH "NOTES" .IX Header "NOTES" If \fBCAfile\fR is not \s-1NULL,\s0 it points to a file of \s-1CA\s0 certificates in \s-1PEM\s0 format. The file can contain several \s-1CA\s0 certificates identified by .PP .Vb 3 \& \-\-\-\-\-BEGIN CERTIFICATE\-\-\-\-\- \& ... (CA certificate in base64 encoding) ... \& \-\-\-\-\-END CERTIFICATE\-\-\-\-\- .Ve .PP sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. .PP The \fBCAfile\fR is processed on execution of the \fBSSL_CTX_load_verify_locations()\fR function. .PP If \fBCApath\fR is not \s-1NULL,\s0 it points to a directory containing \s-1CA\s0 certificates in \s-1PEM\s0 format. The files each contain one \s-1CA\s0 certificate. The files are looked up by the \s-1CA\s0 subject name hash value, which must hence be available. If more than one \s-1CA\s0 certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). The search is performed in the ordering of the extension number, regardless of other properties of the certificates. Use the \fBc_rehash\fR utility to create the necessary links. .PP The certificates in \fBCApath\fR are only looked up when required, e.g. when building the certificate chain or when actually performing the verification of a peer certificate. .PP When looking up \s-1CA\s0 certificates, the OpenSSL library will first search the certificates in \fBCAfile\fR, then those in \fBCApath\fR. Certificate matching is done based on the subject name, the key identifier (if present), and the serial number as taken from the certificate to be verified. If these data do not match, the next certificate will be tried. If a first certificate matching the parameters is found, the verification process will be performed; no other certificates for the same parameters will be searched in case of failure. .PP In server mode, when requesting a client certificate, the server must send the list of CAs of which it will accept client certificates. This list is not influenced by the contents of \fBCAfile\fR or \fBCApath\fR and must explicitly be set using the \&\fBSSL_CTX_set_client_CA_list\fR\|(3) family of functions. .PP When building its own certificate chain, an OpenSSL client/server will try to fill in missing certificates from \fBCAfile\fR/\fBCApath\fR, if the certificate chain was not explicitly specified (see \&\fBSSL_CTX_add_extra_chain_cert\fR\|(3), \&\fBSSL_CTX_use_certificate\fR\|(3). .SH "WARNINGS" .IX Header "WARNINGS" If several \s-1CA\s0 certificates matching the name, key identifier, and serial number condition are available, only the first one will be examined. This may lead to unexpected results if the same \s-1CA\s0 certificate is available with different expiration dates.

However, even where the ClientHello callback is used, the servername callback is still necessary in order to acknowledge the servername requested by the client. .PP \&\fBSSL_CTX_set_tlsext_servername_callback()\fR sets the application callback \fBcb\fR used by a server to perform any actions or configuration required based on the servername extension received in the incoming connection. When \fBcb\fR is \s-1NULL, SNI\s0 is not used. .PP The servername callback should return one of the following values: .IP "\s-1SSL_TLSEXT_ERR_OK\s0" 4 .IX Item "SSL_TLSEXT_ERR_OK" This is used to indicate that the servername requested by the client has been accepted. Typically a server will call \fBSSL_set_SSL_CTX()\fR in the callback to set up a different configuration for the selected servername in this case. .IP "\s-1SSL_TLSEXT_ERR_ALERT_FATAL\s0" 4 .IX Item "SSL_TLSEXT_ERR_ALERT_FATAL" In this case the servername requested by the client is not accepted and the handshake will be aborted. The value of the alert to be used should be stored in the location pointed to by the \fBal\fR parameter to the callback. By default this value is initialised to \s-1SSL_AD_UNRECOGNIZED_NAME.\s0 .IP "\s-1SSL_TLSEXT_ERR_ALERT_WARNING\s0" 4 .IX Item "SSL_TLSEXT_ERR_ALERT_WARNING" If this value is returned then the servername is not accepted by the server. However, the handshake will continue and send a warning alert instead. The value of the alert should be stored in the location pointed to by the \fBal\fR parameter as for \s-1SSL_TLSEXT_ERR_ALERT_FATAL\s0 above. Note that TLSv1.3 does not support warning alerts, so if TLSv1.3 has been negotiated then this return value is treated the same way as \s-1SSL_TLSEXT_ERR_NOACK.\s0 .IP "\s-1SSL_TLSEXT_ERR_NOACK\s0" 4 .IX Item "SSL_TLSEXT_ERR_NOACK" This return value indicates that the servername is not accepted by the server. No alerts are sent and the server will not acknowledge the requested servername. .PP \&\fBSSL_CTX_set_tlsext_servername_arg()\fR sets a context-specific argument to be passed into the callback (via the \fBarg\fR parameter) for this \fB\s-1SSL_CTX\s0\fR. .PP The behaviour of \fBSSL_get_servername()\fR depends on a number of different factors. In particular note that in TLSv1.3 the servername is negotiated in every handshake. In TLSv1.2 the servername is only negotiated on initial handshakes and not on resumption handshakes. .IP "On the client, before the handshake" 4 .IX Item "On the client, before the handshake" If a servername has been set via a call to \fBSSL_set_tlsext_host_name()\fR then it will return that servername. .Sp If one has not been set, but a TLSv1.2 resumption is being attempted and the session from the original handshake had a servername accepted by the server then it will return that servername. .Sp Otherwise it returns \s-1NULL.\s0 .IP "On the client, during or after the handshake and a TLSv1.2 (or below) resumption occurred" 4 .IX Item "On the client, during or after the handshake and a TLSv1.2 (or below) resumption occurred" If the session from the original handshake had a servername accepted by the server then it will return that servername. .Sp Otherwise it returns the servername set via \fBSSL_set_tlsext_host_name()\fR or \s-1NULL\s0 if it was not called. .IP "On the client, during or after the handshake and a TLSv1.2 (or below) resumption did not occur" 4 .IX Item "On the client, during or after the handshake and a TLSv1.2 (or below) resumption did not occur" It will return the servername set via \fBSSL_set_tlsext_host_name()\fR or \s-1NULL\s0 if it was not called. .IP "On the server, before the handshake" 4 .IX Item "On the server, before the handshake" The function will always return \s-1NULL\s0 before the handshake .IP "On the server, after the servername extension has been processed and a TLSv1.2 (or below) resumption occurred" 4 .IX Item "On the server, after the servername extension has been processed and a TLSv1.2 (or below) resumption occurred" If a servername was accepted by the server in the original handshake then it will return that servername, or \s-1NULL\s0 otherwise. .IP "On the server, after the servername extension has been processed and a TLSv1.2 (or below) resumption did not occur" 4 .IX Item "On the server, after the servername extension has been processed and a TLSv1.2 (or below) resumption did not occur" The function will return the servername requested by the client in this handshake or \s-1NULL\s0 if none was requested. .PP Note that the ClientHello callback occurs before a servername extension from the client is processed. The servername, certificate and \s-1ALPN\s0 callbacks occur after a servername extension from the client is processed. .PP \&\fBSSL_get_servername_type()\fR returns the servername type or \-1 if no servername is present. Currently the only supported type (defined in \s-1RFC3546\s0) is \&\fBTLSEXT_NAMETYPE_host_name\fR. .PP \&\fBSSL_set_tlsext_host_name()\fR sets the server name indication ClientHello extension to contain the value \fBname\fR. The type of server name indication extension is set to \fBTLSEXT_NAMETYPE_host_name\fR (defined in \s-1RFC3546\s0). .SH "NOTES" .IX Header "NOTES" Several callbacks are executed during ClientHello processing, including the ClientHello, \s-1ALPN,\s0 and servername callbacks. The ClientHello callback is executed first, then the servername callback, followed by the \s-1ALPN\s0 callback. .PP The \fBSSL_set_tlsext_host_name()\fR function should only be called on \s-1SSL\s0 objects that will act as clients; otherwise the configured \fBname\fR will be ignored. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_CTX_set_tlsext_servername_callback()\fR and \&\fBSSL_CTX_set_tlsext_servername_arg()\fR both always return 1 indicating success. \&\fBSSL_set_tlsext_host_name()\fR returns 1 on success, 0 in case of error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_CTX_set_alpn_select_cb\fR\|(3), \&\fBSSL_get0_alpn_selected\fR\|(3), \fBSSL_CTX_set_client_hello_cb\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\fBSSL_get_servername()\fR historically provided some unexpected results in certain corner cases. This has been fixed from OpenSSL 1.1.1e. .PP Prior to 1.1.1e, when the client requested a servername in an initial TLSv1.2 handshake, the server accepted it, and then the client successfully resumed but set a different explicit servername in the second handshake then when called by the client it returned the servername from the second handshake. This has now been changed to return the servername requested in the original handshake. .PP Also prior to 1.1.1e, if the client sent a servername in the first handshake but the server did not accept it, and then a second handshake occurred where TLSv1.2 resumption was successful then when called by the server it returned the servername requested in the original handshake.

If the nonce is present in the request only then \-1 is returned. .SH "NOTES" .IX Header "NOTES" For most purposes the nonce value in a request is set to a random value so the \fBval\fR parameter in \fBOCSP_request_add1_nonce()\fR is usually \s-1NULL.\s0 .PP An \s-1OCSP\s0 nonce is typically added to an \s-1OCSP\s0 request to thwart replay attacks by checking the same nonce value appears in the response. .PP Some responders may include a nonce in all responses even if one is not supplied. .PP Some responders cache \s-1OCSP\s0 responses and do not sign each response for performance reasons. As a result they do not support nonces. .PP The return values of \fBOCSP_check_nonce()\fR can be checked to cover each case. A positive return value effectively indicates success: nonces are both present and match, both absent or present in the response only. A nonzero return additionally covers the case where the nonce is present in the request only: this will happen if the responder doesn't support nonces.

A completed operation will result in data appearing as \*(L"read ready\*(R" on the file descriptor (no actual data should be read from the file descriptor). This function should only be called if the \s-1SSL\s0 object is currently waiting for asynchronous work to complete (i.e. \&\s-1SSL_ERROR_WANT_ASYNC\s0 has been received \- see \fBSSL_get_error\fR\|(3)). Typically the list will only contain one file descriptor. However, if multiple asynchronous capable engines are in use then more than one is possible. The number of file descriptors returned is stored in \fB*numfds\fR and the file descriptors themselves are in \fB*fds\fR. The \fBfds\fR parameter may be \s-1NULL\s0 in which case no file descriptors are returned but \fB*numfds\fR is still populated. It is the callers responsibility to ensure sufficient memory is allocated at \fB*fds\fR so typically this function is called twice (once with a \s-1NULL\s0 \fBfds\fR parameter and once without). .PP \&\fBSSL_get_changed_async_fds()\fR returns a list of the asynchronous file descriptors that have been added and a list that have been deleted since the last \&\s-1SSL_ERROR_WANT_ASYNC\s0 was received (or since the \s-1SSL\s0 object was created if no \&\s-1SSL_ERROR_WANT_ASYNC\s0 has been received). Similar to \fBSSL_get_all_async_fds()\fR it is the callers responsibility to ensure that \fB*addfd\fR and \fB*delfd\fR have sufficient memory allocated, although they may be \s-1NULL.\s0 The number of added fds and the number of deleted fds are stored in \fB*numaddfds\fR and \fB*numdelfds\fR respectively. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_waiting_for_async()\fR will return 1 if the current \s-1SSL\s0 operation is waiting for an async operation to complete and 0 otherwise. .PP \&\fBSSL_get_all_async_fds()\fR and \fBSSL_get_changed_async_fds()\fR return 1 on success or 0 on error. .SH "NOTES" .IX Header "NOTES" On Windows platforms the openssl/async.h header is dependent on some of the types customarily made available by including windows.h.

It verifies a \&\fB\s-1CMS\s0 SignedData\fR structure contained in a structure of type \fBCMS_ContentInfo\fR. \&\fIcms\fR points to the \fBCMS_ContentInfo\fR structure to verify. The optional \fIcerts\fR parameter refers to a set of certificates in which to search for signing certificates. \&\fIcms\fR may contain extra untrusted \s-1CA\s0 certificates that may be used for chain building as well as CRLs that may be used for certificate validation. \&\fIstore\fR may be \s-1NULL\s0 or point to the trusted certificate store to use for chain verification. \&\fIindata\fR refers to the signed data if the content is detached from \fIcms\fR. Otherwise \fIindata\fR should be \s-1NULL\s0 and the signed data must be in \fIcms\fR. The content is written to the \s-1BIO\s0 \fIout\fR unless it is \s-1NULL.\s0 \&\fIflags\fR is an optional set of flags, which can be used to modify the operation. .PP \&\fBCMS_get0_signers()\fR retrieves the signing certificate(s) from \fIcms\fR, it may only be called after a successful \fBCMS_verify()\fR operation. .SH "VERIFY PROCESS" .IX Header "VERIFY PROCESS" Normally the verify process proceeds as follows. .PP Initially some sanity checks are performed on \fIcms\fR. The type of \fIcms\fR must be SignedData. There must be at least one signature on the data and if the content is detached \fIindata\fR cannot be \s-1NULL.\s0 .PP An attempt is made to locate all the signing certificate(s), first looking in the \fIcerts\fR parameter (if it is not \s-1NULL\s0) and then looking in any certificates contained in the \fIcms\fR structure unless \fB\s-1CMS_NOINTERN\s0\fR is set. If any signing certificate cannot be located the operation fails. .PP Each signing certificate is chain verified using the \fIsmimesign\fR purpose and using the trusted certificate store \fIstore\fR if supplied. Any internal certificates in the message, which may have been added using \&\fBCMS_add1_cert\fR\|(3), are used as untrusted CAs. If \s-1CRL\s0 checking is enabled in \fIstore\fR and \fB\s-1CMS_NOCRL\s0\fR is not set, any internal CRLs, which may have been added using \fBCMS_add1_crl\fR\|(3), are used in addition to attempting to look them up in \fIstore\fR. If \fIstore\fR is not \s-1NULL\s0 and any chain verify fails an error code is returned. .PP Finally the signed content is read (and written to \fIout\fR unless it is \s-1NULL\s0) and the signature is checked. .PP If all signatures verify correctly then the function is successful. .PP Any of the following flags (ored together) can be passed in the \fIflags\fR parameter to change the default verify behaviour. .PP If \fB\s-1CMS_NOINTERN\s0\fR is set the certificates in the message itself are not searched when locating the signing certificate(s). This means that all the signing certificates must be in the \fIcerts\fR parameter. .PP If \fB\s-1CMS_NOCRL\s0\fR is set and \s-1CRL\s0 checking is enabled in \fIstore\fR then any CRLs in the message itself are ignored. .PP If the \fB\s-1CMS_TEXT\s0\fR flag is set \s-1MIME\s0 headers for type \fBtext/plain\fR are deleted from the content. If the content is not of type \fBtext/plain\fR then an error is returned. .PP If \fB\s-1CMS_NO_SIGNER_CERT_VERIFY\s0\fR is set the signing certificates are not chain verified. .PP If \fB\s-1CMS_NO_ATTR_VERIFY\s0\fR is set the signed attributes signature is not verified. .PP If \fB\s-1CMS_NO_CONTENT_VERIFY\s0\fR is set then the content digest is not checked. .SH "NOTES" .IX Header "NOTES" One application of \fB\s-1CMS_NOINTERN\s0\fR is to only accept messages signed by a small number of certificates. The acceptable certificates would be passed in the \fIcerts\fR parameter. In this case if the signer certificate is not one of the certificates supplied in \fIcerts\fR then the verify will fail because the signer cannot be found. .PP In some cases the standard techniques for looking up and validating certificates are not appropriate: for example an application may wish to lookup certificates in a database or perform customised verification. This can be achieved by setting and verifying the signer certificates manually using the signed data utility functions. .PP Care should be taken when modifying the default verify behaviour, for example setting \fB\s-1CMS_NO_CONTENT_VERIFY\s0\fR will totally disable all content verification and any modified content will be considered valid. This combination is however useful if one merely wishes to write the content to \fIout\fR and its validity is not considered important. .PP Chain verification should arguably be performed using the signing time rather than the current time. However, since the signing time is supplied by the signer it cannot be trusted without additional evidence (such as a trusted timestamp). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBCMS_verify()\fR returns 1 for a successful verification and 0 if an error occurred. .PP \&\fBCMS_get0_signers()\fR returns all signers or \s-1NULL\s0 if an error occurred. .PP The error can be obtained from \fBERR_get_error\fR\|(3) .SH "BUGS" .IX Header "BUGS" The trusted certificate store is not searched for the signing certificate. This is primarily due to the inadequacies of the current \fBX509_STORE\fR functionality. .PP The lack of single pass processing means that the signed content must all be held in memory if it is not detached. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBPKCS7_verify\fR\|(3), \fBCMS_add1_cert\fR\|(3), \fBCMS_add1_crl\fR\|(3), \&\fBOSSL_ESS_check_signing_certs\fR\|(3), \&\fBERR_get_error\fR\|(3), \fBCMS_sign\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2008\-2022 The OpenSSL Project Authors.

The parameter \fBidx\fR indicates the index of the shared signature algorithm to return starting from zero. The signature algorithm \s-1NID\s0 is written to \fB*psign\fR, the hash \s-1NID\s0 to \fB*phash\fR and the sign and hash \s-1NID\s0 to \fB*psignhash\fR. The raw signature and hash values are written to \fB*rsig\fR and \fB*rhash\fR. .PP \&\fBSSL_get_sigalgs()\fR is similar to \fBSSL_get_shared_sigalgs()\fR except it returns information about all signature algorithms supported by \fBs\fR in the order they were sent by the peer. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_get_shared_sigalgs()\fR and \fBSSL_get_sigalgs()\fR return the number of signature algorithms or \fB0\fR if the \fBidx\fR parameter is out of range. .SH "NOTES" .IX Header "NOTES" These functions are typically called for debugging purposes (to report the peer's preferences) or where an application wants finer control over certificate selection. Most applications will rely on internal handling and will not need to call them. .PP If an application is only interested in the highest preference shared signature algorithm it can just set \fBidx\fR to zero. .PP Any or all of the parameters \fBpsign\fR, \fBphash\fR, \fBpsignhash\fR, \fBrsig\fR or \&\fBrhash\fR can be set to \fB\s-1NULL\s0\fR if the value is not required. By setting them all to \fB\s-1NULL\s0\fR and setting \fBidx\fR to zero the total number of signature algorithms can be determined: which can be zero. .PP These functions must be called after the peer has sent a list of supported signature algorithms: after a client hello (for servers) or a certificate request (for clients). They can (for example) be called in the certificate callback. .PP Only \s-1TLS 1.2, TLS 1.3\s0 and \s-1DTLS 1.2\s0 currently support signature algorithms. If these functions are called on an earlier version of \s-1TLS\s0 or \s-1DTLS\s0 zero is returned. .PP The shared signature algorithms returned by \fBSSL_get_shared_sigalgs()\fR are ordered according to configuration and peer preferences. .PP The raw values correspond to the on the wire form as defined by \s-1RFC5246\s0 et al. The NIDs are OpenSSL equivalents. For example if the peer sent \fBsha256\fR\|(4) and \&\fBrsa\fR\|(1) then \fB*rhash\fR would be 4, \fB*rsign\fR 1, \fB*phash\fR NID_sha256, \fB*psig\fR NID_rsaEncryption and \fB*psighash\fR NID_sha256WithRSAEncryption. .PP If a signature algorithm is not recognised the corresponding NIDs will be set to \fBNID_undef\fR. This may be because the value is not supported, is not an appropriate combination (for example \s-1MD5\s0 and \s-1DSA\s0) or the signature algorithm does not use a hash (for example Ed25519). .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CTX_set_cert_cb\fR\|(3), \&\fBssl\fR\|(7) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2015\-2018 The OpenSSL Project Authors.

These extensions are denoted by individual bits in capability vector returned by processor in \s-1EDX:ECX\s0 register pair after executing \s-1CPUID\s0 instruction with EAX=1 input value (see Intel Application Note #241618). This vector is copied to memory upon toolkit initialization and used to choose between different code paths to provide optimal performance across wide range of processors. For the moment of this writing following bits are significant: .IP "bit #4 denoting presence of Time-Stamp Counter." 4 .IX Item "bit #4 denoting presence of Time-Stamp Counter." .PD 0 .IP "bit #19 denoting availability of \s-1CLFLUSH\s0 instruction;" 4 .IX Item "bit #19 denoting availability of CLFLUSH instruction;" .IP "bit #20, reserved by Intel, is used to choose among \s-1RC4\s0 code paths;" 4 .IX Item "bit #20, reserved by Intel, is used to choose among RC4 code paths;" .IP "bit #23 denoting \s-1MMX\s0 support;" 4 .IX Item "bit #23 denoting MMX support;" .IP "bit #24, \s-1FXSR\s0 bit, denoting availability of \s-1XMM\s0 registers;" 4 .IX Item "bit #24, FXSR bit, denoting availability of XMM registers;" .IP "bit #25 denoting \s-1SSE\s0 support;" 4 .IX Item "bit #25 denoting SSE support;" .IP "bit #26 denoting \s-1SSE2\s0 support;" 4 .IX Item "bit #26 denoting SSE2 support;" .IP "bit #28 denoting Hyperthreading, which is used to distinguish cores with shared cache;" 4 .IX Item "bit #28 denoting Hyperthreading, which is used to distinguish cores with shared cache;" .IP "bit #30, reserved by Intel, denotes specifically Intel CPUs;" 4 .IX Item "bit #30, reserved by Intel, denotes specifically Intel CPUs;" .IP "bit #33 denoting availability of \s-1PCLMULQDQ\s0 instruction;" 4 .IX Item "bit #33 denoting availability of PCLMULQDQ instruction;" .IP "bit #41 denoting \s-1SSSE3,\s0 Supplemental \s-1SSE3,\s0 support;" 4 .IX Item "bit #41 denoting SSSE3, Supplemental SSE3, support;" .IP "bit #43 denoting \s-1AMD XOP\s0 support (forced to zero on non-AMD CPUs);" 4 .IX Item "bit #43 denoting AMD XOP support (forced to zero on non-AMD CPUs);" .IP "bit #54 denoting availability of \s-1MOVBE\s0 instruction;" 4 .IX Item "bit #54 denoting availability of MOVBE instruction;" .IP "bit #57 denoting AES-NI instruction set extension;" 4 .IX Item "bit #57 denoting AES-NI instruction set extension;" .IP "bit #58, \s-1XSAVE\s0 bit, lack of which in combination with \s-1MOVBE\s0 is used to identify Atom Silvermont core;" 4 .IX Item "bit #58, XSAVE bit, lack of which in combination with MOVBE is used to identify Atom Silvermont core;" .IP "bit #59, \s-1OSXSAVE\s0 bit, denoting availability of \s-1YMM\s0 registers;" 4 .IX Item "bit #59, OSXSAVE bit, denoting availability of YMM registers;" .IP "bit #60 denoting \s-1AVX\s0 extension;" 4 .IX Item "bit #60 denoting AVX extension;" .IP "bit #62 denoting availability of \s-1RDRAND\s0 instruction;" 4 .IX Item "bit #62 denoting availability of RDRAND instruction;" .PD .PP For example, in 32\-bit application context clearing bit #26 at run-time disables high-performance \s-1SSE2\s0 code present in the crypto library, while clearing bit #24 disables \s-1SSE2\s0 code operating on 128\-bit \s-1XMM\s0 register bank. You might have to do the latter if target OpenSSL application is executed on \s-1SSE2\s0 capable \s-1CPU,\s0 but under control of \s-1OS\s0 that does not enable \s-1XMM\s0 registers. Historically address of the capability vector copy was exposed to application through \fBOPENSSL_ia32cap_loc()\fR, but not anymore. Now the only way to affect the capability detection is to set OPENSSL_ia32cap environment variable prior target application start. To give a specific example, on Intel P4 processor 'env OPENSSL_ia32cap=0x16980010 apps/openssl', or better yet 'env OPENSSL_ia32cap=~0x1000000 apps/openssl' would achieve the desired effect. Alternatively you can reconfigure the toolkit with no\-sse2 option and recompile. .PP Less intuitive is clearing bit #28, or ~0x10000000 in the \*(L"environment variable\*(R" terms. The truth is that it's not copied from \s-1CPUID\s0 output verbatim, but is adjusted to reflect whether or not the data cache is actually shared between logical cores. This in turn affects the decision on whether or not expensive countermeasures against cache-timing attacks are applied, most notably in \s-1AES\s0 assembler module. .PP The capability vector is further extended with \s-1EBX\s0 value returned by \&\s-1CPUID\s0 with EAX=7 and ECX=0 as input. Following bits are significant: .IP "bit #64+3 denoting availability of \s-1BMI1\s0 instructions, e.g. \s-1ANDN\s0;" 4 .IX Item "bit #64+3 denoting availability of BMI1 instructions, e.g. ANDN;" .PD 0 .IP "bit #64+5 denoting availability of \s-1AVX2\s0 instructions;" 4 .IX Item "bit #64+5 denoting availability of AVX2 instructions;" .IP "bit #64+8 denoting availability of \s-1BMI2\s0 instructions, e.g. \s-1MULX\s0 and \s-1RORX\s0;" 4 .IX Item "bit #64+8 denoting availability of BMI2 instructions, e.g. MULX and RORX;" .IP "bit #64+16 denoting availability of \s-1AVX512F\s0 extension;" 4 .IX Item "bit #64+16 denoting availability of AVX512F extension;" .IP "bit #64+18 denoting availability of \s-1RDSEED\s0 instruction;" 4 .IX Item "bit #64+18 denoting availability of RDSEED instruction;" .IP "bit #64+19 denoting availability of \s-1ADCX\s0 and \s-1ADOX\s0 instructions;" 4 .IX Item "bit #64+19 denoting availability of ADCX and ADOX instructions;" .IP "bit #64+21 denoting availability of VPMADD52[\s-1LH\s0]UQ instructions, aka \s-1AVX512IFMA\s0 extension;" 4 .IX Item "bit #64+21 denoting availability of VPMADD52[LH]UQ instructions, aka AVX512IFMA extension;" .IP "bit #64+29 denoting availability of \s-1SHA\s0 extension;" 4 .IX Item "bit #64+29 denoting availability of SHA extension;" .IP "bit #64+30 denoting availability of \s-1AVX512BW\s0 extension;" 4 .IX Item "bit #64+30 denoting availability of AVX512BW extension;" .IP "bit #64+31 denoting availability of \s-1AVX512VL\s0 extension;" 4 .IX Item "bit #64+31 denoting availability of AVX512VL extension;" .IP "bit #64+41 denoting availability of \s-1VAES\s0 extension;" 4 .IX Item "bit #64+41 denoting availability of VAES extension;" .IP "bit #64+42 denoting availability of \s-1VPCLMULQDQ\s0 extension;" 4 .IX Item "bit #64+42 denoting availability of VPCLMULQDQ extension;" .PD .PP To control this extended capability word use ':' as delimiter when setting up OPENSSL_ia32cap environment variable. For example assigning \&':~0x20' would disable \s-1AVX2\s0 code paths, and ':0' \- all post-AVX extensions. .PP It should be noted that whether or not some of the most \*(L"fancy\*(R" extension code paths are actually assembled depends on current assembler version. Base minimum of \s-1AES\-NI/PCLMULQDQ, SSSE3\s0 and \s-1SHA\s0 extension code paths are always assembled. Apart from that, minimum assembler version requirements are summarized in below table: .PP .Vb 8 \& Extension | GNU as | nasm | llvm \& \-\-\-\-\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\-+\-\-\-\-\-\-\-\- \& AVX | 2.19 | 2.09 | 3.0 \& AVX2 | 2.22 | 2.10 | 3.1 \& ADCX/ADOX | 2.23 | 2.10 | 3.3 \& AVX512 | 2.25 | 2.11.8 | see NOTES \& AVX512IFMA | 2.26 | 2.11.8 | see NOTES \& VAES | 2.30 | 2.13.3 | .Ve .SH "NOTES" .IX Header "NOTES" Even though \s-1AVX512\s0 support was implemented in llvm 3.6, compilation of assembly modules apparently requires explicit \-march flag. But then compiler generates processor-specific code, which in turn contradicts the mere idea of run-time switch execution facilitated by the variable in question. Till the limitation is lifted, it's possible to work around the problem by making build procedure use following script: .PP .Vb 2 \& #!/bin/sh \& exec clang \-no\-integrated\-as "$@" .Ve .PP instead of real clang. In which case it doesn't matter which clang version is used, as it is \s-1GNU\s0 assembler version that will be checked. .SH "RETURN VALUES" .IX Header "RETURN VALUES" Not available. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2004\-2020 The OpenSSL Project Authors.

On success \fBSSL_write_ex()\fR will store the number of bytes written in \fB*written\fR. .SH "NOTES" .IX Header "NOTES" In the paragraphs below a \*(L"write function\*(R" is defined as one of either \&\fBSSL_write_ex()\fR, or \fBSSL_write()\fR. .PP If necessary, a write function will negotiate a \s-1TLS/SSL\s0 session, if not already explicitly performed by \fBSSL_connect\fR\|(3) or \fBSSL_accept\fR\|(3). If the peer requests a re-negotiation, it will be performed transparently during the write function operation. The behaviour of the write functions depends on the underlying \s-1BIO.\s0 .PP For the transparent negotiation to succeed, the \fBssl\fR must have been initialized to client or server mode. This is being done by calling \&\fBSSL_set_connect_state\fR\|(3) or \fBSSL_set_accept_state()\fR before the first call to a write function. .PP If the underlying \s-1BIO\s0 is \fBblocking\fR, the write functions will only return, once the write operation has been finished or an error occurred. .PP If the underlying \s-1BIO\s0 is \fBnonblocking\fR the write functions will also return when the underlying \s-1BIO\s0 could not satisfy the needs of the function to continue the operation. In this case a call to \fBSSL_get_error\fR\|(3) with the return value of the write function will yield \fB\s-1SSL_ERROR_WANT_READ\s0\fR or \fB\s-1SSL_ERROR_WANT_WRITE\s0\fR. As at any time a re-negotiation is possible, a call to a write function can also cause read operations! The calling process then must repeat the call after taking appropriate action to satisfy the needs of the write function. The action depends on the underlying \s-1BIO.\s0 When using a nonblocking socket, nothing is to be done, but \fBselect()\fR can be used to check for the required condition. When using a buffering \s-1BIO,\s0 like a \s-1BIO\s0 pair, data must be written into or retrieved out of the \s-1BIO\s0 before being able to continue. .PP The write functions will only return with success when the complete contents of \&\fBbuf\fR of length \fBnum\fR has been written. This default behaviour can be changed with the \s-1SSL_MODE_ENABLE_PARTIAL_WRITE\s0 option of \fBSSL_CTX_set_mode\fR\|(3). When this flag is set the write functions will also return with success when a partial write has been successfully completed. In this case the write function operation is considered completed. The bytes are sent and a new write call with a new buffer (with the already sent bytes removed) must be started. A partial write is performed with the size of a message block, which is 16kB. .SH "WARNINGS" .IX Header "WARNINGS" When a write function call has to be repeated because \fBSSL_get_error\fR\|(3) returned \fB\s-1SSL_ERROR_WANT_READ\s0\fR or \fB\s-1SSL_ERROR_WANT_WRITE\s0\fR, it must be repeated with the same arguments. The data that was passed might have been partially processed. When \fB\s-1SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER\s0\fR was set using \fBSSL_CTX_set_mode\fR\|(3) the pointer can be different, but the data and length should still be the same. .PP You should not call \fBSSL_write()\fR with num=0, it will return an error. \&\fBSSL_write_ex()\fR can be called with num=0, but will not send application data to the peer. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_write_ex()\fR will return 1 for success or 0 for failure. Success means that all requested application data bytes have been written to the \s-1SSL\s0 connection or, if \s-1SSL_MODE_ENABLE_PARTIAL_WRITE\s0 is in use, at least 1 application data byte has been written to the \s-1SSL\s0 connection. Failure means that not all the requested bytes have been written yet (if \s-1SSL_MODE_ENABLE_PARTIAL_WRITE\s0 is not in use) or no bytes could be written to the \s-1SSL\s0 connection (if \&\s-1SSL_MODE_ENABLE_PARTIAL_WRITE\s0 is in use). Failures can be retryable (e.g. the network write buffer has temporarily filled up) or non-retryable (e.g. a fatal network error). In the event of a failure call \fBSSL_get_error\fR\|(3) to find out the reason which indicates whether the call is retryable or not. .PP For \fBSSL_write()\fR the following return values can occur: .IP "> 0" 4 .IX Item "> 0" The write operation was successful, the return value is the number of bytes actually written to the \s-1TLS/SSL\s0 connection. .IP "<= 0" 4 .IX Item "<= 0" The write operation was not successful, because either the connection was closed, an error occurred or action must be taken by the calling process. Call \fBSSL_get_error()\fR with the return value \fBret\fR to find out the reason. .Sp Old documentation indicated a difference between 0 and \-1, and that \-1 was retryable.

This can be readily produced by storing the S/MIME signed message in a memory \s-1BIO\s0 and passing it to \&\fBPKCS7_encrypt()\fR. .PP The following flags can be passed in the \fBflags\fR parameter. .PP If the \fB\s-1PKCS7_TEXT\s0\fR flag is set \s-1MIME\s0 headers for type \fBtext/plain\fR are prepended to the data. .PP Normally the supplied content is translated into \s-1MIME\s0 canonical format (as required by the S/MIME specifications) if \fB\s-1PKCS7_BINARY\s0\fR is set no translation occurs. This option should be used if the supplied data is in binary format otherwise the translation will corrupt it. If \fB\s-1PKCS7_BINARY\s0\fR is set then \&\fB\s-1PKCS7_TEXT\s0\fR is ignored. .PP If the \fB\s-1PKCS7_STREAM\s0\fR flag is set a partial \fB\s-1PKCS7\s0\fR structure is output suitable for streaming I/O: no data is read from the \s-1BIO\s0 \fBin\fR. .SH "NOTES" .IX Header "NOTES" If the flag \fB\s-1PKCS7_STREAM\s0\fR is set the returned \fB\s-1PKCS7\s0\fR structure is \fBnot\fR complete and outputting its contents via a function that does not properly finalize the \fB\s-1PKCS7\s0\fR structure will give unpredictable results. .PP Several functions including \fBSMIME_write_PKCS7()\fR, \fBi2d_PKCS7_bio_stream()\fR, \&\fBPEM_write_bio_PKCS7_stream()\fR finalize the structure.

On all major platforms supported by OpenSSL (including the Unix-like platforms and Windows), OpenSSL is configured to automatically seed the \s-1CSPRNG\s0 on first use using the operating systems's random generator. .PP If the entropy source fails or is not available, the \s-1CSPRNG\s0 will enter an error state and refuse to generate random bytes. For that reason, it is important to always check the error return value of \fBRAND_bytes()\fR and \fBRAND_priv_bytes()\fR and not take randomness for granted. .PP On other platforms, there might not be a trusted entropy source available or OpenSSL might have been explicitly configured to use different entropy sources. If you are in doubt about the quality of the entropy source, don't hesitate to ask your operating system vendor or post a question on GitHub or the openssl-users mailing list. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBRAND_bytes()\fR and \fBRAND_priv_bytes()\fR return 1 on success, \-1 if not supported by the current \&\s-1RAND\s0 method, or 0 on other failure.

The \fBsalt\fR parameter is used as a salt in the derivation: it should point to an 8 byte buffer or \s-1NULL\s0 if no salt is used. \fBdata\fR is a buffer containing \&\fBdatal\fR bytes which is used to derive the keying data. \fBcount\fR is the iteration count to use. The derived key and \s-1IV\s0 will be written to \fBkey\fR and \fBiv\fR respectively. .SH "NOTES" .IX Header "NOTES" A typical application of this function is to derive keying material for an encryption algorithm from a password in the \fBdata\fR parameter. .PP Increasing the \fBcount\fR parameter slows down the algorithm which makes it harder for an attacker to perform a brute force attack using a large number of candidate passwords. .PP If the total key and \s-1IV\s0 length is less than the digest length and \&\fB\s-1MD5\s0\fR is used then the derivation algorithm is compatible with PKCS#5 v1.5 otherwise a non standard extension is used to derive the extra data. .PP Newer applications should use a more modern algorithm such as \s-1PBKDF2\s0 as defined in PKCS#5v2.1 and provided by \s-1PKCS5_PBKDF2_HMAC.\s0 .SH "KEY DERIVATION ALGORITHM" .IX Header "KEY DERIVATION ALGORITHM" The key and \s-1IV\s0 is derived by concatenating D_1, D_2, etc until enough data is available for the key and \s-1IV.\s0 D_i is defined as: .PP .Vb 1 \& D_i = HASH^count(D_(i\-1) || data || salt) .Ve .PP where || denotes concatenation, D_0 is empty, \s-1HASH\s0 is the digest algorithm in use, HASH^1(data) is simply \s-1HASH\s0(data), HASH^2(data) is \s-1HASH\s0(\s-1HASH\s0(data)) and so on. .PP The initial bytes are used for the key and the subsequent bytes for the \s-1IV.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" If \fBdata\fR is \s-1NULL,\s0 then \fBEVP_BytesToKey()\fR returns the number of bytes needed to store the derived key.

If multiple PEM-encoded data structures are present in the same stream, \fBPEM_bytes_read_bio()\fR will skip non-matching data types and continue reading. Non-PEM data present in the stream may cause an error. .PP The \s-1PEM\s0 header may indicate that the following data is encrypted; if so, the data will be decrypted, waiting on user input to supply a passphrase if needed. The password callback \fIcb\fR and rock \fIu\fR are used to obtain the decryption passphrase, if applicable. .PP Some data types have compatibility aliases, such as a file containing X509 \s-1CERTIFICATE\s0 matching a request for the deprecated type \s-1CERTIFICATE.\s0 The actual type indicated by the file is returned in \fI*pnm\fR if \fIpnm\fR is non-NULL.

The \s-1BIO\s0 stack from which input is read may also use temporary buffers, which are not necessarily allocated from the secure heap. In cases where it is desirable to ensure that the contents of the \s-1PEM\s0 file only appears in memory from the secure heap, care is needed in generating the \s-1BIO\s0 passed as \fIbp\fR.

Session tickets, defined in \&\s-1RFC5077\s0 provide an enhanced session resumption capability where the server implementation is not required to maintain per session state. It only applies to \s-1TLS\s0 and there is no SSLv3 implementation. .PP The callback function \fIcb\fR will be called for every client instigated \s-1TLS\s0 session when session ticket extension is presented in the \s-1TLS\s0 hello message. It is the responsibility of this function to create or retrieve the cryptographic parameters and to maintain their state. .PP The OpenSSL library uses your callback function to help implement a common \s-1TLS\s0 ticket construction state according to \s-1RFC5077\s0 Section 4 such that per session state is unnecessary and a small set of cryptographic variables needs to be maintained by the callback function implementation. .PP In order to reuse a session, a \s-1TLS\s0 client must send the a session ticket extension to the server. The client can only send exactly one session ticket. The server, through the callback function, either agrees to reuse the session ticket information or it starts a full \s-1TLS\s0 handshake to create a new session ticket. .PP Before the callback function is started \fIctx\fR and \fIhctx\fR have been initialised with \fBEVP_CIPHER_CTX_reset\fR\|(3) and \fBHMAC_CTX_reset\fR\|(3) respectively. .PP For new sessions tickets, when the client doesn't present a session ticket, or an attempted retrieval of the ticket failed, or a renew option was indicated, the callback function will be called with \fIenc\fR equal to 1. The OpenSSL library expects that the function will set an arbitrary \fIname\fR, initialize \&\fIiv\fR, and set the cipher context \fIctx\fR and the hash context \fIhctx\fR. .PP The \fIname\fR is 16 characters long and is used as a key identifier. .PP The \fIiv\fR length is the length of the \s-1IV\s0 of the corresponding cipher. The maximum \s-1IV\s0 length is \fB\s-1EVP_MAX_IV_LENGTH\s0\fR bytes defined in \fBevp.h\fR. .PP The initialization vector \fIiv\fR should be a random value. The cipher context \&\fIctx\fR should use the initialisation vector \fIiv\fR. The cipher context can be set using \fBEVP_EncryptInit_ex\fR\|(3). The hmac context can be set using \&\fBHMAC_Init_ex\fR\|(3). .PP When the client presents a session ticket, the callback function with be called with \fIenc\fR set to 0 indicating that the \fIcb\fR function should retrieve a set of parameters. In this case \fIname\fR and \fIiv\fR have already been parsed out of the session ticket. The OpenSSL library expects that the \fIname\fR will be used to retrieve a cryptographic parameters and that the cryptographic context \&\fIctx\fR will be set with the retrieved parameters and the initialization vector \&\fIiv\fR. using a function like \fBEVP_DecryptInit_ex\fR\|(3). The \fIhctx\fR needs to be set using \fBHMAC_Init_ex\fR\|(3). .PP If the \fIname\fR is still valid but a renewal of the ticket is required the callback function should return 2. The library will call the callback again with an argument of enc equal to 1 to set the new ticket. .PP The return value of the \fIcb\fR function is used by OpenSSL to determine what further processing will occur. The following return values have meaning: .IP "2" 4 .IX Item "2" This indicates that the \fIctx\fR and \fIhctx\fR have been set and the session can continue on those parameters. Additionally it indicates that the session ticket is in a renewal period and should be replaced. The OpenSSL library will call \fIcb\fR again with an enc argument of 1 to set the new ticket (see \s-1RFC5077 3.3\s0 paragraph 2). .IP "1" 4 .IX Item "1" This indicates that the \fIctx\fR and \fIhctx\fR have been set and the session can continue on those parameters. .IP "0" 4 This indicates that it was not possible to set/retrieve a session ticket and the \s-1SSL/TLS\s0 session will continue by negotiating a set of cryptographic parameters or using the alternate \s-1SSL/TLS\s0 resumption mechanism, session ids. .Sp If called with enc equal to 0 the library will call the \fIcb\fR again to get a new set of parameters. .IP "less than 0" 4 .IX Item "less than 0" This indicates an error. .SH "NOTES" .IX Header "NOTES" Session resumption shortcuts the \s-1TLS\s0 so that the client certificate negotiation don't occur. It makes up for this by storing client certificate an all other negotiated state information encrypted within the ticket. In a resumed session the applications will have all this state information available exactly as if a full negotiation had occurred. .PP If an attacker can obtain the key used to encrypt a session ticket, they can obtain the master secret for any ticket using that key and decrypt any traffic using that session: even if the cipher suite supports forward secrecy. As a result applications may wish to use multiple keys and avoid using long term keys stored in files. .PP Applications can use longer keys to maintain a consistent level of security. For example if a cipher suite uses 256 bit ciphers but only a 128 bit ticket key the overall security is only 128 bits because breaking the ticket key will enable an attacker to obtain the session keys. .SH "RETURN VALUES" .IX Header "RETURN VALUES" Returns 1 to indicate the callback function was set and 0 otherwise. .SH "EXAMPLES" .IX Header "EXAMPLES" Reference Implementation: .PP .Vb 2 \& SSL_CTX_set_tlsext_ticket_key_cb(SSL, ssl_tlsext_ticket_key_cb); \& ... \& \& static int ssl_tlsext_ticket_key_cb(SSL *s, unsigned char key_name[16], \& unsigned char *iv, EVP_CIPHER_CTX *ctx, \& HMAC_CTX *hctx, int enc) \& { \& your_type_t *key; /* something that you need to implement */ \& \& if (enc) { /* create new session */ \& if (RAND_bytes(iv, EVP_MAX_IV_LENGTH) <= 0) \& return \-1; /* insufficient random */ \& \& key = currentkey(); /* something that you need to implement */ \& if (key == NULL) { \& /* current key doesn\*(Aqt exist or isn\*(Aqt valid */ \& key = createkey(); /* \& * Something that you need to implement. \& * createkey needs to initialise a name, \& * an aes_key, a hmac_key and optionally \& * an expire time. \& */ \& if (key == NULL) /* key couldn\*(Aqt be created */ \& return 0; \& } \& memcpy(key_name, key\->name, 16); \& \& EVP_EncryptInit_ex(&ctx, EVP_aes_256_cbc(), NULL, key\->aes_key, iv); \& HMAC_Init_ex(&hctx, key\->hmac_key, 32, EVP_sha256(), NULL); \& \& return 1; \& \& } else { /* retrieve session */ \& time_t t = time(NULL); \& key = findkey(key_name); /* something that you need to implement */ \& \& if (key == NULL || key\->expire < t) \& return 0; \& \& HMAC_Init_ex(&hctx, key\->hmac_key, 32, EVP_sha256(), NULL); \& EVP_DecryptInit_ex(&ctx, EVP_aes_256_cbc(), NULL, key\->aes_key, iv); \& \& if (key\->expire < t \- RENEW_TIME) { /* RENEW_TIME: implement */ \& /* \& * return 2 \- This session will get a new ticket even though the \& * current one is still valid. \& */ \& return 2; \& } \& return 1; \& } \& } .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \fBSSL_set_session\fR\|(3), \&\fBSSL_session_reused\fR\|(3), \&\fBSSL_CTX_add_session\fR\|(3), \&\fBSSL_CTX_sess_number\fR\|(3), \&\fBSSL_CTX_sess_set_get_cb\fR\|(3), \&\fBSSL_CTX_set_session_id_context\fR\|(3), .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2014\-2021 The OpenSSL Project Authors.

It verifies a PKCS#7 signedData structure given in \fIp7\fR. The optional \fIcerts\fR parameter refers to a set of certificates in which to search for signer's certificates. \&\fIp7\fR may contain extra untrusted \s-1CA\s0 certificates that may be used for chain building as well as CRLs that may be used for certificate validation. \&\fIstore\fR may be \s-1NULL\s0 or point to the trusted certificate store to use for chain verification. \&\fIindata\fR refers to the signed data if the content is detached from \fIp7\fR. Otherwise \fIindata\fR should be \s-1NULL,\s0 and then the signed data must be in \fIp7\fR. The content is written to the \s-1BIO\s0 \fIout\fR unless it is \s-1NULL.\s0 \&\fIflags\fR is an optional set of flags, which can be used to modify the operation. .PP \&\fBPKCS7_get0_signers()\fR retrieves the signer's certificates from \fIp7\fR, it does \&\fBnot\fR check their validity or whether any signatures are valid. The \fIcerts\fR and \fIflags\fR parameters have the same meanings as in \fBPKCS7_verify()\fR. .SH "VERIFY PROCESS" .IX Header "VERIFY PROCESS" Normally the verify process proceeds as follows. .PP Initially some sanity checks are performed on \fIp7\fR. The type of \fIp7\fR must be SignedData. There must be at least one signature on the data and if the content is detached \fIindata\fR cannot be \s-1NULL.\s0 If the content is not detached and \fIindata\fR is not \s-1NULL\s0 then the structure has both embedded and external content. To treat this as an error, use the flag \&\fB\s-1PKCS7_NO_DUAL_CONTENT\s0\fR. The default behavior allows this, for compatibility with older versions of OpenSSL. .PP An attempt is made to locate all the signer's certificates, first looking in the \fIcerts\fR parameter (if it is not \s-1NULL\s0). Then they are looked up in any certificates contained in the \fIp7\fR structure unless \fB\s-1PKCS7_NOINTERN\s0\fR is set. If any signer's certificates cannot be located the operation fails. .PP Each signer's certificate is chain verified using the \fBsmimesign\fR purpose and using the trusted certificate store \fIstore\fR if supplied. Any internal certificates in the message, which may have been added using \&\fBPKCS7_add_certificate\fR\|(3), are used as untrusted CAs unless \fB\s-1PKCS7_NOCHAIN\s0\fR is set. If \s-1CRL\s0 checking is enabled in \fIstore\fR and \fB\s-1PKCS7_NOCRL\s0\fR is not set, any internal CRLs, which may have been added using \fBPKCS7_add_crl\fR\|(3), are used in addition to attempting to look them up in \fIstore\fR. If \fIstore\fR is not \s-1NULL\s0 and any chain verify fails an error code is returned. .PP Finally the signed content is read (and written to \fIout\fR unless it is \s-1NULL\s0) and the signature is checked. .PP If all signatures verify correctly then the function is successful. .PP Any of the following flags (ored together) can be passed in the \fIflags\fR parameter to change the default verify behaviour. Only the flag \fB\s-1PKCS7_NOINTERN\s0\fR is meaningful to \fBPKCS7_get0_signers()\fR. .PP If \fB\s-1PKCS7_NOINTERN\s0\fR is set the certificates in the message itself are not searched when locating the signer's certificates. This means that all the signer's certificates must be in the \fIcerts\fR parameter. .PP If \fB\s-1PKCS7_NOCRL\s0\fR is set and \s-1CRL\s0 checking is enabled in \fIstore\fR then any CRLs in the message itself are ignored. .PP If the \fB\s-1PKCS7_TEXT\s0\fR flag is set \s-1MIME\s0 headers for type \f(CW\*(C`text/plain\*(C'\fR are deleted from the content. If the content is not of type \f(CW\*(C`text/plain\*(C'\fR then an error is returned. .PP If \fB\s-1PKCS7_NOVERIFY\s0\fR is set the signer's certificates are not chain verified. .PP If \fB\s-1PKCS7_NOCHAIN\s0\fR is set then the certificates contained in the message are not used as untrusted CAs. This means that the whole verify chain (apart from the signer's certificates) must be contained in the trusted store. .PP If \fB\s-1PKCS7_NOSIGS\s0\fR is set then the signatures on the data are not checked. .SH "NOTES" .IX Header "NOTES" One application of \fB\s-1PKCS7_NOINTERN\s0\fR is to only accept messages signed by a small number of certificates. The acceptable certificates would be passed in the \fIcerts\fR parameter. In this case if the signer's certificate is not one of the certificates supplied in \fIcerts\fR then the verify will fail because the signer cannot be found. .PP Care should be taken when modifying the default verify behaviour, for example setting \fBPKCS7_NOVERIFY|PKCS7_NOSIGS\fR will totally disable all verification and any signed message will be considered valid. This combination is however useful if one merely wishes to write the content to \fIout\fR and its validity is not considered important. .PP Chain verification should arguably be performed using the signing time rather than the current time. However, since the signing time is supplied by the signer it cannot be trusted without additional evidence (such as a trusted timestamp). .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBPKCS7_verify()\fR returns 1 for a successful verification and 0 if an error occurs. .PP \&\fBPKCS7_get0_signers()\fR returns all signers or \s-1NULL\s0 if an error occurred. .PP The error can be obtained from \fBERR_get_error\fR\|(3). .SH "BUGS" .IX Header "BUGS" The trusted certificate store is not searched for the signer's certificates. This is primarily due to the inadequacies of the current \fBX509_STORE\fR functionality. .PP The lack of single pass processing means that the signed content must all be held in memory if it is not detached. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBCMS_verify\fR\|(3), \fBPKCS7_add_certificate\fR\|(3), \fBPKCS7_add_crl\fR\|(3), \&\fBERR_get_error\fR\|(3), \fBPKCS7_sign\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2002\-2022 The OpenSSL Project Authors.

Any existing secret value is replaced and any seed is reset. .PP \&\fBEVP_PKEY_CTX_add1_tls1_prf_seed()\fR sets the seed to \fBseedlen\fR bytes of \fBseed\fR.

The \fBtype\fR parameter \*(L"md\*(R" uses the supplied \fBvalue\fR as the name of the digest algorithm to use. The \fBtype\fR parameters \*(L"secret\*(R" and \*(L"seed\*(R" use the supplied \fBvalue\fR parameter as a secret or seed value. The names \*(L"hexsecret\*(R" and \*(L"hexseed\*(R" are similar except they take a hex string which is converted to binary. .SH "NOTES" .IX Header "NOTES" All these functions are implemented as macros. .PP A context for the \s-1TLS PRF\s0 can be obtained by calling: .PP .Vb 1 \& EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_TLS1_PRF, NULL); .Ve .PP The digest, secret value and seed must be set before a key is derived or an error occurs. .PP The total length of all seeds cannot exceed 1024 bytes in length: this should be more than enough for any normal use of the \s-1TLS PRF.\s0 .PP The output length of the \s-1PRF\s0 is specified by the length parameter in the \&\fBEVP_PKEY_derive()\fR function.

Any or all of these parameters can be \fB\s-1NULL\s0\fR, see \fB\s-1NOTES\s0\fR below. .PP The data to be signed is read from \s-1BIO\s0 \fBdata\fR. .PP \&\fBflags\fR is an optional set of flags. .SH "NOTES" .IX Header "NOTES" Any of the following flags (ored together) can be passed in the \fBflags\fR parameter. .PP Many S/MIME clients expect the signed content to include valid \s-1MIME\s0 headers. If the \fB\s-1CMS_TEXT\s0\fR flag is set \s-1MIME\s0 headers for type \fBtext/plain\fR are prepended to the data. .PP If \fB\s-1CMS_NOCERTS\s0\fR is set the signer's certificate will not be included in the CMS_ContentInfo structure, the signer's certificate must still be supplied in the \fBsigncert\fR parameter though. This can reduce the size of the signature if the signers certificate can be obtained by other means: for example a previously signed message. .PP The data being signed is included in the CMS_ContentInfo structure, unless \&\fB\s-1CMS_DETACHED\s0\fR is set in which case it is omitted. This is used for CMS_ContentInfo detached signatures which are used in S/MIME plaintext signed messages for example. .PP Normally the supplied content is translated into \s-1MIME\s0 canonical format (as required by the S/MIME specifications) if \fB\s-1CMS_BINARY\s0\fR is set no translation occurs. This option should be used if the supplied data is in binary format otherwise the translation will corrupt it. .PP The SignedData structure includes several \s-1CMS\s0 signedAttributes including the signing time, the \s-1CMS\s0 content type and the supported list of ciphers in an SMIMECapabilities attribute. If \fB\s-1CMS_NOATTR\s0\fR is set then no signedAttributes will be used. If \fB\s-1CMS_NOSMIMECAP\s0\fR is set then just the SMIMECapabilities are omitted. .PP If present the SMIMECapabilities attribute indicates support for the following algorithms in preference order: 256 bit \s-1AES,\s0 Gost R3411\-94, Gost 28147\-89, 192 bit \s-1AES, 128\s0 bit \s-1AES,\s0 triple \s-1DES, 128\s0 bit \s-1RC2, 64\s0 bit \s-1RC2, DES\s0 and 40 bit \s-1RC2.\s0 If any of these algorithms is not available then it will not be included: for example the \s-1GOST\s0 algorithms will not be included if the \s-1GOST ENGINE\s0 is not loaded. .PP OpenSSL will by default identify signing certificates using issuer name and serial number. If \fB\s-1CMS_USE_KEYID\s0\fR is set it will use the subject key identifier value instead. An error occurs if the signing certificate does not have a subject key identifier extension. .PP If the flags \fB\s-1CMS_STREAM\s0\fR is set then the returned \fBCMS_ContentInfo\fR structure is just initialized ready to perform the signing operation. The signing is however \fBnot\fR performed and the data to be signed is not read from the \fBdata\fR parameter. Signing is deferred until after the data has been written. In this way data can be signed in a single pass. .PP If the \fB\s-1CMS_PARTIAL\s0\fR flag is set a partial \fBCMS_ContentInfo\fR structure is output to which additional signers and capabilities can be added before finalization. .PP If the flag \fB\s-1CMS_STREAM\s0\fR is set the returned \fBCMS_ContentInfo\fR structure is \&\fBnot\fR complete and outputting its contents via a function that does not properly finalize the \fBCMS_ContentInfo\fR structure will give unpredictable results. .PP Several functions including \fBSMIME_write_CMS()\fR, \fBi2d_CMS_bio_stream()\fR, \&\fBPEM_write_bio_CMS_stream()\fR finalize the structure. Alternatively finalization can be performed by obtaining the streaming \s-1ASN1\s0 \fB\s-1BIO\s0\fR directly using \&\fBBIO_new_CMS()\fR. .PP If a signer is specified it will use the default digest for the signing algorithm. This is \fB\s-1SHA1\s0\fR for both \s-1RSA\s0 and \s-1DSA\s0 keys. .PP If \fBsigncert\fR and \fBpkey\fR are \s-1NULL\s0 then a certificates only \s-1CMS\s0 structure is output. .PP The function \fBCMS_sign()\fR is a basic \s-1CMS\s0 signing function whose output will be suitable for many purposes. For finer control of the output format the \&\fBcerts\fR, \fBsigncert\fR and \fBpkey\fR parameters can all be \fB\s-1NULL\s0\fR and the \&\fB\s-1CMS_PARTIAL\s0\fR flag set. Then one or more signers can be added using the function \fBCMS_add1_signer()\fR, non default digests can be used and custom attributes added. \fBCMS_final()\fR must then be called to finalize the structure if streaming is not enabled. .SH "BUGS" .IX Header "BUGS" Some attributes such as counter signatures are not supported. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBCMS_sign()\fR returns either a valid CMS_ContentInfo structure or \s-1NULL\s0 if an error occurred.

Additionally some resources are allocated on a per thread basis (if the application is multi-threaded), and these resources must be freed prior to the thread closing. .PP As of version 1.1.0 OpenSSL will automatically allocate all resources that it needs so no explicit initialisation is required. Similarly it will also automatically deinitialise as required. .PP However, there may be situations when explicit initialisation is desirable or needed, for example when some nondefault initialisation is required. The function \fBOPENSSL_init_ssl()\fR can be used for this purpose. Calling this function will explicitly initialise \s-1BOTH\s0 libcrypto and libssl. To explicitly initialise \s-1ONLY\s0 libcrypto see the \&\fBOPENSSL_init_crypto\fR\|(3) function. .PP Numerous internal OpenSSL functions call \fBOPENSSL_init_ssl()\fR. Therefore, in order to perform nondefault initialisation, \&\fBOPENSSL_init_ssl()\fR \s-1MUST\s0 be called by application code prior to any other OpenSSL function calls. .PP The \fBopts\fR parameter specifies which aspects of libssl and libcrypto should be initialised. Valid options for libcrypto are described on the \&\fBOPENSSL_init_crypto\fR\|(3) page. In addition to any libcrypto specific option the following libssl options can also be used: .IP "\s-1OPENSSL_INIT_NO_LOAD_SSL_STRINGS\s0" 4 .IX Item "OPENSSL_INIT_NO_LOAD_SSL_STRINGS" Suppress automatic loading of the libssl error strings.

Once selected subsequent calls to \&\fBOPENSSL_init_ssl()\fR with the option \&\fB\s-1OPENSSL_INIT_LOAD_SSL_STRINGS\s0\fR will be ignored. .PP \&\fBOPENSSL_init_ssl()\fR takes a \fBsettings\fR parameter which can be used to set parameter values.

The communication channel must already have been set and assigned to the \fBssl\fR by setting an underlying \fB\s-1BIO\s0\fR. .SH "NOTES" .IX Header "NOTES" The behaviour of \fBSSL_connect()\fR depends on the underlying \s-1BIO.\s0 .PP If the underlying \s-1BIO\s0 is \fBblocking\fR, \fBSSL_connect()\fR will only return once the handshake has been finished or an error occurred. .PP If the underlying \s-1BIO\s0 is \fBnonblocking\fR, \fBSSL_connect()\fR will also return when the underlying \s-1BIO\s0 could not satisfy the needs of \fBSSL_connect()\fR to continue the handshake, indicating the problem by the return value \-1. In this case a call to \fBSSL_get_error()\fR with the return value of \fBSSL_connect()\fR will yield \fB\s-1SSL_ERROR_WANT_READ\s0\fR or \&\fB\s-1SSL_ERROR_WANT_WRITE\s0\fR. The calling process then must repeat the call after taking appropriate action to satisfy the needs of \fBSSL_connect()\fR. The action depends on the underlying \s-1BIO.\s0 When using a nonblocking socket, nothing is to be done, but \fBselect()\fR can be used to check for the required condition. When using a buffering \s-1BIO,\s0 like a \s-1BIO\s0 pair, data must be written into or retrieved out of the \s-1BIO\s0 before being able to continue. .PP Many systems implement Nagle's algorithm by default which means that it will buffer outgoing \s-1TCP\s0 data if a \s-1TCP\s0 packet has already been sent for which no corresponding \s-1ACK\s0 has been received yet from the peer. This can have performance impacts after a successful TLSv1.3 handshake or a successful TLSv1.2 (or below) resumption handshake, because the last peer to communicate in the handshake is the client. If the client is also the first to send application data (as is typical for many protocols) then this data could be buffered until an \s-1ACK\s0 has been received for the final handshake message. .PP The \fB\s-1TCP_NODELAY\s0\fR socket option is often available to disable Nagle's algorithm. If an application opts to disable Nagle's algorithm consideration should be given to turning it back on again later if appropriate. The helper function \fBBIO_set_tcp_ndelay()\fR can be used to turn on or off the \fB\s-1TCP_NODELAY\s0\fR option. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The following return values can occur: .IP "0" 4 The \s-1TLS/SSL\s0 handshake was not successful but was shut down controlled and by the specifications of the \s-1TLS/SSL\s0 protocol. Call \fBSSL_get_error()\fR with the return value \fBret\fR to find out the reason. .IP "1" 4 .IX Item "1" The \s-1TLS/SSL\s0 handshake was successfully completed, a \s-1TLS/SSL\s0 connection has been established. .IP "<0" 4 .IX Item "<0" The \s-1TLS/SSL\s0 handshake was not successful, because a fatal error occurred either at the protocol level or a connection failure occurred. The shutdown was not clean. It can also occur if action is needed to continue the operation for nonblocking BIOs.

It is used for the OpenSSL master configuration file \fBopenssl.cnf\fR and in a few other places like \fB\s-1SPKAC\s0\fR files and certificate extension files for the \fBx509\fR utility. OpenSSL applications can also use the \&\s-1CONF\s0 library for their own purposes. .PP A configuration file is divided into a number of sections. Each section starts with a line \fB[ section_name ]\fR and ends when a new section is started or end of file is reached. A section name can consist of alphanumeric characters and underscores. .PP The first section of a configuration file is special and is referred to as the \fBdefault\fR section. This section is usually unnamed and spans from the start of file until the first named section. When a name is being looked up it is first looked up in a named section (if any) and then the default section. .PP The environment is mapped onto a section called \fB\s-1ENV\s0\fR. .PP Comments can be included by preceding them with the \fB#\fR character .PP Other files can be included using the \fB.include\fR directive followed by a path. If the path points to a directory all files with names ending with \fB.cnf\fR or \fB.conf\fR are included from the directory. Recursive inclusion of directories from files in such directory is not supported. That means the files in the included directory can also contain \&\fB.include\fR directives but only inclusion of regular files is supported there. The inclusion of directories is not supported on systems without \&\s-1POSIX IO\s0 support. .PP It is strongly recommended to use absolute paths with the \fB.include\fR directive. Relative paths are evaluated based on the application current working directory so unless the configuration file containing the \&\fB.include\fR directive is application specific the inclusion will not work as expected. .PP There can be optional \fB=\fR character and whitespace characters between \&\fB.include\fR directive and the path which can be useful in cases the configuration file needs to be loaded by old OpenSSL versions which do not support the \fB.include\fR syntax. They would bail out with error if the \fB=\fR character is not present but with it they just ignore the include. .PP Each section in a configuration file consists of a number of name and value pairs of the form \fBname=value\fR .PP The \fBname\fR string can contain any alphanumeric characters as well as a few punctuation symbols such as \fB.\fR \fB,\fR \fB;\fR and \fB_\fR. .PP The \fBvalue\fR string consists of the string following the \fB=\fR character until end of line with any leading and trailing white space removed. .PP The value string undergoes variable expansion. This can be done by including the form \fB\f(CB$var\fB\fR or \fB${var}\fR: this will substitute the value of the named variable in the current section. It is also possible to substitute a value from another section using the syntax \fB\f(CB$section::name\fB\fR or \fB${section::name}\fR. By using the form \fB\f(CB$ENV::name\fB\fR environment variables can be substituted. It is also possible to assign values to environment variables by using the name \fBENV::name\fR, this will work if the program looks up environment variables using the \fB\s-1CONF\s0\fR library instead of calling \fBgetenv()\fR directly. The value string must not exceed 64k in length after variable expansion. Otherwise an error will occur. .PP It is possible to escape certain characters by using any kind of quote or the \fB\e\fR character. By making the last character of a line a \fB\e\fR a \fBvalue\fR string can be spread across multiple lines. In addition the sequences \fB\en\fR, \fB\er\fR, \fB\eb\fR and \fB\et\fR are recognized. .PP All expansion and escape rules as described above that apply to \fBvalue\fR also apply to the path of the \fB.include\fR directive. .SH "OPENSSL LIBRARY CONFIGURATION" .IX Header "OPENSSL LIBRARY CONFIGURATION" Applications can automatically configure certain aspects of OpenSSL using the master OpenSSL configuration file, or optionally an alternative configuration file. The \fBopenssl\fR utility includes this functionality: any sub command uses the master OpenSSL configuration file unless an option is used in the sub command to use an alternative configuration file. .PP To enable library configuration the default section needs to contain an appropriate line which points to the main configuration section. The default name is \fBopenssl_conf\fR which is used by the \fBopenssl\fR utility. Other applications may use an alternative name such as \fBmyapplication_conf\fR. All library configuration lines appear in the default section at the start of the configuration file. .PP The configuration section should consist of a set of name value pairs which contain specific module configuration information. The \fBname\fR represents the name of the \fIconfiguration module\fR. The meaning of the \fBvalue\fR is module specific: it may, for example, represent a further configuration section containing configuration module specific information. E.g.: .PP .Vb 2 \& # This must be in the default section \& openssl_conf = openssl_init \& \& [openssl_init] \& \& oid_section = new_oids \& engines = engine_section \& \& [new_oids] \& \& ... new oids here ... \& \& [engine_section] \& \& ... engine stuff here ... .Ve .PP The features of each configuration module are described below. .SS "\s-1ASN1\s0 Object Configuration Module" .IX Subsection "ASN1 Object Configuration Module" This module has the name \fBoid_section\fR. The value of this variable points to a section containing name value pairs of OIDs: the name is the \s-1OID\s0 short and long name, the value is the numerical form of the \s-1OID.\s0 Although some of the \fBopenssl\fR utility sub commands already have their own \s-1ASN1 OBJECT\s0 section functionality not all do. By using the \s-1ASN1 OBJECT\s0 configuration module \&\fBall\fR the \fBopenssl\fR utility sub commands can see the new objects as well as any compliant applications. For example: .PP .Vb 1 \& [new_oids] \& \& some_new_oid = 1.2.3.4 \& some_other_oid = 1.2.3.5 .Ve .PP It is also possible to set the value to the long name followed by a comma and the numerical \s-1OID\s0 form. For example: .PP .Vb 1 \& shortName = some object long name, 1.2.3.4 .Ve .SS "Engine Configuration Module" .IX Subsection "Engine Configuration Module" This \s-1ENGINE\s0 configuration module has the name \fBengines\fR. The value of this variable points to a section containing further \s-1ENGINE\s0 configuration information. .PP The section pointed to by \fBengines\fR is a table of engine names (though see \&\fBengine_id\fR below) and further sections containing configuration information specific to each \s-1ENGINE.\s0 .PP Each \s-1ENGINE\s0 specific section is used to set default algorithms, load dynamic, perform initialization and send ctrls. The actual operation performed depends on the \fIcommand\fR name which is the name of the name value pair. The currently supported commands are listed below. .PP For example: .PP .Vb 1 \& [engine_section] \& \& # Configure ENGINE named "foo" \& foo = foo_section \& # Configure ENGINE named "bar" \& bar = bar_section \& \& [foo_section] \& ... foo ENGINE specific commands ... \& \& [bar_section] \& ... "bar" ENGINE specific commands ... .Ve .PP The command \fBengine_id\fR is used to give the \s-1ENGINE\s0 name. If used this command must be first. For example: .PP .Vb 3 \& [engine_section] \& # This would normally handle an ENGINE named "foo" \& foo = foo_section \& \& [foo_section] \& # Override default name and use "myfoo" instead. \& engine_id = myfoo .Ve .PP The command \fBdynamic_path\fR loads and adds an \s-1ENGINE\s0 from the given path. It is equivalent to sending the ctrls \fB\s-1SO_PATH\s0\fR with the path argument followed by \fB\s-1LIST_ADD\s0\fR with value 2 and \fB\s-1LOAD\s0\fR to the dynamic \s-1ENGINE.\s0 If this is not the required behaviour then alternative ctrls can be sent directly to the dynamic \s-1ENGINE\s0 using ctrl commands. .PP The command \fBinit\fR determines whether to initialize the \s-1ENGINE.\s0 If the value is \fB0\fR the \s-1ENGINE\s0 will not be initialized, if \fB1\fR and attempt it made to initialized the \s-1ENGINE\s0 immediately. If the \fBinit\fR command is not present then an attempt will be made to initialize the \s-1ENGINE\s0 after all commands in its section have been processed. .PP The command \fBdefault_algorithms\fR sets the default algorithms an \s-1ENGINE\s0 will supply using the functions \fBENGINE_set_default_string()\fR. .PP If the name matches none of the above command names it is assumed to be a ctrl command which is sent to the \s-1ENGINE.\s0 The value of the command is the argument to the ctrl command. If the value is the string \fB\s-1EMPTY\s0\fR then no value is sent to the command. .PP For example: .PP .Vb 1 \& [engine_section] \& \& # Configure ENGINE named "foo" \& foo = foo_section \& \& [foo_section] \& # Load engine from DSO \& dynamic_path = /some/path/fooengine.so \& # A foo specific ctrl. \& some_ctrl = some_value \& # Another ctrl that doesn\*(Aqt take a value. \& other_ctrl = EMPTY \& # Supply all default algorithms \& default_algorithms = ALL .Ve .SS "\s-1EVP\s0 Configuration Module" .IX Subsection "EVP Configuration Module" This modules has the name \fBalg_section\fR which points to a section containing algorithm commands. .PP Currently the only algorithm command supported is \fBfips_mode\fR whose value can only be the boolean string \fBoff\fR. If \fBfips_mode\fR is set to \fBon\fR, an error occurs as this library version is not \s-1FIPS\s0 capable. .SS "\s-1SSL\s0 Configuration Module" .IX Subsection "SSL Configuration Module" This module has the name \fBssl_conf\fR which points to a section containing \&\s-1SSL\s0 configurations. .PP Each line in the \s-1SSL\s0 configuration section contains the name of the configuration and the section containing it. .PP Each configuration section consists of command value pairs for \fB\s-1SSL_CONF\s0\fR. Each pair will be passed to a \fB\s-1SSL_CTX\s0\fR or \fB\s-1SSL\s0\fR structure if it calls \&\fBSSL_CTX_config()\fR or \fBSSL_config()\fR with the appropriate configuration name. .PP Note: any characters before an initial dot in the configuration section are ignored so the same command can be used multiple times. .PP For example: .PP .Vb 1 \& ssl_conf = ssl_sect \& \& [ssl_sect] \& \& server = server_section \& \& [server_section] \& \& RSA.Certificate = server\-rsa.pem \& ECDSA.Certificate = server\-ecdsa.pem \& Ciphers = ALL:!RC4 .Ve .PP The system default configuration with name \fBsystem_default\fR if present will be applied during any creation of the \fB\s-1SSL_CTX\s0\fR structure. .PP Example of a configuration with the system default: .PP .Vb 1 \& ssl_conf = ssl_sect \& \& [ssl_sect] \& system_default = system_default_sect \& \& [system_default_sect] \& MinProtocol = TLSv1.2 \& MinProtocol = DTLSv1.2 .Ve .SH "NOTES" .IX Header "NOTES" If a configuration file attempts to expand a variable that doesn't exist then an error is flagged and the file will not load. This can happen if an attempt is made to expand an environment variable that doesn't exist. For example in a previous version of OpenSSL the default OpenSSL master configuration file used the value of \fB\s-1HOME\s0\fR which may not be defined on non Unix systems and would cause an error. .PP This can be worked around by including a \fBdefault\fR section to provide a default value: then if the environment lookup fails the default value will be used instead. For this to work properly the default value must be defined earlier in the configuration file than the expansion. See the \fB\s-1EXAMPLES\s0\fR section for an example of how to do this. .PP If the same variable exists in the same section then all but the last value will be silently ignored. In certain circumstances such as with DNs the same field may occur multiple times. This is usually worked around by ignoring any characters before an initial \fB.\fR e.g. .PP .Vb 2 \& 1.OU="My first OU" \& 2.OU="My Second OU" .Ve .SH "EXAMPLES" .IX Header "EXAMPLES" Here is a sample configuration file using some of the features mentioned above. .PP .Vb 1 \& # This is the default section. \& \& HOME=/temp \& RANDFILE= ${ENV::HOME}/.rnd \& configdir=$ENV::HOME/config \& \& [ section_one ] \& \& # We are now in section one. \& \& # Quotes permit leading and trailing whitespace \& any = " any variable name " \& \& other = A string that can \e \& cover several lines \e \& by including \e\e characters \& \& message = Hello World\en \& \& [ section_two ] \& \& greeting = $section_one::message .Ve .PP This next example shows how to expand environment variables safely. .PP Suppose you want a variable called \fBtmpfile\fR to refer to a temporary filename. The directory it is placed in can determined by the \fB\s-1TEMP\s0\fR or \fB\s-1TMP\s0\fR environment variables but they may not be set to any value at all. If you just include the environment variable names and the variable doesn't exist then this will cause an error when an attempt is made to load the configuration file.

Each line of the extension section takes the form: .PP .Vb 1 \& extension_name=[critical,] extension_options .Ve .PP If \fBcritical\fR is present then the extension will be critical. .PP The format of \fBextension_options\fR depends on the value of \fBextension_name\fR. .PP There are four main types of extension: \fIstring\fR extensions, \fImulti-valued\fR extensions, \fIraw\fR and \fIarbitrary\fR extensions. .PP String extensions simply have a string which contains either the value itself or how it is obtained. .PP For example: .PP .Vb 1 \& nsComment="This is a Comment" .Ve .PP Multi-valued extensions have a short form and a long form. The short form is a list of names and values: .PP .Vb 1 \& basicConstraints=critical,CA:true,pathlen:1 .Ve .PP The long form allows the values to be placed in a separate section: .PP .Vb 1 \& basicConstraints=critical,@bs_section \& \& [bs_section] \& \& CA=true \& pathlen=1 .Ve .PP Both forms are equivalent. .PP The syntax of raw extensions is governed by the extension code: it can for example contain data in multiple sections. The correct syntax to use is defined by the extension code itself: check out the certificate policies extension for an example. .PP If an extension type is unsupported then the \fIarbitrary\fR extension syntax must be used, see the \s-1ARBITRARY EXTENSIONS\s0 section for more details. .SH "STANDARD EXTENSIONS" .IX Header "STANDARD EXTENSIONS" The following sections describe each supported extension in detail. .SS "Basic Constraints." .IX Subsection "Basic Constraints." This is a multi valued extension which indicates whether a certificate is a \s-1CA\s0 certificate. The first (mandatory) name is \fB\s-1CA\s0\fR followed by \fB\s-1TRUE\s0\fR or \&\fB\s-1FALSE\s0\fR. If \fB\s-1CA\s0\fR is \fB\s-1TRUE\s0\fR then an optional \fBpathlen\fR name followed by a nonnegative value can be included. .PP For example: .PP .Vb 1 \& basicConstraints=CA:TRUE \& \& basicConstraints=CA:FALSE \& \& basicConstraints=critical,CA:TRUE, pathlen:0 .Ve .PP A \s-1CA\s0 certificate \fBmust\fR include the basicConstraints value with the \s-1CA\s0 field set to \s-1TRUE.\s0 An end user certificate must either set \s-1CA\s0 to \s-1FALSE\s0 or exclude the extension entirely. Some software may require the inclusion of basicConstraints with \s-1CA\s0 set to \s-1FALSE\s0 for end entity certificates. .PP The pathlen parameter indicates the maximum number of CAs that can appear below this one in a chain. So if you have a \s-1CA\s0 with a pathlen of zero it can only be used to sign end user certificates and not further CAs. .SS "Key Usage." .IX Subsection "Key Usage." Key usage is a multi valued extension consisting of a list of names of the permitted key usages. .PP The supported names are: digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment, keyAgreement, keyCertSign, cRLSign, encipherOnly and decipherOnly. .PP Examples: .PP .Vb 1 \& keyUsage=digitalSignature, nonRepudiation \& \& keyUsage=critical, keyCertSign .Ve .SS "Extended Key Usage." .IX Subsection "Extended Key Usage." This extensions consists of a list of usages indicating purposes for which the certificate public key can be used for, .PP These can either be object short names or the dotted numerical form of OIDs. While any \s-1OID\s0 can be used only certain values make sense. In particular the following \s-1PKIX, NS\s0 and \s-1MS\s0 values are meaningful: .PP .Vb 10 \& Value Meaning \& \-\-\-\-\- \-\-\-\-\-\-\- \& serverAuth SSL/TLS Web Server Authentication. \& clientAuth SSL/TLS Web Client Authentication. \& codeSigning Code signing. \& emailProtection E\-mail Protection (S/MIME). \& timeStamping Trusted Timestamping \& OCSPSigning OCSP Signing \& ipsecIKE ipsec Internet Key Exchange \& msCodeInd Microsoft Individual Code Signing (authenticode) \& msCodeCom Microsoft Commercial Code Signing (authenticode) \& msCTLSign Microsoft Trust List Signing \& msEFS Microsoft Encrypted File System .Ve .PP Examples: .PP .Vb 2 \& extendedKeyUsage=critical,codeSigning,1.2.3.4 \& extendedKeyUsage=serverAuth,clientAuth .Ve .SS "Subject Key Identifier." .IX Subsection "Subject Key Identifier." This is really a string extension and can take two possible values. Either the word \fBhash\fR which will automatically follow the guidelines in \s-1RFC3280\s0 or a hex string giving the extension value to include. The use of the hex string is strongly discouraged. .PP Example: .PP .Vb 1 \& subjectKeyIdentifier=hash .Ve .SS "Authority Key Identifier." .IX Subsection "Authority Key Identifier." The authority key identifier extension permits two options. keyid and issuer: both can take the optional value \*(L"always\*(R". .PP If the keyid option is present an attempt is made to copy the subject key identifier from the parent certificate. If the value \*(L"always\*(R" is present then an error is returned if the option fails. .PP The issuer option copies the issuer and serial number from the issuer certificate. This will only be done if the keyid option fails or is not included unless the \*(L"always\*(R" flag will always include the value. .PP Example: .PP .Vb 1 \& authorityKeyIdentifier=keyid,issuer .Ve .SS "Subject Alternative Name." .IX Subsection "Subject Alternative Name." The subject alternative name extension allows various literal values to be included in the configuration file. These include \fBemail\fR (an email address) \&\fB\s-1URI\s0\fR a uniform resource indicator, \fB\s-1DNS\s0\fR (a \s-1DNS\s0 domain name), \fB\s-1RID\s0\fR (a registered \s-1ID: OBJECT IDENTIFIER\s0), \fB\s-1IP\s0\fR (an \s-1IP\s0 address), \fBdirName\fR (a distinguished name) and otherName. .PP The email option include a special 'copy' value. This will automatically include any email addresses contained in the certificate subject name in the extension. .PP The \s-1IP\s0 address used in the \fB\s-1IP\s0\fR options can be in either IPv4 or IPv6 format. .PP The value of \fBdirName\fR should point to a section containing the distinguished name to use as a set of name value pairs. Multi values AVAs can be formed by prefacing the name with a \fB+\fR character. .PP otherName can include arbitrary data associated with an \s-1OID:\s0 the value should be the \s-1OID\s0 followed by a semicolon and the content in standard \&\fBASN1_generate_nconf\fR\|(3) format. .PP Examples: .PP .Vb 5 \& subjectAltName=email:copy,email:my@other.address,URI:http://my.url.here/ \& subjectAltName=IP:192.168.7.1 \& subjectAltName=IP:13::17 \& subjectAltName=email:my@other.address,RID:1.2.3.4 \& subjectAltName=otherName:1.2.3.4;UTF8:some other identifier \& \& subjectAltName=dirName:dir_sect \& \& [dir_sect] \& C=UK \& O=My Organization \& OU=My Unit \& CN=My Name .Ve .SS "Issuer Alternative Name." .IX Subsection "Issuer Alternative Name." The issuer alternative name option supports all the literal options of subject alternative name. It does \fBnot\fR support the email:copy option because that would not make sense. It does support an additional issuer:copy option that will copy all the subject alternative name values from the issuer certificate (if possible). .PP Example: .PP .Vb 1 \& issuerAltName = issuer:copy .Ve .SS "Authority Info Access." .IX Subsection "Authority Info Access." The authority information access extension gives details about how to access certain information relating to the \s-1CA.\s0 Its syntax is accessOID;location where \fIlocation\fR has the same syntax as subject alternative name (except that email:copy is not supported). accessOID can be any valid \s-1OID\s0 but only certain values are meaningful, for example \s-1OCSP\s0 and caIssuers. .PP Example: .PP .Vb 2 \& authorityInfoAccess = OCSP;URI:http://ocsp.my.host/ \& authorityInfoAccess = caIssuers;URI:http://my.ca/ca.html .Ve .SS "\s-1CRL\s0 distribution points" .IX Subsection "CRL distribution points" This is a multi-valued extension whose options can be either in name:value pair using the same form as subject alternative name or a single value representing a section name containing all the distribution point fields. .PP For a name:value pair a new DistributionPoint with the fullName field set to the given value both the cRLissuer and reasons fields are omitted in this case. .PP In the single option case the section indicated contains values for each field. In this section: .PP If the name is \*(L"fullname\*(R" the value field should contain the full name of the distribution point in the same format as subject alternative name. .PP If the name is \*(L"relativename\*(R" then the value field should contain a section name whose contents represent a \s-1DN\s0 fragment to be placed in this field. .PP The name \*(L"CRLIssuer\*(R" if present should contain a value for this field in subject alternative name format. .PP If the name is \*(L"reasons\*(R" the value field should consist of a comma separated field containing the reasons. Valid reasons are: \*(L"keyCompromise\*(R", \&\*(L"CACompromise\*(R", \*(L"affiliationChanged\*(R", \*(L"superseded\*(R", \*(L"cessationOfOperation\*(R", \&\*(L"certificateHold\*(R", \*(L"privilegeWithdrawn\*(R" and \*(L"AACompromise\*(R". .PP Simple examples: .PP .Vb 2 \& crlDistributionPoints=URI:http://myhost.com/myca.crl \& crlDistributionPoints=URI:http://my.com/my.crl,URI:http://oth.com/my.crl .Ve .PP Full distribution point example: .PP .Vb 1 \& crlDistributionPoints=crldp1_section \& \& [crldp1_section] \& \& fullname=URI:http://myhost.com/myca.crl \& CRLissuer=dirName:issuer_sect \& reasons=keyCompromise, CACompromise \& \& [issuer_sect] \& C=UK \& O=Organisation \& CN=Some Name .Ve .SS "Issuing Distribution Point" .IX Subsection "Issuing Distribution Point" This extension should only appear in CRLs. It is a multi valued extension whose syntax is similar to the \*(L"section\*(R" pointed to by the \s-1CRL\s0 distribution points extension with a few differences. .PP The names \*(L"reasons\*(R" and \*(L"CRLissuer\*(R" are not recognized. .PP The name \*(L"onlysomereasons\*(R" is accepted which sets this field. The value is in the same format as the \s-1CRL\s0 distribution point \*(L"reasons\*(R" field. .PP The names \*(L"onlyuser\*(R", \*(L"onlyCA\*(R", \*(L"onlyAA\*(R" and \*(L"indirectCRL\*(R" are also accepted the values should be a boolean value (\s-1TRUE\s0 or \s-1FALSE\s0) to indicate the value of the corresponding field. .PP Example: .PP .Vb 1 \& issuingDistributionPoint=critical, @idp_section \& \& [idp_section] \& \& fullname=URI:http://myhost.com/myca.crl \& indirectCRL=TRUE \& onlysomereasons=keyCompromise, CACompromise \& \& [issuer_sect] \& C=UK \& O=Organisation \& CN=Some Name .Ve .SS "Certificate Policies." .IX Subsection "Certificate Policies." This is a \fIraw\fR extension. All the fields of this extension can be set by using the appropriate syntax. .PP If you follow the \s-1PKIX\s0 recommendations and just using one \s-1OID\s0 then you just include the value of that \s-1OID.\s0 Multiple OIDs can be set separated by commas, for example: .PP .Vb 1 \& certificatePolicies= 1.2.4.5, 1.1.3.4 .Ve .PP If you wish to include qualifiers then the policy \s-1OID\s0 and qualifiers need to be specified in a separate section: this is done by using the \f(CW@section\fR syntax instead of a literal \s-1OID\s0 value. .PP The section referred to must include the policy \s-1OID\s0 using the name policyIdentifier, cPSuri qualifiers can be included using the syntax: .PP .Vb 1 \& CPS.nnn=value .Ve .PP userNotice qualifiers can be set using the syntax: .PP .Vb 1 \& userNotice.nnn=@notice .Ve .PP The value of the userNotice qualifier is specified in the relevant section. This section can include explicitText, organization and noticeNumbers options. explicitText and organization are text strings, noticeNumbers is a comma separated list of numbers. The organization and noticeNumbers options (if included) must \s-1BOTH\s0 be present. If you use the userNotice option with \s-1IE5\s0 then you need the 'ia5org' option at the top level to modify the encoding: otherwise it will not be interpreted properly. .PP Example: .PP .Vb 1 \& certificatePolicies=ia5org,1.2.3.4,1.5.6.7.8,@polsect \& \& [polsect] \& \& policyIdentifier = 1.3.5.8 \& CPS.1="http://my.host.name/" \& CPS.2="http://my.your.name/" \& userNotice.1=@notice \& \& [notice] \& \& explicitText="Explicit Text Here" \& organization="Organisation Name" \& noticeNumbers=1,2,3,4 .Ve .PP The \fBia5org\fR option changes the type of the \fIorganization\fR field. In \s-1RFC2459\s0 it can only be of type DisplayText. In \s-1RFC3280\s0 IA5String is also permissible. Some software (for example some versions of \s-1MSIE\s0) may require ia5org. .PP \&\s-1ASN1\s0 type of explicitText can be specified by prepending \fB\s-1UTF8\s0\fR, \&\fB\s-1BMP\s0\fR or \fB\s-1VISIBLE\s0\fR prefix followed by colon. For example: .PP .Vb 2 \& [notice] \& explicitText="UTF8:Explicit Text Here" .Ve .SS "Policy Constraints" .IX Subsection "Policy Constraints" This is a multi-valued extension which consisting of the names \&\fBrequireExplicitPolicy\fR or \fBinhibitPolicyMapping\fR and a non negative integer value. At least one component must be present. .PP Example: .PP .Vb 1 \& policyConstraints = requireExplicitPolicy:3 .Ve .SS "Inhibit Any Policy" .IX Subsection "Inhibit Any Policy" This is a string extension whose value must be a non negative integer. .PP Example: .PP .Vb 1 \& inhibitAnyPolicy = 2 .Ve .SS "Name Constraints" .IX Subsection "Name Constraints" The name constraints extension is a multi-valued extension. The name should begin with the word \fBpermitted\fR or \fBexcluded\fR followed by a \fB;\fR. The rest of the name and the value follows the syntax of subjectAltName except email:copy is not supported and the \fB\s-1IP\s0\fR form should consist of an \s-1IP\s0 addresses and subnet mask separated by a \fB/\fR. .PP Examples: .PP .Vb 1 \& nameConstraints=permitted;IP:192.168.0.0/255.255.0.0 \& \& nameConstraints=permitted;email:.somedomain.com \& \& nameConstraints=excluded;email:.com .Ve .SS "\s-1OCSP\s0 No Check" .IX Subsection "OCSP No Check" The \s-1OCSP\s0 No Check extension is a string extension but its value is ignored. .PP Example: .PP .Vb 1 \& noCheck = ignored .Ve .SS "\s-1TLS\s0 Feature (aka Must Staple)" .IX Subsection "TLS Feature (aka Must Staple)" This is a multi-valued extension consisting of a list of \s-1TLS\s0 extension identifiers. Each identifier may be a number (0..65535) or a supported name. When a \s-1TLS\s0 client sends a listed extension, the \s-1TLS\s0 server is expected to include that extension in its reply. .PP The supported names are: \fBstatus_request\fR and \fBstatus_request_v2\fR. .PP Example: .PP .Vb 1 \& tlsfeature = status_request .Ve .SH "DEPRECATED EXTENSIONS" .IX Header "DEPRECATED EXTENSIONS" The following extensions are non standard, Netscape specific and largely obsolete. Their use in new applications is discouraged. .SS "Netscape String extensions." .IX Subsection "Netscape String extensions." Netscape Comment (\fBnsComment\fR) is a string extension containing a comment which will be displayed when the certificate is viewed in some browsers. .PP Example: .PP .Vb 1 \& nsComment = "Some Random Comment" .Ve .PP Other supported extensions in this category are: \fBnsBaseUrl\fR, \&\fBnsRevocationUrl\fR, \fBnsCaRevocationUrl\fR, \fBnsRenewalUrl\fR, \fBnsCaPolicyUrl\fR and \fBnsSslServerName\fR. .SS "Netscape Certificate Type" .IX Subsection "Netscape Certificate Type" This is a multi-valued extensions which consists of a list of flags to be included. It was used to indicate the purposes for which a certificate could be used. The basicConstraints, keyUsage and extended key usage extensions are now used instead. .PP Acceptable values for nsCertType are: \fBclient\fR, \fBserver\fR, \fBemail\fR, \&\fBobjsign\fR, \fBreserved\fR, \fBsslCA\fR, \fBemailCA\fR, \fBobjCA\fR. .SH "ARBITRARY EXTENSIONS" .IX Header "ARBITRARY EXTENSIONS" If an extension is not supported by the OpenSSL code then it must be encoded using the arbitrary extension format. It is also possible to use the arbitrary format for supported extensions. Extreme care should be taken to ensure that the data is formatted correctly for the given extension type. .PP There are two ways to encode arbitrary extensions. .PP The first way is to use the word \s-1ASN1\s0 followed by the extension content using the same syntax as \fBASN1_generate_nconf\fR\|(3). For example: .PP .Vb 1 \& 1.2.3.4=critical,ASN1:UTF8String:Some random data \& \& 1.2.3.4=ASN1:SEQUENCE:seq_sect \& \& [seq_sect] \& \& field1 = UTF8:field1 \& field2 = UTF8:field2 .Ve .PP It is also possible to use the word \s-1DER\s0 to include the raw encoded data in any extension. .PP .Vb 2 \& 1.2.3.4=critical,DER:01:02:03:04 \& 1.2.3.4=DER:01020304 .Ve .PP The value following \s-1DER\s0 is a hex dump of the \s-1DER\s0 encoding of the extension Any extension can be placed in this form to override the default behaviour. For example: .PP .Vb 1 \& basicConstraints=critical,DER:00:01:02:03 .Ve .SH "WARNINGS" .IX Header "WARNINGS" There is no guarantee that a specific implementation will process a given extension. It may therefore be sometimes possible to use certificates for purposes prohibited by their extensions because a specific application does not recognize or honour the values of the relevant extensions. .PP The \s-1DER\s0 and \s-1ASN1\s0 options should be used with caution.

When a password is being specified using one of the other options, the \s-1IV\s0 is generated from this password. .IP "\fB\-p\fR" 4 .IX Item "-p" Print out the key and \s-1IV\s0 used. .IP "\fB\-P\fR" 4 .IX Item "-P" Print out the key and \s-1IV\s0 used then immediately exit: don't do any encryption or decryption. .IP "\fB\-bufsize number\fR" 4 .IX Item "-bufsize number" Set the buffer size for I/O. .IP "\fB\-nopad\fR" 4 .IX Item "-nopad" Disable standard block padding. .IP "\fB\-debug\fR" 4 .IX Item "-debug" Debug the BIOs used for I/O. .IP "\fB\-z\fR" 4 .IX Item "-z" Compress or decompress encrypted data using zlib after encryption or before decryption. This option exists only if OpenSSL was compiled with the zlib or zlib-dynamic option. .IP "\fB\-none\fR" 4 .IX Item "-none" Use \s-1NULL\s0 cipher (no encryption or decryption of input). .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .SH "NOTES" .IX Header "NOTES" The program can be called either as \fBopenssl cipher\fR or \&\fBopenssl enc \-cipher\fR. The first form doesn't work with engine-provided ciphers, because this form is processed before the configuration file is read and any ENGINEs loaded. Use the \fBlist\fR command to get a list of supported ciphers. .PP Engines which provide entirely new encryption algorithms (such as the ccgost engine which provides gost89 algorithm) should be configured in the configuration file. Engines specified on the command line using \-engine options can only be used for hardware-assisted implementations of ciphers which are supported by the OpenSSL core or another engine specified in the configuration file. .PP When the enc command lists supported ciphers, ciphers provided by engines, specified in the configuration files are listed too. .PP A password will be prompted for to derive the key and \s-1IV\s0 if necessary. .PP The \fB\-salt\fR option should \fB\s-1ALWAYS\s0\fR be used if the key is being derived from a password unless you want compatibility with previous versions of OpenSSL. .PP Without the \fB\-salt\fR option it is possible to perform efficient dictionary attacks on the password and to attack stream cipher encrypted data. The reason for this is that without the salt the same password always generates the same encryption key. When the salt is being used the first eight bytes of the encrypted data are reserved for the salt: it is generated at random when encrypting a file and read from the encrypted file when it is decrypted. .PP Some of the ciphers do not have large keys and others have security implications if not used correctly. A beginner is advised to just use a strong block cipher, such as \s-1AES,\s0 in \s-1CBC\s0 mode. .PP All the block ciphers normally use PKCS#5 padding, also known as standard block padding. This allows a rudimentary integrity or password check to be performed. However, since the chance of random data passing the test is better than 1 in 256 it isn't a very good test. .PP If padding is disabled then the input data must be a multiple of the cipher block length. .PP All \s-1RC2\s0 ciphers have the same key and effective key length. .PP Blowfish and \s-1RC5\s0 algorithms use a 128 bit key. .SH "SUPPORTED CIPHERS" .IX Header "SUPPORTED CIPHERS" Note that some of these ciphers can be disabled at compile time and some are available only if an appropriate engine is configured in the configuration file. The output of the \fBenc\fR command run with the \fB\-ciphers\fR option (that is \fBopenssl enc \-ciphers\fR) produces a list of ciphers, supported by your version of OpenSSL, including ones provided by configured engines. .PP The \fBenc\fR program does not support authenticated encryption modes like \s-1CCM\s0 and \s-1GCM,\s0 and will not support such modes in the future. The \fBenc\fR interface by necessity must begin streaming output (e.g., to standard output when \fB\-out\fR is not used) before the authentication tag could be validated, leading to the usage of \fBenc\fR in pipelines that begin processing untrusted data and are not capable of rolling back upon authentication failure. The \s-1AEAD\s0 modes currently in common use also suffer from catastrophic failure of confidentiality and/or integrity upon reuse of key/iv/nonce, and since \fBenc\fR places the entire burden of key/iv/nonce management upon the user, the risk of exposing \s-1AEAD\s0 modes is too great to allow. These key/iv/nonce management issues also affect other modes currently exposed in \fBenc\fR, but the failure modes are less extreme in these cases, and the functionality cannot be removed with a stable release branch. For bulk encryption of data, whether using authenticated encryption modes or other modes, \fBcms\fR\|(1) is recommended, as it provides a standard data format and performs the needed key/iv/nonce management. .PP .Vb 1 \& base64 Base 64 \& \& bf\-cbc Blowfish in CBC mode \& bf Alias for bf\-cbc \& blowfish Alias for bf\-cbc \& bf\-cfb Blowfish in CFB mode \& bf\-ecb Blowfish in ECB mode \&

It can encrypt, decrypt, sign and verify S/MIME messages. .SH "OPTIONS" .IX Header "OPTIONS" There are six operation options that set the type of operation to be performed. The meaning of the other options varies according to the operation type. .IP "\fB\-help\fR" 4 .IX Item "-help" Print out a usage message. .IP "\fB\-encrypt\fR" 4 .IX Item "-encrypt" Encrypt mail for the given recipient certificates. Input file is the message to be encrypted. The output file is the encrypted mail in \s-1MIME\s0 format. .Sp Note that no revocation check is done for the recipient cert, so if that key has been compromised, others may be able to decrypt the text. .IP "\fB\-decrypt\fR" 4 .IX Item "-decrypt" Decrypt mail using the supplied certificate and private key. Expects an encrypted mail message in \s-1MIME\s0 format for the input file. The decrypted mail is written to the output file. .IP "\fB\-sign\fR" 4 .IX Item "-sign" Sign mail using the supplied certificate and private key. Input file is the message to be signed. The signed message in \s-1MIME\s0 format is written to the output file. .IP "\fB\-verify\fR" 4 .IX Item "-verify" Verify signed mail. Expects a signed mail message on input and outputs the signed data. Both clear text and opaque signing is supported. .IP "\fB\-pk7out\fR" 4 .IX Item "-pk7out" Takes an input message and writes out a \s-1PEM\s0 encoded PKCS#7 structure. .IP "\fB\-resign\fR" 4 .IX Item "-resign" Resign a message: take an existing message and one or more new signers. .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" The input message to be encrypted or signed or the \s-1MIME\s0 message to be decrypted or verified. .IP "\fB\-inform SMIME|PEM|DER\fR" 4 .IX Item "-inform SMIME|PEM|DER" This specifies the input format for the PKCS#7 structure. The default is \fB\s-1SMIME\s0\fR which reads an S/MIME format message. \fB\s-1PEM\s0\fR and \fB\s-1DER\s0\fR format change this to expect \s-1PEM\s0 and \s-1DER\s0 format PKCS#7 structures instead. This currently only affects the input format of the PKCS#7 structure, if no PKCS#7 structure is being input (for example with \&\fB\-encrypt\fR or \fB\-sign\fR) this option has no effect. .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" The message text that has been decrypted or verified or the output \s-1MIME\s0 format message that has been signed or verified. .IP "\fB\-outform SMIME|PEM|DER\fR" 4 .IX Item "-outform SMIME|PEM|DER" This specifies the output format for the PKCS#7 structure. The default is \fB\s-1SMIME\s0\fR which write an S/MIME format message. \fB\s-1PEM\s0\fR and \fB\s-1DER\s0\fR format change this to write \s-1PEM\s0 and \s-1DER\s0 format PKCS#7 structures instead. This currently only affects the output format of the PKCS#7 structure, if no PKCS#7 structure is being output (for example with \&\fB\-verify\fR or \fB\-decrypt\fR) this option has no effect. .IP "\fB\-stream \-indef \-noindef\fR" 4 .IX Item "-stream -indef -noindef" The \fB\-stream\fR and \fB\-indef\fR options are equivalent and enable streaming I/O for encoding operations. This permits single pass processing of data without the need to hold the entire contents in memory, potentially supporting very large files. Streaming is automatically set for S/MIME signing with detached data if the output format is \fB\s-1SMIME\s0\fR it is currently off by default for all other operations. .IP "\fB\-noindef\fR" 4 .IX Item "-noindef" Disable streaming I/O where it would produce and indefinite length constructed encoding. This option currently has no effect. In future streaming will be enabled by default on all relevant operations and this option will disable it. .IP "\fB\-content filename\fR" 4 .IX Item "-content filename" This specifies a file containing the detached content, this is only useful with the \fB\-verify\fR command. This is only usable if the PKCS#7 structure is using the detached signature form where the content is not included. This option will override any content if the input format is S/MIME and it uses the multipart/signed \s-1MIME\s0 content type. .IP "\fB\-text\fR" 4 .IX Item "-text" This option adds plain text (text/plain) \s-1MIME\s0 headers to the supplied message if encrypting or signing. If decrypting or verifying it strips off text headers: if the decrypted or verified message is not of \s-1MIME\s0 type text/plain then an error occurs. .IP "\fB\-CAfile file\fR" 4 .IX Item "-CAfile file" A file containing trusted \s-1CA\s0 certificates, only used with \fB\-verify\fR. .IP "\fB\-CApath dir\fR" 4 .IX Item "-CApath dir" A directory containing trusted \s-1CA\s0 certificates, only used with \&\fB\-verify\fR. This directory must be a standard certificate directory: that is a hash of each subject name (using \fBx509 \-hash\fR) should be linked to each certificate. .IP "\fB\-no\-CAfile\fR" 4 .IX Item "-no-CAfile" Do not load the trusted \s-1CA\s0 certificates from the default file location. .IP "\fB\-no\-CApath\fR" 4 .IX Item "-no-CApath" Do not load the trusted \s-1CA\s0 certificates from the default directory location. .IP "\fB\-md digest\fR" 4 .IX Item "-md digest" Digest algorithm to use when signing or resigning. If not present then the default digest algorithm for the signing key will be used (usually \s-1SHA1\s0). .IP "\fB\-\f(BIcipher\fB\fR" 4 .IX Item "-cipher" The encryption algorithm to use. For example \s-1DES\s0 (56 bits) \- \fB\-des\fR, triple \s-1DES\s0 (168 bits) \- \fB\-des3\fR, \&\fBEVP_get_cipherbyname()\fR function) can also be used preceded by a dash, for example \fB\-aes\-128\-cbc\fR. See \fBenc\fR for list of ciphers supported by your version of OpenSSL. .Sp If not specified triple \s-1DES\s0 is used. Only used with \fB\-encrypt\fR. .IP "\fB\-nointern\fR" 4 .IX Item "-nointern" When verifying a message normally certificates (if any) included in the message are searched for the signing certificate. With this option only the certificates specified in the \fB\-certfile\fR option are used. The supplied certificates can still be used as untrusted CAs however. .IP "\fB\-noverify\fR" 4 .IX Item "-noverify" Do not verify the signers certificate of a signed message. .IP "\fB\-nochain\fR" 4 .IX Item "-nochain" Do not do chain verification of signers certificates: that is don't use the certificates in the signed message as untrusted CAs. .IP "\fB\-nosigs\fR" 4 .IX Item "-nosigs" Don't try to verify the signatures on the message. .IP "\fB\-nocerts\fR" 4 .IX Item "-nocerts" When signing a message the signer's certificate is normally included with this option it is excluded. This will reduce the size of the signed message but the verifier must have a copy of the signers certificate available locally (passed using the \fB\-certfile\fR option for example). .IP "\fB\-noattr\fR" 4 .IX Item "-noattr" Normally when a message is signed a set of attributes are included which include the signing time and supported symmetric algorithms. With this option they are not included. .IP "\fB\-binary\fR" 4 .IX Item "-binary" Normally the input message is converted to \*(L"canonical\*(R" format which is effectively using \s-1CR\s0 and \s-1LF\s0 as end of line: as required by the S/MIME specification. When this option is present no translation occurs. This is useful when handling binary data which may not be in \s-1MIME\s0 format. .IP "\fB\-crlfeol\fR" 4 .IX Item "-crlfeol" Normally the output file uses a single \fB\s-1LF\s0\fR as end of line. When this option is present \fB\s-1CRLF\s0\fR is used instead. .IP "\fB\-nodetach\fR" 4 .IX Item "-nodetach" When signing a message use opaque signing: this form is more resistant to translation by mail relays but it cannot be read by mail agents that do not support S/MIME. Without this option cleartext signing with the \s-1MIME\s0 type multipart/signed is used. .IP "\fB\-certfile file\fR" 4 .IX Item "-certfile file" Allows additional certificates to be specified. When signing these will be included with the message. When verifying these will be searched for the signers certificates. The certificates should be in \s-1PEM\s0 format. .IP "\fB\-signer file\fR" 4 .IX Item "-signer file" A signing certificate when signing or resigning a message, this option can be used multiple times if more than one signer is required. If a message is being verified then the signers certificates will be written to this file if the verification was successful. .IP "\fB\-recip file\fR" 4 .IX Item "-recip file" The recipients certificate when decrypting a message. This certificate must match one of the recipients of the message or an error occurs. .IP "\fB\-inkey file_or_id\fR" 4 .IX Item "-inkey file_or_id" The private key to use when signing or decrypting. This must match the corresponding certificate. If this option is not specified then the private key must be included in the certificate file specified with the \fB\-recip\fR or \fB\-signer\fR file. When signing this option can be used multiple times to specify successive keys. If no engine is used, the argument is taken as a file; if an engine is specified, the argument is given to the engine as a key identifier. .IP "\fB\-passin arg\fR" 4 .IX Item "-passin arg" The private key password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fBcert.pem...\fR" 4 .IX Item "cert.pem..." One or more certificates of message recipients: used when encrypting a message. .IP "\fB\-to, \-from, \-subject\fR" 4 .IX Item "-to, -from, -subject" The relevant mail headers. These are included outside the signed portion of a message so they may be included manually. If signing then many S/MIME mail clients check the signers certificate's email address matches that specified in the From: address. .IP "\fB\-attime\fR, \fB\-check_ss_sig\fR, \fB\-crl_check\fR, \fB\-crl_check_all\fR, \fB\-explicit_policy\fR, \fB\-extended_crl\fR, \fB\-ignore_critical\fR, \fB\-inhibit_any\fR, \fB\-inhibit_map\fR, \fB\-no_alt_chains\fR, \fB\-partial_chain\fR, \fB\-policy\fR, \fB\-policy_check\fR, \fB\-policy_print\fR, \fB\-purpose\fR, \fB\-suiteB_128\fR, \fB\-suiteB_128_only\fR, \fB\-suiteB_192\fR, \fB\-trusted_first\fR, \fB\-use_deltas\fR, \fB\-auth_level\fR, \fB\-verify_depth\fR, \fB\-verify_email\fR, \fB\-verify_hostname\fR, \fB\-verify_ip\fR, \fB\-verify_name\fR, \fB\-x509_strict\fR" 4 .IX Item "-attime, -check_ss_sig, -crl_check, -crl_check_all, -explicit_policy, -extended_crl, -ignore_critical, -inhibit_any, -inhibit_map, -no_alt_chains, -partial_chain, -policy, -policy_check, -policy_print, -purpose, -suiteB_128, -suiteB_128_only, -suiteB_192, -trusted_first, -use_deltas, -auth_level, -verify_depth, -verify_email, -verify_hostname, -verify_ip, -verify_name, -x509_strict" Set various options of certificate chain verification. See \&\fBverify\fR\|(1) manual page for details. .SH "NOTES" .IX Header "NOTES" The \s-1MIME\s0 message must be sent without any blank lines between the headers and the output. Some mail programs will automatically add a blank line. Piping the mail directly to sendmail is one way to achieve the correct format. .PP The supplied message to be signed or encrypted must include the necessary \s-1MIME\s0 headers or many S/MIME clients won't display it properly (if at all). You can use the \fB\-text\fR option to automatically add plain text headers. .PP A \*(L"signed and encrypted\*(R" message is one where a signed message is then encrypted. This can be produced by encrypting an already signed message: see the examples section. .PP This version of the program only allows one signer per message but it will verify multiple signers on received messages. Some S/MIME clients choke if a message contains multiple signers. It is possible to sign messages \*(L"in parallel\*(R" by signing an already signed message. .PP The options \fB\-encrypt\fR and \fB\-decrypt\fR reflect common usage in S/MIME clients. Strictly speaking these process PKCS#7 enveloped data: PKCS#7 encrypted data is used for other purposes. .PP The \fB\-resign\fR option uses an existing message digest when adding a new signer. This means that attributes must be present in at least one existing signer using the same message digest or this operation will fail. .PP The \fB\-stream\fR and \fB\-indef\fR options enable streaming I/O support. As a result the encoding is \s-1BER\s0 using indefinite length constructed encoding and no longer \s-1DER.\s0 Streaming is supported for the \fB\-encrypt\fR operation and the \&\fB\-sign\fR operation if the content is not detached. .PP Streaming is always used for the \fB\-sign\fR operation with detached data but since the content is no longer part of the PKCS#7 structure the encoding remains \s-1DER.\s0 .SH "EXIT CODES" .IX Header "EXIT CODES" .IP "0" 4 The operation was completely successfully. .IP "1" 4 .IX Item "1" An error occurred parsing the command options. .IP "2" 4 .IX Item "2" One of the input files could not be read. .IP "3" 4 .IX Item "3" An error occurred creating the PKCS#7 file or when reading the \s-1MIME\s0 message. .IP "4" 4 .IX Item "4" An error occurred decrypting or verifying the message. .IP "5" 4 .IX Item "5" The message was verified correctly but an error occurred writing out the signers certificates. .SH "EXAMPLES" .IX Header "EXAMPLES" Create a cleartext signed message: .PP .Vb 2 \& openssl smime \-sign \-in message.txt \-text \-out mail.msg \e \& \-signer mycert.pem .Ve .PP Create an opaque signed message: .PP .Vb 2 \& openssl smime \-sign \-in message.txt \-text \-out mail.msg \-nodetach \e \& \-signer mycert.pem .Ve .PP Create a signed message, include some additional certificates and read the private key from another file: .PP .Vb 2 \& openssl smime \-sign \-in in.txt \-text \-out mail.msg \e \& \-signer mycert.pem \-inkey mykey.pem \-certfile mycerts.pem .Ve .PP Create a signed message with two signers: .PP .Vb 2 \& openssl smime \-sign \-in message.txt \-text \-out mail.msg \e \& \-signer mycert.pem \-signer othercert.pem .Ve .PP Send a signed message under Unix directly to sendmail, including headers: .PP .Vb 3 \& openssl smime \-sign \-in in.txt \-text \-signer mycert.pem \e \& \-from steve@openssl.org \-to someone@somewhere \e \& \-subject "Signed message" | sendmail someone@somewhere .Ve .PP Verify a message and extract the signer's certificate if successful: .PP .Vb 1 \& openssl smime \-verify \-in mail.msg \-signer user.pem \-out signedtext.txt .Ve .PP Send encrypted mail using triple \s-1DES:\s0 .PP .Vb 3 \& openssl smime \-encrypt \-in in.txt \-from steve@openssl.org \e \& \-to someone@somewhere \-subject "Encrypted message" \e \& \-des3 user.pem \-out mail.msg .Ve .PP Sign and encrypt mail: .PP .Vb 4 \& openssl smime \-sign \-in ml.txt \-signer my.pem \-text \e \& | openssl smime \-encrypt \-out mail.msg \e \& \-from steve@openssl.org \-to someone@somewhere \e \& \-subject "Signed and Encrypted message" \-des3 user.pem .Ve .PP Note: the encryption command does not include the \fB\-text\fR option because the message being encrypted already has \s-1MIME\s0 headers. .PP Decrypt mail: .PP .Vb 1 \& openssl smime \-decrypt \-in mail.msg \-recip mycert.pem \-inkey key.pem .Ve .PP The output from Netscape form signing is a PKCS#7 structure with the detached signature format. You can use this program to verify the signature by line wrapping the base64 encoded structure and surrounding it with: .PP .Vb 2 \& \-\-\-\-\-BEGIN PKCS7\-\-\-\-\- \& \-\-\-\-\-END PKCS7\-\-\-\-\- .Ve .PP and using the command: .PP .Vb 1 \& openssl smime \-verify \-inform PEM \-in signature.pem \-content content.txt .Ve .PP Alternatively you can base64 decode the signature and use: .PP .Vb 1 \& openssl smime \-verify \-inform DER \-in signature.der \-content content.txt .Ve .PP Create an encrypted message using 128 bit Camellia: .PP .Vb 1 \& openssl smime \-encrypt \-in plain.txt \-camellia128 \-out mail.msg cert.pem .Ve .PP Add a signer to an existing message: .PP .Vb 1 \& openssl smime \-resign \-in mail.msg \-signer newsign.pem \-out mail2.msg .Ve .SH "BUGS" .IX Header "BUGS" The \s-1MIME\s0 parser isn't very clever: it seems to handle most messages that I've thrown at it but it may choke on others. .PP The code currently will only write out the signer's certificate to a file: if the signer has a separate encryption certificate this must be manually extracted. There should be some heuristic that determines the correct encryption certificate. .PP Ideally a database should be maintained of a certificates for each email address. .PP The code doesn't currently take note of the permitted symmetric encryption algorithms as supplied in the SMIMECapabilities signed attribute. This means the user has to manually include the correct encryption algorithm. It should store the list of permitted ciphers in a database and only use those. .PP No revocation checking is done on the signer's certificate. .PP The current code can only handle S/MIME v2 messages, the more complex S/MIME v3 structures may cause parsing errors. .SH "HISTORY" .IX Header "HISTORY" The use of multiple \fB\-signer\fR options and the \fB\-resign\fR command were first added in OpenSSL 1.0.0 .PP The \-no_alt_chains option was added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2021 The OpenSSL Project Authors.

Since this is a diagnostic tool that needs some knowledge of the \s-1SSL\s0 protocol to use properly, most users will not need to use it. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-help\fR" 4 .IX Item "-help" Print out a usage message. .IP "\fB\-inform DER|PEM\fR" 4 .IX Item "-inform DER|PEM" This specifies the input format. The \fB\s-1DER\s0\fR option uses an \s-1ASN1 DER\s0 encoded format containing session details. The precise format can vary from one version to the next. The \fB\s-1PEM\s0\fR form is the default format: it consists of the \fB\s-1DER\s0\fR format base64 encoded with additional header and footer lines. .IP "\fB\-outform DER|PEM|NSS\fR" 4 .IX Item "-outform DER|PEM|NSS" This specifies the output format. The \fB\s-1PEM\s0\fR and \fB\s-1DER\s0\fR options have the same meaning and default as the \fB\-inform\fR option. The \fB\s-1NSS\s0\fR option outputs the session id and the master key in \s-1NSS\s0 keylog format. .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" This specifies the input filename to read session information from or standard input by default. .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" This specifies the output filename to write session information to or standard output if this option is not specified. .IP "\fB\-text\fR" 4 .IX Item "-text" Prints out the various public or private key components in plain text in addition to the encoded version. .IP "\fB\-cert\fR" 4 .IX Item "-cert" If a certificate is present in the session it will be output using this option, if the \fB\-text\fR option is also present then it will be printed out in text form. .IP "\fB\-noout\fR" 4 .IX Item "-noout" This option prevents output of the encoded version of the session. .IP "\fB\-context \s-1ID\s0\fR" 4 .IX Item "-context ID" This option can set the session id so the output session information uses the supplied \s-1ID.\s0 The \s-1ID\s0 can be any string of characters.

If \fB\-servername\fR is not provided, the \s-1TLS SNI\s0 extension will be populated with the name given to \fB\-connect\fR if it follows a \s-1DNS\s0 name format. If \fB\-connect\fR is not provided either, the \s-1SNI\s0 is set to \*(L"localhost\*(R". This is the default since OpenSSL 1.1.1. .Sp Even though \s-1SNI\s0 should normally be a \s-1DNS\s0 name and not an \s-1IP\s0 address, if \&\fB\-servername\fR is provided then that name will be sent, regardless of whether it is a \s-1DNS\s0 name or not. .Sp This option cannot be used in conjunction with \fB\-noservername\fR. .IP "\fB\-noservername\fR" 4 .IX Item "-noservername" Suppresses sending of the \s-1SNI\s0 (Server Name Indication) extension in the ClientHello message. Cannot be used in conjunction with the \fB\-servername\fR or <\-dane_tlsa_domain> options. .IP "\fB\-cert certname\fR" 4 .IX Item "-cert certname" The certificate to use, if one is requested by the server. The default is not to use a certificate. .IP "\fB\-certform format\fR" 4 .IX Item "-certform format" The certificate format to use: \s-1DER\s0 or \s-1PEM. PEM\s0 is the default. .IP "\fB\-key keyfile\fR" 4 .IX Item "-key keyfile" The private key to use.

These behave in the same manner as the \fB\-cert\fR, \fB\-key\fR and \fB\-cert_chain\fR options. When specified, the callback returning the first valid chain will be in use by the client. .IP "\fB\-xchain_build\fR" 4 .IX Item "-xchain_build" Specify whether the application should build the certificate chain to be provided to the server for the extra certificates provided via \fB\-xkey infile\fR, \&\fB\-xcert infile\fR, \fB\-xchain\fR options. .IP "\fB\-xcertform PEM|DER\fR, \fB\-xkeyform PEM|DER\fR" 4 .IX Item "-xcertform PEM|DER, -xkeyform PEM|DER" Extra certificate and private key format respectively. .IP "\fB\-pass arg\fR" 4 .IX Item "-pass arg" the private key password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-verify depth\fR" 4 .IX Item "-verify depth" The verify depth to use. This specifies the maximum length of the server certificate chain and turns on server certificate verification. Currently the verify operation continues after errors so all the problems with a certificate chain can be seen. As a side effect the connection will never fail due to a server certificate verify failure. .IP "\fB\-verify_return_error\fR" 4 .IX Item "-verify_return_error" Return verification errors instead of continuing. This will typically abort the handshake with a fatal error. .IP "\fB\-nameopt option\fR" 4 .IX Item "-nameopt option" Option which determines how the subject or issuer names are displayed. The \&\fBoption\fR argument can be a single option or multiple options separated by commas. Alternatively the \fB\-nameopt\fR switch may be used more than once to set multiple options. See the \fBx509\fR\|(1) manual page for details. .IP "\fB\-CApath directory\fR" 4 .IX Item "-CApath directory" The directory to use for server certificate verification.

Only supported for \s-1TLS 1.3\s0 .IP "\fB\-dane_tlsa_domain domain\fR" 4 .IX Item "-dane_tlsa_domain domain" Enable \s-1RFC6698/RFC7671 DANE TLSA\s0 authentication and specify the \&\s-1TLSA\s0 base domain which becomes the default \s-1SNI\s0 hint and the primary reference identifier for hostname checks. This must be used in combination with at least one instance of the \fB\-dane_tlsa_rrdata\fR option below. .Sp When \s-1DANE\s0 authentication succeeds, the diagnostic output will include the lowest (closest to 0) depth at which a \s-1TLSA\s0 record authenticated a chain certificate. When that \s-1TLSA\s0 record is a \*(L"2 1 0\*(R" trust anchor public key that signed (rather than matched) the top-most certificate of the chain, the result is reported as \*(L"\s-1TA\s0 public key verified\*(R". Otherwise, either the \s-1TLSA\s0 record \*(L"matched \s-1TA\s0 certificate\*(R" at a positive depth or else \*(L"matched \s-1EE\s0 certificate\*(R" at depth 0. .IP "\fB\-dane_tlsa_rrdata rrdata\fR" 4 .IX Item "-dane_tlsa_rrdata rrdata" Use one or more times to specify the \s-1RRDATA\s0 fields of the \s-1DANE TLSA\s0 RRset associated with the target service. The \fBrrdata\fR value is specified in \*(L"presentation form\*(R", that is four whitespace separated fields that specify the usage, selector, matching type and associated data, with the last of these encoded in hexadecimal. Optional whitespace is ignored in the associated data field.

For some applications, primarily web browsers, it is not safe to disable name checks due to \*(L"unknown key share\*(R" attacks, in which a malicious server can convince a client that a connection to a victim server is instead a secure connection to the malicious server. The malicious server may then be able to violate cross-origin scripting restrictions. Thus, despite the text of \s-1RFC7671,\s0 name checks are by default enabled for \&\s-1\fBDANE\-EE\s0\fR\|(3) \s-1TLSA\s0 records, and can be disabled in applications where it is safe to do so. In particular, \s-1SMTP\s0 and \s-1XMPP\s0 clients should set this option as \s-1SRV\s0 and \s-1MX\s0 records already make it possible for a remote domain to redirect client connections to any server of its choice, and in any case \s-1SMTP\s0 and \s-1XMPP\s0 clients do not execute scripts downloaded from remote servers. .IP "\fB\-attime\fR, \fB\-check_ss_sig\fR, \fB\-crl_check\fR, \fB\-crl_check_all\fR, \fB\-explicit_policy\fR, \fB\-extended_crl\fR, \fB\-ignore_critical\fR, \fB\-inhibit_any\fR, \fB\-inhibit_map\fR, \fB\-no_alt_chains\fR, \fB\-no_check_time\fR, \fB\-partial_chain\fR, \fB\-policy\fR, \fB\-policy_check\fR, \fB\-policy_print\fR, \fB\-purpose\fR, \fB\-suiteB_128\fR, \fB\-suiteB_128_only\fR, \fB\-suiteB_192\fR, \fB\-trusted_first\fR, \fB\-use_deltas\fR, \fB\-auth_level\fR, \fB\-verify_depth\fR, \fB\-verify_email\fR, \fB\-verify_hostname\fR, \fB\-verify_ip\fR, \fB\-verify_name\fR, \fB\-x509_strict\fR" 4 .IX Item "-attime, -check_ss_sig, -crl_check, -crl_check_all, -explicit_policy, -extended_crl, -ignore_critical, -inhibit_any, -inhibit_map, -no_alt_chains, -no_check_time, -partial_chain, -policy, -policy_check, -policy_print, -purpose, -suiteB_128, -suiteB_128_only, -suiteB_192, -trusted_first, -use_deltas, -auth_level, -verify_depth, -verify_email, -verify_hostname, -verify_ip, -verify_name, -x509_strict" Set various certificate chain validation options.

It is \&\fBnot\fR a verified chain. .IP "\fB\-prexit\fR" 4 .IX Item "-prexit" Print session information when the program exits. This will always attempt to print out information even if the connection fails. Normally information will only be printed out once if the connection succeeds. This option is useful because the cipher in use may be renegotiated or the connection may fail because a client certificate is required or is requested only after an attempt is made to access a certain \s-1URL.\s0 Note: the output produced by this option is not always accurate because a connection might never have been established. .IP "\fB\-state\fR" 4 .IX Item "-state" Prints out the \s-1SSL\s0 session states. .IP "\fB\-debug\fR" 4 .IX Item "-debug" Print extensive debugging information including a hex dump of all traffic. .IP "\fB\-msg\fR" 4 .IX Item "-msg" Show all protocol messages with hex dump. .IP "\fB\-trace\fR" 4 .IX Item "-trace" Show verbose trace output of protocol messages.

This implicitly turns on \fB\-ign_eof\fR as well. .IP "\fB\-no_ign_eof\fR" 4 .IX Item "-no_ign_eof" Shut down the connection when end of file is reached in the input. Can be used to override the implicit \fB\-ign_eof\fR after \fB\-quiet\fR. .IP "\fB\-psk_identity identity\fR" 4 .IX Item "-psk_identity identity" Use the \s-1PSK\s0 identity \fBidentity\fR when using a \s-1PSK\s0 cipher suite. The default value is \*(L"Client_identity\*(R" (without the quotes). .IP "\fB\-psk key\fR" 4 .IX Item "-psk key" Use the \s-1PSK\s0 key \fBkey\fR when using a \s-1PSK\s0 cipher suite. The key is given as a hexadecimal number without leading 0x, for example \-psk 1a2b3c4d. This option must be provided in order to use a \s-1PSK\s0 cipher. .IP "\fB\-psk_session file\fR" 4 .IX Item "-psk_session file" Use the pem encoded \s-1SSL_SESSION\s0 data stored in \fBfile\fR as the basis of a \s-1PSK.\s0 Note that this will only work if TLSv1.3 is negotiated. .IP "\fB\-ssl3\fR, \fB\-tls1\fR, \fB\-tls1_1\fR, \fB\-tls1_2\fR, \fB\-tls1_3\fR, \fB\-no_ssl3\fR, \fB\-no_tls1\fR, \fB\-no_tls1_1\fR, \fB\-no_tls1_2\fR, \fB\-no_tls1_3\fR" 4 .IX Item "-ssl3, -tls1, -tls1_1, -tls1_2, -tls1_3, -no_ssl3, -no_tls1, -no_tls1_1, -no_tls1_2, -no_tls1_3" These options require or disable the use of the specified \s-1SSL\s0 or \s-1TLS\s0 protocols. By default \fBs_client\fR will negotiate the highest mutually supported protocol version. When a specific \s-1TLS\s0 version is required, only that version will be offered to and accepted from the server. Note that not all protocols and flags may be available, depending on how OpenSSL was built. .IP "\fB\-dtls\fR, \fB\-dtls1\fR, \fB\-dtls1_2\fR" 4 .IX Item "-dtls, -dtls1, -dtls1_2" These options make \fBs_client\fR use \s-1DTLS\s0 protocols instead of \s-1TLS.\s0 With \fB\-dtls\fR, \fBs_client\fR will negotiate any supported \s-1DTLS\s0 protocol version, whilst \fB\-dtls1\fR and \fB\-dtls1_2\fR will only support \s-1DTLS1.0\s0 and \s-1DTLS1.2\s0 respectively. .IP "\fB\-sctp\fR" 4 .IX Item "-sctp" Use \s-1SCTP\s0 for the transport protocol instead of \s-1UDP\s0 in \s-1DTLS.\s0 Must be used in conjunction with \fB\-dtls\fR, \fB\-dtls1\fR or \fB\-dtls1_2\fR. This option is only available where OpenSSL has support for \s-1SCTP\s0 enabled. .IP "\fB\-sctp_label_bug\fR" 4 .IX Item "-sctp_label_bug" Use the incorrect behaviour of older OpenSSL implementations when computing endpoint-pair shared secrets for \s-1DTLS/SCTP.\s0 This allows communication with older broken implementations but breaks interoperability with correct implementations. Must be used in conjunction with \fB\-sctp\fR. This option is only available where OpenSSL has support for \s-1SCTP\s0 enabled. .IP "\fB\-fallback_scsv\fR" 4 .IX Item "-fallback_scsv" Send \s-1TLS_FALLBACK_SCSV\s0 in the ClientHello. .IP "\fB\-async\fR" 4 .IX Item "-async" Switch on asynchronous mode. Cryptographic operations will be performed asynchronously. This will only have an effect if an asynchronous capable engine is also used via the \fB\-engine\fR option. For test purposes the dummy async engine (dasync) can be used (if available). .IP "\fB\-max_send_frag int\fR" 4 .IX Item "-max_send_frag int" The maximum size of data fragment to send. See \fBSSL_CTX_set_max_send_fragment\fR\|(3) for further information. .IP "\fB\-split_send_frag int\fR" 4 .IX Item "-split_send_frag int" The size used to split data for encrypt pipelines. If more data is written in one go than this value then it will be split into multiple pipelines, up to the maximum number of pipelines defined by max_pipelines. This only has an effect if a suitable cipher suite has been negotiated, an engine that supports pipelining has been loaded, and max_pipelines is greater than 1. See \&\fBSSL_CTX_set_split_send_fragment\fR\|(3) for further information. .IP "\fB\-max_pipelines int\fR" 4 .IX Item "-max_pipelines int" The maximum number of encrypt/decrypt pipelines to be used. This will only have an effect if an engine has been loaded that supports pipelining (e.g. the dasync engine) and a suitable cipher suite has been negotiated. The default value is 1. See \fBSSL_CTX_set_max_pipelines\fR\|(3) for further information. .IP "\fB\-read_buf int\fR" 4 .IX Item "-read_buf int" The default read buffer size to be used for connections. This will only have an effect if the buffer size is larger than the size that would otherwise be used and pipelining is in use (see \fBSSL_CTX_set_default_read_buffer_len\fR\|(3) for further information). .IP "\fB\-bugs\fR" 4 .IX Item "-bugs" There are several known bugs in \s-1SSL\s0 and \s-1TLS\s0 implementations. Adding this option enables various workarounds. .IP "\fB\-comp\fR" 4 .IX Item "-comp" Enables support for \s-1SSL/TLS\s0 compression. This option was introduced in OpenSSL 1.1.0. \&\s-1TLS\s0 compression is not recommended and is off by default as of OpenSSL 1.1.0. .IP "\fB\-no_comp\fR" 4 .IX Item "-no_comp" Disables support for \s-1SSL/TLS\s0 compression. \&\s-1TLS\s0 compression is not recommended and is off by default as of OpenSSL 1.1.0. .IP "\fB\-brief\fR" 4 .IX Item "-brief" Only provide a brief summary of connection parameters instead of the normal verbose output. .IP "\fB\-sigalgs sigalglist\fR" 4 .IX Item "-sigalgs sigalglist" Specifies the list of signature algorithms that are sent by the client.

For a list of all curves, use: .Sp .Vb 1 \& $ openssl ecparam \-list_curves .Ve .IP "\fB\-cipher cipherlist\fR" 4 .IX Item "-cipher cipherlist" This allows the TLSv1.2 and below cipher list sent by the client to be modified. This list will be combined with any TLSv1.3 ciphersuites that have been configured. Although the server determines which ciphersuite is used it should take the first supported cipher in the list sent by the client. See the \&\fBciphers\fR command for more information. .IP "\fB\-ciphersuites val\fR" 4 .IX Item "-ciphersuites val" This allows the TLSv1.3 ciphersuites sent by the client to be modified. This list will be combined with any TLSv1.2 and below ciphersuites that have been configured. Although the server determines which cipher suite is used it should take the first supported cipher in the list sent by the client. See the \&\fBciphers\fR command for more information. The format for this list is a simple colon (\*(L":\*(R") separated list of TLSv1.3 ciphersuite names. .IP "\fB\-starttls protocol\fR" 4 .IX Item "-starttls protocol" Send the protocol-specific message(s) to switch to \s-1TLS\s0 for communication. \&\fBprotocol\fR is a keyword for the intended protocol. Currently, the only supported keywords are \*(L"smtp\*(R", \*(L"pop3\*(R", \*(L"imap\*(R", \*(L"ftp\*(R", \*(L"xmpp\*(R", \*(L"xmpp-server\*(R", \&\*(L"irc\*(R", \*(L"postgres\*(R", \*(L"mysql\*(R", \*(L"lmtp\*(R", \*(L"nntp\*(R", \*(L"sieve\*(R" and \*(L"ldap\*(R". .IP "\fB\-xmpphost hostname\fR" 4 .IX Item "-xmpphost hostname" This option, when used with \*(L"\-starttls xmpp\*(R" or \*(L"\-starttls xmpp-server\*(R", specifies the host for the \*(L"to\*(R" attribute of the stream element. If this option is not specified, then the host specified with \*(L"\-connect\*(R" will be used. .Sp This option is an alias of the \fB\-name\fR option for \*(L"xmpp\*(R" and \*(L"xmpp-server\*(R". .IP "\fB\-name hostname\fR" 4 .IX Item "-name hostname" This option is used to specify hostname information for various protocols used with \fB\-starttls\fR option. Currently only \*(L"xmpp\*(R", \*(L"xmpp-server\*(R", \&\*(L"smtp\*(R" and \*(L"lmtp\*(R" can utilize this \fB\-name\fR option. .Sp If this option is used with \*(L"\-starttls xmpp\*(R" or \*(L"\-starttls xmpp-server\*(R", if specifies the host for the \*(L"to\*(R" attribute of the stream element. If this option is not specified, then the host specified with \*(L"\-connect\*(R" will be used. .Sp If this option is used with \*(L"\-starttls lmtp\*(R" or \*(L"\-starttls smtp\*(R", it specifies the name to use in the \*(L"\s-1LMTP LHLO\*(R"\s0 or \*(L"\s-1SMTP EHLO\*(R"\s0 message, respectively. If this option is not specified, then \*(L"mail.example.com\*(R" will be used. .IP "\fB\-tlsextdebug\fR" 4 .IX Item "-tlsextdebug" Print out a hex dump of any \s-1TLS\s0 extensions received from the server. .IP "\fB\-no_ticket\fR" 4 .IX Item "-no_ticket" Disable RFC4507bis session ticket support. .IP "\fB\-sess_out filename\fR" 4 .IX Item "-sess_out filename" Output \s-1SSL\s0 session to \fBfilename\fR. .IP "\fB\-sess_in sess.pem\fR" 4 .IX Item "-sess_in sess.pem" Load \s-1SSL\s0 session from \fBfilename\fR. The client will attempt to resume a connection from this session. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBs_client\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fB\-serverinfo types\fR" 4 .IX Item "-serverinfo types" A list of comma-separated \s-1TLS\s0 Extension Types (numbers between 0 and 65535). Each type will be sent as an empty ClientHello \s-1TLS\s0 Extension. The server's response (if any) will be encoded and displayed as a \s-1PEM\s0 file. .IP "\fB\-status\fR" 4 .IX Item "-status" Sends a certificate status request to the server (\s-1OCSP\s0 stapling). The server response (if any) is printed out. .IP "\fB\-alpn protocols\fR, \fB\-nextprotoneg protocols\fR" 4 .IX Item "-alpn protocols, -nextprotoneg protocols" These flags enable the Enable the Application-Layer Protocol Negotiation or Next Protocol Negotiation (\s-1NPN\s0) extension, respectively. \s-1ALPN\s0 is the \&\s-1IETF\s0 standard and replaces \s-1NPN.\s0 The \fBprotocols\fR list is a comma-separated list of protocol names that the client should advertise support for. The list should contain the most desirable protocols first. Protocol names are printable \s-1ASCII\s0 strings, for example \*(L"http/1.1\*(R" or \*(L"spdy/3\*(R". An empty list of protocols is treated specially and will cause the client to advertise support for the \s-1TLS\s0 extension but disconnect just after receiving ServerHello with a list of server supported protocols. The flag \fB\-nextprotoneg\fR cannot be specified if \fB\-tls1_3\fR is used. .IP "\fB\-ct\fR, \fB\-noct\fR" 4 .IX Item "-ct, -noct" Use one of these two options to control whether Certificate Transparency (\s-1CT\s0) is enabled (\fB\-ct\fR) or disabled (\fB\-noct\fR). If \s-1CT\s0 is enabled, signed certificate timestamps (SCTs) will be requested from the server and reported at handshake completion. .Sp Enabling \s-1CT\s0 also enables \s-1OCSP\s0 stapling, as this is one possible delivery method for SCTs. .IP "\fB\-ctlogfile\fR" 4 .IX Item "-ctlogfile" A file containing a list of known Certificate Transparency logs. See \&\fBSSL_CTX_set_ctlog_list_file\fR\|(3) for the expected file format. .IP "\fB\-keylogfile file\fR" 4 .IX Item "-keylogfile file" Appends \s-1TLS\s0 secrets to the specified keylog file such that external programs (like Wireshark) can decrypt \s-1TLS\s0 connections. .IP "\fB\-early_data file\fR" 4 .IX Item "-early_data file" Reads the contents of the specified file and attempts to send it as early data to the server. This will only work with resumed sessions that support early data and when the server accepts the early data. .IP "\fB\-enable_pha\fR" 4 .IX Item "-enable_pha" For TLSv1.3 only, send the Post-Handshake Authentication extension. This will happen whether or not a certificate has been provided via \fB\-cert\fR. .IP "\fB[target]\fR" 4 .IX Item "[target]" Rather than providing \fB\-connect\fR, the target hostname and optional port may be provided as a single positional argument after all options. If neither this nor \fB\-connect\fR are provided, falls back to attempting to connect to localhost on port 4433. .SH "CONNECTED COMMANDS" .IX Header "CONNECTED COMMANDS" If a connection is established with an \s-1SSL\s0 server then any data received from the server is displayed and any key presses will be sent to the server. If end of file is reached then the connection will be closed down. When used interactively (which means neither \fB\-quiet\fR nor \fB\-ign_eof\fR have been given), then certain commands are also recognized which perform special operations. These commands are a letter which must appear at the start of a line. They are listed below. .IP "\fBQ\fR" 4 .IX Item "Q" End the current \s-1SSL\s0 connection and exit. .IP "\fBR\fR" 4 .IX Item "R" Renegotiate the \s-1SSL\s0 session (TLSv1.2 and below only). .IP "\fBB\fR" 4 .IX Item "B" Send a heartbeat message to the server (\s-1DTLS\s0 only) .IP "\fBk\fR" 4 .IX Item "k" Send a key update message to the server (TLSv1.3 only) .IP "\fBK\fR" 4 .IX Item "K" Send a key update message to the server and request one back (TLSv1.3 only) .SH "NOTES" .IX Header "NOTES" \&\fBs_client\fR can be used to debug \s-1SSL\s0 servers. To connect to an \s-1SSL HTTP\s0 server the command: .PP .Vb 1 \& openssl s_client \-connect servername:443 .Ve .PP would typically be used (https uses port 443). If the connection succeeds then an \s-1HTTP\s0 command can be given such as \*(L"\s-1GET /\*(R"\s0 to retrieve a web page. .PP If the handshake fails then there are several possible causes, if it is nothing obvious like no client certificate then the \fB\-bugs\fR, \&\fB\-ssl3\fR, \fB\-tls1\fR, \fB\-no_ssl3\fR, \fB\-no_tls1\fR options can be tried in case it is a buggy server. In particular you should play with these options \fBbefore\fR submitting a bug report to an OpenSSL mailing list. .PP A frequent problem when attempting to get client certificates working is that a web client complains it has no certificates or gives an empty list to choose from. This is normally because the server is not sending the clients certificate authority in its \*(L"acceptable \s-1CA\s0 list\*(R" when it requests a certificate. By using \fBs_client\fR the \s-1CA\s0 list can be viewed and checked. However, some servers only request client authentication after a specific \s-1URL\s0 is requested. To obtain the list in this case it is necessary to use the \fB\-prexit\fR option and send an \s-1HTTP\s0 request for an appropriate page. .PP If a certificate is specified on the command line using the \fB\-cert\fR option it will not be used unless the server specifically requests a client certificate. Therefore, merely including a client certificate on the command line is no guarantee that the certificate works. .PP If there are problems verifying a server certificate then the \&\fB\-showcerts\fR option can be used to show all the certificates sent by the server. .PP The \fBs_client\fR utility is a test tool and is designed to continue the handshake after any certificate verification errors. As a result it will accept any certificate chain (trusted or not) sent by the peer. Non-test applications should \fBnot\fR do this as it makes them vulnerable to a \s-1MITM\s0 attack. This behaviour can be changed by with the \fB\-verify_return_error\fR option: any verify errors are then returned aborting the handshake. .PP The \fB\-bind\fR option may be useful if the server or a firewall requires connections to come from some particular address and or port. .SH "BUGS" .IX Header "BUGS" Because this program has a lot of options and also because some of the techniques used are rather old, the C source of \fBs_client\fR is rather hard to read and not a model of how things should be done. A typical \s-1SSL\s0 client program would be much simpler. .PP The \fB\-prexit\fR option is a bit of a hack. We should really report information whenever a session is renegotiated. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CONF_cmd\fR\|(3), \fBsess_id\fR\|(1), \fBs_server\fR\|(1), \fBciphers\fR\|(1), \&\fBSSL_CTX_set_max_send_fragment\fR\|(3), \fBSSL_CTX_set_split_send_fragment\fR\|(3), \&\fBSSL_CTX_set_max_pipelines\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The \fB\-no_alt_chains\fR option was added in OpenSSL 1.1.0.

The \fB\s-1DER\s0\fR option uses an \s-1ASN.1 DER\s0 encoded form compatible with \s-1RFC 3279\s0 EcpkParameters. The \s-1PEM\s0 form is the default format: it consists of the \fB\s-1DER\s0\fR format base64 encoded with additional header and footer lines. .IP "\fB\-outform DER|PEM\fR" 4 .IX Item "-outform DER|PEM" This specifies the output format, the options have the same meaning and default as the \fB\-inform\fR option. .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" This specifies the input filename to read parameters from or standard input if this option is not specified. .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" This specifies the output filename parameters to. Standard output is used if this option is not present. The output filename should \fBnot\fR be the same as the input filename. .IP "\fB\-noout\fR" 4 .IX Item "-noout" This option inhibits the output of the encoded version of the parameters. .IP "\fB\-text\fR" 4 .IX Item "-text" This option prints out the \s-1EC\s0 parameters in human readable form. .IP "\fB\-C\fR" 4 .IX Item "-C" This option converts the \s-1EC\s0 parameters into C code. The parameters can then be loaded by calling the \fBget_ec_group_XXX()\fR function. .IP "\fB\-check\fR" 4 .IX Item "-check" Validate the elliptic curve parameters. .IP "\fB\-name arg\fR" 4 .IX Item "-name arg" Use the \s-1EC\s0 parameters with the specified 'short' name. Use \fB\-list_curves\fR to get a list of all currently implemented \s-1EC\s0 parameters. .IP "\fB\-list_curves\fR" 4 .IX Item "-list_curves" If this options is specified \fBecparam\fR will print out a list of all currently implemented \s-1EC\s0 parameters names and exit. .IP "\fB\-conv_form\fR" 4 .IX Item "-conv_form" This specifies how the points on the elliptic curve are converted into octet strings. Possible values are: \fBcompressed\fR, \fBuncompressed\fR (the default value) and \fBhybrid\fR. For more information regarding the point conversion forms please read the X9.62 standard. \&\fBNote\fR Due to patent issues the \fBcompressed\fR option is disabled by default for binary curves and can be enabled by defining the preprocessor macro \fB\s-1OPENSSL_EC_BIN_PT_COMP\s0\fR at compile time. .IP "\fB\-param_enc arg\fR" 4 .IX Item "-param_enc arg" This specifies how the elliptic curve parameters are encoded.

The default value is \fBnamed_curve\fR. \&\fBNote\fR the \fBimplicitlyCA\fR alternative, as specified in \s-1RFC 3279,\s0 is currently not implemented in OpenSSL. .IP "\fB\-no_seed\fR" 4 .IX Item "-no_seed" This option inhibits that the 'seed' for the parameter generation is included in the ECParameters structure (see \s-1RFC 3279\s0). .IP "\fB\-genkey\fR" 4 .IX Item "-genkey" This option will generate an \s-1EC\s0 private key using the specified parameters. .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBecparam\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed.

This is prohibited and will result in an error if it is a non-conforming \s-1CA\s0 certificate with key usage restrictions not including the keyCertSign bit. This verification is disabled by default because it doesn't add any security. .IP "\fB\-CRLfile file\fR" 4 .IX Item "-CRLfile file" The \fBfile\fR should contain one or more CRLs in \s-1PEM\s0 format. This option can be specified more than once to include CRLs from multiple \&\fBfiles\fR. .IP "\fB\-crl_download\fR" 4 .IX Item "-crl_download" Attempt to download \s-1CRL\s0 information for this certificate. .IP "\fB\-crl_check\fR" 4 .IX Item "-crl_check" Checks end entity certificate validity by attempting to look up a valid \s-1CRL.\s0 If a valid \s-1CRL\s0 cannot be found an error occurs. .IP "\fB\-crl_check_all\fR" 4 .IX Item "-crl_check_all" Checks the validity of \fBall\fR certificates in the chain by attempting to look up valid CRLs. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine \fBid\fR will cause \fBverify\fR\|(1) to attempt to load the specified engine. The engine will then be set as the default for all its supported algorithms. If you want to load certificates or CRLs that require engine support via any of the \fB\-trusted\fR, \fB\-untrusted\fR or \fB\-CRLfile\fR options, the \fB\-engine\fR option must be specified before those options. .IP "\fB\-explicit_policy\fR" 4 .IX Item "-explicit_policy" Set policy variable require-explicit-policy (see \s-1RFC5280\s0). .IP "\fB\-extended_crl\fR" 4 .IX Item "-extended_crl" Enable extended \s-1CRL\s0 features such as indirect CRLs and alternate \s-1CRL\s0 signing keys. .IP "\fB\-ignore_critical\fR" 4 .IX Item "-ignore_critical" Normally if an unhandled critical extension is present which is not supported by OpenSSL the certificate is rejected (as required by \s-1RFC5280\s0). If this option is set critical extensions are ignored. .IP "\fB\-inhibit_any\fR" 4 .IX Item "-inhibit_any" Set policy variable inhibit-any-policy (see \s-1RFC5280\s0). .IP "\fB\-inhibit_map\fR" 4 .IX Item "-inhibit_map" Set policy variable inhibit-policy-mapping (see \s-1RFC5280\s0). .IP "\fB\-nameopt option\fR" 4 .IX Item "-nameopt option" Option which determines how the subject or issuer names are displayed. The \&\fBoption\fR argument can be a single option or multiple options separated by commas. Alternatively the \fB\-nameopt\fR switch may be used more than once to set multiple options. See the \fBx509\fR\|(1) manual page for details. .IP "\fB\-no_check_time\fR" 4 .IX Item "-no_check_time" This option suppresses checking the validity period of certificates and CRLs against the current time. If option \fB\-attime timestamp\fR is used to specify a verification time, the check is not suppressed. .IP "\fB\-partial_chain\fR" 4 .IX Item "-partial_chain" Allow verification to succeed even if a \fIcomplete\fR chain cannot be built to a self-signed trust-anchor, provided it is possible to construct a chain to a trusted certificate that might not be self-signed. .IP "\fB\-policy arg\fR" 4 .IX Item "-policy arg" Enable policy processing and add \fBarg\fR to the user-initial-policy-set (see \&\s-1RFC5280\s0). The policy \fBarg\fR can be an object name an \s-1OID\s0 in numeric form. This argument can appear more than once. .IP "\fB\-policy_check\fR" 4 .IX Item "-policy_check" Enables certificate policy processing. .IP "\fB\-policy_print\fR" 4 .IX Item "-policy_print" Print out diagnostics related to policy processing. .IP "\fB\-purpose purpose\fR" 4 .IX Item "-purpose purpose" The intended use for the certificate. If this option is not specified, \&\fBverify\fR will not consider certificate purpose during chain verification. Currently accepted uses are \fBsslclient\fR, \fBsslserver\fR, \fBnssslserver\fR, \&\fBsmimesign\fR, \fBsmimeencrypt\fR. See the \fB\s-1VERIFY OPERATION\s0\fR section for more information. .IP "\fB\-suiteB_128_only\fR, \fB\-suiteB_128\fR, \fB\-suiteB_192\fR" 4 .IX Item "-suiteB_128_only, -suiteB_128, -suiteB_192" Enable the Suite B mode operation at 128 bit Level of Security, 128 bit or 192 bit, or only 192 bit Level of Security respectively. See \s-1RFC6460\s0 for details. In particular the supported signature algorithms are reduced to support only \s-1ECDSA\s0 and \s-1SHA256\s0 or \s-1SHA384\s0 and only the elliptic curves P\-256 and P\-384. .IP "\fB\-trusted_first\fR" 4 .IX Item "-trusted_first" When constructing the certificate chain, use the trusted certificates specified via \fB\-CAfile\fR, \fB\-CApath\fR or \fB\-trusted\fR before any certificates specified via \&\fB\-untrusted\fR. This can be useful in environments with Bridge or Cross-Certified CAs. As of OpenSSL 1.1.0 this option is on by default and cannot be disabled. .IP "\fB\-no_alt_chains\fR" 4 .IX Item "-no_alt_chains" By default, unless \fB\-trusted_first\fR is specified, when building a certificate chain, if the first certificate chain found is not trusted, then OpenSSL will attempt to replace untrusted issuer certificates with certificates from the trust store to see if an alternative chain can be found that is trusted. As of OpenSSL 1.1.0, with \fB\-trusted_first\fR always on, this option has no effect. .IP "\fB\-untrusted file\fR" 4 .IX Item "-untrusted file" A \fBfile\fR of additional untrusted certificates (intermediate issuer CAs) used to construct a certificate chain from the subject certificate to a trust-anchor. The \fBfile\fR should contain one or more certificates in \s-1PEM\s0 format. This option can be specified more than once to include untrusted certificates from multiple \fBfiles\fR. .IP "\fB\-trusted file\fR" 4 .IX Item "-trusted file" A \fBfile\fR of trusted certificates, which must be self-signed, unless the \&\fB\-partial_chain\fR option is specified. The \fBfile\fR contains one or more certificates in \s-1PEM\s0 format. With this option, no additional (e.g., default) certificate lists are consulted. That is, the only trust-anchors are those listed in \fBfile\fR. This option can be specified more than once to include trusted certificates from multiple \fBfiles\fR. This option implies the \fB\-no\-CAfile\fR and \fB\-no\-CApath\fR options. This option cannot be used in combination with either of the \fB\-CAfile\fR or \&\fB\-CApath\fR options. .IP "\fB\-use_deltas\fR" 4 .IX Item "-use_deltas" Enable support for delta CRLs. .IP "\fB\-verbose\fR" 4 .IX Item "-verbose" Print extra information about the operations being performed. .IP "\fB\-auth_level level\fR" 4 .IX Item "-auth_level level" Set the certificate chain authentication security level to \fBlevel\fR. The authentication security level determines the acceptable signature and public key strength when verifying certificate chains. For a certificate chain to validate, the public keys of all the certificates must meet the specified security \fBlevel\fR. The signature algorithm security level is enforced for all the certificates in the chain except for the chain's \fItrust anchor\fR, which is either directly trusted or validated by means other than its signature. See \fBSSL_CTX_set_security_level\fR\|(3) for the definitions of the available levels. The default security level is \-1, or \*(L"not set\*(R". At security level 0 or lower all algorithms are acceptable. Security level 1 requires at least 80\-bit\-equivalent security and is broadly interoperable, though it will, for example, reject \s-1MD5\s0 signatures or \s-1RSA\s0 keys shorter than 1024 bits. .IP "\fB\-verify_depth num\fR" 4 .IX Item "-verify_depth num" Limit the certificate chain to \fBnum\fR intermediate \s-1CA\s0 certificates. A maximal depth chain can have up to \fBnum+2\fR certificates, since neither the end-entity certificate nor the trust-anchor certificate count against the \&\fB\-verify_depth\fR limit. .IP "\fB\-verify_email email\fR" 4 .IX Item "-verify_email email" Verify if the \fBemail\fR matches the email address in Subject Alternative Name or the email in the subject Distinguished Name. .IP "\fB\-verify_hostname hostname\fR" 4 .IX Item "-verify_hostname hostname" Verify if the \fBhostname\fR matches \s-1DNS\s0 name in Subject Alternative Name or Common Name in the subject certificate. .IP "\fB\-verify_ip ip\fR" 4 .IX Item "-verify_ip ip" Verify if the \fBip\fR matches the \s-1IP\s0 address in Subject Alternative Name of the subject certificate. .IP "\fB\-verify_name name\fR" 4 .IX Item "-verify_name name" Use default verification policies like trust model and required certificate policies identified by \fBname\fR. The trust model determines which auxiliary trust or reject OIDs are applicable to verifying the given certificate chain. See the \fB\-addtrust\fR and \fB\-addreject\fR options of the \fBx509\fR\|(1) command-line utility. Supported policy names include: \fBdefault\fR, \fBpkcs7\fR, \fBsmime_sign\fR, \&\fBssl_client\fR, \fBssl_server\fR. These mimics the combinations of purpose and trust settings used in \s-1SSL, CMS\s0 and S/MIME. As of OpenSSL 1.1.0, the trust model is inferred from the purpose when not specified, so the \fB\-verify_name\fR options are functionally equivalent to the corresponding \fB\-purpose\fR settings. .IP "\fB\-x509_strict\fR" 4 .IX Item "-x509_strict" For strict X.509 compliance, disable non-compliant workarounds for broken certificates. .IP "\fB\-show_chain\fR" 4 .IX Item "-show_chain" Display information about the certificate chain that has been built (if successful). Certificates in the chain that came from the untrusted list will be flagged as \*(L"untrusted\*(R". .IP "\fB\-\fR" 4 .IX Item "-" Indicates the last option. All arguments following this are assumed to be certificate files. This is useful if the first certificate filename begins with a \fB\-\fR. .IP "\fBcertificates\fR" 4 .IX Item "certificates" One or more certificates to verify. If no certificates are given, \fBverify\fR will attempt to read a certificate from standard input. Certificates must be in \s-1PEM\s0 format. .SH "VERIFY OPERATION" .IX Header "VERIFY OPERATION" The \fBverify\fR program uses the same functions as the internal \s-1SSL\s0 and S/MIME verification, therefore, this description applies to these verify operations too. .PP There is one crucial difference between the verify operations performed by the \fBverify\fR program: wherever possible an attempt is made to continue after an error whereas normally the verify operation would halt on the first error. This allows all the problems with a certificate chain to be determined. .PP The verify operation consists of a number of separate steps. .PP Firstly a certificate chain is built up starting from the supplied certificate and ending in the root \s-1CA.\s0 It is an error if the whole chain cannot be built up. The chain is built up by looking up the issuers certificate of the current certificate. If a certificate is found which is its own issuer it is assumed to be the root \&\s-1CA.\s0 .PP The process of 'looking up the issuers certificate' itself involves a number of steps. After all certificates whose subject name matches the issuer name of the current certificate are subject to further tests. The relevant authority key identifier components of the current certificate (if present) must match the subject key identifier (if present) and issuer and serial number of the candidate issuer, in addition the keyUsage extension of the candidate issuer (if present) must permit certificate signing. .PP The lookup first looks in the list of untrusted certificates and if no match is found the remaining lookups are from the trusted certificates. The root \s-1CA\s0 is always looked up in the trusted certificate list: if the certificate to verify is a root certificate then an exact match must be found in the trusted list. .PP The second operation is to check every untrusted certificate's extensions for consistency with the supplied purpose. If the \fB\-purpose\fR option is not included then no checks are done. The supplied or \*(L"leaf\*(R" certificate must have extensions compatible with the supplied purpose and all other certificates must also be valid \&\s-1CA\s0 certificates. The precise extensions required are described in more detail in the \fB\s-1CERTIFICATE EXTENSIONS\s0\fR section of the \fBx509\fR utility. .PP The third operation is to check the trust settings on the root \s-1CA.\s0 The root \s-1CA\s0 should be trusted for the supplied purpose. For compatibility with previous versions of OpenSSL, a certificate with no trust settings is considered to be valid for all purposes. .PP The final operation is to check the validity of the certificate chain. For each element in the chain, including the root \s-1CA\s0 certificate, the validity period as specified by the \f(CW\*(C`notBefore\*(C'\fR and \f(CW\*(C`notAfter\*(C'\fR fields is checked against the current system time. The \fB\-attime\fR flag may be used to use a reference time other than \*(L"now.\*(R" The certificate signature is checked as well (except for the signature of the typically self-signed root \s-1CA\s0 certificate, which is verified only if the \fB\-check_ss_sig\fR option is given). .PP If all operations complete successfully then certificate is considered valid. If any operation fails then the certificate is not valid. .SH "DIAGNOSTICS" .IX Header "DIAGNOSTICS" When a verify operation fails the output messages can be somewhat cryptic. The general form of the error message is: .PP .Vb 2 \& server.pem: /C=AU/ST=Queensland/O=CryptSoft Pty Ltd/CN=Test CA (1024 bit) \& error 24 at 1 depth lookup:invalid CA certificate .Ve .PP The first line contains the name of the certificate being verified followed by the subject name of the certificate. The second line contains the error number and the depth. The depth is number of the certificate being verified when a problem was detected starting with zero for the certificate being verified itself then 1 for the \s-1CA\s0 that signed the certificate and so on. Finally a text version of the error number is presented. .PP A partial list of the error codes and messages is shown below, this also includes the name of the error code as defined in the header file x509_vfy.h Some of the error codes are defined but never returned: these are described as \*(L"unused\*(R". .IP "\fBX509_V_OK\fR" 4 .IX Item "X509_V_OK" The operation was successful. .IP "\fBX509_V_ERR_UNSPECIFIED\fR" 4 .IX Item "X509_V_ERR_UNSPECIFIED" Unspecified error; should not happen. .IP "\fBX509_V_ERR_UNABLE_TO_GET_ISSUER_CERT\fR" 4 .IX Item "X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT" The issuer certificate of a looked up certificate could not be found. This normally means the list of trusted certificates is not complete. .IP "\fBX509_V_ERR_UNABLE_TO_GET_CRL\fR" 4 .IX Item "X509_V_ERR_UNABLE_TO_GET_CRL" The \s-1CRL\s0 of a certificate could not be found. .IP "\fBX509_V_ERR_UNABLE_TO_DECRYPT_CERT_SIGNATURE\fR" 4 .IX Item "X509_V_ERR_UNABLE_TO_DECRYPT_CERT_SIGNATURE" The certificate signature could not be decrypted. This means that the actual signature value could not be determined rather than it not matching the expected value, this is only meaningful for \s-1RSA\s0 keys. .IP "\fBX509_V_ERR_UNABLE_TO_DECRYPT_CRL_SIGNATURE\fR" 4 .IX Item "X509_V_ERR_UNABLE_TO_DECRYPT_CRL_SIGNATURE" The \s-1CRL\s0 signature could not be decrypted: this means that the actual signature value could not be determined rather than it not matching the expected value.

A \&\s-1TSA\s0 can be part of a \s-1PKI\s0 deployment and its role is to provide long term proof of the existence of a certain datum before a particular time. Here is a brief description of the protocol: .IP "1." 4 The \s-1TSA\s0 client computes a one-way hash value for a data file and sends the hash to the \s-1TSA.\s0 .IP "2." 4 The \s-1TSA\s0 attaches the current date and time to the received hash value, signs them and sends the timestamp token back to the client. By creating this token the \s-1TSA\s0 certifies the existence of the original data file at the time of response generation. .IP "3." 4 The \s-1TSA\s0 client receives the timestamp token and verifies the signature on it. It also checks if the token contains the same hash value that it had sent to the \s-1TSA.\s0 .PP There is one \s-1DER\s0 encoded protocol data unit defined for transporting a timestamp request to the \s-1TSA\s0 and one for sending the timestamp response back to the client. The \fBts\fR command has three main functions: creating a timestamp request based on a data file, creating a timestamp response based on a request, verifying if a response corresponds to a particular request or a data file. .PP There is no support for sending the requests/responses automatically over \s-1HTTP\s0 or \s-1TCP\s0 yet as suggested in \s-1RFC 3161.\s0 The users must send the requests either by ftp or e\-mail. .SH "OPTIONS" .IX Header "OPTIONS" .SS "Time Stamp Request generation" .IX Subsection "Time Stamp Request generation" The \fB\-query\fR switch can be used for creating and printing a timestamp request with the following options: .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fB\-config\fR configfile" 4 .IX Item "-config configfile" The configuration file to use. Optional; for a description of the default value, see \*(L"\s-1COMMAND SUMMARY\*(R"\s0 in \fBopenssl\fR\|(1). .IP "\fB\-data\fR file_to_hash" 4 .IX Item "-data file_to_hash" The data file for which the timestamp request needs to be created. stdin is the default if neither the \fB\-data\fR nor the \fB\-digest\fR parameter is specified. (Optional) .IP "\fB\-digest\fR digest_bytes" 4 .IX Item "-digest digest_bytes" It is possible to specify the message imprint explicitly without the data file. The imprint must be specified in a hexadecimal format, two characters per byte, the bytes optionally separated by colons (e.g. 1A:F6:01:... or 1AF601...). The number of bytes must match the message digest algorithm in use. (Optional) .IP "\fB\-\f(BIdigest\fB\fR" 4 .IX Item "-digest" The message digest to apply to the data file. Any digest supported by the OpenSSL \fBdgst\fR command can be used. The default is \s-1SHA\-1.\s0 (Optional) .IP "\fB\-tspolicy\fR object_id" 4 .IX Item "-tspolicy object_id" The policy that the client expects the \s-1TSA\s0 to use for creating the timestamp token. Either the dotted \s-1OID\s0 notation or \s-1OID\s0 names defined in the config file can be used. If no policy is requested the \s-1TSA\s0 will use its own default policy. (Optional) .IP "\fB\-no_nonce\fR" 4 .IX Item "-no_nonce" No nonce is specified in the request if this option is given. Otherwise a 64 bit long pseudo-random none is included in the request. It is recommended to use nonce to protect against replay-attacks. (Optional) .IP "\fB\-cert\fR" 4 .IX Item "-cert" The \s-1TSA\s0 is expected to include its signing certificate in the response. (Optional) .IP "\fB\-in\fR request.tsq" 4 .IX Item "-in request.tsq" This option specifies a previously created timestamp request in \s-1DER\s0 format that will be printed into the output file. Useful when you need to examine the content of a request in human-readable format. (Optional) .IP "\fB\-out\fR request.tsq" 4 .IX Item "-out request.tsq" Name of the output file to which the request will be written. Default is stdout. (Optional) .IP "\fB\-text\fR" 4 .IX Item "-text" If this option is specified the output is human-readable text format instead of \s-1DER.\s0 (Optional) .SS "Time Stamp Response generation" .IX Subsection "Time Stamp Response generation" A timestamp response (TimeStampResp) consists of a response status and the timestamp token itself (ContentInfo), if the token generation was successful. The \fB\-reply\fR command is for creating a timestamp response or timestamp token based on a request and printing the response/token in human-readable format. If \fB\-token_out\fR is not specified the output is always a timestamp response (TimeStampResp), otherwise it is a timestamp token (ContentInfo). .IP "\fB\-config\fR configfile" 4 .IX Item "-config configfile" The configuration file to use. Optional; for a description of the default value, see \*(L"\s-1COMMAND SUMMARY\*(R"\s0 in \fBopenssl\fR\|(1). See \fB\s-1CONFIGURATION FILE OPTIONS\s0\fR for configurable variables. .IP "\fB\-section\fR tsa_section" 4 .IX Item "-section tsa_section" The name of the config file section containing the settings for the response generation. If not specified the default \s-1TSA\s0 section is used, see \fB\s-1CONFIGURATION FILE OPTIONS\s0\fR for details. (Optional) .IP "\fB\-queryfile\fR request.tsq" 4 .IX Item "-queryfile request.tsq" The name of the file containing a \s-1DER\s0 encoded timestamp request. (Optional) .IP "\fB\-passin\fR password_src" 4 .IX Item "-passin password_src" Specifies the password source for the private key of the \s-1TSA.\s0 See \&\*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). (Optional) .IP "\fB\-signer\fR tsa_cert.pem" 4 .IX Item "-signer tsa_cert.pem" The signer certificate of the \s-1TSA\s0 in \s-1PEM\s0 format. The \s-1TSA\s0 signing certificate must have exactly one extended key usage assigned to it: timeStamping. The extended key usage must also be critical, otherwise the certificate is going to be refused. Overrides the \fBsigner_cert\fR variable of the config file. (Optional) .IP "\fB\-inkey\fR file_or_id" 4 .IX Item "-inkey file_or_id" The signer private key of the \s-1TSA\s0 in \s-1PEM\s0 format. Overrides the \&\fBsigner_key\fR config file option. (Optional) If no engine is used, the argument is taken as a file; if an engine is specified, the argument is given to the engine as a key identifier. .IP "\fB\-\f(BIdigest\fB\fR" 4 .IX Item "-digest" Signing digest to use. Overrides the \fBsigner_digest\fR config file option. (Mandatory unless specified in the config file) .IP "\fB\-chain\fR certs_file.pem" 4 .IX Item "-chain certs_file.pem" The collection of certificates in \s-1PEM\s0 format that will all be included in the response in addition to the signer certificate if the \fB\-cert\fR option was used for the request. This file is supposed to contain the certificate chain for the signer certificate from its issuer upwards. The \fB\-reply\fR command does not build a certificate chain automatically.

They are functionally equivalent, except for minor differences noted below. .PP \&\fBrehash\fR scans directories and calculates a hash value of each \&\f(CW\*(C`.pem\*(C'\fR, \f(CW\*(C`.crt\*(C'\fR, \f(CW\*(C`.cer\*(C'\fR, or \f(CW\*(C`.crl\*(C'\fR file in the specified directory list and creates symbolic links for each file, where the name of the link is the hash value. (If the platform does not support symbolic links, a copy is made.) This utility is useful as many programs that use OpenSSL require directories to be set up like this in order to find certificates. .PP If any directories are named on the command line, then those are processed in turn. If not, then the \fB\s-1SSL_CERT_DIR\s0\fR environment variable is consulted; this should be a colon-separated list of directories, like the Unix \fB\s-1PATH\s0\fR variable. If that is not set then the default directory (installation-specific but often \fB/usr/local/ssl/certs\fR) is processed. .PP In order for a directory to be processed, the user must have write permissions on that directory, otherwise an error will be generated. .PP The links created are of the form \f(CW\*(C`HHHHHHHH.D\*(C'\fR, where each \fBH\fR is a hexadecimal character and \fBD\fR is a single decimal digit. When processing a directory, \fBrehash\fR will first remove all links that have a name in that syntax, even if they are being used for some other purpose. To skip the removal step, use the \fB\-n\fR flag. Hashes for \s-1CRL\s0's look similar except the letter \fBr\fR appears after the period, like this: \f(CW\*(C`HHHHHHHH.rD\*(C'\fR. .PP Multiple objects may have the same hash; they will be indicated by incrementing the \fBD\fR value. Duplicates are found by comparing the full \s-1SHA\-1\s0 fingerprint. A warning will be displayed if a duplicate is found. .PP A warning will also be displayed if there are files that cannot be parsed as either a certificate or a \s-1CRL\s0 or if more than one such object appears in the file. .SS "Script Configuration" .IX Subsection "Script Configuration" The \fBc_rehash\fR script uses the \fBopenssl\fR program to compute the hashes and fingerprints. If not found in the user's \fB\s-1PATH\s0\fR, then set the \&\fB\s-1OPENSSL\s0\fR environment variable to the full pathname. Any program can be used, it will be invoked as follows for either a certificate or \s-1CRL:\s0 .PP .Vb 2 \& $OPENSSL x509 \-hash \-fingerprint \-noout \-in FILENAME \& $OPENSSL crl \-hash \-fingerprint \-noout \-in FILENAME .Ve .PP where \fB\s-1FILENAME\s0\fR is the filename.

A pass phrase is prompted for. If none of these options is specified the key is written in plain text. This means that using the \fBdsa\fR utility to read in an encrypted key with no encryption option can be used to remove the pass phrase from a key, or by setting the encryption options it can be use to add or change the pass phrase.

Streaming is automatically set for S/MIME signing with detached data if the output format is \fB\s-1SMIME\s0\fR it is currently off by default for all other operations. .IP "\fB\-noindef\fR" 4 .IX Item "-noindef" Disable streaming I/O where it would produce and indefinite length constructed encoding. This option currently has no effect. In future streaming will be enabled by default on all relevant operations and this option will disable it. .IP "\fB\-content filename\fR" 4 .IX Item "-content filename" This specifies a file containing the detached content, this is only useful with the \fB\-verify\fR command. This is only usable if the \s-1CMS\s0 structure is using the detached signature form where the content is not included. This option will override any content if the input format is S/MIME and it uses the multipart/signed \s-1MIME\s0 content type. .IP "\fB\-text\fR" 4 .IX Item "-text" This option adds plain text (text/plain) \s-1MIME\s0 headers to the supplied message if encrypting or signing. If decrypting or verifying it strips off text headers: if the decrypted or verified message is not of \s-1MIME\s0 type text/plain then an error occurs. .IP "\fB\-noout\fR" 4 .IX Item "-noout" For the \fB\-cmsout\fR operation do not output the parsed \s-1CMS\s0 structure. This is useful when combined with the \fB\-print\fR option or if the syntax of the \s-1CMS\s0 structure is being checked. .IP "\fB\-print\fR" 4 .IX Item "-print" For the \fB\-cmsout\fR operation print out all fields of the \s-1CMS\s0 structure. This is mainly useful for testing purposes. .IP "\fB\-CAfile file\fR" 4 .IX Item "-CAfile file" A file containing trusted \s-1CA\s0 certificates, only used with \fB\-verify\fR. .IP "\fB\-CApath dir\fR" 4 .IX Item "-CApath dir" A directory containing trusted \s-1CA\s0 certificates, only used with \&\fB\-verify\fR. This directory must be a standard certificate directory: that is a hash of each subject name (using \fBx509 \-hash\fR) should be linked to each certificate. .IP "\fB\-no\-CAfile\fR" 4 .IX Item "-no-CAfile" Do not load the trusted \s-1CA\s0 certificates from the default file location .IP "\fB\-no\-CApath\fR" 4 .IX Item "-no-CApath" Do not load the trusted \s-1CA\s0 certificates from the default directory location .IP "\fB\-md digest\fR" 4 .IX Item "-md digest" Digest algorithm to use when signing or resigning. If not present then the default digest algorithm for the signing key will be used (usually \s-1SHA1\s0). .IP "\fB\-\f(BIcipher\fB\fR" 4 .IX Item "-cipher" The encryption algorithm to use. For example triple \s-1DES\s0 (168 bits) \- \fB\-des3\fR or 256 bit \s-1AES\s0 \- \fB\-aes256\fR. Any standard algorithm name (as used by the \&\fBEVP_get_cipherbyname()\fR function) can also be used preceded by a dash, for example \fB\-aes\-128\-cbc\fR. See \fBenc\fR\|(1) for a list of ciphers supported by your version of OpenSSL. .Sp If not specified triple \s-1DES\s0 is used. Only used with \fB\-encrypt\fR and \&\fB\-EncryptedData_create\fR commands. .IP "\fB\-nointern\fR" 4 .IX Item "-nointern" When verifying a message normally certificates (if any) included in the message are searched for the signing certificate. With this option only the certificates specified in the \fB\-certfile\fR option are used. The supplied certificates can still be used as untrusted CAs however. .IP "\fB\-noverify\fR" 4 .IX Item "-noverify" Do not verify the signers certificate of a signed message. .IP "\fB\-nocerts\fR" 4 .IX Item "-nocerts" When signing a message the signer's certificate is normally included with this option it is excluded. This will reduce the size of the signed message but the verifier must have a copy of the signers certificate available locally (passed using the \fB\-certfile\fR option for example). .IP "\fB\-noattr\fR" 4 .IX Item "-noattr" Normally when a message is signed a set of attributes are included which include the signing time and supported symmetric algorithms. With this option they are not included. .IP "\fB\-nosmimecap\fR" 4 .IX Item "-nosmimecap" Exclude the list of supported algorithms from signed attributes, other options such as signing time and content type are still included. .IP "\fB\-binary\fR" 4 .IX Item "-binary" Normally the input message is converted to \*(L"canonical\*(R" format which is effectively using \s-1CR\s0 and \s-1LF\s0 as end of line: as required by the S/MIME specification. When this option is present no translation occurs. This is useful when handling binary data which may not be in \s-1MIME\s0 format. .IP "\fB\-crlfeol\fR" 4 .IX Item "-crlfeol" Normally the output file uses a single \fB\s-1LF\s0\fR as end of line. When this option is present \fB\s-1CRLF\s0\fR is used instead. .IP "\fB\-asciicrlf\fR" 4 .IX Item "-asciicrlf" When signing use \s-1ASCII CRLF\s0 format canonicalisation. This strips trailing whitespace from all lines, deletes trailing blank lines at \s-1EOF\s0 and sets the encapsulated content type. This option is normally used with detached content and an output signature format of \s-1DER.\s0 This option is not normally needed when verifying as it is enabled automatically if the encapsulated content format is detected. .IP "\fB\-nodetach\fR" 4 .IX Item "-nodetach" When signing a message use opaque signing: this form is more resistant to translation by mail relays but it cannot be read by mail agents that do not support S/MIME. Without this option cleartext signing with the \s-1MIME\s0 type multipart/signed is used. .IP "\fB\-certfile file\fR" 4 .IX Item "-certfile file" Allows additional certificates to be specified. When signing these will be included with the message. When verifying these will be searched for the signers certificates. The certificates should be in \s-1PEM\s0 format. .IP "\fB\-certsout file\fR" 4 .IX Item "-certsout file" Any certificates contained in the message are written to \fBfile\fR. .IP "\fB\-signer file\fR" 4 .IX Item "-signer file" A signing certificate when signing or resigning a message, this option can be used multiple times if more than one signer is required. If a message is being verified then the signers certificates will be written to this file if the verification was successful. .IP "\fB\-recip file\fR" 4 .IX Item "-recip file" When decrypting a message this specifies the recipients certificate. The certificate must match one of the recipients of the message or an error occurs. .Sp When encrypting a message this option may be used multiple times to specify each recipient. This form \fBmust\fR be used if customised parameters are required (for example to specify RSA-OAEP). .Sp Only certificates carrying \s-1RSA,\s0 Diffie-Hellman or \s-1EC\s0 keys are supported by this option. .IP "\fB\-keyid\fR" 4 .IX Item "-keyid" Use subject key identifier to identify certificates instead of issuer name and serial number. The supplied certificate \fBmust\fR include a subject key identifier extension. Supported by \fB\-sign\fR and \fB\-encrypt\fR options. .IP "\fB\-receipt_request_all\fR, \fB\-receipt_request_first\fR" 4 .IX Item "-receipt_request_all, -receipt_request_first" For \fB\-sign\fR option include a signed receipt request. Indicate requests should be provided by all recipient or first tier recipients (those mailed directly and not from a mailing list). Ignored it \fB\-receipt_request_from\fR is included. .IP "\fB\-receipt_request_from emailaddress\fR" 4 .IX Item "-receipt_request_from emailaddress" For \fB\-sign\fR option include a signed receipt request. Add an explicit email address where receipts should be supplied. .IP "\fB\-receipt_request_to emailaddress\fR" 4 .IX Item "-receipt_request_to emailaddress" Add an explicit email address where signed receipts should be sent to. This option \fBmust\fR but supplied if a signed receipt it requested. .IP "\fB\-receipt_request_print\fR" 4 .IX Item "-receipt_request_print" For the \fB\-verify\fR operation print out the contents of any signed receipt requests. .IP "\fB\-secretkey key\fR" 4 .IX Item "-secretkey key" Specify symmetric key to use. The key must be supplied in hex format and be consistent with the algorithm used. Supported by the \fB\-EncryptedData_encrypt\fR \&\fB\-EncryptedData_decrypt\fR, \fB\-encrypt\fR and \fB\-decrypt\fR options. When used with \fB\-encrypt\fR or \fB\-decrypt\fR the supplied key is used to wrap or unwrap the content encryption key using an \s-1AES\s0 key in the \fBKEKRecipientInfo\fR type. .IP "\fB\-secretkeyid id\fR" 4 .IX Item "-secretkeyid id" The key identifier for the supplied symmetric key for \fBKEKRecipientInfo\fR type. This option \fBmust\fR be present if the \fB\-secretkey\fR option is used with \&\fB\-encrypt\fR. With \fB\-decrypt\fR operations the \fBid\fR is used to locate the relevant key if it is not supplied then an attempt is used to decrypt any \&\fBKEKRecipientInfo\fR structures. .IP "\fB\-econtent_type type\fR" 4 .IX Item "-econtent_type type" Set the encapsulated content type to \fBtype\fR if not supplied the \fBData\fR type is used. The \fBtype\fR argument can be any valid \s-1OID\s0 name in either text or numerical format. .IP "\fB\-inkey file\fR" 4 .IX Item "-inkey file" The private key to use when signing or decrypting. This must match the corresponding certificate. If this option is not specified then the private key must be included in the certificate file specified with the \fB\-recip\fR or \fB\-signer\fR file. When signing this option can be used multiple times to specify successive keys. .IP "\fB\-keyopt name:opt\fR" 4 .IX Item "-keyopt name:opt" For signing and encryption this option can be used multiple times to set customised parameters for the preceding key or certificate. It can currently be used to set RSA-PSS for signing, RSA-OAEP for encryption or to modify default parameters for \s-1ECDH.\s0 .IP "\fB\-passin arg\fR" 4 .IX Item "-passin arg" The private key password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fBcert.pem...\fR" 4 .IX Item "cert.pem..." One or more certificates of message recipients: used when encrypting a message. .IP "\fB\-to, \-from, \-subject\fR" 4 .IX Item "-to, -from, -subject" The relevant mail headers. These are included outside the signed portion of a message so they may be included manually. If signing then many S/MIME mail clients check the signers certificate's email address matches that specified in the From: address. .IP "\fB\-attime\fR, \fB\-check_ss_sig\fR, \fB\-crl_check\fR, \fB\-crl_check_all\fR, \fB\-explicit_policy\fR, \fB\-extended_crl\fR, \fB\-ignore_critical\fR, \fB\-inhibit_any\fR, \fB\-inhibit_map\fR, \fB\-no_alt_chains\fR, \fB\-no_check_time\fR, \fB\-partial_chain\fR, \fB\-policy\fR, \fB\-policy_check\fR, \fB\-policy_print\fR, \fB\-purpose\fR, \fB\-suiteB_128\fR, \fB\-suiteB_128_only\fR, \fB\-suiteB_192\fR, \fB\-trusted_first\fR, \fB\-use_deltas\fR, \fB\-auth_level\fR, \fB\-verify_depth\fR, \fB\-verify_email\fR, \fB\-verify_hostname\fR, \fB\-verify_ip\fR, \fB\-verify_name\fR, \fB\-x509_strict\fR" 4 .IX Item "-attime, -check_ss_sig, -crl_check, -crl_check_all, -explicit_policy, -extended_crl, -ignore_critical, -inhibit_any, -inhibit_map, -no_alt_chains, -no_check_time, -partial_chain, -policy, -policy_check, -policy_print, -purpose, -suiteB_128, -suiteB_128_only, -suiteB_192, -trusted_first, -use_deltas, -auth_level, -verify_depth, -verify_email, -verify_hostname, -verify_ip, -verify_name, -x509_strict" Set various certificate chain validation options. See the \&\fBverify\fR\|(1) manual page for details. .SH "NOTES" .IX Header "NOTES" The \s-1MIME\s0 message must be sent without any blank lines between the headers and the output. Some mail programs will automatically add a blank line. Piping the mail directly to sendmail is one way to achieve the correct format. .PP The supplied message to be signed or encrypted must include the necessary \s-1MIME\s0 headers or many S/MIME clients won't display it properly (if at all). You can use the \fB\-text\fR option to automatically add plain text headers. .PP A \*(L"signed and encrypted\*(R" message is one where a signed message is then encrypted. This can be produced by encrypting an already signed message: see the examples section. .PP This version of the program only allows one signer per message but it will verify multiple signers on received messages. Some S/MIME clients choke if a message contains multiple signers. It is possible to sign messages \*(L"in parallel\*(R" by signing an already signed message. .PP The options \fB\-encrypt\fR and \fB\-decrypt\fR reflect common usage in S/MIME clients. Strictly speaking these process \s-1CMS\s0 enveloped data: \s-1CMS\s0 encrypted data is used for other purposes. .PP The \fB\-resign\fR option uses an existing message digest when adding a new signer. This means that attributes must be present in at least one existing signer using the same message digest or this operation will fail. .PP The \fB\-stream\fR and \fB\-indef\fR options enable streaming I/O support. As a result the encoding is \s-1BER\s0 using indefinite length constructed encoding and no longer \s-1DER.\s0 Streaming is supported for the \fB\-encrypt\fR operation and the \&\fB\-sign\fR operation if the content is not detached. .PP Streaming is always used for the \fB\-sign\fR operation with detached data but since the content is no longer part of the \s-1CMS\s0 structure the encoding remains \s-1DER.\s0 .PP If the \fB\-decrypt\fR option is used without a recipient certificate then an attempt is made to locate the recipient by trying each potential recipient in turn using the supplied private key. To thwart the \s-1MMA\s0 attack (Bleichenbacher's attack on \s-1PKCS\s0 #1 v1.5 \s-1RSA\s0 padding) all recipients are tried whether they succeed or not and if no recipients match the message is \*(L"decrypted\*(R" using a random key which will typically output garbage. The \fB\-debug_decrypt\fR option can be used to disable the \s-1MMA\s0 attack protection and return an error if no recipient can be found: this option should be used with caution. For a fuller description see \fBCMS_decrypt\fR\|(3)). .SH "EXIT CODES" .IX Header "EXIT CODES" .IP "0" 4 The operation was completely successfully. .IP "1" 4 .IX Item "1" An error occurred parsing the command options. .IP "2" 4 .IX Item "2" One of the input files could not be read. .IP "3" 4 .IX Item "3" An error occurred creating the \s-1CMS\s0 file or when reading the \s-1MIME\s0 message. .IP "4" 4 .IX Item "4" An error occurred decrypting or verifying the message. .IP "5" 4 .IX Item "5" The message was verified correctly but an error occurred writing out the signers certificates. .SH "COMPATIBILITY WITH PKCS#7 format." .IX Header "COMPATIBILITY WITH PKCS#7 format." The \fBsmime\fR utility can only process the older \fBPKCS#7\fR format. The \fBcms\fR utility supports Cryptographic Message Syntax format. Use of some features will result in messages which cannot be processed by applications which only support the older format. These are detailed below. .PP The use of the \fB\-keyid\fR option with \fB\-sign\fR or \fB\-encrypt\fR. .PP The \fB\-outform \s-1PEM\s0\fR option uses different headers. .PP The \fB\-compress\fR option. .PP The \fB\-secretkey\fR option when used with \fB\-encrypt\fR. .PP The use of \s-1PSS\s0 with \fB\-sign\fR. .PP The use of \s-1OAEP\s0 or non-RSA keys with \fB\-encrypt\fR. .PP Additionally the \fB\-EncryptedData_create\fR and \fB\-data_create\fR type cannot be processed by the older \fBsmime\fR command. .SH "EXAMPLES" .IX Header "EXAMPLES" Create a cleartext signed message: .PP .Vb 2 \& openssl cms \-sign \-in message.txt \-text \-out mail.msg \e \& \-signer mycert.pem .Ve .PP Create an opaque signed message .PP .Vb 2 \& openssl cms \-sign \-in message.txt \-text \-out mail.msg \-nodetach \e \& \-signer mycert.pem .Ve .PP Create a signed message, include some additional certificates and read the private key from another file: .PP .Vb 2 \& openssl cms \-sign \-in in.txt \-text \-out mail.msg \e \& \-signer mycert.pem \-inkey mykey.pem \-certfile mycerts.pem .Ve .PP Create a signed message with two signers, use key identifier: .PP .Vb 2 \& openssl cms \-sign \-in message.txt \-text \-out mail.msg \e \& \-signer mycert.pem \-signer othercert.pem \-keyid .Ve .PP Send a signed message under Unix directly to sendmail, including headers: .PP .Vb 3 \& openssl cms \-sign \-in in.txt \-text \-signer mycert.pem \e \& \-from steve@openssl.org \-to someone@somewhere \e \& \-subject "Signed message" | sendmail someone@somewhere .Ve .PP Verify a message and extract the signer's certificate if successful: .PP .Vb 1 \& openssl cms \-verify \-in mail.msg \-signer user.pem \-out signedtext.txt .Ve .PP Send encrypted mail using triple \s-1DES:\s0 .PP .Vb 3 \& openssl cms \-encrypt \-in in.txt \-from steve@openssl.org \e \& \-to someone@somewhere \-subject "Encrypted message" \e \& \-des3 user.pem \-out mail.msg .Ve .PP Sign and encrypt mail: .PP .Vb 4 \& openssl cms \-sign \-in ml.txt \-signer my.pem \-text \e \& | openssl cms \-encrypt \-out mail.msg \e \& \-from steve@openssl.org \-to someone@somewhere \e \& \-subject "Signed and Encrypted message" \-des3 user.pem .Ve .PP Note: the encryption command does not include the \fB\-text\fR option because the message being encrypted already has \s-1MIME\s0 headers. .PP Decrypt mail: .PP .Vb 1 \& openssl cms \-decrypt \-in mail.msg \-recip mycert.pem \-inkey key.pem .Ve .PP The output from Netscape form signing is a PKCS#7 structure with the detached signature format. You can use this program to verify the signature by line wrapping the base64 encoded structure and surrounding it with: .PP .Vb 2 \& \-\-\-\-\-BEGIN PKCS7\-\-\-\-\- \& \-\-\-\-\-END PKCS7\-\-\-\-\- .Ve .PP and using the command, .PP .Vb 1 \& openssl cms \-verify \-inform PEM \-in signature.pem \-content content.txt .Ve .PP alternatively you can base64 decode the signature and use .PP .Vb 1 \& openssl cms \-verify \-inform DER \-in signature.der \-content content.txt .Ve .PP Create an encrypted message using 128 bit Camellia: .PP .Vb 1 \& openssl cms \-encrypt \-in plain.txt \-camellia128 \-out mail.msg cert.pem .Ve .PP Add a signer to an existing message: .PP .Vb 1 \& openssl cms \-resign \-in mail.msg \-signer newsign.pem \-out mail2.msg .Ve .PP Sign mail using RSA-PSS: .PP .Vb 2 \& openssl cms \-sign \-in message.txt \-text \-out mail.msg \e \& \-signer mycert.pem \-keyopt rsa_padding_mode:pss .Ve .PP Create encrypted mail using RSA-OAEP: .PP .Vb 2 \& openssl cms \-encrypt \-in plain.txt \-out mail.msg \e \& \-recip cert.pem \-keyopt rsa_padding_mode:oaep .Ve .PP Use \s-1SHA256 KDF\s0 with an \s-1ECDH\s0 certificate: .PP .Vb 2 \& openssl cms \-encrypt \-in plain.txt \-out mail.msg \e \& \-recip ecdhcert.pem \-keyopt ecdh_kdf_md:sha256 .Ve .SH "BUGS" .IX Header "BUGS" The \s-1MIME\s0 parser isn't very clever: it seems to handle most messages that I've thrown at it but it may choke on others. .PP The code currently will only write out the signer's certificate to a file: if the signer has a separate encryption certificate this must be manually extracted. There should be some heuristic that determines the correct encryption certificate. .PP Ideally a database should be maintained of a certificates for each email address. .PP The code doesn't currently take note of the permitted symmetric encryption algorithms as supplied in the SMIMECapabilities signed attribute. this means the user has to manually include the correct encryption algorithm. It should store the list of permitted ciphers in a database and only use those. .PP No revocation checking is done on the signer's certificate. .PP The \fB\-binary\fR option does not work correctly when processing text input which (contrary to the S/MIME specification) uses \s-1LF\s0 rather than \s-1CRLF\s0 line endings. .SH "HISTORY" .IX Header "HISTORY" The use of multiple \fB\-signer\fR options and the \fB\-resign\fR command were first added in OpenSSL 1.0.0. .PP The \fBkeyopt\fR option was added in OpenSSL 1.0.2. .PP Support for RSA-OAEP and RSA-PSS was added in OpenSSL 1.0.2. .PP The use of non-RSA keys with \fB\-encrypt\fR and \fB\-decrypt\fR was added in OpenSSL 1.0.2. .PP The \-no_alt_chains option was added in OpenSSL 1.0.2b. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2008\-2022 The OpenSSL Project Authors.

When generating a private key various symbols will be output to indicate the progress of the generation. A \fB.\fR represents each number which has passed an initial sieve test, \fB+\fR means a number has passed a single round of the Miller-Rabin primality test, \fB*\fR means the current prime starts a regenerating progress due to some failed tests. A newline means that the number has passed all the prime tests (the actual number depends on the key size). .PP Because key generation is a random process the time taken to generate a key may vary somewhat. But in general, more primes lead to less generation time of a key. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBgendsa\fR\|(1) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2021 The OpenSSL Project Authors.

It can be used to print out requests and responses, create requests and send queries to an \s-1OCSP\s0 responder and behave like a mini \s-1OCSP\s0 server itself. .SH "OPTIONS" .IX Header "OPTIONS" This command operates as either a client or a server. The options are described below, divided into those two modes. .SS "\s-1OCSP\s0 Client Options" .IX Subsection "OCSP Client Options" .IP "\fB\-help\fR" 4 .IX Item "-help" Print out a usage message. .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" specify output filename, default is standard output. .IP "\fB\-issuer filename\fR" 4 .IX Item "-issuer filename" This specifies the current issuer certificate. This option can be used multiple times. The certificate specified in \fBfilename\fR must be in \&\s-1PEM\s0 format. This option \fB\s-1MUST\s0\fR come before any \fB\-cert\fR options. .IP "\fB\-cert filename\fR" 4 .IX Item "-cert filename" Add the certificate \fBfilename\fR to the request. The issuer certificate is taken from the previous \fBissuer\fR option, or an error occurs if no issuer certificate is specified. .IP "\fB\-serial num\fR" 4 .IX Item "-serial num" Same as the \fBcert\fR option except the certificate with serial number \&\fBnum\fR is added to the request. The serial number is interpreted as a decimal integer unless preceded by \fB0x\fR. Negative integers can also be specified by preceding the value by a \fB\-\fR sign. .IP "\fB\-signer filename\fR, \fB\-signkey filename\fR" 4 .IX Item "-signer filename, -signkey filename" Sign the \s-1OCSP\s0 request using the certificate specified in the \fBsigner\fR option and the private key specified by the \fBsignkey\fR option. If the \fBsignkey\fR option is not present then the private key is read from the same file as the certificate. If neither option is specified then the \s-1OCSP\s0 request is not signed. .IP "\fB\-sign_other filename\fR" 4 .IX Item "-sign_other filename" Additional certificates to include in the signed request. .IP "\fB\-nonce\fR, \fB\-no_nonce\fR" 4 .IX Item "-nonce, -no_nonce" Add an \s-1OCSP\s0 nonce extension to a request or disable \s-1OCSP\s0 nonce addition. Normally if an \s-1OCSP\s0 request is input using the \fBreqin\fR option no nonce is added: using the \fBnonce\fR option will force addition of a nonce. If an \s-1OCSP\s0 request is being created (using \fBcert\fR and \fBserial\fR options) a nonce is automatically added specifying \fBno_nonce\fR overrides this. .IP "\fB\-req_text\fR, \fB\-resp_text\fR, \fB\-text\fR" 4 .IX Item "-req_text, -resp_text, -text" Print out the text form of the \s-1OCSP\s0 request, response or both respectively. .IP "\fB\-reqout file\fR, \fB\-respout file\fR" 4 .IX Item "-reqout file, -respout file" Write out the \s-1DER\s0 encoded certificate request or response to \fBfile\fR. .IP "\fB\-reqin file\fR, \fB\-respin file\fR" 4 .IX Item "-reqin file, -respin file" Read \s-1OCSP\s0 request or response file from \fBfile\fR. These option are ignored if \s-1OCSP\s0 request or response creation is implied by other options (for example with \fBserial\fR, \fBcert\fR and \fBhost\fR options). .IP "\fB\-url responder_url\fR" 4 .IX Item "-url responder_url" Specify the responder \s-1URL.\s0 Both \s-1HTTP\s0 and \s-1HTTPS\s0 (\s-1SSL/TLS\s0) URLs can be specified. .IP "\fB\-host hostname:port\fR, \fB\-path pathname\fR" 4 .IX Item "-host hostname:port, -path pathname" If the \fBhost\fR option is present then the \s-1OCSP\s0 request is sent to the host \&\fBhostname\fR on port \fBport\fR. \fBpath\fR specifies the \s-1HTTP\s0 pathname to use or \*(L"/\*(R" by default. This is equivalent to specifying \fB\-url\fR with scheme http:// and the given hostname, port, and pathname. .IP "\fB\-header name=value\fR" 4 .IX Item "-header name=value" Adds the header \fBname\fR with the specified \fBvalue\fR to the \s-1OCSP\s0 request that is sent to the responder. This may be repeated. .IP "\fB\-timeout seconds\fR" 4 .IX Item "-timeout seconds" Connection timeout to the \s-1OCSP\s0 responder in seconds. On \s-1POSIX\s0 systems, when running as an \s-1OCSP\s0 responder, this option also limits the time that the responder is willing to wait for the client request. This time is measured from the time the responder accepts the connection until the complete request is received. .IP "\fB\-multi process-count\fR" 4 .IX Item "-multi process-count" Run the specified number of \s-1OCSP\s0 responder child processes, with the parent process respawning child processes as needed. Child processes will detect changes in the \s-1CA\s0 index file and automatically reload it. When running as a responder \fB\-timeout\fR option is recommended to limit the time each child is willing to wait for the client's \s-1OCSP\s0 response. This option is available on \s-1POSIX\s0 systems (that support the \fBfork()\fR and other required unix system-calls). .IP "\fB\-CAfile file\fR, \fB\-CApath pathname\fR" 4 .IX Item "-CAfile file, -CApath pathname" File or pathname containing trusted \s-1CA\s0 certificates. These are used to verify the signature on the \s-1OCSP\s0 response. .IP "\fB\-no\-CAfile\fR" 4 .IX Item "-no-CAfile" Do not load the trusted \s-1CA\s0 certificates from the default file location .IP "\fB\-no\-CApath\fR" 4 .IX Item "-no-CApath" Do not load the trusted \s-1CA\s0 certificates from the default directory location .IP "\fB\-attime\fR, \fB\-check_ss_sig\fR, \fB\-crl_check\fR, \fB\-crl_check_all\fR, \fB\-explicit_policy\fR, \fB\-extended_crl\fR, \fB\-ignore_critical\fR, \fB\-inhibit_any\fR, \fB\-inhibit_map\fR, \fB\-no_alt_chains\fR, \fB\-no_check_time\fR, \fB\-partial_chain\fR, \fB\-policy\fR, \fB\-policy_check\fR, \fB\-policy_print\fR, \fB\-purpose\fR, \fB\-suiteB_128\fR, \fB\-suiteB_128_only\fR, \fB\-suiteB_192\fR, \fB\-trusted_first\fR, \fB\-use_deltas\fR, \fB\-auth_level\fR, \fB\-verify_depth\fR, \fB\-verify_email\fR, \fB\-verify_hostname\fR, \fB\-verify_ip\fR, \fB\-verify_name\fR, \fB\-x509_strict\fR" 4 .IX Item "-attime, -check_ss_sig, -crl_check, -crl_check_all, -explicit_policy, -extended_crl, -ignore_critical, -inhibit_any, -inhibit_map, -no_alt_chains, -no_check_time, -partial_chain, -policy, -policy_check, -policy_print, -purpose, -suiteB_128, -suiteB_128_only, -suiteB_192, -trusted_first, -use_deltas, -auth_level, -verify_depth, -verify_email, -verify_hostname, -verify_ip, -verify_name, -x509_strict" Set different certificate verification options. See \fBverify\fR\|(1) manual page for details. .IP "\fB\-verify_other file\fR" 4 .IX Item "-verify_other file" File containing additional certificates to search when attempting to locate the \s-1OCSP\s0 response signing certificate. Some responders omit the actual signer's certificate from the response: this option can be used to supply the necessary certificate in such cases. .IP "\fB\-trust_other\fR" 4 .IX Item "-trust_other" The certificates specified by the \fB\-verify_other\fR option should be explicitly trusted and no additional checks will be performed on them. This is useful when the complete responder certificate chain is not available or trusting a root \s-1CA\s0 is not appropriate. .IP "\fB\-VAfile file\fR" 4 .IX Item "-VAfile file" File containing explicitly trusted responder certificates. Equivalent to the \&\fB\-verify_other\fR and \fB\-trust_other\fR options. .IP "\fB\-noverify\fR" 4 .IX Item "-noverify" Don't attempt to verify the \s-1OCSP\s0 response signature or the nonce values. This option will normally only be used for debugging since it disables all verification of the responders certificate. .IP "\fB\-no_intern\fR" 4 .IX Item "-no_intern" Ignore certificates contained in the \s-1OCSP\s0 response when searching for the signers certificate. With this option the signers certificate must be specified with either the \fB\-verify_other\fR or \fB\-VAfile\fR options. .IP "\fB\-no_signature_verify\fR" 4 .IX Item "-no_signature_verify" Don't check the signature on the \s-1OCSP\s0 response. Since this option tolerates invalid signatures on \s-1OCSP\s0 responses it will normally only be used for testing purposes. .IP "\fB\-no_cert_verify\fR" 4 .IX Item "-no_cert_verify" Don't verify the \s-1OCSP\s0 response signers certificate at all. Since this option allows the \s-1OCSP\s0 response to be signed by any certificate it should only be used for testing purposes. .IP "\fB\-no_chain\fR" 4 .IX Item "-no_chain" Do not use certificates in the response as additional untrusted \s-1CA\s0 certificates. .IP "\fB\-no_explicit\fR" 4 .IX Item "-no_explicit" Do not explicitly trust the root \s-1CA\s0 if it is set to be trusted for \s-1OCSP\s0 signing. .IP "\fB\-no_cert_checks\fR" 4 .IX Item "-no_cert_checks" Don't perform any additional checks on the \s-1OCSP\s0 response signers certificate. That is do not make any checks to see if the signers certificate is authorised to provide the necessary status information: as a result this option should only be used for testing purposes. .IP "\fB\-validity_period nsec\fR, \fB\-status_age age\fR" 4 .IX Item "-validity_period nsec, -status_age age" These options specify the range of times, in seconds, which will be tolerated in an \s-1OCSP\s0 response. Each certificate status response includes a \fBnotBefore\fR time and an optional \fBnotAfter\fR time. The current time should fall between these two values, but the interval between the two times may be only a few seconds. In practice the \s-1OCSP\s0 responder and clients clocks may not be precisely synchronised and so such a check may fail. To avoid this the \&\fB\-validity_period\fR option can be used to specify an acceptable error range in seconds, the default value is 5 minutes. .Sp If the \fBnotAfter\fR time is omitted from a response then this means that new status information is immediately available. In this case the age of the \&\fBnotBefore\fR field is checked to see it is not older than \fBage\fR seconds old.

When acting as an \s-1OCSP\s0 responder, continue running instead of terminating upon receiving a malformed request. .IP "\fB\-nrequest number\fR" 4 .IX Item "-nrequest number" The \s-1OCSP\s0 server will exit after receiving \fBnumber\fR requests, default unlimited. .IP "\fB\-nmin minutes\fR, \fB\-ndays days\fR" 4 .IX Item "-nmin minutes, -ndays days" Number of minutes or days when fresh revocation information is available: used in the \fBnextUpdate\fR field. If neither option is present then the \&\fBnextUpdate\fR field is omitted meaning fresh revocation information is immediately available. .SH "OCSP Response verification." .IX Header "OCSP Response verification." \&\s-1OCSP\s0 Response follows the rules specified in \s-1RFC2560.\s0 .PP Initially the \s-1OCSP\s0 responder certificate is located and the signature on the \s-1OCSP\s0 request checked using the responder certificate's public key. .PP Then a normal certificate verify is performed on the \s-1OCSP\s0 responder certificate building up a certificate chain in the process. The locations of the trusted certificates used to build the chain can be specified by the \fBCAfile\fR and \fBCApath\fR options or they will be looked for in the standard OpenSSL certificates directory. .PP If the initial verify fails then the \s-1OCSP\s0 verify process halts with an error. .PP Otherwise the issuing \s-1CA\s0 certificate in the request is compared to the \s-1OCSP\s0 responder certificate: if there is a match then the \s-1OCSP\s0 verify succeeds. .PP Otherwise the \s-1OCSP\s0 responder certificate's \s-1CA\s0 is checked against the issuing \&\s-1CA\s0 certificate in the request. If there is a match and the OCSPSigning extended key usage is present in the \s-1OCSP\s0 responder certificate then the \&\s-1OCSP\s0 verify succeeds. .PP Otherwise, if \fB\-no_explicit\fR is \fBnot\fR set the root \s-1CA\s0 of the \s-1OCSP\s0 responders \&\s-1CA\s0 is checked to see if it is trusted for \s-1OCSP\s0 signing. If it is the \s-1OCSP\s0 verify succeeds. .PP If none of these checks is successful then the \s-1OCSP\s0 verify fails. .PP What this effectively means if that if the \s-1OCSP\s0 responder certificate is authorised directly by the \s-1CA\s0 it is issuing revocation information about (and it is correctly configured) then verification will succeed. .PP If the \s-1OCSP\s0 responder is a \*(L"global responder\*(R" which can give details about multiple CAs and has its own separate certificate chain then its root \&\s-1CA\s0 can be trusted for \s-1OCSP\s0 signing. For example: .PP .Vb 1 \& openssl x509 \-in ocspCA.pem \-addtrust OCSPSigning \-out trustedCA.pem .Ve .PP Alternatively the responder certificate itself can be explicitly trusted with the \fB\-VAfile\fR option. .SH "NOTES" .IX Header "NOTES" As noted, most of the verify options are for testing or debugging purposes. Normally only the \fB\-CApath\fR, \fB\-CAfile\fR and (if the responder is a 'global \&\s-1VA\s0') \fB\-VAfile\fR options need to be used. .PP The \s-1OCSP\s0 server is only useful for test and demonstration purposes: it is not really usable as a full \s-1OCSP\s0 responder. It contains only a very simple \s-1HTTP\s0 request handling and can only handle the \s-1POST\s0 form of \s-1OCSP\s0 queries. It also handles requests serially meaning it cannot respond to new requests until it has processed the current one. The text index file format of revocation is also inefficient for large quantities of revocation data. .PP It is possible to run the \fBocsp\fR application in responder mode via a \s-1CGI\s0 script using the \fBreqin\fR and \fBrespout\fR options. .SH "EXAMPLES" .IX Header "EXAMPLES" Create an \s-1OCSP\s0 request and write it to a file: .PP .Vb 1 \& openssl ocsp \-issuer issuer.pem \-cert c1.pem \-cert c2.pem \-reqout req.der .Ve .PP Send a query to an \s-1OCSP\s0 responder with \s-1URL\s0 http://ocsp.myhost.com/ save the response to a file, print it out in text form, and verify the response: .PP .Vb 2 \& openssl ocsp \-issuer issuer.pem \-cert c1.pem \-cert c2.pem \e \& \-url http://ocsp.myhost.com/ \-resp_text \-respout resp.der .Ve .PP Read in an \s-1OCSP\s0 response and print out text form: .PP .Vb 1 \& openssl ocsp \-respin resp.der \-text \-noverify .Ve .PP \&\s-1OCSP\s0 server on port 8888 using a standard \fBca\fR configuration, and a separate responder certificate.

It is intended to simplify the process of certificate creation and management by the use of some simple options. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB?\fR, \fB\-h\fR, \fB\-help\fR" 4 .IX Item "?, -h, -help" Prints a usage message. .IP "\fB\-newcert\fR" 4 .IX Item "-newcert" Creates a new self signed certificate. The private key is written to the file \&\*(L"newkey.pem\*(R" and the request written to the file \*(L"newreq.pem\*(R". This argument invokes \fBopenssl req\fR command. .IP "\fB\-newreq\fR" 4 .IX Item "-newreq" Creates a new certificate request. The private key is written to the file \&\*(L"newkey.pem\*(R" and the request written to the file \*(L"newreq.pem\*(R". Executes \fBopenssl req\fR command below the hood. .IP "\fB\-newreq\-nodes\fR" 4 .IX Item "-newreq-nodes" Is like \fB\-newreq\fR except that the private key will not be encrypted. Uses \fBopenssl req\fR command. .IP "\fB\-newca\fR" 4 .IX Item "-newca" Creates a new \s-1CA\s0 hierarchy for use with the \fBca\fR program (or the \fB\-signcert\fR and \fB\-xsign\fR options). The user is prompted to enter the filename of the \s-1CA\s0 certificates (which should also contain the private key) or by hitting \s-1ENTER\s0 details of the \s-1CA\s0 will be prompted for. The relevant files and directories are created in a directory called \*(L"demoCA\*(R" in the current directory. \&\fBopenssl req\fR and \fBopenssl ca\fR commands are get invoked. .IP "\fB\-pkcs12\fR" 4 .IX Item "-pkcs12" Create a PKCS#12 file containing the user certificate, private key and \s-1CA\s0 certificate. It expects the user certificate and private key to be in the file \*(L"newcert.pem\*(R" and the \s-1CA\s0 certificate to be in the file demoCA/cacert.pem, it creates a file \*(L"newcert.p12\*(R". This command can thus be called after the \&\fB\-sign\fR option. The PKCS#12 file can be imported directly into a browser. If there is an additional argument on the command line it will be used as the \&\*(L"friendly name\*(R" for the certificate (which is typically displayed in the browser list box), otherwise the name \*(L"My Certificate\*(R" is used. Delegates work to \fBopenssl pkcs12\fR command. .IP "\fB\-sign\fR, \fB\-signcert\fR, \fB\-xsign\fR" 4 .IX Item "-sign, -signcert, -xsign" Calls the \fBca\fR program to sign a certificate request. It expects the request to be in the file \*(L"newreq.pem\*(R". The new certificate is written to the file \&\*(L"newcert.pem\*(R" except in the case of the \fB\-xsign\fR option when it is written to standard output. Leverages \fBopenssl ca\fR command. .IP "\fB\-signCA\fR" 4 .IX Item "-signCA" This option is the same as the \fB\-sign\fR option except it uses the configuration file section \fBv3_ca\fR and so makes the signed request a valid \s-1CA\s0 certificate. This is useful when creating intermediate \s-1CA\s0 from a root \s-1CA.\s0 Extra params are passed on to \fBopenssl ca\fR command. .IP "\fB\-signcert\fR" 4 .IX Item "-signcert" This option is the same as \fB\-sign\fR except it expects a self signed certificate to be present in the file \*(L"newreq.pem\*(R". Extra params are passed on to \fBopenssl x509\fR and \fBopenssl ca\fR commands. .IP "\fB\-crl\fR" 4 .IX Item "-crl" Generate a \s-1CRL.\s0 Executes \fBopenssl ca\fR command. .IP "\fB\-revoke certfile [reason]\fR" 4 .IX Item "-revoke certfile [reason]" Revoke the certificate contained in the specified \fBcertfile\fR. An optional reason may be specified, and must be one of: \fBunspecified\fR, \&\fBkeyCompromise\fR, \fBCACompromise\fR, \fBaffiliationChanged\fR, \fBsuperseded\fR, \&\fBcessationOfOperation\fR, \fBcertificateHold\fR, or \fBremoveFromCRL\fR. Leverages \fBopenssl ca\fR command. .IP "\fB\-verify\fR" 4 .IX Item "-verify" Verifies certificates against the \s-1CA\s0 certificate for \*(L"demoCA\*(R". If no certificates are specified on the command line it tries to verify the file \&\*(L"newcert.pem\*(R". Invokes \fBopenssl verify\fR command. .IP "\fB\-extra\-req\fR | \fB\-extra\-ca\fR | \fB\-extra\-pkcs12\fR | \fB\-extra\-x509\fR | \fB\-extra\-verify\fR <extra\-params>" 4 .IX Item "-extra-req | -extra-ca | -extra-pkcs12 | -extra-x509 | -extra-verify <extra-params>" The purpose of these parameters is to allow optional parameters to be supplied to \fBopenssl\fR that this command executes. The \fB\-extra\-cmd\fR are specific to the option being used and the \fBopenssl\fR command getting invoked. For example when this command invokes \fBopenssl req\fR extra parameters can be passed on with the \fB\-extra\-req\fR parameter.

The following example shows the steps that would typically be taken. .PP Create some \s-1DSA\s0 parameters: .PP .Vb 1 \& openssl dsaparam \-out dsap.pem 1024 .Ve .PP Create a \s-1DSA CA\s0 certificate and private key: .PP .Vb 1 \& openssl req \-x509 \-newkey dsa:dsap.pem \-keyout cacert.pem \-out cacert.pem .Ve .PP Create the \s-1CA\s0 directories and files: .PP .Vb 1 \& CA.pl \-newca .Ve .PP enter cacert.pem when prompted for the \s-1CA\s0 filename. .PP Create a \s-1DSA\s0 certificate request and private key (a different set of parameters can optionally be created first): .PP .Vb 1 \& openssl req \-out newreq.pem \-newkey dsa:dsap.pem .Ve .PP Sign the request: .PP .Vb 1 \& CA.pl \-sign .Ve .SH "NOTES" .IX Header "NOTES" Most of the filenames mentioned can be modified by editing the \fB\s-1CA\s0.pl\fR script. .PP If the demoCA directory already exists then the \fB\-newca\fR command will not overwrite it and will do nothing. This can happen if a previous call using the \fB\-newca\fR option terminated abnormally. To get the correct behaviour delete the demoCA directory if it already exists. .PP Under some environments it may not be possible to run the \fB\s-1CA\s0.pl\fR script directly (for example Win32) and the default configuration file location may be wrong. In this case the command: .PP .Vb 1 \& perl \-S CA.pl .Ve .PP can be used and the \fB\s-1OPENSSL_CONF\s0\fR environment variable changed to point to the correct path of the configuration file. .PP The script is intended as a simple front end for the \fBopenssl\fR program for use by a beginner. Its behaviour isn't always what is wanted.

It measures the number of connections within a given timeframe, the amount of data transferred (if any), and calculates the average time spent for one connection. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-help\fR" 4 .IX Item "-help" Print out a usage message. .IP "\fB\-connect host:port\fR" 4 .IX Item "-connect host:port" This specifies the host and optional port to connect to. .IP "\fB\-www page\fR" 4 .IX Item "-www page" This specifies the page to \s-1GET\s0 from the server. A value of '/' gets the index.htm[l] page. If this parameter is not specified, then \fBs_time\fR will only perform the handshake to establish \s-1SSL\s0 connections but not transfer any payload data. .IP "\fB\-cert certname\fR" 4 .IX Item "-cert certname" The certificate to use, if one is requested by the server. The default is not to use a certificate. The file is in \s-1PEM\s0 format. .IP "\fB\-key keyfile\fR" 4 .IX Item "-key keyfile" The private key to use. If not specified then the certificate file will be used. The file is in \s-1PEM\s0 format. .IP "\fB\-verify depth\fR" 4 .IX Item "-verify depth" The verify depth to use. This specifies the maximum length of the server certificate chain and turns on server certificate verification. Currently the verify operation continues after errors so all the problems with a certificate chain can be seen. As a side effect the connection will never fail due to a server certificate verify failure. .IP "\fB\-nameopt option\fR" 4 .IX Item "-nameopt option" Option which determines how the subject or issuer names are displayed. The \&\fBoption\fR argument can be a single option or multiple options separated by commas. Alternatively the \fB\-nameopt\fR switch may be used more than once to set multiple options. See the \fBx509\fR\|(1) manual page for details. .IP "\fB\-CApath directory\fR" 4 .IX Item "-CApath directory" The directory to use for server certificate verification. This directory must be in \*(L"hash format\*(R", see \fBverify\fR for more information. These are also used when building the client certificate chain. .IP "\fB\-CAfile file\fR" 4 .IX Item "-CAfile file" A file containing trusted certificates to use during server authentication and to use when attempting to build the client certificate chain. .IP "\fB\-no\-CAfile\fR" 4 .IX Item "-no-CAfile" Do not load the trusted \s-1CA\s0 certificates from the default file location .IP "\fB\-no\-CApath\fR" 4 .IX Item "-no-CApath" Do not load the trusted \s-1CA\s0 certificates from the default directory location .IP "\fB\-new\fR" 4 .IX Item "-new" Performs the timing test using a new session \s-1ID\s0 for each connection. If neither \fB\-new\fR nor \fB\-reuse\fR are specified, they are both on by default and executed in sequence. .IP "\fB\-reuse\fR" 4 .IX Item "-reuse" Performs the timing test using the same session \s-1ID\s0; this can be used as a test that session caching is working. If neither \fB\-new\fR nor \fB\-reuse\fR are specified, they are both on by default and executed in sequence. .IP "\fB\-ssl3\fR" 4 .IX Item "-ssl3" This option disables the use of \s-1SSL\s0 version 3. By default the initial handshake uses a method which should be compatible with all servers and permit them to use \s-1SSL\s0 v3 or \s-1TLS\s0 as appropriate. .Sp The timing program is not as rich in options to turn protocols on and off as the \fBs_client\fR\|(1) program and may not connect to all servers. Unfortunately there are a lot of ancient and broken servers in use which cannot handle this technique and will fail to connect. Some servers only work if \s-1TLS\s0 is turned off with the \fB\-ssl3\fR option. .Sp Note that this option may not be available, depending on how OpenSSL was built. .IP "\fB\-bugs\fR" 4 .IX Item "-bugs" There are several known bugs in \s-1SSL\s0 and \s-1TLS\s0 implementations. Adding this option enables various workarounds. .IP "\fB\-cipher cipherlist\fR" 4 .IX Item "-cipher cipherlist" This allows the TLSv1.2 and below cipher list sent by the client to be modified. This list will be combined with any TLSv1.3 ciphersuites that have been configured. Although the server determines which cipher suite is used it should take the first supported cipher in the list sent by the client. See \&\fBciphers\fR\|(1) for more information. .IP "\fB\-ciphersuites val\fR" 4 .IX Item "-ciphersuites val" This allows the TLSv1.3 ciphersuites sent by the client to be modified. This list will be combined with any TLSv1.2 and below ciphersuites that have been configured. Although the server determines which cipher suite is used it should take the first supported cipher in the list sent by the client. See \&\fBciphers\fR\|(1) for more information. The format for this list is a simple colon (\*(L":\*(R") separated list of TLSv1.3 ciphersuite names. .IP "\fB\-time length\fR" 4 .IX Item "-time length" Specifies how long (in seconds) \fBs_time\fR should establish connections and optionally transfer payload data from a server. Server and client performance and the link speed determine how many connections \fBs_time\fR can establish. .SH "NOTES" .IX Header "NOTES" \&\fBs_time\fR can be used to measure the performance of an \s-1SSL\s0 connection. To connect to an \s-1SSL HTTP\s0 server and get the default page the command .PP .Vb 1 \& openssl s_time \-connect servername:443 \-www / \-CApath yourdir \-CAfile yourfile.pem \-cipher commoncipher [\-ssl3] .Ve .PP would typically be used (https uses port 443). 'commoncipher' is a cipher to which both client and server can agree, see the \fBciphers\fR\|(1) command for details. .PP If the handshake fails then there are several possible causes, if it is nothing obvious like no client certificate then the \fB\-bugs\fR and \&\fB\-ssl3\fR options can be tried in case it is a buggy server. In particular you should play with these options \fBbefore\fR submitting a bug report to an OpenSSL mailing list. .PP A frequent problem when attempting to get client certificates working is that a web client complains it has no certificates or gives an empty list to choose from. This is normally because the server is not sending the clients certificate authority in its \*(L"acceptable \s-1CA\s0 list\*(R" when it requests a certificate. By using \fBs_client\fR\|(1) the \s-1CA\s0 list can be viewed and checked. However, some servers only request client authentication after a specific \s-1URL\s0 is requested. To obtain the list in this case it is necessary to use the \fB\-prexit\fR option of \fBs_client\fR\|(1) and send an \s-1HTTP\s0 request for an appropriate page. .PP If a certificate is specified on the command line using the \fB\-cert\fR option it will not be used unless the server specifically requests a client certificate. Therefore, merely including a client certificate on the command line is no guarantee that the certificate works. .SH "BUGS" .IX Header "BUGS" Because this program does not have all the options of the \&\fBs_client\fR\|(1) program to turn protocols on and off, you may not be able to measure the performance of all protocols with all servers. .PP The \fB\-verify\fR option should really exit if the server verification fails. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBs_client\fR\|(1), \fBs_server\fR\|(1), \fBciphers\fR\|(1) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2004\-2020 The OpenSSL Project Authors.

This list will be combined with any TLSv1.3 ciphersuites that have been configured. If it is not included then the default cipher list will be used. The format is described below. .SH "CIPHER LIST FORMAT" .IX Header "CIPHER LIST FORMAT" The cipher list consists of one or more \fIcipher strings\fR separated by colons. Commas or spaces are also acceptable separators but colons are normally used. .PP The actual cipher string can take several different forms. .PP It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR. .PP It can represent a list of cipher suites containing a certain algorithm, or cipher suites of a certain type. For example \fB\s-1SHA1\s0\fR represents all ciphers suites using the digest algorithm \s-1SHA1\s0 and \fBSSLv3\fR represents all \s-1SSL\s0 v3 algorithms. .PP Lists of cipher suites can be combined in a single cipher string using the \&\fB+\fR character. This is used as a logical \fBand\fR operation. For example \&\fB\s-1SHA1+DES\s0\fR represents all cipher suites containing the \s-1SHA1\s0 \fBand\fR the \s-1DES\s0 algorithms. .PP Each cipher string can be optionally preceded by the characters \fB!\fR, \&\fB\-\fR or \fB+\fR. .PP If \fB!\fR is used then the ciphers are permanently deleted from the list. The ciphers deleted can never reappear in the list even if they are explicitly stated. .PP If \fB\-\fR is used then the ciphers are deleted from the list, but some or all of the ciphers can be added again by later options. .PP If \fB+\fR is used then the ciphers are moved to the end of the list. This option doesn't add any new ciphers it just moves matching existing ones. .PP If none of these characters is present then the string is just interpreted as a list of ciphers to be appended to the current preference list. If the list includes any ciphers already present they will be ignored: that is they will not moved to the end of the list. .PP The cipher string \fB\f(CB@STRENGTH\fB\fR can be used at any point to sort the current cipher list in order of encryption algorithm key length. .PP The cipher string \fB\f(CB@SECLEVEL\fB=n\fR can be used at any point to set the security level to \fBn\fR, which should be a number between zero and five, inclusive. See SSL_CTX_set_security_level for a description of what each level means. .PP The cipher list can be prefixed with the \fB\s-1DEFAULT\s0\fR keyword, which enables the default cipher list as defined below. Unlike cipher strings, this prefix may not be combined with other strings using \fB+\fR character. For example, \fB\s-1DEFAULT+DES\s0\fR is not valid. .PP The content of the default list is determined at compile time and normally corresponds to \fB\s-1ALL:\s0!COMPLEMENTOFDEFAULT:!eNULL\fR. .SH "CIPHER STRINGS" .IX Header "CIPHER STRINGS" The following is a list of all permitted cipher strings and their meanings. .IP "\fB\s-1COMPLEMENTOFDEFAULT\s0\fR" 4 .IX Item "COMPLEMENTOFDEFAULT" The ciphers included in \fB\s-1ALL\s0\fR, but not enabled by default.

Optional; for a description of the default value, see \*(L"\s-1COMMAND SUMMARY\*(R"\s0 in \fBopenssl\fR\|(1). .IP "\fB\-name section\fR" 4 .IX Item "-name section" Specifies the configuration file section to use (overrides \&\fBdefault_ca\fR in the \fBca\fR section). .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" An input filename containing a single certificate request to be signed by the \s-1CA.\s0 .IP "\fB\-ss_cert filename\fR" 4 .IX Item "-ss_cert filename" A single self-signed certificate to be signed by the \s-1CA.\s0 .IP "\fB\-spkac filename\fR" 4 .IX Item "-spkac filename" A file containing a single Netscape signed public key and challenge and additional field values to be signed by the \s-1CA.\s0 See the \fB\s-1SPKAC FORMAT\s0\fR section for information on the required input and output format. .IP "\fB\-infiles\fR" 4 .IX Item "-infiles" If present this should be the last option, all subsequent arguments are taken as the names of files containing certificate requests. .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" The output file to output certificates to. The default is standard output. The certificate details will also be printed out to this file in \s-1PEM\s0 format (except that \fB\-spkac\fR outputs \s-1DER\s0 format). .IP "\fB\-outdir directory\fR" 4 .IX Item "-outdir directory" The directory to output certificates to. The certificate will be written to a filename consisting of the serial number in hex with \&\*(L".pem\*(R" appended. .IP "\fB\-cert\fR" 4 .IX Item "-cert" The \s-1CA\s0 certificate file. .IP "\fB\-keyfile filename\fR" 4 .IX Item "-keyfile filename" The private key to sign requests with. .IP "\fB\-keyform PEM|DER\fR" 4 .IX Item "-keyform PEM|DER" The format of the data in the private key file. The default is \s-1PEM.\s0 .IP "\fB\-sigopt nm:v\fR" 4 .IX Item "-sigopt nm:v" Pass options to the signature algorithm during sign or verify operations. Names and values of these options are algorithm-specific. .IP "\fB\-key password\fR" 4 .IX Item "-key password" The password used to encrypt the private key. Since on some systems the command line arguments are visible (e.g. Unix with the 'ps' utility) this option should be used with caution. .IP "\fB\-selfsign\fR" 4 .IX Item "-selfsign" Indicates the issued certificates are to be signed with the key the certificate requests were signed with (given with \fB\-keyfile\fR). Certificate requests signed with a different key are ignored. If \&\fB\-spkac\fR, \fB\-ss_cert\fR or \fB\-gencrl\fR are given, \fB\-selfsign\fR is ignored. .Sp A consequence of using \fB\-selfsign\fR is that the self-signed certificate appears among the entries in the certificate database (see the configuration option \fBdatabase\fR), and uses the same serial number counter as all other certificates sign with the self-signed certificate. .IP "\fB\-passin arg\fR" 4 .IX Item "-passin arg" The key password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-notext\fR" 4 .IX Item "-notext" Don't output the text form of a certificate to the output file. .IP "\fB\-startdate date\fR" 4 .IX Item "-startdate date" This allows the start date to be explicitly set. The format of the date is \s-1YYMMDDHHMMSSZ\s0 (the same as an \s-1ASN1\s0 UTCTime structure), or \&\s-1YYYYMMDDHHMMSSZ\s0 (the same as an \s-1ASN1\s0 GeneralizedTime structure). In both formats, seconds \s-1SS\s0 and timezone Z must be present. .IP "\fB\-enddate date\fR" 4 .IX Item "-enddate date" This allows the expiry date to be explicitly set. The format of the date is \s-1YYMMDDHHMMSSZ\s0 (the same as an \s-1ASN1\s0 UTCTime structure), or \&\s-1YYYYMMDDHHMMSSZ\s0 (the same as an \s-1ASN1\s0 GeneralizedTime structure). In both formats, seconds \s-1SS\s0 and timezone Z must be present. .IP "\fB\-days arg\fR" 4 .IX Item "-days arg" The number of days to certify the certificate for. .IP "\fB\-md alg\fR" 4 .IX Item "-md alg" The message digest to use. Any digest supported by the OpenSSL \fBdgst\fR command can be used. For signing algorithms that do not support a digest (i.e. Ed25519 and Ed448) any message digest that is set is ignored. This option also applies to CRLs. .IP "\fB\-policy arg\fR" 4 .IX Item "-policy arg" This option defines the \s-1CA\s0 \*(L"policy\*(R" to use. This is a section in the configuration file which decides which fields should be mandatory or match the \s-1CA\s0 certificate. Check out the \fB\s-1POLICY FORMAT\s0\fR section for more information. .IP "\fB\-msie_hack\fR" 4 .IX Item "-msie_hack" This is a deprecated option to make \fBca\fR work with very old versions of the \s-1IE\s0 certificate enrollment control \*(L"certenr3\*(R". It used UniversalStrings for almost everything. Since the old control has various security bugs its use is strongly discouraged. .IP "\fB\-preserveDN\fR" 4 .IX Item "-preserveDN" Normally the \s-1DN\s0 order of a certificate is the same as the order of the fields in the relevant policy section. When this option is set the order is the same as the request. This is largely for compatibility with the older \s-1IE\s0 enrollment control which would only accept certificates if their DNs match the order of the request. This is not needed for Xenroll. .IP "\fB\-noemailDN\fR" 4 .IX Item "-noemailDN" The \s-1DN\s0 of a certificate can contain the \s-1EMAIL\s0 field if present in the request \s-1DN,\s0 however, it is good policy just having the e\-mail set into the altName extension of the certificate. When this option is set the \&\s-1EMAIL\s0 field is removed from the certificate' subject and set only in the, eventually present, extensions. The \fBemail_in_dn\fR keyword can be used in the configuration file to enable this behaviour. .IP "\fB\-batch\fR" 4 .IX Item "-batch" This sets the batch mode. In this mode no questions will be asked and all certificates will be certified automatically. .IP "\fB\-extensions section\fR" 4 .IX Item "-extensions section" The section of the configuration file containing certificate extensions to be added when a certificate is issued (defaults to \fBx509_extensions\fR unless the \fB\-extfile\fR option is used). If no extension section is present then, a V1 certificate is created. If the extension section is present (even if it is empty), then a V3 certificate is created. See the \&\fBx509v3_config\fR\|(5) manual page for details of the extension section format. .IP "\fB\-extfile file\fR" 4 .IX Item "-extfile file" An additional configuration file to read certificate extensions from (using the default section unless the \fB\-extensions\fR option is also used). .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBca\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. .IP "\fB\-subj arg\fR" 4 .IX Item "-subj arg" Supersedes subject name given in the request. The arg must be formatted as \fI/type0=value0/type1=value1/type2=...\fR. Keyword characters may be escaped by \e (backslash), and whitespace is retained. Empty values are permitted, but the corresponding type will not be included in the resulting certificate. .IP "\fB\-utf8\fR" 4 .IX Item "-utf8" This option causes field values to be interpreted as \s-1UTF8\s0 strings, by default they are interpreted as \s-1ASCII.\s0 This means that the field values, whether prompted from a terminal or obtained from a configuration file, must be valid \s-1UTF8\s0 strings. .IP "\fB\-create_serial\fR" 4 .IX Item "-create_serial" If reading serial from the text file as specified in the configuration fails, specifying this option creates a new random serial to be used as next serial number. To get random serial numbers, use the \fB\-rand_serial\fR flag instead; this should only be used for simple error-recovery. .IP "\fB\-rand_serial\fR" 4 .IX Item "-rand_serial" Generate a large random number to use as the serial number. This overrides any option or configuration to use a serial number file. .IP "\fB\-multivalue\-rdn\fR" 4 .IX Item "-multivalue-rdn" This option causes the \-subj argument to be interpreted with full support for multivalued RDNs. Example: .Sp \&\fI/DC=org/DC=OpenSSL/DC=users/UID=123456+CN=John Doe\fR .Sp If \-multi\-rdn is not used then the \s-1UID\s0 value is \fI123456+CN=John Doe\fR. .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .SH "CRL OPTIONS" .IX Header "CRL OPTIONS" .IP "\fB\-gencrl\fR" 4 .IX Item "-gencrl" This option generates a \s-1CRL\s0 based on information in the index file. .IP "\fB\-crldays num\fR" 4 .IX Item "-crldays num" The number of days before the next \s-1CRL\s0 is due. That is the days from now to place in the \s-1CRL\s0 nextUpdate field. .IP "\fB\-crlhours num\fR" 4 .IX Item "-crlhours num" The number of hours before the next \s-1CRL\s0 is due. .IP "\fB\-revoke filename\fR" 4 .IX Item "-revoke filename" A filename containing a certificate to revoke. .IP "\fB\-valid filename\fR" 4 .IX Item "-valid filename" A filename containing a certificate to add a Valid certificate entry. .IP "\fB\-status serial\fR" 4 .IX Item "-status serial" Displays the revocation status of the certificate with the specified serial number and exits. .IP "\fB\-updatedb\fR" 4 .IX Item "-updatedb" Updates the database index to purge expired certificates. .IP "\fB\-crl_reason reason\fR" 4 .IX Item "-crl_reason reason" Revocation reason, where \fBreason\fR is one of: \fBunspecified\fR, \fBkeyCompromise\fR, \&\fBCACompromise\fR, \fBaffiliationChanged\fR, \fBsuperseded\fR, \fBcessationOfOperation\fR, \&\fBcertificateHold\fR or \fBremoveFromCRL\fR. The matching of \fBreason\fR is case insensitive. Setting any revocation reason will make the \s-1CRL\s0 v2. .Sp In practice \fBremoveFromCRL\fR is not particularly useful because it is only used in delta CRLs which are not currently implemented. .IP "\fB\-crl_hold instruction\fR" 4 .IX Item "-crl_hold instruction" This sets the \s-1CRL\s0 revocation reason code to \fBcertificateHold\fR and the hold instruction to \fBinstruction\fR which must be an \s-1OID.\s0 Although any \s-1OID\s0 can be used only \fBholdInstructionNone\fR (the use of which is discouraged by \s-1RFC2459\s0) \&\fBholdInstructionCallIssuer\fR or \fBholdInstructionReject\fR will normally be used. .IP "\fB\-crl_compromise time\fR" 4 .IX Item "-crl_compromise time" This sets the revocation reason to \fBkeyCompromise\fR and the compromise time to \&\fBtime\fR. \fBtime\fR should be in GeneralizedTime format that is \fB\s-1YYYYMMDDHHMMSSZ\s0\fR. .IP "\fB\-crl_CA_compromise time\fR" 4 .IX Item "-crl_CA_compromise time" This is the same as \fBcrl_compromise\fR except the revocation reason is set to \&\fBCACompromise\fR. .IP "\fB\-crlexts section\fR" 4 .IX Item "-crlexts section" The section of the configuration file containing \s-1CRL\s0 extensions to include. If no \s-1CRL\s0 extension section is present then a V1 \s-1CRL\s0 is created, if the \s-1CRL\s0 extension section is present (even if it is empty) then a V2 \s-1CRL\s0 is created. The \s-1CRL\s0 extensions specified are \&\s-1CRL\s0 extensions and \fBnot\fR \s-1CRL\s0 entry extensions. It should be noted that some software (for example Netscape) can't handle V2 CRLs. See \&\fBx509v3_config\fR\|(5) manual page for details of the extension section format. .SH "CONFIGURATION FILE OPTIONS" .IX Header "CONFIGURATION FILE OPTIONS" The section of the configuration file containing options for \fBca\fR is found as follows: If the \fB\-name\fR command line option is used, then it names the section to be used. Otherwise the section to be used must be named in the \fBdefault_ca\fR option of the \fBca\fR section of the configuration file (or in the default section of the configuration file). Besides \fBdefault_ca\fR, the following options are read directly from the \fBca\fR section: \s-1RANDFILE\s0 preserve msie_hack With the exception of \fB\s-1RANDFILE\s0\fR, this is probably a bug and may change in future releases. .PP Many of the configuration file options are identical to command line options. Where the option is present in the configuration file and the command line the command line value is used. Where an option is described as mandatory then it must be present in the configuration file or the command line equivalent (if any) used. .IP "\fBoid_file\fR" 4 .IX Item "oid_file" This specifies a file containing additional \fB\s-1OBJECT IDENTIFIERS\s0\fR. Each line of the file should consist of the numerical form of the object identifier followed by white space then the short name followed by white space and finally the long name. .IP "\fBoid_section\fR" 4 .IX Item "oid_section" This specifies a section in the configuration file containing extra object identifiers. Each line should consist of the short name of the object identifier followed by \fB=\fR and the numerical form. The short and long names are the same when this option is used. .IP "\fBnew_certs_dir\fR" 4 .IX Item "new_certs_dir" The same as the \fB\-outdir\fR command line option. It specifies the directory where new certificates will be placed. Mandatory. .IP "\fBcertificate\fR" 4 .IX Item "certificate" The same as \fB\-cert\fR. It gives the file containing the \s-1CA\s0 certificate. Mandatory. .IP "\fBprivate_key\fR" 4 .IX Item "private_key" Same as the \fB\-keyfile\fR option. The file containing the \&\s-1CA\s0 private key. Mandatory. .IP "\fB\s-1RANDFILE\s0\fR" 4 .IX Item "RANDFILE" At startup the specified file is loaded into the random number generator, and at exit 256 bytes will be written to it. .IP "\fBdefault_days\fR" 4 .IX Item "default_days" The same as the \fB\-days\fR option. The number of days to certify a certificate for. .IP "\fBdefault_startdate\fR" 4 .IX Item "default_startdate" The same as the \fB\-startdate\fR option. The start date to certify a certificate for. If not set the current time is used. .IP "\fBdefault_enddate\fR" 4 .IX Item "default_enddate" The same as the \fB\-enddate\fR option. Either this option or \&\fBdefault_days\fR (or the command line equivalents) must be present. .IP "\fBdefault_crl_hours default_crl_days\fR" 4 .IX Item "default_crl_hours default_crl_days" The same as the \fB\-crlhours\fR and the \fB\-crldays\fR options. These will only be used if neither command line option is present. At least one of these must be present to generate a \s-1CRL.\s0 .IP "\fBdefault_md\fR" 4 .IX Item "default_md" The same as the \fB\-md\fR option. Mandatory except where the signing algorithm does not require a digest (i.e. Ed25519 and Ed448). .IP "\fBdatabase\fR" 4 .IX Item "database" The text database file to use. Mandatory. This file must be present though initially it will be empty. .IP "\fBunique_subject\fR" 4 .IX Item "unique_subject" If the value \fByes\fR is given, the valid certificate entries in the database must have unique subjects. if the value \fBno\fR is given, several valid certificate entries may have the exact same subject. The default value is \fByes\fR, to be compatible with older (pre 0.9.8) versions of OpenSSL. However, to make \s-1CA\s0 certificate roll-over easier, it's recommended to use the value \fBno\fR, especially if combined with the \fB\-selfsign\fR command line option. .Sp Note that it is valid in some circumstances for certificates to be created without any subject. In the case where there are multiple certificates without subjects this does not count as a duplicate. .IP "\fBserial\fR" 4 .IX Item "serial" A text file containing the next serial number to use in hex. Mandatory. This file must be present and contain a valid serial number. .IP "\fBcrlnumber\fR" 4 .IX Item "crlnumber" A text file containing the next \s-1CRL\s0 number to use in hex. The crl number will be inserted in the CRLs only if this file exists. If this file is present, it must contain a valid \s-1CRL\s0 number. .IP "\fBx509_extensions\fR" 4 .IX Item "x509_extensions" The same as \fB\-extensions\fR. .IP "\fBcrl_extensions\fR" 4 .IX Item "crl_extensions" The same as \fB\-crlexts\fR. .IP "\fBpreserve\fR" 4 .IX Item "preserve" The same as \fB\-preserveDN\fR .IP "\fBemail_in_dn\fR" 4 .IX Item "email_in_dn" The same as \fB\-noemailDN\fR. If you want the \s-1EMAIL\s0 field to be removed from the \s-1DN\s0 of the certificate simply set this to 'no'. If not present the default is to allow for the \s-1EMAIL\s0 filed in the certificate's \s-1DN.\s0 .IP "\fBmsie_hack\fR" 4 .IX Item "msie_hack" The same as \fB\-msie_hack\fR .IP "\fBpolicy\fR" 4 .IX Item "policy" The same as \fB\-policy\fR. Mandatory. See the \fB\s-1POLICY FORMAT\s0\fR section for more information. .IP "\fBname_opt\fR, \fBcert_opt\fR" 4 .IX Item "name_opt, cert_opt" These options allow the format used to display the certificate details when asking the user to confirm signing. All the options supported by the \fBx509\fR utilities \fB\-nameopt\fR and \fB\-certopt\fR switches can be used here, except the \fBno_signame\fR and \fBno_sigdump\fR are permanently set and cannot be disabled (this is because the certificate signature cannot be displayed because the certificate has not been signed at this point). .Sp For convenience the values \fBca_default\fR are accepted by both to produce a reasonable output. .Sp If neither option is present the format used in earlier versions of OpenSSL is used. Use of the old format is \fBstrongly\fR discouraged because it only displays fields mentioned in the \fBpolicy\fR section, mishandles multicharacter string types and does not display extensions. .IP "\fBcopy_extensions\fR" 4 .IX Item "copy_extensions" Determines how extensions in certificate requests should be handled. If set to \fBnone\fR or this option is not present then extensions are ignored and not copied to the certificate. If set to \fBcopy\fR then any extensions present in the request that are not already present are copied to the certificate. If set to \fBcopyall\fR then all extensions in the request are copied to the certificate: if the extension is already present in the certificate it is deleted first. See the \fB\s-1WARNINGS\s0\fR section before using this option. .Sp The main use of this option is to allow a certificate request to supply values for certain extensions such as subjectAltName. .SH "POLICY FORMAT" .IX Header "POLICY FORMAT" The policy section consists of a set of variables corresponding to certificate \s-1DN\s0 fields. If the value is \*(L"match\*(R" then the field value must match the same field in the \s-1CA\s0 certificate. If the value is \&\*(L"supplied\*(R" then it must be present. If the value is \*(L"optional\*(R" then it may be present. Any fields not mentioned in the policy section are silently deleted, unless the \fB\-preserveDN\fR option is set but this can be regarded more of a quirk than intended behaviour. .SH "SPKAC FORMAT" .IX Header "SPKAC FORMAT" The input to the \fB\-spkac\fR command line option is a Netscape signed public key and challenge. This will usually come from the \fB\s-1KEYGEN\s0\fR tag in an \s-1HTML\s0 form to create a new private key. It is however possible to create SPKACs using the \fBspkac\fR utility. .PP The file should contain the variable \s-1SPKAC\s0 set to the value of the \s-1SPKAC\s0 and also the required \s-1DN\s0 components as name value pairs. If you need to include the same component twice then it can be preceded by a number and a '.'. .PP When processing \s-1SPKAC\s0 format, the output is \s-1DER\s0 if the \fB\-out\fR flag is used, but \s-1PEM\s0 format if sending to stdout or the \fB\-outdir\fR flag is used. .SH "EXAMPLES" .IX Header "EXAMPLES" Note: these examples assume that the \fBca\fR directory structure is already set up and the relevant files already exist. This usually involves creating a \s-1CA\s0 certificate and private key with \fBreq\fR, a serial number file and an empty index file and placing them in the relevant directories. .PP To use the sample configuration file below the directories demoCA, demoCA/private and demoCA/newcerts would be created. The \s-1CA\s0 certificate would be copied to demoCA/cacert.pem and its private key to demoCA/private/cakey.pem. A file demoCA/serial would be created containing for example \*(L"01\*(R" and the empty index file demoCA/index.txt. .PP Sign a certificate request: .PP .Vb 1 \& openssl ca \-in req.pem \-out newcert.pem .Ve .PP Sign a certificate request, using \s-1CA\s0 extensions: .PP .Vb 1 \& openssl ca \-in req.pem \-extensions v3_ca \-out newcert.pem .Ve .PP Generate a \s-1CRL\s0 .PP .Vb 1 \& openssl ca \-gencrl \-out crl.pem .Ve .PP Sign several requests: .PP .Vb 1 \& openssl ca \-infiles req1.pem req2.pem req3.pem .Ve .PP Certify a Netscape \s-1SPKAC:\s0 .PP .Vb 1 \& openssl ca \-spkac spkac.txt .Ve .PP A sample \s-1SPKAC\s0 file (the \s-1SPKAC\s0 line has been truncated for clarity): .PP .Vb 5 \& SPKAC=MIG0MGAwXDANBgkqhkiG9w0BAQEFAANLADBIAkEAn7PDhCeV/xIxUg8V70YRxK2A5 \& CN=Steve Test \& emailAddress=steve@openssl.org \& 0.OU=OpenSSL Group \& 1.OU=Another Group .Ve .PP A sample configuration file with the relevant sections for \fBca\fR: .PP .Vb 2 \& [ ca ] \& default_ca = CA_default # The default ca section \& \& [ CA_default ] \& \& dir = ./demoCA # top dir \& database = $dir/index.txt # index file. \& new_certs_dir = $dir/newcerts # new certs dir \& \& certificate = $dir/cacert.pem # The CA cert \& serial = $dir/serial # serial no file \& #rand_serial = yes # for random serial#\*(Aqs \& private_key = $dir/private/cakey.pem# CA private key \& RANDFILE = $dir/private/.rand # random number file \& \& default_days = 365 # how long to certify for \& default_crl_days= 30 # how long before next CRL \& default_md = md5 # md to use \& \& policy = policy_any # default policy \& email_in_dn = no # Don\*(Aqt add the email into cert DN \& \& name_opt = ca_default # Subject name display option \& cert_opt = ca_default # Certificate display option \& copy_extensions = none # Don\*(Aqt copy extensions from request \& \& [ policy_any ] \& countryName = supplied \& stateOrProvinceName = optional \& organizationName = optional \& organizationalUnitName = optional \& commonName = supplied \& emailAddress = optional .Ve .SH "FILES" .IX Header "FILES" Note: the location of all files can change either by compile time options, configuration file entries, environment variables or command line options. The values below reflect the default values. .PP .Vb 10 \& /usr/local/ssl/lib/openssl.cnf \- master configuration file \& ./demoCA \- main CA directory \& ./demoCA/cacert.pem \- CA certificate \& ./demoCA/private/cakey.pem \- CA private key \& ./demoCA/serial \- CA serial number file \& ./demoCA/serial.old \- CA serial number backup file \& ./demoCA/index.txt \- CA text database file \& ./demoCA/index.txt.old \- CA text database backup file \& ./demoCA/certs \- certificate output file \& ./demoCA/.rnd \- CA random seed information .Ve .SH "RESTRICTIONS" .IX Header "RESTRICTIONS" The text database index file is a critical part of the process and if corrupted it can be difficult to fix. It is theoretically possible to rebuild the index file from all the issued certificates and a current \&\s-1CRL:\s0 however there is no option to do this. .PP V2 \s-1CRL\s0 features like delta CRLs are not currently supported. .PP Although several requests can be input and handled at once it is only possible to include one \s-1SPKAC\s0 or self-signed certificate. .SH "BUGS" .IX Header "BUGS" The use of an in-memory text database can cause problems when large numbers of certificates are present because, as the name implies the database has to be kept in memory. .PP The \fBca\fR command really needs rewriting or the required functionality exposed at either a command or interface level so a more friendly utility (perl script or \s-1GUI\s0) can handle things properly. The script \&\fB\s-1CA\s0.pl\fR helps a little but not very much. .PP Any fields in a request that are not present in a policy are silently deleted. This does not happen if the \fB\-preserveDN\fR option is used. To enforce the absence of the \s-1EMAIL\s0 field within the \s-1DN,\s0 as suggested by RFCs, regardless the contents of the request' subject the \fB\-noemailDN\fR option can be used. The behaviour should be more friendly and configurable. .PP Canceling some commands by refusing to certify a certificate can create an empty file. .SH "WARNINGS" .IX Header "WARNINGS" The \fBca\fR command is quirky and at times downright unfriendly. .PP The \fBca\fR utility was originally meant as an example of how to do things in a \s-1CA.\s0 It was not supposed to be used as a full blown \s-1CA\s0 itself: nevertheless some people are using it for this purpose. .PP The \fBca\fR command is effectively a single user command: no locking is done on the various files and attempts to run more than one \fBca\fR command on the same database can have unpredictable results. .PP The \fBcopy_extensions\fR option should be used with caution. If care is not taken then it can be a security risk. For example if a certificate request contains a basicConstraints extension with \s-1CA:TRUE\s0 and the \&\fBcopy_extensions\fR value is set to \fBcopyall\fR and the user does not spot this when the certificate is displayed then this will hand the requester a valid \s-1CA\s0 certificate. .PP This situation can be avoided by setting \fBcopy_extensions\fR to \fBcopy\fR and including basicConstraints with \s-1CA:FALSE\s0 in the configuration file. Then if the request contains a basicConstraints extension it will be ignored. .PP It is advisable to also include values for other extensions such as \fBkeyUsage\fR to prevent a request supplying its own values. .PP Additional restrictions can be placed on the \s-1CA\s0 certificate itself. For example if the \s-1CA\s0 certificate has: .PP .Vb 1 \& basicConstraints = CA:TRUE, pathlen:0 .Ve .PP then even if a certificate is issued with \s-1CA:TRUE\s0 it will not be valid. .SH "HISTORY" .IX Header "HISTORY" Since OpenSSL 1.1.1, the program follows \s-1RFC5280.\s0 Specifically, certificate validity period (specified by any of \fB\-startdate\fR, \&\fB\-enddate\fR and \fB\-days\fR) will be encoded as UTCTime if the dates are earlier than year 2049 (included), and as GeneralizedTime if the dates are in year 2050 or later. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBreq\fR\|(1), \fBspkac\fR\|(1), \fBx509\fR\|(1), \s-1\fBCA\s0.pl\fR\|(1), \&\fBconfig\fR\|(5), \fBx509v3_config\fR\|(5) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2021 The OpenSSL Project Authors.

This option can be used multiple times to \*(L"drill down\*(R" into a nested structure. .IP "\fB\-genstr string\fR, \fB\-genconf file\fR" 4 .IX Item "-genstr string, -genconf file" Generate encoded data based on \fBstring\fR, \fBfile\fR or both using \&\fBASN1_generate_nconf\fR\|(3) format. If \fBfile\fR only is present then the string is obtained from the default section using the name \&\fBasn1\fR. The encoded data is passed through the \s-1ASN1\s0 parser and printed out as though it came from a file, the contents can thus be examined and written to a file using the \fBout\fR option. .IP "\fB\-strictpem\fR" 4 .IX Item "-strictpem" If this option is used then \fB\-inform\fR will be ignored. Without this option any data in a \s-1PEM\s0 format input file will be treated as being base64 encoded and processed whether it has the normal \s-1PEM BEGIN\s0 and \s-1END\s0 markers or not.

PKCS#12 files are used by several programs including Netscape, \s-1MSIE\s0 and \s-1MS\s0 Outlook. .SH "OPTIONS" .IX Header "OPTIONS" There are a lot of options the meaning of some depends of whether a PKCS#12 file is being created or parsed. By default a PKCS#12 file is parsed. A PKCS#12 file can be created by using the \fB\-export\fR option (see below). .SH "PARSING OPTIONS" .IX Header "PARSING OPTIONS" .IP "\fB\-help\fR" 4 .IX Item "-help" Print out a usage message. .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" This specifies filename of the PKCS#12 file to be parsed. Standard input is used by default. .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" The filename to write certificates and private keys to, standard output by default. They are all written in \s-1PEM\s0 format. .IP "\fB\-passin arg\fR" 4 .IX Item "-passin arg" The PKCS#12 file (i.e. input file) password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-passout arg\fR" 4 .IX Item "-passout arg" Pass phrase source to encrypt any outputted private keys with. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-password arg\fR" 4 .IX Item "-password arg" With \-export, \-password is equivalent to \-passout. Otherwise, \-password is equivalent to \-passin. .IP "\fB\-noout\fR" 4 .IX Item "-noout" This option inhibits output of the keys and certificates to the output file version of the PKCS#12 file. .IP "\fB\-clcerts\fR" 4 .IX Item "-clcerts" Only output client certificates (not \s-1CA\s0 certificates). .IP "\fB\-cacerts\fR" 4 .IX Item "-cacerts" Only output \s-1CA\s0 certificates (not client certificates). .IP "\fB\-nocerts\fR" 4 .IX Item "-nocerts" No certificates at all will be output. .IP "\fB\-nokeys\fR" 4 .IX Item "-nokeys" No private keys will be output. .IP "\fB\-info\fR" 4 .IX Item "-info" Output additional information about the PKCS#12 file structure, algorithms used and iteration counts. .IP "\fB\-des\fR" 4 .IX Item "-des" Use \s-1DES\s0 to encrypt private keys before outputting. .IP "\fB\-des3\fR" 4 .IX Item "-des3" Use triple \s-1DES\s0 to encrypt private keys before outputting, this is the default. .IP "\fB\-idea\fR" 4 .IX Item "-idea" Use \s-1IDEA\s0 to encrypt private keys before outputting. .IP "\fB\-aes128\fR, \fB\-aes192\fR, \fB\-aes256\fR" 4 .IX Item "-aes128, -aes192, -aes256" Use \s-1AES\s0 to encrypt private keys before outputting. .IP "\fB\-aria128\fR, \fB\-aria192\fR, \fB\-aria256\fR" 4 .IX Item "-aria128, -aria192, -aria256" Use \s-1ARIA\s0 to encrypt private keys before outputting. .IP "\fB\-camellia128\fR, \fB\-camellia192\fR, \fB\-camellia256\fR" 4 .IX Item "-camellia128, -camellia192, -camellia256" Use Camellia to encrypt private keys before outputting. .IP "\fB\-nodes\fR" 4 .IX Item "-nodes" Don't encrypt the private keys at all. .IP "\fB\-nomacver\fR" 4 .IX Item "-nomacver" Don't attempt to verify the integrity \s-1MAC\s0 before reading the file. .IP "\fB\-twopass\fR" 4 .IX Item "-twopass" Prompt for separate integrity and encryption passwords: most software always assumes these are the same so this option will render such PKCS#12 files unreadable. Cannot be used in combination with the options \&\-password, \-passin (if importing) or \-passout (if exporting). .SH "FILE CREATION OPTIONS" .IX Header "FILE CREATION OPTIONS" .IP "\fB\-export\fR" 4 .IX Item "-export" This option specifies that a PKCS#12 file will be created rather than parsed. .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" This specifies filename to write the PKCS#12 file to. Standard output is used by default. .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" The filename to read certificates and private keys from, standard input by default. They must all be in \s-1PEM\s0 format. The order doesn't matter but one private key and its corresponding certificate should be present. If additional certificates are present they will also be included in the PKCS#12 file. .IP "\fB\-inkey file_or_id\fR" 4 .IX Item "-inkey file_or_id" File to read private key from. If not present then a private key must be present in the input file. If no engine is used, the argument is taken as a file; if an engine is specified, the argument is given to the engine as a key identifier. .IP "\fB\-name friendlyname\fR" 4 .IX Item "-name friendlyname" This specifies the \*(L"friendly name\*(R" for the certificate and private key. This name is typically displayed in list boxes by software importing the file. .IP "\fB\-certfile filename\fR" 4 .IX Item "-certfile filename" A filename to read additional certificates from. .IP "\fB\-caname friendlyname\fR" 4 .IX Item "-caname friendlyname" This specifies the \*(L"friendly name\*(R" for other certificates. This option may be used multiple times to specify names for all certificates in the order they appear. Netscape ignores friendly names on other certificates whereas \s-1MSIE\s0 displays them. .IP "\fB\-pass arg\fR, \fB\-passout arg\fR" 4 .IX Item "-pass arg, -passout arg" The PKCS#12 file (i.e. output file) password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-passin password\fR" 4 .IX Item "-passin password" Pass phrase source to decrypt any input private keys with. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-chain\fR" 4 .IX Item "-chain" If this option is present then an attempt is made to include the entire certificate chain of the user certificate. The standard \s-1CA\s0 store is used for this search. If the search fails it is considered a fatal error. .IP "\fB\-descert\fR" 4 .IX Item "-descert" Encrypt the certificate using triple \s-1DES,\s0 this may render the PKCS#12 file unreadable by some \*(L"export grade\*(R" software. By default the private key is encrypted using triple \s-1DES\s0 and the certificate using 40 bit \s-1RC2\s0 unless \s-1RC2\s0 is disabled in which case triple \s-1DES\s0 is used. .IP "\fB\-keypbe alg\fR, \fB\-certpbe alg\fR" 4 .IX Item "-keypbe alg, -certpbe alg" These options allow the algorithm used to encrypt the private key and certificates to be selected. Any PKCS#5 v1.5 or PKCS#12 \s-1PBE\s0 algorithm name can be used (see \fB\s-1NOTES\s0\fR section for more information). If a cipher name (as output by the \fBlist-cipher-algorithms\fR command is specified then it is used with PKCS#5 v2.0. For interoperability reasons it is advisable to only use PKCS#12 algorithms. .IP "\fB\-keyex|\-keysig\fR" 4 .IX Item "-keyex|-keysig" Specifies that the private key is to be used for key exchange or just signing. This option is only interpreted by \s-1MSIE\s0 and similar \s-1MS\s0 software. Normally \&\*(L"export grade\*(R" software will only allow 512 bit \s-1RSA\s0 keys to be used for encryption purposes but arbitrary length keys for signing. The \fB\-keysig\fR option marks the key for signing only. Signing only keys can be used for S/MIME signing, authenticode (ActiveX control signing) and \s-1SSL\s0 client authentication, however, due to a bug only \s-1MSIE 5.0\s0 and later support the use of signing only keys for \s-1SSL\s0 client authentication. .IP "\fB\-macalg digest\fR" 4 .IX Item "-macalg digest" Specify the \s-1MAC\s0 digest algorithm. If not included them \s-1SHA1\s0 will be used. .IP "\fB\-nomaciter\fR, \fB\-noiter\fR" 4 .IX Item "-nomaciter, -noiter" These options affect the iteration counts on the \s-1MAC\s0 and key algorithms. Unless you wish to produce files compatible with \s-1MSIE 4.0\s0 you should leave these options alone. .Sp To discourage attacks by using large dictionaries of common passwords the algorithm that derives keys from passwords can have an iteration count applied to it: this causes a certain part of the algorithm to be repeated and slows it down. The \s-1MAC\s0 is used to check the file integrity but since it will normally have the same password as the keys and certificates it could also be attacked. By default both \s-1MAC\s0 and encryption iteration counts are set to 2048, using these options the \s-1MAC\s0 and encryption iteration counts can be set to 1, since this reduces the file security you should not use these options unless you really have to. Most software supports both \s-1MAC\s0 and key iteration counts. \&\s-1MSIE 4.0\s0 doesn't support \s-1MAC\s0 iteration counts so it needs the \fB\-nomaciter\fR option. .IP "\fB\-maciter\fR" 4 .IX Item "-maciter" This option is included for compatibility with previous versions, it used to be needed to use \s-1MAC\s0 iterations counts but they are now used by default. .IP "\fB\-nomac\fR" 4 .IX Item "-nomac" Don't attempt to provide the \s-1MAC\s0 integrity. .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fB\-CAfile file\fR" 4 .IX Item "-CAfile file" \&\s-1CA\s0 storage as a file. .IP "\fB\-CApath dir\fR" 4 .IX Item "-CApath dir" \&\s-1CA\s0 storage as a directory. This directory must be a standard certificate directory: that is a hash of each subject name (using \fBx509 \-hash\fR) should be linked to each certificate. .IP "\fB\-no\-CAfile\fR" 4 .IX Item "-no-CAfile" Do not load the trusted \s-1CA\s0 certificates from the default file location. .IP "\fB\-no\-CApath\fR" 4 .IX Item "-no-CApath" Do not load the trusted \s-1CA\s0 certificates from the default directory location. .IP "\fB\-CSP name\fR" 4 .IX Item "-CSP name" Write \fBname\fR as a Microsoft \s-1CSP\s0 name. .SH "NOTES" .IX Header "NOTES" Although there are a large number of options most of them are very rarely used. For PKCS#12 file parsing only \fB\-in\fR and \fB\-out\fR need to be used for PKCS#12 file creation \fB\-export\fR and \fB\-name\fR are also used. .PP If none of the \fB\-clcerts\fR, \fB\-cacerts\fR or \fB\-nocerts\fR options are present then all certificates will be output in the order they appear in the input PKCS#12 files. There is no guarantee that the first certificate present is the one corresponding to the private key. Certain software which requires a private key and certificate and assumes the first certificate in the file is the one corresponding to the private key: this may not always be the case. Using the \fB\-clcerts\fR option will solve this problem by only outputting the certificate corresponding to the private key. If the \s-1CA\s0 certificates are required then they can be output to a separate file using the \fB\-nokeys \-cacerts\fR options to just output \s-1CA\s0 certificates. .PP The \fB\-keypbe\fR and \fB\-certpbe\fR algorithms allow the precise encryption algorithms for private keys and certificates to be specified. Normally the defaults are fine but occasionally software can't handle triple \s-1DES\s0 encrypted private keys, then the option \fB\-keypbe \s-1PBE\-SHA1\-RC2\-40\s0\fR can be used to reduce the private key encryption to 40 bit \s-1RC2. A\s0 complete description of all algorithms is contained in the \fBpkcs8\fR manual page. .PP Prior 1.1 release passwords containing non-ASCII characters were encoded in non-compliant manner, which limited interoperability, in first hand with Windows. But switching to standard-compliant password encoding poses problem accessing old data protected with broken encoding. For this reason even legacy encodings is attempted when reading the data. If you use PKCS#12 files in production application you are advised to convert the data, because implemented heuristic approach is not MT-safe, its sole goal is to facilitate the data upgrade with this utility. .SH "EXAMPLES" .IX Header "EXAMPLES" Parse a PKCS#12 file and output it to a file: .PP .Vb 1 \& openssl pkcs12 \-in file.p12 \-out file.pem .Ve .PP Output only client certificates to a file: .PP .Vb 1 \& openssl pkcs12 \-in file.p12 \-clcerts \-out file.pem .Ve .PP Don't encrypt the private key: .PP .Vb 1 \& openssl pkcs12 \-in file.p12 \-out file.pem \-nodes .Ve .PP Print some info about a PKCS#12 file: .PP .Vb 1 \& openssl pkcs12 \-in file.p12 \-info \-noout .Ve .PP Create a PKCS#12 file: .PP .Vb 1 \& openssl pkcs12 \-export \-in file.pem \-out file.p12 \-name "My Certificate" .Ve .PP Include some extra certificates: .PP .Vb 2 \& openssl pkcs12 \-export \-in file.pem \-out file.p12 \-name "My Certificate" \e \& \-certfile othercerts.pem .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBpkcs8\fR\|(1) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2021 The OpenSSL Project Authors.

The OpenSSL operations and options are indicated below. .PP Unless otherwise mentioned all algorithms support the \fBdigest:alg\fR option which specifies the digest in use for sign, verify and verifyrecover operations. The value \fBalg\fR should represent a digest name as used in the \&\fBEVP_get_digestbyname()\fR function for example \fBsha1\fR. This value is not used to hash the input data. It is used (by some algorithms) for sanity-checking the lengths of data passed in to the \fBpkeyutl\fR and for creating the structures that make up the signature (e.g. \fBDigestInfo\fR in \s-1RSASSA\s0 PKCS#1 v1.5 signatures). .PP This utility does not hash the input data but rather it will use the data directly as input to the signature algorithm. Depending on the key type, signature type, and mode of padding, the maximum acceptable lengths of input data differ. The signed data can't be longer than the key modulus with \s-1RSA.\s0 In case of \s-1ECDSA\s0 and \s-1DSA\s0 the data shouldn't be longer than the field size, otherwise it will be silently truncated to the field size. In any event the input size must not be larger than the largest supported digest size. .PP In other words, if the value of digest is \fBsha1\fR the input should be the 20 bytes long binary encoding of the \s-1SHA\-1\s0 hash function output. .PP The Ed25519 and Ed448 signature algorithms are not supported by this utility. They accept non-hashed input, but this utility can only be used to sign hashed input. .SH "RSA ALGORITHM" .IX Header "RSA ALGORITHM" The \s-1RSA\s0 algorithm generally supports the encrypt, decrypt, sign, verify and verifyrecover operations. However, some padding modes support only a subset of these operations. The following additional \&\fBpkeyopt\fR values are supported: .IP "\fBrsa_padding_mode:mode\fR" 4 .IX Item "rsa_padding_mode:mode" This sets the \s-1RSA\s0 padding mode. Acceptable values for \fBmode\fR are \fBpkcs1\fR for PKCS#1 padding, \fBsslv23\fR for SSLv23 padding, \fBnone\fR for no padding, \fBoaep\fR for \fB\s-1OAEP\s0\fR mode, \fBx931\fR for X9.31 mode and \fBpss\fR for \s-1PSS.\s0 .Sp In PKCS#1 padding if the message digest is not set then the supplied data is signed or verified directly instead of using a \fBDigestInfo\fR structure. If a digest is set then the a \fBDigestInfo\fR structure is used and its the length must correspond to the digest type. .Sp For \fBoaep\fR mode only encryption and decryption is supported. .Sp For \fBx931\fR if the digest type is set it is used to format the block data otherwise the first byte is used to specify the X9.31 digest \s-1ID.\s0 Sign, verify and verifyrecover are can be performed in this mode. .Sp For \fBpss\fR mode only sign and verify are supported and the digest type must be specified. .IP "\fBrsa_pss_saltlen:len\fR" 4 .IX Item "rsa_pss_saltlen:len" For \fBpss\fR mode only this option specifies the salt length. Three special values are supported: \*(L"digest\*(R" sets the salt length to the digest length, \&\*(L"max\*(R" sets the salt length to the maximum permissible value. When verifying \&\*(L"auto\*(R" causes the salt length to be automatically determined based on the \&\fB\s-1PSS\s0\fR block structure. .IP "\fBrsa_mgf1_md:digest\fR" 4 .IX Item "rsa_mgf1_md:digest" For \s-1PSS\s0 and \s-1OAEP\s0 padding sets the \s-1MGF1\s0 digest. If the \s-1MGF1\s0 digest is not explicitly set in \s-1PSS\s0 mode then the signing digest is used. .IP "\fBrsa_oaep_md:\fR\fIdigest\fR" 4 .IX Item "rsa_oaep_md:digest" Sets the digest used for the \s-1OAEP\s0 hash function. If not explicitly set then \&\s-1SHA1\s0 is used. .SH "RSA-PSS ALGORITHM" .IX Header "RSA-PSS ALGORITHM" The RSA-PSS algorithm is a restricted version of the \s-1RSA\s0 algorithm which only supports the sign and verify operations with \s-1PSS\s0 padding. The following additional \fBpkeyopt\fR values are supported: .IP "\fBrsa_padding_mode:mode\fR, \fBrsa_pss_saltlen:len\fR, \fBrsa_mgf1_md:digest\fR" 4 .IX Item "rsa_padding_mode:mode, rsa_pss_saltlen:len, rsa_mgf1_md:digest" These have the same meaning as the \fB\s-1RSA\s0\fR algorithm with some additional restrictions. The padding mode can only be set to \fBpss\fR which is the default value. .Sp If the key has parameter restrictions than the digest, \s-1MGF1\s0 digest and salt length are set to the values specified in the parameters. The digest and \s-1MG\s0 cannot be changed and the salt length cannot be set to a value less than the minimum restriction. .SH "DSA ALGORITHM" .IX Header "DSA ALGORITHM" The \s-1DSA\s0 algorithm supports signing and verification operations only. Currently there are no additional \fB\-pkeyopt\fR options other than \fBdigest\fR. The \s-1SHA1\s0 digest is assumed by default. .SH "DH ALGORITHM" .IX Header "DH ALGORITHM" The \s-1DH\s0 algorithm only supports the derivation operation and no additional \&\fB\-pkeyopt\fR options. .SH "EC ALGORITHM" .IX Header "EC ALGORITHM" The \s-1EC\s0 algorithm supports sign, verify and derive operations. The sign and verify operations use \s-1ECDSA\s0 and derive uses \s-1ECDH. SHA1\s0 is assumed by default for the \fB\-pkeyopt\fR \fBdigest\fR option. .SH "X25519 and X448 ALGORITHMS" .IX Header "X25519 and X448 ALGORITHMS" The X25519 and X448 algorithms support key derivation only. Currently there are no additional options. .SH "EXAMPLES" .IX Header "EXAMPLES" Sign some data using a private key: .PP .Vb 1 \& openssl pkeyutl \-sign \-in file \-inkey key.pem \-out sig .Ve .PP Recover the signed data (e.g. if an \s-1RSA\s0 key is used): .PP .Vb 1 \& openssl pkeyutl \-verifyrecover \-in sig \-inkey key.pem .Ve .PP Verify the signature (e.g. a \s-1DSA\s0 key): .PP .Vb 1 \& openssl pkeyutl \-verify \-in file \-sigfile sig \-inkey key.pem .Ve .PP Sign data using a message digest value (this is currently only valid for \s-1RSA\s0): .PP .Vb 1 \& openssl pkeyutl \-sign \-in file \-inkey key.pem \-out sig \-pkeyopt digest:sha256 .Ve .PP Derive a shared secret value: .PP .Vb 1 \& openssl pkeyutl \-derive \-inkey key.pem \-peerkey pubkey.pem \-out secret .Ve .PP Hexdump 48 bytes of \s-1TLS1 PRF\s0 using digest \fB\s-1SHA256\s0\fR and shared secret and seed consisting of the single byte 0xFF: .PP .Vb 2 \& openssl pkeyutl \-kdf TLS1\-PRF \-kdflen 48 \-pkeyopt md:SHA256 \e \& \-pkeyopt hexsecret:ff \-pkeyopt hexseed:ff \-hexdump .Ve .PP Decrypt some data using a private key with \s-1OAEP\s0 padding using \s-1SHA256:\s0 .PP .Vb 2 \& openssl pkeyutl \-decrypt \-in file \-inkey key.pem \-out secret \e \& \-pkeyopt rsa_padding_mode:oaep \-pkeyopt rsa_oaep_md:sha256 .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBgenpkey\fR\|(1), \fBpkey\fR\|(1), \fBrsautl\fR\|(1) \&\fBdgst\fR\|(1), \fBrsa\fR\|(1), \fBgenrsa\fR\|(1), \&\fBEVP_PKEY_CTX_set_hkdf_md\fR\|(3), \fBEVP_PKEY_CTX_set_tls1_prf_md\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2006\-2021 The OpenSSL Project Authors.

They can be converted between various forms and their components printed out. \fBNote\fR OpenSSL uses the private key format specified in '\s-1SEC 1:\s0 Elliptic Curve Cryptography' (http://www.secg.org/). To convert an OpenSSL \s-1EC\s0 private key into the PKCS#8 private key format use the \fBpkcs8\fR command. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-help\fR" 4 .IX Item "-help" Print out a usage message. .IP "\fB\-inform DER|PEM\fR" 4 .IX Item "-inform DER|PEM" This specifies the input format. The \fB\s-1DER\s0\fR option with a private key uses an \s-1ASN.1 DER\s0 encoded \s-1SEC1\s0 private key. When used with a public key it uses the SubjectPublicKeyInfo structure as specified in \s-1RFC 3280.\s0 The \fB\s-1PEM\s0\fR form is the default format: it consists of the \fB\s-1DER\s0\fR format base64 encoded with additional header and footer lines. In the case of a private key PKCS#8 format is also accepted. .IP "\fB\-outform DER|PEM\fR" 4 .IX Item "-outform DER|PEM" This specifies the output format, the options have the same meaning and default as the \fB\-inform\fR option. .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" This specifies the input filename to read a key from or standard input if this option is not specified. If the key is encrypted a pass phrase will be prompted for. .IP "\fB\-passin arg\fR" 4 .IX Item "-passin arg" The input file password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" This specifies the output filename to write a key to or standard output by is not specified. If any encryption options are set then a pass phrase will be prompted for. The output filename should \fBnot\fR be the same as the input filename. .IP "\fB\-passout arg\fR" 4 .IX Item "-passout arg" The output file password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-des|\-des3|\-idea\fR" 4 .IX Item "-des|-des3|-idea" These options encrypt the private key with the \s-1DES,\s0 triple \s-1DES, IDEA\s0 or any other cipher supported by OpenSSL before outputting it. A pass phrase is prompted for. If none of these options is specified the key is written in plain text. This means that using the \fBec\fR utility to read in an encrypted key with no encryption option can be used to remove the pass phrase from a key, or by setting the encryption options it can be use to add or change the pass phrase. These options can only be used with \s-1PEM\s0 format output files. .IP "\fB\-text\fR" 4 .IX Item "-text" Prints out the public, private key components and parameters. .IP "\fB\-noout\fR" 4 .IX Item "-noout" This option prevents output of the encoded version of the key. .IP "\fB\-pubin\fR" 4 .IX Item "-pubin" By default, a private key is read from the input file. With this option a public key is read instead. .IP "\fB\-pubout\fR" 4 .IX Item "-pubout" By default a private key is output. With this option a public key will be output instead. This option is automatically set if the input is a public key. .IP "\fB\-conv_form\fR" 4 .IX Item "-conv_form" This specifies how the points on the elliptic curve are converted into octet strings. Possible values are: \fBcompressed\fR (the default value), \fBuncompressed\fR and \fBhybrid\fR. For more information regarding the point conversion forms please read the X9.62 standard. \&\fBNote\fR Due to patent issues the \fBcompressed\fR option is disabled by default for binary curves and can be enabled by defining the preprocessor macro \fB\s-1OPENSSL_EC_BIN_PT_COMP\s0\fR at compile time. .IP "\fB\-param_enc arg\fR" 4 .IX Item "-param_enc arg" This specifies how the elliptic curve parameters are encoded. Possible value are: \fBnamed_curve\fR, i.e. the ec parameters are specified by an \s-1OID,\s0 or \fBexplicit\fR where the ec parameters are explicitly given (see \s-1RFC 3279\s0 for the definition of the \&\s-1EC\s0 parameters structures). The default value is \fBnamed_curve\fR. \&\fBNote\fR the \fBimplicitlyCA\fR alternative, as specified in \s-1RFC 3279,\s0 is currently not implemented in OpenSSL. .IP "\fB\-no_public\fR" 4 .IX Item "-no_public" This option omits the public key components from the private key output. .IP "\fB\-check\fR" 4 .IX Item "-check" This option checks the consistency of an \s-1EC\s0 private or public key. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBec\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. .SH "NOTES" .IX Header "NOTES" The \s-1PEM\s0 private key format uses the header and footer lines: .PP .Vb 2 \& \-\-\-\-\-BEGIN EC PRIVATE KEY\-\-\-\-\- \& \-\-\-\-\-END EC PRIVATE KEY\-\-\-\-\- .Ve .PP The \s-1PEM\s0 public key format uses the header and footer lines: .PP .Vb 2 \& \-\-\-\-\-BEGIN PUBLIC KEY\-\-\-\-\- \& \-\-\-\-\-END PUBLIC KEY\-\-\-\-\- .Ve .SH "EXAMPLES" .IX Header "EXAMPLES" To encrypt a private key using triple \s-1DES:\s0 .PP .Vb 1 \& openssl ec \-in key.pem \-des3 \-out keyout.pem .Ve .PP To convert a private key from \s-1PEM\s0 to \s-1DER\s0 format: .PP .Vb 1 \& openssl ec \-in key.pem \-outform DER \-out keyout.der .Ve .PP To print out the components of a private key to standard output: .PP .Vb 1 \& openssl ec \-in key.pem \-text \-noout .Ve .PP To just output the public part of a private key: .PP .Vb 1 \& openssl ec \-in key.pem \-pubout \-out pubkey.pem .Ve .PP To change the parameters encoding to \fBexplicit\fR: .PP .Vb 1 \& openssl ec \-in key.pem \-param_enc explicit \-out keyout.pem .Ve .PP To change the point conversion form to \fBcompressed\fR: .PP .Vb 1 \& openssl ec \-in key.pem \-conv_form compressed \-out keyout.pem .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBecparam\fR\|(1), \fBdsa\fR\|(1), \fBrsa\fR\|(1) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2003\-2021 The OpenSSL Project Authors.

It can be used for .PP .Vb 8 \& o Creation and management of private keys, public keys and parameters \& o Public key cryptographic operations \& o Creation of X.509 certificates, CSRs and CRLs \& o Calculation of Message Digests \& o Encryption and Decryption with Ciphers \& o SSL/TLS Client and Server Tests \& o Handling of S/MIME signed or encrypted mail \& o Time Stamp requests, generation and verification .Ve .SH "COMMAND SUMMARY" .IX Header "COMMAND SUMMARY" The \fBopenssl\fR program provides a rich variety of commands (\fIcommand\fR in the \&\s-1SYNOPSIS\s0 above), each of which often has a wealth of options and arguments (\fIcommand_opts\fR and \fIcommand_args\fR in the \s-1SYNOPSIS\s0). .PP Detailed documentation and use cases for most standard subcommands are available (e.g., \fBx509\fR\|(1) or \fBopenssl\-x509\fR\|(1)). .PP Many commands use an external configuration file for some or all of their arguments and have a \fB\-config\fR option to specify that file. The environment variable \fB\s-1OPENSSL_CONF\s0\fR can be used to specify the location of the file. If the environment variable is not specified, then the file is named \&\fBopenssl.cnf\fR in the default certificate storage area, whose value depends on the configuration flags specified when the OpenSSL was built. .PP The list parameters \fBstandard-commands\fR, \fBdigest-commands\fR, and \fBcipher-commands\fR output a list (one entry per line) of the names of all standard commands, message digest commands, or cipher commands, respectively, that are available in the present \fBopenssl\fR utility. .PP The list parameters \fBcipher-algorithms\fR and \&\fBdigest-algorithms\fR list all cipher and message digest names, one entry per line. Aliases are listed as: .PP .Vb 1 \& from => to .Ve .PP The list parameter \fBpublic-key-algorithms\fR lists all supported public key algorithms. .PP The command \fBno\-\fR\fI\s-1XXX\s0\fR tests whether a command of the specified name is available. If no command named \fI\s-1XXX\s0\fR exists, it returns 0 (success) and prints \fBno\-\fR\fI\s-1XXX\s0\fR; otherwise it returns 1 and prints \fI\s-1XXX\s0\fR. In both cases, the output goes to \fBstdout\fR and nothing is printed to \fBstderr\fR. Additional command line arguments are always ignored. Since for each cipher there is a command of the same name, this provides an easy way for shell scripts to test for the availability of ciphers in the \fBopenssl\fR program.

The actual fields prompted for and their maximum and minimum sizes are specified in the configuration file and any requested extensions. .Sp If the \fB\-key\fR option is not used it will generate a new \s-1RSA\s0 private key using information specified in the configuration file. .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fB\-newkey arg\fR" 4 .IX Item "-newkey arg" This option creates a new certificate request and a new private key. The argument takes one of several forms. \fBrsa:nbits\fR, where \&\fBnbits\fR is the number of bits, generates an \s-1RSA\s0 key \fBnbits\fR in size. If \fBnbits\fR is omitted, i.e. \fB\-newkey rsa\fR specified, the default key size, specified in the configuration file is used. .Sp All other algorithms support the \fB\-newkey alg:file\fR form, where file may be an algorithm parameter file, created by the \fBgenpkey \-genparam\fR command or and X.509 certificate for a key with appropriate algorithm. .Sp \&\fBparam:file\fR generates a key using the parameter file or certificate \fBfile\fR, the algorithm is determined by the parameters. \fBalgname:file\fR use algorithm \&\fBalgname\fR and parameter file \fBfile\fR: the two algorithms must match or an error occurs. \fBalgname\fR just uses algorithm \fBalgname\fR, and parameters, if necessary should be specified via \fB\-pkeyopt\fR parameter. .Sp \&\fBdsa:filename\fR generates a \s-1DSA\s0 key using the parameters in the file \fBfilename\fR. \fBec:filename\fR generates \s-1EC\s0 key (usable both with \&\s-1ECDSA\s0 or \s-1ECDH\s0 algorithms), \fBgost2001:filename\fR generates \s-1GOST R 34.10\-2001\s0 key (requires \fBccgost\fR engine configured in the configuration file). If just \fBgost2001\fR is specified a parameter set should be specified by \fB\-pkeyopt paramset:X\fR .IP "\fB\-pkeyopt opt:value\fR" 4 .IX Item "-pkeyopt opt:value" Set the public key algorithm option \fBopt\fR to \fBvalue\fR. The precise set of options supported depends on the public key algorithm used and its implementation. See \fB\s-1KEY GENERATION OPTIONS\s0\fR in the \fBgenpkey\fR manual page for more details. .IP "\fB\-key filename\fR" 4 .IX Item "-key filename" This specifies the file to read the private key from. It also accepts PKCS#8 format private keys for \s-1PEM\s0 format files. .IP "\fB\-keyform PEM|DER\fR" 4 .IX Item "-keyform PEM|DER" The format of the private key file specified in the \fB\-key\fR argument. \s-1PEM\s0 is the default. .IP "\fB\-keyout filename\fR" 4 .IX Item "-keyout filename" This gives the filename to write the newly created private key to. If this option is not specified then the filename present in the configuration file is used. .IP "\fB\-nodes\fR" 4 .IX Item "-nodes" If this option is specified then if a private key is created it will not be encrypted. .IP "\fB\-\f(BIdigest\fB\fR" 4 .IX Item "-digest" This specifies the message digest to sign the request. Any digest supported by the OpenSSL \fBdgst\fR command can be used. This overrides the digest algorithm specified in the configuration file. .Sp Some public key algorithms may override this choice. For instance, \s-1DSA\s0 signatures always use \s-1SHA1, GOST R 34.10\s0 signatures always use \&\s-1GOST R 34.11\-94\s0 (\fB\-md_gost94\fR), Ed25519 and Ed448 never use any digest. .IP "\fB\-config filename\fR" 4 .IX Item "-config filename" This allows an alternative configuration file to be specified. Optional; for a description of the default value, see \*(L"\s-1COMMAND SUMMARY\*(R"\s0 in \fBopenssl\fR\|(1). .IP "\fB\-subj arg\fR" 4 .IX Item "-subj arg" Sets subject name for new request or supersedes the subject name when processing a request. The arg must be formatted as \fI/type0=value0/type1=value1/type2=...\fR. Keyword characters may be escaped by \e (backslash), and whitespace is retained. Empty values are permitted, but the corresponding type will not be included in the request. .IP "\fB\-multivalue\-rdn\fR" 4 .IX Item "-multivalue-rdn" This option causes the \-subj argument to be interpreted with full support for multivalued RDNs. Example: .Sp \&\fI/DC=org/DC=OpenSSL/DC=users/UID=123456+CN=John Doe\fR .Sp If \-multi\-rdn is not used then the \s-1UID\s0 value is \fI123456+CN=John Doe\fR. .IP "\fB\-x509\fR" 4 .IX Item "-x509" This option outputs a self signed certificate instead of a certificate request. This is typically used to generate a test certificate or a self signed root \s-1CA.\s0 The extensions added to the certificate (if any) are specified in the configuration file. Unless specified using the \fBset_serial\fR option, a large random number will be used for the serial number. .Sp If existing request is specified with the \fB\-in\fR option, it is converted to the self signed certificate otherwise new request is created. .IP "\fB\-days n\fR" 4 .IX Item "-days n" When the \fB\-x509\fR option is being used this specifies the number of days to certify the certificate for, otherwise it is ignored. \fBn\fR should be a positive integer. The default is 30 days. .IP "\fB\-set_serial n\fR" 4 .IX Item "-set_serial n" Serial number to use when outputting a self signed certificate. This may be specified as a decimal value or a hex value if preceded by \fB0x\fR. .IP "\fB\-addext ext\fR" 4 .IX Item "-addext ext" Add a specific extension to the certificate (if the \fB\-x509\fR option is present) or certificate request. The argument must have the form of a key=value pair as it would appear in a config file. .Sp This option can be given multiple times. .IP "\fB\-extensions section\fR" 4 .IX Item "-extensions section" .PD 0 .IP "\fB\-reqexts section\fR" 4 .IX Item "-reqexts section" .PD These options specify alternative sections to include certificate extensions (if the \fB\-x509\fR option is present) or certificate request extensions. This allows several different sections to be used in the same configuration file to specify requests for a variety of purposes. .IP "\fB\-precert\fR" 4 .IX Item "-precert" A poison extension will be added to the certificate, making it a \&\*(L"pre-certificate\*(R" (see \s-1RFC6962\s0). This can be submitted to Certificate Transparency logs in order to obtain signed certificate timestamps (SCTs). These SCTs can then be embedded into the pre-certificate as an extension, before removing the poison and signing the certificate. .Sp This implies the \fB\-new\fR flag. .IP "\fB\-utf8\fR" 4 .IX Item "-utf8" This option causes field values to be interpreted as \s-1UTF8\s0 strings, by default they are interpreted as \s-1ASCII.\s0 This means that the field values, whether prompted from a terminal or obtained from a configuration file, must be valid \s-1UTF8\s0 strings. .IP "\fB\-nameopt option\fR" 4 .IX Item "-nameopt option" Option which determines how the subject or issuer names are displayed. The \&\fBoption\fR argument can be a single option or multiple options separated by commas. Alternatively the \fB\-nameopt\fR switch may be used more than once to set multiple options. See the \fBx509\fR\|(1) manual page for details. .IP "\fB\-reqopt\fR" 4 .IX Item "-reqopt" Customise the output format used with \fB\-text\fR. The \fBoption\fR argument can be a single option or multiple options separated by commas. .Sp See discussion of the \fB\-certopt\fR parameter in the \fBx509\fR\|(1) command. .IP "\fB\-newhdr\fR" 4 .IX Item "-newhdr" Adds the word \fB\s-1NEW\s0\fR to the \s-1PEM\s0 file header and footer lines on the outputted request. Some software (Netscape certificate server) and some CAs need this. .IP "\fB\-batch\fR" 4 .IX Item "-batch" Non-interactive mode. .IP "\fB\-verbose\fR" 4 .IX Item "-verbose" Print extra details about the operations being performed. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBreq\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. .IP "\fB\-keygen_engine id\fR" 4 .IX Item "-keygen_engine id" Specifies an engine (by its unique \fBid\fR string) which would be used for key generation operations. .SH "CONFIGURATION FILE FORMAT" .IX Header "CONFIGURATION FILE FORMAT" The configuration options are specified in the \fBreq\fR section of the configuration file. As with all configuration files if no value is specified in the specific section (i.e. \fBreq\fR) then the initial unnamed or \fBdefault\fR section is searched too. .PP The options available are described in detail below. .IP "\fBinput_password output_password\fR" 4 .IX Item "input_password output_password" The passwords for the input private key file (if present) and the output private key file (if one will be created). The command line options \fBpassin\fR and \fBpassout\fR override the configuration file values. .IP "\fBdefault_bits\fR" 4 .IX Item "default_bits" Specifies the default key size in bits. .Sp This option is used in conjunction with the \fB\-new\fR option to generate a new key. It can be overridden by specifying an explicit key size in the \fB\-newkey\fR option. The smallest accepted key size is 512 bits. If no key size is specified then 2048 bits is used. .IP "\fBdefault_keyfile\fR" 4 .IX Item "default_keyfile" This is the default filename to write a private key to. If not specified the key is written to standard output. This can be overridden by the \fB\-keyout\fR option. .IP "\fBoid_file\fR" 4 .IX Item "oid_file" This specifies a file containing additional \fB\s-1OBJECT IDENTIFIERS\s0\fR. Each line of the file should consist of the numerical form of the object identifier followed by white space then the short name followed by white space and finally the long name. .IP "\fBoid_section\fR" 4 .IX Item "oid_section" This specifies a section in the configuration file containing extra object identifiers. Each line should consist of the short name of the object identifier followed by \fB=\fR and the numerical form. The short and long names are the same when this option is used. .IP "\fB\s-1RANDFILE\s0\fR" 4 .IX Item "RANDFILE" At startup the specified file is loaded into the random number generator, and at exit 256 bytes will be written to it. It is used for private key generation. .IP "\fBencrypt_key\fR" 4 .IX Item "encrypt_key" If this is set to \fBno\fR then if a private key is generated it is \&\fBnot\fR encrypted. This is equivalent to the \fB\-nodes\fR command line option. For compatibility \fBencrypt_rsa_key\fR is an equivalent option. .IP "\fBdefault_md\fR" 4 .IX Item "default_md" This option specifies the digest algorithm to use. Any digest supported by the OpenSSL \fBdgst\fR command can be used. This option can be overridden on the command line. Certain signing algorithms (i.e. Ed25519 and Ed448) will ignore any digest that has been set. .IP "\fBstring_mask\fR" 4 .IX Item "string_mask" This option masks out the use of certain string types in certain fields. Most users will not need to change this option. .Sp It can be set to several values \fBdefault\fR which is also the default option uses PrintableStrings, T61Strings and BMPStrings if the \&\fBpkix\fR value is used then only PrintableStrings and BMPStrings will be used. This follows the \s-1PKIX\s0 recommendation in \s-1RFC2459.\s0 If the \&\fButf8only\fR option is used then only UTF8Strings will be used: this is the \s-1PKIX\s0 recommendation in \s-1RFC2459\s0 after 2003. Finally the \fBnombstr\fR option just uses PrintableStrings and T61Strings: certain software has problems with BMPStrings and UTF8Strings: in particular Netscape. .IP "\fBreq_extensions\fR" 4 .IX Item "req_extensions" This specifies the configuration file section containing a list of extensions to add to the certificate request. It can be overridden by the \fB\-reqexts\fR command line switch. See the \&\fBx509v3_config\fR\|(5) manual page for details of the extension section format. .IP "\fBx509_extensions\fR" 4 .IX Item "x509_extensions" This specifies the configuration file section containing a list of extensions to add to certificate generated when the \fB\-x509\fR switch is used. It can be overridden by the \fB\-extensions\fR command line switch. .IP "\fBprompt\fR" 4 .IX Item "prompt" If set to the value \fBno\fR this disables prompting of certificate fields and just takes values from the config file directly. It also changes the expected format of the \fBdistinguished_name\fR and \fBattributes\fR sections. .IP "\fButf8\fR" 4 .IX Item "utf8" If set to the value \fByes\fR then field values to be interpreted as \s-1UTF8\s0 strings, by default they are interpreted as \s-1ASCII.\s0 This means that the field values, whether prompted from a terminal or obtained from a configuration file, must be valid \s-1UTF8\s0 strings. .IP "\fBattributes\fR" 4 .IX Item "attributes" This specifies the section containing any request attributes: its format is the same as \fBdistinguished_name\fR. Typically these may contain the challengePassword or unstructuredName types. They are currently ignored by OpenSSL's request signing utilities but some CAs might want them. .IP "\fBdistinguished_name\fR" 4 .IX Item "distinguished_name" This specifies the section containing the distinguished name fields to prompt for when generating a certificate or certificate request. The format is described in the next section. .SH "DISTINGUISHED NAME AND ATTRIBUTE SECTION FORMAT" .IX Header "DISTINGUISHED NAME AND ATTRIBUTE SECTION FORMAT" There are two separate formats for the distinguished name and attribute sections. If the \fBprompt\fR option is set to \fBno\fR then these sections just consist of field names and values: for example, .PP .Vb 3 \& CN=My Name \& OU=My Organization \& emailAddress=someone@somewhere.org .Ve .PP This allows external programs (e.g. \s-1GUI\s0 based) to generate a template file with all the field names and values and just pass it to \fBreq\fR. An example of this kind of configuration file is contained in the \fB\s-1EXAMPLES\s0\fR section. .PP Alternatively if the \fBprompt\fR option is absent or not set to \fBno\fR then the file contains field prompting information. It consists of lines of the form: .PP .Vb 4 \& fieldName="prompt" \& fieldName_default="default field value" \& fieldName_min= 2 \& fieldName_max= 4 .Ve .PP \&\*(L"fieldName\*(R" is the field name being used, for example commonName (or \s-1CN\s0). The \*(L"prompt\*(R" string is used to ask the user to enter the relevant details. If the user enters nothing then the default value is used if no default value is present then the field is omitted. A field can still be omitted if a default value is present if the user just enters the '.' character. .PP The number of characters entered must be between the fieldName_min and fieldName_max limits: there may be additional restrictions based on the field being used (for example countryName can only ever be two characters long and must fit in a PrintableString). .PP Some fields (such as organizationName) can be used more than once in a \s-1DN.\s0 This presents a problem because configuration files will not recognize the same name occurring twice. To avoid this problem if the fieldName contains some characters followed by a full stop they will be ignored. So for example a second organizationName can be input by calling it \*(L"1.organizationName\*(R". .PP The actual permitted field names are any object identifier short or long names. These are compiled into OpenSSL and include the usual values such as commonName, countryName, localityName, organizationName, organizationalUnitName, stateOrProvinceName. Additionally emailAddress is included as well as name, surname, givenName, initials, and dnQualifier. .PP Additional object identifiers can be defined with the \fBoid_file\fR or \&\fBoid_section\fR options in the configuration file. Any additional fields will be treated as though they were a DirectoryString. .SH "EXAMPLES" .IX Header "EXAMPLES" Examine and verify certificate request: .PP .Vb 1 \& openssl req \-in req.pem \-text \-verify \-noout .Ve .PP Create a private key and then generate a certificate request from it: .PP .Vb 2 \& openssl genrsa \-out key.pem 2048 \& openssl req \-new \-key key.pem \-out req.pem .Ve .PP The same but just using req: .PP .Vb 1 \& openssl req \-newkey rsa:2048 \-keyout key.pem \-out req.pem .Ve .PP Generate a self signed root certificate: .PP .Vb 1 \& openssl req \-x509 \-newkey rsa:2048 \-keyout key.pem \-out req.pem .Ve .PP Example of a file pointed to by the \fBoid_file\fR option: .PP .Vb 2 \& 1.2.3.4 shortName A longer Name \& 1.2.3.6 otherName Other longer Name .Ve .PP Example of a section pointed to by \fBoid_section\fR making use of variable expansion: .PP .Vb 2 \& testoid1=1.2.3.5 \& testoid2=${testoid1}.6 .Ve .PP Sample configuration file prompting for field values: .PP .Vb 6 \& [ req ] \& default_bits = 2048 \& default_keyfile = privkey.pem \& distinguished_name = req_distinguished_name \& attributes = req_attributes \& req_extensions = v3_ca \& \& dirstring_type = nobmp \& \& [ req_distinguished_name ] \& countryName = Country Name (2 letter code) \& countryName_default = AU \& countryName_min = 2 \& countryName_max = 2 \& \& localityName = Locality Name (eg, city) \& \& organizationalUnitName = Organizational Unit Name (eg, section) \& \& commonName = Common Name (eg, YOUR name) \& commonName_max = 64 \& \& emailAddress = Email Address \& emailAddress_max = 40 \& \& [ req_attributes ] \& challengePassword = A challenge password \& challengePassword_min = 4 \& challengePassword_max = 20 \& \& [ v3_ca ] \& \& subjectKeyIdentifier=hash \& authorityKeyIdentifier=keyid:always,issuer:always \& basicConstraints = critical, CA:true .Ve .PP Sample configuration containing all field values: .PP .Vb 1 \& RANDFILE = $ENV::HOME/.rnd \& \& [ req ] \& default_bits = 2048 \& default_keyfile = keyfile.pem \& distinguished_name = req_distinguished_name \& attributes = req_attributes \& prompt = no \& output_password = mypass \& \& [ req_distinguished_name ] \& C = GB \& ST = Test State or Province \& L = Test Locality \& O = Organization Name \& OU = Organizational Unit Name \& CN = Common Name \& emailAddress = test@email.address \& \& [ req_attributes ] \& challengePassword = A challenge password .Ve .PP Example of giving the most common attributes (subject and extensions) on the command line: .PP .Vb 4 \& openssl req \-new \-subj "/C=GB/CN=foo" \e \& \-addext "subjectAltName = DNS:foo.co.uk" \e \& \-addext "certificatePolicies = 1.2.3.4" \e \& \-newkey rsa:2048 \-keyout key.pem \-out req.pem .Ve .SH "NOTES" .IX Header "NOTES" The header and footer lines in the \fB\s-1PEM\s0\fR format are normally: .PP .Vb 2 \& \-\-\-\-\-BEGIN CERTIFICATE REQUEST\-\-\-\-\- \& \-\-\-\-\-END CERTIFICATE REQUEST\-\-\-\-\- .Ve .PP some software (some versions of Netscape certificate server) instead needs: .PP .Vb 2 \& \-\-\-\-\-BEGIN NEW CERTIFICATE REQUEST\-\-\-\-\- \& \-\-\-\-\-END NEW CERTIFICATE REQUEST\-\-\-\-\- .Ve .PP which is produced with the \fB\-newhdr\fR option but is otherwise compatible. Either form is accepted transparently on input. .PP The certificate requests generated by \fBXenroll\fR with \s-1MSIE\s0 have extensions added. It includes the \fBkeyUsage\fR extension which determines the type of key (signature only or general purpose) and any additional OIDs entered by the script in an extendedKeyUsage extension. .SH "DIAGNOSTICS" .IX Header "DIAGNOSTICS" The following messages are frequently asked about: .PP .Vb 2 \& Using configuration from /some/path/openssl.cnf \& Unable to load config info .Ve .PP This is followed some time later by... .PP .Vb 2 \& unable to find \*(Aqdistinguished_name\*(Aq in config \& problems making Certificate Request .Ve .PP The first error message is the clue: it can't find the configuration file! Certain operations (like examining a certificate request) don't need a configuration file so its use isn't enforced. Generation of certificates or requests however does need a configuration file. This could be regarded as a bug. .PP Another puzzling message is this: .PP .Vb 2 \& Attributes: \& a0:00 .Ve .PP this is displayed when no attributes are present and the request includes the correct empty \fB\s-1SET OF\s0\fR structure (the \s-1DER\s0 encoding of which is 0xa0 0x00). If you just see: .PP .Vb 1 \& Attributes: .Ve .PP then the \fB\s-1SET OF\s0\fR is missing and the encoding is technically invalid (but it is tolerated). See the description of the command line option \fB\-asn1\-kludge\fR for more information. .SH "BUGS" .IX Header "BUGS" OpenSSL's handling of T61Strings (aka TeletexStrings) is broken: it effectively treats them as \s-1ISO\-8859\-1\s0 (Latin 1), Netscape and \s-1MSIE\s0 have similar behaviour. This can cause problems if you need characters that aren't available in PrintableStrings and you don't want to or can't use BMPStrings. .PP As a consequence of the T61String handling the only correct way to represent accented characters in OpenSSL is to use a BMPString: unfortunately Netscape currently chokes on these. If you have to use accented characters with Netscape and \s-1MSIE\s0 then you currently need to use the invalid T61String form. .PP The current prompting is not very friendly. It doesn't allow you to confirm what you've just entered. Other things like extensions in certificate requests are statically defined in the configuration file. Some of these: like an email address in subjectAltName should be input by the user. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBx509\fR\|(1), \fBca\fR\|(1), \fBgenrsa\fR\|(1), \&\fBgendsa\fR\|(1), \fBconfig\fR\|(5), \&\fBx509v3_config\fR\|(5) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2021 The OpenSSL Project Authors.

Some older implementations may not support PKCS#5 v2.0 and may require this option. If not specified PKCS#5 v2.0 form is used. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBpkcs8\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed.

These are detailed below. .PP If a key is being converted from PKCS#8 form (i.e. the \fB\-topk8\fR option is not used) then the input file must be in PKCS#8 format. An encrypted key is expected unless \fB\-nocrypt\fR is included. .PP If \fB\-topk8\fR is not used and \fB\s-1PEM\s0\fR mode is set the output file will be an unencrypted private key in PKCS#8 format. If the \fB\-traditional\fR option is used then a traditional format private key is written instead. .PP If \fB\-topk8\fR is not used and \fB\s-1DER\s0\fR mode is set the output file will be an unencrypted private key in traditional \s-1DER\s0 format. .PP If \fB\-topk8\fR is used then any supported private key can be used for the input file in a format specified by \fB\-inform\fR. The output file will be encrypted PKCS#8 format using the specified encryption parameters unless \fB\-nocrypt\fR is included. .SH "NOTES" .IX Header "NOTES" By default, when converting a key to PKCS#8 format, PKCS#5 v2.0 using 256 bit \&\s-1AES\s0 with \s-1HMAC\s0 and \s-1SHA256\s0 is used. .PP Some older implementations do not support PKCS#5 v2.0 format and require the older PKCS#5 v1.5 form instead, possibly also requiring insecure weak encryption algorithms such as 56 bit \s-1DES.\s0 .PP The encrypted form of a \s-1PEM\s0 encode PKCS#8 files uses the following headers and footers: .PP .Vb 2 \& \-\-\-\-\-BEGIN ENCRYPTED PRIVATE KEY\-\-\-\-\- \& \-\-\-\-\-END ENCRYPTED PRIVATE KEY\-\-\-\-\- .Ve .PP The unencrypted form uses: .PP .Vb 2 \& \-\-\-\-\-BEGIN PRIVATE KEY\-\-\-\-\- \& \-\-\-\-\-END PRIVATE KEY\-\-\-\-\- .Ve .PP Private keys encrypted using PKCS#5 v2.0 algorithms and high iteration counts are more secure that those encrypted using the traditional SSLeay compatible formats. So if additional security is considered important the keys should be converted. .PP It is possible to write out \s-1DER\s0 encoded encrypted private keys in PKCS#8 format because the encryption details are included at an \s-1ASN1\s0 level whereas the traditional format includes them at a \s-1PEM\s0 level. .SH "PKCS#5 v1.5 and PKCS#12 algorithms." .IX Header "PKCS#5 v1.5 and PKCS#12 algorithms."

The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fInumbits\fR" 4 .IX Item "numbits" This option specifies that a parameter set should be generated of size \&\fInumbits\fR. It must be the last option. If this option is present then the input file is ignored and parameters are generated instead. If this option is not present but a generator (\fB\-2\fR or \fB\-5\fR) is present, parameters are generated with a default length of 2048 bits. .IP "\fB\-noout\fR" 4 .IX Item "-noout" This option inhibits the output of the encoded version of the parameters. .IP "\fB\-text\fR" 4 .IX Item "-text" This option prints out the \s-1DH\s0 parameters in human readable form. .IP "\fB\-C\fR" 4 .IX Item "-C" This option converts the parameters into C code. The parameters can then be loaded by calling the \fBget_dhNNNN()\fR function. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBdhparam\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. .SH "WARNINGS" .IX Header "WARNINGS" The program \fBdhparam\fR combines the functionality of the programs \fBdh\fR and \&\fBgendh\fR in previous versions of OpenSSL.

It can be given any string value. If this option is not present a default value will be used. .IP "\fB\-verify int\fR, \fB\-Verify int\fR" 4 .IX Item "-verify int, -Verify int" The verify depth to use. This specifies the maximum length of the client certificate chain and makes the server request a certificate from the client. With the \fB\-verify\fR option a certificate is requested but the client does not have to send one, with the \fB\-Verify\fR option the client must supply a certificate or an error occurs. .Sp If the cipher suite cannot request a client certificate (for example an anonymous cipher suite or \s-1PSK\s0) this option has no effect. .IP "\fB\-cert infile\fR" 4 .IX Item "-cert infile" The certificate to use, most servers cipher suites require the use of a certificate and some require a certificate with a certain public key type: for example the \s-1DSS\s0 cipher suites require a certificate containing a \s-1DSS\s0 (\s-1DSA\s0) key. If not specified then the filename \*(L"server.pem\*(R" will be used. .IP "\fB\-cert_chain\fR" 4 .IX Item "-cert_chain" A file containing trusted certificates to use when attempting to build the client/server certificate chain related to the certificate specified via the \&\fB\-cert\fR option. .IP "\fB\-build_chain\fR" 4 .IX Item "-build_chain" Specify whether the application should build the certificate chain to be provided to the client. .IP "\fB\-nameopt val\fR" 4 .IX Item "-nameopt val" Option which determines how the subject or issuer names are displayed. The \&\fBval\fR argument can be a single option or multiple options separated by commas. Alternatively the \fB\-nameopt\fR switch may be used more than once to set multiple options. See the \fBx509\fR\|(1) manual page for details. .IP "\fB\-naccept +int\fR" 4 .IX Item "-naccept +int" The server will exit after receiving the specified number of connections, default unlimited. .IP "\fB\-serverinfo val\fR" 4 .IX Item "-serverinfo val" A file containing one or more blocks of \s-1PEM\s0 data. Each \s-1PEM\s0 block must encode a \s-1TLS\s0 ServerHello extension (2 bytes type, 2 bytes length, followed by \*(L"length\*(R" bytes of extension data). If the client sends an empty \s-1TLS\s0 ClientHello extension matching the type, the corresponding ServerHello extension will be returned. .IP "\fB\-certform PEM|DER\fR" 4 .IX Item "-certform PEM|DER" The certificate format to use: \s-1DER\s0 or \s-1PEM. PEM\s0 is the default. .IP "\fB\-key infile\fR" 4 .IX Item "-key infile" The private key to use. If not specified then the certificate file will be used. .IP "\fB\-keyform format\fR" 4 .IX Item "-keyform format" The private format to use: \s-1DER\s0 or \s-1PEM.

As noted above some cipher suites require a certificate containing a key of a certain type. Some cipher suites need a certificate carrying an \s-1RSA\s0 key and some a \s-1DSS\s0 (\s-1DSA\s0) key. By using \s-1RSA\s0 and \s-1DSS\s0 certificates and keys a server can support clients which only support \s-1RSA\s0 or \s-1DSS\s0 cipher suites by using an appropriate certificate. .IP "\fB\-dcert_chain\fR" 4 .IX Item "-dcert_chain" A file containing trusted certificates to use when attempting to build the server certificate chain when a certificate specified via the \fB\-dcert\fR option is in use. .IP "\fB\-dcertform PEM|DER\fR, \fB\-dkeyform PEM|DER\fR, \fB\-dpass val\fR" 4 .IX Item "-dcertform PEM|DER, -dkeyform PEM|DER, -dpass val" Additional certificate and private key format and passphrase respectively. .IP "\fB\-xkey infile\fR, \fB\-xcert infile\fR, \fB\-xchain\fR" 4 .IX Item "-xkey infile, -xcert infile, -xchain" Specify an extra certificate, private key and certificate chain. These behave in the same manner as the \fB\-cert\fR, \fB\-key\fR and \fB\-cert_chain\fR options. When specified, the callback returning the first valid chain will be in use by the server. .IP "\fB\-xchain_build\fR" 4 .IX Item "-xchain_build" Specify whether the application should build the certificate chain to be provided to the client for the extra certificates provided via \fB\-xkey infile\fR, \&\fB\-xcert infile\fR, \fB\-xchain\fR options. .IP "\fB\-xcertform PEM|DER\fR, \fB\-xkeyform PEM|DER\fR" 4 .IX Item "-xcertform PEM|DER, -xkeyform PEM|DER" Extra certificate and private key format respectively. .IP "\fB\-nbio_test\fR" 4 .IX Item "-nbio_test" Tests non blocking I/O. .IP "\fB\-crlf\fR" 4 .IX Item "-crlf" This option translated a line feed from the terminal into \s-1CR+LF.\s0 .IP "\fB\-debug\fR" 4 .IX Item "-debug" Print extensive debugging information including a hex dump of all traffic. .IP "\fB\-msg\fR" 4 .IX Item "-msg" Show all protocol messages with hex dump. .IP "\fB\-msgfile outfile\fR" 4 .IX Item "-msgfile outfile" File to send output of \fB\-msg\fR or \fB\-trace\fR to, default standard output. .IP "\fB\-state\fR" 4 .IX Item "-state" Prints the \s-1SSL\s0 session states. .IP "\fB\-CAfile infile\fR" 4 .IX Item "-CAfile infile" A file containing trusted certificates to use during client authentication and to use when attempting to build the server certificate chain. The list is also used in the list of acceptable client CAs passed to the client when a certificate is requested. .IP "\fB\-CApath dir\fR" 4 .IX Item "-CApath dir" The directory to use for client certificate verification. This directory must be in \*(L"hash format\*(R", see \fBverify\fR\|(1) for more information. These are also used when building the server certificate chain. .IP "\fB\-chainCApath dir\fR" 4 .IX Item "-chainCApath dir" The directory to use for building the chain provided to the client. This directory must be in \*(L"hash format\*(R", see \fBverify\fR\|(1) for more information. .IP "\fB\-chainCAfile file\fR" 4 .IX Item "-chainCAfile file" A file containing trusted certificates to use when attempting to build the server certificate chain. .IP "\fB\-no\-CAfile\fR" 4 .IX Item "-no-CAfile" Do not load the trusted \s-1CA\s0 certificates from the default file location. .IP "\fB\-no\-CApath\fR" 4 .IX Item "-no-CApath" Do not load the trusted \s-1CA\s0 certificates from the default directory location. .IP "\fB\-nocert\fR" 4 .IX Item "-nocert" If this option is set then no certificate is used. This restricts the cipher suites available to the anonymous ones (currently just anonymous \&\s-1DH\s0). .IP "\fB\-quiet\fR" 4 .IX Item "-quiet" Inhibit printing of session and certificate information. .IP "\fB\-www\fR" 4 .IX Item "-www" Sends a status message back to the client when it connects. This includes information about the ciphers used and various session parameters. The output is in \s-1HTML\s0 format so this option will normally be used with a web browser. Cannot be used in conjunction with \fB\-early_data\fR. .IP "\fB\-WWW\fR" 4 .IX Item "-WWW" Emulates a simple web server. Pages will be resolved relative to the current directory, for example if the \s-1URL\s0 https://myhost/page.html is requested the file ./page.html will be loaded. Cannot be used in conjunction with \fB\-early_data\fR. .IP "\fB\-tlsextdebug\fR" 4 .IX Item "-tlsextdebug" Print a hex dump of any \s-1TLS\s0 extensions received from the server. .IP "\fB\-HTTP\fR" 4 .IX Item "-HTTP" Emulates a simple web server. Pages will be resolved relative to the current directory, for example if the \s-1URL\s0 https://myhost/page.html is requested the file ./page.html will be loaded. The files loaded are assumed to contain a complete and correct \s-1HTTP\s0 response (lines that are part of the \s-1HTTP\s0 response line and headers must end with \s-1CRLF\s0). Cannot be used in conjunction with \fB\-early_data\fR. .IP "\fB\-id_prefix val\fR" 4 .IX Item "-id_prefix val" Generate \s-1SSL/TLS\s0 session IDs prefixed by \fBval\fR. This is mostly useful for testing any \s-1SSL/TLS\s0 code (e.g. proxies) that wish to deal with multiple servers, when each of which might be generating a unique range of session IDs (e.g. with a certain prefix). .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fB\-verify_return_error\fR" 4 .IX Item "-verify_return_error" Verification errors normally just print a message but allow the connection to continue, for debugging purposes. If this option is used, then verification errors close the connection. .IP "\fB\-status\fR" 4 .IX Item "-status" Enables certificate status request support (aka \s-1OCSP\s0 stapling). .IP "\fB\-status_verbose\fR" 4 .IX Item "-status_verbose" Enables certificate status request support (aka \s-1OCSP\s0 stapling) and gives a verbose printout of the \s-1OCSP\s0 response. .IP "\fB\-status_timeout int\fR" 4 .IX Item "-status_timeout int" Sets the timeout for \s-1OCSP\s0 response to \fBint\fR seconds. .IP "\fB\-status_url val\fR" 4 .IX Item "-status_url val" Sets a fallback responder \s-1URL\s0 to use if no responder \s-1URL\s0 is present in the server certificate. Without this option an error is returned if the server certificate does not contain a responder address. .IP "\fB\-status_file infile\fR" 4 .IX Item "-status_file infile" Overrides any \s-1OCSP\s0 responder URLs from the certificate and always provides the \&\s-1OCSP\s0 Response stored in the file. The file must be in \s-1DER\s0 format. .IP "\fB\-trace\fR" 4 .IX Item "-trace" Show verbose trace output of protocol messages. OpenSSL needs to be compiled with \fBenable-ssl-trace\fR for this option to work. .IP "\fB\-brief\fR" 4 .IX Item "-brief" Provide a brief summary of connection parameters instead of the normal verbose output. .IP "\fB\-rev\fR" 4 .IX Item "-rev" Simple test server which just reverses the text received from the client and sends it back to the server. Also sets \fB\-brief\fR. Cannot be used in conjunction with \fB\-early_data\fR. .IP "\fB\-async\fR" 4 .IX Item "-async" Switch on asynchronous mode. Cryptographic operations will be performed asynchronously. This will only have an effect if an asynchronous capable engine is also used via the \fB\-engine\fR option. For test purposes the dummy async engine (dasync) can be used (if available). .IP "\fB\-max_send_frag +int\fR" 4 .IX Item "-max_send_frag +int" The maximum size of data fragment to send. See \fBSSL_CTX_set_max_send_fragment\fR\|(3) for further information. .IP "\fB\-split_send_frag +int\fR" 4 .IX Item "-split_send_frag +int" The size used to split data for encrypt pipelines. If more data is written in one go than this value then it will be split into multiple pipelines, up to the maximum number of pipelines defined by max_pipelines. This only has an effect if a suitable cipher suite has been negotiated, an engine that supports pipelining has been loaded, and max_pipelines is greater than 1. See \&\fBSSL_CTX_set_split_send_fragment\fR\|(3) for further information. .IP "\fB\-max_pipelines +int\fR" 4 .IX Item "-max_pipelines +int" The maximum number of encrypt/decrypt pipelines to be used. This will only have an effect if an engine has been loaded that supports pipelining (e.g. the dasync engine) and a suitable cipher suite has been negotiated. The default value is 1. See \fBSSL_CTX_set_max_pipelines\fR\|(3) for further information. .IP "\fB\-read_buf +int\fR" 4 .IX Item "-read_buf +int" The default read buffer size to be used for connections. This will only have an effect if the buffer size is larger than the size that would otherwise be used and pipelining is in use (see \fBSSL_CTX_set_default_read_buffer_len\fR\|(3) for further information). .IP "\fB\-ssl2\fR, \fB\-ssl3\fR, \fB\-tls1\fR, \fB\-tls1_1\fR, \fB\-tls1_2\fR, \fB\-tls1_3\fR, \fB\-no_ssl2\fR, \fB\-no_ssl3\fR, \fB\-no_tls1\fR, \fB\-no_tls1_1\fR, \fB\-no_tls1_2\fR, \fB\-no_tls1_3\fR" 4 .IX Item "-ssl2, -ssl3, -tls1, -tls1_1, -tls1_2, -tls1_3, -no_ssl2, -no_ssl3, -no_tls1, -no_tls1_1, -no_tls1_2, -no_tls1_3" These options require or disable the use of the specified \s-1SSL\s0 or \s-1TLS\s0 protocols. By default \fBs_server\fR will negotiate the highest mutually supported protocol version. When a specific \s-1TLS\s0 version is required, only that version will be accepted from the client. Note that not all protocols and flags may be available, depending on how OpenSSL was built. .IP "\fB\-bugs\fR" 4 .IX Item "-bugs" There are several known bugs in \s-1SSL\s0 and \s-1TLS\s0 implementations. Adding this option enables various workarounds. .IP "\fB\-no_comp\fR" 4 .IX Item "-no_comp" Disable negotiation of \s-1TLS\s0 compression. \&\s-1TLS\s0 compression is not recommended and is off by default as of OpenSSL 1.1.0. .IP "\fB\-comp\fR" 4 .IX Item "-comp" Enable negotiation of \s-1TLS\s0 compression. This option was introduced in OpenSSL 1.1.0. \&\s-1TLS\s0 compression is not recommended and is off by default as of OpenSSL 1.1.0. .IP "\fB\-no_ticket\fR" 4 .IX Item "-no_ticket" Disable RFC4507bis session ticket support. This option has no effect if TLSv1.3 is negotiated. See \fB\-num_tickets\fR. .IP "\fB\-num_tickets\fR" 4 .IX Item "-num_tickets" Control the number of tickets that will be sent to the client after a full handshake in TLSv1.3. The default number of tickets is 2. This option does not affect the number of tickets sent after a resumption handshake. .IP "\fB\-serverpref\fR" 4 .IX Item "-serverpref" Use the server's cipher preferences, rather than the client's preferences. .IP "\fB\-prioritize_chacha\fR" 4 .IX Item "-prioritize_chacha" Prioritize ChaCha ciphers when preferred by clients. Requires \fB\-serverpref\fR. .IP "\fB\-no_resumption_on_reneg\fR" 4 .IX Item "-no_resumption_on_reneg" Set the \fB\s-1SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION\s0\fR option. .IP "\fB\-client_sigalgs val\fR" 4 .IX Item "-client_sigalgs val" Signature algorithms to support for client certificate authentication (colon-separated list). .IP "\fB\-named_curve val\fR" 4 .IX Item "-named_curve val" Specifies the elliptic curve to use. \s-1NOTE:\s0 this is single curve, not a list. For a list of all possible curves, use: .Sp .Vb 1 \& $ openssl ecparam \-list_curves .Ve .IP "\fB\-cipher val\fR" 4 .IX Item "-cipher val" This allows the list of TLSv1.2 and below ciphersuites used by the server to be modified. This list is combined with any TLSv1.3 ciphersuites that have been configured. When the client sends a list of supported ciphers the first client cipher also included in the server list is used. Because the client specifies the preference order, the order of the server cipherlist is irrelevant. See the \fBciphers\fR command for more information. .IP "\fB\-ciphersuites val\fR" 4 .IX Item "-ciphersuites val" This allows the list of TLSv1.3 ciphersuites used by the server to be modified. This list is combined with any TLSv1.2 and below ciphersuites that have been configured. When the client sends a list of supported ciphers the first client cipher also included in the server list is used. Because the client specifies the preference order, the order of the server cipherlist is irrelevant. See the \fBciphers\fR command for more information. The format for this list is a simple colon (\*(L":\*(R") separated list of TLSv1.3 ciphersuite names. .IP "\fB\-dhparam infile\fR" 4 .IX Item "-dhparam infile" The \s-1DH\s0 parameter file to use. The ephemeral \s-1DH\s0 cipher suites generate keys using a set of \s-1DH\s0 parameters. If not specified then an attempt is made to load the parameters from the server certificate file. If this fails then a static set of parameters hard coded into the \fBs_server\fR program will be used. .IP "\fB\-attime\fR, \fB\-check_ss_sig\fR, \fB\-crl_check\fR, \fB\-crl_check_all\fR, \fB\-explicit_policy\fR, \fB\-extended_crl\fR, \fB\-ignore_critical\fR, \fB\-inhibit_any\fR, \fB\-inhibit_map\fR, \fB\-no_alt_chains\fR, \fB\-no_check_time\fR, \fB\-partial_chain\fR, \fB\-policy\fR, \fB\-policy_check\fR, \fB\-policy_print\fR, \fB\-purpose\fR, \fB\-suiteB_128\fR, \fB\-suiteB_128_only\fR, \fB\-suiteB_192\fR, \fB\-trusted_first\fR, \fB\-use_deltas\fR, \fB\-auth_level\fR, \fB\-verify_depth\fR, \fB\-verify_email\fR, \fB\-verify_hostname\fR, \fB\-verify_ip\fR, \fB\-verify_name\fR, \fB\-x509_strict\fR" 4 .IX Item "-attime, -check_ss_sig, -crl_check, -crl_check_all, -explicit_policy, -extended_crl, -ignore_critical, -inhibit_any, -inhibit_map, -no_alt_chains, -no_check_time, -partial_chain, -policy, -policy_check, -policy_print, -purpose, -suiteB_128, -suiteB_128_only, -suiteB_192, -trusted_first, -use_deltas, -auth_level, -verify_depth, -verify_email, -verify_hostname, -verify_ip, -verify_name, -x509_strict" Set different peer certificate verification options. See the \fBverify\fR\|(1) manual page for details. .IP "\fB\-crl_check\fR, \fB\-crl_check_all\fR" 4 .IX Item "-crl_check, -crl_check_all" Check the peer certificate has not been revoked by its \s-1CA.\s0 The \s-1CRL\s0(s) are appended to the certificate file. With the \fB\-crl_check_all\fR option all CRLs of all CAs in the chain are checked. .IP "\fB\-nbio\fR" 4 .IX Item "-nbio" Turns on non blocking I/O. .IP "\fB\-psk_identity val\fR" 4 .IX Item "-psk_identity val" Expect the client to send \s-1PSK\s0 identity \fBval\fR when using a \s-1PSK\s0 cipher suite, and warn if they do not. By default, the expected \s-1PSK\s0 identity is the string \*(L"Client_identity\*(R". .IP "\fB\-psk_hint val\fR" 4 .IX Item "-psk_hint val" Use the \s-1PSK\s0 identity hint \fBval\fR when using a \s-1PSK\s0 cipher suite. .IP "\fB\-psk val\fR" 4 .IX Item "-psk val" Use the \s-1PSK\s0 key \fBval\fR when using a \s-1PSK\s0 cipher suite. The key is given as a hexadecimal number without leading 0x, for example \-psk 1a2b3c4d. This option must be provided in order to use a \s-1PSK\s0 cipher. .IP "\fB\-psk_session file\fR" 4 .IX Item "-psk_session file" Use the pem encoded \s-1SSL_SESSION\s0 data stored in \fBfile\fR as the basis of a \s-1PSK.\s0 Note that this will only work if TLSv1.3 is negotiated. .IP "\fB\-listen\fR" 4 .IX Item "-listen" This option can only be used in conjunction with one of the \s-1DTLS\s0 options above. With this option \fBs_server\fR will listen on a \s-1UDP\s0 port for incoming connections. Any ClientHellos that arrive will be checked to see if they have a cookie in them or not. Any without a cookie will be responded to with a HelloVerifyRequest. If a ClientHello with a cookie is received then \fBs_server\fR will connect to that peer and complete the handshake. .IP "\fB\-dtls\fR, \fB\-dtls1\fR, \fB\-dtls1_2\fR" 4 .IX Item "-dtls, -dtls1, -dtls1_2" These options make \fBs_server\fR use \s-1DTLS\s0 protocols instead of \s-1TLS.\s0 With \fB\-dtls\fR, \fBs_server\fR will negotiate any supported \s-1DTLS\s0 protocol version, whilst \fB\-dtls1\fR and \fB\-dtls1_2\fR will only support DTLSv1.0 and DTLSv1.2 respectively. .IP "\fB\-sctp\fR" 4 .IX Item "-sctp" Use \s-1SCTP\s0 for the transport protocol instead of \s-1UDP\s0 in \s-1DTLS.\s0 Must be used in conjunction with \fB\-dtls\fR, \fB\-dtls1\fR or \fB\-dtls1_2\fR. This option is only available where OpenSSL has support for \s-1SCTP\s0 enabled. .IP "\fB\-sctp_label_bug\fR" 4 .IX Item "-sctp_label_bug" Use the incorrect behaviour of older OpenSSL implementations when computing endpoint-pair shared secrets for \s-1DTLS/SCTP.\s0 This allows communication with older broken implementations but breaks interoperability with correct implementations. Must be used in conjunction with \fB\-sctp\fR. This option is only available where OpenSSL has support for \s-1SCTP\s0 enabled. .IP "\fB\-no_dhe\fR" 4 .IX Item "-no_dhe" If this option is set then no \s-1DH\s0 parameters will be loaded effectively disabling the ephemeral \s-1DH\s0 cipher suites. .IP "\fB\-alpn val\fR, \fB\-nextprotoneg val\fR" 4 .IX Item "-alpn val, -nextprotoneg val" These flags enable the Application-Layer Protocol Negotiation or Next Protocol Negotiation (\s-1NPN\s0) extension, respectively. \s-1ALPN\s0 is the \&\s-1IETF\s0 standard and replaces \s-1NPN.\s0 The \fBval\fR list is a comma-separated list of supported protocol names. The list should contain the most desirable protocols first. Protocol names are printable \s-1ASCII\s0 strings, for example \*(L"http/1.1\*(R" or \&\*(L"spdy/3\*(R". The flag \fB\-nextprotoneg\fR cannot be specified if \fB\-tls1_3\fR is used. .IP "\fB\-engine val\fR" 4 .IX Item "-engine val" Specifying an engine (by its unique id string in \fBval\fR) will cause \fBs_server\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. .IP "\fB\-keylogfile outfile\fR" 4 .IX Item "-keylogfile outfile" Appends \s-1TLS\s0 secrets to the specified keylog file such that external programs (like Wireshark) can decrypt \s-1TLS\s0 connections. .IP "\fB\-max_early_data int\fR" 4 .IX Item "-max_early_data int" Change the default maximum early data bytes that are specified for new sessions and any incoming early data (when used in conjunction with the \fB\-early_data\fR flag). The default value is approximately 16k. The argument must be an integer greater than or equal to 0. .IP "\fB\-early_data\fR" 4 .IX Item "-early_data" Accept early data where possible. Cannot be used in conjunction with \fB\-www\fR, \&\fB\-WWW\fR, \fB\-HTTP\fR or \fB\-rev\fR. .IP "\fB\-anti_replay\fR, \fB\-no_anti_replay\fR" 4 .IX Item "-anti_replay, -no_anti_replay" Switches replay protection on or off, respectively. Replay protection is on by default unless overridden by a configuration file. When it is on, OpenSSL will automatically detect if a session ticket has been used more than once, TLSv1.3 has been negotiated, and early data is enabled on the server. A full handshake is forced if a session ticket is used a second or subsequent time. Any early data that was sent will be rejected. .SH "CONNECTED COMMANDS" .IX Header "CONNECTED COMMANDS" If a connection request is established with an \s-1SSL\s0 client and neither the \&\fB\-www\fR nor the \fB\-WWW\fR option has been used then normally any data received from the client is displayed and any key presses will be sent to the client. .PP Certain commands are also recognized which perform special operations. These commands are a letter which must appear at the start of a line. They are listed below. .IP "\fBq\fR" 4 .IX Item "q" End the current \s-1SSL\s0 connection but still accept new connections. .IP "\fBQ\fR" 4 .IX Item "Q" End the current \s-1SSL\s0 connection and exit. .IP "\fBr\fR" 4 .IX Item "r" Renegotiate the \s-1SSL\s0 session (TLSv1.2 and below only). .IP "\fBR\fR" 4 .IX Item "R" Renegotiate the \s-1SSL\s0 session and request a client certificate (TLSv1.2 and below only). .IP "\fBP\fR" 4 .IX Item "P" Send some plain text down the underlying \s-1TCP\s0 connection: this should cause the client to disconnect due to a protocol violation. .IP "\fBS\fR" 4 .IX Item "S" Print out some session cache status information. .IP "\fBB\fR" 4 .IX Item "B" Send a heartbeat message to the client (\s-1DTLS\s0 only) .IP "\fBk\fR" 4 .IX Item "k" Send a key update message to the client (TLSv1.3 only) .IP "\fBK\fR" 4 .IX Item "K" Send a key update message to the client and request one back (TLSv1.3 only) .IP "\fBc\fR" 4 .IX Item "c" Send a certificate request to the client (TLSv1.3 only) .SH "NOTES" .IX Header "NOTES" \&\fBs_server\fR can be used to debug \s-1SSL\s0 clients. To accept connections from a web browser the command: .PP .Vb 1 \& openssl s_server \-accept 443 \-www .Ve .PP can be used for example. .PP Although specifying an empty list of CAs when requesting a client certificate is strictly speaking a protocol violation, some \s-1SSL\s0 clients interpret this to mean any \s-1CA\s0 is acceptable. This is useful for debugging purposes. .PP The session parameters can printed out using the \fBsess_id\fR program. .SH "BUGS" .IX Header "BUGS" Because this program has a lot of options and also because some of the techniques used are rather old, the C source of \fBs_server\fR is rather hard to read and not a model of how things should be done. A typical \s-1SSL\s0 server program would be much simpler. .PP The output of common ciphers is wrong: it just gives the list of ciphers that OpenSSL recognizes and the client supports. .PP There should be a way for the \fBs_server\fR program to print out details of any unknown cipher suites a client says it supports. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBSSL_CONF_cmd\fR\|(3), \fBsess_id\fR\|(1), \fBs_client\fR\|(1), \fBciphers\fR\|(1) \&\fBSSL_CTX_set_max_send_fragment\fR\|(3), \&\fBSSL_CTX_set_split_send_fragment\fR\|(3), \&\fBSSL_CTX_set_max_pipelines\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The \-no_alt_chains option was added in OpenSSL 1.1.0. .PP The \&\-allow\-no\-dhe\-kex and \-prioritize_chacha options were added in OpenSSL 1.1.1. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2021 The OpenSSL Project Authors.

It can be used to display certificate information, convert certificates to various forms, sign certificate requests like a \*(L"mini \s-1CA\*(R"\s0 or edit certificate trust settings. .PP Since there are a large number of options they will split up into various sections. .SH "OPTIONS" .IX Header "OPTIONS" .SS "Input, Output, and General Purpose Options" .IX Subsection "Input, Output, and General Purpose Options" .IP "\fB\-help\fR" 4 .IX Item "-help" Print out a usage message. .IP "\fB\-inform DER|PEM\fR" 4 .IX Item "-inform DER|PEM" This specifies the input format normally the command will expect an X509 certificate but this can change if other options such as \fB\-req\fR are present. The \s-1DER\s0 format is the \s-1DER\s0 encoding of the certificate and \s-1PEM\s0 is the base64 encoding of the \s-1DER\s0 encoding with header and footer lines added. The default format is \s-1PEM.\s0 .IP "\fB\-outform DER|PEM\fR" 4 .IX Item "-outform DER|PEM" This specifies the output format, the options have the same meaning and default as the \fB\-inform\fR option. .IP "\fB\-in filename\fR" 4 .IX Item "-in filename" This specifies the input filename to read a certificate from or standard input if this option is not specified. .IP "\fB\-out filename\fR" 4 .IX Item "-out filename" This specifies the output filename to write to or standard output by default. .IP "\fB\-\f(BIdigest\fB\fR" 4 .IX Item "-digest" The digest to use. This affects any signing or display option that uses a message digest, such as the \fB\-fingerprint\fR, \fB\-signkey\fR and \fB\-CA\fR options. Any digest supported by the OpenSSL \fBdgst\fR command can be used. If not specified then \s-1SHA1\s0 is used with \fB\-fingerprint\fR or the default digest for the signing algorithm is used, typically \s-1SHA256.\s0 .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .IP "\fB\-engine id\fR" 4 .IX Item "-engine id" Specifying an engine (by its unique \fBid\fR string) will cause \fBx509\fR to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms. .IP "\fB\-preserve_dates\fR" 4 .IX Item "-preserve_dates" When signing a certificate, preserve the \*(L"notBefore\*(R" and \*(L"notAfter\*(R" dates instead of adjusting them to current time and duration. Cannot be used with the \fB\-days\fR option. .SS "Display Options" .IX Subsection "Display Options" Note: the \fB\-alias\fR and \fB\-purpose\fR options are also display options but are described in the \fB\s-1TRUST SETTINGS\s0\fR section. .IP "\fB\-text\fR" 4 .IX Item "-text" Prints out the certificate in text form. Full details are output including the public key, signature algorithms, issuer and subject names, serial number any extensions present and any trust settings. .IP "\fB\-ext extensions\fR" 4 .IX Item "-ext extensions" Prints out the certificate extensions in text form. Extensions are specified with a comma separated string, e.g., \*(L"subjectAltName,subjectKeyIdentifier\*(R". See the \fBx509v3_config\fR\|(5) manual page for the extension names. .IP "\fB\-certopt option\fR" 4 .IX Item "-certopt option" Customise the output format used with \fB\-text\fR. The \fBoption\fR argument can be a single option or multiple options separated by commas. The \&\fB\-certopt\fR switch may be also be used more than once to set multiple options. See the \fB\s-1TEXT OPTIONS\s0\fR section for more information. .IP "\fB\-noout\fR" 4 .IX Item "-noout" This option prevents output of the encoded version of the certificate. .IP "\fB\-pubkey\fR" 4 .IX Item "-pubkey" Outputs the certificate's SubjectPublicKeyInfo block in \s-1PEM\s0 format. .IP "\fB\-modulus\fR" 4 .IX Item "-modulus" This option prints out the value of the modulus of the public key contained in the certificate. .IP "\fB\-serial\fR" 4 .IX Item "-serial" Outputs the certificate serial number. .IP "\fB\-subject_hash\fR" 4 .IX Item "-subject_hash" Outputs the \*(L"hash\*(R" of the certificate subject name. This is used in OpenSSL to form an index to allow certificates in a directory to be looked up by subject name. .IP "\fB\-issuer_hash\fR" 4 .IX Item "-issuer_hash" Outputs the \*(L"hash\*(R" of the certificate issuer name. .IP "\fB\-ocspid\fR" 4 .IX Item "-ocspid" Outputs the \s-1OCSP\s0 hash values for the subject name and public key. .IP "\fB\-hash\fR" 4 .IX Item "-hash" Synonym for \*(L"\-subject_hash\*(R" for backward compatibility reasons. .IP "\fB\-subject_hash_old\fR" 4 .IX Item "-subject_hash_old" Outputs the \*(L"hash\*(R" of the certificate subject name using the older algorithm as used by OpenSSL before version 1.0.0. .IP "\fB\-issuer_hash_old\fR" 4 .IX Item "-issuer_hash_old" Outputs the \*(L"hash\*(R" of the certificate issuer name using the older algorithm as used by OpenSSL before version 1.0.0. .IP "\fB\-subject\fR" 4 .IX Item "-subject" Outputs the subject name. .IP "\fB\-issuer\fR" 4 .IX Item "-issuer" Outputs the issuer name. .IP "\fB\-nameopt option\fR" 4 .IX Item "-nameopt option" Option which determines how the subject or issuer names are displayed. The \&\fBoption\fR argument can be a single option or multiple options separated by commas. Alternatively the \fB\-nameopt\fR switch may be used more than once to set multiple options. See the \fB\s-1NAME OPTIONS\s0\fR section for more information. .IP "\fB\-email\fR" 4 .IX Item "-email" Outputs the email address(es) if any. .IP "\fB\-ocsp_uri\fR" 4 .IX Item "-ocsp_uri" Outputs the \s-1OCSP\s0 responder address(es) if any. .IP "\fB\-startdate\fR" 4 .IX Item "-startdate" Prints out the start date of the certificate, that is the notBefore date. .IP "\fB\-enddate\fR" 4 .IX Item "-enddate" Prints out the expiry date of the certificate, that is the notAfter date. .IP "\fB\-dates\fR" 4 .IX Item "-dates" Prints out the start and expiry dates of a certificate. .IP "\fB\-checkend arg\fR" 4 .IX Item "-checkend arg" Checks if the certificate expires within the next \fBarg\fR seconds and exits nonzero if yes it will expire or zero if not. .IP "\fB\-fingerprint\fR" 4 .IX Item "-fingerprint" Calculates and outputs the digest of the \s-1DER\s0 encoded version of the entire certificate (see digest options). This is commonly called a \*(L"fingerprint\*(R". Because of the nature of message digests, the fingerprint of a certificate is unique to that certificate and two certificates with the same fingerprint can be considered to be the same. .IP "\fB\-C\fR" 4 .IX Item "-C" This outputs the certificate in the form of a C source file. .SS "Trust Settings" .IX Subsection "Trust Settings" A \fBtrusted certificate\fR is an ordinary certificate which has several additional pieces of information attached to it such as the permitted and prohibited uses of the certificate and an \*(L"alias\*(R". .PP Normally when a certificate is being verified at least one certificate must be \*(L"trusted\*(R". By default a trusted certificate must be stored locally and must be a root \s-1CA:\s0 any certificate chain ending in this \s-1CA\s0 is then usable for any purpose. .PP Trust settings currently are only used with a root \s-1CA.\s0 They allow a finer control over the purposes the root \s-1CA\s0 can be used for. For example a \s-1CA\s0 may be trusted for \s-1SSL\s0 client but not \s-1SSL\s0 server use. .PP See the description of the \fBverify\fR utility for more information on the meaning of trust settings. .PP Future versions of OpenSSL will recognize trust settings on any certificate: not just root CAs. .IP "\fB\-trustout\fR" 4 .IX Item "-trustout" This causes \fBx509\fR to output a \fBtrusted\fR certificate. An ordinary or trusted certificate can be input but by default an ordinary certificate is output and any trust settings are discarded. With the \&\fB\-trustout\fR option a trusted certificate is output. A trusted certificate is automatically output if any trust settings are modified. .IP "\fB\-setalias arg\fR" 4 .IX Item "-setalias arg" Sets the alias of the certificate. This will allow the certificate to be referred to using a nickname for example \*(L"Steve's Certificate\*(R". .IP "\fB\-alias\fR" 4 .IX Item "-alias" Outputs the certificate alias, if any. .IP "\fB\-clrtrust\fR" 4 .IX Item "-clrtrust" Clears all the permitted or trusted uses of the certificate. .IP "\fB\-clrreject\fR" 4 .IX Item "-clrreject" Clears all the prohibited or rejected uses of the certificate. .IP "\fB\-addtrust arg\fR" 4 .IX Item "-addtrust arg" Adds a trusted certificate use. Any object name can be used here but currently only \fBclientAuth\fR (\s-1SSL\s0 client use), \fBserverAuth\fR (\s-1SSL\s0 server use), \fBemailProtection\fR (S/MIME email) and \&\fBanyExtendedKeyUsage\fR are used. As of OpenSSL 1.1.0, the last of these blocks all purposes when rejected or enables all purposes when trusted. Other OpenSSL applications may define additional uses. .IP "\fB\-addreject arg\fR" 4 .IX Item "-addreject arg" Adds a prohibited use. It accepts the same values as the \fB\-addtrust\fR option. .IP "\fB\-purpose\fR" 4 .IX Item "-purpose" This option performs tests on the certificate extensions and outputs the results. For a more complete description see the \fB\s-1CERTIFICATE EXTENSIONS\s0\fR section. .SS "Signing Options" .IX Subsection "Signing Options" The \fBx509\fR utility can be used to sign certificates and requests: it can thus behave like a \*(L"mini \s-1CA\*(R".\s0 .IP "\fB\-signkey arg\fR" 4 .IX Item "-signkey arg" This option causes the input file to be self signed using the supplied private key or engine. The private key's format is specified with the \&\fB\-keyform\fR option. .Sp If the input file is a certificate it sets the issuer name to the subject name (i.e. makes it self signed) changes the public key to the supplied value and changes the start and end dates. The start date is set to the current time and the end date is set to a value determined by the \fB\-days\fR option. Any certificate extensions are retained unless the \fB\-clrext\fR option is supplied; this includes, for example, any existing key identifier extensions. .Sp If the input is a certificate request then a self signed certificate is created using the supplied private key using the subject name in the request. .IP "\fB\-sigopt nm:v\fR" 4 .IX Item "-sigopt nm:v" Pass options to the signature algorithm during sign or verify operations. Names and values of these options are algorithm-specific. .IP "\fB\-passin arg\fR" 4 .IX Item "-passin arg" The key password source. For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fBopenssl\fR\|(1). .IP "\fB\-clrext\fR" 4 .IX Item "-clrext" Delete any extensions from a certificate. This option is used when a certificate is being created from another certificate (for example with the \fB\-signkey\fR or the \fB\-CA\fR options). Normally all extensions are retained. .IP "\fB\-keyform PEM|DER|ENGINE\fR" 4 .IX Item "-keyform PEM|DER|ENGINE" Specifies the format (\s-1DER\s0 or \s-1PEM\s0) of the private key file used in the \&\fB\-signkey\fR option. .IP "\fB\-days arg\fR" 4 .IX Item "-days arg" Specifies the number of days to make a certificate valid for. The default is 30 days. Cannot be used with the \fB\-preserve_dates\fR option. .IP "\fB\-x509toreq\fR" 4 .IX Item "-x509toreq" Converts a certificate into a certificate request. The \fB\-signkey\fR option is used to pass the required private key. .IP "\fB\-req\fR" 4 .IX Item "-req" By default a certificate is expected on input. With this option a certificate request is expected instead. .IP "\fB\-set_serial n\fR" 4 .IX Item "-set_serial n" Specifies the serial number to use. This option can be used with either the \fB\-signkey\fR or \fB\-CA\fR options. If used in conjunction with the \fB\-CA\fR option the serial number file (as specified by the \fB\-CAserial\fR or \&\fB\-CAcreateserial\fR options) is not used. .Sp The serial number can be decimal or hex (if preceded by \fB0x\fR). .IP "\fB\-CA filename\fR" 4 .IX Item "-CA filename" Specifies the \s-1CA\s0 certificate to be used for signing. When this option is present \fBx509\fR behaves like a \*(L"mini \s-1CA\*(R".\s0 The input file is signed by this \&\s-1CA\s0 using this option: that is its issuer name is set to the subject name of the \s-1CA\s0 and it is digitally signed using the CAs private key. .Sp This option is normally combined with the \fB\-req\fR option. Without the \&\fB\-req\fR option the input is a certificate which must be self signed. .IP "\fB\-CAkey filename\fR" 4 .IX Item "-CAkey filename" Sets the \s-1CA\s0 private key to sign a certificate with. If this option is not specified then it is assumed that the \s-1CA\s0 private key is present in the \s-1CA\s0 certificate file. .IP "\fB\-CAserial filename\fR" 4 .IX Item "-CAserial filename" Sets the \s-1CA\s0 serial number file to use. .Sp When creating a certificate with this option, and with the \fB\-CA\fR option, the certificate serial number is stored in the given file. This file consists of one line containing an even number of hex digits with the serial number used last time. After reading this number, it is incremented and used, and the file is updated. .Sp The default filename consists of the \s-1CA\s0 certificate file base name with \&\*(L".srl\*(R" appended. For example if the \s-1CA\s0 certificate file is called \&\*(L"mycacert.pem\*(R" it expects to find a serial number file called \*(L"mycacert.srl\*(R". .Sp If the \fB\-CA\fR option is specified and neither <\-CAserial> or <\-CAcreateserial> is given and the default serial number file does not exist, a random number is generated; this is the recommended practice. .IP "\fB\-CAcreateserial\fR" 4 .IX Item "-CAcreateserial" With this option and the \fB\-CA\fR option the \s-1CA\s0 serial number file is created if it does not exist. A random number is generated, used for the certificate, and saved into the serial number file determined as described above. .IP "\fB\-extfile filename\fR" 4 .IX Item "-extfile filename" File containing certificate extensions to use. If not specified then no extensions are added to the certificate. .IP "\fB\-extensions section\fR" 4 .IX Item "-extensions section" The section to add certificate extensions from. If this option is not specified then the extensions should either be contained in the unnamed (default) section or the default section should contain a variable called \&\*(L"extensions\*(R" which contains the section to use. See the \&\fBx509v3_config\fR\|(5) manual page for details of the extension section format. .IP "\fB\-force_pubkey key\fR" 4 .IX Item "-force_pubkey key" When a certificate is created set its public key to \fBkey\fR instead of the key in the certificate or certificate request. This option is useful for creating certificates where the algorithm can't normally sign requests, for example \s-1DH.\s0 .Sp The format or \fBkey\fR can be specified using the \fB\-keyform\fR option. .SS "Name Options" .IX Subsection "Name Options" The \fBnameopt\fR command line switch determines how the subject and issuer names are displayed. If no \fBnameopt\fR switch is present the default \*(L"oneline\*(R" format is used which is compatible with previous versions of OpenSSL. Each option is described in detail below, all options can be preceded by a \fB\-\fR to turn the option off. Only the first four will normally be used. .IP "\fBcompat\fR" 4 .IX Item "compat" Use the old format. .IP "\fB\s-1RFC2253\s0\fR" 4 .IX Item "RFC2253" Displays names compatible with \s-1RFC2253\s0 equivalent to \fBesc_2253\fR, \fBesc_ctrl\fR, \&\fBesc_msb\fR, \fButf8\fR, \fBdump_nostr\fR, \fBdump_unknown\fR, \fBdump_der\fR, \&\fBsep_comma_plus\fR, \fBdn_rev\fR and \fBsname\fR. .IP "\fBoneline\fR" 4 .IX Item "oneline" A oneline format which is more readable than \s-1RFC2253.\s0 It is equivalent to specifying the \fBesc_2253\fR, \fBesc_ctrl\fR, \fBesc_msb\fR, \fButf8\fR, \fBdump_nostr\fR, \&\fBdump_der\fR, \fBuse_quote\fR, \fBsep_comma_plus_space\fR, \fBspace_eq\fR and \fBsname\fR options. This is the \fIdefault\fR of no name options are given explicitly. .IP "\fBmultiline\fR" 4 .IX Item "multiline" A multiline format. It is equivalent \fBesc_ctrl\fR, \fBesc_msb\fR, \fBsep_multiline\fR, \&\fBspace_eq\fR, \fBlname\fR and \fBalign\fR. .IP "\fBesc_2253\fR" 4 .IX Item "esc_2253" Escape the \*(L"special\*(R" characters required by \s-1RFC2253\s0 in a field. That is \&\fB,+"<>;\fR. Additionally \fB#\fR is escaped at the beginning of a string and a space character at the beginning or end of a string. .IP "\fBesc_2254\fR" 4 .IX Item "esc_2254" Escape the \*(L"special\*(R" characters required by \s-1RFC2254\s0 in a field. That is the \fB\s-1NUL\s0\fR character as well as and \fB()*\fR. .IP "\fBesc_ctrl\fR" 4 .IX Item "esc_ctrl" Escape control characters. That is those with \s-1ASCII\s0 values less than 0x20 (space) and the delete (0x7f) character. They are escaped using the \&\s-1RFC2253\s0 \eXX notation (where \s-1XX\s0 are two hex digits representing the character value). .IP "\fBesc_msb\fR" 4 .IX Item "esc_msb" Escape characters with the \s-1MSB\s0 set, that is with \s-1ASCII\s0 values larger than 127. .IP "\fBuse_quote\fR" 4 .IX Item "use_quote" Escapes some characters by surrounding the whole string with \fB"\fR characters, without the option all escaping is done with the \fB\e\fR character. .IP "\fButf8\fR" 4 .IX Item "utf8" Convert all strings to \s-1UTF8\s0 format first. This is required by \s-1RFC2253.\s0 If you are lucky enough to have a \s-1UTF8\s0 compatible terminal then the use of this option (and \fBnot\fR setting \fBesc_msb\fR) may result in the correct display of multibyte (international) characters. Is this option is not present then multibyte characters larger than 0xff will be represented using the format \eUXXXX for 16 bits and \eWXXXXXXXX for 32 bits. Also if this option is off any UTF8Strings will be converted to their character form first. .IP "\fBignore_type\fR" 4 .IX Item "ignore_type" This option does not attempt to interpret multibyte characters in any way. That is their content octets are merely dumped as though one octet represents each character. This is useful for diagnostic purposes but will result in rather odd looking output. .IP "\fBshow_type\fR" 4 .IX Item "show_type" Show the type of the \s-1ASN1\s0 character string. The type precedes the field contents. For example \*(L"\s-1BMPSTRING:\s0 Hello World\*(R". .IP "\fBdump_der\fR" 4 .IX Item "dump_der" When this option is set any fields that need to be hexdumped will be dumped using the \s-1DER\s0 encoding of the field. Otherwise just the content octets will be displayed. Both options use the \s-1RFC2253\s0 \&\fB#XXXX...\fR format. .IP "\fBdump_nostr\fR" 4 .IX Item "dump_nostr" Dump non character string types (for example \s-1OCTET STRING\s0) if this option is not set then non character string types will be displayed as though each content octet represents a single character. .IP "\fBdump_all\fR" 4 .IX Item "dump_all" Dump all fields. This option when used with \fBdump_der\fR allows the \&\s-1DER\s0 encoding of the structure to be unambiguously determined. .IP "\fBdump_unknown\fR" 4 .IX Item "dump_unknown" Dump any field whose \s-1OID\s0 is not recognised by OpenSSL. .IP "\fBsep_comma_plus\fR, \fBsep_comma_plus_space\fR, \fBsep_semi_plus_space\fR, \fBsep_multiline\fR" 4 .IX Item "sep_comma_plus, sep_comma_plus_space, sep_semi_plus_space, sep_multiline" These options determine the field separators. The first character is between RDNs and the second between multiple AVAs (multiple AVAs are very rare and their use is discouraged). The options ending in \&\*(L"space\*(R" additionally place a space after the separator to make it more readable. The \fBsep_multiline\fR uses a linefeed character for the \s-1RDN\s0 separator and a spaced \fB+\fR for the \s-1AVA\s0 separator. It also indents the fields by four characters. If no field separator is specified then \fBsep_comma_plus_space\fR is used by default. .IP "\fBdn_rev\fR" 4 .IX Item "dn_rev" Reverse the fields of the \s-1DN.\s0 This is required by \s-1RFC2253.\s0 As a side effect this also reverses the order of multiple AVAs but this is permissible. .IP "\fBnofname\fR, \fBsname\fR, \fBlname\fR, \fBoid\fR" 4 .IX Item "nofname, sname, lname, oid" These options alter how the field name is displayed. \fBnofname\fR does not display the field at all. \fBsname\fR uses the \*(L"short name\*(R" form (\s-1CN\s0 for commonName for example). \fBlname\fR uses the long form. \&\fBoid\fR represents the \s-1OID\s0 in numerical form and is useful for diagnostic purpose. .IP "\fBalign\fR" 4 .IX Item "align" Align field values for a more readable output. Only usable with \&\fBsep_multiline\fR. .IP "\fBspace_eq\fR" 4 .IX Item "space_eq" Places spaces round the \fB=\fR character which follows the field name. .SS "Text Options" .IX Subsection "Text Options" As well as customising the name output format, it is also possible to customise the actual fields printed using the \fBcertopt\fR options when the \fBtext\fR option is present. The default behaviour is to print all fields. .IP "\fBcompatible\fR" 4 .IX Item "compatible" Use the old format. This is equivalent to specifying no output options at all. .IP "\fBno_header\fR" 4 .IX Item "no_header" Don't print header information: that is the lines saying \*(L"Certificate\*(R" and \*(L"Data\*(R". .IP "\fBno_version\fR" 4 .IX Item "no_version" Don't print out the version number. .IP "\fBno_serial\fR" 4 .IX Item "no_serial" Don't print out the serial number. .IP "\fBno_signame\fR" 4 .IX Item "no_signame" Don't print out the signature algorithm used. .IP "\fBno_validity\fR" 4 .IX Item "no_validity" Don't print the validity, that is the \fBnotBefore\fR and \fBnotAfter\fR fields. .IP "\fBno_subject\fR" 4 .IX Item "no_subject" Don't print out the subject name. .IP "\fBno_issuer\fR" 4 .IX Item "no_issuer" Don't print out the issuer name. .IP "\fBno_pubkey\fR" 4 .IX Item "no_pubkey" Don't print out the public key. .IP "\fBno_sigdump\fR" 4 .IX Item "no_sigdump" Don't give a hexadecimal dump of the certificate signature. .IP "\fBno_aux\fR" 4 .IX Item "no_aux" Don't print out certificate trust information. .IP "\fBno_extensions\fR" 4 .IX Item "no_extensions" Don't print out any X509V3 extensions. .IP "\fBext_default\fR" 4 .IX Item "ext_default" Retain default extension behaviour: attempt to print out unsupported certificate extensions. .IP "\fBext_error\fR" 4 .IX Item "ext_error" Print an error message for unsupported certificate extensions. .IP "\fBext_parse\fR" 4 .IX Item "ext_parse" \&\s-1ASN1\s0 parse unsupported extensions. .IP "\fBext_dump\fR" 4 .IX Item "ext_dump" Hex dump unsupported extensions. .IP "\fBca_default\fR" 4 .IX Item "ca_default" The value used by the \fBca\fR utility, equivalent to \fBno_issuer\fR, \fBno_pubkey\fR, \&\fBno_header\fR, and \fBno_version\fR. .SH "EXAMPLES" .IX Header "EXAMPLES" Note: in these examples the '\e' means the example should be all on one line. .PP Display the contents of a certificate: .PP .Vb 1 \& openssl x509 \-in cert.pem \-noout \-text .Ve .PP Display the \*(L"Subject Alternative Name\*(R" extension of a certificate: .PP .Vb 1 \& openssl x509 \-in cert.pem \-noout \-ext subjectAltName .Ve .PP Display more extensions of a certificate: .PP .Vb 1 \& openssl x509 \-in cert.pem \-noout \-ext subjectAltName,nsCertType .Ve .PP Display the certificate serial number: .PP .Vb 1 \& openssl x509 \-in cert.pem \-noout \-serial .Ve .PP Display the certificate subject name: .PP .Vb 1 \& openssl x509 \-in cert.pem \-noout \-subject .Ve .PP Display the certificate subject name in \s-1RFC2253\s0 form: .PP .Vb 1 \& openssl x509 \-in cert.pem \-noout \-subject \-nameopt RFC2253 .Ve .PP Display the certificate subject name in oneline form on a terminal supporting \s-1UTF8:\s0 .PP .Vb 1 \& openssl x509 \-in cert.pem \-noout \-subject \-nameopt oneline,\-esc_msb .Ve .PP Display the certificate \s-1SHA1\s0 fingerprint: .PP .Vb 1 \& openssl x509 \-sha1 \-in cert.pem \-noout \-fingerprint .Ve .PP Convert a certificate from \s-1PEM\s0 to \s-1DER\s0 format: .PP .Vb 1 \& openssl x509 \-in cert.pem \-inform PEM \-out cert.der \-outform DER .Ve .PP Convert a certificate to a certificate request: .PP .Vb 1 \& openssl x509 \-x509toreq \-in cert.pem \-out req.pem \-signkey key.pem .Ve .PP Convert a certificate request into a self signed certificate using extensions for a \s-1CA:\s0 .PP .Vb 2 \& openssl x509 \-req \-in careq.pem \-extfile openssl.cnf \-extensions v3_ca \e \& \-signkey key.pem \-out cacert.pem .Ve .PP Sign a certificate request using the \s-1CA\s0 certificate above and add user certificate extensions: .PP .Vb 2 \& openssl x509 \-req \-in req.pem \-extfile openssl.cnf \-extensions v3_usr \e \& \-CA cacert.pem \-CAkey key.pem \-CAcreateserial .Ve .PP Set a certificate to be trusted for \s-1SSL\s0 client use and change set its alias to \&\*(L"Steve's Class 1 \s-1CA\*(R"\s0 .PP .Vb 2 \& openssl x509 \-in cert.pem \-addtrust clientAuth \e \& \-setalias "Steve\*(Aqs Class 1 CA" \-out trust.pem .Ve .SH "NOTES" .IX Header "NOTES" The \s-1PEM\s0 format uses the header and footer lines: .PP .Vb 2 \& \-\-\-\-\-BEGIN CERTIFICATE\-\-\-\-\- \& \-\-\-\-\-END CERTIFICATE\-\-\-\-\- .Ve .PP it will also handle files containing: .PP .Vb 2 \& \-\-\-\-\-BEGIN X509 CERTIFICATE\-\-\-\-\- \& \-\-\-\-\-END X509 CERTIFICATE\-\-\-\-\- .Ve .PP Trusted certificates have the lines .PP .Vb 2 \& \-\-\-\-\-BEGIN TRUSTED CERTIFICATE\-\-\-\-\- \& \-\-\-\-\-END TRUSTED CERTIFICATE\-\-\-\-\- .Ve .PP The conversion to \s-1UTF8\s0 format used with the name options assumes that T61Strings use the \s-1ISO8859\-1\s0 character set. This is wrong but Netscape and \s-1MSIE\s0 do this as do many certificates. So although this is incorrect it is more likely to display the majority of certificates correctly. .PP The \fB\-email\fR option searches the subject name and the subject alternative name extension. Only unique email addresses will be printed out: it will not print the same address more than once. .SH "CERTIFICATE EXTENSIONS" .IX Header "CERTIFICATE EXTENSIONS" The \fB\-purpose\fR option checks the certificate extensions and determines what the certificate can be used for. The actual checks done are rather complex and include various hacks and workarounds to handle broken certificates and software. .PP The same code is used when verifying untrusted certificates in chains so this section is useful if a chain is rejected by the verify code. .PP The basicConstraints extension \s-1CA\s0 flag is used to determine whether the certificate can be used as a \s-1CA.\s0 If the \s-1CA\s0 flag is true then it is a \s-1CA,\s0 if the \s-1CA\s0 flag is false then it is not a \s-1CA.\s0 \fBAll\fR CAs should have the \&\s-1CA\s0 flag set to true. .PP If the basicConstraints extension is absent then the certificate is considered to be a \*(L"possible \s-1CA\*(R"\s0 other extensions are checked according to the intended use of the certificate. A warning is given in this case because the certificate should really not be regarded as a \s-1CA:\s0 however it is allowed to be a \s-1CA\s0 to work around some broken software. .PP If the certificate is a V1 certificate (and thus has no extensions) and it is self signed it is also assumed to be a \s-1CA\s0 but a warning is again given: this is to work around the problem of Verisign roots which are V1 self signed certificates. .PP If the keyUsage extension is present then additional restraints are made on the uses of the certificate. A \s-1CA\s0 certificate \fBmust\fR have the keyCertSign bit set if the keyUsage extension is present. .PP The extended key usage extension places additional restrictions on the certificate uses. If this extension is present (whether critical or not) the key can only be used for the purposes specified. .PP A complete description of each test is given below. The comments about basicConstraints and keyUsage and V1 certificates above apply to \fBall\fR \&\s-1CA\s0 certificates. .IP "\fB\s-1SSL\s0 Client\fR" 4 .IX Item "SSL Client" The extended key usage extension must be absent or include the \*(L"web client authentication\*(R" \s-1OID.\s0 keyUsage must be absent or it must have the digitalSignature bit set. Netscape certificate type must be absent or it must have the \s-1SSL\s0 client bit set. .IP "\fB\s-1SSL\s0 Client \s-1CA\s0\fR" 4 .IX Item "SSL Client CA" The extended key usage extension must be absent or include the \*(L"web client authentication\*(R" \s-1OID.\s0 Netscape certificate type must be absent or it must have the \s-1SSL CA\s0 bit set: this is used as a work around if the basicConstraints extension is absent. .IP "\fB\s-1SSL\s0 Server\fR" 4 .IX Item "SSL Server" The extended key usage extension must be absent or include the \*(L"web server authentication\*(R" and/or one of the \s-1SGC\s0 OIDs. keyUsage must be absent or it must have the digitalSignature, the keyEncipherment set or both bits set. Netscape certificate type must be absent or have the \s-1SSL\s0 server bit set. .IP "\fB\s-1SSL\s0 Server \s-1CA\s0\fR" 4 .IX Item "SSL Server CA" The extended key usage extension must be absent or include the \*(L"web server authentication\*(R" and/or one of the \s-1SGC\s0 OIDs. Netscape certificate type must be absent or the \s-1SSL CA\s0 bit must be set: this is used as a work around if the basicConstraints extension is absent. .IP "\fBNetscape \s-1SSL\s0 Server\fR" 4 .IX Item "Netscape SSL Server" For Netscape \s-1SSL\s0 clients to connect to an \s-1SSL\s0 server it must have the keyEncipherment bit set if the keyUsage extension is present. This isn't always valid because some cipher suites use the key for digital signing. Otherwise it is the same as a normal \s-1SSL\s0 server. .IP "\fBCommon S/MIME Client Tests\fR" 4 .IX Item "Common S/MIME Client Tests" The extended key usage extension must be absent or include the \*(L"email protection\*(R" \s-1OID.\s0 Netscape certificate type must be absent or should have the S/MIME bit set. If the S/MIME bit is not set in Netscape certificate type then the \s-1SSL\s0 client bit is tolerated as an alternative but a warning is shown: this is because some Verisign certificates don't set the S/MIME bit. .IP "\fBS/MIME Signing\fR" 4 .IX Item "S/MIME Signing" In addition to the common S/MIME client tests the digitalSignature bit or the nonRepudiation bit must be set if the keyUsage extension is present. .IP "\fBS/MIME Encryption\fR" 4 .IX Item "S/MIME Encryption" In addition to the common S/MIME tests the keyEncipherment bit must be set if the keyUsage extension is present. .IP "\fBS/MIME \s-1CA\s0\fR" 4 .IX Item "S/MIME CA" The extended key usage extension must be absent or include the \*(L"email protection\*(R" \s-1OID.\s0 Netscape certificate type must be absent or must have the S/MIME \s-1CA\s0 bit set: this is used as a work around if the basicConstraints extension is absent. .IP "\fB\s-1CRL\s0 Signing\fR" 4 .IX Item "CRL Signing" The keyUsage extension must be absent or it must have the \s-1CRL\s0 signing bit set. .IP "\fB\s-1CRL\s0 Signing \s-1CA\s0\fR" 4 .IX Item "CRL Signing CA" The normal \s-1CA\s0 tests apply. Except in this case the basicConstraints extension must be present. .SH "BUGS" .IX Header "BUGS" Extensions in certificates are not transferred to certificate requests and vice versa. .PP It is possible to produce invalid certificates or requests by specifying the wrong private key or using inconsistent options in some cases: these should be checked. .PP There should be options to explicitly set such things as start and end dates rather than an offset from the current time. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBreq\fR\|(1), \fBca\fR\|(1), \fBgenrsa\fR\|(1), \&\fBgendsa\fR\|(1), \fBverify\fR\|(1), \&\fBx509v3_config\fR\|(5) .SH "HISTORY" .IX Header "HISTORY" The hash algorithm used in the \fB\-subject_hash\fR and \fB\-issuer_hash\fR options before OpenSSL 1.0.0 was based on the deprecated \s-1MD5\s0 algorithm and the encoding of the distinguished name. In OpenSSL 1.0.0 and later it is based on a canonical version of the \s-1DN\s0 using \s-1SHA1.\s0 This means that any directories using the old form must have their links rebuilt using \fBc_rehash\fR or similar. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2022 The OpenSSL Project Authors.
