<p>EVP_SIGNATURE-HMAC, EVP_SIGNATURE-Siphash, EVP_SIGNATURE-Poly1305, EVP_SIGNATURE-CMAC - The legacy <b>EVP_PKEY</b> MAC signature implementations</p>

<h1 id="DESCRIPTION">DESCRIPTION</h1>
|

|
|
|
||
|
|
<p>The algorithms described here have legacy support for creating MACs using <a href="../man3/EVP_DigestSignInit.html">EVP_DigestSignInit(3)</a> and related functions. This is not the preferred way of creating MACs. Instead you should use the newer <a href="../man3/EVP_MAC_init.html">EVP_MAC_init(3)</a> functions. This mechanism is provided for backwards compatibility with older versions of OpenSSL.</p>
|
||
|
|
|
||
|
|
<p>The same signature parameters can be set using EVP_PKEY_CTX_set_params() as can be set via EVP_MAC_CTX_set_params() for the underlying EVP_MAC. See <a href="../man7/EVP_MAC-HMAC.html">EVP_MAC-HMAC(7)</a>, <a href="../man7/EVP_MAC-Siphash.html">EVP_MAC-Siphash(7)</a>, <a href="../man7/EVP_MAC-Poly1305.html">EVP_MAC-Poly1305(7)</a> and <a href="../man7/EVP_MAC-CMAC.html">EVP_MAC-CMAC(7)</a> for details.</p>
|
||
|
|
|
||
|
|
<pre><code> See L<EVP_PKEY-HMAC(7)>, L<EVP_PKEY-Siphash(7)>, L<EVP_PKEY-Poly1305(7)> or
|
||
|
|
L<EVP_PKEY-CMAC(7)> for details about parameters that are supported during the
|
||
|
|
creation of an EVP_PKEY.</code></pre>
