<h1 id="NAME">NAME</h1>

<p>OpenSSL_add_all_algorithms, OpenSSL_add_all_ciphers, OpenSSL_add_all_digests, EVP_cleanup - add algorithms to internal table</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>#include &lt;openssl/evp.h&gt;</code></pre>

<p>The following functions have been deprecated since OpenSSL 1.1.0, and can be hidden entirely by defining <b>OPENSSL_API_COMPAT</b> with a suitable version value, see <a href="../man7/openssl_user_macros.html">openssl_user_macros(7)</a>:</p>

<pre><code>void OpenSSL_add_all_algorithms(void);
void OpenSSL_add_all_ciphers(void);
void OpenSSL_add_all_digests(void);

void EVP_cleanup(void);</code></pre>

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

<p>OpenSSL keeps an internal table of digest algorithms and ciphers. It uses this table to lookup ciphers via functions such as EVP_get_cipher_byname().</p>

<p>OpenSSL_add_all_digests() adds all digest algorithms to the table.</p>

<p>OpenSSL_add_all_algorithms() adds all algorithms to the table (digests and ciphers).</p>

<p>OpenSSL_add_all_ciphers() adds all encryption algorithms to the table including password based encryption algorithms.</p>

<p>In versions prior to 1.1.0 EVP_cleanup() removed all ciphers and digests from the table. It no longer has any effect in OpenSSL 1.1.0.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>None of the functions return a value.</p>

<h1 id="SEE-ALSO">SEE ALSO</h1>

<h1 id="HISTORY">HISTORY</h1>

<p>The OpenSSL_add_all_algorithms(), OpenSSL_add_all_ciphers(), OpenSSL_add_all_digests(), and EVP_cleanup(), functions were deprecated in OpenSSL 1.1.0 by OPENSSL_init_crypto() and should not be used.</p>
