<p>RAND_cleanup - erase the PRNG state</p>

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

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

#if OPENSSL_API_COMPAT &lt; 0x10100000L
 void RAND_cleanup(void)
 #endif</code></pre>

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

<p>Prior to OpenSSL 1.1.0, RAND_cleanup() released all resources used by the PRNG. As of version 1.1.0, it does nothing and should not be called, since no explicit initialisation or de-initialisation is necessary. See <a href="../man3/OPENSSL_init_crypto.html">OPENSSL_init_crypto(3)</a>.</p>

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

<p>RAND_cleanup() returns no value.</p>

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

<p>RAND_cleanup() was deprecated in OpenSSL 1.1.0; do not use it. See <a href="../man3/OPENSSL_init_crypto.html">OPENSSL_init_crypto(3)</a></p>
