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

<p>RAND_bytes() generates <b>num</b> random bytes using a cryptographically secure pseudo random generator (CSPRNG) and stores them in <b>buf</b>.</p>

<p>RAND_priv_bytes() has the same semantics as RAND_bytes(). It is intended to be used for generating values that should remain private. If using the default RAND_METHOD, this function uses a separate &quot;private&quot; PRNG instance so
