<h1 id="DESCRIPTION">DESCRIPTION</h1>
|
|
|
|
<p>The <b>rand</b> command outputs <i>num</i> pseudo-random bytes after seeding the random number generator once. As in other <b>openssl</b> command line tools, PRNG seeding uses the file <i>$HOME/</i><b>.rnd</b> or <b>.rnd</b> in addition to the files given in the <b>-rand</b> option. A new <i>$HOME</i>/<b>.rnd</b> or <b>.rnd</b> file will be written back if enough seeding was obtained from these sources.</p>
