<p>openssl-prime - compute prime numbers</p>

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

<p><b>openssl prime</b> [<b>-help</b>] [<b>-hex</b>] [<b>-generate</b>] [<b>-bits</b> <i>num</i>] [<b>-safe</b>] [<b>-provider</b> <i>name</i>] [<b>-provider-path</b> <i>path</i>] [<b>-provparam</b> <i>[name:]key=value</i>] [<b>-propquery</b> <i>propq</i>] [<b>-checks</b> <i>num</i>] [<i>number</i> ...]</p>

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

<p>This command checks if the specified numbers are prime.</p>

<p>If no numbers are given on the command line, the <b>-generate</b> flag should be used to generate primes according to the requirements specified by the rest of the flags.</p>
