NAME
       openssl-prime - compute prime numbers

SYNOPSIS
       openssl prime [-help] [-hex] [-generate] [-bits num] [-safe] [-provider name] [-provider-path path] [-provparam
       [name:]key=value] [-propquery propq] [-checks num] [number ...]

DESCRIPTION
       This command checks if the specified numbers are prime.

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

OPTIONS
       -help
	   Display an option summary.

       -hex
	   Generate hex output.

       -generate
	   Generate a prime number.

       -bits num
	   Generate a prime with num bits.

       -safe
	   When	 used  with  -generate, generates a "safe" prime. If the number generated is n, then check that "(n-1)/2" is
	   also prime.

       -provider name
