PRIME(1)                            OpenSSL                           PRIME(1)

## NAME

openssl-prime, prime - compute prime numbers

## SYNOPSIS

openssl prime [-help] [-hex] [-generate] [-bits] [-safe] [-checks] [number...]

## DESCRIPTION

The prime 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. [-checks num] Perform the checks num times to see that the generated number is prime. The default is 20.
