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       -provider-path path       -propquery propq           See "Provider Options" in openssl(1), provider(7), and property(7).       -checks num           This parameter is ignored.COPYRIGHT       Copyright 2017-2020 The OpenSSL Project Authors.
