RAND(1)				    OpenSSL			       RAND(1)

NAME
       openssl-rand, rand - generate pseudo-random bytes

SYNOPSIS
       openssl rand [-help] [-out file]	[-rand file...]	 [-writerand file]
       [-base64] [-hex]	num

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

OPTIONS
       -help
	   Print out a usage message.

       -out file
	   Write to file instead of standard output.

       -rand file...
	   A file or files containing random data used to seed the random
	   number generator.  Multiple files can be specified separated	by an
	   OS-dependent	character.  The	separator is ; for MS-Windows, , for
	   OpenVMS, and	: for all others.

       [-writerand file]
	   Writes random data to the specified file upon exit.	This can be
	   used	with a subsequent -rand	flag.

       -base64
	   Perform base64 encoding on the output.

       -hex
	   Show	the output as a	hex string.
