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.
