NAME

       rand - generate pseudo-random bytes

SYNOPSIS

       openssl rand [-out file] [-rand file(s)] [-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

       -out file
           Write to file instead of standard output.

       -rand file(s)
           Use  specified file or files or EGD socket (see RAND_egd(3)) for seeding the random number generator.
           Multiple files can be specified separated by a OS-dependent character.  The separator is  ;  for  MS-
           Windows, , for OpenVMS, and : for all others.

       -base64
           Perform base64 encoding on the output.

       -hex
           Show the output as a hex string.
