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.
