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.
