RAND(1SSL)                          OpenSSL                         RAND(1SSL)

       openssl-rand, rand - generate pseudo-random bytes

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

       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.

           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.

           Perform base64 encoding on the output.

           Show the output as a hex string.
