NAME
    rand - generate pseudo-random bytes

SYNOPSIS
    openssl rand [-out file] [-rand file(s)] [-base64] num

DESCRIPTION
    The rand command outputs num pseudo-random bytes after seeding the ran-
    dom 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 writ-
    ten 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 speci-
   fied 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.
