RAND(1) 6/Sep/2001 (0.9.7e) RAND(1)
NAME
rand - generate pseudo-random bytes
SYNOPSIS
openssl rand [-out file] [-randfile(s)] [-base64] 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.
-randfile(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.
