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. |
