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 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
Tag | Description |
-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.
