rand(1_000)
RAND(1) OpenSSL RAND(1)
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.
