RAND(1) OpenSSL RAND(1)
NAME
rand - generate pseudo-random bytes
LIBRARY
libcrypto, -lcrypto
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.
