RAND(1SSL) OpenSSL RAND(1SSL)
openssl-rand, rand - generate pseudo-random bytes
openssl rand [-help] [-out file] [-rand file...] [-writerand file]
[-base64] [-hex] num
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.
Print out a usage message.
Write to file instead of standard output.
A file or files containing random data used to seed the random
number generator. Multiple files can be specified separated by an
OS-dependent character. The separator is ; for MS-Windows, , for
OpenVMS, and : for all others.
Writes random data to the specified file upon exit. This can be
used with a subsequent -rand flag.
Perform base64 encoding on the output.
Show the output as a hex string.
