openssl-rand, rand - generate pseudo-random bytes
] [ -out file
] [ -rand
] [ -base64
] [ -hex
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
in addition to the files given in the -rand
option. A new
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.
- 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 an OS-dependent character. The
separator is ; for MS-Windows, , for OpenVMS, and :
for all others.
- Perform base64 encoding on the output.
- Show the output as a hex string.
