openssl-rand, rand - generate pseudo-random bytes
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.
