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 random number generater 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 OpenVSM, and : for all others.

?base64

Perform base64 encoding on the output.
