RAND(1) OpenSSL RAND(1)NAMErand - generate pseudo-random bytes
openssl rand [-out file] [-randfile(s)] [-base64] num
The rand command outputs num pseudo-random bytes after seeding the ran‐
dom 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 writ‐
ten back if enough seeding was obtained from these sources.
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 speci‐
fied separated by a OS-dependent character. The separator is ; for
MS-Windows, , for OpenVMS, and : for all others.
Perform base64 encoding on the output.
