Is one more secure and "random" than the other?
Is "openssl rand" not secure if the "-rand <file>" option is omitted? I'm guessing openssl may suck from /dev/*random in addition to the optional -rand file?
For years I've been using `openssl rand -base64 N` to generate secrets.
However, I recently saw `dd if=/dev/random bs=N count=1 | openssl
base64` used.
