I'm trying to learn about encryption with the use of openssl on a laptop with Ubuntu.
I'm trying to use the random number generator in openssl.
When I enter openssl rand in the terminal I don't receive any numbers. It takes my
command but does not output anything. I also have tried openssl rand -hex 4
and nothing happens either.
Could some one tell me what I'm not doing or doing wrong. I had no problem using
openssl for encrypting but the random generator is causing me grief.
Thank you for your help in advance.
