OpenSSL - Generate Psuedo Random Passwords

Published: 26-07-2013 | Author: Remy van Elst | Text only version of this article


❗ This post is over ten years old. It may no longer be up to date. Opinions may have changed.

This a snippet to generate a psuedo random password fast via the command line with OpenSSL. It generates a number of random bytes, which can either be output raw, as Base64 or as HEX. The Base64 output is a good password most of the time.
