Summary

As system administrators, we know we sometimes have to create passwords. It might be for ourselves, or when creating them for colleagues and customers. For an easy and quick way of generating random passwords, we can use the OpenSSL utility, part of OpenSSL and LibreSSL. This toolkit is often already installed on systems running Linux. OpenSSL has a randomize function. If we feed the output through the base64 function, the scrambled set of characters can be made more human-friendly.
