testssl.sh is a free command line tool which checks a server’s service on any port for the support of TLS/SSL ciphers, protocols as well as some flaws. It’s designed to provide a clear output for a “is this good or bad” decision. It works for Linux and BSD out of the box – no need to install or configure something, no gems, CPAN, pip or the like.
If you use the Qualys online SSL checker a lot, you need to try this, it’s very fast if you are experimenting with SSL config options.
