testssl.sh is a free command-line tool that checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more. testssl.sh is free and open-source software. You can use it under the terms of GPLv2, please review the License before using it. Works for Linux, Mac OSX, FreeBSD, NetBSD and WSL/MSYS2/Cygwin out of the box, no need to install or configure something, no gems, CPAN, pip or the like. OpenBSD only needs bash to be postinstalled. You can test any SSL/TLS enabled and STARTTLS service, not only webservers at port 443. Several command line options help you to run your test and configure your output. If a particular check cannot be performed because of a missing capability on your client side, you'll get a warning. You can look at the code, see what's going on and you can change it.
