SSL Diagnos is used to test SSL strength; get information about SSL protocols (pct, ssl2, ssl3, tls, dtls) and cipher suites. It can also be used for testing and rating ciphers on SSL clients. It has also specific support for pop3s, sip, smtp and explicit ftps.

Furthermore a separate tool, SSLPressure, not using openssl can be used to check the whole spectrum of possible SSL protocols on a server.
