SSLTest is a command line tool used to test SSL based servers to determine the SSL ciphers and protocols they support. These types of tests are commonly performed during penetration tests and compliance reviews (DSD ISM, PCI-DSS) that include a SSL server in scope. It is a Perl program, that works on Linux, Windows and Mac OS X, and is originally based on Cryptonark by Chris Mahns. It uses OpenSSL to make SSL connections, and test for supported ciphers and protocols.
