testssl.sh is a free Unix command line tool which checks a server's
service on any port for the support of TLS/SSL ciphers, protocols as
well as some cryptographic flaws.
It's designed to provide clear output for a "is this good or bad" decision.
It is working on every Linux distribution which has OpenSSL installed.
As for security reasons some distributors outphase the buggy stuff -
and this is exactly you want to check for - it's recommended to
compile OpenSSL by yourself or check out the OpenSSL binaries below
(Linux). You will get a warning though if your OpenSSL client cannot
perform a specific check, see below.
testssl.sh is portable, it is supposed to work on any other Unix
system (preferably with GNU tools) and on cygwin, supposed it can find
the OpenSSL binary.
