testssl.sh

Good tool for testing TLS/SSL configs.

Easy button mode

testssl.sh --quiet --warnings batch ip:port

Test just the cert config (if it's self-signed, expired, etc)

testssl.sh -S --quiet ip:port

Test just for RC4 use

testssl.sh --rc4 some.cool.domain.com

Test just for vulnerabilities

testssl.sh --vulnerabilities really.neat.web.site
