Tools for checking the security settings
SSL & TLS
Server checks via the web
- ssllabs.com offers a great way to check your webserver for misconfigurations
- See https://www.ssllabs.com/ssltest/
- Furthermore, ssllabs.com has a good best practices tutorial, which focuses on avoiding the most common mistakes in SSL
SSL Server certificate installation issues
- https://www.sslshopper.com/ssl-checker.html
- Check SPDY protocol support and basic TLS setup http://spdycheck.org/
- XMPP/Jabber Server check (Client-to-Server and Server-to-Server) https://xmpp.net/
- Luxsci SMTP TLS Checker https://luxsci.com/extranet/tlschecker.html
- DNSsec and DANE support of your domain and e-mail server? https://dane.sys4.de
- http://checktls.com is a tool for testing arbitrary TLS services
- http://tls.secg.org is a tool for testing interoperability of HTTPS implementations for ECC cipher suites
- http://www.whynopadlock.com/ Testing for mixed SSL parts loaded via http that can totally lever your HTTPS
Browser Checks
- Check your browser’s SSL capabilities
- Check Browsers SSL/TLS support and vulnerability to attacks
Command Line Tools
- https://sourceforge.net/projects/sslscan connects to a given SSL service and shows the cipher suites that are offered.
- http://www.bolet.org/TestSSLServer/ tests for BEAST and CRIME vulnerabilities.
- https://github.com/drwetter/testssl.sh checks a server’s service on any port for the support of TLS/SSL ciphers, protocols as well as some cryptographic flaws (CRIME, BREACH, CCS, Heartbleed).

Key length
http://www.keylength.com comprehensive online resource for comparison of key lengths according to common recommendations and standards in cryptography.
Random Number Generators
ENT is a pseudo random number generator sequence tester. Dieharder a random number generator testing tool. CAcert Random another random number generator testing service.
