We are moving fast to the encrypted world and the usage of TLS certificates increased dramatically.Transport Layer Security is the main feature of TLS/SSL certificates, but it also aids in performance and SEO.
Now we are preparing for TLS1.3 which is designed which has Enhanced protection and speed by removing old unsafe cryptographic primitives and by reducing network round trips.

In the same hand, it is important to do penetration testing with SSL configured servers to avoid Misconfigurations.In this article, we are to use the tool SSLyze.
SSLyze Fast and Complete SSL Scanner to find Misconfiguration in the servers configured with SSL. It works with Python 2.7 and 3.3+.
root@kali:~# sslyze –regular domain.com
It will check for the Common name with SSL Certificate, Session Renegotiation, Compression, Fingerprints, SAN Domain Entries and Cipher Suites.
sslyze –compression doamin.com
Will print the certificate fields and also the validity against trusted root stores.
sslyze –certinfo=full gbhackers.com
SSLyze can also do session resumptions, it will 100 session resumptions to estimate the resumptions rate.

SSLyze is a very useful tool to find all the Misconfiguration in the server. Soon we expect Poodle and Crime plugins are to be added. It was developed by iSECPartners.
Now you can also use SSL analyzers available online.
