sslyze 5.0.0b1

Fast and powerful SSL/TLS scanning library.

SSLyze

SSLyze is a fast and powerful SSL/TLS scanning tool and Python library.

SSLyze can analyze the SSL/TLS configuration of a server by connecting to it, in order to ensure that it uses strong encryption settings (certificate, cipher suites, elliptic curves, etc.), and that it is not vulnerable to known TLS attacks (Heartbleed, ROBOT, OpenSSL CCS injection, etc.).

Key features

• Focus on speed and reliability: SSLyze is a battle-tested tool that is used to reliably scan hundreds of thousands of servers every day.
• Simple interface to run SSLyze from CI/CD, in order to continuously enforce strong SSL/TLS configuration. (TODO: Link)
• Fully documented Python API that lets you run scans directly from Python, for example on AWS Lambda or Google Cloud Function.
• Support for comparing a server's SSL/TLS configuration with Mozilla's recommendations. TODO: Link
• Support for scanning non-HTTP servers, including SMTP, XMPP, LDAP, POP, IMAP, RDP, PostGres and FTP.
• Results of a scan can easily be saved to a JSON file for later processing. TODO: Link
• And much more!
