SSLyze

[Premiums]

SSLyze is a Python library and a CLI tool that can analyze the SSL configuration of a server by connecting to it. It is designed to be fast and comprehensive, and should help organizations and testers identify mis-configurations affecting their SSL/TLS servers.
Key features include:

• Fully documented Python API, in order to run scans and process the results directly from Python.
• Scans are automatically dispatched among multiple processes, making them very fast.
• Performance testing: session resumption and TLS tickets support.
• Security testing: weak cipher suites, insecure renegotiation, CRIME, Heartbleed and more.
• Server certificate validation and revocation checking through OCSP stapling.
• Support for StartTLS handshakes on SMTP, XMPP, LDAP, POP, IMAP, RDP, PostGres and FTP.
• Support for client certificates when scanning servers that perform mutual authentication.
• Scan results can be written to an XML or JSON file for further processing.
• And much more!
