SSLyze is a fast and powerful SSL/TLS scanning library.It allows you to analyze the SSL/TLS configuration of a server by connecting to it, in order to detect various issues (bad certificate, weak cipher suites, Heartbleed, ROBOT, TLS 1.3 support, etc.).

Key features

  •  Fully documented Python API, in order to run scans and process the results directly from Python.
  • Support for TLS 1.3 and early data (0-RTT) testing.
  •  Scans are automatically dispatched among multiple workers, making them very fast.
  •  Performance testing: session resumption and TLS tickets support.
  •  Security testing: weak cipher suites, supported curves, ROBOT, 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.
  •  Scan results can be written to a JSON file for further processing.
