SSLyze is a Python 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 misconfigurations affecting their SSL servers.

Features

• SSL 2.0/3.0 and TLS 1.0/1.1/1.2 compatibility
• Performance testing: session resumption and TLS tickets support
• Security testing: weak cipher suites, insecure renegation, CRIME and THC-SSL DOS attacks
• Server certificate validation
• Support for StartTLS with SMTP and XMPP, and traffic tunneling through an HTTPS proxy
• Client certificate support for servers performing mutual authentication
• Scan results can be written to an XML file for further processing

New in v0.6:

• Added support for Server Name Indication; see –sni
• Partial results are returned when the server requires client authentication but no client certificate was provided
• Preliminary IPv6 support
• Various bug fixes and better support of client authentication and HTTPS tunneling
