SSLyze v0.7 Released

14 Aug 2013 – Alban Diquet

A new version of SSLyze is now available. SSLyze is a Python tool that can analyze the SSL configuration of a server by connecting to it.


  • Complete rewrite of the OpenSSL wrapper as a C extension
    • SSLyze is now statically linked with the latest version of OpenSSL instead of using the system’s (potentially outdated/broken) OpenSSL library
    • All of SSLyze’s features are now available on all supported platforms (including SSL 2.0, TLS 1.1 and TLS 1.2)
    • Scans are slightly faster
    • Python 2.6 is no longer supported
  • Support for StartTLS FTP, POP, IMAP, LDAP and “auto”. See –starttls
  • Support for OCSP Stapling. See –certinfo
  • Other various improvements that results in SSLyze being more stable/robust


SSLyze requires Python 2.7; the supported platforms are Windows 7 32/64 bits, Linux 32/64 bits and OS X 64 bits. SSLyze is statically linked with OpenSSL 1.0.1e. For this reason, the easiest way to run SSLyze is to download one the following pre-compiled packages:


The following packages were tested on Debian 7 and Ubuntu 13.04.
