======= SSLyze

Fast and full-featured SSL scanner.

Description

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.

Key features include:

• Multi-processed and multi-threaded scanning (it's fast)
• 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 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 and FTP
• Support for client certificates when scanning servers that perform mutual authentication
• XML output to further process the scan results
• And much more !

Installation

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. For this reason, the easiest way to run SSLyze is to download one the pre-compiled packages available in the GitHub releases section for this project, at https://github.com/nabla-c0d3/sslyze/releases.

Usage

Command line options

The following command will provide the list of available command line options: $ python sslyze.py -h

Sample command line:

$ python sslyze.py --regular www.isecpartners.com:443 www.google.com

See the test folder for additional examples.

Build / nassl

SSLyze is all Python code but since version 0.7, it uses a custom OpenSSL wrapper written in C called nassl. The pre-compiled packages for SSLyze contain a compiled version of this wrapper in sslyze/nassl. If you want to clone the SSLyze repo, you will have to get a compiled version of nassl from one of the SSLyze packages and copy it to sslyze-master/nassl, in order to get SSLyze to run.

The source code for nassl is hosted at https://github.com/nabla-c0d3/nassl.

Py2exe Build

SSLyze can be packaged as a Windows executable by running the following command:

$ python.exe setup_py2exe.py py2exe
