sslyze v2.1.4 releases: Fast and powerful SSL/TLS server scanning library

SSLyze

Fast and powerful SSL/TLS server scanning library for Python 2.7 and 3.4+.

Description

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 misconfigurations affecting their SSL/TLS servers.

Key features include:

  • Fully documented Python API, in order to run scans and process the results directly from Python.
  • New: Support for TLS 1.3 (draft 18) and the ROBOT vulnerability.
  • 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.
  • Scan results can be written to an XML or JSON file for further processing.
  • And much more!

How does it work?

SSLyze is all Python code but it uses an OpenSSL wrapper written in C called nassl, which was specifically developed for allowing SSLyze to access the low-level OpenSSL APIs needed to perform deep SSL testing.

Changelog

v2.1.4

  • Fixed crash when scanning servers that only support old versions of SSL/TLS (#386).

Getting started

SSLyze can be installed directly via pip:

pip install --upgrade setuptools
pip install sslyze
sslyze --regular www.yahoo.com:443 www.google.com "[2607:f8b0:400a:807::2004]:443"

It is also easy to directly clone the repository and the fetch the requirements:

git clone https://github.com/nabla-c0d3/sslyze.git
cd sslyze
pip install -r requirements.txt --upgrade
python -m sslyze --regular www.yahoo.com:443 www.google.com "[2607:f8b0:400a:807::2004]:443"

On Linux, the python-dev package needs to be installed first so that the nassl C extension can be compiled:

sudo apt-get install python-dev

SSLyze has been tested on the following platforms: Windows 7 (32 and 64 bits), Debian 7 (32 and 64 bits), macOS Sierra

Usage as a library

SSLyze can be used as a Python module in order to run scans and process the results directly in Python. Full documentation is available here.
