eGenix pyOpenSSL Distribution GA

eGenix is pleased to announce the eGenix pyOpenSSL Distribution for Python 2.4 - 2.7, with support for Windows, Linux and Mac OS X and without the Heartbleed Bug.


The pyOpenSSL Distribution includes everything you need to get started with SSL in Python. It comes with an easy to use installer that includes the most recent OpenSSL library versions in pre-compiled
form, making your application independent of OS provided OpenSSL libraries:

pyOpenSSL is an open-source Python add-on that allows writing SSL-aware networking applications as as certificate managment tools. It uses the OpenSSL library as performant and robust SSL engine.

OpenSSL is an open-source implementation of the SSL/TLS protocol.


This new release of the pyOpenSSL Distribution updates only the included OpenSSL version to address a serious bug in OpenSSL 1.0.1 versions:

New in OpenSSL

    • CVE-2014-0160 ("Heartbleed Bug"): A missing bounds check in the handling of the TLS heartbeat extension can be used to reveal up to 64kB of memory to a connected client or server. This issue did not affect versions of OpenSSL prior to 1.0.1. For information, also have a look at the Heartbleed Bug website.

We have also added .egg-file distribution versions of our pyOpenSSL Distribution for Windows, Linux and Mac OS X to the available download options. These make setups using e.g. zc.buildout and other egg-file based installers a lot easier.


Please visit the eGenix pyOpenSSL Distribution page for downloads, instructions on installation and documentation of the package.


Before installing this version of pyOpenSSL, please make sure that you uninstall any previously installed pyOpenSSL version. Otherwise, you could end up not using the included OpenSSL libs.
