eGenix pyOpenSSL Distribution 0.9.0-0.9.8l GA

eGenix is pleased to announce eGenix pyOpenSSL Distribution 0.9.0-0.9.8l for Python 2.3 - 2.6, with support for Windows, Linux and Mac OS X.


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 the included OpenSSL version to 0.9.8l.

The new OpenSSL version includes an important work-around for a serious problem in TLS, the protocol implemented and used by OpenSSL. The Man-in-the-Middle TLS protocol attack was disclosed on 2009-11-05 and is being tracked as CVE-2009-3555.

IMPORTANT: The work-around chosen by the OpenSSL team is to disable SSL session renegotiations altogether. This can cause applications relying on this feature on the client or server side to fail. You can still download the previous version of our pyOpenSSL distribution if you run into such problems.

As always, we provide binaries that include both pyOpenSSL and the necessary OpenSSL libraries for all supported platforms: Windows x86, Linux x86 and x64, Mac OS X PPC and x86.

Due to popular demand, we've also added .egg-file format versions of our pyOpenSSL Distribution for Windows and Linux to the available download options. These makes 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.
