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.


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 1.0.1e and include an interesting set of other new features as well:

New in OpenSSL 1.0.1e since our last release for OpenSSL 1.0.1c

OpenSSL 1.0.1e includes several important fixes:

as well as several other new features, fixes vulnerabilities relative to 1.0.1c:

and includes a number of stability enhancements as well as extra protection against attacks:

New in the eGenix pyOpenSSL Distribution

  • Changed the package version scheme to be PEP 386 compatible. The new scheme no longer contains underscores or patch level letters.
  • Added a CA root certificate bundle file ca-bundle.crt, which is created from the current Mozilla root CA certificate list. This allows verifying server certificates without having to rely on the system root CA certificate list. The bundle file will be updated with each new release of eGenix pyOpenSSL. We also make the file available as separate download. Please see the product page for details.
  • Added pyOpenSSL examples/ directory to the source distribution.
  • Added a new OpenSSL.ca_bundle module which provides easy to use access to the embedded ca-bundle.crt file.
  • Added new example to the examples/ directory, which demonstrates setting up an SSL connection and using the new OpenSSL.ca_bundle module.
  • Windows x64 builds now have assembler code turned back on again, after a problem with OpenSSL 1.0.1c.

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

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.
