eGenix is pleased to announce eGenix pyOpenSSL Distribution 0.13.0-1.0.1c for Python 2.4 - 2.7, with support for Windows, Linux and Mac OS X.

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 1.0.1c.

New features in OpenSSL 1.0.1c since our last release for OpenSSL 1.0.0j

OpenSSL 1.0.1c includes several new features:

  • TLS/DTLS heartbeat support
  • Next Protocol Negotiation
  • Support TLS v1.2 and TLS v1.1

as well as several other new features, fixes vulnerabilities relative to 1.0.0j:

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

New features in the eGenix pyOpenSSL Distribution

  • Added the openssl binary to the OpenSSL package directory. This can be used to access OpenSSL functionality not exposed by pyOpenSSL.
  • Changed the Windows OPENSSLDIR default to c:\openssl\ to simplify OpenSSL configuration.
  • Fixed OpenSSL assembler build issues on Windows x64 and Mac OS X PPC/x86.

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.
