                   eGenix.com pyOpenSSL Distribution


             An easy-to-install and easy-to-use distribution
             of the pyOpenSSL Python interface for OpenSSL -
            available for Windows, Mac OS X and Unix platforms

This announcement is also available on our web-site for online reading:


The eGenix.com 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/TLS-
aware network applications as well as certificate management tools:


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



This new release of the eGenix.com pyOpenSSL Distribution updates the
included OpenSSL version to 1.0.1c.

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

OpenSSL 1.0.1e includes several important fixes:

 * OpenSSL security advisory: ​http://www.openssl.org/news/secadv_20130204.txt
   - also known as "Lucky 13"

 * OpenSSL security advisory: ​http://www.openssl.org/news/secadv_20130205.txt

 * corrected fix for CVE-2013-0169 in 1.0.1e:

 * fixes the SSL3_GET_RECORD:wrong version number problem:


as well as several other new features compared to 1.0.0:


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 https_client.py 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 for all supported platforms:
Windows x86 and x64, Linux x86 and x64, Mac OS X PPC, x86 and x64.

We've also added egg-file distribution versions of our eGenix.com
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.


The download archives and instructions for installing the package can
be found at:



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.


Commercial support for these packages is available from eGenix.com.
