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 pyOpenSSL version to 0.10.0 and the included OpenSSL version
Main new features in pyOpenSSL 0.10.0 (from the announcement)
* pyOpenSSL 0.10 exposes several more OpenSSL APIs, including
support for running TLS connections over in-memory BIOs, access
to the OpenSSL random number generator, the ability to pass
subject and issuer parameters when creating an X509Extension
instance, more control over PKCS12 creation and an API for
exporting PKCS12 objects, and APIs for controlling the client CA
list servers send to clients.
* Several bugs have also been fixed, including a crash when
certain X509Extension instances are deallocated, a mis-handling
of the OpenSSL error queue in the X509Name implementation,
Windows build issues, and a possible double free when using a

New features in OpenSSL 1.0.0a since our last release
The main new features in OpenSSL 0.9.8m is the new support for RFC
5746, which addresses the SSL renegotiation problem found in earlier
* RFC 5746 - Transport Layer Security (TLS) Renegotiation
Indication Extension: http://tools.ietf.org/html/rfc5746
* For a complete list of changes see:
Version 0.9.8n fixes this vulnerability (see
* "Record of death" vulnerability in OpenSSL 0.9.8f through
Version 1.0.0 adds many new features, including (see
* Support for Whirlpool hash algorithm
* Support for GOST cipher
Version 1.0.0a fixes two security issues (see
* Invalid ASN1 module definition for CMS.
* Invalid Return value check in pkey_rsa_verifyrecover
New features in the eGenix pyOpenSSL Distribution
* The embedded OpenSSL libs will now look for certificates in
/etc/ssl on Unix platforms and /System/Library/OpenSSL on
Mac OS X
Note that it's usually better to explicitly tell OpenSSL where
to look for trusted certificates via
.load_verify_locations(None, certs_dir) than to rely on the
above defaults using context.set_default_verify_paths()
* Added support for Win64 and precompiled Python 2.6 compatible
binaries for that platform (you can find the OpenSSL libs in
* Added support for Mac OS X 10.6 on Intel x64.
* Added .egg Distributions for Python 2.4 as well (in order to
support Plone 3).
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.
Due to popular demand, we've also added .egg-file format versions of
our eGenix.com pyOpenSSL Distribution for Windows, Linux and Mac OS X
to the available download options.
These makes 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.
