This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-pyOpenSSL-Distribution-0.13.3.1.0....
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 and OpenSSL versions:
Updated pyOpenSSL to the upstream trunk revision 171 (pyOpenSSL version 0.13.1+).
Added work-around for compiling pyOpenSSL trunk revision 171 on Windows with OpenSSL 1.0.0 and later.
Included support for TLS 1.1 and 1.2 in pyOpenSSL (rev 171). Please see the TLS support section in the documentation for details.
Added SSL.OP_NO_COMPRESSION and SSL.OP_SINGLE_ECDH_USE context options to be able to address the CRIME attack and allow for more secure elliptic curve Diffie-Hellman key exchange setups.
Added HTML Sphinx documentation from the pyOpenSSL trunk version to the package. An online version is available from our website:
Updated the included CA bundles to the latest Mozilla 2014-01-28 version.
Included ca-bundle*.crt files now have the same modification date as the Mozilla certdata.txt file from which they were generated.
Restored compatibility of the ca_bundle module with Python 2.4.
Enhanced the included https_client.py example to show case OpenSSL best practices:
server name parsing (RFC 2818 support will follow in one of the next releases)
SNI (support for TLS extension to support multiple SSL sites on a single host)
setup secure default SSL options
setup secure default SSL cipher suite
use TLS 1.0 - 1.2 only
disable SSL compression negotiation (prevent CRIME attack)
Updated included OpenSSL libraries from OpenSSL 1.0.1e to 1.0.1f. See http://www.openssl.org/news/news.html and http://www.openssl.org/news/vulnerabilities.html for a complete list of changes, most important:
CVE-2013-4353: A carefully crafted invalid TLS handshake could crash OpenSSL with a NULL pointer exception. A malicious server could use this flaw to crash a connecting client.
CVE-2013-6450: A flaw in DTLS handling can cause an application using OpenSSL and DTLS to crash.
CVE-2013-6449: A flaw in OpenSSL can cause an application using OpenSSL to crash when using TLS version 1.2.
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. Please see
for details about our support offerings.
