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

This new release of the eGenix.com pyOpenSSL Distribution includes the
following updates:

New in OpenSSL

 * Updated included OpenSSL libraries from OpenSSL 1.0.1p to
   1.0.1q. See https://www.openssl.org/news/secadv/20151203.txt ​for a
   complete list of changes. The following fixes are relevant for
   pyOpenSSL applications:

   - CVE-2015-3194 The signature verification routines will crash with
     a NULL pointer dereference, if presented with an ASN.1 signature
     using the RSA PSS algorithm and absent mask generation function
     parameter. This can be exploited in as DoS attack in applications
     which performs certificate verification.

   - CVE-2015-3195: When presented with a malformed X509_ATTRIBUTE
     structure OpenSSL will leak memory.

   - CVE-2015-3196: If PSK identity hints are received by a
     multi-threaded client, then the values are wrongly updated in the
     parent SSL_CTX structure. This can potentially lead to a double
     free of the identify hint data, leading to a segfault.

 * Updated the Mozilla CA root bundle to version 2015-10-27.

 * Added support to allow building wheels from source or prebuilt

Please see the product changelog for the full set of changes.
