PyCA cryptography 1.7 has been released to PyPI. cryptography is a package which provides cryptographic recipes and primitives to Python developers. Our goal is for it to be your "cryptographic standard library". We support Python 2.6-2.7, Python 3.3+, and PyPy. Changelog (https://cryptography.io/en/latest/changelog/#id1): * Support for OpenSSL 1.0.0 has been removed. Users on older version of OpenSSL will need to upgrade. * Added support for Diffie-Hellman key exchange using exchange() * The OS random engine for OpenSSL has been rewritten to improve compatibility with embedded Python and other edge cases. More information about this change can be found in the pull request. Thanks to everyone who helped with this release! The upcoming cryptography 1.8 will (among other features) switch our static wheels to link against OpenSSL 1.1.0. -Paul Kehrer (reaperhulk)
