PyCA cryptography 1.8 (and 1.8.1) 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: 1.8.1 * Fixed macOS wheels to properly link against 1.1.0 rather than 1.0.2. 1.8 * Added support for Python 3.6. * Windows and macOS wheels now link against OpenSSL 1.1.0. * macOS wheels are no longer universal. This change significantly shrinks the size of the wheels. Users on macOS 32-bit Python (if there are any) should migrate to 64-bit or build their own packages. * Changed ASN.1 dependency from pyasn1 to asn1crypto resulting in a general performance increase when encoding/decoding ASN.1 structures. Also, the ``pyasn1_modules`` test dependency is no longer required. * Added support for update_into on CipherContext. * Added DHPrivateKeyWithSerialization.private_bytes. * Added DHPublicKeyWithSerialization.public_bytes * load_pem_private_key and load_der_private_key now require that ``password`` must be bytes if provided. Previously this was documented but not enforced. * Added support for subgroup order in Diffie-Hellman key exchange. Thanks to all the contributors on this release! -Paul Kehrer (reaperhulk)
