PyCA cryptography 2.5 has been released to PyPI. cryptography includes both
high level recipes and low level interfaces to common cryptographic
algorithms such as symmetric ciphers, asymmetric algorithms, message
digests, X509, key derivation functions, and much more. We support Python
2.7, Python 3.4+, and PyPy.

Changelog (https://cryptography.io/en/latest/changelog/#v2-6):


   - *BACKWARDS INCOMPATIBLE:* Removed
   cryptography.hazmat.primitives.asymmetric.utils.encode_rfc6979_signature
    and
   cryptography.hazmat.primitives.asymmetric.utils.decode_rfc6979_signature,
   which had been deprecated for nearly 4 years. Use encode_dss_signature()
   <https://cryptography.io/en/latest/hazmat/primitives/asymmetric/utils/#cryptography.hazmat.primitives.asymmetric.utils.encode_dss_signature>
    and decode_dss_signature()
   <https://cryptography.io/en/latest/hazmat/primitives/asymmetric/utils/#cryptography.hazmat.primitives.asymmetric.utils.decode_dss_signature>
   instead.
   - *BACKWARDS INCOMPATIBLE*: Removed cryptography.x509.Certificate.serial,
   which had been deprecated for nearly 3 years. Use serial_number
   <https://cryptography.io/en/latest/x509/reference/#cryptography.x509.Certificate.serial_number>
    instead.
   - Updated Windows, macOS, and manylinux1 wheels to be compiled with
   OpenSSL 1.1.1b.
   - Added support for Ed448 signing
   <https://cryptography.io/en/latest/hazmat/primitives/asymmetric/ed448/> when
   using OpenSSL 1.1.1b or newer.
   - Added support for Ed25519 signing
   <https://cryptography.io/en/latest/hazmat/primitives/asymmetric/ed25519/>
when
   using OpenSSL 1.1.1b or newer.
   - load_ssh_public_key()
   <https://cryptography.io/en/latest/hazmat/primitives/asymmetric/serialization/#cryptography.hazmat.primitives.serialization.load_ssh_public_key>
can
   now load ed25519 public keys.
   - Add support for easily mapping an object identifier to its elliptic
   curve class viaget_curve_for_oid()
   <https://cryptography.io/en/latest/hazmat/primitives/asymmetric/ec/#cryptography.hazmat.primitives.asymmetric.ec.get_curve_for_oid>
   .
   - Add support for OpenSSL when compiled with the no-engine (
   OPENSSL_NO_ENGINE) flag.
