PyCA cryptography 3.3 released

Show key headers only | View raw

PyCA cryptography 3.3 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 3.6+, and PyPy.

Please note that this is the final version that will support Python 2.7!

Changelog (https://cryptography.io/en/latest/changelog/):
* BACKWARDS INCOMPATIBLE: Support for Python 3.5 has been removed due to
low usage and maintenance burden.
* BACKWARDS INCOMPATIBLE: The GCM and AESGCM now require 64-bit to 1024-bit
(8 byte to 128 byte) initialization vectors. This change is to conform with
an upcoming OpenSSL release that will no longer support sizes outside this
window.
* BACKWARDS INCOMPATIBLE: When deserializing asymmetric keys we now raise
ValueError rather than UnsupportedAlgorithm when an unsupported cipher is
used. This change is to conform with an upcoming OpenSSL release that will
no longer distinguish between error types.
* BACKWARDS INCOMPATIBLE: We no longer allow loading of finite field
Diffie-Hellman parameters of less than 512 bits in length. This change is
to conform with an upcoming OpenSSL release that no longer supports smaller
sizes. These keys were already wildly insecure and should not have been
used in any application outside of testing.
* Updated Windows, macOS, and manylinux wheels to be compiled with OpenSSL
1.1.1i.
* Python 2 support is deprecated in cryptography. This is the last release
that will support Python 2.
* Added the recover_data_from_signature() function to RSAPublicKey for
recovering the signed data from an RSA signature.
