- update to 3.3.0
- 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.
- Remove unnecessary dependency virtualenv.
