PyCA cryptography 45.0.3 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, X.509, key derivation functions, and much more. We support Python 3.7+, and PyPy3 7.3.11+. Changelog (https://cryptography.io/en/latest/changelog/#v45-0-3): * Fixed decrypting PKCS#8 files encrypted with long salts (this impacts keys encrypted by Bouncy Castle). * Fixed decrypting PKCS#8 files encrypted with DES-CBC-MD5. While wildly insecure, this remains prevalent. Alex -- All that is necessary for evil to succeed is for good people to do nothing.
