PyCA cryptography 44.0.0 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 7.3.10+. Changelog (https://cryptography.io/en/latest/changelog/#v44-0-0): * BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL < 3.9. * Deprecated Python 3.7 support. Python 3.7 is no longer supported by the Python core team. Support for Python 3.7 will be removed in a future cryptography release. * Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.4.0. * macOS wheels are now built against the macOS 10.13 SDK. Users on older versions of macOS should upgrade, or they will need to build cryptography themselves. * Enforce the RFC 5280 requirement that extended key usage extensions must not be empty. * Added support for timestamp extraction to the MultiFernet class. * Relax the Authority Key Identifier requirements on root CA certificates during X.509 verification to allow fields permitted by RFC 5280 but forbidden by the CA/Browser BRs. * Added support for Argon2id when using OpenSSL 3.2.0+. * Added support for the Admissions certificate extension. * Added basic support for PKCS7 decryption (including S/MIME 3.2) via pkcs7_decrypt_der(), pkcs7_decrypt_pem(), and pkcs7_decrypt_smime(). -Paul Kehrer (reaperhulk)
