PyCA cryptography 3.4.5 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 3.6+, and PyPy3. Changelog (https://cryptography.io/en/latest/changelog.html#v3-4-5): * Various improvements to type hints. * Lower the minimum supported Rust version (MSRV) to >=1.41.0. This change improves compatibility with system-provided Rust on several Linux distributions. * cryptography will be switching to a new versioning scheme with its next feature release. More information is available in our API stability documentation. -Paul Kehrer (reaperhulk)
