PyCA cryptography 37.0.0 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, X509, key derivation functions, and much more. We support Python 3.6+, and PyPy3. Changelog (https://cryptography.io/en/latest/changelog/#v37-0-1): * Fixed an issue where parsing an encrypted private key with the public loader functions would hang waiting for console input on OpenSSL 3.0.x rather than raising an error. * Restored some legacy symbols for older pyOpenSSL users. These will be removed again in the future, so pyOpenSSL users should still upgrade to the latest version of that package when they upgrade cryptography. -Paul Kehrer (reaperhulk)
