Yesterday, PyCA cryptography 38.0.2 was released to PyPI. Today, we yanked the release from PyPI due to regressions in OpenSSL that led the OpenSSL team to withdraw OpenSSL 3.0.6 (which PyCA cryptography's wheels include). We expect to issue a follow up release once the OpenSSL team has released OpenSSL 3.0.7. 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. Alex -- All that is necessary for evil to succeed is for good people to do nothing.
