===============================
- Replace PyOpenSSL with Cryptography (260)
- This is a major infrastructure change that replaces core
certificate parsing, key processing, signature validation, and
certificate chain validation functions previously provided by
PyOpenSSL with those provided by Cryptography. Care was taken to
preserve the exisitng API, including exception types, but many
error messages raised in various error conditions have changed. If
you see unexpected behavior and you have reason to believe it is
incorrect, please file an issue.
- Breaking change: the ca_path parameter, previously used to specify
CA certificate stores, is no longer supported. Use the ca_pem_file
parameter instead.
- Raise error when invalid certificate string is passed as input to
signer
- Fix public key matching for ECDSA (245)
