Feature or enhancement

Proposal:

Support SHA-256 digest authentication following RFC7616 - https://datatracker.ietf.org/doc/html/rfc7616

CPython currently supports MD5 and SHA1 only.

Other possible methods include SHA-256-ness, SHA-512-256 and SHA-512-256-sess which hashlib doesn't currently appear to support out of the box.

Has this already been discussed elsewhere?
