Allow CPython to build against cryptography libraries lacking BLAKE2 support #117233
Description
Feature or enhancement
Proposal:
As part of a series of changes discussed on the python Ideas board, this issue proposes placing guards around references to BLAKE2's NIDs. This would allow cryptography libraries lacking full BLAKE2 support to be used with CPython.
Has this already been discussed elsewhere?
I have already discussed this feature proposal on Discourse
