doc,test: clarify ChaCha20-Poly1305 usage #42323

Conversation

The crypto documentation does not list chacha20-poly1305 as a supported AEAD algorithm and omits that the algorithm requires passing the authTagLength option.

This patch changes that and also adds a test to assert that the documented behavior is correct.

Arguably, chacha20-poly1305 should not require the authTagLength option. I'll probably open a separate semver-minor PR to address that and update the documentation accordingly.

Perhaps we should also note that this particular chacha20-poly1305 implementation conforms to RFC 7539 (IIRC)?

Ideally, yes, but I haven't figured out where to best put that information without duplicating it across all relevant functions. Suggestions welcome, otherwise, I think we'll have to gradually improve the documentation over time.

@mscdex #42370 adds it to the existing mentions of chacha20-poly1305.
