Suggestion: look at implementing Crystals-Kyber as a key exchange algorithm in the spec #315

Although standardization process is ongoing, implementations already exist.

IMO post-quantum cryptography shouldn't be implemented or in the spec for at least the next 2 or 3 years, and we shouldn't need to worry about it seriously until 2030-35, which means starting to work on using the then-standards in the DIDComm spec by 2027 maybe.

Adding any kind of specifc algorithms to the current spec isn't necessarily a good idea, even if I agree that Crystals-kyber is a good candidate, I don't think we should be that pro-active on the post-quantum front. We can let the PQ competition finish and see what are the standards everybody ends up using in a few years before doing that move.

That's also the position the WG has gone with as well which we tried to allude to in the spec
