Description

Ed448/X448 is now defined in draft-ietf-openpgp-crypto-refresh-04.
It's good for GnuPG 2.3 to support this format.

Question is:

  • Can Ed448/X448 be used for v4 key?

Currently, we only allow Ed448/X448 in v5 format. But finish of v5 format will take more time.

We should only allow this for v5. This way we get incentive to move forward. ed448 requires a newer version anyway and thus it is good to take this as an opportunity to also demand AEAD etc.

Meanwhile I have _some_ doubts that the v5 format is a good idea. It will introduce a lot of problems and thus a more lean way of replacing the fingerprint should be re-considered. Even if that means, we have to live with two kinds of fingerprints for a decade or so.
