Ed448/X448 defined in draft-ietf-openpgp-crypto-refresh-04
Open, NormalPublic


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.

The branch gniibe/v5/448 has the implementation.

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.
