The current Ed25519 OID and EdDSAPublicKey encoding format were taken from https://tools.ietf.org/html/draft-josefsson-pkix-eddsa-04 which is now expired. The EdDSAPrivateKey was never specified in that draft, and was based on PKCS#8.

There is now a new draft from the curdle WG that specifies different OIDs and encodings. We should rename the existing methods (to indicate their deprecation while provide a migration pathway for library users), and add new encoding and decoding methods corresponding to the current draft.
