[Note: I was assigned draft-ietf-jose-cfrg-curves-03 but have reviewed the most recent revision] This document defines how to use the Diffie-Hellman algorithms "X25519" and "X448" as well as the signature algorithms "Ed25519" and "Ed448" from the IRTF CFRG elliptic curves work in JOSE, and in doing so introduces new a key type and subtypes, and specifies registry additions. Section 3 specifies the application of the algorithms within the JOSE framework. Summary: ready, with very minor nits on formal publication requirements I do not have the cryptographic chops to perform a cryptographic review of this draft. The algorithms being added to JOSE in this document are specified in a CFRG deliverable ( https://datatracker.ietf.org/doc/draft-irtf-cfrg-eddsa/ ), which is currently under development (that is to say, mature but not completed). I am satisfied that this document pays heed to the security considerations in the CFRG document. The document appears complete and ready with respect to the needs of someone implementing this specification. Nits: normative reference to an informational RFC (7748) normative reference to an informational draft (draft-irtf-cfrg-eddsa) later version of draft-irtf-cfrg-eddsa has been published missing reference: "RFC-THIS" in IANA Considerations section Melinda Attachment: signature.asc Description: OpenPGP digital signature
