Same. Since the consensus seems to be ciphersuites, what I think would address my most major concerns: - Make it easier to define new ciphersuites that work the same way as existing ones than ones that somehow work differently (most probably via naming of things). - Write guidance for selection of ciphersuites. - Register all ciphersuites according to the guidance. - Get the compact curve stuff to HPKE KEM registry somehow (since a ciphersuite that warrants one-byte identifier uses one of those KEMs). - Register crv(OKP) values for the X25519/Kyber hybrid and the compact curve stuff (with trivial mapping to HPKE key formats, like x25519 and x448 have currently). > > *Von:* COSE <[email protected]> *Im Auftrag von *Ivaylo Petrov > > *Gesendet:* Dienstag, 5.
