When I proposed the two-signatures approach, I was thinking that both keys would automatically be covered by the whole signature, but looking more closely I see that's not the case, so the benefit's not there. So overall I'm supportive of going back to nested signatures.
I see that you changed oldKey and newKey to thumbprints instead of full JWK objects. Why is that? It seems like it introduces an extra step that is unnecessary, and adds another place where we hardcode a hash function. I'd prefer to keep them as the full JWK objects. Also, why require a distinct nonce on the inner and outer JWS? I would rather require that the nonce and URL parameters must match between the inner and outer JWS. _______________________________________________ Acme mailing list Acme@ietf.org https://www.ietf.org/mailman/listinfo/acme
