@daveDavid Roetzel @renchapRenaud Chaput When implementing RFC 9421 signature verification, what algorithm do you default to when the alg parameter is not specified in the signature parameters?

RFC 9421: HTTP Message Signatures

This document describes a mechanism for creating, encoding, and verifying digital signatures or message authentication codes over components of an HTTP message. This mechanism supports use cases where the full HTTP message may not be known to the signer and where the message may be transformed (e.g., by intermediaries) before reaching the verifier. This document also describes a means for requesting that a signature be applied to a subsequent HTTP message in an ongoing HTTP exchange.

@hongminhee洪民憙 (Hong Minhee) @renchapRenaud Chaput The branch above currently only supports RSASSA-PKCS1-v1_5 as we are still stuck with old RSA keys and the one key per actor limit. We are looking at FEP-521a to improve this, but this will have to come later.
