Re: [OAUTH-WG] Clarification on SD-JWT verification

2023-10-20 Thread Brian Campbell
Agree that it should be clarified. Being precise with language around this stuff is tricky. But my understanding of the intent was to ensure that no digest value is repeated in the whole of the SD-JWT - either in the payload directly or recursively in any Disclosure. Because of the trickiness of la

Re: [OAUTH-WG] SD-JWT Redaction Reasons

2023-10-20 Thread Orie Steele
That's a much better place to communicate redaction reasons. Although if the use case for communicating secured redaction reasons from the holder to the verifier doesn't fit well with SD-JWT spec, it's possible that's a profile specific thing, where interoperability matters less, so it should be c

2023-10-20 Thread Daniel Fett
Hi Jacob, this check is mainly important for the Holder to ensure the integrity of the received SD-JWT. For the Verifier, there is not much to gain by checking this (but it also doesn't hurt either). However, we intended to keep the algorithms for the Holder and Verifier similar and therefor

At least at the moment I don't think that there is a huge need for such a feature. I don't think that we should clutter the existing SD-JWT data structures with such information. If required, it could go into a separate data structure in the SD-JWT, for example a list of JSON pointers with a m

Hello all, Please let me know if there's a better channel to ask questions and/or raise issues with the SD-JWT spec. Currently as part of verification of an SD-JWT the following is stated: *Upon receiving an SD-JWT, a Holder or a Verifier MUST ensure that * - *the Issuer-signed JWT is valid,
