Re: [OAUTH-WG] Future of PoP Work

Maybe if we reworked the signing doc so content types like xml and json could be signed?  

This would cover for the majority of web api cases. 

Wonder what the advice of the http wg would be on this.

Some would maybe say that it is sub-optimal that the protocol was not initially designed for the constrained environment but I think the benefit of concept validation from web is a bigger plus.

I agree with Mike that we should learn from our own mistakes — and that is precisely the direction that the current HTTP signing draft took. As a result, the base level of functionality is signing the token itself (with a timestamp/nonce) using the key. All of the fiddly HTTP bits that trip people up? Not only are they optional, but it’s explicitly declared what’s covered. Why? Because we’re learning from past mistakes.

Additionally, token binding in OAuth is far from the simple solution that it’s being sold as. The very nature of an access token goes against the original purpose of tying an artifact to a single presentation channel. OAuth clients in the real world need to be able to deal with multiple resource servers and dynamically deployed APIs, and the token binding protocol fundamentally assumes a world where two machines are talking directly to each other.
