[Openid-specs-fapi] #OBEDocument: OBE JWS Profile [revised draft for review]

This spec seems to be generally solid and well-reasoned.

I am a bit surprised by the requirement to use keys from X.509 certificates in Section 5.3, rather than keys from JWKs.  But I understand that that may be the reality of the targeted deployment environments.

I understand the reference to draft-cavage-http-signatures but everyone should be aware that this is a work in progress and is likely to change.  If you want to keep the reference, the draft should probably explicitly say that the specification uses draft-cavage-http-signatures-10 – even though subsequent and potentially incompatible versions may be published.

The x5t#o header parameter is pretty strange.  If new thumbprint algorithms are needed, it would be better to register new values, like x5t#S256 was, rather than to introduce a level of indirection to determine the digest algorithm.  It’s not the end of the world, but it’s certainly not how the JOSE working group would have added additional digest algorithms.

Thanks for asking for the review.
