At IIW 2010B, we had a major advancement in the JSON Signature and Encryption Spec. Microsoft, Google, Facebook and me and John Bradley basically converged to a spec. The details has been posted to OpenID Artifact Binding WG list (archive -> http://lists.openid.net/pipermail/openid-specs-ab/Week-of-Mon-20101108/date.html ).
- JSON Token Spec Results at IIW on Tuesday: - JSON Token Encryption Spec Results at IIW on Wednesday: - JSON Token Naming Spec Results at IIW on Wednesday: - JSON Public Key Spec Results at IIW on Thursday: (Source: JSON Token Spec Work at IIW )
In the next couple of weeks, you will see the new spec draft which is going to go for voting, hopefully.
This is an important spec. All of OAuth, OpenID/AB, OpenID/Connect depends on it.
