Good eye, James!  Thanks for catching this.  I'll fix it right away.

It turns out that examples are based on the trace captured in February 2013 - well before the Xbox One launch in November 2013.  I'd actually noticed this then and had Xbox correct their code.  But silly me, I failed to uniformly correct it in the draft.

                                                          Thanks again!
                                                          -- Mike

That value uses strings for expiry and not-before dates so it is not a valid JWT; these dates need to be numbers.



3 of the examples in draft-ietf-oauth-proof-of-possession are similarly invalid ("exp" and "iat"); 1 example gets it right.

Yes.  Xbox One and its partners have been using this since its launch.  The following token claims are from a production trace captured in early 2013:



  {

   "iss":"xas.xboxlive.com",

   "aud":"http://auth.xboxlive.com",

   "exp":"1361398824",

   "nbf":"1360189224",

      }

    }

  }

Hi,



Are there any implementations of  draft-ietf-oauth-proof-of-possession?



Thanks!
