[Openid-specs-ab] JSON Web Key (JWK) Specification

[Mike Jones]

I've posted the JSON Web Key (JWK) specification<http://self-issued.info/docs/draft-jones-json-web-key.html> for representing public keys as JSON objects based on the decisions made at the last IIW<http://self-issued.info/?p=390>.  The introduction to the spec reads:

A JSON Web Key (JWK) is a JSON data structure that represents a set of public keys as a JSON object. The JWK format is used to represent bare keys; representing certificate chains is an explicit non-goal of this specification. JSON Web Keys are referenced in JSON Web Signatures (JWSs) using the jku (JSON Key URL) header parameter.

An example from the spec is:

{"keyvalues":
  [
    {"algorithm":"ECDSA",
     "curve":"P-256",
     "x":"MKBCTNIcKUSDii11ySs3526iDZ8AiTo7Tu6KPAqv7D4",
     "y":"4Etl6SRW2YiLUrN5vfvVHuhp7x8PxltmWWlbbM4IFyM",
     "keyid":"1"},

    {"algorithm":"RSA",
      "modulus": "0vx7agoebGcQSuuPiLJXZptN9nndrQmbXEps2aiAFbWhM78LhWx4cbbfAAtVT86zwu1RK7aPFFxuhDR1L6tSoc_BJECPebWKRXjBZCiFV4n3oknjhMstn64tZ_2W-5JsGY4Hc5n9yBXArwl93lqt7_RN5w6Cf0h4QyQ5v-65YGjQR0_FDW2QvzqY368QQMicAtaSqzs8KJZgnYb9c7d0zgdAZHzu6qMQvRL5hajrn1n91CbOpbISD08qNLyrdkt-bFTWhAI4vMQFh6WeZu0fM4lFd2NcRwr3XPksINHaQ-G_xBniIqbw0Ls1jF44-csFCur-kEgU8awapJzKnqDKgw",
     "exponent":"AQAB",
     "keyid":"2011-04-29"}
  ]
}

I also updated the description of the JSON Web Signature (JWS)<http://self-issued.info/docs/draft-jones-json-web-signature.html> header parameter "jku" (JSON Key URL) to reference the JWK spec in draft -02<http://self-issued.info/docs/draft-jones-json-web-signature-02.html>.
