                           JSON Web Key (JWK)
                    draft-ietf-jose-json-web-key-25

Abstract

   A JSON Web Key (JWK) is a JavaScript Object Notation (JSON) data
   structure that represents a cryptographic key.  This specification
   also defines a JSON Web Key Set (JWK Set) JSON data structure for
   representing a set of JWKs.  Cryptographic algorithms and identifiers
   for use with this specification are described in the separate JSON
   Web Algorithms (JWA) specification and IANA registries defined by
   that specification.
