                        JSON Web Signature (JWS)

Abstract

   JSON Web Signature (JWS) represents content secured with digital
   signatures or Message Authentication Codes (MACs) using JSON-based
   data structures.  Cryptographic algorithms and identifiers for use
   with this specification are described in the separate JSON Web
   Algorithms (JWA) specification and an IANA registry defined by that
   specification.  Related encryption capabilities are described in the
   separate JSON Web Encryption (JWE) specification.
