            JSON Web Encryption JSON Serialization (JWE-JS)
         draft-jones-json-web-encryption-json-serialization-00

Abstract

   The JSON Web Encryption JSON Serialization (JWE-JS) is a means of
   representing encrypted content using JSON data structures.  This
   specification describes a means of representing secured content as a
   JSON data object (as opposed to the JWE specification, which uses a
   compact serialization with a URL-safe representation).  It enables
   the same content to be encrypted to multiple parties (unlike JWE).
   Cryptographic algorithms and identifiers used with this specification
   are enumerated in the separate JSON Web Algorithms (JWA)
   specification.  The JSON Serialization for related digital signature
   and HMAC functionality is described in the separate JSON Web
   Signature JSON Serialization (JWS-JS) specification.

Internet-Draft       JWE JSON Serialization (JWE-JS)          March 2012

1.  Introduction

   The JSON Web Encryption JSON Serialization (JWE-JS) is a format for
   representing encrypted content as a JSON RFC 4627 [RFC4627] object.
   It enables the same content to be encrypted to multiple parties
   (unlike JWE [JWE].)  The encryption mechanisms are independent of the
   type of content being encrypted.  Cryptographic algorithms and
   identifiers used with this specification are enumerated in the
   separate JSON Web Algorithms (JWA) [JWA] specification.  The JSON
   Serialization for related digital signature and HMAC functionality is
   described in the separate JSON Web Signature JSON Serialization
   (JWS-JS) [JWS-JS] specification.

2.  Terminology

   This specification uses the same terminology as the JSON Web
   Encryption (JWE) [JWE] specification.

3.  JSON Serialization

   The JSON Serialization represents encrypted content as a JSON object
   with members for each of three constituent parts: a "headers" member
