JOSE Working Group M. Jones Internet-Draft Microsoft Intended status: Standards Track J. Hildebrand Expires: June 12, 2015 Cisco December 9, 2014 JSON Web Encryption (JWE) draft-ietf-jose-json-web-encryption-38 Abstract JSON Web Encryption (JWE) represents encrypted content using JavaScript Object Notation (JSON) based data structures. 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. Related digital signature and MAC capabilities are described in the separate JSON Web Signature (JWS) specification.
