JSON Web Encryption (JWE)
Abstract
JSON Web Encryption (JWE) represents encrypted content 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 IANA registries defined by
that specification. Related digital signature and Message
Authentication Code (MAC) capabilities are described in the separate
JSON Web Signature (JWS) specification.
