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.
