JSON Web Signature (JWS) represents the payload of a JWS as a
base64url-encoded value and uses this value in the JWS Signature
computation. While this enables arbitrary payloads to be integrity
protected, some have described use cases in which the base64url
encoding is unnecessary and/or an impediment to adoption, especially
when the payload is large and/or detached. This specification
defines a means of accommodating these use cases by defining an
option to change the JWS Signing Input computation to not base64url-
encode the payload. This option is intended to broaden the set of
use cases for which the use of JWS is a good fit.
This specification updates RFC 7519 by stating that JSON Web Tokens
(JWTs) MUST NOT use the unencoded payload option defined by this
specification.
This document is a product of the Javascript Object Signing and Encryption Working Group of the IETF.
This is now a Proposed Standard.
