JSON Web Document (JWD)


JSON Web Document (JWD) is a means of representing optionally signed and/or encrypted JSON content suitable for storage, retrieval, transmission, and display in a graphical user interface. The content of a JWD is used as the payload of a JSON Web Signature (JWS) structure or as the plaintext of a JSON Web Encryption (JWE) structure.

Requirements Language

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].

Table of Contents

1. Introduction

JWD introduces a new set of serializations to JWS and JWE called the Document Serializations. These serializations follow the form of the JSON Serialization and Flattened JSON Serialization described in JWS Section 7.2, except that the payload, integrity-protected header, and non-integrity-protected header contents are all represented as unencoded JSON values and MUST NOT be base64url-encoded.

Signatures present in the data structure MUST be base64url-encoded. Signatures are computed using base64url-encoded JSON values for the payload and integrity-protected headers as in JWS. For a given payload and JOSE Header, the signature(s) of a JWD MUST be identical to signatures computed for semantically equivalent JWT serializations.

2. Terminology

This specification uses terms defined in the JSON Web Token [JWT], JSON Web Signature [JWS], and JSON Web Encryption [JWE] specifications.

These terms are defined by this specification:

JSON Web Document (JWD)

JWS Document Serialization
