1. Introduction
JSON Web Token (JWT) [JWT] is a JavaScript Object Notation (JSON)
[RFC4627] based security token encoding that enables identity and
security information to be shared across security domains. A
security token is generally issued by an identity provider and
consumed by a relying party that relies on its content to identify
the token's subject for security related purposes.
The OAuth 2.0 Authorization Framework [RFC6749] provides a method for
making authenticated HTTP requests to a resource using an access
token. Access tokens are issued to third-party clients by an
authorization server (AS) with the (sometimes implicit) approval of
