The OAuth Assertions specs are now RFCs!

OAuth logoThe OAuth Assertions specifications are now standards – IETF RFCs. They are:

  • RFC 7521: Assertion Framework for OAuth 2.0 Client Authentication and Authorization Grants
  • RFC 7522: Security Assertion Markup Language (SAML) 2.0 Profile for OAuth 2.0 Client Authentication and Authorization Grants
  • RFC 7523: JSON Web Token (JWT) Profile for OAuth 2.0 Client Authentication and Authorization Grants

This completes the nearly 5 year journey to create standards for using security tokens as OAuth 2.0 authorization grants and for OAuth 2.0 client authentication. Like the JWT and JOSE specs that are now also RFCs, these specifications have been in widespread use for a number of years, enabling claims-based use of OAuth 2.0. My personal thanks to Brian Campbell and Chuck Mortimore for getting the ball rolling on this and seeing it through to completion, to Yaron Goland for helping us generalize what started as a SAML-only authorization-grant-only spec to a framework also supporting client authentication and JWTs, and to the OAuth working group members, chairs, area directors, and IETF members who contributed to these useful specifications.
