RFC 9068: A JWT-Based OAuth2 Access Token Format Standard
For anyone who has been paying attention, this blog post has been a long-time coming for multiple reasons. First, this is my first blog post in a couple of years — I’ve been heads down on a couple of projects for awhile now. This is literally the first time I’ve “come up for air” since the last…
Delegation — A General Discussion
This blog post expands on delegation and related concepts introduced in my Kerberos Delegation blog post. It also brings together two blog series I’ve been working on over the years: SAML2 vs. JWT Series and Kerberos and Windows Security Series. Delegation is a critical building block of end-to-end…
SAML2 vs JWT: A Comparison
This post concludes our discussion of SAML2 and JWT. Here we look at a comparison of the features and use cases of the two technologies. It’s difficult to make a direct comparison of JWT and SAML2. As we’ve seen through this series, one must take into account the specifications that work in…
JWT Use Cases
This post explores the equivalent JWT use cases corresponding to the five SAML2 use cases that were explored earlier in this series. We had to build up our tool set to get to this point — including exploring JWT, OAuth2, OpenID Connect, and the supporting specs. To be ready for this moment, we’ve…
SAML2 Use Cases
The following blog posts discuss SAML2 use cases that have been explored in this series:
Understanding OpenID Connect Series
The following blog posts make up my series on OpenID Connect. This is part of the SAML2 vs JWT series.
SAML2 vs JWT: Understanding OpenID Connect Part 3
In part 1 and part 2 of Understanding OpenID Connect, core concepts and the first Authentication Flow (Authorization Code Grant Flow) were introduced. In part 3, we look at the remaining Authentication Flows (Implicit Flow and Hybrid Flow) and some other features of the OIDC specification.
SAML2 vs JWT: Understanding OpenID Connect Part 2
This post continues our discussion of OpenID Connect (OIDC). We look at one of the three Authentication Flows defined by the OIDC spec — the Authorization Code Grant Flow.
SAML2 vs JWT: Understanding OpenID Connect Part 1
This post builds upon what we learned about OAuth2 and JWT in previous posts. OpenID Connect will give us the final building block for the JWT-related use cases that this series will explore. The goal of this blog post is to provide a deep understanding of the OpenID Connect spec without having to…
SAML2 vs JWT: Understanding OAuth2
This blog post continues the SAML2 vs JWT series. In the last post, we discussed JSON Web Tokens. Now, we are going to move on to OAuth2 and OpenID Connect, which provides some structure and protocol around the use of JWT. These protocols are used, along with JWT, to build the JWT use cases this…
SAML2 vs JWT: Apigee & Azure Active Directory Integration — A JWT Story
In our next SAML2 vs JWT post, we are going to use a JWT with a very simple API that is proxied through Apigee Edge Public Cloud. The JWT token will be an OAuth2 access token generated by Azure Active Directory. In the last post in this series, we explored what JSON Web Tokens (JWTs) are and the…
SAML2 vs JWT: Understanding JSON Web Token (JWT)
In this post, we begin our exploration of the JSON Web Token (JWT) specification as part of the SAML v2.0 vs JWT Series. To understand JWT use cases, we must also look at OpenID Connect v1.0, OAuth v2.0, and and a few related specifications — the JWT spec by itself is not very interesting or…
