In this episode, Dr. Daniel Fett, expert cryptographer, returns to the show to discuss the landscape of privacy-preserving measures (such as selective disclosure, zero-knowledge proofs or ZKP, etc.) that are emerging to augment existing technologies and enable new scenarios. The discussion gets very concrete when Daniel describes selective disclosure JWT, or SD-JWT, a new IETF specification he is coauthoring that offers a simple and easy-to-adopt approach to produce JWTs capable of supporting selective disclosure. Here at Identity, Unlocked, we are huge fans of this new specification, and we hope this episode will help you get started!

In this episode, Prateek, Paul, and Joni bring us back to a time in which single sign-on across domains on the web was a brand new problem. With the confidence (and the passion!) of the people who were there and made things happen, the guests take Vittorio and the listeners on a whirlwind tour touching on the technical and political challenges they had to overcome to bring SAML to life and make it the ubiquitous success it is today. From the basics of how the SAML protocol works to the entities and standard bodies that developed it, the discussion eventually reaches modern times and concludes on how in a world where old and new standards coexist, OpenID Connect picked up the innovation torch from SAML.
