NIST has finalized the first set of post-quantum algorithms, and post-quantum key agreement has been enabled by default in browsers for over a year. Why are signatures lagging behind? This talk provides the latest updates in a fast-moving ecosystem, a recap of the challenges in migrating to post-quantum certificates, and an overview of ongoing efforts to make post-quantum signatures practical in the WebPKI.
In a followup breakout session, we go into detail into some of the more promising proposals for coping with post-quantum certificates.
