Learn about the current state of post-quantum cryptography implementation in a 29-minute technical talk that explores why signature algorithms are not keeping pace with key agreement protocols in browser deployment. Discover the latest developments in the post-quantum ecosystem, including NIST's recently finalized algorithms, and examine the specific challenges facing the migration to post-quantum certificates in the WebPKI. Delve into practical solutions and ongoing initiatives aimed at making post-quantum signatures viable for widespread use, followed by an in-depth breakout session discussing promising approaches to handling post-quantum certificates. Presented by Cloudflare Research Engineer Luke Valenta through the PKI Consortium.
