​ What is uPKI?

While web browsers automatically check if an HTTPS certificate has been revoked, other Linux command-line tools and applications usually skip this check. That leaves applications vulnerable to compromised or misissued certificates many months after this is discovered. In their talk, Joe Birr-Pixton and Dirkjan Ochtman will be introducing uPKI: a new effort to bring browser-grade certificate infrastructure to Linux. This effort is funded by Canonical, engineered by the maintainers of rustls, and builds on foundational work from Mozilla.

About Dirkjan
Dirkjan Ochtman is a professional Rust maintainer, active on projects like rustls, Hickory DNS and Quinn. He lives in the Netherlands with his family.

About Joe

These days, Joe mostly works in Rust, but his professional experience is in C and C++. He is the original author of the “rustls” crate, which provides TLS support to most of the Rust ecosystem.
