JWTs done right: Quebec's proof of vaccination

Read Original

The article provides a technical deep-dive into Quebec's implementation of a proof-of-vaccination system using JWTs (JSON Web Tokens) and QR codes. The author, expecting privacy flaws, analyzes the encoded data structure, explores the security approach, and discusses the zero-knowledge aspects of the design, concluding it was implemented reasonably well.
