Abstract: In 2023, WhatsApp announced its deployment of key transparency, a feature which aims to decrease the trust placed on a centralized server when distributing public keys used for end-to-end encrypted messaging. Similar deployments have been announced for Apple iMessage and ProtonMail.This talk discusses the integration between WhatsApp and Cloudflare to audit the key transparency data structure within a live environment.
