Bringing authentication and identification to Workers through Mutual TLS
Nov 16, 2022Dina Kozlov
Summary
Introduces the upcoming capability for Cloudflare Workers to use mutual TLS (mTLS) for outbound requests. This allows Workers to present client certificates, enabling server-side authentication and identification of the originating Worker. This addresses limitations of existing methods like Authenticated Origin Pull and token authentication by providing per-Worker granularity, secure HTTP communication, and client identity exposure.
