Why Microsoft’s F* Language Powers Firefox, Linux Kernel, and Azure Security
F* is a proof‑oriented programming language developed by Microsoft Research, INRIA and the open‑source community that generates mathematically verified C code used in critical components such as Firefox’s TLS handshake, Linux’s WireGuard crypto, Azure packet parsing, and even blockchain smart contracts, offering zero‑day‑free security at the cost of higher proof‑writing effort.
