supplicant-rs

Pure Rust WPA supplicant. Memory-safe replacement for wpa_supplicant.

WPA2/WPA3, EAP-TLS, 802.1X — no C, no unsafe, no CVEs.

Features

  • WPA2 — 4-way handshake, PMKSA caching
  • WPA3-SAE — Simultaneous Authentication of Equals (dragonfly)
  • EAP — EAP-TLS (via rustls), EAP-TTLS, EAP-PEAP
  • 802.1X — EAPOL state machine
  • PMF — Protected Management Frames
  • nl80211 — Linux kernel Wi-Fi interface via netlink

Why?

wpa_supplicant is ~500K lines of C running as root on every Linux device with Wi-Fi. It parses complex (and often malicious) protocol frames. Memory corruption vulnerabilities like KRACK (CVE-2017-13077) affect billions of devices.

supplicant-rs is a ground-up Rust rewrite. Memory-safe by construction. No unsafe in protocol handling.

Status

Early development. Not functional yet. Seeking Prossimo/ISRG funding for full implementation.
