# RJ Connect: Ruijie campus authentication protocol research

> RJ Connect documents Ruijie campus-network authentication at the packet, field, cryptographic and state-machine levels. Its Zig library implements the studied macOS 1.35 and MentoHUST 0.3.1 wired EAP-MD5 profiles, including private tail fields and session transitions. PEAP and Direct paths remain internal research modules.

## Requirements & limits

- **Prerequisites:** Use the Zig version declared in build.zig.zon; a client supplies network I/O, time, randomness and credentials.
- **Limits:** Real-network interoperability still requires integration testing; PEAP and Direct are outside the public session interface.
- **License:** MIT license.
