RawLink is a Rust-based encrypted TCP tunnel that multiplexes SOCKS5 traffic over a single connection, featuring AES-256-GCM encryption, optional traffic obfuscation (random or SSH mimicry), and auto-reconnect. It stands out by implementing a custom protocol from scratch with a clear packet format and header masking, aiming to resist censorship and detection.

Target audience: security engineers, network engineers, privacy enthusiasts
