GoKawiilDeveloper open-sources RawLink, a Rust-based encrypted VPN tunnel protocol
A developer has released RawLink, an open-source tool written in Rust that creates an encrypted TCP tunnel using AES-256-GCM. It routes traffic from a local SOCKS5 proxy through the tunnel to a remote server, supports multiple simultaneous streams and tunnels, and offers optional obfuscation and SSH traffic mimicry to disguise connections. The author notes the code was written with AI assistance and has not yet undergone a formal security audit.
GoKawiil's interpretation of the reporting above, not reported fact.
Releasing it as open source invites community scrutiny, which could help surface vulnerabilities before wider adoption, but the author's own caution about a missing security audit means early users take on real risk if they deploy it for sensitive traffic. The obfuscation and traffic-mimicry features suggest the tool is aimed partly at evading network censorship or detection, a use case that could attract both privacy-focused users and regulatory attention.
- RawLink is a new open-source encrypted tunnel protocol built in Rust using AES-256-GCM.
- It supports multiplexed streams, multiple tunnels, auto-reconnect, and optional traffic obfuscation or SSH mimicry.
- The developer warns the AI-assisted code has not yet had a thorough independent security audit.
