olcRTC

olcRTC (OpenLibreCommunity RTC) is an encrypted TCP-over-WebRTC tunnel. Traffic is disguised as an ordinary video call on allowed services (Jitsi, Yandex Telemost, WbStream). Inside there is XChaCha20-Poly1305 encryption and smux multiplexing over WebRTC data/video channels.

Status: Beta

app -> SOCKS5 -> olcrtc cnc -> WebRTC/SFU service -> olcrtc srv -> internet

Important: make sure the video call service you need is on the allow lists and works in your network. If not, use another one.

Features

• Providers: jitsi, telemost, wbstream
• Transports: datachannel, vp8channel, seichannel, videochannel
• Platforms: Linux, macOS, Windows, Android (gomobile), embeddable Go library

Recommended start: jitsi + datachannel.
