novnc/noVNC
NoVNC
noVNC is an HTML5 remote desktop viewer and VNC web client that allows users to access and control remote desktops, virtual machines, and containers through a web browser. It functions as a remote desktop management tool that integrates the VNC protocol to enable remote server administration without the need for a dedicated client application.
The project includes a VNC WebSocket proxy that translates binary VNC network traffic into WebSockets to bypass browser restrictions on direct TCP connections. This proxy service supports bridging connections to multiple remote servers by listening on various ports.
The system covers a wide range of remote access capabilities, including remote desktop rendering with display scaling, event-based input mapping, and bidirectional Unicode clipboard synchronization. It also provides touch gesture emulation for cross-device access on mobile devices and tablets, and secures remote sessions using authentication protocols such as RSA-AES, VeNCrypt, and Diffie-Hellman.
