VMess

VMess is a transmission protocol born inside the V2Ray project. It was engineered to resist Deep Packet Inspection: traffic rides over TCP while encryption and obfuscation obscure what is really being said, making the channel difficult to identify and block.

VMess Capabilities

• Encryption: AES-128-CFB and ChaCha20 keep the payload confidential.
• Obfuscation: Shaped traffic closely resembles ordinary HTTPS, defeating signature-based detection.
• Dynamic ports: Ports can change to stay ahead of filters.
• Cross platform: Works on Windows, macOS, Linux, Android, and iOS.
• Many transports: TCP, mKCP, WebSocket, HTTP/2 and others are supported.
