VMess

VMess is an encrypted transmission protocol used in the V2Ray project to achieve secure communication between clients and servers. V2Ray is a powerful network proxy tool that supports multiple protocols and advanced features, and VMess is one of the most commonly used protocols.

Features of VMess

• Encryption: The VMess protocol uses multiple encryption methods to protect transmitted data and prevent data from being monitored or tampered with. Common encryption methods include AES, ChaCha20, etc.
• Authentication: VMess includes a two-way authentication mechanism for clients and servers to ensure that only authenticated clients can connect to the server, thereby preventing unauthorized access.
• Obfuscation: In order to prevent traffic from being detected and identified, VMess supports multiple traffic obfuscation methods, making its traffic look like ordinary HTTPS or other types of traffic.
• Multi-protocol support: VMess can be used in conjunction with a variety of transport protocols, including TCP, mKCP, WebSocket, HTTP/2, QUIC, etc., which enhances flexibility and concealment.

How VMess works

• Client configuration: The user configures the V2Ray client locally and specifies the address, port, UUID (user ID), encryption method, and other information of the VMess server to be connected.
• Server configuration: Configure V2Ray on the remote server and set the VMess protocol and related parameters, including the client UUID allowed to connect.
• Connection establishment: The client initiates a connection request, and the server establishes an encrypted channel by verifying the client's UUID and other information.
• Data transmission: Once the connection is established, all data transmission between the client and the server is carried out through an encrypted channel to ensure security and privacy.

Relationship with Clash for Windows

Clash for Windows is a graphical user interface (GUI) client that can support and manage multiple network proxy protocols, including VMess. With Clash for Windows, users can easily configure and use VMess nodes and combine them with other rules and proxy types for flexible traffic management.
