What is V2Ray VLESS?

V2Ray VLess (short for "V2Ray Virtual Less Protocol") is a custom protocol developed by the V2Ray project for use with the V2Ray network protocol. It is designed to provide enhanced security and anonymity for internet traffic transmitted through a V2Ray connection.

VLess is based on the MessagePack serialization format, and uses a combination of encryption and obfuscation to conceal the identity and content of the traffic being transmitted. It is designed to be efficient and fast, and is able to adapt to different network environments and censorship situations.

One key feature of VLess is its ability to support multiple encoding methods, including AES-128-GCM, ChaCha20-Poly1305, and none (plaintext). This allows users to choose the encoding method that best suits their needs and preferences.

VLess is not the default protocol used by V2Ray, but it can be used as an alternative to the VMess protocol in certain circumstances or for specific purposes. For example, VLess may be used in environments where the VMess protocol is blocked or detected by censors.

Overall, V2Ray VLess is a useful protocol for users of the V2Ray network protocol who need additional security and anonymity, and is particularly useful in environments where the VMess protocol is blocked or detected by censors.
