V2Ray

V2Ray is an open-source protocol part of the Project V platform, designed to enhance privacy and bypass censorship. It supports multiple tunneling protocols like VMess, Shadowsocks, SOCKS, and HTTP. Its modular design allows flexible configurations to adapt to various internet censorship scenarios.^[1]^[2]^[3]^[4]

Specifications

VMess is V2Ray's primary protocol, uses strong encryption and dynamic port allocation to resist DPI-based detection. V2Ray can obfuscate traffic to mimic HTTPS or WebSocket and adjusts to changing network conditions, making it effective in censorship-heavy environments such as China.^[1]^[2]^[5]
