What is Shadowsocks?
Advanced Proxy Protocol
Shadowsocks is a secure socks5 proxy designed to bypass internet censorship and provide secure tunneling for internet traffic. Created by clowwindy, Shadowsocks focuses on providing a lightweight, fast, and secure proxy solution that can evade deep packet inspection and traffic shaping.
Unlike traditional VPNs, Shadowsocks operates at the application layer, making it more flexible and easier to deploy across various platforms while maintaining strong security through modern encryption protocols.
