Shadowsocks

Shadowsocks is an open-source proxy software originally created by a Chinese programmer named "clowwindy". It is designed to break through China's Internet censorship. Here's how Shadowsocks works:

• Proxy mechanism: Shadowsocks uses the Socks5 proxy protocol to encrypt the user's Internet traffic and send it through a relay server. The relay server can be located anywhere, thus bypassing geographical restrictions and Internet censorship.
• Encryption: Shadowsocks uses a variety of encryption algorithms (such as AES, Chacha20) to protect the user's traffic from being monitored or tampered with.
• Distributed network: Users can build their own Shadowsocks servers, or use public Shadowsocks servers.
