shadowsocks/shadowsocks-libev

Features

• SOCKS5 Proxies - Implements an encrypted proxy server that uses the SOCKS5 protocol to route TCP and UDP traffic.
• Shadowsocks Tunnel Implementations - Implements the Shadowsocks protocol to encrypt and tunnel TCP and UDP traffic through a SOCKS5 proxy.
• Event-Driven Networking - Functions as a high-performance network daemon using an event-driven model for concurrent connections.
• UDP Tunneling - Provides encapsulation and redirection of UDP traffic through encrypted proxy connections.
• Non-Blocking Socket I/O - Uses asynchronous non-blocking socket I/O to handle high concurrency without thread-per-connection overhead.
• TCP Tunneling - Implements wrapping of TCP streams in custom encrypted protocols to bypass network restrictions.
• Traffic Encryption - Encrypts internet traffic in transit using specific ciphers to bypass network censorship.
• Configurable Cipher Encryptors - Provides configurable cipher methods to encrypt network traffic and bypass network restrictions.
• Non-Blocking Event Loops - Employs a non-blocking event loop architecture via libev to manage concurrent network operations.
• Local Port Mapping - Maps local ports to specific destination server addresses to tunnel traffic to remote targets.
• UDP-over-TCP Encapsulations - Wraps UDP datagrams inside TCP streams to ensure reliable delivery when native UDP is blocked.
• Transparent Network Proxies - Functions as a network-layer interceptor that redirects system traffic transparently through an encrypted tunnel.
• Transparent Proxies - Intercepts network traffic at the system layer to route it through the proxy without client configuration.
• Transparent Proxying - Intercepts and redirects outbound network traffic through the proxy without requiring client-side configuration.
• Session Multiplexers - Multiplexes multiple TCP and UDP proxy sessions over a single encrypted tunnel using a shared cipher context.
