VPN, the abbreviation for Virtual Private Network, secures communication between two or more devices by establishing private tunnels over public networks and encrypting data transferred inside them.

A VPN connection provides an array of benefits: through encryption, data become indecipherable; through tunneling, online activities reveal little more than a VPN session; through forwarding, traffic appear to originate from a IP address and location.

ShadowSocks (SS) is an encrypted stateless proxy protocol. It works at transmission layer and relays both TCP and UDP traffic. It is designed to penetrate China's highly sophisticated national firewall – known as the GFW.

ShadowSocksR (SSR) is a major fork of SS. Building upon SS, SSR patches up security vulnerabilities, expands supported cipher suite, adds in obfuscation, and improves QoS priority at carrier level.
