Overview

Package shadowsocks provides compatible functionality to Shadowsocks.

Shadowsocks client and server are implemented as outbound and inbound respectively in V2Ray's term.

Shadowsocks OTA is fully supported. By default both client and server enable OTA, but it can be optionally disabled.

Supperted Ciphers: * AES-256-CFB * AES-128-CFB * Chacha20 * Chacha20-IEFT
