# HevSocks5Core
HevSocks5Core is a simple, lightweight socks5 library.
**Features**
* IPv4/IPv6. (dual stack)
* Standard `CONNECT` command.
* Standard `UDP ASSOCIATE` command.
* Extended `FWD UDP` command. (UDP in TCP)
* Multiple username/password authentication.
**Dependencies**
* HevTaskSystem - https://github.com/heiher/hev-task-system
