## README



## sslcon

This is a Golang implementation of the [OpenConnect VPN Protocol](https://datatracker.ietf.org/doc/html/draft-mavrogiannopoulos-openconnect-04) for client side development. 

The released binaries contain a command line program(sslcon) and a VPN service agent(vpnagent), the latter of which should be run as a separate background service with root privileges, so that the front-end UI does not require an administrator authorization every time it starts. 

The API is exposed through the WebSocket and JSON-RPC 2.0 protocols, so developers can easily customize a graphical interface that meets their needs.

**[There](https://github.com/tlslink/anylink-client) is a GUI client example showing how to use this project.**

Currently the following servers are supported,

- [AnyLink](https://github.com/bjdgyc/anylink)
- [OpenConnect VPN server](https://gitlab.com/openconnect/ocserv)
