This is a Golang implementation of the OpenConnect VPN Protocol for client side development.

For desktop OS, similar to Cisco Secure Client's vpnagentd, it 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. Anyone can use any front-end tool to implement their own GUI.

There is an example showing how to use this project.

Currently the following servers are supported,

• ocserv
• anylink

You can use any WebSocket tool to test the API.
