sslcon

This is a Golang implementation of the OpenConnect VPN Protocol 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 is a GUI client example showing how to use this project.

Currently the following servers are supported,

• AnyLink
• OpenConnect VPN server

除非有不得不用的理由，建议远离 Electron

安装包体积不是问题，关键是它会在硬盘 cache 目录拉一坨，一坨还好，那一坨又一坨呢？
