[Desktop] Using open source VPN clients, natively for Windows

[shamun]

1/ Getting 100% complete browser independency on privacy.

2/ How to have the Brave browser a default built-in VPN clients as following. So that we connect use our own private key to login to our own VPN servers to get ourselves disconnected from internet and live in own intranet?

Open Source VPN: https://www.wireguard.com/
OpenVPN client: https://openvpn.net/client-connect-vpn-for-windows/

3/ Example use:

; Launch the browser in full VPN and use the private key from local disk path
C:\>brave.exe --vpn-auto-connect private.key --kiosk

; Launch the browser in full VPN and use the private key from pre-defined web path with password / username 
C:\>brave.exe --vpn-auto-connect https://username:password@www.mysite.com/private.key --kiosk

If we implement that, we could look at supporting custom configs in the browser (ex: Bring Your Own VPN)
