Hi together,
i wrote a short script which uses a .ovpn config and creates accordingly a NetworkManager VPN Profile.
As Kali comes shipped with NetworkManager maybe someone can utilize it:
It will create a profile called “HackTheBox USERNAME”
It extracts all the keys and certificates from the ovpn config and places them in ~/.htbvpn
Afterwards you can run and manage the VPN connection by left clicking the NetworkManager plugin in Kali
