In the keys section I've found formats for cws of various programms from canal digitaal for vantage&clones. But I've not found those for ned 2, ned 3, een and canvas.
Where can i find them?
now hopefully you will understand that CWs are no way of opening a channel for long periods which is what you are seeking, only way is to wait untill keys are available, or get official card or card sharing.
