They're just warnings you don't need to worry about, it happens when the key files has extra keys that hactool doesn't recognise or need. So this doesn't tell you anything about the success of what you're trying to do, if it didn't work then the problem is elsewhere.if im getting these errors is it because i'm using an old version?
