Yes RP, The key files feature is discontinued in version 2. It may come back in a different form using hardware tokens as carrier of a full strength key, but for now we do not support it in version 2. It was seldom used, and the added security is very small compared to a good and strong password in the sense that you can’t reasonable break either. If it takes 100 years to crack a single strong password used with AxCrypt, there’s not much benefit in a full strength key – even if the time then is more like perhaps several 1000 years or a million years or whatever. A good strong password is strong enough for most situations, and the key file feature has confused more users than it has been used.
