This enables users of AndroidKeyStore crypto to differentiate between the key being unusable until the user is authenticated (UserNotAuthenticatedException) and the key being permanently unusable (KeyPermanentlyInvalidatedException). The latter is the case when the secure lock screen has been disabled or reset, and, for keys that require user authentication for every use, when a new fingerprint is enrolled or all fingerprints are unenrolled. NOTE: The KeyPermanentlyInvalidatedException subsumes/replaces the NewFingerprintEnrolledException which has thus been removed. There is no way to find out whether a key was permenently invalidated specifically because a new fingerprint was added. Bug: 20642549 Bug: 20526234 Change-Id: I0206cd99eef5c605c9c4d6afc5eea02eb3b1fe6b
