/**
 * Indicates that the key can no longer be used because it has been permanently invalidated.
 *
 * <p>This only occurs for keys which are authorized to be used only if the user has been
 * authenticated. Such keys are permanently and irreversibly invalidated once the secure lock screen
 * is disabled (i.e., reconfigured to None, Swipe or other mode which does not authenticate the
 * user) or when the secure lock screen is forcibly reset (e.g., by Device Admin). Additionally,
 * keys configured to require user authentication to take place for every of the keys, are also
 * permanently invalidated once a new fingerprint is enrolled or once no more fingerprints are
 * enrolled.
