 When providing integrity on the storage itself, you can either create an HMAC over a given key-value pair (as for the Android `SharedPreferences`) or create an HMAC over a complete file that's provided by the file system.

 When ensuring the integrity of the application storage itself, you can create an HMAC or signature over either a given key-value pair or a file stored on the device. The CommonCrypto implementation is best for creating an HMAC.
