Single class that handles encryption and decryption with keys using the Android `Keystore` API. Mostly inspired by this [blog post](https://medium.com/@ericfu/securely-storing-secrets-in-an-android-application-501f030ae5a3). This was tested with API 18 and 25 level emulator (and a level 23 device).
