I am developing an android app that uses the safe_app_java. So far all of the time keys that I use are either predefined constants or just a int sequence, i.e. there is nothing to “hide” that needs to be encrypted. At the same time in the examples keys are encrypted.
What are the potential use cases where the keys need encryption? As far as I can image the keys should be just a unique identifier and not contain sensitive data (if the system is designed properly).
