Team,
I have an Android application with large SQLite database this data costs me lots of money and I don’t want to let anybody have it easily.
This database come to me as databse.sqlite file and I shipped into into the APK assets.
is there anyway to encrypt this database before shipping and then decrypt while reading the data ?
P.S I searched for this a lot and all of my results point me to use sqlcipher but this lib does not work with shipped SQLite database file.
The problem is that you will need to store the key (or location of the key) somewhere in your code and deodexing the application doesn’t take that much effort. Unfortunately, you can’t really prevent anyone from accessing the data. You can only make it harder, but it will still be pretty easy for someon who is really determined.
The best solution would be to store the database on a server and only send the data the user actually needs to the device. That way you have at least some control over what data a device requests.
