Security of the persistent store
BlackBerry Device Software provides two main ways to secure objects in the persistent store:
- Restrict access to the objects with the net.rim.device.api.system.ControlledAccess class and code signing keys.
- Encrypt and decrypt objects with the net.rim.device.api.system.PersistentContent class.
Depending on the needs of your app, you can use both, one, or neither of these approaches.
