Hello,
I'm just beginning to learn Cocoa programming and I'm having some
trouble figuring out how to encrypt a persistent data store
transparently. I'm trying to write a Core Data (not document based)
application and it needs to store the data in a file encrypted with AES.
I found out about CDSA which I'm planning on using for the actual
encryption and decryption of the data but I haven't the slightest idea
how to find out what methods my subclass needs to override. I was
thinking placing the encryption between archiving the data and
actually writing it to the disk but I'm not quite sure how to do that.
Some kind of sample code would be much appreciated along with maybe
some advice/info for how to find this kind of information on my own as
I don't particularly like bothering people with simple questions on
mailing lists but I've exhausted every other resource readily
available. I've look at the NSPersistentStore,
NSPersistantStoreCoordinator class references, the Core Data
Programming Guide and the Low-Level Core Data Tutorial along with
searching the mailing lists with no luck finding what I need.
Thanks,
Chris Benedict
