Data Protection on iOS

Question

If targetting iOS 4, you can use the Data Protection APIs.

If you have 'Full' protection, does this encrypt the entire sandbox?

Specifically, If I downloaded say a .doc file to disk programatically will this be encrypted? Or is it only encrypted if I use the NSData data protection options?

Answer 1

It's only encrypted if you use data protection. See App States and Multitasking, and Protecting Data Using On-Disk Encryption.
