Hi,
We are using file data protection in our App. Some files use NSFileProtectionComplete and some use NSFileProtectionCompleteUntilFirstUserAuthentication. According to our tests (we are using iExplorer), files with NSFileProtectionComplete attribute are not accessible and readable. On the other hand, files with NSFileProtectionCompleteUntilFirstUserAuthentication are readable and does not seem to be protected. Also, we had observed that App downloaded from the store are completely unreadable.
- Does the NSFileProtectionCompleteUntilFirstUserAuthentication is effective only when the App is downloaded from the store?
- Does iExplorer is the right tool to test data protection?
(XCode 7.3.1 + iOS 9.3.1 + iExplorer 3.9.9.1)
Thanks!
David
