If you Google “iphone data protection apis” you’ll see a zillion hits based on press releases.
If you check out http://support.apple.com/kb/HT4175 you can see Apple making the indication directly.
Where are/what are these APIs? I’ve used the old crypto APIs before iOS4, so they’re not those.
These APIs are supposed to give MDM (Mobile Device Management)-type capability for 3rd-party apps.
TIA!
There are some
FileProtectionoptions you can set when writing anNSDatato disk:NSDataWritingFileProtectionCompleteNSDataWritingFileProtectionNone)as well as an extended attribute,
NSFileProtectionKey, you can set on pre-existing files on disk viaNSFileManager:NSFileProtectionCompleteNSFileProtectionNoneThe app delegate is also informed of when your application is (not) going to be able to access protected data:
-applicationProtectedDataDidBecomeAvailable:-applicationProtectedDataWillBecomeUnavailable:All the gory details of encrypting and securing the data are handled by the hardware and OS on your behalf. It’s fire-and-forget protection that kicks in whenever the device locks.
