iOS: Get iPhone passcode to generate symmetric keys for encryption

Question

I\'m developing an iOS app that is distributed to devices that are all locked with a passcode. Is there a way to get the device passcode (or some form of it) to dynamically gene

Answer 1

No. There is no API to determine if there is a device passcode set or to get the passcode if one is set.

You will need to generate the keys using some other value. One option would be to require the user to enter an app specific passcode.
