Data Protection / NSFileProtectionComplete - successfully supported through entitlements.plist?

Question

I\'m looking to encrypt user data in an app, and the NSFileProtection mechanism looks perfect for this.

This SO Question / Answer thread pointed me at the WWDC 2011

Answer 1

It wouldn't work for me using the wildcard for the profile id (i.e. my.company.app.*) so had to create a new fully qualified one. It works for me with my Entitlements.plist looking like this:

    com.apple.developer.default-data-protection
    NSFileProtectionComplete
    get-task-allow
    

and with my profile section for it looking like this: ....

    application-identifier
    xxx.my.company.app
    com.apple.developer.default-data-protection
    NSFileProtectionComplete
    get-task-allow
    
    keychain-access-groups
    
        xxxxxxxx
