Hi All,
I'm interested in avoiding simple predicate tricks like played on
OneSafe at https://viaforensics.com/iphone-forensics/preventing-widespread-ios-application-infection.html.
While Zdziarski gets the secrets in OnePass, I'm more concerned with
leaking filenames. The files themselves are using Authenticated
Encryption (EtA variety), and I can keep a bad guy out with the
authentication tag.
Is it possible to encrypt a NIB or StoryBoard?
I believe I can decrypt a NIB on the fly with initWithNibFile and a
key derived from a password. But I'm not clear how to encrypt the NIB
before it goes into an IPA or App Bundle.
I'm also not clear what to do with Storyboards. I suspect the solution
for NIBs will likely apply to StoryBoards in a general sense. I have
not read any of the iOS 5.0 books yet, but its on the TODO list.
Jeff
