Just checking how this affects US export regulations.</p> I used NSValueTransformer to do encryption/decryption using Apples CommonCryptor Toolbox(AES128) so far.

What about if you ship valuable data with your app. I guess you have to encrypt table content in your sqlite database and use a built-in decryption engine?! I'm always using core data so there is no way to use SQLCipher (http://www.zetetic.net/code/sqlcipher). As far as I understand relies the built-in hardware encryption from Apple on the fact, that the user uses a passcode!</p> I’ve just also read the article from Nick als well as the notes from Anthony http://anthonyvance.com/blog/forensics/ios4_data_protection/ but it answers only the question how to protect data generated on the device itself.
