Use an implementation of SqlCipher. It's not provided by Apple and I'm not sure there are any free pre-built versions available, so you either have to pay for a version or port it yourself (which is certainly feasible but non-trivial). – Hot Licks Jul 03 '14 at 16:03

(I don't think the "duplicate" is, though there probably are other more appropriate duplicates that could be referenced.) – Hot Licks Jul 03 '14 at 16:08

[This page](http://sqlcipher.net/ios-tutorial) appears to tell you how to build SqlCipher for iOS. I've not reviewed it, though. (I actually couldn't find any reasonable "duplicates" in a brief search.) – Hot Licks Jul 03 '14 at 16:15

If you want a password-protected file you must use SqlCiper or some other such package. Yes, you can use Apple's built-in file encryption, but with that you have to decrypt the entire file when the app starts, then re-encrypt when the app ends -- neither convenient nor secure. – Hot Licks Jul 09 '14 at 11:33
