Encrypt & Decrypt Sqlite file (Using Core Data)

Question

I am using a Pre-Populated SQLite Database with Core Data.

My problem is that i want to encrypt sqlite database file generated by Core Data. I cannot encrypt data because there are lots of queries involved in project. So, only i want to encrypt file.

I have already gone through lots of forum, source code, libraries but couldn't figure out much.

I have already used libraries provided by this iphone blog as well but that libraries are buggy.

If you have some core solution then please help.

Thanks, Tariq

Apple includes support for its CommonCrypto library in iOS, and has a sample code project to demonstrate use of asymmetric and symmetric encryption/decryption.

Which approach you take depends on how you intend to secure the data; a symmetric approach could require storing the key in the application, which reduces security somewhat. But the sample code should get you started, either way.
