Since 1.3.0 release of the library, we build on the security foundation provided by aerogear-crypto-ios[link]  to offer encrypted variants of our existing in-memory and plist based data stores (with an sqlite variant in the works).  If you have been using the existing data stores to persist your data, you will be happy to know that you easily switch to an encrypted variant by simple changing the type and some small (really!) amount of code to provide the necessary crypto params. Let's start with a small primer to symmetric encryption, which is primary cryptography mechanism used to encrypt the data stores.
