We touched on cryptography very brie fly in Chapter 4. This chapter will focus more on the importance of using cryptography to obfuscate and secure user data that you will either store or transport. First, we will cover the basics of cryptography and how they apply to us in the context of application development. Next, we will look at the various mechanisms of storing data on the Android platform. Along the way, I will give examples of how to store and retrieve data from different mechanisms and outline what function each store is ideally suited to perform.
