Learn the 3 Easy Steps to Encrypt App Preferences, NSUserDefaults in iOS apps – no code or coding required.
What Are App Preferences (NSUserDefaults) in iOS apps?
In iOS app development, NSUserDefaults is an interface to the user’s defaults database, which allows an app to customize its behavior to match a user’s preferences. For example, you can allow users to specify their preferred units of measurement or media playback speed. Apps store these preferences by assigning key-value pairs to a set of parameters in a user’s defaults database, which maintain persistence across app launches.
Why Encrypt App Preferences in iOS apps?
Preferences can be any kind of text-based data which may include information about users that is highly personal, private or sensitive. For example, app preferences can be used to display a screen that contains a user’s preferred currency or type of credit card used to process transactions in an e-commerce app. The use of app preferences is very broad and flexible, and there’s no restriction on the type of information that can be stored in preferences and retrieved by other resources. Furthermore, App Preferences are stored as plain-text data (unencrypted) by default, which makes them a valuable area for hackers to target with ease. For this reason, it makes sense to Encrypt App Preferences iOS apps, so that this data cannot be easily accessed by attackers.
