How to Encrypt Plists (property lists) in iOS apps

 

Learn the 3 easy steps to Encrypt Plists in iOS apps to protect information about the app bundle, its contents and how the app is packaged and configured.

What is a Plist (property list)?

In iOS apps, a plist (aka ‘property list’) is a structured text file that contains metadata about the app which are essential for the app to run. Plists are collections of key-value pairs (such as a dictionary list) that specify how the system should interpret the associated bundle. Some key-value pairs characterize the bundle itself, while others configure the app, framework, or other entity that the bundle represents. Some keys are required, while others are specific to particular features of the executable.

iOS apps can have multiple plists for specific functions, and the details of what to include in the property list vary by executable type and by platform. However, all iOS apps must have the at least one plist (info.plist is the default property list supplied by Xcode when you create a project)

Appdome is a no-code mobile app security platform designed to add security features, like Encrypt Plist to any iOS app without coding. This KB shows mobile developers, DevSec and security professionals how to use Appdome’s simple ‘click to build’ user interface to quickly and easily encrypt properties lists in iOs apps.

3 Easy Steps to Encrypt Plists in iOS apps

Please follow these 3 easy steps to Encrypt Plists in iOS apps using Appdome.

Congratulations! The app is now protected with Plist encryption.

 

Appdome’s no-code mobile app security platform offers mobile developers, DevSec and security professionals a convenient and reliable way to protect Android and iOS apps with Plist encryption. When a user clicks “Build My App,” Appdome leverages a microservice architecture filled with 1000s of security plugins, and an adaptive code generation engine that matches the correct required plugins to the development environment, frameworks, and methods in each app.

Additional Information About Plist Encryption

Every app and plug-in uses info.plist to store data so the system can easily access it. The following key types cannot be encrypted because they need to be accessible to both the OS and the application:

  • Core Foundation Keys (start with CF prefix),
  • Cocoa Keys (start with NS prefix),
  • iOS Keys (start with UI prefix),
  • DT Xocde keys (start with DT prefix),

When you submit the secured app to Apple’s App Store, the above keys should be left unencrypted either because they are core foundation keys, define the target platform for the app (iOS, watchOS, etc.), used to configure the appearance of your app at launch and runtime or are added by Apple via Xcode.

Prerequisites

No Coding Dependency

Using Appdome, there are no development or coding prerequisites to build secured iOS apps with plist encryption. There is no SDK and no library to manually code or implement in the app. The Appdome technology adds the relevant standards, frameworks, and logic to the app automatically, with no manual development work at all.

How to Sign & Publish Secured Apps

After successfully securing your app using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
