How to Encrypt App Contants & Strings in iOS Apps
Learn to Prevent Data Breaches in iOS apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.
What are Data Breaches?
Using Appdome’s Strings and Resources Encryption you can easily encrypt all strings (such as CFStrings) in iOS apps. This feature greatly enhances the security of the app against malicious attempts to read the app’s contents or harvest valuable data about mobile users.
Appdome is a no-code mobile app security platform designed to add security features, like strings and resource encryption to Android and iOS apps 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 protect sensitive data in iOS apps.
Why Prevent Data Breaches in iOS Apps?
Why do we need to encrypt App Constants & Strings in iOS Apps?
The soft belly of any application is the thing that can be easily understood from the application without using specialized tools. The top two in the list are:
- Strings: Human-readable words, phrases, URLs, tokens, passwords etc…
- Resources: Images, audio, video, and anything that’s easy to double-click on a PC.
Anyone can unpack a .ipa file, and snoop around, which those files above mentioned can be opened or read (images, movies, audio snippets and the occasional plist or db file).
Prerequisites for Using Encrypt Strings and Resources:
To use Appdome’s mobile app security build system to Prevent Data Breaches , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Encrypt Strings and Resources
- Mobile App (.ipa for iOS)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
Prevent Data Breaches on iOS apps using Appdome
On Appdome, follow these 3 simple steps to create self-defending iOS Apps that Prevent Data Breaches without an SDK or gateway:
-
Upload the Mobile App to Appdome.
-
Upload an app to Appdome’s Mobile App Security Build System
-
Upload Method: Appdome Console or DEV-API
-
iOS Formats: .ipa
-
Encrypt Strings and Resources Compatible With: Obj-C, C+, Java, Swift, Flutter, React Native, Unity, Xamarin, Cordova and more
-
-
Build the feature: Encrypt Strings and Resources.
-
Building Encrypt Strings and Resources by using Appdome’s DEV-API:
-
Create and name the Fusion Set (security template) that will contain the Encrypt Strings and Resources feature as shown below:
-
Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Encrypt Strings and Resources feature via Appdome Console, to add the Encrypt Strings and Resources feature to this Fusion Set.
-
Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set, as shown in Figure 1 above, and get the Fusion Set ID from the Fusion Set Detail Summary (as shown below):
Figure 2: Fusion Set Detail Summary
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory). -
Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, App Center, Jenkins, Travis, Team City, Cirlce CI or other system:
-
Build an API for the app – for instructions, see the tasks under Appdome API Reference Guide
-
Look for sample APIs in Appdome’s GitHub Repository
-

Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required). -
-
Building the Encrypt Strings and Resources feature via Appdome Console
To build the Encrypt Strings and Resources protection by using Appdome Console, follow the instructions below.
-
Where: Inside the Appdome Console, go to Build > Security Tab > TOTALData™ Encryption section.
-
When you select the Encrypt Strings and Resources you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Encrypt Strings and Resources

-
Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
-
Congratulations! The Encrypt Strings and Resources protection is now added to the mobile app -
Using Appdome, there are no development or coding prerequisites to build secured iOS Apps by using Encrypt Strings and Resources. There is no SDK and no library to code or implement in the app and no gateway to deploy in your network. All protections are built into each app and the resulting app is self-defending and self-protecting.
Releasing and Publishing Mobile Apps with Encrypt Strings and Resources
After successfully securing your app by using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
- Customizing, Configuring & Branding Secure Mobile Apps
- Deploying/Publishing Secure mobile apps to Public or Private app stores
- Releasing Secured Android & iOS Apps built on Appdome.
