Non-Native Code Obfuscation, Anti-Reversing for Android & iOS Frameworks
Learn to Obfuscate Non-Native Code Obfuscation in Mobile apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.
What is Non-Native Code Obfuscation?
To counter this vulnerability, Non-Native Code Obfuscation obfuscates your source code in the application itself. For instance, it ensures that Xamarin code file extensions such as .exe, .dll, .dll.config, and .blob are encrypted. For React Native applications, the .jsbundle files are encrypted, while for Cordova, the .js and .html files are encrypted. This encryption prevents unauthorized reading of your app’s contents, even if someone were to try extract the app’s files. You can easily integrate Non-Native Code Obfuscation into any Xamarin, Cordova, or React Native JS application on iOS or Android without the need for additional code or coding.
Why using Non-Native code obfuscation?
Obfuscating non-native mobile apps is a complex and time-consuming process. This process requires employing several methods and tools, and the development resources needed for completing the task are highly specialized. Appdome simplifies the challenge of obfuscating non-native mobile apps by eliminating the need for specialized tools or development resources; you only need to enable our protection.
Prerequisites to Using Non-Native Code Obfuscation:
To use Appdome’s mobile app security build system to Obfuscate Non-Native Code Obfuscation , you’ll need:
- Appdome account (create a free Appdome account here)
- A license for Non-Native Code Obfuscation
- Mobile App (.ipa For iOS device or .apk or .aab For Mobile)
- Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)
Obfuscate Non-Native Code Obfuscation on Mobile apps using Appdome
On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Obfuscate Non-Native Code Obfuscation 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
Mobile App Formats: .ipa For iOS device or .apk or .aab
Non-Native Code Obfuscation Compatible With: Obj-C, C+, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more
Build the feature: Non-Native Code Obfuscation.
Congratulations! The Non-Native Code Obfuscation protection is now added to the mobile app
Building Non-Native Code Obfuscation by using Appdome’s DEV-API:
Create and name the Fusion Set (security template) that will contain the Non-Native Code Obfuscation feature as shown below:
Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the Non-Native Code Obfuscation feature via Appdome Console, to add the Non-Native Code Obfuscation 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:

Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required).
Building the Non-Native Code Obfuscation feature via Appdome Console
To build the Non-Native Code Obfuscation protection by using Appdome Console, follow the instructions below.
Where: Inside the Appdome Console, go to Build > Security Tab > TOTALCode™ Obfuscation section
How: Toggle (turn ON) Non-Native Code Obfuscation, as shown below.
If needed, Customize the Threat Notification to be displayed to the mobile end-user in a standard OS dialog notification when Appdome Obfuscates Non-Native Code Obfuscation.
Figure 3: Obfuscate Non-Native Code Obfuscation option
Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.
When you select the Non-Native Code Obfuscation you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains Non-Native Code Obfuscation

Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
Certify the Non-Native Code Obfuscation feature in Mobile Apps.
After building Non-Native Code Obfuscation, Appdome generates a Certified Secure™ certificate to guarantee that the Non-Native Code Obfuscation protection has been added and is protecting the app. To verify that the Non-Native Code Obfuscation protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:
Figure 5: Certified Secure™ certificate
Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that Non-Native Code Obfuscation has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Non-Native Code Obfuscation and other mobile app security features are in each build of the mobile app
Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using Non-Native Code Obfuscation. 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.
