Encrypt All Code
| Plan | Platforms | MASVS |

| Enterprise | Android | MASVS-RESILIENCE-3 |
Summary
Encrypt All Code is AppTego's strongest Android static-analysis resistance control. It hardens supported application code during the protected build process so decompiled output is substantially harder to understand, copy, or modify.
Use this control for Android apps that contain valuable business logic, proprietary algorithms, fraud controls, authentication flows, licensing logic, payment logic, or security-sensitive decision paths.
What It Protects Against
- Static reverse engineering of application logic.
- Extraction of proprietary algorithms or security-sensitive code paths.
- Rapid patching of release builds by attackers.
- Automated decompiler workflows that depend on readable bytecode.
- Competitor or attacker analysis of high-value implementation details.
How It Works
During protected build creation, AppTego transforms supported application code and adds the runtime support needed for the app to execute normally. The transformation is applied after other compatible obfuscation controls so the final release artifact has a stronger static-analysis posture.
AppTego handles the hardening mechanics. Your team should focus on choosing the right protection profile, validating compatibility, and measuring startup, size, and functional impact before production release.
How to Enable the Control
Navigate to Code Obfuscation from the AppTego portal, and expand the Code And String Protection section. Under this section you will find the Encrypt All Code control. Click Enable to apply it to the next protected build.
API Configuration Example
{
"EncryptAllCode": {
"protection": true
}
}| Field | Purpose |
|---|---|
protection | Enables encrypt all code for protected builds. |
Setup
- Open the AppTego Portal.
- Select the intended configuration version.
- Open Code Obfuscation.
- Enable Encrypt All Code.
- Save the configuration.
- Build a protected Android app.
- Run functional, startup, performance, crash, and login-flow validation on physical devices.
Compatibility Guidance
| Area | What to validate |
|---|---|
| Reflection and dynamic loading | Confirm features that load classes, methods, or resources by name still work. |
| Native bridges and cross-platform frameworks | Test React Native, Flutter, Unity, Cordova, Xamarin, MAUI, and similar bridge paths carefully. |
| Startup and cold launch | Measure launch time before and after enabling the control. |
| Crash reporting | Confirm stack traces and crash grouping are still operational enough for release support. |
| Release size | Confirm APK/AAB growth fits your distribution requirements. |
Rollout Guidance
| Stage | Recommendation |
|---|---|
| Development | Enable lighter obfuscation first, then add Encrypt All Code once core flows are stable. |
| Staging | Test a production-like protected build on physical devices, real accounts, and representative network conditions. |
| Production | Release only after startup, crash, performance, and support workflows are validated. |
| Incident response | Keep a known-good protected build profile available so you can quickly rebuild if an incompatibility is found. |
User And App Impact
Users should not see a different app flow when the control is compatible with the app. Teams may observe larger build artifacts, longer protected build times, and small runtime overhead depending on app size and framework usage.
Because this is an advanced hardening control, introduce it deliberately and validate the full release path before enabling it for all production users.
