Developmental Challenges

Our team came across the following developmental challenges:

  • Implementing JavaScript code obfuscation.
  • Integrating gRPC (Google Remote Procedure Call).
  • Implementing the react native bridge for the Native code which is unavailable in the react native community.
  • Implementation of RASP(Runtime App Self-Protection).

How did we resolve these development challenges?

We resolved all challenges to develop the desired solution. For implementing JS code obfuscation, we developed custom obfuscation techniques that involved renaming variables and functions with non-descriptive names, breaking code into smaller functions, and applying various transformations to the code to make it less readable. For gRPC integration, we divided the integration process into smaller, manageable tasks- defining the communication protocols, implementing encryption and decryption methods, and integrating gRPC. We employed SSL/TLS to secure the gRPC communication in transit and secure key storage mechanisms. For the RN bridge, we built a custom native module by writing platform-specific native code (Java for Android and Swift/Objective-C for iOS) that interfaces with our React Native code. For RASP, we customized the RASP solution’s configuration to align with the specific security needs of this banking app and configured security policies and rules to define how the RASP solution should respond to different types of threats.
