KiwiVM is a virtualization encryption software for mobile applications.
It is based on the Clang compiler extension and virtualizes specified functions when the project is compiled. With the features of a custom CPU instruction, once the code is encrypted and never decrypted, the attacker cannot restore the code and analyze the core business logic. Helps companies customize encryption for communications, payment, algorithms, and core technologies to avoid financial loss due to security issues.
- Deep Encryption: Custom CPU instructions, encrypted code will not be decrypted.
- Function Virtualization: Virtualization protection of code functions for iOS projects
- Full Architectures: Support all cpu architectures such as armv7、armv7s、arm64 etc.
- compatibility: The implementation of IR code based on LLVM has no compatibility problem
You can find the KiwiVM documentation on the website.
After purchasing the KiwiVM virtual machine, use the machine code generation tool provided by Kiwisec to extract the Key of the computer to be bound. Kiwisec will generate a unique KiwiVM toolkit based on Key, authorization time and enterprise information.
After executing the xcode file, the tool will automatically replace the default compiler of xcode, launch the xcode development tool, and automatically restore the original compiler after exiting.
Copy the header file in the include directory into your iOS project and refer to it as needed.
For functions that require virtualization protection, add the KIWIVM tag to notify the compiler to virtualize compilation.
Execute the build in the xcode tool
After exiting the xcode tool, KiwiVM's startup script automatically restores the original compiler

Relying on the technical advantages of the team, KiwiSec focuses on next-generation technology and product development in mobile safety. After 8 years of accumulation in compiler security technology, and 3 years’ continuous research and development, the original KiwiVM virtual machine product has completely solved the problems of weak protection and poor compatibility inherent in traditional technologies such as hardening and obfuscation, providing a convenient and effective security solution.
