O-MVLL is an LLVM-based code obfuscator for native code that integrates with Clang and the Swift compiler via the LLVM pass manager, with obfuscation rules driven by a Python API. It targets Android NDK and iOS toolchains on AArch64 and ARM architectures with passes like control-flow flattening, anti-hooking, and string encoding.

Use cases

• obfuscate native C/C++ code in an Android NDK app
• protect iOS Swift and Objective-C binaries from reverse engineering
• flatten control flow of sensitive functions like password checks
• hide or encode strings in compiled native binaries
• add anti-hooking protections to mobile app native libraries
• selectively obfuscate functions via a Python configuration

When to choose

• you build mobile apps with native code and need reverse-engineering protection
• you want LLVM-pass-based obfuscation configurable in Python
• you target AArch64 or ARM on Android or iOS

When to avoid

• you need obfuscation for desktop x86 binaries or non-LLVM toolchains
• you only need Java/Kotlin/Dart-level code protection
• you require a fully turnkey app-shielding solution without compiler integration
