Why Choose Obfuz?​

  • Powerful Features: Provides robust obfuscation and code protection capabilities comparable to commercial tools.
  • Deep Unity Integration: Optimized for Unity workflows, automatically handling all special cases except reflection (e.g., MonoBehaviour names cannot be obfuscated), working well with zero configuration.
  • Quick Integration: Simply configure which assemblies to obfuscate and integrate code obfuscation in just three minutes.
  • Stable and Reliable: Comprehensive automated test projects with over 3000 test cases covering almost all common code scenarios.
  • Hot Update Support: Supports popular code hot update solutions like HybridCLR and xLua.
  • Agile Development: Quick response to developer needs, rapid bug fixes, and timely follow-up on the latest changes in Unity and Unite Engine.

Features​

  • Polymorphic DLL Files: Custom structurally randomized DLL file format with different structures on each release, effectively resisting cracking and tampering.
  • Symbol Obfuscation: Supports rich configuration rules and incremental obfuscation for flexible and efficient code protection.
  • Constant Obfuscation: Obfuscates constants like int, long, float, double, string, and arrays to prevent reverse engineering.
  • Variable Memory Encryption: Encrypts variables in memory to enhance runtime security.
  • Evaluation Stack Obfuscation: Obfuscates variables in the execution stack to increase reverse engineering difficulty. (Disabled in v3.0.0)
  • Expression Obfuscation: Obfuscates most common operations like add and sub.
  • Call Obfuscation:打乱 function call structures to increase cracking difficulty.
  • Control Flow Obfuscation: Control flow flattening to disrupt code execution flow, significantly increasing reverse engineering difficulty.
  • Random Encryption Virtual Machine: Generates randomized virtual machines to effectively resist decompilation and cracking tools.
  • Static and Dynamic Decryption: Combines static and dynamic decryption to prevent offline static analysis.
  • Obfuscation Polymorphism: Generates different obfuscated code by configuring different generation keys and random seeds.
  • Garbage Code Generation: Supports multiple garbage code generation methods to improve App Store and Google Play review pass rates.
  • Code Watermarking: Embeds traceable watermarks.
  • Deep Unity Integration: Seamlessly integrates with Unity workflows, ready to use with simple configuration.
  • Hot Update Support: Fully compatible with hot update frameworks like HybridCLR and xLua, ensuring smooth dynamic code updates.
  • DOTS Compatibility: Compatible with all versions of DOTS without configuration.
