C Code Obfuscator & Deobfuscator ⚙️

The C Code Obfuscator and Deobfuscator is a Python-based tool designed to enhance the security and confidentiality of C source code. The obfuscator transforms the original code into a less readable and more complex version by renaming variables, functions, and other identifiers. The deobfuscator reverses this process, restoring the code to its original, readable state.

Features 🔍

• 🔒 Variable Renaming: Consistently renames all variables to obfuscated identifiers.
• 🎨 Function Renaming: (If implemented) Renames functions to obscure names.
• 🔄 Consistent Mapping: Ensures that all instances of a variable are renamed consistently.
• 🔬 Deobfuscation: Reverts obfuscated code back to its original form using the mapping table.
• ⚡ Error Handling: Robust parsing and error reporting for invalid or unexpected code constructs.
• 🔗 Web Interface: Upload and process files via an interactive web page.
• 🔧 Extensible Design: Easily extendable to support additional C language features.

1. Launch the Web Interface

cd webapp

Run the following command to start the app:

python app.py

2. Upload Your C Source File

Access the web page at http://127.0.0.1:5000 and upload your C source file for obfuscation.

3. Obfuscation & Deobfuscation

• Once uploaded, the tool will:
  • Generate an obfuscated version of your C code.
  • Provide a zipped file containing:
    • The deobfuscated code.
    • The mapper.json file for identifier mapping.
• To deobfuscate:
  • Upload the obfuscated .c file and the mapper.json file on the same page.

Interactive Web Features 🌟

• Sleek & Fun UI:
  • Buttons with animations
  • Real-time progress updates
• Friendly Notifications:
  • Success ✅ and error ❌ alerts.
• Download Links: Easily download your zipped files with a single click.

Example Workflow

1. Prepare Your C Source File (e.g., sample_code.c).
2. Run the app and upload your file.
3. Download the zipped results.
4. Use the mapper.json file to deobfuscate, if needed.
