PyObfuscator

PyObfuscator is a Python tool for obfuscating Python code. It renames functions and variables with unique identifiers and encodes string literals using Base64 to enhance code security and make reverse-engineering more challenging.

Features

• Identifier Obfuscation: Replaces function and variable names with unique, non-descriptive names.
• String Encoding: Encodes string literals using Base64 to obscure their content.
• Command-Line Interface: Provides a simple way to specify input and output files via command-line arguments.

Installation

Ensure you have Python 3.x installed. There are no additional dependencies required.

Example

x = input("First number: ")
y = input("Second number: ")

if x > y :
  print("true")
else:
   print("false")

x = input(__builtins__.__import__("base64").b64decode(b"Rmlyc3QgbnVtYmVyOiA=").decode())
y = input(__builtins__.__import__("base64").b64decode(b"U2Vjb25kIG51bWJlcjog").decode())
if x > y:
    print(__builtins__.__import__("base64").b64decode(b"dHJ1ZQ==").decode())
else:
    print(__builtins__.__import__("base64").b64decode(b"ZmFsc2U=").decode())

Recommended Python Versions

• Python 3.6 and newer: The script uses features like f-strings and the ast.unparse() method, which were introduced in Python 3.6 and Python 3.9 respectively. Python 3.6 and later versions will work, but for the best support and additional features, Python 3.9 or newer is recommended.

Python Version Compatibility

1. Python 3.6:

• Supports f-strings and basic ast module functionality.

2. Python 3.7

• Adds improvements to the ast module and other features.

3. Python 3.8

• Further improvements and optimizations in the ast module.

4. Python 3.9 and newer

• Introduces ast.unparse(), which is used in your script. Python 3.9 and newer will ensure full compatibility and access to the latest features and improvements.

Usage

1. Obfuscate Code:

   python main.py -i input_file.py -o output_file.py

• -i specifies the input file containing the code to obfuscate.
• -o specifies the output file for the obfuscated code. If not provided, the output file will default to <input_file>.obf.py.

2. Example:

   python main.py -i my_script.py -o my_script.obf.py

   This command will read my_script.py, obfuscate the code, and save the result to my_script.obf.py.

3. Command-Line Options:

• -i, --input: Path to the input Python file to obfuscate (required).
• -o, --output: Path to the output file for the obfuscated code (optional).

Summary

For the best compatibility and to leverage the latest features, it's recommended to run the script on Python 3.9 or later. Python 3.6 and Python 3.7 will work but may not support all the latest improvements. Ensure that you test your script with the desired Python version to verify compatibility.

Error Handling

• If the input file does not exist, an error message will be displayed.
• A custom error message will guide users on correct usage if invalid arguments are provided.
