(Note: Modern versions of PyInstaller Extractor usually automate this header restoration step entirely, saving you from manual hex editing.) Phase 3: Decompiling PYC to PY Source Code

Because decompilation is highly accessible, deploying raw Python executables poses a security risk if your code contains proprietary algorithms or sensitive API keys. To safeguard your software, implement these security measures: 1. Code Obfuscation

Now, you're ready to start your own project. Choose the right tool for the job and happy extracting!

To get from an EXE to a readable .py file, you must follow two distinct stages: convert exe to py

Run the command line tool, passing your bytecode file as the target and redirecting the output to a new Python file: pycdc main.pyc > restored_script.py Use code with caution. Option B: Using Uncompyle6

PyInstaller does not actually turn Python into C++ or machine code. Instead, it takes three things and bundles them together into a package: Your Python code (compiled into .pyc files). The Python interpreter (the engine that runs the code). Any extra files or libraries your code needs. Choose the right tool for the job and happy extracting

However, if you have a legitimate reason (e.g., recovering your own lost code or analyzing malware in a sandbox), there are tools and techniques that can recover significant portions of the original logic.

Are you running into any (e.g., magic number mismatches) when trying to de-compile? If you share with third parties, their policies apply

While you cannot perfectly revert a compiled binary like C++ into its original source code, Python executables are different. Tools like PyInstaller or py2exe do not actually compile Python into machine code. Instead, they bundle the Python interpreter, your scripts, and required dependencies into a single compressed package.

: If the developer used a tool like PyArmor to obfuscate the code, the decompiled output will likely be unreadable or may fail to decompile entirely.

A embedded copy of Python required to run the code.

So, you have a .exe file that you need to run, modify, or inspect, but you only have access to the compiled version. You need to convert the exe file back into a Python script ( .py ), but you quickly discover that it isn't as simple as changing a file extension.

: A powerful command-line library for decompiling Python bytecode. It can be installed via pip install uncompyle6 and run as: uncompyle6 -o . your_file.pyc
