How Can I Obfuscate Python Code to Protect Sensitive Information?

Obscuring Code in Python

Hiding source code in Python is crucial for safeguarding sensitive information or preventing unauthorized access. One approach is leveraging Python's built-in compiler to convert code into bytecode.

The command python -OO -m py_compile generates a .pyo file containing obfuscated bytecode, stripped of docstrings and comments. Renaming the .pyo file to .py allows for execution of the code without revealing its source.

Limitations:

This method provides limited obfuscation as the code can be decompiled (partially) using techniques mentioned in the first comment. Nonetheless, it may suffice in certain situations.

Additional Considerations:

• Imported modules should be obfuscated using the .pyc suffix.
• Python can be used with the -O flag to run obfuscated modules with the .pyo suffix.
