Advanced Python code protection beyond pyc files

Universal Python Code Obfuscator & VM Loader

This repo proposes using an obfuscation and encryption approach for Python code.

Understanding Python Bytecode Vulnerabilities

Structural Transparency

• Preservation of function signatures and class hierarchies
• Retention of original control flow patterns
• Maintained symbol references and name bindings

Decompilation Vulnerabilities

• Deterministic bytecode generation patterns
• Preserved type information and annotations
• Recoverable import hierarchies

Why PyE?

Standard Python bytecode (.pyc files) is easily decompilable due to several inherent limitations:

• Multi-layered protection strategy
• Advanced encryption techniques
• Custom execution environment

Inspiration

Common Vulnerabilities in Open Source AI packages:

• Easily bypassed safety checks
• Modifiable content filters
• Exposed prompt sanitization

Critical Protection Needs

• Model interaction guardrails
• Input/output filtering logic
• Usage tracking mechanisms
• Security parameter preservation

Installation & Usage

Installation

pip install pye-extension

Basic Usage

Compile your sensitive Python file:

pyehandler compile your_script.py

Limitations

• While significantly more secure than .pyc, no protection is unbreakable. DO NOTE THIS IS EXTREMELY IMPORTANT
• Performance may be slower
• Debug information is limited in protected modules
