pyinstxtractor is a PyInstaller executable unpacker and Python bytecode recovery tool. It functions as a helper for decompiling compiled Python binaries by extracting bundled binaries and bytecode from executables created with PyInstaller.
The project includes a bytecode decryptor to remove encryption from extracted files and a header repair tool that restores corrupted headers. These capabilities ensure that extracted compiled files are compatible with bytecode decompilation software.
The utility covers reverse engineering of Python applications, supporting malware analysis workflows through the recovery of original source components and bundled assets from distributed binaries.
