Open-source alternatives to Xortool

An MCP (Model Context Protocol) server that brings the capabilities of the enigmapython library to LLMs, allowing them to encrypt and decrypt messages using historically accurate Enigma machine emulators

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 throug

This project is a binary static analysis tool designed to recover hidden and non-standard encoded strings from compiled binaries. It functions as a malware analysis utility and string decryptor, extracting obfuscated text to reveal concealed program behavior without executing the code. The tool automates the recovery of embedded strings through a combination of emulated instruction execution and abstract syntax tree evaluation. It utilizes pattern-based heuristic detection to identify obfuscation routines and employs cross-platform binary parsing to process multiple executable formats. The s

RsaCtfTool is a specialized cryptography suite designed for solving capture-the-flag challenges. It serves as a cryptanalysis and key recovery tool used to derive private keys and decrypt data from weak RSA public key implementations. The tool functions as an integer factorization toolkit, employing a variety of mathematical attacks and algorithms to decompose large composite numbers into their prime factors. It integrates with external prime number databases to accelerate the factorization process and identifies specific mathematical vulnerabilities in key generation. Its capabilities cover

python-uncompyle6 is a Python bytecode decompiler and reverse engineering tool designed to convert compiled bytecode files back into human-readable source code. It functions as a source code recoverer and bytecode disassembler, allowing for the analysis of internal program logic and the reconstruction of original language constructs. The tool provides cross-version support, enabling the analysis and recovery of source code from bytecode created across multiple different versions of the Python interpreter. This allows it to operate as a cross-version bytecode analyzer that can interpret varied
