Pypperoni Python Compiler Source Code

Python 3.9 obfuscator built on LibCST with a library of fun obfuscation techniques, including polynomial MBAs, runtime bytecode patching, etc.

An IR for Python VM, provided with indirect jump instructions.

haskell-like compiled language based on Python VM

A dialect of Lisp compiling to Python bytecode

GTK graphical user interface for Python bytecode disassembly, reverse engineering, and malware analysis using the xdis disassembler library.

Bytecode patching for the Python 3.6 zipfile module to permit null bytes in paths

Assembler for CPython bytecode in dis-like format with macros

A pure-Rust reverse-engineering IDE for CTF and malware analysis — disassembler, Rust-speaking decompiler, debugger, emulator, symbolic solver, malware triage, managed-format tooling (WASM/.NET/Java/DEX/pyc/JS), a CyberChef-style workbench, a built-in Academy, and an AI assistant on your own model (Claude plan/API, OpenAI or local).

pycociC is a high-performance Python utility and CLI tool for safely removing compiled Python bytecode (.pyc, .pyo) and Numba JIT caches (.nbc, .nbi). It recursively scans directories or entire disks, prunes empty pycache folders, and reports freed space. Perfect for CI/CD pipelines and maintaining clean project environments.

Python script that lets you generate HTML report of code object disassembly.

Django-compatible template library that compiles to a raw Python bytecode

cli to batch decompile .pyc files

Custom Python bytecode emulation.

CTF's Writeups

A modified CPython runtime that enables encrypted Python bytecode execution to protect source code and sensitive logic.

A small python bytecode obfuscator

A simple steganalysis tool for Stegosaurus steganography

Defensive Python program analysis framework with AST control flow graph recovery and constant propagation sandbox.

A hands-on guide to Advanced Python Engineering covering CPython internals, memory management, data structures, algorithms, namespaces, OOP, concurrency, optimization, and security. Features practical experiments, benchmarks, engineering notes, and production-grade capstone projects for building scalable, high-performance applications.
