byron 0.8a1.dev47

Multi-purpose extensible self-adaptive optimizer and fuzzer

Byron is a generic optimizer designed to support source code fuzzing, either in assembly or in higher-level languages. It begins by generating a set of random programs, which are then iteratively improved by an evolutionary algorithm. It can handle complex, realistic structures containing local and global variables, conditional and looping statements, and subroutines.

Candidate solutions do not need to be designed, but merely evaluated using an external tool, such as an interpreter or a simulator. Different types of parallelization are supported out of the box, from simple multithreading to the creation of temporary directories where multiple subprocesses are concurrently spawned.

⚠️ Byron is currently in alpha and under active development

Installation

As simple as

pip install --upgrade byron

A few dependencies can enhance Byron functionalities, but are not strictly required. You can get them all with

pip install --upgrade "byron[full]"

Documentation

None yet, but some HOWTO's and examples are available in the development repo.
