Tweetable Polyglot Png

Abstract

1. Introduction

Pack up to 3MB of data into a tweetable PNG polyglot file.

Twitter strips unnecessary data from PNG uploads, however, they do not strip trailing data from the DEFLATE stream inside the IDAT chunk, provided that the overall image file meets the requirements to avoid being re-encoded.

2. Objective

Pack up to 3MB of data into a tweetable PNG polyglot file.

This project demonstrates how Python can be applied to a real-world Cybersecurity & Ethical Hacking problem.
