Cybersecurity & Ethical HackingGoMIT

Abstract

Steganography is an open-source Cybersecurity & Ethical Hacking project. Pure Golang Library that allows LSB steganography on images using ZERO dependencies. Steganography is a library written in Pure go to allow simple LSB steganography on images. It is capable of both encoding and decoding images. It is built using Go. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.

1. Introduction

Steganography is a library written in Pure go to allow simple LSB steganography on images. It is capable of both encoding and decoding images. It can store files of any format. This library is inspired by Stego by EthanWelsh, a command line utility with the same purpose.

Write mode is used to take a message and embed it into an image file using LSB steganography in order to produce a secret image file that will contain your message.

Read mode is used to read an image that has been encoded using LSB steganography, and extract the hidden message from that image.

2. Objective

Pure Golang Library that allows LSB steganography on images using ZERO dependencies

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