Project Overview

SteganoApp is a desktop application that implements steganography techniques to hide secret messages or images within carrier images. Using LSB (Least Significant Bit) manipulation, data can be concealed without visible changes to the image, perfect for secure communication.

Key Features

Hide text messages in images
Hide images within other images
Extract hidden text from encoded images
Extract hidden images from encoded files
User-friendly GUI interface
Support for various image formats

Technical Details

Language: JavaScript
Framework: Electron
Runtime: Node.js
Algorithm: LSB Steganography
Image Processing: Jimp / Sharp
Platform: Windows, macOS, Linux

Development Story

This project was born from my interest in cryptography and data security. I wanted to create a practical application that demonstrates how steganography works while providing a useful tool for secure communication through seemingly innocent images.
