Tool for hiding and extracting data within PNG files

Steganography implemented in C using Least Significant Bit (LSB) technique to securely hide and retrieve secret data within image files.

A comprehensive steganography system that securely embeds compressed data within color images using Huffman coding and histogram shifting algorithms. Features multi-channel RGB encoding with 3x capacity increase, lossless data recovery, and comprehensive quality analysis tools.

This is notes, mainly for myself. I decided to make them public.

Course Work: Creating Mini Data Encryption Standard with CBC mode. It Encrypts input data of format: "10 Alphabets"+"."+"10 digit number"+" ". Example: "hellothere.1234567890 "

Comprehensive resource on OOP principles (Encapsulation, Inheritance, Polymorphism, Abstraction), advanced concepts (Interfaces, Abstract Classes, Nested Classes, Lambda Expressions, Generics), and design patterns (Singleton, Factory, Adapter, Strategy). Includes detailed docs, Java/C++ code examples, diagrams, and exercises. Contributions welcome!
