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.

🎑Student project - steganography in *.bmp images 🏢

🖼️ Embed and compress data securely in color images using Huffman coding and histogram shifting for efficient, invisible steganography.

Gradus is a Python steganography tool that uses histogram shifting techniques to hide AES-encrypted text messages within PNG images. It combines cryptographic security with advanced peak-detection algorithms to embed data invisibly while maintaining image quality.
