LSB Steganography Tool is a Python-based digital steganography tool that allows you to hide secret messages or files within ordinary images with minimal visible changes. It uses the Least Significant Bit (LSB) technique combined with a randomized bit embedding approach, making the embedded data harder to detect by unauthorized parties. To further ensure the security of the hidden content, the tool incorporates military-grade AES encryption. It supports various image formats—particularly PNG due to its lossless nature—and features a simple and intuitive Command Line Interface (CLI) for ease of use.

This project is developed using Python, leveraging NumPy for efficient image processing, Pillow (PIL) for image manipulation, and PyCryptodome for encryption and decryption purposes. By combining digital image processing, cryptography, and information security concepts, this tool offers a practical solution for secure and covert communication. It is well-suited for anyone concerned with digital privacy, cybersecurity enthusiasts, as well as students and researchers studying information hiding techniques.
