Hiding Text in an Image Using Steganography

This project demonstrates how to hide and reveal secret text messages inside an image using Python and the Pillow library.

🔧 How It Works

• stegano_hide.py: Hides a text string inside an image by modifying the blue channel of each pixel.
• stegano_reveal.py: Reads the modified image and extracts the hidden message.

📁 Files Included

• input.png: Original image used for hiding the message.
• output.png: Image with hidden message embedded.
• stegano_hide.py: Script to embed text into the image.
• stegano_reveal.py: Script to extract hidden text.
• README.md: Project description.
