Secret Message 🤫

🔍 What is Steganography?

Steganography is the practice of concealing messages or information within other non-secret data. Unlike encryption, which makes data unreadable, steganography hides the very existence of the message.

🎯 How It Works

This tool uses LSB (Least Significant Bit) steganography, modifying the least significant bits of image pixels to store your message. These changes are imperceptible to the human eye.

💡 Best Practices

Use PNG images for best results
Larger images can store more text
Avoid re-saving encoded images as JPG
Keep messages concise for better hiding

Note: While steganography can hide messages, it's not a replacement for proper encryption. For sensitive data, consider using additional encryption methods.
