🔒 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.

SteganoCrypt uses LSB (Least Significant Bit) technique to embed data into the pixel values of images, making changes imperceptible to the human eye.

💡 Best Practices

  • ✅ Use PNG format for best results (lossless compression)
  • ✅ Choose larger images for hiding bigger files
  • ✅ Use strong passwords for sensitive data
  • ✅ Test extraction before sharing the image
  • ✅ Keep the original image safe as backup
  • âš ī¸ Avoid JPEG for critical data (lossy compression)
  • âš ī¸ Don't re-compress or edit the encoded image
