Encrypt Image

Upload a PNG image and enter a secret message to embed within it, along with a 16-digit encryption key and Initialization Vector (IV).

The application will:
1. Encrypt and embed the secret message into the image
2. Split the modified image into three separate fragments
3. Return the fragments as a downloadable ZIP file

Be sure to securely store your key and IV as they are required to reconstruct the image and extract the hidden message.
