Encrypt Image

Upload a PNG image and enter a secret message to embed within it, along with an encryption key.

The application will:

1. Generate a secure Initialization Vector (IV)
2. Encrypt and embed the secret message into the image
3. Split the modified image into three separate fragments
4. Return the fragments as a downloadable ZIP file

Be sure to securely store your key as it is required to reconstruct the image and extract the hidden message.
