Using this page, you can hide a secret, encrypted message inside an image that will be invisible to the naked eye and undetectable to everything but careful mathematical analysis. Even if detected, your message will be stored encrypted using a password of your choice, making your message all but impossible to read!
Hiding a message like this is known as steganography. It is part art form, part science and there are many different methods to do it. The Wikipedia article on steganography provides a good deal of information on the practice.
You can use either an image that you provide or a random tile from the mozaiq library. To use your own image, select 'browse' in the box at the top right. Leave this field blank to use a random mozaiq image.
Pass the message along to your fellow spies along with this website and they can recover you message on our decryption page.
