Image Cryptographer

Using this scenario you can easily encrypt any text you want into an image and increase the security with a password.
The text will be encrypted using the password and will then again be encrypted into the image.
So if you use the right images (very colorful images are the best once) it's really hard to even see that there is an encrypted message in the image.

To use your own images and save the encrypted images you first need to download the scenario.
When you play online you can only encrypt your user image.

If you encrypt your text using this scenario I don't think that anyone who hasn't got this scenario and the right password will be able to crack the code (maybe except the NSA).

You can either encrypt your user image when you play online or you can use any image you want if you download it. Just choose the image you want in the dropdownlist, write the text you want to encrypt into the 'Encrypting Text' field, add a password in the 'Password' field and click on encrypt image.

Very nice textboxes, not as buggy as my one.
