EYECRYPT is a tool I've made that allows you to experiment with encryption on images!
Encrypting an image typically makes it no longer readable as an image file, but here I've additionally processed the encrypted image so that it is readable, so you can see how the encryption alters the image data.
Simply upload any image of your choice (and optionally, specify a key), press the button that says 'Process', and it'll do its magic! The resulting image will be the image you uploaded passed through an encryption method.
The effect is most prominent in images with large areas of uniform color.
A 'key' is something that is used to encrypt an image, and it is also what is used to decrypt an image. The same image with the same encryption method and the same key will always produce the same result.
Here, the key can be any text at all, from a number or a message like "good morning".
If you don't have 'Show advanced options' selected, the image will be processed with a key of a random number from 0-1000.
For the web version, currently only DES. There are more encryption methods available in the executable/cli tool, which you can find on itch.io or github.
For me, I am simply fulfilling a desire of mine for this to be a readily available process. And for you, that is up for you to decide!
You could use this to study patterns that occur in certain encryption methods, or you could simply have fun and watch how images warp and transform through this process. You could even use the resulting images for your own projects! I do not own the output of this program, so feel free to do as you wish with the output images. You don't need to ask or credit me.
As an important note, this is primarily meant as a visualization tool, and should not be used for actual encryption purposes. The interesting visual effects that result from these encryptions are a visual representation of security vulnerabilities that would occur when using these encryption methods on more sensitive data.
With all that aside; have fun!
