this is a test of encrypting an image using a floating point number, press space to scan in an image, then the "enc" block encrypts the image with the "KEY" variable, which can be any number, but needs to be low enough for scratch to handle. then the block "dec" decrypts the image data, and the image can be displayed with the "render" block the security isn't very good right now
thanks for @Blue_Random for image scanner and @Geotale for improving it
