With the trial course of ‘Image-to-Code Conversion by Expanded Password System’ provided at our new website https://www.mnemonicidentitysolutions.com/, you can try a simulation of having cryptographic keys re-generated on the fly from your image memory.

Select the same images again and notice the same code is generated, even when the images are shuffled, the same code is generated for the same set of images. This high-entropy code could be used as a mighty seed of cryptographic key. Imagine that a key opens a digital lock, the key is never stored *anywhere*, it is generated on each invocation.
