So this is a tangent on a thought i had after reading the title, but it might be a cool idea that I'll not have the time to do anything with so feel free to use it:

Human checkable fingerprints for pubkeys/hashes dont really work. None of the schemes i've seen hold up under somebody willing to spend compute to get a near-enough collision to fool most people most of the time.

But we can take those random bits and transform them and feed them into a seeded image generation LLM, and then have a person remember/compare the deterministic output image.

You might even make the case its the perfect machine to create memorable-2-human image artifact from random data.
