It's convenient to show unique (generated) graphic icon for fingerprint for user.

Jazzicon is useful tool for generating cute and sophisticated icon for arbitrary data. It will work for PGP fingerprint.

How's your opinion for generated icons?

I like the idea of using some identicon next to keys. The downside of jazzicons is that there isn't a rust library yet but that may be a problem for another day. There is a dart library so these could be added to our flutter app.
