Test Data: Visual Fingerprints

[tomrittervg]

We should extract and adapt the OpenSSH Visual Host Keys code to generate fingerprints. It should also generate two fingerprints that are matches to 2^80 complexity.

• One 'match' should have the difference completely at random
• One 'match' should have the location of the characters as close as possible, but the less 'computation' expended on the type of character

In addition to OpenSSH fingerprints we should consider "vash" and "Hash Visualization":

Hash Visualization:

The OpenSSH algorithm is described here:

Figuring out which is best, and then how to simulate a 2^80 attack seems like a ton of work, probably a study / research project in itself. Dunno if we have the resources for this, or maybe we should scale back and just focus on the text formats?
