SSH has gone through several fingerprint formats and visualization methods. There are MD5 and SHA256 for formats. Hex, Base64 and ramdomart are different visualizations. For a short time, however, there was another visualization format that appears to use random five-letter words.

It appears to generate the word in the format consonant-vowel-consonant-vowel-consonant, which seems actually to be a reasonable way to generate basically pronounceable but random words.
I have several lists of ssh fingerprints in this format, but cannot find a reference to what or how they were generated.
