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.

8192 ximah-tuciz-barit-nukat-milyn-binoz-zymyl-rymyt-litos-tedeb-kaxex GlitchV2 (RSA)

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.

This looks like a Bubble Babble encoding of the SHA-1 digest of the public key blob.

You can use ssh-keygen -B to generate such a fingerprint for a given public key:

ssh-keygen -Bf /etc/ssh/ssh_host_rsa_key.pub
  • Fantastic, thank-you. Couldn't find this anywhere. For extra points, do you know of a way to get OpenSSH to print it in this format when VisualHostKey is set to yes? Mar 29, 2021 at 16:04

    Patch sshconnect.c replacing SSH_FP_RANDOMART with SSH_FP_BUBBLEBABBLE in all 3 locations. Otherwise it won't do that; this feature is exclusive to ssh-keygen. (It's likely there only for compatibility with other SSH clients.) Mar 29, 2021 at 16:08
