Speaking of human-readable, I really like ssh's "randomart" visualizations of ssh fingerprints.[1][2][3]
They're much easier for humans to differentiate than the usual long string of hex characters (even 26 characters is too long to reliably compare when a single mismatched character might make all the difference).
Examples of randomart:
Generating public/private rsa key pair.
The key fingerprint is:
05:1e:1e:c1:ac:b9:d1:1c:6a:60:ce:0f:77:6c:78:47 you@i
The key's randomart image is:
+--[ RSA 2048]----+
| o=. |
| o o++E |
| + . Ooo. |
| + O B.. |
| = *S. |
| o |
| |
| |
| |
+-----------------+
Generating public/private dsa key pair.
The key fingerprint is:
b6:dd:b7:1f:bc:25:31:d3:12:f4:92:1c:0b:93:5f:4b you@i
The key's randomart image is:
+--[ DSA 1024]----+
| o.o |
| .= E.|
| .B.o|
| .= |
| S = .|
| . o . .= |
| . . . oo.|
| . o+|
| .o.|
