perl-Digest-BubbleBabble -- Create bubble-babble fingerprints
http://search.cpan.org/dist/Digest-BubbleBabble/
Digest::BubbleBabble takes a message digest (generated by either of
the MD5 or SHA-1 message digest algorithms) and creates a fingerprint
of that digest in "bubble babble" format. Bubble babble is a method of
representing a message digest as a string of "real" words, to make the
fingerprint easier to remember. The "words" are not necessarily real
words, but they look more like words than a string of hex characters.
Bubble babble fingerprinting is used by the SSH2 suite (and,
consequently, by Net::SSH::Perl, the Perl SSH implementation) to
display easy-to-remember key fingerprints. The key (a DSA or RSA key)
is converted into a textual form, digested using Digest::SHA1, and run
through bubblebabble to create the key fingerprint.
