SYNOPSIS
use Digest::BubbleBabble qw( bubblebabble );
use Digest::SHA1 qw( sha1 );
my $fingerprint = bubblebabble( Digest => sha1($message) );
DESCRIPTIONDigest::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, conse-
quently, by Net::SSH::Perl, the Perl SSH implementation) to display
easy-to-remember key fingerprints. The key (a DSA or RSA key) is con-
verted into a textual form, digested using Digest::SHA1, and run
through bubblebabble to create the key fingerprint.
USAGEDigest::BubbleBabble conditionally exports one function called bubble-
babble; to import the function you must choose to import it, like this:
use Digest::BubbleBabble qw( bubblebabble );
bubblebabble( Digest => $digest )
Currently takes only one pair of arguments, the key of which must be
Digest, the value of which is the actual message digest $digest. You
should generate this message digest yourself using either Digest::MD5
of Digest::SHA1.
Returns the bubble babble form of the digest.
