NAME

       Digest::BubbleBabble - Create bubble-babble fingerprints

SYNOPSIS

           # Create a fingerprint of a simple string.
           use Digest::BubbleBabble qw( bubblebabble );
           my $fingerprint = bubblebabble( Digest => "Pineapple" );

           # Create a fingerprint of a SHA-1 hash.
           use Digest::SHA qw( sha1 );
           $fingerprint = bubblebabble( Digest => sha1("hello") );

DESCRIPTION

       Digest::BubbleBabble takes a message digest (often 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::SHA,
       and run through bubblebabble to create the key fingerprint.

USAGE

       Digest::BubbleBabble conditionally exports one function called bubblebabble; 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::SHA.

       Returns the bubble babble form of the digest.
