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.
