NAME

       Net::DNS::RR::SSHFP - DNS SSHFP resource record

SYNOPSIS

	   use Net::DNS;
	   $rr = new Net::DNS::RR('name SSHFP algorithm fptype fp');

DESCRIPTION

       DNS SSH Fingerprint (SSHFP) resource records.

METHODS

       The available methods are those inherited from the base class augmented by the type-specific methods defined in this package.

       Use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or
       other unpredictable behaviour.

   algorithm
	   $algorithm = $rr->algorithm;

       The 8-bit algorithm number describes the algorithm used to construct the public key.

   fptype
	   $fptype = $rr->fptype;

       The 8-bit fingerprint type number describes the message-digest algorithm used to calculate the fingerprint of the public key.

   fp
	   $fp = $rr->fp;

       Hexadecimal representation of the fingerprint digest.

   fpbin
	   $fpbin = $rr->fpbin;

       Returns opaque octet string representing the fingerprint digest.

   babble
	   print $rr->babble;

       The babble() method returns the 'BabbleBubble' representation of the fingerprint if the Digest::BubbleBabble package is available,
       otherwise an empty string is returned.

       Bubble babble represents 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 'BubbleBabble' string is appended as a comment to the RDATA when the string method is called.

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.
