NAME
       Net::DNS::RR::DS - DNS DS resource record


SYNOPSIS
       "use Net::DNS::RR;"


DESCRIPTION
       Class for Delegation signer (DS) resource records.


METHODS
       In addition to the regular methods

   create
       This constructor takes a key object as argument and will return a DS RR object.

       $dsrr=create Net::DNS::RR::DS($keyrr, (
                         digtype => "SHA256" ); $keyrr->print; $dsrr->print;

       The digest type defaults to SHA1.

   verify
       The verify method will return 1 if the hash over the key provided in the argument matches the data in the
       $dsrr itself i.e. if the DS pointing to the DNSKEY from the argument. It will return 0 otherwise.

       $dsrr->($keyrr);

   algorithm
           print "algoritm" = ", $rr->algorithm, "\n";

       Returns the RR's algorithm field in decimal representation

           1 = MD5 RSA
           2 = DH
           3 = DSA
           4 = Elliptic curve

   digest
           print "digest" = ", $dsrr->digest, "\n";

       Returns the SHA1 digest over the label and key in hexadecimal representation

   digestbin
           $digestbin =  $dsrr->digestbin;

       Returns the digest as  binary material

   keytag
           print "keytag" ." = ". $dsrr->keytag . "\n";

       Returns the key tag of the key. (RFC2535 4.1.6)

   digtype
          print "digest type" . " = " . $dsrr->digtype ."\n";

       Returns the digest type of the DS RR.

   babble
          print $dsrr->babble;

       Returns the 'BabbleBubble' representation of the digest. The 'BabbleBubble' string may be handy for
       telephone confirmation.

       The 'BabbleBubble' string returned as a comment behind the RDATA when the string method is called.
