NAME
       Net::DNS::RR::DS - DNS DS resource record
SYNOPSIS
           use Net::DNS;
           $rr = new Net::DNS::RR('name DS keytag algorithm digtype digest');
           use Net::DNS::SEC;
           $ds = create Net::DNS::RR::DS(
               $dnskeyrr,
               digtype => 'SHA256',
               ttl     => 3600
               );
DESCRIPTION
       Class for DNS Delegation Signer (DS) resource record.
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.
   keytag
           $keytag = $rr->keytag;
           $rr->keytag( $keytag );
       The 16-bit numerical key tag of the key. (RFC2535 4.1.6)
   algorithm
           $algorithm = $rr->algorithm;
           $rr->algorithm( $algorithm );
       Decimal representation of the 8-bit algorithm field.
       algorithm() may also be invoked as a class method or simple function to
       perform mnemonic and numeric code translation.
   digtype
           $digtype = $rr->digtype;
           $rr->digtype( $digtype );
       Decimal representation of the 8-bit digest type field.
       digtype() may also be invoked as a class method or simple function to
       perform mnemonic and numeric code translation.
   digest
           $digest = $rr->digest;
           $rr->digest( $digest );
       Hexadecimal representation of the digest over the label and key.
   digestbin
           $digestbin = $rr->digestbin;
           $rr->digestbin( $digestbin );
       Binary representation of the digest over the label and key.
   babble
           print $rr->babble;
       The babble() method returns the 'BubbleBabble' representation of the
       digest if the Digest::BubbleBabble package is available, otherwise an
       empty string is returned.
       BubbleBabble represents a message digest as a string of plausible
       words, to make the digest easier to verify.  The "words" are not
       necessarily real words, but they look more like words than a string of
       hex characters.
       The 'BubbleBabble' string is appended as a comment when the string
       method is called.
   create
           use Net::DNS::SEC;
           $dsrr = create Net::DNS::RR::DS($keyrr, digtype => 'SHA-256' );
           $keyrr->print;
           $dsrr->print;
       This constructor takes a key object as argument and will return the
       corresponding DS RR object.
       The digest type defaults to SHA-1.
   verify
           $verify = $dsrr->verify($keyrr);
       The boolean verify method will return true if the hash over the key RR
       provided as the argument conforms to the data in the DS itself i.e. the
       DS points to the DNSKEY from the argument.
