RR::DS(3p)

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.
