NAME

6       Net::DNS::RR::DS - DNS DS resource record
7

SYNOPSIS

9       "use Net::DNS::RR;"
10

DESCRIPTION

12       Class for Delegation signer (DS) resource records.
13

METHODS

15       In addition to the regular methods
16
17   create
18       This constructor takes a key object as argument and will return a DS RR
19       object.
20
21       $dsrr=create Net::DNS::RR::DS($keyrr, (
22                         digtype => "SHA256" ); $keyrr->print; $dsrr->print;
23
24       The digest type defaults to SHA1.
25
26   verify
27       The verify method will return 1 if the hash over the key provided in
28       the argument matches the data in the $dsrr itself i.e. if the DS
29       pointing to the DNSKEY from the argument. It will return 0 otherwise.
30
31       $dsrr->($keyrr);
32
33   algorithm
34           print "algoritm" = ", $rr->algorithm, "\n";
35
36       Returns the RR's algorithm field in decimal representation
37
38           1 = MD5 RSA
39           2 = DH
40           3 = DSA
41           4 = Elliptic curve
42
43   digest
44           print "digest" = ", $dsrr->digest, "\n";
45
46       Returns the SHA1 digest over the label and key in hexadecimal
47       representation
48
49   digestbin
50           $digestbin =  $dsrr->digestbin;
51
52       Returns the digest as  binary material
53
54   keytag
55           print "keytag" ." = ". $dsrr->keytag . "\n";
56
57       Returns the key tag of the key. (RFC2535 4.1.6)
58
59   digtype
60          print "digest type" . " = " . $dsrr->digtype ."\n";
61
62       Returns the digest type of the DS RR.
63
64   babble
65          print $dsrr->babble;
66
67       Returns the 'BabbleBubble' representation of the digest. The
68       'BabbleBubble' string may be handy for telephone confirmation.
69
70       The 'BabbleBubble' string returned as a comment behind the RDATA when
71       the string method is called.
