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
19       This constructor takes a key object as argument and will return a DS RR
20       object.
21
22       $dsrr=create Net::DNS::RR::DS($keyrr, (
23                         digtype => "SHA256" ); $keyrr->print; $dsrr->print;
24
25       The digest type defaults to SHA1.
26
27       verify
28
29       The verify method will return 1 if the hash over the key provided in
30       the argument matches the data in the $dsrr itself i.e. if the DS point‐
31       ing to the DNSKEY from the argument. It will return 0 otherwise.
32
33       $dsrr->($keyrr);
34
35       algorithm
36
37           print "algoritm" = ", $rr->algorithm, "\n";
38
39       Returns the RR's algorithm field in decimal representation
40
41           1 = MD5 RSA
42           2 = DH
43           3 = DSA
44           4 = Elliptic curve
45
46       digest
47
48           print "digest" = ", $dsrr->digest, "\n";
49
50       Returns the SHA1 digest over the label and key in hexadecimal represen‐
51       tation
52
53       digestbin
54
55           $digestbin =  $dsrr->digestbin;
56
57       Returns the digest as  binary material
58
59       keytag
60
61           print "keytag" ." = ". $dsrr->keytag . "\n";
62
63       Returns the key tag of the key. (RFC2535 4.1.6)
64
65       digtype
66
67          print "digest type" . " = " . $dsrr->digtype ."\n";
68
69       Returns the digest type of the DS RR.
70
71       babble
72
73          print $dsrr->babble;
74
75       Returns the 'BabbleBubble' representation of the digest. The 'Babble‐
76       Bubble' string may be handy for telephone confirmation.
77
78       The 'BabbleBubble' string returned as a comment behind the RDATA when
79       the string method is called.
