Net::DNS::RR::DS - DNS DS resource record
Class for Delegation signer (DS) resource records.
In addition to the regular methods
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.
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.
print "algoritm" = ", $rr->algorithm, "\n";
Returns the RR's algorithm field in decimal representation
1 = MD5 RSA 2 = DH 3 = DSA 4 = Elliptic curve
print "digest" = ", $dsrr->digest, "\n";
Returns the SHA1 digest over the label and key in hexadecimal representation
$digestbin = $dsrr->digestbin;
Returns the digest as binary material
print "keytag" ." = ". $dsrr->keytag . "\n";
Returns the key tag of the key. (RFC2535 4.1.6)
print "digest type" . " = " . $dsrr->digtype ."\n";
Returns the digest type of the DS RR.
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.
