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.
