.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Class for \s-1DNS\s0 Delegation Signer (\s-1DS\s0) resource record.
.SH "METHODS"
.IX Header "METHODS"
The available methods are those inherited from the base class augmented
by the type-specific methods defined in this package.
.PP
Use of undocumented package features or direct access to internal data
structures is discouraged and could result in program termination or
other unpredictable behaviour.
.SS "keytag"
.IX Subsection "keytag"
.Vb 2
\& $keytag = $rr\->keytag;
\& $rr\->keytag( $keytag );
.Ve
.PP
The 16\-bit numerical key tag of the key. (\s-1RFC2535\s0 4.1.6)
.SS "algorithm"
.IX Subsection "algorithm"
.Vb 2
\& $algorithm = $rr\->algorithm;
\& $rr\->algorithm( $algorithm );
.Ve
.PP
Decimal representation of the 8\-bit algorithm field.
.PP
\&\fIalgorithm()\fR may also be invoked as a class method or simple function
to perform mnemonic and numeric code translation.
.SS "digtype"
.IX Subsection "digtype"
.Vb 2
\& $digtype = $rr\->digtype;
\& $rr\->digtype( $digtype );
.Ve
.PP
Decimal representation of the 8\-bit digest type field.
.PP
\&\fIdigtype()\fR may also be invoked as a class method or simple function
to perform mnemonic and numeric code translation.
.SS "digest"
.IX Subsection "digest"
.Vb 2
\& $digest = $rr\->digest;
\& $rr\->digest( $digest );
.Ve
.PP
Hexadecimal representation of the digest over the label and key.
.SS "digestbin"
.IX Subsection "digestbin"
.Vb 2
\& $digestbin = $rr\->digestbin;
\& $rr\->digestbin( $digestbin );
.Ve
.PP
Binary representation of the digest over the label and key.
.SS "babble"
.IX Subsection "babble"
.Vb 1
\& print $rr\->babble;
.Ve
.PP
The \fIbabble()\fR method returns the 'BubbleBabble' representation of the
digest if the Digest::BubbleBabble package is available, otherwise
an empty string is returned.
.PP
BubbleBabble represents a message digest as a string of plausible
words, to make the digest easier to verify. The \*(L"words\*(R" are not
necessarily real words, but they look more like words than a string
of hex characters.
.PP
The 'BubbleBabble' string is appended as a comment when the string
method is called.
.SS "create"
.IX Subsection "create"
.Vb 1
\& use Net::DNS::SEC;
\&
\& $dsrr = create Net::DNS::RR::DS($keyrr, digtype => \*(AqSHA\-256\*(Aq );
\& $keyrr\->print;
\& $dsrr\->print;
.Ve
.PP
This constructor takes a key object as argument and will return the
corresponding \s-1DS\s0 \s-1RR\s0 object.
.PP
The digest type defaults to \s-1SHA\-1\s0.
.SS "verify"
.IX Subsection "verify"
.Vb 1
\& $verify = $dsrr\->verify($keyrr);
.Ve
.PP
The boolean verify method will return true if the hash over the key
\&\s-1RR\s0 provided as the argument conforms to the data in the \s-1DS\s0 itself
i.e. the \s-1DS\s0 points to the \s-1DNSKEY\s0 from the argument.
