.SH "NAME"
Net::LDNS::RR::RRSIG \- Type RRSIG record
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A subclass of Net::LDNS::RR, so it has all the methods of that class available in addition to the ones documented here.
.SH "METHODS"
.IX Header "METHODS"
.IP "\fBtypecovered()\fR" 4
.IX Item "typecovered()"
Returns a string with the name of the \s-1RR\s0 type this signature covers.
.IP "\fBalgorithm()\fR" 4
.IX Item "algorithm()"
Returns the algorithm number.
.IP "\fBlabels()\fR" 4
.IX Item "labels()"
Returns the number of labels that was used to calculate the signature.
.IP "\fBorigttl()\fR" 4
.IX Item "origttl()"
Returns the original \s-1TTL\s0 value.
.IP "\fBexpiration()\fR" 4
.IX Item "expiration()"
Returns the expiration time, as a time_t.
.IP "\fBinception()\fR" 4
.IX Item "inception()"
Returns the inception time, as a time_t.
.IP "\fBkeytag()\fR" 4
.IX Item "keytag()"
Returns the keytag.
.IP "\fBsigner()\fR" 4
.IX Item "signer()"
Returns the signer name.
.IP "\fBsignature()\fR" 4
.IX Item "signature()"
Returns the cryptographic signture in binary form.
.ie n .IP "verify($rrset_ref, $key_ref)" 4
.el .IP "verify($rrset_ref, \f(CW$key_ref\fR)" 4
.IX Item "verify($rrset_ref, $key_ref)"
Cryptographically verifies that the signature in this object matches the given RRset and at least one of the given keys. \f(CW$rrset_ref\fR should be a
reference to an array of \s-1RR\s0 objects, and \f(CW$key_ref\fR a reference to an array of Net::LDNS::RR::DNSKEY objects. This method simply returns a true
or false value, depending on the result och the check.
.ie n .IP "verify_str($rrset_ref, $key_ref)" 4
.el .IP "verify_str($rrset_ref, \f(CW$key_ref\fR)" 4
.IX Item "verify_str($rrset_ref, $key_ref)"
Takes exactly the same arguments as \fBverify()\fR and performs the same action, but instead of true/false it returns a string describing the result.
In the case of a successful result the message will be \*(L"All \s-1OK\*(R".\s0 For negative results, the string will describe the reason the verification failed.
.ie n .IP "verify_time($rrset_ref, $key_ref, $time, $msg)" 4
.el .IP "verify_time($rrset_ref, \f(CW$key_ref\fR, \f(CW$time\fR, \f(CW$msg\fR)" 4
.IX Item "verify_time($rrset_ref, $key_ref, $time, $msg)"
This is the \s-1XS\s0 method doing the work for the previous two methods. \f(CW$rrset_ref\fR and \f(CW$key_ref\fR are the same as for the other methods. \f(CW$time\fR is
the \f(CW\*(C`time_t\*(C'\fR value for which the validation should be made (for the previous two methods it is set to the current computer time). \f(CW$msg\fR should be
a writable scalar, and the string message describing the result will be but in it. The return value from the method is true/false.
