Syntax

public class RRSIGRecord : ResourceRecord, IWireSerialiser, ICloneable, IPresentationSerialiser

Remarks

Defined in RFC 4034 section 3.

Constructors

RRSIGRecord()

Creates a new instance of the RRSIGRecord class.

Declaration

public RRSIGRecord()

Properties

Algorithm

Identifies the cryptographic algorithm to create the Signature.

Declaration

public SecurityAlgorithm Algorithm { get; set; }

Property Value

Type	Description
SecurityAlgorithm	Identifies the type of key (RSA, ECDSA, ...) and the hashing algorithm.

KeyTag

The key tag of the DNSKEYRecord that validates the Signature.

Declaration

public ushort KeyTag { get; set; }

Property Value

Type	Description
UInt16	The KeyTag() method produces this value.

Labels

The number of labels in the original RRSIG RR owner name.

Declaration

public byte Labels { get; set; }

Property Value

Type	Description
Byte

Remarks

The significance of this field is that a validator uses it to determine whether the answer was synthesized from a wildcard.

OriginalTTL

The TTL of the covered RRset as it appears in the authoritative zone.

Declaration

public TimeSpan OriginalTTL { get; set; }

Property Value

Type	Description
TimeSpan	The resolution is 1 second.

Signature

The cryptographic signature.

Declaration

public byte[] Signature { get; set; }

Property Value

Type	Description
Byte[]	The format depends upon the Algorithm.

SignatureExpiration

The end date for the Signature.

Declaration

public DateTime SignatureExpiration { get; set; }

Property Value

Type	Description
DateTime	The resolution is 1 second.

SignatureInception

The start date for the Signature.

Declaration

public DateTime SignatureInception { get; set; }

Property Value

Type	Description
DateTime	The resolution is 1 second.

SignerName

The owner name of the DNSKEYRecord that validates the Signature.

Declaration

public DomainName SignerName { get; set; }

Property Value

Type	Description
DomainName

TypeCovered

The type of the RRset that is covered by this signature.

Declaration

public DnsType TypeCovered { get; set; }

Property Value

Type	Description
DnsType	One of the DnsType values.

Methods

ReadData(PresentationReader)

Read the textual representation of the data that is specific to the resource record Type.

Declaration

public override void ReadData(PresentationReader reader)

Parameters

Type	Name	Description
PresentationReader	reader	The source of the resource record's data.

Overrides

ResourceRecord.ReadData(PresentationReader)

Remarks

Derived classes must implement this method.

ReadData(WireReader, Int32)

Read the data that is specific to the resource record Type.

Declaration

public override void ReadData(WireReader reader, int length)

Parameters

Type	Name	Description
WireReader	reader	The source of the resource record's data.
Int32	length	The length, in bytes, of the data.

Overrides

ResourceRecord.ReadData(WireReader, Int32)

Remarks

Derived classes must implement this method.

WriteData(PresentationWriter)

Write the textual representation of the data that is specific to the resource record.

Declaration

public override void WriteData(PresentationWriter writer)

Parameters

Type	Name	Description
PresentationWriter	writer	The destination for the resource record's data.

Overrides

ResourceRecord.WriteData(PresentationWriter)

Remarks

Derived classes should implement this method.

By default, this will write the hex encoding of the GetData() preceeded by "#" and the number integer bytes.

WriteData(WireWriter)

Write the data that is specific to the resource record Type.

Declaration

public override void WriteData(WireWriter writer)

Parameters

Type	Name	Description
WireWriter	writer	The destination for the DNS object's data.

Overrides

ResourceRecord.WriteData(WireWriter)

Remarks

Derived classes must implement this method.
