public class SIGRecord

extends Record

Signature - A SIG provides the digital signature of an RRset, so that the data can be authenticated by a DNSSEC-capable resolver. The signature is usually generated by a key contained in a KEYRecord

See Also:

RRset, DNSSEC, KEYRecord

Fields inherited from class org.xbill.DNS.Record

dclass, name, ttl, type, wireLength

Constructor Summary

SIGRecord(Name _name, short _dclass, int _ttl, int _covered, int _alg, int _origttl, Date _expire, Date _timeSigned, int _footprint, Name _signer, byte[] _signature)
Creates an SIG Record from the given data

Method Summary

byte	getAlgorithm() Returns the cryptographic algorithm of the key that generated the signature
Date	getExpire() Returns the time at which the signature expires
short	getFootprint() Returns The footprint/key id of the signing key.
byte	getLabels() Returns the number of labels in the signed domain name.
int	getOrigTTL() Returns the original TTL of the RRset
byte[]	getSignature() Returns the binary data representing the signature
Name	getSigner() Returns the owner of the signing key
Date	getTimeSigned() Returns the time at which this signature was generated
short	getTypeCovered() Returns the RRset type covered by this signature
String	toString() Converts to a String

SIGRecord

public SIGRecord(Name _name,
                 short _dclass,
                 int _ttl,
                 int _covered,

                 Name _signer,
                 byte[] _signature)

Creates an SIG Record from the given data

Parameters:

covered - The RRset type covered by this signature

alg - The cryptographic algorithm of the key that generated the signature

origttl - The original TTL of the RRset

expire - The time at which the signature expires

timeSigned - The time at which this signature was generated

footprint - The footprint/key id of the signing key.

signer - The owner of the signing key

signature - Binary data representing the signature

Method Detail

toString

public String toString()

Converts to a String

Overrides:

toString in class Record

getTypeCovered

public short getTypeCovered()

Returns the RRset type covered by this signature

getAlgorithm

public byte getAlgorithm()

Returns the cryptographic algorithm of the key that generated the signature

getLabels

public byte getLabels()

Returns the number of labels in the signed domain name. This may be different than the record's domain name if the record is a wildcard record.

getOrigTTL

public int getOrigTTL()

Returns the original TTL of the RRset

getExpire

public Date getExpire()

Returns the time at which the signature expires

getTimeSigned

public Date getTimeSigned()

Returns the time at which this signature was generated

getFootprint

public short getFootprint()

Returns The footprint/key id of the signing key.

getSigner

public Name getSigner()

Returns the owner of the signing key

getSignature

public byte[] getSignature()

Returns the binary data representing the signature
