Class SIGRecord

java.lang.Object

org.xbill.DNS.Record

org.xbill.DNS.SIGRecord

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable

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

                 long 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

getTypeCovered

public int getTypeCovered()

Returns the RRset type covered by this signature

getRRsetType

public int getRRsetType()

Returns the type of RRset that this record would belong to. For all types except SIG/RRSIG, this is equivalent to getType().

Overrides:

getRRsetType in class Record

Returns:

The type of record

See Also:

Type, RRset, Record.getRRsetType()

getAlgorithm

public int getAlgorithm()

Returns the cryptographic algorithm of the key that generated the signature

getLabels

public int 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 long getOrigTTL()

Returns the original TTL of the RRset

getExpire

public java.util.Date getExpire()

Returns the time at which the signature expires

getTimeSigned

public java.util.Date getTimeSigned()

Returns the time at which this signature was generated

getFootprint

public int 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
