public class ArchiveTimeStamp
extends org.bouncycastle.asn1.ASN1Object

Implementation of the Archive Timestamp type defined in RFC4998.

• RFC 4998

  ASN.1 Archive Timestamp

  ArchiveTimeStamp ::= SEQUENCE { digestAlgorithm [Ø] AlgorithmIdentifier OPTIONAL, attributes [1] Attributes OPTIONAL, reducedHashtree [2] SEQUENCE OF PartialHashtree OPTIONAL, timeStamp ContentInfo}

  PartialHashtree ::= SEQUENCE OF OCTET STRING

  Attributes ::= SET SIZE (1..MAX) OF Attribute

Method Details

getInstance

public static ArchiveTimeStamp getInstance(Object obj)

Return an ArchiveTimestamp from the given object.

Parameters:

obj - the object we want converted.

Returns:

an ArchiveTimestamp instance, or null.

Throws:

IllegalArgumentException - if the object cannot be converted.

getDigestAlgorithmIdentifier

public org.bouncycastle.asn1.x509.AlgorithmIdentifier getDigestAlgorithmIdentifier()

getTimeStampDigestValue

public byte[] getTimeStampDigestValue()

getDigestAlgorithm

public org.bouncycastle.asn1.x509.AlgorithmIdentifier getDigestAlgorithm()

Return the contents of the digestAlgorithm field - null if not set.

Returns:

the contents of the digestAlgorithm field, or null if not set.

getHashTreeLeaf

public PartialHashtree getHashTreeLeaf()

Return the first node in the reduced hash tree which contains the leaf node.

Returns:

the node containing the data hashes, null if no reduced hash tree is present.

getReducedHashTree

public PartialHashtree[] getReducedHashTree()

getTimeStamp

public ContentInfo getTimeStamp()
