public class ArchiveTimeStamp
extends ASN1Object

Implementation of the Archive Timestamp type defined in RFC4998.

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
