Class TimestampToken

sun.security.timestamp.TimestampToken

public class TimestampToken
extends java.lang.Object

This class provides the timestamp token info resulting from a successful timestamp request, as defined in RFC 3161. The timestampTokenInfo ASN.1 type has the following definition:

     TSTInfo ::= SEQUENCE {
         version                INTEGER  { v1(1) },
         policy                 TSAPolicyId,
         messageImprint         MessageImprint,
           -- MUST have the same value as the similar field in
           -- TimeStampReq
         serialNumber           INTEGER,
          -- Time-Stamping users MUST be ready to accommodate integers
          -- up to 160 bits.
         genTime                GeneralizedTime,
         accuracy               Accuracy                 OPTIONAL,
         ordering               BOOLEAN             DEFAULT FALSE,
         nonce                  INTEGER                  OPTIONAL,
           -- MUST be present if the similar field was present
           -- in TimeStampReq.  In that case it MUST have the same value.
         tsa                    [0] GeneralName          OPTIONAL,
         extensions             [1] IMPLICIT Extensions  OPTIONAL }

     Accuracy ::= SEQUENCE {

         millis     [0] INTEGER  (1..999) OPTIONAL,
