sun.security.timestamp.TSRequest

public class TSRequest
extends java.lang.Object

This class provides a timestamp request, as defined in RFC 3161. The TimeStampReq ASN.1 type has the following definition:

     TimeStampReq ::= SEQUENCE {
         version           INTEGER { v1(1) },
         messageImprint    MessageImprint
           -- a hash algorithm OID and the hash value of the data to be
           -- time-stamped.
         reqPolicy         TSAPolicyId    OPTIONAL,
         nonce             INTEGER        OPTIONAL,
         certReq           BOOLEAN        DEFAULT FALSE,
         extensions        [0] IMPLICIT Extensions OPTIONAL }

     MessageImprint ::= SEQUENCE {
         hashAlgorithm     AlgorithmIdentifier,
         hashedMessage     OCTET STRING }

     TSAPolicyId ::= OBJECT IDENTIFIER

Constructor Detail

TSRequest

public TSRequest(byte[] hashValue,
         java.lang.String hashAlgorithm)

Constructs a timestamp request for the supplied hash value..

Parameters:

hashValue - The hash value. This is the data to be timestamped.

hashAlgorithm - The name of the hash algorithm.

Method Detail

setVersion

public void setVersion(int version)

Sets the Time-Stamp Protocol version.

Parameters:

version - The TSP version.

setPolicyId

public void setPolicyId(java.lang.String policyId)

Sets an object identifier for the Time-Stamp Protocol policy.

Parameters:

version - The policy object identifier.

setNonce

public void setNonce(java.math.BigInteger nonce)

Sets a nonce. A nonce is a single-use random number.

Parameters:

nonce - The nonce value.

requestCertificate

public void requestCertificate(boolean returnCertificate)

Request that the TSA include its signing certificate in the response.

Parameters:

returnCertificate - True if the TSA should return its signing certificate. By default it is not returned.

setExtensions

public void setExtensions(java.security.cert.X509Extension[] extensions)

Sets the Time-Stamp Protocol extensions.

Parameters:

extensions - The protocol extensions.

encode

public byte[] encode()
              throws java.io.IOException

Throws:

java.io.IOException
