Method Detail

createRequest

public static iaik.tsp.TimeStampReq createRequest(iaik.cms.SignerInfo signerInfo,
                                                  iaik.asn1.ObjectID reqPolicy)
                                           throws iaik.tsp.TspException

Creates a TimeStampRequest for the given SignerInfo.

Parameters:

signerInfo - the SignerInfo to be time stamped

reqPolicy - the policy of the TSA from which to get a response, maybe null if we accept any TSA

Returns:

the time stamp request just created

Throws:

iaik.tsp.TspException - if some error occurs during time stamp creation

sendRequest

public static iaik.tsp.TimeStampResp sendRequest(iaik.tsp.TimeStampReq request,
                                                 java.lang.String tsaUrl)
                                          throws iaik.tsp.TspException

Sends the given time stamp request to the given TSA.

Parameters:

request - the time stamp request to be sent to the TSA

tsaUrl - the URL of the time stamp authority from which to get the time stamp

Throws:

iaik.tsp.TspException - if an error occurs during sending the request to the TSA (e.g. connecting to the TSA fails, ...)

java.lang.NullPointerException - if request or tsaUrl are null

timeStamp

public static void timeStamp(iaik.tsp.TimeStampToken tspToken,
                             iaik.cms.SignerInfo signerInfo)
                      throws iaik.tsp.TspException

Adds a SignatureTimeStampToken attribute to the given SignerInfo.

Parameters:

tspToken - the time stamp token to be added as attribute

signerInfo - the SignerInfo to be time stamped

Throws:

iaik.tsp.TspException - if some error occurs when adding the attribute

validateResponse

public static void validateResponse(iaik.tsp.TimeStampResp response,
                                    iaik.tsp.TimeStampReq request)
                             throws iaik.tsp.TspException

Validates the response received from the TSA.

Parameters:

response - the time stamp response to be validated

request - the time stamp request that has been sent

Throws:

iaik.tsp.TspException - if the response is invalid (wrong MessageImprint, missing certificate,...)

validateSignatureTimeStampToken

public static void validateSignatureTimeStampToken(iaik.cms.SignerInfo signerInfo)
                                            throws iaik.tsp.TspException

Validates an unsigned SignatureTimeStampToken contained in the given SignerInfo.

Parameters:

signerInfo - the SignerInfo containing the SignatureTimeStampToken attribute

Throws:

iaik.tsp.TspException - if the time stamp token validation fails

java.lang.NullPointerException - if the SignerInfo does not contain a SignatureTimeStampToken as expected
