getTimestampFromDssService

public static java.lang.Object getTimestampFromDssService(byte[] dataToStamp,
                                                          java.lang.String applicationID,
                                                          java.lang.String signatureType)
                                                   throws SigningException

Method that obtains a timestamp from TS@.

Parameters:

dataToStamp - Parameter that represents the data to stamp.

applicationID - Parameter that represents the identifier of the client application.

signatureType - Parameter that represents the timestamp type to generate. The allowed values are:

• DSSConstants.TimestampForm.RFC_3161 for ASN.1 timestamp.
• DSSConstants.TimestampForm.XML for XML timestamp.

Returns:

an object that represents the timestamp. This object can be:

• An instance of TimeStampToken when the timestamp is ASN.1 type.
• An instance of Element when the timestamp is XML type.

Throws:

SigningException - If the method fails.

• DSSConstants.TimestampForm.RFC_3161 for ASN.1 timestamp.
• DSSConstants.TimestampForm.XML for XML timestamp.

idClient - Parameter that represents client id.

Returns:

an object that represents the timestamp. This object can be:

• An instance of TimeStampToken when the timestamp is ASN.1 type.
• An instance of Element when the timestamp is XML type.

Throws:

SigningException - If the method fails.
