All Implemented Interfaces:

JWSModule

public class SoftwareFakeJWSModule
extends AbstractJWSModule

SIMPLE and NOT REUSABLE demo for a trivial signature module In a real cash box this would be represented by an HSM, a smart card or e.g. a cloud service capable of creating SHA256withECDSA signatures (according to Detailspezifikation ABS 2)

                             String keyIdForClosedSystem)
                      throws GeneralSecurityException

this signature device is based on certificates and could therfore be used by open and closed systems for open systems the parameter keyIdForClosedSystem needs to be supplied. open systems do not require this parameter, since the serial number of the certificate is used as identifier

Parameters:

rkSuite - suite for this signature device

keyIdForClosedSystem - key-id, needs to be supplied if the signature device is used for a closed system

Throws:

GeneralSecurityException
