Please pay attention to the fact that all customers and partners which use still for ZertES (SigE) in Switzerland the CA2 root certificate and have not switched over to the new CA4 claimed ID will not be able to sign any more after end of this year. Thus we kindly request those partners and customers which have not already done the switch to CA4 should now start the switch over of their signing application. Our support sent detail informations how to proceed.
