Hi Stanislas thanks for your update. sorry i dont really understand if using trusted cert, because normally, i am using self sign. if im using self sign, i just generate CSR from IC box and then use OpenSSL to sign my cert and the after that i import the sign cert to IC. for IE and IC connection also need certificate, and i must import .pem cert into IE. but this way user will got warning message since the cert only self sign. so let say i want to avoid warning message what i must do? 1. Create CSR from IC 2. send CSR to CA 3. Import cert from CA Do CA will give .pem cert also for IE? Thanks Ucup
