Configuring the Expiration Check Method for Received Certificates

You can verify whether the certificate received from the other party during communication is valid by sending a query to the OCSP (online certificate status protocol) responder (a server that supports OCSP). Configure the certificate verification level and the OCSP responder to connect to. These should be registered by the administrator.
