This read-only DisplayString (0-255 chars) identifies the SSL certificate used for the NetScreen device's HTTPS web management interface for a given virtual system. An admin checks this value to confirm which certificate is currently bound to the WebUI's SSL service, which matters for verifying that management sessions are protected by the expected certificate rather than a stale or self-signed one. For example, the value might read something like 'self-cert' or a certificate name/label configured on the device. It is read alongside nsSetWebSSLCipher, which reports the cipher algorithm used alongside that certificate.
