Certification Path Click the Refresh button to have this read-only text box display the end entity’s
certificate and a list of certification authority certificates that shows the hierarchy of
certification authorities that validate the end entity’s certificate. If the issuing
certification authority is one that you have imported as a trusted certification
authority, it may be the only certification authority in the list (along with the end
entity’s own certificate). The ZyWALL does not trust the end entity’s certificate and
displays “Not trusted” in this field if any certificate on the path has expired or been
revoked.
Refresh Click Refresh to display the certification path.
