<h1>Certificate Check Can End With Locally Saved Certificate</h1>\n
If this option is checked, the check of the certificate chain can end with a 
locally saved certificate.\n

Locally saved certificates are your own certificates as well as the 
certificates of communication partners and certification authorities (CAs).\n
