Viewing certificates This section describes how to view certificates in the Certificate Manager. To view certificates: 1. In the HP ThinPro Control Panel, double-click Certificates. 2. In the Certificate Manager, select an option indicating the type of certificate to view, as follows: ● Local Root Certificate Authorities ● Root Certification Authorities ● Personnel Certificates NOTE: There are two types of certificate authorities (CAs): root CAs and intermediate CAs. For a certificate to be trusted, and often for a secure connection to be established, that certificate must have been issued by a CA that is included in the trusted store of the device that is connecting. The name of the site is specified within the certificate. If the certificate was not issued by a trusted CA, the connecting device (e.g., a web browser) will then check to see if the certificate of the issuing CA was issued by a trusted CA, and so on until either a trusted CA is found (at which point a trusted, secure connection will be established) or no trusted CA can be found (at which point the device will usually display an error). To facilitate the process of verifying a "chain" of trust, every certificate includes the fields "Issued To" and "Issued By". An intermediate CA will show different information in these two fields, showing a connecting device where to continue checking, if necessary, in order to establish trust. 3.
