Points

the issuing certification authority of this certificate makes available. This field

 

 

also displays the domain names or IP addresses of the servers.

 

 

 

 

MD5 Fingerprint

This is the certificate’s message digest that the ZyXEL Device calculated using

 

 

the MD5 algorithm. You can use this value to verify with the certification

 

 

authority (over the phone for example) that this is actually their certificate.

 

 

 

 

SHA1 Fingerprint

This is the certificate’s message digest that the ZyXEL Device calculated using

 

 

the SHA1 algorithm. You can use this value to verify with the certification

 

 

authority (over the phone for example) that this is actually their certificate.

 

 

 

 

Certificate in PEM

This read-only text box displays the certificate or certification request in Privacy

 

(Base-64) Encoded

Enhanced Mail (PEM) format. PEM uses 64 ASCII characters to convert the

 

Format

binary certificate into a printable form.

 

 

You can copy and paste the certificate into an e-mail to send to friends or

 

 

colleagues or you can copy and paste the certificate into a text editor and save

 

 

the file on a management computer for later distribution (via floppy disk for

 

 

example).

12.4 The Trusted Remote Hosts Screens

This screen displays a list of the certificates of peers that you trust but which are not signed by one of the certification authorities on the Trusted CAs screen. Click Security > Certificates > Trusted Remote Hosts to open the Trusted Remote Hosts screen.

You do not need to add any certificate that is signed by one of the certification authorities on the Trusted CAs screen since the ZyXEL Device automatically accepts any valid certificate signed by a trusted certification authority as being trustworthy.
