Certificate in PEM 
(Base-64) Encoded 
Format 

This read-only text box displays the certificate or certification request in Privacy 
Enhanced Mail (PEM) format. PEM uses 64 ASCII characters to convert the binary 
certificate into a printable form.  

You can copy and paste a certification request into a certification authority’s web 
page, an e-mail that you send to the certification authority or a text editor and save 
the file on a management computer for later manual enrollment. 

You can copy and paste a certificate into an e-mail to send to friends or colleagues 
or you can copy and paste a certificate into a text editor and save the file on a 
management computer for later distribution (via floppy disk for example).

Apply 

Click Apply to save your changes back to the ZyWALL. You can only change the 
name, except in the case of a self-signed certificate, which you can also set to be

certificates. 

Cancel 

Click Cancel to quit and return to the My Certificates screen. 

Click CERTIFICATES, Trusted CAs to open the Trusted CAs screen. This screen displays a summary list 
of certificates of the certification authorities that you have set the ZyWALL to accept as trusted. The 
ZyWALL accepts any valid certificate signed by a certification authority on this list as being trustworthy; 
thus you do not need to import any certificate that is signed by one of these certification authorities. See the 
following figure.
