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 ZyAIR to 
accept as trusted. The ZyAIR 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. 

SHA1 Fingerprint

This is the certificate’s message digest that the ZyAIR calculated using the 

SHA1 algorithm. 

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).

certificates.
