Chapter 16 Certificates

203

The certification authority certificate that you want to import has to be in one of these file 
formats:

• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 

certificates.

• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses 64 ASCII 

characters to convert a binary X.509 certificate into a printable form.

• Binary PKCS#7: This is a standard that defines the general syntax for data (including 

digital signatures) that may be encrypted. The ZyXEL device currently allows the 
importation of a PKS#7 file that contains a single certificate.

• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses 64 

ASCII characters to convert a binary PKCS#7 certificate into a printable form.

Click CERTIFICATES, My Certificates and then Import to open the My Certificate 
Import screen. Follow the instructions in this screen to save an existing certificate to the 
ZyXEL device, see the following figure.

request that was generated by the ZyXEL device.

Note: 2. The certificate you import replaces the corresponding request in the My 

Certificates screen.

Note: 3. You must remove any spaces from the certificate’s filename before you can 

import it.
