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

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

 

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

This is the certificate’s message digest that the ZyWALL 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).

the name and/or set whether or not you want the ZyWALL to check the CRL that

 

the certification authority issues before trusting a certificate issued by the

 

certification authority.

20.11 Trusted Remote Hosts

Click SECURITY, CERTIFICATES, Trusted Remote Hosts to open the Trusted Remote Hosts screen. 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.

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