355 Chapter 20 Certificates
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.

the issuing certification authority of this certificate makes available. This field
also displays the domain names or IP addresses of the servers.

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 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
(Base-64) Encoded
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
