12.4 The Trusted Remote Hosts Screens
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. Click Security > Certificates >
Trusted Remote Hosts to open the Trusted Remote Hosts 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 ZyXEL Device automatically accepts any valid certificate
signed by a trusted certification authority as being trustworthy.
CRL Distribution
Points
This field displays how many directory servers with Lists of revoked certificates
the issuing certification authority of this certificate makes available. This field
also displays the domain names or IP addresses of the servers.
MD5 Fingerprint This is the certificate’s message digest that the ZyXEL Device calculated using
the 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 ZyXEL Device 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
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 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).

certification authority.
