DESCRIPTION
This field displays identifying information about the certificate's issuing certification
authority, such as Common Name, Organizational Unit, Organization and Country.
With self-signed certificates, this is the same information as in the Subject Name
field.
This field displays the type of algorithm that was used to sign the certificate. Some
certification authorities use rsa-pkcs1-sha1 (RSA public-private key encryption
algorithm and the SHA1 hash algorithm). Other certification authorities may use rsa-
pkcs1-md5 (RSA public-private key encryption algorithm and the MD5 hash algorithm).
This field displays the date that the certificate becomes applicable. The text displays in
red and includes a Not Yet Valid! message if the certificate has not yet become
applicable.
This field displays the date that the certificate expires. The text displays in red and
includes an Expiring! or Expired! message if the certificate is about to expire or has
already expired.
This field displays the type of algorithm that was used to generate the certificate's key
pair (the ZyWALL/USG uses RSA encryption) and the length of the key set in bits (1024
bits for example).
This field displays the certificate's owner's IP address (IP), domain name (DNS) or e-
mail address (EMAIL).
This field displays for what functions the certificate's key can be used. For example,
"DigitalSignature" means that the key can be used to sign certificates and
"KeyEncipherment" means that the key can be used to encrypt text.
This field displays general information about the certificate. For example, Subject
Type=CA means that this is a certification authority's certificate and
Constraint=1" means that there can only be one certification authority in the
certificate's path.
This is the certificate's message digest that the ZyWALL/USG 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.
This is the certificate's message digest that the ZyWALL/USG 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.
This read-only text box displays the certificate or certification request in Privacy
Enhanced Mail (PEM) format. PEM uses lowercase letters, uppercase letters and
numerals to convert a 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).
Click this button and then Save in the File Download screen. The Save As screen
opens, browse to the location that you want to use and click Save.
Click OK to save your changes back to the ZyWALL/USG. You can only change the
name.
Click Cancel to quit and return to the Trusted Certificates screen.
