Table 72 Trusted CA Details
LABEL DESCRIPTION
Name This field displays the identifying name of this certificate. If you want to change
the name, type up to 31 characters to identify this key certificate. You may use
any character (not including spaces).
Property
Default self-signed
certificate which
signs the imported
remote host
certificates.
Select this check box to have the ZyAIR use this certificate to sign the trusted
remote host certificates that you import to the ZyAIR. This check box is only
available with self-signed certificates.
If this check box is already selected, you cannot clear it in this screen, you must
select this check box in another self-signed certificate’s details screen. This
automatically clears the check box in the details screen of the certificate that was
previously set to sign the imported trusted remote host certificates.
Certificate Path Click the Refresh button to have this read-only text box display the end entity’s
certificate and a list of certification authority certificates that shows the hierarchy
of certification authorities that validate the end entity’s certificate. If the issuing
certification authority is one that you have imported as a trusted certification
authority, it may be the only certification authority in the list (along with the end
entity’s own certificate). The ZyAIR does not trust the end entity’s certificate and
displays “Not trusted” in this field if any certificate on the path has expired or
been revoked.
Refresh Click Refresh to display the certification path.
Certificate
Information
These read-only fields display detailed information about the certificate.
Type This field displays general information about the certificate. CA-signed means
that a Certification Authority signed the certificate. Self-signed means that the
certificate’s owner signed the certificate (not a certification authority). X.509
means that this certificate was created and signed according to the ITU-T X.509
recommendation that defines the formats for public-key certificates.
Version This field displays the X.509 version number.
Serial Number This field displays the certificate’s identification number given by the certification
authority.
Subject This field displays information that identifies the owner of the certificate, such as
Common Name (CN), Organizational Unit (OU), Organization (O) and Country
(C).
Issuer 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.
Signature Algorithm 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 ras-pkcs1-md5 (RSA public-private key encryption algorithm
and the MD5 hash algorithm).
Valid From 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.
Valid To 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.
