Table 113 My Certificate 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 certificate. You may use any
	character (not including spaces).
Property	Select this check box to have the ZyWALL use this certificate to sign the trusted
Default self-signed	remote host certificates that you import to the ZyWALL. This check box is only

	automatically clears the check box in the details screen of the certificate that was
	previously set to sign the imported trusted remote host certificates.
Certification Path	Click the Refresh button to have this read-only text box display the hierarchy of
	certification authorities that validate the certificate (and the certificate itself).
	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 certificate itself). If the certificate is a self-signed certificate, the
	certificate itself is the only one in the list. The ZyWALL does not trust the
	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	expired or been revoked.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	These read-only fields display detailed information about the certificate.
Information
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 or generated by the ZyWALL.
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 as the Subject Name field.
Signature Algorithm	This field displays the type of algorithm that was used to sign the certificate. The
	ZyWALL uses rsa-pkcs1-sha1 (RSA public-private key encryption algorithm and
	the SHA1 hash algorithm). Some certification authorities may use rsa-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.
Key Algorithm	This field displays the type of algorithm that was used to generate the
	certificate’s key pair (the ZyWALL uses RSA encryption) and the length of the
	key set in bits (1024 bits for example).
