LABEL
DESCRIPTION
Name
This field displays the identifying name of this certificate. You can change the name. You
can use up to 31 alphanumeric and ;‘~!@#$%^&()_+[]{}’,.=-
characters.
Certification 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 certificate, it may be
the only certification authority in the list (along with the end entity’s own certificate).
The UAG 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field if any certificate on the path has expired or been revoked.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.
LDAP Server
Select this check box if the directory server uses LDAP (Lightweight Directory Access
Protocol). LDAP is a protocol over TCP that specifies how clients access directories of
certificates and lists of revoked certificates.
Address
Type the IP address (in dotted decimal notation) of the directory server.
Port
Use this field to specify the LDAP server port number. You must use the same server
port number that the directory server uses. 389 is the default server port number for
LDAP.
ID
The UAG may need to authenticate itself in order to assess the CRL directory server.
Type the login name (up to 31 ASCII characters) from the entity maintaining the server
(usually a certification authority).
Password
Type the password (up to 31 ASCII characters) from the entity maintaining the CRL
directory server (usually a certification authority).
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 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 UAG uses RSA encryption) and the length of the key set in bits (1024 bits for
example).
