Chapter 35 Certificates Table 160 Configuration > Object > Certificate > My Certificates > Edit (continued) LABEL Certificate Information Type Version Serial Number Subject Issuer DESCRIPTION These read-only fields display detailed information about the certificate. 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. This field displays the X.509 version number. This field displays the certificate's identification number given by the certification authority or generated by the UAG. This field displays information that identifies the owner of the certificate, such as Common Name (CN), Organizational Unit (OU), Organization (O), State (ST), and Country (C). 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. "none" displays for a certification request. Signature Algorithm This field displays the type of algorithm that was used to sign the certificate. The UAG 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. "none" displays for a certification request. Valid To This field displays the date that the certificate expires. The text displays in red and includes an Expired! message if the certificate has expired. "none" displays for a certification request. 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). Subject Alternative This field displays the certificate owner's IP address (IP), domain name (DNS) or e-mail Name address (EMAIL). Key Usage 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. Basic Constraint This field displays general information about the certificate. For example, Subject Type=CA means that this is a certification authority's certificate and "Path Length Constraint=1" means that there can only be one certification authority in the certificate's path. This field does not display for a certification request. MD5 Fingerprint This is the certificate's message digest that the UAG calculated using the MD5 algorithm. SHA1 Fingerprint This is the certificate's message digest that the UAG calculated using the SHA1 algorithm. 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 lowercase letters, uppercase letters and numerals to convert a binary certificate into a printable form. You can copy and paste a certification request into a certification authority's web page, an e-mail that you send to the certification authority or a text editor and save the file on a management computer for later manual enrollment. You can copy and paste a certificate into an e-mail to send to friends or colleagues or you can copy and paste a certificate into a text editor and save the file on a management computer for later distribution (via floppy disk for example).

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 or generated by the UAG.
Subject
This field displays information that identifies the owner of the certificate, such as
Common Name (CN), Organizational Unit (OU), Organization (O), State (ST), 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.
“none” displays for a certification request.
Signature Algorithm
This field displays the type of algorithm that was used to sign the certificate. The UAG
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. “none” displays for a
certification request.
Valid To
This field displays the date that the certificate expires. The text displays in red and
includes an Expired! message if the certificate has expired. “none” displays for a
certification request.
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).
Subject Alternative
Name
This field displays the certificate owner‘s IP address (IP), domain name (DNS) or e-mail
address (EMAIL).
Key Usage
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.
Basic Constraint
This field displays general information about the certificate. For example, Subject
Type=CA means that this is a certification authority’s certificate and
“Path Length
Constraint=1” means that there can only be one certification authority in the
certificate’s path. This field does not display for a certification request.
MD5 Fingerprint
This is the certificate’s message digest that the UAG calculated using the MD5
algorithm.
SHA1 Fingerprint
This is the certificate’s message digest that the UAG calculated using the SHA1
algorithm.
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 lowercase letters, uppercase letters and
numerals to convert a binary certificate into a printable form.
You can copy and paste a certification request into a certification authority’s web page,
an e-mail that you send to the certification authority or a text editor and save the file on
a management computer for later manual enrollment.
You can copy and paste a certificate into an e-mail to send to friends or colleagues or
you can copy and paste a certificate into a text editor and save the file on a
management computer for later distribution (via floppy disk for example).
