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 default self-signed
certificate on the P-660HWP-Dx that the P-660HWP-Dx uses to sign the
trusted remote host certificates.
Signature Algorithm This field displays the type of algorithm that the P-660HWP-Dx used to sign the
certificate, which is rsa-pkcs1-sha1 (RSA public-private key encryption
algorithm and the SHA1 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 P-660HWP-Dx uses RSA encryption) and the length
of the key set in bits (1024 bits for example).
Subject Alternative
Name
This field displays the certificate’s 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.
MD5 Fingerprint This is the certificate’s message digest that the P-660HWP-Dx calculated
using the MD5 algorithm. The P-660HWP-Dx uses one of its own self-signed
certificates to sign the imported trusted remote host certificates. This changes
the fingerprint value displayed here (so it does not match the original). See
Section 13.3 on page 36 for how to verify a remote host’s certificate before you
import it into the P-660HWP-Dx.
SHA1 Fingerprint This is the certificate’s message digest that the P-660HWP-Dx calculated
using the SHA1 algorithm. The P-660HWP-Dx uses one of its own self-signed
certificates to sign the imported trusted remote host certificates. This changes
the fingerprint value displayed here (so it does not match the original). See
Section 13.3 on page 36 for how to verify a remote host’s certificate before you
import it into the P-660HWP-Dx.
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 64 ASCII characters to convert the
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).
Back Click Back to go to the previous screen
Export Click Export to export a file containing the details of your certificate.
Apply Click Apply to save your changes back to the P-660HWP-Dx. You can only
change the name of the certificate.
Cancel Click Cancel to quit configuring this screen and return to the Trusted Remote
Hosts screen.
