P-792H v2 User's Guide
DESCRIPTION
This field displays the X.509 version number.
This field displays the certificate's identification number given by the
certification authority.
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).
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.
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.
This field displays the type of algorithm that was used to generate the
certificate's key pair (the P-792H v2 uses RSA encryption) and the
length of the key set in bits (1024 bits for example).
This is the certificate's message digest that the P-792H v2 calculated
using the MD5 algorithm. You can use this value to verify with the
certification authority (over the phone for example) that this is
actually their certificate.
This is the certificate's message digest that the P-792H v2 calculated
using the SHA1 algorithm. You can use this value to verify with the
certification authority (over the phone for example) that this is
actually their certificate.
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).

Click this to save your changes. You can only change the name and/or
set whether or not you want the P-792H v2 to check the CRL that the
certification authority issues before trusting a certificate issued by the
certification authority.
