A certificate consists of two different Keys:
Master Key is generated by the Master and is incorporated into the text string sent to the
CA during a certificate request. It is unique to a particular request made on a specific
Master.
Public Key is part of the text string that is returned from the CA as part of an approved
SSL Server Certificate. This public key is based off the submitted Master key from the
original request.
Regenerating a previously requested and installed certificate invalidates that
certificate because the Master Key has been changed.
Server Certificate Entries (Cont.)
City/Location Name of the city where the certificate is used. This is an
alpha-numeric string (1 - 50 characters in length).
State/Province Name of the state or province where the certificate is used. This
is an alpha-numeric string (1 - 50 characters in length).
Country Name Provides a drop-down selection with a listing of currently
selectable countries.
Action Provides a drop-down selection with a listing of available
certificate options:
Display Certificate - Populates the Server Certificate fields with
the information from the certificate currently installed on the
Master. This action is used only to display the information
contained in the certificate on the target Master.
Create Request - Takes the information entered into the
previous fields and formats the certificate so it can be exported
to the external Certificate Authority (CA) for later receipt of an
SSL Certificate. This action is used to request a certificate
from an external source.
Self Generate Certificate - Takes the information entered into
the previous fields and generates its own SSL Certificate.
This action is used when no previous certificate has been
installed on the target Master, or a self-signed certificate is
desired.
Regenerate Certificate - Takes the information entered into the
previous fields and regenerates an SSL Certificate. This action
changes the Master Key.
This method of certificate generation is used to modify or
recreate a previously existing certificate already on the
Master.
OK/Cancel/Delete Press OK to accept any changes made within this tab and
incorporate the information into the target Master.
Press Cancel to void any changes made within this tab, disable
the security configuration session, void any changes made to
the Master, and return you to the empty Security tab.
If a certificate has been purchased from an external CA and then installed onto a
specific Master, DO NOT regenerate the certificate or alter its properties
(ex: bit length, city, etc.).
If the purchased certificate is regenerated, it becomes invalid.
