NetLinx Security and Web Server

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.

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.
