SSL Certificate Options
There are three SSL Certificate options, presented as links along the bottom of this page:
Creating an SSL Server Certificate
Initially, a NetLinx Master is not equipped with any installed certificates. In order to prepare a Master for later use with
"CA" (officially issued) server certificates, it is necessary to:
First create a self-generated certificate which is automatically installed onto the Master.
Secondly, enable the SSL feature from the Enable Security page. Enabling SSL security after the
certificate has been self-generated insures that the target Master is utilizing a secure connection during the
process of importing a CA server certificate over the web.
1. Click the Create SSL Certificate link (under SSL Certificate Options) to access the Create SSL Certificate window
(FIG. 54).
2. Fill out the information in this window, according to the descriptions in the SSL Certificate Entries section below.
3. Click Create SSL Certificate to update the Master with the information entered on this page. This process can take
several minutes.
SSL Certificate Options
Create SSL Certificate: Opens the Create SSL Certificate window where you can create a self-generated SSL
certificate.
Note: A self-generated certificate has lower security than an external CA (officially
issued) generated certificate.
Export SSL Certificate Request: Takes the user to the Server Certificate page where they can view a previously created
certificate.
An authorized user can also copy the raw text from a generated Certificate request into
their clipboard and then send it to the CA.
Import SSL Certificate: Takes the user to the Import Certificate page where they can import and paste the raw
text from a CA issued Certificate.
A certificate consists of two different Keys:
The 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. Note that regenerating a previously requested and installed
certificate invalidates that certificate because the Master Key has been changed.
The 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.
