SSL Server Certificate Creation Procedures
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.
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.
