External Certificate Authority” later in this document. The CA Selection configuration item can
choose between the local CA and the user-supplied CA. Note that selecting User-Supplied CA
Certificate can only be done after a certificate is actually uploaded.
The 9992-ENC implements a blocked device list. This is a list of devices which have proper
credentials (i.e., a certificate signed by the trusted CA) but should not be allowed to connect.
Devices are identified by their
Common Name (CN)
. Section “Creating a Blacklist” later in this
manual provides more detail on this process.
If you made any changes to the above parameters, these changes only take effect after you click
on the
Apply button. Clicking on the Cancel button reverts the changes.
If you are using the built-in CA in the 9992-ENC, it is important to back up its CA key. This
section of the GUI provides this functionality:
Clicking on the Save button will generate a file called CA_KEY.BIN with the device’s internal
CA key. This file is encrypted and uses a proprietary format; it is not compatible with any third-
party application.
If you need to restore a saved CA key to another Cobalt device, use the standard DashBoard
upload function, available at the bottom of any tab:
Once the file is uploaded and validated, it is automatically installed as the device’s CA key. A
CA certificate is automatically generated to match this key, and can be downloaded through the
web interface. An overview of the process can be found in the section entitle “Authenticating
Remote Devices” later in this manual.
If you uploaded a new CA key to the 9992-ENC but later decide to revert to the original built-in
key, this can be done simply by clicking on this button:
