The original device CA key is saved when a new key is uploaded. It can be restored at any time
using the
Restore CA Key button in the Authentication tab in DashBoard. This is illustrated in
Figure 12.
Figure 13 shows how to obtain the device’s internal CA certificate for Step 2. No password is
needed because the certificate does not need to be kept confidential. Use the process shown in
Figure 9 to install the CA certificate in each Cobalt device.
In Step 3 a CSR is generated for each device and signed by the CA device. The CSR generation
for Cobalt devices is covered in the section entitled “Obtaining a CSR for the Built-In Keys”.
Figure 14 shows the process of signing a certificate, which is done through the web interface.
