Step 2: Receive the New Certificates from the CA
You will receive the following files from the Certificate Authority (CA):
|
■
|
Your (device) certificate – rename this file to "device.crt" |
|
■
|
Root certificate – rename this file to "root.crt" |
|
■
|
Intermediate CA certificates (if such files exist) – rename these files to "ca1.crt", "ca2.crt" etc. |
Save the signed certificate to a file (e.g., device.crt). Make sure that all certificates are in PEM format and appear as follows:
