Step 4: Update Device’s Trusted Certificate Store
For the device to trust a whole chain of certificates you need to combine the contents of the root.crt and ca.crt certificates into a single text file (using a text editor).
|
➢
|
To update the device with the new certificate: |
|
1.
|
Open the root.crt file (using a text-based editor, e.g., Notepad). |
|
2.
|
Open the ca.crt file (using a text-based editor, e.g., Notepad). |
|
3.
|
Copy the content of the ca.crt file and paste it into the root.crt file above the existing content. |
Below is an example of two certificate files combined (the file "ca2.crt" and the "root.crt") where the ca2.crt file contents are pasted above the root.crt file contents:

The maximum supported size of the combined file of trusted chain of certificates is 100,000 bytes (including the certificate's headers).
|
4.
|
Save the combined content to a file named "chain.pem" and close the file. |
|
5.
|
Open the Certificates page and upload chain.pem file using the 'Trusted Root Certificate Store' field. |
