Step 1: Create the server's certificate authority list

Create the certificate authority list and add the root certificate authority certificate.

Create the server's Certificate Authority List:

$ openssl x509 -in MyRootCA.crt -text >> ServerCAList.pem

As the server trusts only the Root Certificate Authority, the list contains only that one certificate authority; all other certificates that were trusted by the Root Certificate Authority will also be considered as trusted by the server.

In the next step we register the server's certificate authority list, Step 2: Register the server as a Web service in the GAS.
