Creating SSL keys for Postman Mock Server

I have created a mock server on postman. It gives me a HTTPS url to send request to the mock server. I want to generate SSL certificates for the mock server so that client can use those certificate while sending request to the mock server. How can I generate SSL server for the mock server?

You don’t need to generate any keys for your client. It should work as it is.

Since you are not the owner of the service, you can’t generate SSH keys.
