Cacert.pem data - where should I get from?

Technical Subjects Open Solution

First, I would like to communicate with MQTT broker from M66 without SSL option. I want an example broker configuration. I want to publish and see the data in broker. Then I want to go for ‘with SSL’ option and I need the data for all certificates to write in RAM. Anybody can help me?
