I am trying to accomplish a TLS connection using the MQTT protocol. What I need are the following certificates:
Client private key
Trusted root CA certificates
All these files must be in .PEM format. According to my server domain it supports the CA-certificate from letsencrypt. How can I obtain this CA-certificate and can the Client certificate and Private key be derived from this CA certificate?
Hope someone can give me some clarity.
Thank you all in advance.
