  • pwfile is managed by mosquitto_passwd.
  • Two methods to support TLS:
    • You can get free TLS certificates from letsencrypt, capath is needed.
    • Self-signed TLS keys can be generated by openssl, cafile is needed.

It is important to use different certificate subject parameters for your self-signed CA, server and clients.
