I need help on secure communication.

Hello all, I need help on secure communication. If any of you happen to know which library for mqtt-s with root ca, client certificate and client key? Have to use esp32 and w5500, not wifi.
Solution:
@wafa_ath Make use of OpenSSL to create your server certificate,the certificate will be signed by CA. Then..try as well to configure the MQTT broker to use the server certificate and private key. Check out on these points, l believe they will really be of help to you....
