Enabling encryption on mosquitto

To enable encryption on mosquitto, you need first to have certificates. You can buy them from a company that is issuing certificates or you can generate them yourself as self-sign certificates.

Installing the openssl package

First, verify that you have the openssl package installed and it has a newer version (1.0.2g), as seen in the following screenshot:

If you don't have openssl installed you need to install it first, using the following command:

sudo apt install openssl on Ubuntu

Or use the following command:

yum install openssl on CentOS/Redhat

Generating your own certificates

First go to /etc/mosquitto/certs and issue the following command:

sudo openssl req -x509 -newkey rsa:1024 -keyout ca.crt -out cert.crt -days 9999

You will then be invited to fill some details, as seen in the following screenshot, about the owner of the certificate, such as country of residence, state, company, city, email address, and the most important one is the Fully Qualified Domain Name...
