Linux MQTT OpenSSL

Linux is a free and open-source operating system that is widely used in servers, desktops, and mobile devices.

MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol that is designed for IoT (Internet of Things) devices. It enables devices to communicate with each other and with cloud-based systems in a reliable and efficient way.

OpenSSL is a free and open-source software library that provides cryptographic functions for secure communication over the internet. It is widely used in web servers, VPNs, and other applications that require secure data transfer.

In the context of IoT, MQTT can be secured using SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocols, which are implemented using OpenSSL. This ensures that data transferred between devices and cloud-based systems is encrypted and secure.
