Mbed TLS
Mbed TLS is an open-source, portable SSL/TLS library written in C, designed for embedded systems and IoT devices. It provides cryptographic primitives, X.509 certificate handling, and SSL/TLS protocol implementations with a focus on small code size and low memory usage. It is widely used to secure network communications in resource-constrained environments.
Developers should learn Mbed TLS when building secure applications for embedded systems, IoT devices, or any environment with limited resources, as it offers a lightweight alternative to larger libraries like OpenSSL. It is essential for implementing TLS/SSL encryption, authentication, and data integrity in scenarios such as secure firmware updates, IoT device-to-cloud communication, and industrial control systems where performance and footprint are critical.
