wolfSSL
wolfSSL is a lightweight, portable, and open-source SSL/TLS library written in C, designed for embedded systems, IoT devices, and resource-constrained environments. It provides secure communication protocols such as TLS 1.3, DTLS, and supports various cryptographic algorithms. The library is known for its small footprint, high performance, and compatibility with multiple operating systems and hardware platforms.
Developers should learn and use wolfSSL when building applications for embedded systems, IoT devices, or any environment with limited memory and processing power, as it offers a minimal code size without sacrificing security. It is ideal for use cases like secure firmware updates, device-to-cloud communication, and real-time operating systems where traditional TLS libraries are too heavy. Additionally, its open-source nature and commercial support make it suitable for both hobbyist projects and enterprise deployments.
