wolfssl
A lightweight, portable TLS/SSL library written in ANSI C for embedded systems, RTOS, and cloud applications.
What is wolfssl?
wolfSSL is a lightweight, portable SSL/TLS library written in ANSI C, designed for embedded systems, RTOS, and resource-constrained environments. It provides secure communication with support for up to TLS 1.3 and DTLS 1.3, offering a small footprint and high performance compared to alternatives like OpenSSL.
Embedded systems engineers, IoT developers, and anyone needing a small, fast, and portable TLS/SSL library for constrained environments or applications requiring FIPS-validated cryptography.
Developers choose wolfSSL for its minimal size, superior performance, and comprehensive support for modern cryptographic standards, including post-quantum algorithms, all while being royalty-free and offering an OpenSSL-compatible API for easy integration.
Overview
The wolfSSL library is a small, fast, portable implementation of TLS/SSL for embedded devices to the cloud. wolfSSL supports up to TLS 1.3 and DTLS 1.3! Update to wolfSSL 5.9.1 for the latest CVE fixes.
