Does your Application or Device Need SSL/TLS?


The wolfSSL embedded SSL library (formerly CyaSSL) is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set. It works seamlessly in desktop, enterprise, and cloud environments as well. wolfSSL supports industry standards up to the current TLS 1.2 and DTLS 1.2, is up to 20 times smaller than OpenSSL, offers a simple API, an OpenSSL compatibility layer, OCSP and CRL support, is backed by the robust wolfCrypt cryptography library, and much more.


wolfSSL relies on the soon-to-be FIPS 140-2 validated wolfCrypt library for all cryptographic functionality.  For more information, see our FIPS FAQ.

Providing secure communication for IoT, smart grid, connected home, automobiles, routers, applications, games, IP, mobile phones, the cloud, and more.
