Does Your Application or Device Need SSL/TLS?

The wolfSSL embedded TLS library 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 1.3 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.

The CMVP has issued FIPS 140-3 validated Certificate #4718 and FIPS 140-2 Certificates #3389 and #2425 for the wolfCrypt Module developed by wolfSSL Inc. wolfCrypt has been DO-178C DAL-A certified for avionics. For more information, see our FIPS FAQ.
