The wolfSSL library is a lightweight SSL/TLS library written in ANSI C and targeted for embedded, RTOS, and resource-constrained environments - primarily because of its small size, speed, and feature set. wolfSSL brings trusted, military-grade security to connected commercial and military aircraft. Avionics developers now have a flexible, compact, economical, high-performance COTS solution for quickly delivering enhanced, secure communications that can be readily certified to DO-178. In addition, any of the FIPS 140-2 validated crypto algorithms can be used in DO 178 mode for combined FIPS 140-2/DO 178 consumption.
wolfSSL is commonly used in standard operating environments as well because of its royalty-free pricing and excellent cross platform support. wolfSSL supports industry standards up to the current TLS 1.3 and DTLS 1.2 levels, and is up to 20 times smaller than OpenSSL.
