The wolfCrypt embedded cryptography engine is a lightweight cryptography library targeted for embedded, RTOS, and resource constrained environments primarily because of its small size, speed, and portability. wolfCrypt supports the most popular algorithms and ciphers as well as progressive ones such as ChaCha20, Curve25519, NTRU, and SHA-3. wolfCrypt is stable, production-ready, and backed by an excellent support team. A version of the wolfCrypt cryptography library has been FIPS 140-2 validated (Certificates #2425 and #3389).
