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.  It 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, is up to 20 times smaller than OpenSSL, and offers progressive ciphers such as ChaCha20, Curve25519, NTRU, and Blake2b.  User benchmarking and feedback reports dramatically better performance when using wolfSSL over OpenSSL.

wolfSSL is powered by the wolfCrypt library. wolfCrypt is FIPS 140-2 Level 1 validated, with certificate #2425. For additional information, visit our FIPS FAQ page or contact fips@wolfssl.com.

wolfSSL is built for maximum portability, and is generally very easy to compile on new platforms.  If your desired platform is not listed under the supported operating environments, please contact wolfSSL.

wolfSSL supports the C programming language as a primary interface. It also supports several other host languages, including Java, PHP, Perl, and Python (through a SWIG interface). If you have interest in using wolfSSL in another programming language that it does not currently support, please contact wolfSSL at info@wolfssl.com.
