WolfSSL
wolfSSL is a small, portable, embedded SSL/TLS library targeted for use by embedded systems developers. It is an open source implementation of TLS (SSL 3.0, TLS 1.0, 1.1, 1.2, 1.3, and DTLS 1.0, 1.2, and 1.3) written in the C programming language. It includes SSL/TLS client libraries and an SSL/TLS server implementation as well as support for multiple APIs, including those defined by SSL and TLS. wolfSSL also includes an OpenSSL compatibility interface with the most commonly used OpenSSL functions.[4][5] PlatformswolfSSL is currently available for Microsoft Windows, Linux, macOS, Solaris, ESP32, ESP8266, Threadx, VxWorks, FreeBSD, NetBSD, OpenBSD, embedded Linux, Yocto Project, OpenEmbedded, WinCE, Haiku, OpenWrt, iPhone, Android, Wii, and GameCube through DevKitPro support, QNX, MontaVista, Tron variants, NonStop OS, OpenCL, Micrium's MicroC/OS-II, FreeRTOS, SafeRTOS, Freescale MQX, Nucleus, TinyOS, TI-RTOS, HP-UX, uTasker, uT-kernel, embOS, INtime, mbed, RIOT, CMSIS-RTOS, FROSTED, Green Hills INTEGRITY, Keil RTX, TOPPERS, PetaLinux, Apache Mynewt, and PikeOS.[6] HistoryThe genesis of wolfSSL dates to 2004. OpenSSL was available at the time, and was dual licensed under the OpenSSL License and the SSLeay license.[7] yaSSL, alternatively, was developed and dual-licensed under both a commercial license and the GPL.[8] yaSSL offered a more modern API, commercial style developer support and was complete with an OpenSSL compatibility layer.[4] The first major user of wolfSSL/CyaSSL/yaSSL was MySQL.[9] Through bundling with MySQL, yaSSL has achieved extremely high distribution volumes in the millions. In February 2019, Daniel Stenberg, the creator of cURL, was hired by the wolfSSL project to work on cURL.[10] ProtocolsThe wolfSSL lightweight SSL library implements the following protocols:[11]
Protocol Notes:
AlgorithmswolfSSL uses the following cryptography libraries: wolfCryptBy default, wolfSSL uses the cryptographic services provided by wolfCrypt.[13] wolfCrypt Provides RSA, ECC, DSS, Diffie–Hellman, EDH, NTRU (deprecated and removed), DES, Triple DES, AES (CBC, CTR, CCM, GCM), Camellia, IDEA, ARC4, HC-128, ChaCha20, MD2, MD4, MD5, SHA-1, SHA-2, SHA-3, BLAKE2, RIPEMD-160, Poly1305, Random Number Generation, Large Integer support, base 16/64 encoding/decoding, and post-quantum cryptographic algorithms: ML-KEM (certified under FIPS 203) and ML-DSA (certified under FIPS 204). wolfCrypt also includes support for the recent X25519 and Ed25519 algorithms. wolfCrypt acts as a back-end crypto implementation for several popular software packages and libraries, including MIT Kerberos[14] (where it can be enabled using a build option). NTRUCyaSSL+ includes NTRU[15] public key encryption. The addition of NTRU in CyaSSL+ was a result of the partnership between yaSSL and Security Innovation.[15] NTRU works well in mobile and embedded environments due to the reduced bit size needed to provide the same security as other public key systems. In addition, it's not known to be vulnerable to quantum attacks. Several cipher suites utilizing NTRU are available with CyaSSL+ including AES-256, RC4, and HC-128.
