TLSv1.3 capable SSL and crypto library
The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v3) and Transport Layer Security (TLS v1, v1.1, v1.2, v1.3) protocols with full-strength cryptography world-wide. The project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the OpenSSL tookit and its related documentation. OpenSSL is based on the excellent SSLeay library developed by Eric A. Young and Tim J. Hudson. The OpenSSL toolkit is licensed under an Apache-style licence, which basically means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions.
