OpenSSL is the ubiquitous, robust, full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is the cryptographic backbone of the modern internet, used by web servers (Apache, Nginx), databases, VPNs, and countless command-line utilities. Despite the emergence of alternatives like LibreSSL and BoringSSL, OpenSSL remains the industry standard. used by web servers (Apache
