What is OpenSSL?

OpenSSL is an open-source cryptography library and command-line toolkit that implements the SSL and TLS protocols for securing network communications. It is used by web servers, operating systems, and countless applications to encrypt connections and manage X.509 certificates. The project is maintained by the OpenSSL Software Foundation and is one of the most widely deployed cryptographic libraries in the world.
