OpenSSL Cryptography and SSL / TLS Binary Distributions

OpenSSL is a popular open-source software library that provides a robust, full-featured set of cryptographic functions and tools to secure communications over computer networks. It implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, which are widely used to encrypt data transmissions between web servers and clients, such as web browsers. OpenSSL provides a wide range of cryptographic functions, including symmetric encryption, public-key encryption, message digest and hash functions, digital signatures, and random number generation. It supports a large number of cryptographic algorithms, such as AES, RSA, SHA, and many others. In addition to cryptographic functions, OpenSSL also provides utilities for generating and managing digital certificates and keys, creating and verifying digital signatures, and performing SSL/TLS handshake and negotiation. OpenSSL is available various operating systems, including Linux, Windows, and macOS. It is used by many software applications (including FireDaemon Certify One, FireDaemon Fusion, and FireDaemon Lozenge) web servers, and security products, and is an important component of many security-related systems and services. We have made available our binary distributions of OpenSSL for Microsoft Windows for packaged as ZIP files or Windows installers. Our OpenSSL binary distributions can be used for free standalone or embedded in your own software projects or software products.
