👉 Overview
👀 What ?
OpenSSL is a robust, commercial-grade, and full-featured toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. It also serves as a general-purpose cryptography library.
🧐 Why ?
OpenSSL is important because it provides secure communication over networks against eavesdropping. It is used widely in internet-based software to secure connections, and is a core component of many operating systems, applications, and embedded systems.
⛏️ How ?
To use OpenSSL, you need to install it on your system first. After the installation, you can use its command-line tool to generate a key pair, create a Certificate Signing Request (CSR), create a self-signed certificate, convert certificate formats, and other operations.
⏳ When ?
OpenSSL was first released in 1998 as a collaborative effort to develop a secure, commercial-grade, and open-source toolkit implementing SSL and TLS protocols.
⚙️ Technical Explanations
Under the hood, OpenSSL uses a variety of cryptographic algorithms such as AES, DES, RSA, DSA, Diffie Hellman, ECC, etc. It provides a rich API that allows developers to use these algorithms in their applications. OpenSSL also includes various command-line utilities for handling SSL certificates. It is written in C, and its architecture is based on a flexible and modular design. It follows the principle of 'least privilege' to provide robust security.
