What is OpenSSL? SSL Explained

What is OpenSSL? To understand OpenSSL, you also need to understand its two broad purposes. First, it serves as a toolkit for Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. Second, it is a general purpose cryptography library for applications securing communications taking place over computer networks. This is essential in revealing identities of parties communicating between two points on the internet and guarding systems against eavesdropping. OpenSSL is initially written in C but has wrappers (programs or data that frames other programs or data so that they can run smoothly) supporting numerous other languages. It has wide use in web servers with over 60% web servers having them in 2017.   The OpenSSL library holds tools essential for the following tasks: Generating private keys for RSA (Rivest-Shamir-Adleman, a public key cryptosystem) Generating Certificate Signing Request (CSRs) Performing encryption/decryption as well as managing certificates   Therefore, OpenSSL can broadly be described as a platform that provides an array of utility functions as well as implementing basic cryptographic functions. This makes it an important element of internet security and cryptography.   A brief history of OpenSSL There was the need for tools that could be used for encrypting code…
