Elevate Programming

In today’s digital landscape, securing data is paramount. Whether you’re building web applications, managing servers, or developing software that handles sensitive information, understanding cryptography is essential. OpenSSL is a powerful toolkit that software engineers can leverage for a variety of cryptographic functions. In this blog, we’ll explore what OpenSSL is, its core functionalities, and how you can effectively use it in your projects. What is OpenSSL? OpenSSL is an open-source implementation of the SSL and TLS protocols. It provides libraries for secure communication and a suite of command-line tools for performing various cryptographic operations, such as encryption, decryption, certificate management, and generating keys. Its versatility makes it a staple for software engineers and system administrators alike. Core Features of OpenSSL Encryption and Decryption : OpenSSL allows you to encrypt and decrypt files and data using various algorithms, includin...

JavaScript is single threaded language.  Synchronous programming is execution of functions in order. Asynchronous programming is executing a long running process outside the main thread. It does not block code execution on main thread. Although it is achieved usually by running asynchronous function on separate thread. Though javascript is a single threaded language it supports aysnchronous behaviour, to understand how we need to understand JS runtime.
