Building a Secure Chat Application with Asymmetric Encryption in Ruby
In a world where digital communication has become the cornerstone of our daily lives, the need for secure and private conversations has never been greater. This article explores the power of asymmetric encryption and guides developers on how to create a secure chat application using the Ruby programming language. The author emphasizes that no third-party services or additional libraries will be used, and everything will be built from scratch. Asymmetric encryption, unlike symmetric encryption, uses two distinct keys - a public key and a private key - providing an extra layer of protection for secure communication. The article takes readers through the core features of the app, starting with server creation using web sockets. The server is designed to handle incoming clients and broadcast messages to each one of them. The code examples and step-by-step instructions make it easy for developers to follow along and implement their own secure chat application.
