Open Cryptochat - A Tutorial
Cryptography is important. Without encryption, the internet as we know it would not be possible - data sent online would be as vulnerable to interception as a message shouted across a crowded room. Cryptography is also a major topic in current events, increasingly playing a central role in law enforcement investigations and government legislation.
Encryption is an invaluable tool for journalists, activists, nation-states, businesses, and everyday people who need to protect their data from the ever-present threat of hackers, spies, and advertising agencies.
An understanding of how to utilize strong encryption is essential for modern software development. We will not be delving much into the underlying math and theory of cryptography for this tutorial; instead, the focus will be on how to harness these techniques for your own applications.
In this tutorial, we will walk through the basic concepts and implementation of an end-to-end 2048-bit RSA encrypted messenger. We'll be utilizing Vue.js for coordinating the frontend functionality along with a Node.js backend using Socket.io for sending messages between users.
