When transmitting or storing user data, especially private conversations, it’s essential to consider employing cryptographic techniques to ensure privacy.

By reading this tutorial, you’ll learn how end-to-end encrypt data in web applications using nothing but JavaScript and the Web Crypto API, which is a native browser API.

Please note that this tutorial is very basic and strictly educational, may contain simplifications, and rolling your own encryption protocol is not advisable. The algorithms used can contain certain ‘gotchas’ if not employed properly with the help of security professionals

You can also find the full project in this GitHub repo if you happen to get lost. And if you have any questions, feel free to reach out to me on Twitter :).
