End-to-End Encryption

Privacy on the internet… is it possible?

Yes, it is. And this course will show you how.

End-to-end encryption isn’t optional anymore. It’s essential.

Contemporary news articles show how private data is routinely exposed, misused, and weaponized. If you’re building apps, handling user data, or simply value digital freedom, you need to know how to encrypt your data.

💡 What You’ll Learn

The course is designed to be hands-on, with a focus on building a real web application. You’ll learn:

Browser APIs — encrypt data before it leaves the browser
Asymmetric encryption (RSA) — Exchange secrets securely
Symmetric encryption (AES) — Fast, strong security
Device sync — Decrypt data on multiple devices
IndexedDB — store data locally

🛠 Build something real

By the end of the course, you will have built a real, functional web app that

only sends opaque blobs to the server
shows how to use encryption in the browser
manages keys in the browser
can synchronize and decrypt data on multiple devices

❓ Who Is This For?

Whether you’re a software engineer shipping production code, or an indie hacker who wants to protect their users, you’ll leave with the skills necessary to handle data securely.
