Building secure applications requires more than just adding encryption. Through live demos and real-world examples, we'll explore how to properly implement security features like end-to-end encryption, perfect forward secrecy, and secure device migration. You'll see how to protect both data and metadata, at rest and in transit, and learn about the common pitfalls that can compromise seemingly secure systems.

Using a chat application as our example, we'll walk through the evolution from basic encryption to a robust security system. We'll examine how real-world applications handle key management, protect against traffic analysis, and manage secure device enrollment. You'll learn the architectural patterns that make applications truly secure at scale.

Whether you're building a messenger, a document store, or any application that needs to protect user data, you'll leave with practical knowledge of how to implement encryption correctly and make informed security decisions in your own projects.
