End-to-End Encrypted Chat in Flutter

In a tutorial exploring the implementation of end-to-end encryption (E2EE) in a Stream Flutter chat application, the text details the process of securing messages so that only the sender and receiver have access, using a combination of public and private cryptographic keys. It explains how to generate these keys with the Web Cryptography API and describes the encryption and decryption processes using the AES-GCM algorithm. The tutorial guides users through building a chat feature, setting up channels and users, and preparing the app for encryption by storing users' public keys. It provides code snippets for encrypting messages before sending them to the server and decrypting them for display to the receiver, emphasizing the need for security considerations and the importance of consulting professionals when implementing such features in a production environment.
