How To Secure a Vite-Powered React App With Seald End-to-End Encryption
Blog post from Stream
This comprehensive tutorial details the implementation of end-to-end encryption (E2EE) in a chat application by integrating Seald's encryption service with Stream's Chat SDK. The objective is to ensure that chat conversations are only accessible to channel members, preventing unauthorized server-side access and enhancing user privacy. The guide walks through creating accounts on Stream and Seald, setting up a Next.js app, and configuring the Stream Chat SDK for basic messaging functionality. It then introduces Seald's SDK for encryption and decryption processes, explaining the initialization of Seald identities and encryption sessions, and how to handle message encryption and decryption within the chat interface. The tutorial concludes by integrating these components into a React chat app, demonstrating how to encrypt messages before sending and decrypt them upon receipt, thereby creating a secure chat environment akin to WhatsApp Web. The project is hosted on GitHub, and users are encouraged to explore further functionalities of the chat and encryption SDKs.
