IamNanjo / encrypted-chat-app

End-to-end encrypted realtime chat app made using Nuxt 3, Websockets and the Web Crypto API

Encrypted Chat App

This chat app uses end-to-end-encryption with RSA-OAEP. The encryption is done on the client using the Web Crypto API. The encrypted messages and public keys are saved on the server and they are then sent to users.

New chats and messages are sent to clients using Websockets. This means that only the new messages need to be decrypted and there will be no need to constantly poll the server for updates. This makes the chat app far more performant efficient.

New messages are fetched using polling. In a future update the app will use Websockets instead of polling for faster updates and less unnecessary requests. This will also allow only decrypting new messages instead of the whole list every time, making the app far more efficient.
