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.
