A real-time chat application built with Node.js and Socket.io that provides secure message encryption and user authorization.

Encryption

Messages exchanged between users are encrypted using a unique key for each conversation. The encryption process ensures that messages are secure and private. The key for encryption is generated based on the users involved in the conversation.

• We have a key pre declared for everyone while registering. Our encryption is the combination of the two keys plus one public key.
• User A Key: "poiuyt"
• User B Key: "mnbvc"
• Public Key: "KEY" Hence the key for our encryption will be: "poiuytmnbvcKEY", So that we can have a unique key for each conversation.
