NexusWire
A modern communication platform concept prioritizing privacy. NexusWire offers instant messaging and group chat functionality in a clean, distraction-free interface.
A real-time messaging application implementing End-to-End Encryption (E2EE) using the Signal Protocol. The server acts as a blind courier for encrypted messages, ensuring conversations are private and secure from eavesdropping.
The Challenge
Building a chat app is a rite of passage, but building a secure one is a discipline. The challenge was ensuring that messages were not just delivered fast, but were mathematically secure from prying eyes, including the server itself.
The Solution
I implemented End-to-End Encryption (E2EE) using an implementation of the Signal Protocol. Messages are encrypted on the sender's device using the recipient's public key and can only be decrypted on the recipient's device with their private key. The server acts merely as a blind courier, unable to read the content of the messages it transports.
