Notes

---

Implemented

1. Diffie Hellman Key Exchange - A cool way to end up with private keys. The algorithm needs big primes to be secure, it was was way more fun than coding a PKI.

2. Standalone Mocha tests - npm install && npm test

3. Secure messaging - The users for now are ["You", "Me"] and they are in each other's contact list

4. File transfer - Transfers files using socketio streams. The test transfers a sample 1.8 mb

Not Done

1. Angular frontend.
2. iOS frontend.
3. SSL - (Easy should have done this :( )

I will be taking an extra week to finish the other 3 features.
