Peertransfer

Abstract

1. Introduction

:package: • Send a file p2p and e2e encrypted in your browser using WebRTC.

2. Objective

:package: • Send a file p2p and e2e encrypted in your browser using WebRTC.

This project demonstrates how CSS can be applied to a real-world Cybersecurity & Ethical Hacking problem.

3. Key Features / Modules

• Data is sent directly peer-to-peer.
• Data is transferred using end-to-end encryption (due to WebRTC).
• The messages that are relayed by a server to initiate the p2p WebRTC connections are encrypted (to protect against IP leakages and man-in-the-middle attacks while initiating WebRTC).
