## Description

Sharedrop is a browser-based file drop application for transferring files directly between devices without requiring software installation or account registration. It uses WebRTC to establish peer-to-peer data channels, allowing files to be exchanged between different operating systems without routing traffic through a central server.

The project provides mechanisms for both local and remote connectivity. It identifies active users sharing the same public IP address for immediate local device discovery and allows the creation of private sharing rooms via unique session links for users on different networks.

All transfers are secured with end-to-end encryption to ensure only the intended sender and receiver can access the data. The system manages data as binary blobs within the browser to handle large file transfers.
