Sharedrop
Sharedrop 是一个基于浏览器的文件传输应用，用于在设备之间直接传输文件，无需安装软件或注册账户。它使用 WebRTC 建立点对点（P2P）数据通道，允许在不同操作系统之间交换文件，而无需通过中央服务器路由流量。
该项目提供了本地和远程连接机制。它识别共享同一公共 IP 地址的活跃用户以实现即时本地设备发现，并允许通过唯一会话链接为不同网络上的用户创建私有共享房间。
所有传输均采用端到端加密，以确保只有预期的发送者和接收者才能访问数据。该系统在浏览器中将数据作为二进制 Blob 管理，以处理大文件传输。
Features
- WebRTC Data Channels - Establishes direct browser-to-browser data channels using WebRTC for serverless file transfers.
- Signaling Servers - Utilizes a signaling server to exchange connection metadata before establishing direct peer-to-peer links.
- End-to-End Encryption - Implements end-to-end encryption to ensure only the intended sender and receiver can access transferred files.
- WebRTC Transfer Tools - Moves files directly between peers using WebRTC for high speed and low latency.
- Browser-Based File Transfers - Provides the capability to send files directly between devices using a browser-based P2P connection.
- Browser-Based P2P Transfers - Sends files directly between browsers using WebRTC for peer-to-peer data transmission.
- Local Peer-to-Peer - Enables devices on the same local network to detect each other and exchange files.
- IP Address Discovery Tools - Automatically identifies available local peers by grouping users sharing the same public IP address.
- Local Network Discovery - Identifies and displays active users on the same public IP address to facilitate immediate transfers.
- Private Sharing Rooms - Creates secure temporary rooms for encrypted file sharing with specific users across different networks.
- Ephemeral Exchange Rooms - Generates unique identifiers to create private sharing rooms for users on different networks.
- Binary Blob Management - Uses binary blob management to handle large file transfers directly within the browser memory.
- Local File Sharing PWAs - Allows sending files between devices on the same network using a browser without central server uploads.
- File Sharing - Serverless file transfer between devices on the same network.
