# WiFiPlusPlus

> WiFiPlusPlus is an ultra-fast local Wi-Fi and peer-to-peer (P2P) file transfer platform for Android, PC, Mac, Linux, and Web Browsers. It transfers heavy files, 4K videos, folders, and APKs at up to 50 MB/s over hardware Wi-Fi Direct and local hotspot sockets with zero internet and zero mobile cellular data usage. For remote transfers, it provides secure, ephemeral peer-to-peer file streaming via 6-digit PIN room codes with zero permanent cloud storage and end-to-end encryption.

## Core Capabilities & Performance
- **50 MB/s Hardware Speed**: Uses device Wi-Fi Direct and SoftAP 5 GHz sockets for maximum local transfer throughput.
- **Zero Cloud Storage (100% Private)**: Files stream directly between devices. Zero files are stored, archived, or indexed on cloud servers.
- **No Internet or Cellular Data Required**: Local transfers operate completely offline, air-gapped without consuming mobile carrier data.
- **WhatsApp Web-Style Desktop Link**: Open `wifiplusplus.com/web` on a laptop or desktop browser, scan the QR code or enter the 6-digit code in the Android app to browse and download phone files at local gigabit speeds.
- **Worldwide P2P Live Share**: Share files over the internet using ephemeral 6-digit PIN codes with end-to-end encryption (AES-256-GCM) and chunked streaming.
- **Byte-Range Partial Resume Engine**: If a connection is interrupted during a multi-gigabyte transfer, transfers automatically resume from the last verified byte without starting over.
- **Unlimited File Size**: Direct binary socket streaming bypasses browser RAM limits, enabling transfer of massive files (10 GB+, 4K movies, raw archives).

## Technical Protocols & Architecture
- **Local Wi-Fi Direct & SoftAP**: Sender phone creates a localized Wi-Fi hotspot (192.168.43.1:8080). Receiver connects via air-gapped QR code containing SSID and ephemeral WPA2 key.
- **Desktop Web Connect**: Local HTTP server on port 8080 with tokenized REST endpoints (`/api/state`, `/api/download/:id`, `/api/upload`). Cloud relay facilitates initial handshake; byte transfer remains 100% local.
- **P2P Ephemeral Streaming**: Ephemeral rooms identified by 6-digit PINs. Web client streams chunks via ReadableStream with PBKDF2/AES-GCM encryption. Server memory relay discards chunks immediately upon consumption.
