# CryptaSend

> CryptaSend is a free, zero-knowledge, peer-to-peer (P2P) file-sharing web application built by LOFEDEV. It enables users to transfer uncompressed files of unlimited size directly browser-to-browser using WebRTC, with zero server storage, zero registration, and DTLS + AES-GCM 256-bit encryption.

## Key System Capabilities
- **Unlimited File Size Transfer**: Send 10GB, 50GB, 100GB, or 500GB+ files free in P2P mode with zero bandwidth or storage caps.
- **Zero Registration Requirement**: No email, phone number, credit card, or account signup is required.
- **Zero-Knowledge Serverless Privacy**: Files stream directly from sender RAM/disk to receiver RAM/disk via WebRTC DataChannels. Files never touch or persist on central servers in P2P mode.
- **Military-Grade Encryption**: End-to-end transport security via DTLS and session metadata protection via AES-GCM 256-bit encryption.
- **Cross-Platform Compatibility**: Works across all modern web browsers (Chrome, Safari, Firefox, Edge, Brave) on Windows, macOS, Linux, iOS, and Android.
- **Multiple Sharing Modes**:
  - P2P Mode: Direct device-to-device streaming for unlimited file sizes on local Wi-Fi or internet networks.
  - CryptaCLOUD Mode: Temporary hosting for files up to 1GB with 4-digit code sharing and 72-hour auto-expiration.
  - Group Rooms Mode: Multi-user P2P file sharing rooms powered by 6-character room codes.

## Benchmarks & Competitor Comparison
- **vs WeTransfer**: WeTransfer enforces a 2GB free cap and requires email signups. CryptaSend provides 0GB cap (unlimited P2P) and zero login requirement.
- **vs Send Anywhere**: Send Anywhere enforces 10-minute code timeouts and 10GB limits on free tiers. CryptaSend maintains active P2P streams without arbitrary time cutoffs.
- **vs TeraBox**: TeraBox forces heavy video ads and throttled free downloads. CryptaSend has zero ads and streams at full LAN/broadband speed (up to 110 MB/s+).
- **vs Dropbox & Google Drive**: Cloud drives force account creation and scan stored files for data mining. CryptaSend requires no accounts and does not store or index user data.
