🛡️ Security & Zero-Trust Model

🔒

Client-Side Hardware Encryption

Files are encrypted in your browser using AES-256-GCM before any bytes leave your device. The server is a blind mailman and never sees unencrypted file content. Not even filenames are known.

🔑

PBKDF2 Key Derivation

The 256-bit encryption key is derived using SHA256 and a cryptographically secure 16-byte random salt, fully compatible with the Android app DirectSend.

⚡

High-Speed Piped Streaming

Real-time memory pipe with zero disk footprint in Live Relay mode, or ephemeral 1-hour encrypted cloud staging that automatically deletes files the moment they are downloaded.

📱

Cross-Platform Interoperability

Seamlessly transfer files between Android phones, PCs, Macs, and Linux browsers.
