ImageSecureSend

About ImageSecureSend

A secure, end-to-end encrypted photo transfer app designed for environments where data privacy is paramount. Photos never leave your device unencrypted, and only the intended recipient can decrypt them — no middleman, not even the server, ever has access.

Tech Stack

• Frontend: Vanilla HTML, CSS, JavaScript (no frameworks)
• Transport: WebRTC peer-to-peer data channels
• Encryption: ECDH key exchange + AES-GCM (Web Crypto API)
• Signaling: Express.js server (SDP relay only)
• QR Codes: qrcode.js / jsQR
• TURN Relay: coturn (fallback when direct P2P fails)

Security

• Photos are encrypted before leaving your device
• The server only relays connection metadata (SDP)
• Keys are generated fresh for each session
• Fingerprint verification prevents MITM attacks
