Send to Contact flow

End-to-end encrypted transfer using decentralized keys

1 Select a contact
Pick a contact whose identity code you added. A green check means their encryption key is ready.
2 Encrypt with X25519
The AES file key is encrypted with your contact's public key (ECIES). The link alone can no longer decrypt the file.
3 Send securely
Send encrypted file

Only your contact can decrypt this file.

Private by construction

Local AES-256-GCM

Files are encrypted in your browser before anything leaves your device. Decryption keys live in the URL fragment or your contact's key — never on a server.

Direct P2P

One-time codes and WebRTC DataChannel for direct transfers. Large files never touch a middleman; Iroh v1 is prepared for verified transport.

Sovereign identity

No accounts, no KYC. Pseudonymous keys generated locally; optional Holochain DHT publication so people can find you by hashed contact.
