Digital Registered Sending
How does CarryOn work?
Encryption in browser
Your document is encrypted with AES-256 in your browser before it leaves.
Encrypted data to IPFS
Only encrypted data goes to IPFS. The recipient gets a link—without the key.
Key shared separately
The key is shared via a separate channel (WhatsApp, SMS, etc.). Never through SIIS.
Accept or decline
The recipient chooses: accept or decline. Both actions are timestamped and stored on IPFS.
Dual receipt system
Proof for both sender and recipient. Each gets a verifiable receipt.
