Secure data sharing
Share verified data without the server ever reading it.
Raytio provides end-to-end encrypted data sharing between people and organisations. Data is encrypted on the sender's device and only ever decrypted on an authorised recipient's device - Raytio's servers hold only ciphertext. Teams can share access, and organisations can forward data onward, all without exposing keys to the server.
How it works
- A data provider submits information; sensitive fields are encrypted on their device with the recipient's public key before upload.
- The recipient decrypts on their own device - keys are unwrapped locally, never server-side.
- Adding a team member re-wraps the access key for that person's public key; revoking them deletes their wrapped copy without touching anyone else's access.
- Forwarding to another organisation re-wraps only the data's key for the destination - the data itself is never decrypted or re-encrypted in transit.
Why Raytio
Every share operation is public-key cryptography performed client-side - a server breach yields only ciphertext and wrapped keys.
Decryption keys derive from your password plus a device-bound secret - neither a phished password nor a stolen device alone can unlock your data.
Access is a wrapped key per person; removing a person removes their key, instantly, with no data churn.
Verified customers, protected data, and agents you can hold to account.
