How does the encryption and sharing work?
Encryption and sharing is enabled by a combination of asymmetric and symmetric cryptography run by the frontend in the browser. No plaintext data is stored on the backend. Frontend and backend code can be audited and verified.
User registration
After registration a public key pair is created for the user in the frontend. The public key is stored in the backend for each registered user, together with their name.
Document Upload
When you upload a document, the frontend creates a symmetric secret key in the browser. This symmetric key is then encrypted with the public key of the user who requested the document.
Document Access
The frontend of a registered user can get the encrypted file together with the encrypted key from the backend canister. Using the private key stored in the browser, the frontend can decrypt the document and process it.
Protected by Cryptography
Standard browser cryptography libraries are used for key generation, encryption and decryption. Your private key remains on your device, only encrypted data is stored in the backend.
