Revoke file access

In this tutorial you will learn how to use Arcana Storage SDK and revoke file access for a file that was earlier uploaded to Arcana Store and shared by the current dApp user.

Prerequisites

  • Make sure your dApp is integrated with Arcana Storage SDK
  • You need to have access to the target user's wallet address for authenticating and revoking file sharing permissions
  • The DID of the file is required in order to revoke access and identify it uniquely on the Arcana Store
  • The code in the steps section below refers to StorageProvider and Access objects initialized during Storage SDK integration:
import { StorageProvider } from '@arcana/storage/dist/standalone/storage.umd';

dAppStorageProvider = new StorageProvider({
appId: ARCANA_APP_ID,
provider: window.ethereum,
email: user_email_string,
});

const Access = new dAppStorageProvider.getAccess();

Revoke file access

// did: DID of file from which access is removed
// address: Address of the user who's access is getting revoked
Access.revoke(did, address);

What's Next?

You can also change file ownership using Storage SDK.

If you are using Storage SDK with a third party wallet, you can also consider integrating with Arcana Auth SDK to ensure the privacy of your data by encrypting data before uploading and decrypting data after download.
