❌ Revoke Access

The owner of the file can revoke the access of an encrypted file that was shared by him previously, this code example demonstrates the same.

JS SDK

const revokeAccess = async () => {
  try {
    // CID of the encrypted file that you want to revoke access to
    // CID is generated by uploading a file with encryption
    // Only the owner of the file can revoke access to another wallet address
    const cid = 'YOUR_CID' // Example: "Qma7Na9sEdeM6aQeu6bUFW54HktNnW2k8g226VunXBhrn7";
    const publicKey = 'YOUR_PUBLIC_KEY' // Example: "0xa3c960b3ba29367ecbcaf1430452c6cd7516f588";
    const signedMessage = "SIGNATURE/JWT"
    const publicKeyUserB = ['RECEIVER_PUBLIC_KEY'] // Example: "0x487fc2fE07c593EAb555729c3DD6dF85020B5160";

    const revokeResponse = await lighthouse.revokeFileAccess(
      publicKey,
      publicKeyUserB,
      cid,
      signedMessage
    )
    console.log(revokeResponse)
    /* Sample Response
    {
      data: {
        cid: 'QmTsC1UxihvZYBcrA36DGpikiyR8ShosCcygKojHVdjpGd',
        revokeTo: [ '0x487fc2fE07c593EAb555729c3DD6dF85020B5160' ],
        status: 'Success'
      }
    }
    */
  } catch (error) {
    console.log(error)
  }
}
