Remarks

There are no keys available for attestation. This error is returned only on devices that rely solely on remotely-provisioned keys (see Remote Key Provisioning).

On such a device, if the caller requests key generation and includes an attestation challenge (indicating key attestation is required), the error will be returned in one of the following cases: <ul> <li>The pool of remotely-provisioned keys has been exhausted.</li> <li>The device is not registered with the key provisioning server.</li> </ul>

This error is a transient one if the pool of remotely-provisioned keys has been exhausted. However, if the device is not registered with the server, or the key provisioning server refuses key issuance, this is a permanent error.
