cmkSecretConfig
Specifies configuration information for a DataSync-managed secret, which includes the authentication token that DataSync uses to access a specific AzureBlob storage location, with a customer-managed KMS key.
When you include this parameter as part of a CreateLocationAzureBlob request, you provide only the KMS key ARN. DataSync uses this KMS key together with the authentication token you specify for SasConfiguration to create a DataSync-managed secret to store the location access credentials.
Make sure that DataSync has permission to access the KMS key that you specify. For more information, see Using a service-managed secret encrypted with a custom KMS key.
You can use either CmkSecretConfig (with SasConfiguration) or CustomSecretConfig (without SasConfiguration) to provide credentials for a CreateLocationAzureBlob request. Do not provide both parameters for the same request.
