AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Disconnects the custom key store from its backing key store. This operation disconnects an CloudHSM key store from its associated CloudHSM cluster or disconnects an external key store from the external key store proxy that communicates with your external key manager.

This operation is part of the custom key stores feature in KMS, which combines the convenience and extensive integration of KMS with the isolation and control of a key store that you own and manage.

While a custom key store is disconnected, you can manage the custom key store and its KMS keys, but you cannot create or use its KMS keys. You can reconnect the custom key store at any time.

While a custom key store is disconnected, all attempts to create KMS keys in the custom key store or to use existing KMS keys in cryptographic operations will fail. This action can prevent users from storing and accessing sensitive data.

When you disconnect a custom key store, its ConnectionState changes to Disconnected. To find the connection state of a custom key store, use the DescribeCustomKeyStores operation. To reconnect a custom key store, use the ConnectCustomKeyStore operation.

If the operation succeeds, it returns a JSON object with no properties.

Cross-account use: No. You cannot perform this operation on a custom key store in a different Amazon Web Services account.

Required permissions: kms:DisconnectCustomKeyStore (IAM policy)

Eventual consistency: The KMS API follows an eventual consistency model. For more information, see KMS eventual consistency.

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to DisconnectCustomKeyStoreAsync.

Namespace: Amazon.KeyManagementService

Syntax

C#
public virtual DisconnectCustomKeyStoreResponse DisconnectCustomKeyStore(
         DisconnectCustomKeyStoreRequest request
)

Parameters

request
Type: Amazon.KeyManagementService.Model.DisconnectCustomKeyStoreRequest

Container for the necessary parameters to execute the DisconnectCustomKeyStore service method.

Return Value


The response from the DisconnectCustomKeyStore service method, as returned by KeyManagementService.

Exceptions

ExceptionCondition
CustomKeyStoreInvalidStateException The request was rejected because of the ConnectionState of the custom key store. To get the ConnectionState of a custom key store, use the DescribeCustomKeyStores operation. This exception is thrown under the following conditions: You requested the ConnectCustomKeyStore operation on a custom key store with a ConnectionState of DISCONNECTING or FAILED. This operation is valid for all other ConnectionState values. To reconnect a custom key store in a FAILED state, disconnect it (DisconnectCustomKeyStore), then connect it (ConnectCustomKeyStore). You requested the CreateKey operation in a custom key store that is not connected. This operations is valid only when the custom key store ConnectionState is CONNECTED. You requested the DisconnectCustomKeyStore operation on a custom key store with a ConnectionState of DISCONNECTING or DISCONNECTED. This operation is valid for all other ConnectionState values. You requested the UpdateCustomKeyStore or DeleteCustomKeyStore operation on a custom key store that is not disconnected. This operation is valid only when the custom key store ConnectionState is DISCONNECTED. You requested the GenerateRandom operation in an CloudHSM key store that is not connected. This operation is valid only when the CloudHSM key store ConnectionState is CONNECTED.
CustomKeyStoreNotFoundException The request was rejected because KMS cannot find a custom key store with the specified key store name or ID.
KMSInternalException The request was rejected because an internal exception occurred. The request can be retried.

Examples

This example disconnects an AWS KMS custom key store from its backing key store. For an AWS CloudHSM key store, it disconnects the key store from its AWS CloudHSM cluster. For an external key store, it disconnects the key store from the external key store proxy that communicates with your external key manager. This operation doesn't return any data. To verify that the custom key store is disconnected, use the DescribeCustomKeyStores operation.

To disconnect a custom key store from its CloudHSM cluster


var client = new AmazonKeyManagementServiceClient();
var response = client.DisconnectCustomKeyStore(new DisconnectCustomKeyStoreRequest 
{
    CustomKeyStoreId = "cks-1234567890abcdef0" // The ID of the custom key store.
});
