DeleteCustomKeyStore

Deletes a custom key store. This operation does not affect any backing elements of the custom key store. It does not delete the AWS CloudHSM cluster that is associated with an AWS CloudHSM key store, or affect any users or keys in the cluster. For an external key store, it does not affect the external key store proxy, external key manager, or any external keys.

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

The custom key store that you delete cannot contain any KMS keys. Before deleting the key store, verify that you will never need to use any of the KMS keys in the key store for any cryptographic operations. Then, use ScheduleKeyDeletion to delete the KMS keys from the key store. After the required waiting period expires and all KMS keys are deleted from the custom key store, use DisconnectCustomKeyStore to disconnect the key store from AWS KMS. Then, you can delete the custom key store.

For keys in an AWS CloudHSM key store, the ScheduleKeyDeletion operation makes a best effort to delete the key material from the associated cluster. However, you might need to manually delete the orphaned key material from the cluster and its backups. AWS KMS never creates, manages, or deletes cryptographic keys in the external key manager associated with an external key store. You must manage them using your external key manager tools.

Instead of deleting the custom key store, consider using the DisconnectCustomKeyStore operation to disconnect the custom key store from its backing key store. While the key store is disconnected, you cannot create or use the KMS keys in the key store. But, you do not need to delete KMS keys and you can reconnect a disconnected custom key store at any time.

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 AWS account.

Required permissions: kms:DeleteCustomKeyStore (IAM policy)

Errors

For information about the errors that are common to all actions, see Common Errors.

CustomKeyStoreHasCMKsException

The request was rejected because the custom key store contains KMS keys. After verifying that you do not need to use the KMS keys, use the ScheduleKeyDeletion operation to delete the KMS keys. After they are deleted, you can delete the custom key store.

HTTP Status Code: 400

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 AWS CloudHSM key store that is not connected. This operation is valid only when the AWS CloudHSM key store ConnectionState is CONNECTED.

HTTP Status Code: 400

CustomKeyStoreNotFoundException

The request was rejected because AWS KMS cannot find a custom key store with the specified key store name or ID.

HTTP Status Code: 400

KMSInternalException

The request was rejected because an internal exception occurred. The request can be retried.
