Enables automatic rotation of the key material of the specified symmetric encryption KMS key.

When you enable automatic rotation of acustomer managed KMS key, KMS rotates the key material of the KMS key one year (approximately 365 days) from the enable date and every year thereafter. You can monitor rotation of the key material for your KMS keys in CloudTrail and Amazon CloudWatch. To disable rotation of the key material in a customer managed KMS key, use the DisableKeyRotation operation.

Automatic key rotation is supported only on symmetric encryption KMS keys. You cannot enable automatic rotation of asymmetric KMS keys, HMAC KMS keys, KMS keys with imported key material, or KMS keys in a custom key store. To enable or disable automatic rotation of a set of related multi-Region keys, set the property on the primary key.

You cannot enable or disable automatic rotation Amazon Web Services managed KMS keys. KMS always rotates the key material of Amazon Web Services managed keys every year. Rotation of Amazon Web Services owned KMS keys varies.

In May 2022, KMS changed the rotation schedule for Amazon Web Services managed keys from every three years (approximately 1,095 days) to every year (approximately 365 days).

New Amazon Web Services managed keys are automatically rotated one year after they are created, and approximately every year thereafter.

Existing Amazon Web Services managed keys are automatically rotated one year after their most recent rotation, and every year thereafter.

The KMS key that you use for this operation must be in a compatible key state. For details, see Key states of KMS keys in the Key Management Service Developer Guide.

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

Required permissions: kms:EnableKeyRotation (key policy)

Note:

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

Namespace: Amazon.KeyManagementService

Syntax

C#
public virtual EnableKeyRotationResponse EnableKeyRotation(
         EnableKeyRotationRequest request
)
Parameters
request
Type: Amazon.KeyManagementService.Model.EnableKeyRotationRequest

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

Return Value
The response from the EnableKeyRotation service method, as returned by KeyManagementService.

Exceptions

ExceptionCondition
DependencyTimeoutException The system timed out while trying to fulfill the request. You can retry the request.
DisabledException The request was rejected because the specified KMS key is not enabled.
InvalidArnException The request was rejected because a specified ARN, or an ARN in a key policy, is not valid.
KMSInternalException The request was rejected because an internal exception occurred. The request can be retried.
KMSInvalidStateException The request was rejected because the state of the specified resource is not valid for this request. This exceptions means one of the following: The key state of the KMS key is not compatible with the operation. To find the key state, use the DescribeKey operation. For more information about which key states are compatible with each KMS operation, see Key states of KMS keys in the Key Management Service Developer Guide. For cryptographic operations on KMS keys in custom key stores, this exception represents a general failure with many possible causes. To identify the cause, see the error message that accompanies the exception.
NotFoundException The request was rejected because the specified entity or resource could not be found.
UnsupportedOperationException The request was rejected because a specified parameter is not supported or a specified resource is not valid for this operation.

Examples

The following example enables automatic annual rotation of the key material for the specified KMS key.

To enable automatic rotation of key material


var client = new AmazonKeyManagementServiceClient();
var response = client.EnableKeyRotation(new EnableKeyRotationRequest 
{
    KeyId = "1234abcd-12ab-34cd-56ef-1234567890ab" // The identifier of the KMS key whose key material will be rotated annually. You can use the key ID or the Amazon Resource Name (ARN) of the KMS key.
});
