RotateKeyOnDemand

Immediately initiates rotation of the key material of the specified symmetric encryption KMS key.

You can perform on-demand rotation of the key material in customer managed KMS keys, regardless of whether or not automatic key rotation is enabled. On-demand rotations do not change existing automatic rotation schedules. For example, consider a KMS key that has automatic key rotation enabled with a rotation period of 730 days. If the key is scheduled to automatically rotate on April 14, 2024, and you perform an on-demand rotation on April 10, 2024, the key will automatically rotate, as scheduled, on April 14, 2024 and every 730 days thereafter.

Note

You can perform on-demand key rotation a maximum of 10 times per KMS key. You can use the AWS KMS console to view the number of remaining on-demand rotations available for a KMS key.

You can use GetKeyRotationStatus to identify any in progress on-demand rotations. You can use ListKeyRotations to identify the date that completed on-demand rotations were performed. You can monitor rotation of the key material for your KMS keys in AWS CloudTrail and Amazon CloudWatch.

On-demand key rotation is supported only on symmetric encryption KMS keys. You cannot perform on-demand rotation of asymmetric KMS keys, HMAC KMS keys, KMS keys with imported key material, or KMS keys in a custom key store. To perform on-demand rotation of a set of related multi-Region keys, invoke the on-demand rotation on the primary key.

You cannot initiate on-demand rotation of AWS managed KMS keys. AWS KMS always rotates the key material of AWS managed keys every year. Rotation of AWS owned KMS keys is managed by the AWS service that owns the key.

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

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

Required permissions: kms:RotateKeyOnDemand (key policy)

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

Request Syntax

   "KeyId": "string"
}

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

KeyId

Identifies a symmetric encryption KMS key. You cannot perform on-demand rotation of asymmetric KMS keys, HMAC KMS keys, KMS keys with imported key material, or KMS keys in a custom key store. To perform on-demand rotation of a set of related multi-Region keys, invoke the on-demand rotation on the primary key.

Specify the key ID or key ARN of the KMS key.

For example:

Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: Yes

Response Syntax

   "KeyId": "string"
}

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

KeyId

Identifies the symmetric encryption KMS key that you initiated on-demand rotation on.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Errors

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

ConflictException

The request was rejected because an automatic rotation of this key is currently in progress or scheduled to begin within the next 20 minutes.

HTTP Status Code: 400

DependencyTimeoutException

The system timed out while trying to fulfill the request. You can retry the request.

HTTP Status Code: 500

DisabledException

The request was rejected because the specified KMS key is not enabled.

HTTP Status Code: 400

InvalidArnException

The request was rejected because a specified ARN, or an ARN in a key policy, is not valid.

HTTP Status Code: 400

KMSInternalException

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

HTTP Status Code: 500

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 AWS KMS operation, see Key states of AWS KMS keys in the AWS 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.

HTTP Status Code: 400

LimitExceededException

The request was rejected because a length constraint or quota was exceeded. For more information, see Quotas in the AWS Key Management Service Developer Guide.

HTTP Status Code: 400

NotFoundException

The request was rejected because the specified entity or resource could not be found.

HTTP Status Code: 400

UnsupportedOperationException

The request was rejected because a specified parameter is not supported or a specified resource is not valid for this operation.

HTTP Status Code: 400
