EnableKeyRotation
Enables automatic rotation of the key material of the specified symmetric encryption KMS key.
When you enable automatic rotation of a customer managed KMS key, Amazon 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 Amazon 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 managed KMS keys. Amazon KMS always rotates the key material of Amazon managed keys every year. Rotation of Amazon owned KMS keys varies.
Note
In May 2022, Amazon KMS changed the rotation schedule for Amazon managed keys from every three years (approximately 1,095 days) to every year (approximately 365 days).
New Amazon managed keys are automatically rotated one year after they are created, and approximately every year thereafter.
Existing Amazon 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 Amazon KMS keys in the Amazon 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)

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 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.
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 Elements
If the action is successful, the service sends back an HTTP 200 response with an empty HTTP body.
Errors
For information about the errors that are common to all actions, see Common Errors.
- 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 Amazon KMS operation, see Key states of Amazon KMS keys in the Amazon 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
-
- 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
