getKeyRotationStatus method

Future<GetKeyRotationStatusResponse> getKeyRotationStatus({
  1. required String keyId,
})

Provides detailed information about the rotation status for a KMS key, including whether automatic rotation of the key material is enabled for the specified KMS key, the rotation period, and the next scheduled rotation date.

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 can enable (EnableKeyRotation) and disable automatic rotation (DisableKeyRotation) of the key material in customer managed KMS keys. Key material rotation of Amazon Web Services managed KMS keys is not configurable. KMS always rotates the key material in Amazon Web Services managed KMS keys every year. The key rotation status for Amazon Web Services managed KMS keys is always true.

You can perform on-demand (RotateKeyOnDemand) rotation of the key material in customer managed KMS keys, regardless of whether or not automatic key rotation is enabled. You can use GetKeyRotationStatus to identify the date and time that an in progress on-demand rotation was initiated. You can use ListKeyRotations to view the details of completed rotations. 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.

  • Disabled: The key rotation status does not change when you disable a KMS key. However, while the KMS key is disabled, KMS does not rotate the key material. When you re-enable the KMS key, rotation resumes. If the key material in the re-enabled KMS key hasn't been rotated in one year, KMS rotates it immediately, and every year thereafter. If it's been less than a year since the key material in the re-enabled KMS key was rotated, the KMS key resumes its prior rotation schedule.
  • Pending deletion: While a KMS key is pending deletion, its key rotation status is false and KMS does not rotate the key material. If you cancel the deletion, the original key rotation status returns to true.
Cross-account use: Yes. To perform this operation on a KMS key in a different Amazon Web Services account, specify the key ARN in the value of the KeyId parameter.

Required permissions: kms:GetKeyRotationStatus (key policy)

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

May throw DependencyTimeoutException. May throw InvalidArnException. May throw KMSInternalException. May throw KMSInvalidStateException. May throw NotFoundException. May throw UnsupportedOperationException.

Parameter keyId : Gets the rotation status for the specified KMS key.

Specify the key ID or key ARN of the KMS key. To specify a KMS key in a different Amazon Web Services account, you must use the key ARN.

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.
