get_key_rotation_status

KMS.Client.get_key_rotation_status(**kwargs)

Gets a Boolean value that indicates whether automatic rotation of the key material is enabled for the specified KMS key.

When you enable automatic rotation for customer managed KMS keys, 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.

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 .

Note

In May 2022, KMS changed the rotation schedule for Amazon Web Services managed keys from every three years to every year. For details, see EnableKeyRotation.

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.

Request Syntax

response = client.get_key_rotation_status(
    KeyId='string'
)

Parameters

KeyId (string) --

[REQUIRED]

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.

Return type

dict

Returns

Response Syntax

{
    'KeyRotationEnabled': True|False
}

Response Structure

• (dict) --
  • KeyRotationEnabled (boolean) --

    A Boolean value that specifies whether key rotation is enabled.

Exceptions

• KMS.Client.exceptions.NotFoundException
• KMS.Client.exceptions.InvalidArnException

Examples

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

response = client.get_key_rotation_status(
    # The identifier of the KMS key whose key material rotation status you want to retrieve. You can use the key ID or the Amazon Resource Name (ARN) of the KMS key.
    KeyId='1234abcd-12ab-34cd-56ef-1234567890ab',
)

print(response)

Expected Output:

{
    # A boolean that indicates the key material rotation status. Returns true when automatic annual rotation of the key material is enabled, or false when it is not.
    'KeyRotationEnabled': True,
    'ResponseMetadata': {
        '...': '...',
    },
}
