KMS / Client / enable_key_rotation

enable_key_rotation#

KMS.Client.enable_key_rotation(**kwargs)#

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, 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.

Note

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)

Request Syntax

response = client.enable_key_rotation(
    KeyId='string'
)
Parameters:

KeyId (string) –

[REQUIRED]

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.

Returns:

None

Exceptions

  • KMS.Client.exceptions.NotFoundException

  • KMS.Client.exceptions.DisabledException

  • KMS.Client.exceptions.InvalidArnException

  • KMS.Client.exceptions.DependencyTimeoutException

  • KMS.Client.exceptions.KMSInternalException

  • KMS.Client.exceptions.KMSInvalidStateException

  • KMS.Client.exceptions.UnsupportedOperationException

Examples

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

response = client.enable_key_rotation(
    # 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.
    KeyId='1234abcd-12ab-34cd-56ef-1234567890ab',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
