EnableKeyRotation

Enables automatic rotation of the key material of the specified symmetric encryption KMS key.

When you enable automatic rotation of acustomer managed KMS key, AWS 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 AWS 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 or disable automatic rotation of asymmetric KMS keys, HMAC KMS keys, KMS keys with imported key material, or KMS keys in a custom key store. The key rotation status of these KMS keys is always false. 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 AWS managed KMS keys. AWS KMS always rotates the key material of AWS managed keys every year. Rotation of AWS owned KMS keys varies.

Note

In May 2022, AWS KMS changed the rotation schedule for AWS managed keys from every three years (approximately 1,095 days) to every year (approximately 365 days).

New AWS managed keys are automatically rotated one year after they are created, and approximately every year thereafter.

Existing AWS 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 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.

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 or disable automatic rotation of asymmetric KMS keys, HMAC KMS keys, KMS keys with imported key material, or KMS keys in a custom key store. The key rotation status of these KMS keys is always false. 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
