Enable Key Rotation
kms_enable_key_rotation | R Documentation |
Enables automatic rotation of the key material of the specified symmetric encryption KMS key¶
Description¶
Enables automatic rotation of the key material of the specified symmetric encryption KMS key.
By default, 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 use the
optional RotationPeriodInDays
parameter to specify a custom rotation
period when you enable key rotation, or you can use
RotationPeriodInDays
to modify the rotation period of a key that you
previously enabled automatic key rotation on.
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 disable_key_rotation
operation. You can use the get_key_rotation_status
operation to
identify any in progress rotations. You can use the list_key_rotations
operation to view the details of completed rotations.
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 of 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 is managed by the Amazon Web Services service that owns the key.
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)

You can perform on-demand (
rotate_key_on_demand
) rotation of the key material in customer managed KMS keys, regardless of whether or not automatic key rotation is enabled.
Eventual consistency: The KMS API follows an eventual consistency model. For more information, see KMS eventual consistency.
Usage¶
Arguments¶
KeyId
[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
list_keys
ordescribe_key
.RotationPeriodInDays
Use this parameter to specify a custom period of time between each rotation date. If no value is specified, the default value is 365 days.
The rotation period defines the number of days after you enable automatic key rotation that KMS will rotate your key material, and the number of days between each automatic rotation thereafter.
You can use the
kms:RotationPeriodInDays
condition key to further constrain the values that principals can specify in theRotationPeriodInDays
parameter.
Value¶
An empty list.
