schedule-key-deletion

Description

Schedules the deletion of a KMS key. By default, KMS applies a waiting period of 30 days, but you can specify a waiting period of 7-30 days. When this operation is successful, the key state of the KMS key changes to PendingDeletion and the key can't be used in any cryptographic operations. It remains in this state for the duration of the waiting period. Before the waiting period ends, you can use CancelKeyDeletion to cancel the deletion of the KMS key. After the waiting period ends, KMS deletes the KMS key, its key material, and all KMS data associated with it, including all aliases that refer to it.

Warning

Deleting a KMS key is a destructive and potentially dangerous operation. When a KMS key is deleted, all data that was encrypted under the KMS key is unrecoverable. (The only exception is a multi-Region replica key.) To prevent the use of a KMS key without deleting it, use DisableKey .

If you schedule deletion of a KMS key from a custom key store , when the waiting period expires, ScheduleKeyDeletion deletes the KMS key from KMS. Then KMS makes a best effort to delete the key material from the associated CloudHSM cluster. However, you might need to manually delete the orphaned key material from the cluster and its backups.

You can schedule the deletion of a multi-Region primary key and its replica keys at any time. However, KMS will not delete a multi-Region primary key with existing replica keys. If you schedule the deletion of a primary key with replicas, its key state changes to PendingReplicaDeletion and it cannot be replicated or used in cryptographic operations. This status can continue indefinitely. When the last of its replicas keys is deleted (not just scheduled), the key state of the primary key changes to PendingDeletion and its waiting period (PendingWindowInDays ) begins. For details, see Deleting multi-Region keys in the Key Management Service Developer Guide .

For more information about scheduling a KMS key for deletion, see Deleting KMS keys in the Key Management Service Developer Guide .

The KMS key that you use for this operation must be in a compatible key state. For details, see Key state: Effect on your KMS key 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:ScheduleKeyDeletion (key policy)

Synopsis

  schedule-key-deletion
--key-id <value>
[--pending-window-in-days <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--key-id (string)

The unique identifier of the KMS key to delete.

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 .

--pending-window-in-days (integer)

The waiting period, specified in number of days. After the waiting period ends, KMS deletes the KMS key.

If the KMS key is a multi-Region primary key with replicas, the waiting period begins when the last of its replica keys is deleted. Otherwise, the waiting period begins immediately.

This value is optional. If you include a value, it must be between 7 and 30, inclusive. If you do not include a value, it defaults to 30.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To schedule the deletion of a customer managed CMK.

The following schedule-key-deletion example schedules the specified customer managed CMK to be deleted in 15 days.

  • The --key-id parameter identifies the CMK. This example uses a key ARN value, but you can use either the key ID or the ARN of the CMK.

  • The --pending-window-in-days parameter specifies the length of the waiting period. By default, the waiting period is 30 days. This example specifies a value of 15, which tells AWS to permanently delete the CMK 15 days after the command completes.

    aws kms schedule-key-deletion \
        --key-id arn:aws:kms:us-west-2:123456789012:key/1234abcd-12ab-34cd-56ef-1234567890ab \
        --pending-window-in-days 15
    

The response returns the key ARN and the deletion date in Unix time. To view the deletion date in local time, use the AWS KMS console.

{
    "KeyId": "arn:aws:kms:us-west-2:123456789012:key/1234abcd-12ab-34cd-56ef-1234567890ab",
    "DeletionDate": 1567382400.0
}

For more information, see Deleting Customer Master Keys in the AWS Key Management Service Developer Guide.

Output

KeyId -> (string)

The Amazon Resource Name (key ARN ) of the KMS key whose deletion is scheduled.

DeletionDate -> (timestamp)

The date and time after which KMS deletes the KMS key.

If the KMS key is a multi-Region primary key with replica keys, this field does not appear. The deletion date for the primary key isn't known until its last replica key is deleted.

KeyState -> (string)

The current status of the KMS key.

For more information about how key state affects the use of a KMS key, see Key state: Effect on your KMS key in the Key Management Service Developer Guide .

PendingWindowInDays -> (integer)

The waiting period before the KMS key is deleted.

If the KMS key is a multi-Region primary key with replicas, the waiting period begins when the last of its replica keys is deleted. Otherwise, the waiting period begins immediately.
