# `ScheduleKeyDeletion`与 AWS SDK 或 CLI 配合使用
以下代码示例演示如何使用 `ScheduleKeyDeletion`。
操作示例是大型程序的代码摘录，必须在上下文中运行。在以下代码示例中，您可以查看此操作的上下文：
+ [了解基本功能](example_kms_Scenario_Basics_section.md)
------
#### [ CLI ]
**AWS CLI**
**计划删除客户托管的 KMS 密钥。**
以下 `schedule-key-deletion` 示例计划在 15 天后删除指定的客户托管 KMS 密钥。
`--key-id` 参数识别 KMS 密钥。此示例使用密钥 ARN 值，但您可以使用 KMS 密钥的密钥 ID 或 ARN。`--pending-window-in-days` 参数指定 7-30 天的等待期限。默认的等待期限为 30 天。此示例指定的值为 15，表示在命令完成 15 天后永久删除 KMS 密钥。 AWS
```
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
```
响应包括密钥 ARN、密钥状态、等待期（`PendingWindowInDays`）和删除日期（以 Unix 时间表示）。要以当地时间查看删除日期，请使用 AWS KMS 控制台。无法在加密操作中使用密钥状态为 `PendingDeletion` 的 KMS 密钥。
```
{
"KeyId": "arn:aws:kms:us-west-2:123456789012:key/1234abcd-12ab-34cd-56ef-1234567890ab",
"DeletionDate": "2022-06-18T23:43:51.272000+00:00",
"KeyState": "PendingDeletion",
"PendingWindowInDays": 15
}
```
