Overview

A key cannot be recovered after being deleted, and all data encrypted with it cannot be decrypted. To prevent accidental deletion, KMS adopts a scheduled deletion mechanism, i.e., a mandatory waiting period of 7-30 days is imposed on a deletion operation. Within the waiting period, you can cancel the deletion.

You can log in to the KMS console or call KMS TCCLI to create and cancel a scheduled deletion task. This guide describes how to delete a key in the console.

Directions

1. Log in to the KMS Console.
2. Select the key to be deleted, and click Schedule Deletion on the right. If the key is enabled, please disable it first.
   
3. Enter the days of waiting period, click OK. The key will be deleted as scheduled.
   

   Note：

   The waiting period can be set to 7-30 days. After being deleted, a key cannot be recovered, and all data encrypted with it cannot be decrypted.
   To prevent accidental deletion, the KMS automatic alarm will be triggered:

   • Before a key is deleted, any attempt to call the key will trigger the alarm.
   • The alarm will be triggered every day in the last 3 days before a key is deleted.

4. If you need to cancel the scheduled deletion task, click Cancel Deletion. After the key is reset to "Disabled" status, you can enable/modify/delete it or perform other operations.
