Deleting One or More CMKs¶
Before deleting the CMK, confirm that it is not in use and will not be used.
Check the CMK permission to determine its possible usage scope. For details, see Querying a Grant.
Check audit logs to determine the actual usage.
Prerequisites¶
The CMK you want to schedule deletion for is in Enabled or Disabled status.
Constraints¶
A key will not be deleted until its scheduled deletion period expires. You can set the period to a value within the range 7 to 1096 days.
Before the specified deletion date, you can cancel the deletion if you want to use the CMK. Once the scheduled deletion has taken effect, the CMK will be deleted permanently and you will not be able to decrypt data encrypted by the CMK. Exercise caution when performing this operation.
Default Master Keys created by KMS cannot be scheduled for deletion.
A CMK in pending deletion status does not incur charges. If you cancel deletion, the charging resumes from the time when the CMK was scheduled to be deleted.
