When Should I Use a CMK Created with Imported Key Materials?

  • If you do not want to use KMS-generated key materials, you can import your own key materials to create a CMK. Such a CMK allows deletion of only the key materials when you do not need it. In addition, when you find that the key materials are mis-deleted, you can import the same materials to the CMK.
  • You can also import local key materials to KMS when you want to use the same keys on cloud and on-premises. This practice has proved useful when user migrate local encrypted data to the cloud.
