Which Cloud Services Can Use KMS for Encryption?¶
Object Storage Service (OBS), Elastic Volume Service (EVS), and Image Management Service (IMS) can use KMS for encryption.
Service Name | Description |
|---|---|
Object Storage Service (OBS) | You can upload objects to and download them from Object Storage Service (OBS) in common mode or server-side encryption mode. When you upload objects in encryption mode, data is encrypted at the server side and then securely stored on OBS in ciphertext. When you download encrypted objects, the data in ciphertext is decrypted at the server side and then provided to you in plaintext. OBS supports the server-side encryption with KMS-managed keys (SSE-KMS) mode. In SSE-KMS mode, OBS uses the keys provided by KMS for server-side encryption. For details about how to upload objects to OBS in SSE-KMS mode, see the Object Storage Service User Guide. |
Elastic Volume Service (EVS) | If you enable the encryption function when creating an EVS disk, the disk will be encrypted with the DEK generated by using your CMK. Data stored in the EVS disk will be automatically encrypted. For details about how to use the encryption function of EVS, see Elastic Volume Service User Guide. |
Image Management Service (IMS) | When creating a private image using an external image file, you can enable the private image encryption function and select a CMK provided by KMS to encrypt the image. For details about how to use the private image encryption function of Image Management Service (IMS), see Image Management Service User Guide. |
