OBS allows users to encrypt objects using server-side encryption so that the objects can be securely stored on OBS.
The KMS Administrator permission has been added in the region of OBS using Identity and Access Management (IAM). For details about how to add the permission, see "How Do I Manage User Groups and Grant Permissions to Them?" in the Identity and Access Management User Guide.
If Enable HTTPS and Enable KMS encryption are selected, KMS encryption will be implemented for all objects uploaded to OBS. After objects are uploaded, click on the right of the object list. In the Properties dialog box that is displayed in Figure 2, view the object encryption status. KMS encryption indicates that server-side encryption has been implemented for the object. No indicates that server-side encryption has not been implemented for the object. The object encryption status cannot be changed.
HTTPS must be enabled when you enable KMS encryption to upload objects. Therefore, if you deselect Enable HTTPS, Enable KMS encryption is deselected automatically.
