OBS allows you to encrypt objects using server-side encryption so that the objects can be securely stored in OBS.
In the region where OBS is deployed, the KMS Administrator permission has been added to the user group. For details about how to add permissions, see the IAM User Guide.
If the default encryption has been enabled for the bucket, uploaded objects are automatically encrypted.
After KMS encryption is selected, obs/default is selected by default as the key for the encryption. You can also click Create KMS Key to switch to the KMS management console and create a customer master key. Then go back to OBS Console and select the key from the drop-down list.
After the object is uploaded successfully, you can view its encryption status in the object list.
