Configuring Bucket Server-Side Encryption

You can configure server-side encryption for an OBS bucket. Once configured, any objects you upload to the bucket will be encrypted with the specified KMS key by default.

You can enable server-side encryption when creating a bucket (see Creating a Bucket). You can also enable or disable server-side encryption for an existing bucket.

OBS only encrypts the objects uploaded after server-side encryption is enabled for the bucket, and does not encrypt those uploaded before. After server-side encryption is disabled, encryption status of existing objects in the bucket remains unchanged, and you can still encrypt objects when you upload them.

Enabling Server-Side Encryption for a Bucket

In the navigation pane of OBS Console, choose Object Storage.
In the bucket list, click the bucket you want to operate to go to the Objects page.
In the navigation pane, choose Overview.
In the Basic Configurations area, click Server-Side Encryption. The Server-Side Encryption dialog box is displayed.
Select Enable.

Key obs/default is selected by default for KMS 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.
