Bucket Default Encryption

OBS enables you to configure default encryption for a bucket. After the configuration, objects uploaded to the bucket are automatically encrypted using the specified KMS key, improving data storage security.

You can enable the default encryption when creating a bucket. For details, see Creating a Bucket. You can also enable or disable the default encryption after a bucket is created.

OBS encrypts only the objects uploaded after the default encryption function is enabled, and does not encrypt those uploaded before. After default encryption is disabled, the encryption status of existing objects keeps unchanged, and you can still manually encrypt objects upon upload.
