# put-bucket-encryption

Available in Classic and VPC

Register or override the default server-side encryption (SSE) settings for an Ncloud Storage bucket. If default encryption is enabled for the bucket, these settings are automatically applied during upload without the need to specify a separate encryption header.

              Note

              

For a Sub Account user to execute this command, they must have the Change/PutEncryptionConfiguration action permission.

```
aws s3api put-bucket-encryption \
