bucketKeyEnabled

Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using Amazon Web Services KMS (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

Specifying this header with an object action doesn’t affect bucket-level settings for S3 Bucket Key.

This functionality is not supported by directory buckets.
