sseAlgorithm

The server-side encryption algorithm used when storing objects in Amazon S3.

**Directory buckets ** - For directory buckets, there are only two supported options for server-side encryption: server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) and server-side encryption with KMS keys (SSE-KMS) (KMS). For more information, see Protecting data with server-side encryption in the Amazon S3 User Guide. For the Copy operation in Batch Operations, see S3CopyObjectOperation.
