Specifies the default server-side encryption configuration.
Note
-
General purpose buckets - If you're specifying a customer managed KMS key, we recommend using a fully qualified KMS key ARN. If you use a KMS key alias instead, then AWS KMS resolves the key within the requester’s account. This behavior can result in data that's encrypted with a KMS key that belongs to the requester, and not the bucket owner.
-
Directory buckets - When you specify an AWS KMS customer managed key for encryption in your directory bucket, only use the key ID or key ARN. The key alias format of the KMS key isn't supported.
Contents
- ApplyServerSideEncryptionByDefault
-
Specifies the default server-side encryption to apply to new objects in the bucket. If a PUT Object request doesn't specify any server-side encryption, this default encryption will be applied.
Type: ServerSideEncryptionByDefault data type
Required: No
- BucketKeyEnabled
-
Specifies whether Amazon S3 should use an S3 Bucket Key with server-side encryption using KMS (SSE-KMS) for new objects in the bucket. Existing objects are not affected. Setting the
BucketKeyEnabledelement totruecauses Amazon S3 to use an S3 Bucket Key.Note
-
General purpose buckets - By default, S3 Bucket Key is not enabled. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide.
-
Directory buckets - S3 Bucket Keys are always enabled for
GETandPUToperations in a directory bucket and can’t be disabled. S3 Bucket Keys aren't supported, when you copy SSE-KMS encrypted objects from general purpose buckets to directory buckets, from directory buckets to general purpose buckets, or between directory buckets, through CopyObject, UploadPartCopy, the Copy operation in Batch Operations, or the import jobs. In this case, Amazon S3 makes a call to AWS KMS every time a copy request is made for a KMS-encrypted object.
