AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Specifies the default server-side encryption configuration.

  • 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 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 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.

Properties

NameTypeDescription
Public Property BlockedEncryptionTypes Amazon.S3.Model.BlockedEncryptionTypes

Gets and sets the property BlockedEncryptionTypes.

A bucket-level setting for Amazon S3 general purpose buckets used to prevent the upload of new objects encrypted with the specified server-side encryption type. For example, blocking an encryption type will block PutObject, CopyObject, PostObject, multipart upload, and replication requests to the bucket for objects with the specified encryption type. However, you can continue to read and list any pre-existing objects already encrypted with the specified encryption type. For more information, see Blocking an encryption type for a general purpose bucket.

Currently, this parameter only supports blocking or unblocking Server Side Encryption with Customer Provided Keys (SSE-C). For more information about SSE-C, see Using server-side encryption with customer-provided keys (SSE-C).

Public Property BucketKeyEnabled System.Boolean

Specifies whether Amazon S3 should use bucket key with server-side encryption using KMS (SSE-KMS) for new objects in the bucket. Existing objects are not affected. Setting the BucketKeyEnabled element to true causes Amazon S3 to use bucket key.

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 GET and PUT operations 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 KMS every time a copy request is made for a KMS-encrypted object.

Public Property ServerSideEncryptionByDefault Amazon.S3.Model.ServerSideEncryptionByDefault

Describes the default server-side encryption to apply to new objects in the bucket. If Put Object request does not specify any server-side encryption, this default encryption will be applied.
