This operation configures default encryption and Amazon S3 Bucket Keys for an existing
bucket.
Directory buckets - For directory buckets, you must make requests for this
API operation to the Regional endpoint. These endpoints support path-style requests
in the format https://s3express-control.region-code.amazonaws.com/bucket-name. Virtual-hosted-style requests aren't supported. For more information about endpoints
in Availability Zones, see Regional
and Zonal endpoints for directory buckets in Availability Zones in the Amazon
S3 User Guide. For more information about endpoints in Local Zones, see Available
Local Zone for directory buckets in the Amazon S3 User Guide.
By default, all buckets have a default encryption configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3).
General purpose buckets
You can optionally configure default encryption for a bucket by using server-side encryption with Key Management Service (KMS) keys (SSE-KMS) or dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS). If you specify default encryption by using SSE-KMS, you can also configure Amazon S3 Bucket Keys. For information about the bucket default encryption feature, see Amazon S3 Bucket Default Encryption in the Amazon S3 User Guide.
If you use PutBucketEncryption to set your default bucket encryption to SSE-KMS, you should verify that your KMS key ID is correct. Amazon S3 doesn't validate the KMS key ID provided in PutBucketEncryption requests.
Directory buckets - You can optionally configure default encryption for a bucket by using server-side encryption with Key Management Service (KMS) keys (SSE-KMS).
We recommend that the bucket's default encryption uses the desired encryption configuration
and you don't override the bucket default encryption in your CreateSession
requests or PUT object requests. Then, new objects are automatically encrypted
with the desired encryption settings. For more information about the encryption overriding
behaviors in directory buckets, see Specifying
server-side encryption with KMS for new object uploads.
Your SSE-KMS configuration can only support 1 customer
managed key per directory bucket for the lifetime of the bucket. The Amazon
Web Services managed key (aws/s3) isn't supported.
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.
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.
For directory buckets, if you use PutBucketEncryption to set your default bucket encryption to SSE-KMS, Amazon S3 validates the KMS key ID provided in PutBucketEncryption requests.
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.
Also, this action requires Amazon Web Services Signature Version 4. For more information, see Authenticating Requests (Amazon Web Services Signature Version 4).
General purpose bucket permissions - The s3:PutEncryptionConfiguration
permission is required in a policy. The bucket owner has this permission by default.
The bucket owner can grant this permission to others. For more information about permissions,
see Permissions
Related to Bucket Operations and Managing
Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.
Directory bucket permissions - To grant access to this API operation, you
must have the s3express:PutEncryptionConfiguration permission in an IAM identity-based
policy instead of a bucket policy. Cross-account access to this API operation isn't
supported. This operation can only be performed by the Amazon Web Services account
that owns the resource. For more information about directory bucket policies and permissions,
see Amazon
Web Services Identity and Access Management (IAM) for S3 Express One Zone in the
Amazon S3 User Guide.
To set a directory bucket default encryption with SSE-KMS, you must also have the
kms:GenerateDataKey and the kms:Decrypt permissions in IAM identity-based
policies and KMS key policies for the target KMS key.
Directory buckets - The HTTP Host header syntax is s3express-control.region-code.amazonaws.com.
