UpdateObjectEncryptionRequest

Class

Container for the parameters to the UpdateObjectEncryption operation.

This operation is not supported for directory buckets or Amazon S3 on Outposts buckets.

Updates the server-side encryption type of an existing encrypted object in a general purpose bucket. You can use the UpdateObjectEncryption operation to change encrypted objects from server-side encryption with Amazon S3 managed keys (SSE-S3) to server-side encryption with Key Management Service (KMS) keys (SSE-KMS), or to apply S3 Bucket Keys. You can also use the UpdateObjectEncryption operation to change the customer-managed KMS key used to encrypt your data so that you can comply with custom key-rotation standards.

Using the UpdateObjectEncryption operation, you can atomically update the server-side encryption type of an existing object in a general purpose bucket without any data movement. The UpdateObjectEncryption operation uses envelope encryption to re-encrypt the data key used to encrypt and decrypt your object with your newly specified server-side encryption type. In other words, when you use the UpdateObjectEncryption operation, your data isn't copied, archived objects in the S3 Glacier Flexible Retrieval and S3 Glacier Deep Archive storage classes aren't restored, and objects in the S3 Intelligent-Tiering storage class aren't moved between tiers. Additionally, the UpdateObjectEncryption operation preserves all object metadata properties, including the storage class, creation date, last modified date, ETag, and checksum properties. For more information, see Updating server-side encryption for existing objects in the Amazon S3 User Guide.

By default, all UpdateObjectEncryption requests that specify a customer-managed KMS key are restricted to KMS keys that are owned by the bucket owner's Amazon Web Services account. If you're using Organizations, you can request the ability to use KMS keys owned by other member accounts within your organization by contacting Amazon Web Services Support.

Permissions

• To use the UpdateObjectEncryption operation, you must have the following permissions:

  • s3:PutObject

  • s3:UpdateObjectEncryption

  • kms:Encrypt

  • kms:Decrypt

  • kms:GenerateDataKey

  • kms:ReEncrypt*

• If you're using Organizations, to use this operation with customer-managed KMS keys from other Amazon Web Services accounts within your organization, you must have the organizations:DescribeAccount permission.

Errors

• You might receive an InvalidRequest error for several reasons. Depending on the reason for the error, you might receive one of the following messages:

  • The UpdateObjectEncryption operation doesn't supported unencrypted source objects. Only source objects encrypted with SSE-S3 or SSE-KMS are supported.

  • The UpdateObjectEncryption operation doesn't support source objects with the encryption type DSSE-KMS or SSE-C. Only source objects encrypted with SSE-S3 or SSE-KMS are supported.

  • The UpdateObjectEncryption operation doesn't support updating the encryption type to DSSE-KMS or SSE-C. Modify the request to specify SSE-KMS for the updated encryption type, and then try again.

  • Requests that modify an object encryption configuration require Amazon Web Services Signature Version 4. Modify the request to use Amazon Web Services Signature Version 4, and then try again.

  • Requests that modify an object encryption configuration require a valid new encryption type. Valid values are SSEKMS. Modify the request to specify SSE-KMS for the updated encryption type, and then try again.

  • Requests that modify an object's encryption type to SSE-KMS require an Amazon Web Services KMS key Amazon Resource Name (ARN). Modify the request to specify a KMS key ARN, and then try again.

  • Requests that modify an object's encryption type to SSE-KMS require a valid Amazon Web Services KMS key Amazon Resource Name (ARN). Confirm that you have a correctly formatted KMS key ARN in your request, and then try again.

  • The BucketKeyEnabled value isn't valid. Valid values are true or false. Modify the request to specify a valid value, and then try again.

• You might receive an AccessDenied error for several reasons. Depending on the reason for the error, you might receive one of the following messages:

  • The Amazon Web Services KMS key in the request must be owned by the same account as the bucket. Modify the request to specify a KMS key from the same account, and then try again.

  • The bucket owner's account was approved to make UpdateObjectEncryption requests that use any Amazon Web Services KMS key in their organization, but the bucket owner's account isn't part of an organization in Organizations. Make sure that the bucket owner's account and the specified KMS key belong to the same organization, and then try again.

  • The specified Amazon Web Services KMS key must be from the same organization in Organizations as the bucket. Specify a KMS key that belongs to the same organization as the bucket, and then try again.

  • The encryption type for the specified object can’t be updated because that object is protected by S3 Object Lock. If the object has a governance-mode retention period or a legal hold, you must first remove the Object Lock status on the object before you issue your UpdateObjectEncryption request. You can't use the UpdateObjectEncryption operation with objects that have an Object Lock compliance mode retention period applied to them.
