ServerSideEncryptionByDefault - Amazon Simple Storage Service
AWS services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with AWS services in China.

ServerSideEncryptionByDefault

Describes 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. For more information, see PUT Bucket encryption in the Amazon Simple Storage Service API Reference.

KMSMasterKeyID

AWS Key Management Service (KMS) customer master key ID to use for the default encryption. This parameter is allowed if and only if SSEAlgorithm is set to aws:kms.

You can specify the key ID or the Amazon Resource Name (ARN) of the CMK. However, if you are using encryption with cross-account operations, you must use a fully qualified CMK ARN. For more information, see Using encryption for cross-account operations.

For example:

  • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

  • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

Important

Amazon S3 only supports symmetric CMKs and not asymmetric CMKs. For more information, see Using Symmetric and Asymmetric Keys in the AWS Key Management Service Developer Guide.
