@Generated(value="com.ibm.cos.v2:codegen") public final class ServerSideEncryptionByDefault extends Object implements SdkPojo, Serializable, ToCopyableBuilder<ServerSideEncryptionByDefault.Builder,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 PutBucketEncryption.
General purpose buckets - If you don't specify a customer managed key at configuration, Amazon S3
automatically creates an Amazon Web Services KMS key (aws/s3) in your Amazon Web Services account the
first time that you add an object encrypted with SSE-KMS to a bucket. By default, Amazon S3 uses this KMS key for
SSE-KMS.
Directory buckets - Your SSE-KMS configuration can only support 1 customer managed key per
directory bucket's lifetime. The Amazon Web Services
managed key (aws/s3) isn't supported.
Directory buckets - For directory buckets, there are only two supported options for server-side encryption: SSE-S3 and SSE-KMS.

Server-side encryption algorithm to use for the default encryption.
For directory buckets, there are only two supported values for server-side encryption: AES256 and
aws:kms.
If the service returns an enum value that is not available in the current SDK version, sseAlgorithm will
return ServerSideEncryption.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available
from sseAlgorithmAsString().

ServerSideEncryptionpublic final String kmsMasterKeyID()
Amazon Web Services Key Management Service (KMS) customer managed key ID to use for the default encryption.
General purpose buckets - This parameter is allowed if and only if SSEAlgorithm is set to
aws:kms or aws:kms:dsse.
Directory buckets - This parameter is allowed if and only if SSEAlgorithm is set to
aws:kms.
You can specify the key ID, key alias, or the Amazon Resource Name (ARN) of the KMS key.
Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab
Key Alias: alias/alias-name
If you are using encryption with cross-account or Amazon Web Services service operations, you must use a fully qualified KMS key ARN. For more information, see Using encryption for cross-account operations.
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. Also, if you use a key ID, you can run into a LogDestination undeliverable error when creating a VPC flow log.
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.
Amazon S3 only supports symmetric encryption KMS keys. For more information, see Asymmetric keys in Amazon Web Services KMS in the Amazon Web Services Key Management Service Developer Guide.
