// This operation is not supported by directory buckets.
//
// Returns the default encryption configuration for an Amazon S3 bucket. By
// default, all buckets have a default encryption configuration that uses
// server-side encryption with Amazon S3 managed keys (SSE-S3). For information
// about the bucket default encryption feature, see [Amazon S3 Bucket Default Encryption]in the Amazon S3 User Guide.
//
// To use this operation, you must have permission to perform the
// s3:GetEncryptionConfiguration action. 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 Subresource Operations]and [Managing Access Permissions to Your Amazon S3 Resources].
