// Returns the default encryption configuration for an Amazon S3 bucket. If the
// bucket does not have a default encryption configuration, GetBucketEncryption
// returns ServerSideEncryptionConfigurationNotFoundError. For information about
// the Amazon S3 default encryption feature, see Amazon S3 Default Bucket
// Encryption
// (https://docs.aws.amazon.com/AmazonS3/latest/dev/bucket-encryption.html). 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
