// 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). This operation also
// returns the [BucketKeyEnabled]and [BlockedEncryptionTypes] statuses.
//
//   - General purpose buckets - For information about the bucket default
//     encryption feature, see [Amazon S3 Bucket Default Encryption]in the Amazon S3 User Guide.
//
//   - Directory buckets - For directory buckets, there are only two supported
//     options for server-side encryption: SSE-S3 and SSE-KMS. For information about
//     the default encryption configuration in directory buckets, see [Setting default server-side encryption behavior for directory buckets].
//
// Permissions
//
//   - General purpose bucket permissions - The s3:GetEncryptionConfiguration
//     permission is required in a policy. 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 Operations]and [Managing Access Permissions to Your Amazon S3 Resources].
//
//   - Directory bucket permissions - To grant access to this API operation, you
//     must have the s3express:GetEncryptionConfiguration permission in an IAM
//     identity-based policy instead of a bucket policy. Cross-account access to this
//     API operation isn't supported. This operation can only be performed by the
//     Amazon Web Services account that owns the resource. For more information about
//     directory bucket policies and permissions, see [Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone]in the Amazon S3 User Guide.
//
// HTTP Host header syntax  Directory buckets - The HTTP Host header syntax is
// s3express-control.region-code.amazonaws.com .
//
// The following operations are related to GetBucketEncryption :
//
// [PutBucketEncryption]
//
// [DeleteBucketEncryption]
//
// You must URL encode any signed header values that contain spaces. For example,
// if your header value is my file.txt , containing two spaces after my , you must
// URL encode this value to my%20%20file.txt .
