 * <p>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 <a href="https://docs.aws.amazon.com/AmazonS3/latest/dev/bucket-encryption.html">Amazon S3 Bucket
 *             Default Encryption</a> in the <i>Amazon S3 User Guide</i>.</p>
 *          <p>To use this operation, you must have permission to perform the
 *             <code>s3:GetEncryptionConfiguration</code> action. The bucket owner has this permission
 *          by default. The bucket owner can grant this permission to others. For more information
 *          about permissions, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-with-s3-actions.html#using-with-s3-actions-related-to-bucket-subresources">Permissions Related to Bucket Subresource Operations</a> and <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-access-control.html">Managing
 *             Access Permissions to Your Amazon S3 Resources</a>.</p>

 * };
 * const command = new GetBucketEncryptionCommand(input);
 * const response = await client.send(command);
 * // { // GetBucketEncryptionOutput
 * //   ServerSideEncryptionConfiguration: { // ServerSideEncryptionConfiguration
 * //     Rules: [ // ServerSideEncryptionRules // required
