GetBucketEncryption - Amazon Simple Storage Service



This operation is not supported by directory buckets.

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.
