# AWS::S3::Bucket MetadataTableEncryptionConfiguration
<a name="aws-properties-s3-bucket-metadatatableencryptionconfiguration"></a>

 The encryption settings for an S3 Metadata journal table or inventory table configuration. 

## Syntax
<a name="aws-properties-s3-bucket-metadatatableencryptionconfiguration-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-s3-bucket-metadatatableencryptionconfiguration-syntax.json"></a>

```
{
  "[KmsKeyArn](#cfn-s3-bucket-metadatatableencryptionconfiguration-kmskeyarn)" : String,
  "[SseAlgorithm](#cfn-s3-bucket-metadatatableencryptionconfiguration-ssealgorithm)" : String
}
```

### YAML
<a name="aws-properties-s3-bucket-metadatatableencryptionconfiguration-syntax.yaml"></a>

```
  [KmsKeyArn](#cfn-s3-bucket-metadatatableencryptionconfiguration-kmskeyarn): String
  [SseAlgorithm](#cfn-s3-bucket-metadatatableencryptionconfiguration-ssealgorithm): String
```

## Properties
<a name="aws-properties-s3-bucket-metadatatableencryptionconfiguration-properties"></a>

`KmsKeyArn`  <a name="cfn-s3-bucket-metadatatableencryptionconfiguration-kmskeyarn"></a>
 If server-side encryption with AWS Key Management Service (AWS KMS) keys (SSE-KMS) is specified, you must also specify the KMS key Amazon Resource Name (ARN). You must specify a customer-managed KMS key that's located in the same Region as the general purpose bucket that corresponds to the metadata table configuration.   
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`SseAlgorithm`  <a name="cfn-s3-bucket-metadatatableencryptionconfiguration-ssealgorithm"></a>
 The encryption type specified for a metadata table. To specify server-side encryption with AWS Key Management Service (AWS KMS) keys (SSE-KMS), use the `aws:kms` value. To specify server-side encryption with Amazon S3 managed keys (SSE-S3), use the `AES256` value.   
*Required*: Yes  
*Type*: String  
*Allowed values*: `aws:kms | AES256`
