# AWS::DynamoDB::Table SSESpecification
<a name="aws-properties-dynamodb-table-ssespecification"></a>

Represents the settings used to enable server-side encryption.

## Syntax
<a name="aws-properties-dynamodb-table-ssespecification-syntax"></a>

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

### JSON
<a name="aws-properties-dynamodb-table-ssespecification-syntax.json"></a>

```
{
  "[KMSMasterKeyId](#cfn-dynamodb-table-ssespecification-kmsmasterkeyid)" : String,
  "[SSEEnabled](#cfn-dynamodb-table-ssespecification-sseenabled)" : Boolean,
  "[SSEType](#cfn-dynamodb-table-ssespecification-ssetype)" : String
}
```

### YAML
<a name="aws-properties-dynamodb-table-ssespecification-syntax.yaml"></a>

```
  [KMSMasterKeyId](#cfn-dynamodb-table-ssespecification-kmsmasterkeyid): String
  [SSEEnabled](#cfn-dynamodb-table-ssespecification-sseenabled): Boolean
  [SSEType](#cfn-dynamodb-table-ssespecification-ssetype): String
```

## Properties
<a name="aws-properties-dynamodb-table-ssespecification-properties"></a>

`KMSMasterKeyId`  <a name="cfn-dynamodb-table-ssespecification-kmsmasterkeyid"></a>
The AWS KMS key that should be used for the AWS KMS encryption. To specify a key, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. Note that you should only provide this parameter if the key is different from the default DynamoDB key `alias/aws/dynamodb`.
