# AWS::MediaPackage::PackagingConfiguration HlsEncryption
<a name="aws-properties-mediapackage-packagingconfiguration-hlsencryption"></a>

Holds encryption information so that access to the content can be controlled by a DRM solution.

## Syntax
<a name="aws-properties-mediapackage-packagingconfiguration-hlsencryption-syntax"></a>

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

### JSON
<a name="aws-properties-mediapackage-packagingconfiguration-hlsencryption-syntax.json"></a>

```
{
  "[ConstantInitializationVector](#cfn-mediapackage-packagingconfiguration-hlsencryption-constantinitializationvector)" : String,
  "[EncryptionMethod](#cfn-mediapackage-packagingconfiguration-hlsencryption-encryptionmethod)" : String,
  "[SpekeKeyProvider](#cfn-mediapackage-packagingconfiguration-hlsencryption-spekekeyprovider)" : SpekeKeyProvider
}
```

### YAML
<a name="aws-properties-mediapackage-packagingconfiguration-hlsencryption-syntax.yaml"></a>

```
  [ConstantInitializationVector](#cfn-mediapackage-packagingconfiguration-hlsencryption-constantinitializationvector): String
  [EncryptionMethod](#cfn-mediapackage-packagingconfiguration-hlsencryption-encryptionmethod): String
  [SpekeKeyProvider](#cfn-mediapackage-packagingconfiguration-hlsencryption-spekekeyprovider): 
    SpekeKeyProvider
```

## Properties
<a name="aws-properties-mediapackage-packagingconfiguration-hlsencryption-properties"></a>

`ConstantInitializationVector`  <a name="cfn-mediapackage-packagingconfiguration-hlsencryption-constantinitializationvector"></a>
A 128-bit, 16-byte hex value represented by a 32-character string, used with the key for encrypting blocks. If you don't specify a constant initialization vector (IV), AWS Elemental MediaPackage periodically rotates the IV.
