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

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

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

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

### JSON

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

`ConstantInitializationVector`  <a name="cfn-mediapackage-originendpoint-hlsencryption-constantinitializationvector"></a>
A 128-bit, 16-byte hex value represented by a 32-character string, used with the key for encrypting blocks.  
*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)

`EncryptionMethod`  <a name="cfn-mediapackage-originendpoint-hlsencryption-encryptionmethod"></a>
HLS encryption type.  
*Required*: No  
*Type*: String  
*Allowed values*: `AES_128 | SAMPLE_AES`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`KeyRotationIntervalSeconds`  <a name="cfn-mediapackage-originendpoint-hlsencryption-keyrotationintervalseconds"></a>
Number of seconds before AWS Elemental MediaPackage rotates to a new key. By default, rotation is set to 60 seconds. Set to `0` to disable key rotation.  
*Required*: No  
*Type*: Integer  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`RepeatExtXKey`  <a name="cfn-mediapackage-originendpoint-hlsencryption-repeatextxkey"></a>
Repeat the `EXT-X-KEY `directive for every media segment. This might result in an increase in client requests to the DRM server.  
*Required*: No  
*Type*: Boolean  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`SpekeKeyProvider`  <a name="cfn-mediapackage-originendpoint-hlsencryption-spekekeyprovider"></a>
Parameters for the SPEKE key provider.  
*Required*: Yes  
*Type*: [SpekeKeyProvider](aws-properties-mediapackage-originendpoint-spekekeyprovider.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
