## Overview

Install and manage the haveged daemon.

## Module Description

The haveged daemon provides a random number generator based on the HAVEGE (HArdware Volatile Entropy Gathering and Expansion) algorithm. This module provides a way of installing and setting up the daemon in your environment.

## Setup

### What haveged affects

Package, service and configuration files for the haveged daemon.

* On Debian based systems this includes the `/etc/default/haveged` file.

* On RedHat based systems the configuration is stored in the `/etc/systemd/system/haveged.service.d/opts.conf` file.

### Setup Requirements

This module requires the `stdlib` module.

The `haveged` package is part of the EPEL yum repository, so this repository must be enabled on Enterprise Linux to be able to install the package.

### Beginning with haveged

Declare the haveged class to run the haveged daemon with the default parameters.

```puppet

class { 'haveged': }

```

This installs the haveged package and starts the service using default parameters.

See the following sections for a detailed description of the available configuration options.

## Usage

### Use a higher threshold of available entropy

```puppet

class { 'haveged':

  write_wakeup_threshold => 2048,

}

```
