## Resource types

### apt_key

This type provides Puppet with the capabilities to manage GPG keys needed
by apt to perform package validation. Apt has it's own GPG keyring that can
be manipulated through the `apt-key` command.
**Autorequires**:
If Puppet is given the location of a key file which looks like an absolute
path this type will autorequire that file.

#### Examples
##### here's an example
```puppet
apt_key { '6F6B15509CF8E59E6E469F327F438280EF8D349F':
  source => 'http://apt.puppetlabs.com/pubkey.gpg'
}
```

#### Properties

The following properties are available in the `apt_key` type.

##### `ensure`

Data type: `Enum[present, absent]`

Whether this apt key should be present or absent on the target system.

##### `created`

Data type: `String`

Date the key was created, in ISO format.

#### Parameters

The following parameters are available in the `apt_key` type.

##### `id`

namevar

Data type: `Variant[Pattern[/A(0x)?[0-9a-fA-F]{8}Z/], Pattern[/A(0x)?[0-9a-fA-F]{16}Z/], Pattern[/A(0x)?[0-9a-fA-F]{40}Z/]]`
_*this data type contains a regex that may not be accurately reflected in generated documentation_
