### ssh_authorized_key

Manages SSH authorized keys. Currently only type 2 keys are supported.

In their native habitat, SSH keys usually appear as a single long line, in
the format `<TYPE> <KEY> <NAME/COMMENT>`. This resource type requires you
to split that line into several attributes. Thus, a key that appears in
your `~/.ssh/id_rsa.pub` file like this...

    ssh-rsa AAAAB3Nza[...]qXfdaQ== nick@magpie.example.com

...would translate to the following resource:

    ssh_authorized_key { 'nick@magpie.example.com':
      ensure => present,
      user   => 'nick',
      type   => 'ssh-rsa',
      key    => 'AAAAB3Nza[...]qXfdaQ==',
    }

To ensure that only the currently approved keys are present, you can purge
unmanaged SSH keys on a per-user basis. Do this with the `user` resource
type's `purge_ssh_keys` attribute:

    user { 'nick':
      ensure         => present,
      purge_ssh_keys => true,
    }

This will remove any keys in `~/.ssh/authorized_keys` that aren't being
managed with `ssh_authorized_key` resources. See the documentation of the
`user` type for more details.

**Autorequires:** If Puppet is managing the user account in which this
SSH key should be installed, the `ssh_authorized_key` resource will autorequire
that user.


#### Properties

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

##### `ensure`

Valid values: present, absent

The basic property that the resource should be in.

Default value: present

##### `type`

Valid values: ssh-dss, ssh-rsa, ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521, ssh-ed25519, dsa, ed25519, rsa

Aliases: "dsa"=>"ssh-dss", "ed25519"=>"ssh-ed25519", "rsa"=>"ssh-rsa"

The encryption type used.

##### `key`

The public key itself; generally a long string of hex characters. The `key`
attribute may not contain whitespace.

Make sure to omit the following in this attribute (and specify them in
other attributes):

* Key headers, such as 'ssh-rsa' --- put these in the `type` attribute.
* Key identifiers / comments, such as 'joe@joescomputer.local' --- put these in
  the `name` attribute/resource title.

##### `user`

The user account in which the SSH key should be installed. The resource
will autorequire this user if it is being managed as a `user` resource.

##### `target`

The absolute filename in which to store the SSH key. This
property is optional and should be used only in cases where keys
are stored in a non-standard location, for instance when not in
`~user/.ssh/authorized_keys`.

Default value: absent

##### `options`

Key options; see sshd(8) for possible values. Multiple values
should be specified as an array.

#### Parameters

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

##### `name`

namevar

The SSH key comment. This can be anything, and doesn't need to match
the original comment from the `.pub` file.

Due to internal limitations, this must be unique across all user accounts;
if you want to specify one key for multiple users, you must use a different
comment for each instance.


### sshkey

Installs and manages ssh host keys.  By default, this type will
install keys into `/etc/ssh/ssh_known_hosts`. To manage ssh keys in a
different `known_hosts` file, such as a user's personal `known_hosts`,
pass its path to the `target` parameter. See the `ssh_authorized_key`
type to manage authorized keys.


#### Properties

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

##### `ensure`

Valid values: present, absent

The basic property that the resource should be in.

Default value: present

##### `type`

Valid values: ssh-dss, ssh-ed25519, ssh-rsa, ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521, dsa, ed25519, rsa

Aliases: "dsa"=>"ssh-dss", "ed25519"=>"ssh-ed25519", "rsa"=>"ssh-rsa"

The encryption type used.  Probably ssh-dss or ssh-rsa.

##### `key`

The key itself; generally a long string of uuencoded characters. The `key`
attribute may not contain whitespace.

Make sure to omit the following in this attribute (and specify them in
other attributes):

* Key headers, such as 'ssh-rsa' --- put these in the `type` attribute.
* Key identifiers / comments, such as 'joescomputer.local' --- put these in
  the `name` attribute/resource title.

##### `host_aliases`

Any aliases the host might have.  Multiple values must be
specified as an array.

##### `target`

The file in which to store the ssh key.  Only used by
the `parsed` provider.

#### Parameters

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

##### `name`

namevar

The host name that the key is associated with.
