"""
SSH Import Id
-------------
**Summary:** import SSH id

This module imports SSH keys from either a public keyserver, usually launchpad
or github using ``ssh-import-id``. Keys are referenced by the username they are
associated with on the keyserver. The keyserver can be specified by prepending
either ``lp:`` for launchpad or ``gh:`` for github to the username.

**Internal name:** ``cc_ssh_import_id``

**Module frequency:** per instance

**Supported distros:** ubuntu, debian

**Config keys**::

ssh_import_id:
        - user
        - gh:user
        - lp:user
