+============================
+
+NAME
+----
+cdist-type__snakeoil_cert - Generate self-signed certificate
+
+
+DESCRIPTION
+-----------
+The purpose of this type is to generate **self-signed** certificate and private key
+for **testing purposes**. Certificate will expire in 3650 days.
+
+Certificate's and key's access bits will be ``644`` and ``640`` respectively.
+If target system has ``ssl-cert`` group, then it will be used as key's group.
+Use ``require='__snakeoil_cert/...' __file ...`` to override.
+
+
+OPTIONAL PARAMETERS
+-------------------
+common-name
+   Defaults to ``$__object_id``.
+
+key-path
+   ``%s`` in path will be replaced with ``$__object_id``.
+   Defaults to ``/etc/ssl/private/%s.pem``.
+
+key-type
+   Possible values are ``rsa:$bits`` and ``ec:$name``.
+   For possible EC names see ``openssl ecparam -list_curves``.
+   Defaults to ``rsa:2048``.
+
+cert-path
+   ``%s`` in path will be replaced with ``$__object_id``.
+   Defaults to ``/etc/ssl/certs/%s.pem``.
+
+
