  The `~certbot_dns_cloudxns.dns_cloudxns` plugin automates the process of
  completing a ``dns-01`` challenge (`~acme.challenges.DNS01`) by creating, and
  subsequently removing, TXT records using the CloudXNS API.
  
  
  Named Arguments
  ---------------
  
  ========================================  =====================================
  ``--dns-cloudxns-credentials`  `          CloudXNS credentials_ INI file.
                                            (Required)
  ``--dns-cloudxns-propagation-seconds``    The number of seconds to wait for DNS
                                            to propagate before asking the ACME
                                            server to verify the DNS record.
                                            (Default: 30)
  ========================================  =====================================
  
  Credentials
  -----------
  
  Use of this plugin requires a configuration file containing CloudXNS API
  credentials, obtained from your CloudXNS
  `API page <https://www.cloudxns.net/en/AccountManage/apimanage.html>`_.
  
  .. code-block:: ini
     :name: credentials.ini
     :caption: Example credentials file:
  
     # CloudXNS API credentials used by Certbot
     dns_cloudxns_api_key = 1234567890abcdef1234567890abcdef
     dns_cloudxns_secret_key = 1122334455667788
  
  The path to this file can be provided interactively or using the
  ``--dns-cloudxns-credentials`` command-line argument. Certbot records the path
  to this file for use during renewal, but does not store the file's contents.
  
  .. caution::
     You should protect these API credentials as you would the password to your
     CloudXNS account. Users who can read this file can use these credentials to
     issue arbitrary API calls on your behalf. Users who can cause Certbot to run
     using these credentials can complete a ``dns-01`` challenge to acquire new
     certificates or revoke existing certificates for associated domains, even if
     those domains aren't being managed by this server.
