docs: def enc_file(name, out=None, **kwargs):
      '''
      This is a helper function to encrypt a file and return its contents.
  
      You can provide an optional output file using `out`
  
      `name` can be a local file or when not using `salt-run` can be a url like `salt://`, `https://` etc.
  
      CLI Examples:
  
      .. code-block:: bash
  
          salt-run nacl.enc_file name=/tmp/id_rsa
          salt-call nacl.enc_file name=salt://crt/mycert out=/tmp/cert
          salt-run nacl.enc_file name=/tmp/id_rsa box_type=secretbox \
              sk_file=/etc/salt/pki/master/nacl.pub
      '''
      kwargs['opts'] = __opts__
      return salt.utils.nacl.enc_file(name, out, **kwargs)
