Hi,  
i am using nodered-contrib-ftp-client to send files to ftps server.  
This server use selfsigned certificate.  
This is returning an 'Error: self-signed certificate".  
how to solve that ?  
Here is a test exemple:

```auto
[
    {
        "id": "e2299cfa34e269e6",

                "vt": "str"
            }
        ],
        "repeat": "",

You can try using the msg.secureOptions and set the ca to the cert present by the ftp server.  
I dont't now how this work, but [here](https://nodejs.org/api/tls.html#tlscreatesecurecontextoptions) it is mentioned that it can be a string

```auto
msg.secureOptions = {
   ca: <<PEM String>>)
};

```
