### Change default SFTP port

Default port '8022' can be changed via

```
--sftp="address=:3022"
```

### TLS (FTP)

Unlike SFTP server, FTP server is insecure by default. To operate under TLS mode, you need to provide certificates via

```
--ftp="tls-private-key=path/to/private.key" --ftp="tls-public-cert=path/to/public.crt"
```
