Secure File Transfer Between Ubuntu Machines

I would like to know how to transfer securely files in Ubuntu. Right now there is no integrated utility tool that can facilitate that.

If I search online there results are ssh or samba.

I discovered this nifty tool

It is simple and secure

What can be done to make file transfers in Ubuntu convenient and no brainer?

I’ve moved this to the category because this site isn’t designed to take tech support questions. Sorry. I’d recommend using one of the official support channels listed on the page.
