OK so now that we know that the normal file sharing services are not great when sharing sensitive files
even if the use end to end encryption such as Firefox has sent service in this lecture I want to show
you a more private method to share files.
Now this method is peer to peer.
Now remember we said the main problem was not about encryption but it was the fact that our files were
stored somewhere that we have no control on.
So and the method that I'm going to show you in this lecture our files will not be stored in a server
that we don't control.
It's going to be stored locally.
It's going to be peer to peer so the file will be shared from our computer to the computer of the person
that we want to share the file with.
It's going to use end to end encryption.
It's going to benefit from the anonymity offered by data network.
Therefore it's going to be more private and more anonymous.
And this method we're going to be using a tool called on in share.
And to put this simply the way this will work is it will create an online service on your computer so
others can access this online service and download your file so you can think of it as if it's creating
a dark web web site on your local computer.
And this Web site can only be used to download the files that you specify.
To make this simpler you can think of this the as the user that wants to download your file and we all
have seen this diagram of the Tor network and how when you try to access a hidden service you go over
three nodes the user that you want to share the file with Will and at an online service that is sharing
your file and this online service is running from your own local computer so the file is shared directly
from your computer and you can shut down this sharing service whenever you want whenever you feel that
you don't want to share the file anymore or whenever you feel like your connection is being compromised.
So as you can see in this example we are not uploading our file to a server that we do not own or do
not control therefore it fixes the main issue with the method that I showed you with the Firefox service
and it benefits from all of the encryption implemented by the Tor network.
Therefore it's more private more secure and more anonymous now doing this is actually very very simple
and tells.
So let me show you.
I'm back at my file the manager I have the picture or the file that I want to share right here and all
they have to do is right click this file and click on share via on and share as you can see.
This will open the online share window for you.
You can see the file that I selected is already in here and you can click on Add files to either more
files to share with a specific person you can add a full folder by clicking here and you can use the
delete to delete files.
You can also see the checkbox in here ticked.
Stop sharing automatically.
This basically means once someone downloads this file the sharing will stop automatically.
You can unpick this to keep sharing the file until you manually Stop it.
Once you're happy with the files that you want to share we're going to click on Start sharing.
And right now when you see the yellow dot in here this means that online share is creating and starting
the online service that will share the files for you.
So you want to be patient with this.
It might take some time and wants this is done as you can see the circle will turn green and you will
see a link to a head in service so you can see this looks very very similar to the links that we use
when accessing darknet Web sites you can click on copy or l to copy it and then you can share this link
with anybody that you want to share the file with.
So you can send it via email or you can send it using in an instant message like what I'm gonna do right
now so I'm gonna paste the link in here.
You can go ahead enter to send it and then I'm gonna go to a second computer.
We're gonna pretend that this is the recipient's computer.
As you can see they got a message with a link in here and all they have to do is click on this link.
Now keep in mind this is a hidden service or an online service link so it can only be accessed using
the Tor browser or using a computer that is configured to use the term network.
So this service is only accessible within the Tor network as you can see it wants this loads.
You will get a very simple page.
It has the file name it has the size and if you click on Download it will download the file for you.
I'm going to click on Save and this will automatically go to the Tor Browser directory.
I'm going to click on Save and perfectly download this complete and we can verify this by going here
now as you can see the file has a ZIP format it's not an image and you will always get the file in a
Zip format when using on your and share.
So you have to uncompressed this file and to do that we're going to right click the file click on extract
here and go inside the directory that just got created.
And as you can see we have the image that we wanted to share.
Now if you actually go back to the computer that started sharing you will see that in the status bar.
It's telling us that someone has loaded the download page and that someone has downloaded the file.
So if you actually ticked this box this would have stopped sharing the file automatically because someone
has downloaded the file or if you want to stop it manually you can click on stop sharing to stop sharing.
So now if anyone tries to access this link again.
So if I refresh here you'll see that this page will not load therefore you have full control over the
files that you want to share.
You can start and stop sharing them anytime you want.
The files will not be placed in any computer that you do not have control on.
So it'll only be placed on your computer and you'll benefit from tourists anonymity and privacy.
Therefore this is a much more private method of sharing sensitive files.
