filegive: Easy sending of files, point-to-point

How to send a file from my computer to my friend's computer, secure, simple and without a third-party in the link? Many people ask this question: xkcd 949. filegive will work, or can be made to work, in many situations.

The receiving side only needs a browser (or anything that can browse using http or https). The sender only needs to call filegive, and give the resulting URL to the receiver by chat, for example.

In fact there is even a 'receiving' mode (-R), so the receiver runs filegive getting a URL that can send to the sender. The sender visiting the URL with a browser is offered an upload html form.

The connection goes point-to-point, and not through a third party server, like, or services like dropbox. Additionally, https provides easy end-to-end security, and extra options like rate limit makes it an improvement over other usual point-to-point methods like dcc send (irc, jabber, ...).

How to use it

In its basic usage, if you want to send a file to your colleague in your network, you simply have to:

$ filegive myfile.webm
Certificate SHA1 (s: filegive tnyoetro): 3B:78:35:7A:58:C0:F3:B4:7C:72:62:11:1A:0D:41:A0:2B:51:8C:67
CA SHA1 (s: filegive egjybhfr): E6:70:74:3B:33:3A:7C:EE:CA:CD:E9:48:8A:3F:AA:CF:0A:38:15:E2

You then only have to send the https url to your friend, and the sending will start. To traverse the Internet, you may need to add some parameters, and maybe configure your network access point. Learn more at Examples of usage.


The SHA1 long lines in the previous example are to be used to achieve security, so noone can see what do you transfer. Filegive uses widely spread cryptography (SSL/TLS) to achieve secrecy end to end, and as it is available in most browsers, it is easier to use and only one side needs filegive installed.

To learn more about the security in filegive, please read the Security page.

Use cases

I wrote this program because I was ashamed not being able to answer how to send a file through the Internet. I have principles, so I couldn't advertise 'dropbox', or 'skype'. At the end, I came up with filegive.

I find it very comfortable in these situations:

All that, without the other side having to be a computer geek to make the transmission effective.

You can Drag&Drop files to the filegive.exe, and it will give you a url. The URL is put on the clipboard automatically, so you can just Drag&Drop the file over it, and paste the clipboard contents into your messaging system.

You can also make a shortcut to filegive.exe adding the "-u" parameter; then Drag&Drop over it will provide a public URL if you have a UPnP-enabled router. Similar for any other configuration required.

Attention: On Windows, using UPnP, you should exit the program typing 'q', instead of ctrl-c or closing the cmd window. Otherwise the UPnP temporary forwarding won't be removed. You'll have a reminder about that running filegive.

To get UPnP working, you may need to tweak your Windows Firewall to let filegive talk with your router.
