An open Apple AirDrop implementation written in Python

OpenDrop: an Open Source AirDrop Implementation

OpenDrop is a command-line tool that allows sharing files between devices directly over Wi-Fi. Its unique feature is that it is protocol-compatible with Apple AirDrop which allows to share files with Apple devices running iOS and macOS. Currently (and probably also for the foreseeable future), OpenDrop only supports sending to Apple devices that are discoverable by everybody as the default contacts only mode requires Apple-signed certificates. We support contacts-only devices by using extracted AirDrop credentials (keys and certificates) from macOS via our keychain extractor.

Disclaimer

OpenDrop is experimental software and is the result of reverse engineering efforts by the Open Wireless Link project. Therefore, it does not support all features of AirDrop or might be incompatible with future AirDrop versions. OpenDrop is not affiliated with or endorsed by Apple Inc. Use this code at your own risk.

Requirements

To achieve compatibility with Apple AirDrop, OpenDrop requires the target platform to support a specific Wi-Fi link layer. In addition, it requires Python >=3.6 as well as several libraries.

Apple Wireless Direct Link. As AirDrop exclusively runs over Apple Wireless Direct Link (AWDL), OpenDrop is only supported on macOS or on Linux systems running an open re-implementation of AWDL such as OWL.

Libraries. OpenDrop relies on a current version of libarchive. macOS ships with a rather old version, so you will need to install a newer version, for example, via Homebrew:

brew install libarchive

OpenDrop automatically sets DYLD_LIBRARY_PATH to look for the Homebrew version. You may need to update the variable yourself if you install the libraries differently.

Linux distributions should ship with more up-to-date versions, so this won't be necessary.

Installation

Installation of the Python package release is straightforward using pip3:

pip3 install opendrop

You can also install the current development version by first cloning this repository, and then installing it via pip3:

git clone https://github.com/seemoo-lab/opendrop.git
pip3 install ./opendrop

Usage

We briefly explain how to send and receive files using opendrop. To see all command line options, run opendrop -h.

Sending a File or a Link

Sending a file is typically a two-step procedure. You first discover devices in proximity using the find command. Stop the process once you have found the receiver.

$ opendrop find
Looking for receivers. Press Ctrl+C to stop ...
Found  index 0  ID eccb2f2dcfe7  name John’s iPhone
Found  index 1  ID e63138ac6ba8  name Jane’s MacBook Pro

You can then send a file (or link, see below) using

$ opendrop send -r 0 -f /path/to/some/file
Asking receiver to accept ...
Receiver accepted
Uploading file ...
Uploading has been successful

Instead of the index, you can also use ID or name. OpenDrop will try to interpret the input in the order (1) index, (2) ID, and (3) name and fail if no match was found.

Sending a web link. Since v0.13, OpenDrop supports sending web links, i.e., URLs, so that receiving Apple devices will immediately open their browser upon accepting. (Note that OpenDrop receivers still only support receiving regular files.)

$ opendrop send -r 0 -f https://owlink.org --url

Receiving Files

Receiving is much easier. Simply use the receive command. OpenDrop will accept all incoming files automatically and put received files in the current directory.

$ opendrop receive

Current Limitations/TODOs

OpenDrop is the result of a research project and, thus, has several limitations (non-exhaustive list below). I do not have the capacity to work on them myself but am happy to provide assistance if somebody else want to take them on.

• Triggering macOS/iOS receivers via Bluetooth Low Energy. Apple devices start their AWDL interface and AirDrop server only after receiving a custom advertisement via Bluetooth LE (see USENIX paper for details). This means, that Apple AirDrop receivers may not be discovered even if they are discoverable by everyone.

• Sender/Receiver authentication and connection state. Currently, there is no peer authentication as in Apple's AirDrop, in particular, (1) OpenDrop does not verify that the TLS certificate is signed by Apple's root and (2) that the Apple ID validation record is correct (see USENIX paper for details). In addition, OpenDrop automatically accepts any file that it receives due to a missing connection state.

• Sending multiple files. Apple AirDrop supports sending multiple files at once, OpenDrop does not (would require adding more files to the archive, modify HTTP /Ask request, etc.).

'opendrop send' results in 'Broken pipe' or 'Connection reset by peer' exception

I'm working through the Use AirDrop on a Raspberry Pi 3 guide using the suggested setup:

• Raspberry Pi 3 Model B
• Raspbian Stretch Lite
• BCM43430A1 Wi-Fi chip

When attempting to send a file from the Raspberry Pi to an iPhone, the phone is prompted with the Airdrop Decline/Accept popup. After pressing Accept on the phone, an Alert pops up with the text "AirDrop from "raspberrypi" Failed" and OpenDrop throws either a [Errno 32] Broken pipe or a [Errno 104] Connection reset by peer exception.

Example stack trace of the [Errno 32] Broken pipe exception:

android app

Hi, is it possible to create an Android app that would enable sharing via AirDrop?

Starting HTTPS server

After $ opendrop receive

"Starting HTTPS server" and nothing else happens

Discovery does not work

I can neither get my laptop discovered nor discover my apple devices from the laptop.

My laptop configuration:

• Arch Linux / x64 / 4.19.46 LTS kernel
• Wireless card: Intel 7260 (I have already used it in a monitor mode with airdump-ng, so it works fine)
• Latest owl from git (I have created an AUR package)

My iPhone SE and iPad Air2 have the latest stable iOS 12.3.1.

I have tried various setups on my laptop:

• Connected to 5 GHz WiFi network (the same as the Apple devices) with NetworkManager. The result seems to be that owl couldn't get any useful information:

  19:21:13 INFO : WLAN device: mon0 (addr 28:b2:bd:3:b9:d9)
  19:21:13 INFO : Host device: awdl0

  19:21:13 TRACE: send MIF
  19:21:13 TRACE: send PSF
  19:21:13 TRACE: send MIF
  

  opendrop on both receive and find (with -d flag) was silent except the initial message.

• Connected to 2.4 GHz WiFi network (reconnected all the Apple devices there as well) with NetworkManager. The result was ERROR: unable to inject packet (send: Resource temporarily unavailable) output from owl.

• Disconnected from all the WiFi networks (the Apple devices are left connected to 2.4 GHz WiFi network). This mode was the most promising, at least I started getting some useful messages on the owl side:

Always get low transfer speed.

Hi, I use build-in raspberry pi zero wifi for receiving file from my friend iPad, My speed is around 0.05 - 0.30 MB/s.

I don't know what cause this or this is normal for opendrop. I think its because I use build in antenna. I plan to buy new wifi usb to boost up my speed.

Avoid pycrypto

Hi there,

This is a really cool project - I wish there was something similar for Android :)

I noticed that you're using pycrypto:

    install_requires=['pycrypto', 'requests', 'fleep', 'netifaces', 'Pillow',
                      'requests_toolbelt', 'ctypescrypto', 'libarchive-c'],

At this point, pycrypto is considered insecure, and even has known exploits (pycrypto/pycrypto#176, pycrypto/pycrypto#253, pycrypto/pycrypto#269).

It's recommended to at least move to PyCryptodome, which should be mostly API compatible. The best solution would be to move to the cryptography library, which is considered best-practice at this point (and recommended by Cryptography — The Hitchhiker's Guide to Python).

Set "Host Name"

Is it possible to set the "hostname" to something other than the actual hostname for receiving files?

opendrop won't find an iphone

I was able to receive files (although I don't know where the file was put), but opendrop won't find the same iphone when attempting to send a file.

I only get this message:

Looking for receivers. Press enter to stop ...

Not all devices are detected/sporadic behavior

Ok, so I am trying to airdrop things to people and I have ran into many issues that might be caused by the lack of BLE support.

•The commands 'airdrop find' and 'airdrop receive' yield no results on these devices:
iPad mini 1, iPad 4th gen (MD511LL/A)
•But it works on these devices:
iPhone 6, iPhone SE, iPhone 7

Although, the devices I've listed working are sporadic regarding recognition; with the devices in question taking multiple minutes for traffic to appear in the logs when I run the command: 'sudo owl -i mon0 -d -v' . This again may be an issue with the lack of BLE support; correct my if I'm wrong.

Conclusion:
Is this an issue on my end? Or is this caused by the lack of BLE support?

P.S
Incase it's useful, here are some misc. info:
Wifi card used for owl/opendrop: Atheros AR9485
OS: Manjaro (unstable branch but I tested on stable aswell)
Command used to put wifi card in monitor mode: 'sudo iw phy phy2 interface add mon0 type monitor flags active && sudo iw wlp2s0 del'

TypeError when running opendrop

I installed opendrop with the command pip3 install opendrop --user and then ran it with opendrop find, but I'm getting this error:

As a side note, thank you so, so much for making this! I've been looking for a way to share files between my devices in an AirDrop-like fashion ever since I started using a Windows machine.

Where are files downloaded?

When using the receive parameter, where are files downloaded?

I got a File(s) received (size 3.17 MB, speed 14.82 MB/s) message but cannot locate any file.

Problems With Find devices

Rpi 4 adapter alfa. I start owl and opendrop dont see apple devices with open airdrop. Can you help me with this problem?

Github release.

Please make a github release, for packaging purposes.
Thanks.

Got "abort" on every command

My environment: macOS 10.15 beta 5, Python 3.7.4.

When I was trying to run whatever command, the application exited:

[1] 49195 abort opendrop

Any clues will be helpful. Thanks.

Random behaviour with opendrop receive

Hi, I've tried in multiple virtual machines with the following configuration the "receive" command with no success:

• Ubuntu 18.04, network card: Alpha AWUS052NH
• Debian 9, network card: Alpha AWUS052NH
• Kali Linux 2019, network card: Alpha AWUS052NH

In all of the environments, I've managed to set up the network with the card in monitor mode, although I have only been able to run the owl process with the -N flag sudo owl -i [iface] -N
When i run the process (both with the daemon process or without it) I've been able to use the opendrop find command all the time, discovering all the devices but when i try to run opendrop receive there are some random issues:

• Most of the time it does not work, freezing and sending random zerconf mdns packets but not receiven anything.
• Sometimes it captures the devices and my iDevices display the new device created by opendrop with the given name.
• Sometimes it captures the devices but it does not appear in my iDevices.

So I don't know what to do to fix those issues.
Thanks in advance.

Code restructuring

Hello, I was wondering if you would be ok with me changing the setup files to current standards, so that the main config entries, such as requirements, script name, entry point, are in the setup.cfg.

Also using click library instead for CLI

TypeError: LoadLibrary() argument 1 must be str, not None

I installed opendrop-0.10.2, and there's is a TypeError occurred when I tried to find devices.

How to generate the Apple pem certificate

How do you generate (get) the apple_root_ca.pem certificate?

Missing pip3 dependency: netifaces

After install opendrop frompip3 on macOS I've get error:

ModuleNotFoundError: No module named 'netifaces'

So i need to install this module manually:

pip3 install netifaces

and then it works. Probably this module should be added as dependency on pip scripts.

After installing it says "opendrop: command not found"

is there any solution to it?

Discovering "Contacts Only" devices

Not really an issue, but just a question. Possibly a dumb one, as I'm rather inexperienced when it comes to cryptography, certificates and signing keys. Forgive me for that in advance. I should also mention I'm playing with OpenDrop on macOS, running on top or native AWDL, no OWL involved, although I don't think it makes any difference for this particular question.

If I read correctly, what I can understand from this paper (section 3.3) and OpenDrop source file util.py, (line 94), in order to discover and send files to a device in Contacts Only mode, two certificates are needed. The first one is a device-specific Apple-signed certificate, with subject name something like com.apple.idms.appleid.prd.uuid, where uuid part is an Apple ID account UUID. The certificate is usually placed into user's login Keychain when logging into the device with its Apple ID. The whole purpose of this certificate is to get that UUID (and put it into the record data) and if one can figure out some other way of doing it (e.g. using Apple's private Sharing framework), that certificate is not needed at all.

The second certificate is used to sign binary plist data of created record data. It is said that "to be accepted by Apple clients, we would need the Apple-owned private key of the signing certificate", and of course we don't have it. When my Apple AirDrop devices in Contacts Only mode are discovered by my Mac, I assume the record data containing my Apple ID UUID and hashed contacts is somehow signed on the Mac and send to those devices when trying to establish an authenticated connection. So, if there are no Apple-owned private keys on my Mac, I wonder how that record data gets signed when the Mac initiates authenticated connection to other AirDrop device.

Once again, I apologise for potentially dumb question for the reasons I explained in the first paragraph and thanks for clarification.

Actual behavior: same but without an image

Merge changes in `zeroconf` upstream

We should merge our changes to the zeroconf package with upstream as @jstasiak suggested in #8 (comment).

• Solve possible conflicts with work on IPv6 that is already upstream
• Write test cases

wlan0, device can't be found

Whenver I put in
sudo iw phy iw dev wlan0 info | gawk '/wiphy/ {printf "phy" $2}'interface add mon0 type monitor

I get:
command failed: No such device (-19) command failed: No such file or directory (-2)

Sending to multiple devices

I was wondering if there was a plan for sending to multiple devices simultaneously? Or even better, having a argument to either opendrop find or opendrop send that would find a device then automaticly attempt to send a file to it.

Possible example of sending a file to multiple devices:
opendrop send -f "file.png" -n "device name" -r 0,1,2,3,4

Possible example of automaticly finding and sending file:
opendrop find --auto-send -n "device name" -f "file.png"

active monitoring mode

I don't know where to put this so I'll put it here. If your having issues with active monitoring mode try creating a monitoring interface with this command:

sudo iw phy phy1 interface add mon0 type monitor flags active

hope this helps!

I'm using Python 3.7.3 and ctypescrypto 0.5 under OpenSuse Tumbleweed.
So is this a known error or should the code be updated somehow?

Create "opendrop" package for pip installation

Currently the command pip3 install opendrop shows that the package is not registered in the PIP repositories yet, therefore it is easy for someone malicious to claim the package and serve arbitrary code with it.

I suggest the maintainers of this project register it with PIP so it can be installed with above-mentioned command.

Can't discover any devices

I can't discover any devices via the opendrop find command. It successfully starts looking for receivers but then just sits there and can't discover any devices. OWL seems to be working fine, and with wireshark (not wireshark-awdl) I can see packets being sent between other devices.

Is this a problem on my end or a bug/limitation of OpenDrop?
Cheers.

DistributionNotFound

On manjaro I'm getting the following error after installing opendrop-git from aur.

After some googling I can't find where this distribution is supposed to come from. Can you point me to the right direction?

AirPlay 2

Does this support AirPlay 2?

Cant find my iphone

This project looks awesome, but sadly its not working for me.
I installed owl und opendrop, then i set the wifi adapter in monitor mode

$ sudo ifconfig wlx74da38ea5fe5 down
$ sudo iwconfig wlx74da38ea5fe5 mode monitor

After that i started owl

$ sudo owl -i wlx74da38ea5fe5 -N

Anything looks like its working, i get the following output from owl

13:24:08 INFO : WLAN device: wlx74da38ea5fe5 (addr 74:da:38:ea:5f:e5)
13:24:08 INFO : Host device: awdl0

Also the output from opendrop (opendrop find) has no exceptions/error messages

Looking for receivers. Press enter to stop ...

But i never find my iphone (Iphone 11 pro), the same thing is while receive (my iphone dont find my pc).

I hope you can help me out :-)

Triggering AWDL

Triggering macOS/iOS receivers via Bluetooth Low Energy. Apple devices start their AWDL interface and AirDrop server only after receiving a custom advertisement via Bluetooth LE (see USENIX paper for details). This means, that Apple AirDrop receivers may not be discovered even if they are discoverable by everyone.

How do you send this custom advertisement?
I know how to receive it, and how to craft one, but EVERY SINGLE BLE api/wrapper seems to expect you're sending an ibeacon or eddystone and refuses to do otherwise.

Share password via opendrop

Hello, it is possible to share a WLAN password via AirDrop since couple of last iOS versions. Could it be also done with this library?

Why IPv6 is singled out in the error messages?

get_ip_for_interface is described as finding IPv4 or IPv6 address:
https://github.com/seemoo-lab/opendrop/blob/master/opendrop/util.py#L190

but when it fails the error messages say that IPv6 wasn't found:
https://github.com/seemoo-lab/opendrop/blob/master/opendrop/client.py#L44

Why does it talk about IPv6 specifically? Is it required?

is it still working?

Hi, I'm trying to run the opendrop on the my Ubuntu machine 18.04.

I'm using the last owl and opendrop, and airmon-ng to switch the WiFi interface to monitor mode,
for the wifi cards I tried my build-in card from intel and external alfa wifi catds with realtek driver.

I followed this blog https://owlink.org/2019/05/16/howto-use-airdrop-on-raspberry-pi-3.html
and everything install and worked fine.

but "opendrop find" dose not find any devices running airdrop (iPhone IOS 12.3.1)
on the owl shell I can watch some mac address when the phone try to look for airdrop destination but without names.

I tried to change channels on owl but it did not work.
even tried to set the "opendrop receive" and I can not find it from the iphone airdrop.

I'm trying to run it now on RPI Zero but I do not think it will make a difference.
