OpenDrop
An open Apple AirDrop implementation written in Python
...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. 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.
