opendrop

There’s also the old work on owlink and opendrop https://github.com/seemoo-lab/opendrop, which reimplement apple’s version of WiFi direct and use it to have a Linux implementation of AirDrop. I guess Continuity’s functionality are based on this as well.

This project is great. Hopefully one day AirDrop is liberated too. https://github.com/seemoo-lab/opendrop looked promising, but it seems stale. maybe one day.

From a UX perspective Airdrop is super nice. I don't know if there are working implementations for other OSs. Just found this here but didn't yet test it https://github.com/seemoo-lab/opendrop (hasn't been updated in 2 years, so maybe not too promising)

No, not at all. Someone even implemented AirDrop in Python before[1]. In fact, nothing ever needs such special hardware. It's a decision of the implementer if they'd like to get fancy and rely on such hardware in their implementation to change its security profile, but the iPhone at the other end or any Apple infrastructure would be none the wiser - they just see that they're getting appropriately signed or encrypted, and neither knows nor cares how that came to be. Use of a hardware security module would just make the process more tamper resistant but would not otherwise change the outcome. 1. https://github.com/seemoo-lab/opendrop

0, this is reverse engineered AirDrop protocol. Implementations have been around for a while, eg: https://github.com/seemoo-lab/opendrop

Eh... there is an open source AirDrop implementation, it's 6 years old now. https://github.com/seemoo-lab/opendrop

From the linked security report in that post https://www.netspi.com/wp-content/uploads/2025/11/google-fea... it seems like they implemented something similar to https://github.com/seemoo-lab/opendrop (which was also used to test interoperablity Also `we welcome the opportunity to work with Apple to enable “Contacts Only” mode in the future` doesn't make it sound like Apple actually helped implement this

For something like AirDrop this will need to be sorted out, but already work occurred to reverse engineer this: https://github.com/seemoo-lab/opendrop Would be cool if an open standard on auth forms on top of this.

Somebody indeed has, but since it uses a custom low-level 802.11 variant, I don't think it's feasible on (at least non-rooted) Android devices: https://github.com/seemoo-lab/opendrop

The (for me) most interesting thing is: why the fuck has no one managed to reverse engineer AirDrop and AirPlay yet, in a way that's mass market compatible? Like, there is OpenDrop but that is dead since five years [1], it was a code dump by some researchers, and there are no client implementations to interact with Apple servers for getting keys, or with registering Find My devices... [1] https://github.com/seemoo-lab/opendrop

Would be cool if we sometime would get https://github.com/seemoo-lab/opendrop as an android app (but it would only work with rooted devices). This would allow to send and recieve files to iPhones from android via Apples Airdrop protocol.

Here’s some apps that actually implement AirDrop, because I believe in truth in advertising! (I can’t be the only one, right?): Linux (seems currently maintained) https://github.com/seemoo-lab/opendrop Android (discontinued January 2023, may have compatibility issues, but still, actually compatible with AirDrop) https://github.com/MoKee/android_packages_apps_WarpShare

The AirDrop (https://github.com/seemoo-lab/opendrop) is there. We just need an app
