@noproto do you mind If we add missing part: nfc to mfkey integration?

[skotopes]

Also it does looks like couple APIs is missing

@skotopes That would be very helpful, I've been trying to understand what API could be used to launch it and free the active application (NFC->MFKey, MFKey->NFC on exit if NFC launches it). It would be a seamless process without immediately needing to optimize the NFC app's memory usage.

Should we continue with this one?

Should we continue with this one?

@skotopes @RebornedBrain Yes. Some help is needed with launching the app from the NFC app, along with a return flow. The goal of this PR is to couple the key recovery with the NFC app, similar to hf mf autopwn on the Proxmark. I've been between jobs since we finished PR 3822 which had some unfortunate timing, but I still do plan to progress this series of PRs (and to MFKey directly to speed up static encrypted attacks).

In addition to the improvements we identified in PR 3822, I also am aiming to allow Nested to benefit from the cache file, and to fix a crash with ov-chipkaart. I've ordered an ov-chipkaart card to test with a week ago and it should be arriving shortly. Wr3nch was able to reproduce this crash.

Side note to this PR: I'm creating a new PR soon for an Ultralight C dictionary attack. I already have it running on the Zero, I'm fixing a few minor issues before I PR it. The PR will include almost 50 3DES keys. We are additionally verifying and testing a new practical process to recover keys on UL-C tags.
