I need your help!
To successfuly recover keys from nested attack we need to correctly predict PRNG value. But we have a problem with that. Due to lack of my knowlege of Flipper Zero NFC HAL, PRNG can jump by quite large values (not like Proxmark3). So app is trying to find a delay where PRNG can be predicted accurately enough. This is not the best option, because we have to try to recover a bunch of unnecessary keys, which takes a lot of time and RAM and also spend a lot of time on timings. I don't know how to fix it.
UPD: Chameleon Ultra devs faced same issue. They seems to use same method: nested.c (better know from the beginning of development...)
How to use it?
