New: implementing hf mf hardnested
This implements the attack described in
Carlo Meijer, Roel Verdult, "Ciphertext-only Cryptanalysis on Hardened
Mifare Classic Cards" in Proceedings of the 22nd ACM SIGSAC Conference on
Computer and Communications Security, 2015
It uses precomputed tables for many bitflip properties (not only two as in the paper)
and is therefore quite efficient. To prevent failing it doesn't do
differential analysis with several nonce bytes' Sum(a8) properties (each of them
may be wrongly guessed) - instead it concentrates on one nonce byte and tries all
Sum(a8) property guesses sequentially (ordered by probability). The brute force phase
makes use of aczid's bit sliced brute forcer (https://github.com/aczid/crypto1_bs).
Includes runtime CPU-detection to leverage modern (and old) SIMD instructions
with a single executable.
fix USB descriptors
- indicate compliance with USB release 2.0
- set correct vendor and product IDs
- indicate power consumption (500mA)
- add String Descriptor 0 indicating supported languages
- add String Descriptors for Manufacturer and Product
to ui_overlays.h
add ui_overlays.h to .gitignore
should now compile to whatever qt version you have. (as long as it is
compatible with the overlays.ui file...)
Submitting a well documented Lua script whose purpose is to do
bulk, repeated, sequential programming of RFID tags. Could be useful
for users of the ACCX Open Access 4.0 or other simple RFID systems.
Tags programmed with this would potentially be vulnerabile to bisection
attacks, etc... But honestly, they likely would have been anyway.
To use run from within the proxmark3 client:
```
proxmark3> script run lf_bulk_program.lua -b 1000 -c 5 -f 23
--- Executing: lf_bulk_program.lua, args '-b 1000 -c 5 -f 23'
Press enter to program card 1000:23 (hex: 0020042e07d1)
also fixed a save_restore issue with grid alignments
now save_restoreGB() saves/restores offset values
added macro enumeration of SAVE vs RESTORE for save_restore commands.
add demod data to graph.
some bugs are known:
if you close the graph window data plot will not bring it back.
exiting the application without closing the widget form results in
error.
autocorrect graph y labels are ugly
form has old askdemod tab.
sticky button purpose not defined/labeled well.
doesn't clear s_Buff when new graph loaded or sampled.
probably more...
* Compatibility fixes for Qt5
- make Qt detection in client/Makefile independent of OS
- added -std=c++11 and -fPIC as compiler options (required by some Qt versions, breaks compiling with old ProxSpace environment)
fix missing terminating 0 in my_executable_directory (thanks @iceman1001).
fix warning about const used twice in get_my_executable_path() and get_my_executable_directory().
add parameter for # bits to read
auto get samples after lf read/snoop (don't need to do a `data samples`
anymore)
add safe function to get DemodBuffer
add some lf demod comments and apply new lf_read function instead of
read then get samples.
fixed output bug in lf t55xx config print
fixed small bug in lf t55xx detect during ST check
fix noralsy demod bug (st should be true)
fix sprint_bin_break bug (didn't print last bit)
add a function to save/restore demodbuffer
remove redundant countFC call in PSKDemod
clean up pskclockdetect functions
fix indala26decode bug (end of data sometimes not correct)
improve PSK detection / demodulation
improve NRZ detection
improve t55xx commands & fix a few bugs
add t55xx page1 detection - added it to lf search
added experimental t55xx testmode write

Update/cleanup Makefiles (#265)
- add new target "make mfkey" to build mfkey32 and mfkey64
- include above when "make all"
- fix Qt detection for Kali Linux
- create and use dependency files when building client
- create client/lualibs/usb_cmd.lua from include/usb_cmd.h when building client
- add Windows *.exe files with "make tarbin"
- For the time being don't include Makefile.common in Makefile and client/Makefile
- set com3 as default flashing port for Windows (including mingw)
- remove static targets snooper and cli. Remove their sources as well.

Fixed compile error in MinGW (#260)
* Fixed compile error in MinGW
Some versions of MinGW miss some definitions. In order to be able to
compile I redefined a function and added an explicit include. It is only
a quick workaround, as other people also seemed to have the same
problem. It should be checked whether a better solution is possible.

Refactor parity functions
- get rid of __asm function in crapto1.h, use gcc builtin function instead
- make parity functions available in common directory
