the idea is to have a statistically solid conclusion if tag does or does not have the NACK bug.
-in short, ref https://github.com/iceman1001/proxmark3/issues/141
NACK bug; when a tag responds with a NACK to a 8 byte nonce exchange during authentication when the bytes are wrong but the parity bits are correct.
This is a strong oracle which is used in the darkside attack.

--adjusted to fit iceman fork and latest enhancements to LF
(untested)
FIX: some calls to deviceside demods, use 0 instead of reference.
ADD: timeout after n cycles of simulating
CHG: flasher - removed unneeded parameter to function
CHG: flasher - increased limit to fpga-files that can be loaded
FIX: main client, wrong windows define fixed.
CHG: device side - recieve usb command does not always get 544 bytes. usb packages can be incomplete.
CHG: usb_cdc.c also got piwi's changes.
CHG: uart_posix.c removed a debug value
CHG: uart_win32.c clean up.
Using a dictionary file with 421keys,
Current implementation of checkkeys takes 300 sec.
This implementation of checkkeys takes 250 sec.
I implemented it as a separate command so it will be easier to compare between the old and new checkkeys.
Its also doing much on deviceside, which is a step to much funnier standalone modes :))
fix: 'hf mf hardnested' test cases doesn't need to verify key.
add: 'hf mf ' - collect nonces from classic tag.
chg: switch_off on armside, a more unified way, so we don't forget to turn of the antenna ...
chg: renamed 'hf iclass snoop' into 'hf iclass sniff' in an attempt to make all sniff/snoop commands only SNIFF
chg: 'standalone' -> starting the work of moving all standalone mods into a plugin kind of style, in its own folder.
'hw version' - added a function to print out which mods is installed on the firmware (deviceside)
New compiler flags are:
# -DWITH_ICEMAN
# -DWITH_LF_SAMYRUN
# -DWITH_LF_PROXBRUTE
# -DWITH_LF_HIDCORP
# -DWITH_HF_YOUNG
# -DWITH_HF_MATTYRUN
The code behind them are NOT in this commit. They will come in there own files later on.
- armsrc/Makefile when commenting out functionality, move it below the comment otherwise APPS_CFLAG breaks to early. See WITH_LCD
- common/Makefile.common enable / disable EMV, uncomment two lines. then make clean && make all. flash, MIGHT NOT work on 256kb devices
FIX: missing break in appmain.c made it go to iclass function..
- `lf em4x readwordPWD` merged into `lf em4x readword` See help text
- `lf em4x writewordPWD` merged into `lf em4x writeword` See help text
- `lf em4x readword` now download the collected signal data after command.
On device side the lfops.c has gotten some love. Code cleaner, increased EM_START_GAP from 55 FC to 56 FC, because of how our microsecond(us) clock works with 21.3us increments.
TODO: `lf em4x em4x50read` needs to be factored to use @marshmellow42 's ASKdemod instead of trying to do itself.
CHG: call params to selectcard too few
CHG: 'standalone HF mode' - when copying second UID onto data array, it should append after first one, not over the first one.
ref: https://github.com/iceman1001/proxmark3/issues/77 Lets see if this fixes the HF part of this issue
Added a lot of #ifndef , extern C,
Move inside from ARMSRC -> THUMBS, which made the compiled image smaller.. I don't know if it broke anything.
Moved MF_DBGLEVEL definitions into common.h
Moved print_result from util.c into appmain.c
Also split up some struct typedef into header files so they could be reused in other code places.
''' danger ''' this might have broken stuff...
I also made the SRi read functions better by combining them. The demodulation / uart code should be the same as last summers changes. The device side code can now be even smaller.
CHG: Minor code changes on T55X7 code. Default password is back to 'FF FF FF FF',
REM: removed @marshmellow42 's wakeup option in "lf t55x7 read",
--- BASICALLY:
if a T55X7 tag has following bits set:
AOR - send wakeup command with pwd, to enable LF interacting with it.
PWD - send read/write/trace/info command with pwd. No need to send wakeup.
ADD: Added the "lf t55x7 wakeup" command. It will send a pwd, and leave the antenna on.
Process like:
1. lf t55x7 wakeup p 11223344
2. lf search
---
It is still not finished, will work together with the "lf t55x7 commands" in next step when I figure out the process from the datasheets.
ADD: @marshmellows "diphase" definition for T55x7.
MOV: extracted the aquisition from the t55x7 methods and put them inside lfsampling.c
FIX: pcf7931 write, there is 16bytes in a block.. not 4 as I thought before.
FIX: t55x7 lowered the WRITE_0 to 16. Even bigger gap.
Things like the ICLASS, tryDecryptWord,
--
My other stuff like default keys, some new Mifare EV1 commands 0x40, 0x43 for the logging annotation, start of the T55x7 configblock helper functionality (ripped from Adam Lauries RFIdler code)
Changes to the PCF7931 functions written, which has a lousy input check..
.. ntag simulation stuff from @marshmellows branch "ntag/sim"
.. hf mf mifare fixes from @pwpivi.
.. hw status command
.. speedtest function from @pwpivi
.. Viking Functionalities, (not a proper DEMOD, but a start)
.. GetCountUS better precision from @pwpivi
.. bin2hex, hex2bin from @holiman
...
starting with getting the T55x7 CONFIGURATION_BLOCK for different clone situations. Ripped from Adam Lauries RFidler, nothing working or finished..
...
Started working with the T55x7 read command with password actually performs a write block... See Issue #136https://github.com/Proxmark/proxmark3/issues/136 Not solved yet.
...
Started add SHA256.. not working yet..
MERGED: @piwi changes
MERGED: @marshmellows changes.
I'm not even gonna try write up all that stuff..
ADD: changed some commands inside the "Hf 14a sim" on deviceside.
ADD: @mobeius "two nonce" version for mfkey32. It is also inside the "hf 14a sim" with the "x" parameter.
CHG: Merged the "hf mfu wrbl" and "hf mfu cwrbl" commands into "hf mfu wrbl". One write command.
Both new commands implement a help, authentication (0x1A/0x1B) for ULC and the rest,
NEW: HF MFU SETUID - set UID to a magic UL / UL-C tag. *not implemented*
CHG: minor alignment for "Hf list" output.
CHG: removed unneeded function parameters to the ultralight commands
CHG: the const MAX_MIFARE_FRAME_SIZE is changed to MAX_FRAME_SIZE in the ultralight commands since the UL-Ev1 can have bigger frames than 18bytes.
CHG: adding DES support for the Ultralight-c read commands on deviceside.
applies icemans full ata55x7 read/write settings
adds checksum to ioprox (thanks to iceman)
adds silent mode for lf read and getSamples
fix lf em em410xwatch and lf em410xspoof
improve data rawdemod ar - for biphase demods
improve detectclock a for strong antennas
- provided a BigBuf_malloc() function to dynamically allocate parts of BigBuf
e.g. for DMA-Buffers, Frame-Buffers, Emulator-Memory
- the whole rest of BigBuf is now available for traces (instead of a small fixed amount)
- send actual traceLen together with trace data
- changed client side to cope with varying traceLen
- changed small buffers to automatic variables instead of parts of BigBuf
ADD: added a manufacturer list in "hf 14a reader", only viable when UID is double or triple size. Thanks to Asper for the list.
ADD: detect chinese magic backdoor commands in "hf 14a reader"
CHG: minor code clean up.

fixed a few bugs in lf demod that the streamlining added. added new lf
em em410xdemod command that loops until button pressed. (similar to lf
hid fskdemod
- unified hw tune and Enio's great data tune
- don't use BigBuf (and hardcoded Offset)
- removed special handling of CMD_MEASURED_ANTENNA_TUNING
in UsbCommandReceived()
Applied PwPiwi's new parity fix.
Applied Marshmellw's fixes for FSKdemod (HID, IO)
FIX: a potential bigbuffer fault given pwpiwi's change inside lfops.c CmdIOdemodFSK & CmdHIDdemodFSK
FIX: change some "int" parameters to uint's.
FIX: changed the lfops.c - DoAcquisition125k_internal to respect pwpiwi's definitions of FREE_BUFFER_OFFSET
HEADS up: The ultralight functions hasn't been verified since pwpiwi's changes.
