nfc-iclass's Introduction

nfc-iclass

iClass / Picopass tool for libnfc

A CLI tool for reading and writing HID iClass (Picopass) Access Control cards.

Building & Installing

git submodule update --init
autoreconf -vis
rm -rf build && mkdir build
cd build
../configure
make
sudo make install

Running

Default behaviour is to dump APP1.

For more options:

nfc-iclass -h

Usage: ./src/nfc-iclass [options] [BINARY FILE|HEX DATA]

  Options:

	-c <KEY>      Use CREDIT KEY Kc / APP2 (default is DEBIT KEY Kd / APP1)
	-C <?|CARD>   Create CONFIG card (? prints list of config cards)
	-d <KEY>      Use non-default DEBIT KEY for APP1
	-e            AUTH KEY is ELITE
	-h            You're looking at it
	-k <KEY>      Keyroll KEY for CONFIG card
	-n            Do not DIVERSIFY key
	-o <FILE>     Write TAG data to FILE
	-r <KEY>      Re-Key with KEY (assumes new key is ELITE)
	-R <KEY>      Re-Key to non-ELITE
	-w <BLOCK>    WRITE to tag starting from BLOCK (specify # in HEX)

	If no KEY is specified, default HID Kd (APP1) will be used

Examples

Use ELITE key for APP1:

	nfc-iclass -d DEADBEEFCAFEF00D -e

Dump contents of APP2:

	nfc-iclass -c 0DC442031337D00F

Write APP1 blocks 8 & 9:

	nfc-iclass -w 8 aabbccddaabbccddaabbccddaabbccdd

	nfc-iclass -w 8 /tmp/iclass-8-9-dump.icd

Re-key to ELITE key:

        nfc-iclass -r deadbeefcafef00d

Revert to default iClass Kd (note re-key to NON-ELITE with -R)

        nfc-iclass -d deadbeefcafef00d -e -R AFA785A7DAB33378

Show available CONFIG cards:

        nfc-iclass -C ?

Create CONFIG card AV1:

        nfc-iclass -C AV1

Create KEYROLL card:

        nfc-iclass -C KRE -k F00FBEEBD00BEEEE

Config cards

iClass readers can be reconfigured using CONFIG cards. These will normally be provided free of charge upon request but as we now have the master Kd it's easy enough to dump the set and recreate them at will.

The available cards are:

  AV1:	Audio/Visual #1 - Beep ON, LED Off, Flash GREEN on read

  AV2:	Audio/Visual #2 - Beep ON, LED RED, Host must flash GREEN

  AV3:	Audio/Visual #3 - Beep ON, LED Off, Host must flash RED and/or GREEN

  KP1:	Keypad Output #1 - Buffer ONE key (8 bit Dorado)

  KP2:	Keypad Output #2 - Buffer ONE to FIVE kets (standard 26 bit)

  KP3:	Keypad Output #3 - Local PIN verify

  CSN1:	Mifare CSN #1 - 32 bit reverse output

```
  CSN2:	Mifare CSN #2 - 16 bit output
```
```
  CSN3:	Mifare CSN #3 - 34 bit output
```

  KRD:	Keyroll DISABLE - Set ELITE Key and DISABLE Keyrolling

  KRE:	Keyroll ENABLE - Set ELITE Key and ENABLE Keyrolling

  RSTR:	Reset READER - Reset READER to defaults

  RSTE:	Reset ENROLLER - Reset ENROLLER to defaults

Note that a config card is slightly different from a standard one in that APP1 uses more blocks. This matters for KEYROLL cards as they need the extra space to store the new keys. Other types may work on a standard card but the most reliable method is to use an existing config card and overwrite it.

nfc-iclass's Issues

Compilation Errors under MinGW

In trying to compile under Windows, I've run into a couple of issues. Some I've been able to workaround, and some I have not.

The pkg-config seems to be unable to detect that libnfc is installed so I have to manually edit some library paths to point to the right /libnfc/include folder and all is well eventually.

err.h is not a supported header under Windows, but it doesn't seem to be actually used by nfc-iclass so commenting that out seems to resolve that issue, but this is the compilation error I cannot resolve:

make[2]: *** [Makefile:404: nfc-iclass.o] Error 1

I understand this is probably not something that was tested to compile under Windows, but I would be happy to help test any proposed fixes as needed. I've also compiled this successfully under an Ubuntu VM but for some reason performance with a PN533 seems to be really spotty and tags only detect intermittently.

Additional config cards

no tag was found - "libnfc.driver.acr122_usb Command Code verification failed"

My ACR122U-A9 is working for mifare related stuff, but I cannot seem to make it work for ICLASS.
I verified my ICLASS legacy tag on a proxmark to make sure it is not the tag that is the problem.

Any ideas on troubleshooting this issue?

Based on the following, I tried one of the suggested fixes, which did not work either.
