#2 Re: MIFARE Classic » CRAPTO-1: how to recover key using only ks2 » 2009-05-06 03:36:21

In crapto1 2.2 what the parameter in should be?

struct Crypto1State* lfsr_recovery32(uint32_t ks2, uint32_t in)
Thanks,

#3 Re: MIFARE Classic » CRAPTO-1: how to recover key using only ks2 » 2009-04-15 02:13:58

Why the *len=0;
then   *s = malloc(sizeof(struct Crypto1State) * (*len));
?

#4 Re: MIFARE Classic » CRAPTO-1: how to recover key using only ks2 » 2009-04-15 01:58:16

A question ,
what the len for  for in the funciton recovery . What valud it should be?

lfsr_recovery_32(struct Crypto1State ** s, int *len, uint32_t ks2).

#5 Re: MIFARE Classic » MIFARE Classic clones » 2009-04-15 01:22:31

one of those variations could be the possibility to write all the first sector, and so changing the uid of the card.
Are you sure? what kind of "unlicensed" have the variation?

#6 Re: MIFARE Classic » Crypto1 attack released » 2009-04-11 09:44:47

BTW;
malloc always cann't automatically convert  the according type ,show a error
invalid conversation from void to * (ohter ) error.
I use dev c++  4.9.8
Any setting to avoid this error.

#7 Re: MIFARE Classic » Crypto1 attack released » 2009-04-11 09:16:54

Widmo, I'm also need to know the differency of lfsr_recovery 32 and 64 bits?
It seems that it doesn't work properly, if just modify lfsr_recovery  to 64 .

Hi,Joker
Could you post the method to calculate the 2nd sector's password(using crypto1 we can calculate the first sector)
?
Thanks,

#9 Re: MIFARE Classic » Some mifare traces » 2009-03-20 02:10:28

More trace samples. the first key should be  0x5cfd00c3a302  .
Could you please help me on calculate the block 36 password?
Many thanks

One question .for multi-sector access traces . Is any solution to cal the next sector's password?

I need some help on this.

What 's the problem ?

#14 Re: Trade Parts » Ordering of new proxmarks » 2009-01-14 08:35:20

Have orded ,still wating for the arrivalling.

#15 Re: Trade Parts » anyone got a OPENPCD? » 2009-01-14 08:31:05

Where are you from ? Yes  you can order it ,right now ,it 's out of stock as i know.

#16 Re: Questions and Requests » Unable to flash over USB » 2009-01-14 08:27:34

Just flash it using ulink ,jtag or so, it works.

#17 Re: Questions and Requests » I flashed fpga with fpgaimage.s19 not prox keeps rebooting. » 2008-12-25 11:04:48

fpgaimage should be fashed? as i understanding ,we should only load osimage.s19. then it should go as you like.


FPGA images is loaded by os progrm in osimage?

Is it right?

Hi, i'm insterested in the test .

PS, do you know some detail about INDALA PSK (26bits and 37 bits) cards?

How to get it work in windows enviorment?

thanks in advance.
