What OS are you on?

By the way when I run solve_bs on the 0xcafec0de.txt file I get the key 0x626c61003333.
from crypto1_bs.
I cannibalized the mfoc code to put together a nonce collector. Output is also in .txt format. Using that solve_bs now works. I guess that means the issue I'm having is in the nonce collection code in libnfc_crypto1_crack...

Oh, that's strange. I'm glad you figured it out. Hope you can send me back a patch which fixes it for you later on!

I was getting the same issue .. 0xffffffffff returning but it came from that i used the wrong block in argument for libnfc_crypto1_crack !
I believed that i just needed to put the sector i wanted to crack for obtaining key, but Crypto1 really need the correct block to crack the key.. it means block 3,7,11,15 etc ....
Example:
All sectors are using key B a1a2a3a4a5 except sector 8 which no key is found.
I use this command:
./libnfc_crypto1_crack "one known key B" "block of known key" "type of known key" "block you want to crack" "type of key you need"
So
./libnfc_crypto1_crack a0a1a2a3a4a5 3 B 35 B
( block 35 is the adress where it stocks key for sector 8 )
Now i don't have any troubles anymore.. and the better part is that you can obtain either key A or B for all sectors from only one known key .. no matter of its type. =)
Hope i could help ;)

I guess this issue can be closed.
