Error while collecting nonces #8

Closed khalil00 closed 8 years ago

I'm getting this error using libnfc_crypto1_crack : 

# ./libnfc_crypto1_crack b0b1b2b3b4b5 0 B 1 BFound tag with uid fbfed8c2, collecting nonces for key B of block 1 using known key B 0000ffffffff for block 0

I think that the problem is known key parameter is not correctly read from program args. I have tested with both ACR122U and SCL3711 readers but same result. (compiled with libnfc 1.7.1 under kali linux)

found the problem! replace this : known_key = strtoul(argv[1], 0, 16); by known_key = strtoull(argv[1], 0, 16);
