Hi,

Just installed a bitcoin client, create a wallet, and tried to run bitcoin2hashcat(/john).py :

Code:
python bitcoin2hashcat.py  default_wallet.dat
ERROR:root:Couldn't open wallet.dat/main. Try quitting Bitcoin and running this again.

Why? Bitcoin is not running.
Thanks.

Could be anything. The file may be damaged or maybe a slightly different format is used in newer versions of bitcoind.

I tried 4 different desktop bictoin clients.
So I guess the format is different!

Ok Smile I tested with other clients.

With the latest BitcoinCore, I have another error:


Code:
python bitcoin2hashcat.py walC.dat

Traceback (most recent call last):
  File "bitcoin2hashcat.py", line 638, in parse_wallet
    d.update(parse_BlockLocator(vds))
TypeError: 'NoneType' object is not iterable
ERROR parsing wallet.dat, type bestblockkey data:       bestblockkey data in hex: 0962657374626c6f636bvalue data in hex: 6471020000


Works ok with bitcoin2john:
Code:
python bitcoin2john.py walC.dat

WARNING: walC.dat has previously unseen minversion '159900'!

From what I can tell bitcoin2john.py should be compatible with hashcat. Can you try and confirm?
