May be i can use other utils to try extract hash ? Thanks
RE: Hash extract error - philsmd - 03-07-2020
It probably would make much more sense to report this problem to the bleeding-jumbo JTR repository (https://github.com/magnumripper/JohnTheRipper ) where the bitcoin2john.py utility is being developed.
My only recommendations are:
- try to generate a new wallet for which you have the password and without balance and can still reproduce the problem
- try with newer/older versions of bitcoin2john.py (https://github.com/magnumripper/JohnTheRipper/commits/bleeding-jumbo/run/bitcoin2john.py)
- try to search for similar issues here: https://github.com/magnumripper/JohnTheRipper/issues and if no issues are still open, try to report it with a throw-away wallet file attached
- try to use python 2.7 vs python 3.x
all of this is more or less a 3rd party problem, because the hash extraction in this case is done with a JTR tool called bitcoin2john.py (so you are better off reporting it where the roots of that 3rd party are)

Sure i will do this, and will reply here about results.
But i also wonder - Are there other utilities available for hash extraction
-------------------------------
Solved:
Last release of JTR contains old bitcoin2john.py file
I just take this directly from github source and all works fine!
