Bitcoin wallet.dat hash - token length exception - jamesyoung - 01-18-2021
I can't figure out what's going wrong when trying to match a password with a Bitcoin Core wallet hash.
I have tried Googling and read some posts here, but so far no luck.
Here is what happens:
Code:
james@john:~/john/run$ hashcat -a 0 -m 11300 ~/wallet_hash.dat ~/wordlists/words.txt
hashcat (v5.1.0) starting...
* Device #1: Not a native Intel OpenCL runtime. Expect massive speed loss.
You can use --force to override, but do not report related errors.
OpenCL Platform #1: The pocl project
====================================
* Device #1: pthread-Intel(R) Xeon(R) CPU, skipped.
OpenCL Platform #2: Intel(R) Corporation
========================================
* Device #2: Intel(R) Xeon(R) CPU, 4003/16013 MB allocatable, 4MCU

Stopped: Mon Jan 18 02:46:38 2021Here is the hash: $bitcoin$64$9269f788d7bcecd411d95cc222c9f0cdf7ebfc6fa33847607f7b8c1338a2c3f8$16$10cb87989a39ef71$60692$2$00$2$00$2
I created the hash with bitcoin2john.py from Openwall's John the Ripper repo.
Any clues on why this hash isn't being recognised as a valid wallet.dat hash?
Thanks for any help!

Curiously, this worked fine on my laptop with the latest version of hashcat.
It didn't want to work at all on a Google compute instance. I tried the Ubuntu 20.04 LTS version, 5.1.1, and the latest version from hashcat, both of which gave errors.
With the latest version, clCreateContext(): CL_DEVICE_NOT_AVAILABLE. hashcat freezes up when running ./hashcat -I and doesn't stop. I have to send CTRL+C to stop it.

You are missing a $00 in the end after that $2 at east in my hashes there is that always..

Or remove the 2 on the end. It looks like the last number 2 should not be there.
