Blockchain V0 Recovery Issue - rrossman - 02-03-2025
Hi everyone,
I'm trying to recover an old Blockchain.info (Bitcoin) wallet from many years ago and need some help. After doing some research, I came across this GitHub issue, which suggests that v0 wallets are not cracking correctly due to differences in decryption modes.
I’ve already:
- Retrieved my wallet hash using the blockchain2john script.
- Compiled a list of possible passwords in a text file.
- Run Hashcat with various built-in and third-party rules.
I’m almost certain my password is in the candidate list, but I believe that due to the decryption issue, I haven’t had any success. Based on the discussion in the GitHub thread, it seems that OFB mode needs to be implemented instead of CBC and the encryption rounds need to be decreased to properly decrypt Blockchain v0 wallets. I'm not familiar enough with Hashcat’s internals to make these changes myself, but I’d be happy to pay for assistance—either upfront or as a percentage of recovered funds. If modifying the Hashcat source code to support this is possible, even just a one-off build, I’d greatly appreciate it.
If you're knowledgeable about this and think you can help, please send me a direct message.
Thank you.
