 I am unlucky today. I forget my wallet password. I have tried many times, but I still cannot remember it. Now, I write a dictionary with 200,000 password combinations to crack the password. I still haven’t found out the system’s algorithm of authenticating, processing, and transforming the password. I hope some people who have any ideas to show me some code examples. If you have any good suggestions, I will sincerely thank and repay you if the suggestions work.

Do you roughly remember the password ? Like in the words used? If not, it's generally uncrackable.

Easiest solution is to iterate `bitcoind walletpassphrase` over the dictionary.

You mean a complete password list? IIRC, even with that plus the help of a couple Amazon instances you'll take ages to find it. A 10 password, 62 charset dictionary would span across 3-4k TB's. A 8 word pass with the 62 charset takes 1787 TB in space alone. Not to mention that the passphrase is converted into the AES key by doing  more then 10,000 SHA-256 operations.

You really have *no* idea what password you used? Did you wake up in back-alley this morning? :-)

You seem to be looking for a fast way to crack the encryption. Realize that if someone was able to provide you witih this, it would mean wallet encryption was fatally broken. And all signs says it isn't.

Exactly. Wallet-stealer < wallet.dat encryption.  Wink

I thought he was able to generate a list of 200K possibilities. If that's the case, I see no reason to be suspicious (though you can never know). Feed the list to bitcoind through a bash script and see if any one of them is correct. Good luck.

If you think you know the passphrase but just aren't able to get logged in successfully, there have been successful interventions that have found the right passphrase.  Here are a couple recent examples:
