Cricktor (fee 10%, bid 0)

What is fee? The 1BTC you offer? I'm not going to bid any real coins as I'm not interested in an auction for this. Or what do you expect as a bid?

This is what I offer and my terms:
I'm willing to execute some exhaustive searches for date formats (search space first attempt 1900-2024 full years, every day will be tried) on mkey hash.

To prove that pffffffff is able to propery extract mkey, salt and iteration count, as described by PowerGlove, I will send him an empty encrypted Bitcoin Core wallet.dat for which I know the wallet encryption password. I will first check that my toolset is working and I'm able to crack the encryption password of this test model wallet.dat. pffffffff can post the hex sequence here in his topic and I will verify and confirm validity.

If this validation succeeds, pffffffff can send me then the hex sequence of the mkey hash for his own wallet.dat that supposedly holds at least 10BTC. pffffffff is solely responsible to handle his wallet best on an air-gapped computer to avoid any compromise of his valuable wallet.

Together with suggestions from pffffffff how his father wrote dates, I will then perform at least the following exhaustive searches (first only in full year's range 1900-2024):
YYYYMMDD, YYYY-MM-DD, MM/DD/YYYY, MM-DD-YYYY, MM.DD.YYYY, DD.MM.YYYY, YYYY/MM/DD,
Jan-Dec MM, YYYY
January-December MM, YYYY and whatever pffffffff else suggests.

I will report back if I succeed or fail. In the case of success, I don't know how to do it safely without risking my reputation here, if something goes wrong on pffffffff's side for whatever reasons.

My first idea was to use an escrow for exchange of 1BTC for the solution. Still this has risks for me if pffffffff screws things up and blames me. I don't want to be negatively flagged for any possible screw-up. I can't verify that the original wallet.dat isn't damaged by any means.

It seems to be safer to simply give pffffffff the solution and hope for the best that he won't scam me. I'm not happy with this either, because pffffffff's account has no reputation. He can go with the full 10BTC without much consequences, because who cares when I flag him that he didn't pay the offered 1BTC.

Maybe I'm overseeing some better solution. Open for suggestions...
