Title: Need some help with recovering one of my old wallets Post by: bitcoinhelper on July 08, 2019, 09:13:29 AM It's been a while since I've been a part of the bitcoin project. Got extremely bitter after Gox collapsed since I had 90% of my holdings on there. After a recent attic cleaning, I found my old drive, which is supposed to have the other 10% (I believe it was in the thousands of bitcoins, definitely more than one thousand, not exactly sure). I tried every possible password combination I could remember, but it didn't work. The only thing I know for sure is that the password is 10 characters long.
This isn't feasible for me to bruteforce on my home computer, so I was wondering if anybody has experience with smarter algorithms that would be able to decode my wallet passphrase in a shorter amount of time (I'm hoping within a week or so). I've been in a financial crunch recently, and to be honest, had mostly forgotten about cryptocurrencies, so finding my old drive was a very welcome surprise. Feels good to be back in the game. Also, if anyone has contacts with some good wallet recoverers, please let me know, and I will do my best to arrange for an in-person meeting. Title: Re: Need some help with recovering one of my old wallets Post by: bob123 on July 08, 2019, 09:19:39 AM One option would be to use a trusted wallet recovery service (e.g. https://walletrecoveryservices.com (https://walletrecoveryservices.com)).
You don't explicitly need to give your wallet away. Especially do not answer newbies which claim to help you. Further there are some 'professional' wallet recovery services around here which seem to be not that professional at all (i.e. Trying to sound professional, but sharing way too many misinformation). I would suggest to be careful and not answer anyone via PM. Also don't trust every recovery service which had success in recovering a few wallets.

Will be keeping that in mind. I've already received quite a few PMs offering help and asking to purchase the drive!! Not selling for $50, haha... I will contact Dave. Title: Re: Need some help with recovering one of my old wallets Post by: DaCryptoRaccoon on July 08, 2019, 11:37:16 AM My advice would be to sit down with a paper and pen and start to write out things that you can re-call about the time you put your drive away.
Write down possible passwords you used around that time, make a list of attempted passwords you can strike off the list. Try jog your memory of around this time (sometimes old accounts help to job memory) How is the drive protected? Is the drive encrypted? or just password protected? Do you know what the password protection software is used on the drive? Another possible way to do this is if you know most of the password used you can generate a list of passwords possibility. I have included below a small python project that will allow you to generate a list of potential passwords from some input it may help in the process. The Code.. you can edit the code to add special characters or numbers if you can recall any parts of the password this might also help cut down the attempts required. Code: """ How It Works... Code: /Desktop$ python pass.py this will throw a bunch of possible passwords to the output-passwords.txt file for you to try you can bump the option -l for more complexity in the passwords returned. As above do not answer to any PM's telling you they will fix it they are scammers.

Since you seem a bit unaware of the size of your holdings you should first parse the wallet file to see if there is any bitcoin at all. There are several tools on github, easiest to use is pywallet, you can get it https://github.com/jackjack-jj/pywallet If you decide to crack it yourself try btcrecover (also on github) or if you have access to gpus get hashcat , you can read more about hashcat at hashcat.net If you want to know more I will be doing a keynote regarding wallet recovery at malta blockchain summit in a few months (as I did in May with Ledger CEO) ps. even with a decent rig a 10 character password will take a while, so your best bet is using a dictionary attack with some basic rules, or seup btcrecover to do variations of the passwords you believe you used. /KX Title: Re: Need some help with recovering one of my old wallets Post by: bob123 on July 10, 2019, 06:22:40 AM There are several tools on github, easiest to use is pywallet, you can get it https://github.com/jackjack-jj/pywallet Worth to note: Do NOT use pywallet on your file without backups. The chance exists that the file won't be accessible / readable anymore after you run pywallet on it. There already were several cases. Always have one (or multiple) backups of your wallet file before trying to use some tools to gain access to your private keys.

This only happens if you name the output file same as input, don't spread FUD. I have read the source code, pywallet does NOT tamper with the original file. |
