Recovering Old wallet.dat Files from 2009

I just dug up my old hard drive and found wallet.dat, but a bunch of files are corrupted. Most of them are unrecognizable too. I’ve been looking for the hex code, and I see a lot of "6b 65 79" but can’t find "04 20". I’m not a tech wizard, so if anyone knows how to recover these files or the private key, I’d really appreciate it.

So you’re saying you lost your keys and can’t track down 420?

Are you using Windows or Mac? Gonna guess you’re on Windows. If so, grab WinHex, just search for it. Unzip it, and if you need help with that, let us know your Windows version. It matters.

I’m in the same boat. I mined coins back in Feb 2009, and honestly, I’m either mourning or trying to recover them. I recently downloaded a 2009 Bitcoin client and ran it in a Windows VM, and it actually found my private key. Just a heads up, don’t use the hard drive until you create a forensic image.

joel.from.minnesota is spot on with that recovery tutorial. Just a warning: don’t mess with that hard drive until you’ve imaged it. Any access could ruin your chances of finding those files.

Quick question: does the WINHEX method still apply if the wallet.dat was encrypted with Multibit Classic back in 2014?

Nah, MultiBit Classic uses a different format. Instead of "wallet.dat", it calls those files "multibit.wallet". So, the WINHEX trick won’t work.

Alright, I’m trying to recover two wallets. One is a Multibit Classic wallet and the other is Litecoin-qt. Will WINHEX help with the encrypted Litecoin wallet?

Honestly, not sure... You might wanna try Pywallet. It can work for other coins too if you set the right parameters. It has a recover mode that scans for wallets and keys.

What if the wallet.dat was disguised as something like a.rar file? How do I run keyhunter.py on Windows 10? I tried and it just crashes.

Are you running the script from the command line or just double-clicking it? Python scripts work fine on Windows 10, you just need to use the command window.

I get it, so I should type./C:\Python27\keyhunter.py <filename>? But if I add a filename like C:\Python27\python.exe C:\Python27\keyhunter.py aaa.txt, nothing happens.

Looking at keyhunter.py, it only shows output if it finds keys. If you’re getting no output, that means no keys were found. It’s looking for a specific byte sequence, so if it’s not there, you won't see anything.

What if I created wallet.dat in version 0.1? How do I check it then?

If you’re on Linux, the script scans the entire disk. But on Windows, you need to create an image of your disk and pass that to the script.

You can use the syntax keyhunter.py \\.\PhysicalDiskN on Windows. Make sure you run the command prompt as an admin.

Nothing’s working, this is frustrating. I’m ready to give up on Linux. Is Assembler from DOS even relevant anymore?

I know this is an old thread, but I’m stuck. Is it possible to find a wallet with keys if it was encrypted? I have the old drive, but I can’t find the wallet in hex.

I think it still uses the same signature bytes. Berkeley DB has entries for "key" and "ckey", which are likely similar in both encrypted and unencrypted formats.

You should really explain your situation better. We have no idea how you might’ve been scammed.
