1  Bitcoin / Bitcoin Technical Support / Re: Old corrupt wallet.dat from when I mined in 2009-2010 on: January 01, 2018, 04:05:17 PM
I have an old corrupt wallet.dat.
I read this so often lately. Files don't get corrupted out of the blue, none of my files from 8 years ago are corrupted now. I've never had old wallets to test it by myself, but what happens if you try to open the old wallet.dat in an old version of bitcoin-qt (from 2009-2010)?

I can't find a binary of an old version like that anywhere

Wondering if you guys could help.  I have an old corrupt wallet.dat.  The contents doesn't look like the standard encryption so I am not sure how to recover it.  The wallet has potentially quite a good number of bitcoins  (potentially over $10M worth) and I have tried just about everything I can think of.

Here is a snippit of what some of the content looks like:

Code:

No idea what to make of it.

I've used CrypTool to play around with it to see if it was some type of encryption I was unfamiliar with.  There is a 3D analysis of the whole file and it certainly doesn't seem entirely random.  It was an older hard drive though and maybe it become corrupt.

Any help would be appreciated immensely
