Encrypted wallet.dat, lost password, any solutions?

[Revalin]

Is bitcoind in the .bitcoin dir?  To be clear, it needs to be in the directory with the Satoshi client program goes, not the one where the wallet.dat goes.

[Ashitank]

there is bitcoind.pid file in the ./bitcoin directory is this correct.

[Ashitank]

Eh No I have placed brute.rb in directory where my wallet.dat is.

Would you know what is the path to bitcoind directory.

[Revalin]

Did you actually get and install bitcoin?  Try this:

wget http://softlayer.dl.sourceforge.net/project/bitcoin/Bitcoin/bitcoin-0.6.3/bitcoin-0.6.3-linux.tar.gz
tar -xf bitcoin-0.6.3-linux.tar.gz
cd bitcoin-0.6.3-linux/bin/32/
mv ~/.bitcoin/brute.rb .
echo rpcpassword=somerandomjunk > ~/.bitcoin/bitcoin.conf
./bitcoind -daemon

... wait a minute while it starts up ...

ruby brute.rb

And it should start cracking.

[Ashitank]

Trying above steps.

get this error on starting bitcoind

Try:

mv ~/.bitcoin ~/.bitcoin-old
mkdir ~/.bitcoin
cp ~/.bitcoin-old/wallet.dat ~/.bitcoin
echo rpcpassword=somerandomjunk > ~/.bitcoin/bitcoin.conf
./bitcoind -daemon



edit: Fixed the echo line

Scripts running now Revalin. 

Getting lot of passphrase was incorrect message as we would expect.

I really appreciate your kind help & patience with a Linux newb like my self , if I am able to get my password back I will send you 0.1BTC out of some 2.0Btc in that wallet

[Revalin]

No problem!  I'm always glad to help.

Hello, I'm getting this error for every password attempt when running Revalin's script.

Code:

error: {"code":-32601,"message":"Method not found"}

On further investigation it seems that my version of bitcoind is ancient and I need to upgrade.

OMG. I wonder how much electricity you will burn to get those two BTC back.  Sentimental value I guess?

Hi everyone,

I have exactly the same problem as described here - forgot the password for my wallet. I have tried out Revalins script but sso far I had no luck. There are two issues that possibly prevent me from succesfully using Revalin's script:

1. I am running the script on the laptop I also use for my work (I do not have another computer at the moment. Therefore I can let the script run only at night and on weekends, but there is no possibility to resume the script at the point where it left off.)
2. I tried to add german umlauts (ä,ö,ü) to the character list used in the script, but somehow they were not correctly used.

For the reasons mentioned above I have two questions to Revalin and all other interested:

Would it be possible to implement a resume function (possibly using a protocol of the already tried-out combinations)?
Could you add german umlaut and special characters (Ä,Ö,Ü,ä,ö,ü,ß)?

Any help would be great!

I Lost the Passphrase to my Wallet it only have about 1 BTC is it even worth trying to recover? I have the Wallet.dat file however I have no idea what the passphrase is and I have no clue where to begin as the text document that had my passphrase in was destroyed in the multiple format incident... Should I just start over or try running the script that guy posted in the forum to try Brute Forcing it?

If you know absolutely nothing about the passphrase, it's not even worth trying for 1000 coins. However, you might know something about it without recognizing it, like possible length, characters used and whatnot.

As a side note, you might be able to partially recover the text document you mentioned even after formatting, if you haven't totally wiped the drive. Do you remember any other text in that document?

[DannyHamilton]

. . . I have no idea what the passphrase is and I have no clue where to begin . . .

When someone says "I have no idea what the passphrase is and I have no clue where to begin" they usually still remember something about the password.

Examples:

• Was it less than 4 characters?
• Was it more than 50 characters?
• Was there any punctuation in the password?
• Did it use any capital letters?
• Did it use any lowercase letters?
• Did it use any numbers?
• Did it include any real words?
• How did you create it? (mashed the keyboard? ran a random number generator? some other process?)

Please don't bump really old threads. Someone should split at the bump point, lock the original, and delete this post..

Why?
The information in the thread is not outdated, and splitting or creating a new thread for someone having the same issue months later would just create a lot of threads where the same information is repeated.
I get PM's about this thread several times every month, and have helped some people recover their wallets.

I mangaged to solve my problems on my own:

The issue with the german umlauts seems to have to do with some encoding problems. It dissappeared when I used linux instead of Windows.

I am now running the script brute.rb on a virtual machine provided my Amazon using Linux. After registering for Amazon Web Services (AWS), you can use one of their smallest virtual machine instances ('micro') for free for one year. After starting the bitcoind, you just start the script like this:

ruby brute.rb > log.txt &

It then sends its output to log.txt and you can just logout. It takes quite some time, since the AWS micro instance is rather low on CPU power. An attempt to crack an 8 character password took about one week. However, it is absolutely free; you don't even have to pay for the electricity ...
