Thank you for answering me. If I know that I probably put 10 characters with a capital letter at the beginning and  2 number at the end without knowing what it was, I have a chance to find the password with a script?

1 capital letter == 26^1 == 26
2 digits == 10^2 == 100
7 mixed case == 52^7 == 1028071702528

26 * 100 * 1028071702528 == 2672986426572800

2672986426572800 passwords / 10 passwords per second == 8,470,364 years

Can someone try and help me get my 42 coin wallet to open again. I encrypted the wallet earlier today and then later on wanted to send transaction but now it says password is incorrect. I have tried to get some of the other solutions working from this thread but am finding it difficult.

Any help would be appreciated, thanks

Hi guys, I recently just lost access to my wallet albeit it is a fairly small amount inside, I'd still like to get it back though. I went through this entire article http://www.gobitgo.com/articles/1005/How-To-Recover-Your-Bitcoin-Wallet-Password/ and I have the whole process set up perfectly so I can run the test and it works. I've tried it using my own wallet.hash and wordlist a few times now and it is running properly but it keeps on finishing without actually ending up finding the password are there any suggestions or changes I can make to the script that might make it work? Thank you in advance for any replies. Smiley

Ps: I actually do know very fairly close to what the password should be and it is around 32 characters so that may or may not complicate things.

I did an experiment today and found out something interesting.

This is basically my situation at the moment.

My 42 coin wallet is encrypted and I had generated a 100 character password and then cut and pasted it into a text document, notepad to be precise in Windows. But then later on when I copied and pasted it into my wallet to do a transaction it said there was an error. I have tried and tried with no success.

Anyway I noticed something today. Basically when I made up some test wallets and copied and pasted the text, it worked without a problem but then I noticed in some situations that if I selected the text but my cursor was maybe one or two lines above or below the text when I selected it, then it would fail, so I have a feeling that I have done something similar with my password.

Is it doing this because it has added characters to the text, like page breaks etc?? that I can not see??

I also think when I copied and pasted it the first time around to enter into my wallet to encrypt it, word wrap was on and also the text was wrapped onto the next line. This has probably affected it as well.

Anway that is my problem. Has anyone come across this problem before?

Thanks

Almost certainly, yes.

Quite possibly.

Would guess that you know all the words that are in the password.

There is no way to reset the password. Try hit and trial method

Hi, I'm using the Revalin ruby and works awesome. I lost my litecoin wallet password but I think there might me a combination of two or three words.

The problem is that I usually swap one or two vowels by numbers and I can't remember which of them I did.

I'd appreciate a lot if you help me with the function that, giving a word by parameter, it returns a list of all the words with different combinations, where a might be replaced by 4, e by 3, i by 1 and o by 0. I only need that function, the Revalin code is pretty clear.

I know that is something that I could do manually. I have 2^n combinations, where n is the number of vowels on a word.

This might do what you need:

Code:
password_elements = ['p', ['a', '4'], 'ssw', ['o', '0'], 'rd']

def splat(accum, elements)
  if elements.any?
    [elements.first].flatten.each { |elem| splat(accum + elem, elements[1,999]) }
  else
    test accum
  end
end

splat('', password_elements)

Hi

Can someone help me out, I have written down my multibit wallet password incorrectly.

I know the length of the password and I know what characters are contained in it but the possible combinations could take me all year to manually type out.

the password is structured into two parts a word 1 then word 2. Word 1 could be 'bitcoin' but the b could be a b, B or 3 and the i could be an i, I, 1 or a ! and so on. Then second word follows the same pattern.

Has anyone written a scrypt that could attempt to brute force a password with a similar structure?

The wallet doesn't contain many coins but a small reward is on offer If I can recover the coins

hello, I am trying the method of brute force, using the brute.rb file, and I have installed Ruby, its in my C drive, Ruby 200, I made the brute.rb file, which contains,
#!/usr/bin/ruby -w

passphrase = "what i think my password is"
characters = " !\"\'(),./0:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}"

def test(phrase)
  print phrase, "\t"
  system("./dogecoin-qt", "walletpassphrase", phrase, "40")
  case $?.exitstatus
  when 0
    puts "Found it!  #{phrase}"
    exit 0
  when 127
    puts "dogecoin-qt not found in current dir"
    exit 1
  end
end

# transpose adjacent chars
(passphrase.length - 1).times do |i|
  testphrase = passphrase.dup
  testphrase = passphrase[i+1]
  testphrase[i+1] = passphrase
  test testphrase
end


however after I am doing this for doge, and I have edited the .RB file appropriately, but after I paste, dogecoin-qt -server -rpcpassword=wow -rpcport=22555 into CMD, the DOGE WALLET opens, then I type brute.rb, and nothing happens. Can someone help me figure this out?

In my  dogecoin.conf I have
addnode=95.85.29.144
addnode=162.243.113.110
addnode=146.185.181.114
addnode=188.165.19.28
addnode=195.154.7.113
addnode=195.154.7.114
addnode=195.154.7.115
addnode=62.210.124.137
addnode=78.46.57.132
addnode=62.210.198.42
addnode=62.210.198.44
addnode=62.210.198.47
rpcport=22555
server=1
daemon=1
rpcuser=doge
rpcpassword=wow

Thank you

I've tried really hard to get this working on my mac, installed Xcode, learned the basic in how to use the terminal, installed Git and Homebrew and fiddled around a few days but never got Bitcoind to run on OS X 10.8.5.

Now I'm trying this windows app (on my work-computer -> bad, since boss will fire me if he finds out I have admin-rights on it Smiley) that I just found: Recoinvery.com
However, it seems to crash a lot, so still no luck.
I'll report if I get any luck with it.

I have an armory wallet with 1 BTC in it - 18MBduHLgWmQDMH5UZsrzYDtNnyDha85GT

I have no clue what the password is. I have 2 or 3 general passwords that ive tested numbers and capitals and spacings on and no luck. ive tried the obvious (password, mypassphrase, bitcoinwallet, etc) that might have been inspired at the time over a year ago.

Either i misspelled something or went with a string of characters which I cannot find - I'm giving 50/50 odds on which it could be.

How can i try to bruteforce an armory wallet with windows?

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe

Hi,

I forgot my multibit wallet password. So I have been trying the scripts in this thread. I get the "bitcoind not found in current dir"  response when I run the brute.rb script. I think the problem is that bitcoind does not run when using multibit. Is is possible to use these scripts on windows for multibit wallets? I remember the first 10 characters of about 14 so brute forcing it should be possible right?
I installed ruby using the windows installer and put the multibit.wallet file in the same directory as the brute.rb file.

Any help would be greatly appreciated.

Is that normal that it takes YEARS? I try with windows 7 and it tries 1 passphrase per second so 60/min

Isn't there any real bruter like for .zip files with 2000 passwords per second? Or a GPU bruter  Wink

Hey Revalin, I've got a tip for you if you can help me with my case. I've made a wallet back in April 14 2013 and transferred 10BTC into. However, now I can't access it and I'm pretty sure I typed my password in correctly. I've been trying and trying and eventually gave up. But looking at the BTC price now makes me want to shoot myself in the foot. There's an easy 2BTC in it for you if you can help me gain access back to my wallet. I made a reddit post quite a awhile ago that states more details about me and how I'm an idiot and lost my coins, I'll dig up the link to it if you want to see it.

Basically I need a program that can automate imputting my password guesses (stored in a .txt file) into multi-bit's password field, and then click "unlock".  Multibit would do the actuall deciphering of the aes.json file, I just don't know how to automate something like this.

I guess I could manually copy and paste the 11,000 or so entries by hand, but that would take me months of constant work. Sometimes I wish I learned programming. *sigh*

Let me know.

UG, I could probably whip that up for you except I don't know what a multibit
wallet is. Got a link?

Multibit is just a wallet manager essentially, and one of its features includes an "import wallet" option which allows me to import my blockchain.info wallet (which uses a aes.json filetype as opposed to a wallet.dat) into the program. However, I can't import it without the right password. If there was a way for a script to run all my passwords in my dictionary though that field then I could possible get my coins back.

OR OR OR

If someone could type up a script that does exactly that, but for this https://blockchain.info/DecryptWallet.html

I have the encrypted backup key that I need to guess the password for. It would be pretty easy to know if what was entered is correct, simply because nothing else shows if I enter an incorrect password. Again, I'm offering a bounty on this if anyone helps me successfully.

Here are my lost coins' home https://blockchain.info/address/1FhTGBke8f2vAf86GSXpSTgMCknU8sPxJS .

UG already found a solution, but I whipped-up something that may help
you all with similar multibit wallet issues:

https://www.dropbox.com/s/5rcnx4kknt0t4p5/UnivPWhacker.zip

The package shows it works. Run the testapp, then run the MouseXYScreen app on top
of it. Write down the numbers while hovering over the top textbox and then write them
down for the command button. Exit the mouse app and run the hacking app. Enter the
four numbers you just wrote down and hit go. You will see how all entries from the
pws.txt(must be named this) file get entered. The hacker app should work with a pws.txt
file with up to 29.9K entries and with any app where you need to enter a guess and hit
one button over and over again.  :-D

You may need the VB6 runtime also.

I whipped up a really simple site to help generate lists of guesses and put it on http://lostpassword.info. If you think you have a typo or know the pieces of your password it'll make you a big list of guesses. Last month I lost my password for a few days and wrote a bunch of scripts to help get my BTC back. I'm happy to help anyone else get their coins back so let me know Smiley
