1) Go to http://rubyinstaller.org/downloads/ and download Ruby 2.0.0-p353. Once the file has downloaded, run the installer. Restart your computer.

2) COPY the code below and paste it into Notepad. Save the file as brute.rb (including the quotation marks this is so Notepad doesn't automatically save it as a .txt.) Make sure the file is in the same folder as your protoshares-qt.exe file (this is for convenience later).

The following code is modified very slightly from the original code written by Revalin, but since he doesn't charge for his services, I hope he doesn't mind me using his code for this tutorial.

Code:

#!/usr/bin/ruby
require 'base64'
require 'digest/sha2'
require 'open3'
require 'openssl'
# Put your best guess at your passphrase here
passphrase = 'Oops I forgot'
# The full path to your Protoshares wallet file
wallet_file = ''
# Where to find Protoshares-qt client.
$protoshares = ''
def test(phrase)
$cipher.reset
$cipher.key = Digest::SHA256.digest(Digest::SHA256.digest(phrase))
$cipher.update $seed
$cipher.final
puts phrase
i,o,t = Open3.popen2e($protoshares, "-o", "getseed")
i.puts(phrase)
i.close
if t.value.success?
  puts "Found it! #{phrase}"
  exit
end
rescue OpenSSL::Cipher::CipherError
end
def scramble(passphrase)
characters = " !\"\#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~"
list = []
# transpose adjacent chars
(passphrase.length - 1).times do |i|
  testphrase = passphrase.dup
  testphrase[i] = passphrase[i+1]
  testphrase[i+1] = passphrase[i]
  list << testphrase
end
# delete one char
passphrase.length.times do |i|
  testphrase = passphrase.dup
  testphrase = testphrase[0,i] + testphrase[(i+1)..-1]
  list << testphrase
end
# substitutute one char
passphrase.length.times do |i|
  characters.chars.each do |c|
   testphrase = passphrase.dup
   testphrase[i] = c
   list << testphrase
  end
end
# insert one char
(passphrase.length + 1).times do |i|
  characters.chars.each do |c|
   testphrase = passphrase.dup
   testphrase.insert(i, c)
   list << testphrase
  end
end
return list.uniq
end
wallet = File.read(wallet_file)
seed_base64 = wallet.match(/'seed': '([^']+)'/).captures.first
$seed = Base64.decode64(seed_base64)
$cipher = OpenSSL::Cipher.new('aes-256-cbc')
$cipher.iv = $seed.slice!(0,16)
Dir.chdir File.dirname $protoshares
list1 = scramble(passphrase)
list1.each { |i| test i }
list1.each { |i| scramble(i).each { |j| test j }}
puts "No luck."
exit 1

4) EDIT brute.rb, filling in these values:
1. At the top; where the code says oops I forgot, edit this to be the password you believe should work for your wallet.
2. Inside the quotes after $wallet_file =, insert the full path to your wallet.dat file for protoshares-qt (e.g. C:\Protoshares\wallet.dat)
3. Inside the quotes after $protoshares, insert the full path to the protoshares-qt.exe file. (e.g. C:\Protoshares\protoshares-qt.exe)

5) Go to the start menu and choose run...

6) Type cmd and press enter

7) In the big black window that appears, type cd, followed by a space, and then the full path to the folder that proshares-qt.exe is in. E.g. cd C:\Protoshares\)

Cool

Type the following, then press enter.

Code:

protoshares-qt -server -rpcpassword=some-password -rpcport=3838

9) Finally, type brute.rb and wait.

Hi thanks for your help so far couple of things I wanted to check.

I edited the file at the start while it was still in txt format and then saved to "brute.rb" is this correct? I couldn't find a way to edit it once I'd saved it as "brute.rb"

The part in the CMD window where you type rpcpassword=some-password what do I need to type in here? do I have to create a .conf file in the same file as the wallet.dat?

On the last step, I've tried using windows CMD and the Ruby version at step 8 I press enter and the protoshares-qt opens when I then type brute.rb in the CMD window and press enter I get the following message

C:\"filepath"\brute.rb:62:in '

' : undefined method 'captures' for nil:NILClass

Old post and old thread, but I found this browsing the web. having same error. any idea?
