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.
#!/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\)
8) Type the following, then press enter.
protoshares-qt -server -rpcpassword=some-password -rpcport=3838
9) Finally, type brute.rb and wait.
