Maybe this will help someone with mistyped password on Windows. This is a short Powershell script that tries the passwords read from standard input as rapidly as the particular cryptocoin client will allow.
You can either feed it a file/dictionary of possible passwords:
For someone who already has the Ruby installed on their Windows machine you can take those programs and delete the system() call and the case/end statement below it. Also change 'print phrase, "\t"' to 'puts phrase'. They should speed up the checks to the maximum achievable without hacking the wallet-handling code in the Satoshi client.
Code:
#
# Please put the correct username/password below
#
$h = new-object Net.WebClient
$h.Credentials = new-object Net.NetworkCredential("user","pass")
$h.Encoding = [Text.Encoding]::Default
#
# read the passord guesses from standard input
#
$Input | foreach {
try {
$p = $_ # + 'Kongreßstraße'
Write-Output "Trying '$p'"
$r = $h.UploadString('http://localhost:8332/','{"method":"walletpassphrase","params":["'+$p+'",1]}')
# Write-Output $r
#
# Correct password found!
#
break
}
catch [Net.WebException] {
$e = $_
switch -wildcard ($e.Exception.Message) {
"*(401) Unauthorized*" {
Write-Output "Fix the user/pass!"
Exit-PSSession
}
"*(500) Internal Server Error*" {
continue
}
default {
$e | Format-List -Force
Exit-PSSession
}
}
}
}
#
# Exiting without success!
#
Write-Output "Exiting!"
# Please put the correct username/password below
#
$h = new-object Net.WebClient
$h.Credentials = new-object Net.NetworkCredential("user","pass")
$h.Encoding = [Text.Encoding]::Default
#
# read the passord guesses from standard input
#
$Input | foreach {
try {
$p = $_ # + 'Kongreßstraße'
Write-Output "Trying '$p'"
$r = $h.UploadString('http://localhost:8332/','{"method":"walletpassphrase","params":["'+$p+'",1]}')
# Write-Output $r
#
# Correct password found!
#
break
}
catch [Net.WebException] {
$e = $_
switch -wildcard ($e.Exception.Message) {
"*(401) Unauthorized*" {
Write-Output "Fix the user/pass!"
Exit-PSSession
}
"*(500) Internal Server Error*" {
continue
}
default {
$e | Format-List -Force
Exit-PSSession
}
}
}
}
#
# Exiting without success!
#
Write-Output "Exiting!"
You can either feed it a file/dictionary of possible passwords:
Code:
powershell -executionpolicy bypass -file bitcrack.ps1 < dictionary.txt
or a pipe in the one-per-line output from the password generator:Code:
generator.exe | powershell -executionpolicy bypass -file bitcrack.ps1
.For someone who already has the Ruby installed on their Windows machine you can take those programs and delete the system() call and the case/end statement below it. Also change 'print phrase, "\t"' to 'puts phrase'. They should speed up the checks to the maximum achievable without hacking the wallet-handling code in the Satoshi client.
Thank you, 2112, this looks promising.
I have changed the brute.rb script from Revalin according to your suggestions and I am now using it as a password generator for your powershell script. It took some trying but now I know that there is something like a decent cli on windows
The whole thing runs very fast now. Problem is, I still do have the problems with the umlauts. Again I have checked that using a fresh, empty wallet with a password containing umlauts -which was not found. If I set the password to one without umlauts, your script finds it.
I assume that this has something to do with the encodings settings in your script. I already tried changing the encoding to 'BigEndianUnicode' and 'UTF8', but in both circumstances, the password was not found.
Do you have any further ideas.
Slightly less desperated, maybe even a bit optimistic ...
