Great tool!

I've played a bit with your code and here is my version:

Displays a message when there is no password needed to connect to a WLAN
Translates the NetSh output from OEM to ANSI to prevent problems with other languages (tested my version with German)
Moved the constants to variables for easier translation
Brushed up the code a bit

A very nice tool.
Maybe it would be possible to add a delete button for obsolete items.

Thanks water, I updated the program.

Edited June 23, 2022 by Hunter070

Exit · June 24, 2022

Here we have a Babylonian confusion of languages.
The Water solution only works with German locale.
The Hunter070 solution only works with English locale.

This is because the netsh output is parsed with locale constants.

e.g.
Global Const $sProfile = "All User Profile"
Global Const $sProfile = "Profil für alle Benutzer"

A language-independent version would be desirable.

water · June 24, 2022

I do not know of a way to change the language for CMD.

Another idea would be to run a command like "print /?" then examine the returned text to determine the language.
The needed text constants could then be read from an ini file.

What do you think?

Danp2 · June 24, 2022

What about using @OSLang?

funkey · June 24, 2022

All infos can be found in registry language independent. But I don't have a PC here with wifi adapter for testing.

This could be a registry key to start: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces

The Wifi passwords are stored under C:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces\[Interface Guid]. The encrypted keys are stored in .xml file.

Edit: I think this is far too complicated, so @OSLang is easiest way to go for now.

Edited June 24, 2022 by funkey

jguinch · June 24, 2022

Can you try this in command line (in elevated cmd):

md c:\Windows\Temp\wifi
cd /d c:\Windows\Temp\wifi
netsh wlan export profile key=clear

so you will have one xml file per SSID, in c:\windows\temp\wifi. You can now parse each XML file to get the informations you need. ~~Not sure it contains the key...~~

Edited June 24, 2022 by jguinch

Danp2 · June 24, 2022

@jguinchThe exported files contain the encrypted key. To export the unencrypted key, change the last line to this --

netsh wlan export profile key=clear

Exit · June 24, 2022

Simply read out the information regardless of the language.

Here is a hopefully language-independent solution:

#include <Array.au3>
#include <string.au3>
Global $hDLL = DllOpen("user32.dll")
$aSSIDs = _GetSSIDs()
For $i = 0 To UBound($aSSIDs) - 1
    $key = _GetKeyFromSSID($aSSIDs[$i])
    ConsoleWrite(@TAB & $aSSIDs[$i] & @TAB & @TAB & $key & @CRLF)
Next

Func _GetSSIDs()
    Local $iPID = Run(@ComSpec & " /c " & 'netsh wlan show profile', @ScriptDir, @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)
    ProcessWaitClose($iPID)
    Local $sOutput = StdoutRead($iPID)
    Local $aOutput = DllCall($hDLL, 'Int', 'OemToChar', 'str', $sOutput, 'str', '')
    $aOutput = _StringExplode($aOutput[2], "-" & @CRLF)
    $sOutput = $aOutput[UBound($aOutput) - 1]
    Local $aSSIDs = _StringBetween($sOutput, " : ", @CRLF)
    Return $aSSIDs
EndFunc   ;==>_GetSSIDs

Func _GetKeyFromSSID($sSSID) ;returns "1" if key is not present
    Local $iPID = Run(@ComSpec & " /c " & 'netsh wlan show profile name="' & $sSSID & '" key=clear', @ScriptDir, @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)
    ProcessWaitClose($iPID)
    Local $sOutput = StdoutRead($iPID)
    Local $aOutput = DllCall($hDLL, 'Int', 'OemToChar', 'str', $sOutput, 'str', '')
    $aOutput = _StringBetween($aOutput[2], " : ", @CRLF)
    Return $aOutput[UBound($aOutput) - 6]
EndFunc   ;==>_GetKeyFromSSID

Can the foreign language users please confirm that it works in their language.
German OK
English No
French ?
others ?

@ExitIn English, that doesn't correctly retrieve the passkey for me (they all displayed "Unrestricted"). I took a quick glance at the array contents, and I think a more complex method will be required to retrieve the correct array element.

Exit · June 24, 2022

since i only have access to the german version, i can't help.
But surely someone will pick up the thread and continue spinning it.

kurtykurtyboy · June 24, 2022

I really like this tool!

@Exit In English, I have a similar output "Unrestricted". For me, the offset is 7 instead of 6.

    $sOutput = $aOutput[UBound($aOutput) - 1]
    Local $aSSIDs = _StringBetween($sOutput, " : ", @CRLF)
    Return $aSSIDs
EndFunc   ;==>_GetSSIDs

    Local $iPID = Run(@ComSpec & " /c " & 'netsh wlan show profile name="' & $sSSID & '" key=clear', @ScriptDir, @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)

    $aOutput = _StringBetween($aOutput[3], " : ", @CRLF)

chcp changes the language of command prompt

@Hunter070That works for me (English). But I don't think changing the code page will change the language of the netsh output.. I tried changing it to Russian for fun and the output looked exactly the same.

Here is another roundabout solution. It exports the profile to an xml file then grabs the password and deletes the file. But this all depends on if other languages use the same file tags <keyMaterial> or some other translated string. Could someone test?

* I also changed the SSID grabber to use a regular expression since it seems more straightforward to me, but I know others don't like it, so 🤷‍♂️.

#include <AutoItConstants.au3>
#include <StringConstants.au3>
Global $hDLL = DllOpen("user32.dll")
$aSSIDs = _GetSSIDs()
For $i = 0 To UBound($aSSIDs) - 1
    $key = _GetKeyFromSSID($aSSIDs[$i])
    ConsoleWrite(@TAB & $aSSIDs[$i] & @TAB & @TAB & $key & @CRLF)
Next

Func _GetSSIDs()
    Local $iPID = Run(@ComSpec & " /c " & 'netsh wlan show profile', @ScriptDir, @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)
    ProcessWaitClose($iPID)
    Local $sOutput = StdoutRead($iPID)
    Local $aOutput = DllCall($hDLL, 'Int', 'OemToChar', 'str', $sOutput, 'str', '')
    Local $aSSIDs = StringRegExp($aOutput[2], '(?m)\s+:\s+(.*?)$', $STR_REGEXPARRAYGLOBALMATCH)
    Return $aSSIDs
EndFunc   ;==>_GetSSIDs

Func _GetKeyFromSSID($sSSID) ;returns "1" if key is not present

    ;export to xml file
    Local $iPID = Run(@ComSpec & " /c " & 'netsh wlan export profile name="' & $sSSID & '" folder="' & @ScriptDir & '" key=clear', @ScriptDir, @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)
    ProcessWaitClose($iPID)
    Local $sOutput = StdoutRead($iPID)
    Local $aOutput = DllCall($hDLL, 'Int', 'OemToChar', 'str', $sOutput, 'str', '')

    ;get filename of the file that was exported
    $aRegExp = StringRegExp($aOutput[2], '"((?:""|[^"])*)"', $STR_REGEXPARRAYGLOBALMATCH  )
    $sFilename = $aRegExp[1]

    ;load the file and parse out the password
    $sFileData = FileRead($sFilename)
    FileDelete($sFilename)
    $aPassword = StringRegExp($sFileData, '(?m)<keyMaterial>(.*?)</keyMaterial>', $STR_REGEXPARRAYGLOBALMATCH )

    ;if error, then no password was found
    If @error Then
        Return ""
    Else
        Return $aPassword[0]
    EndIf

EndFunc   ;==>_GetKeyFromSSID

edit: I just saw @jguinch had already made the suggestion to export and read the profiles... here I was thinking I had this genius idea!

@kurtykurtyboy's latest script works on Italian system, you get a password in binary format. To get the password in clear text, add #RequireAdmin at the beginning of the script
