how to Find the password of all wlan via netsh

I want to find out the name of all my wlan along with their password:

ssid : password

With the search I made, I realized that it is possible to extract passwords individually with netsh But I need a batch script to get the name of each wlan, and extract and display the password for each name For example, I want the output to be like this:

ModemN1 :  123987654af
IsntModem : PASSw0rd!23

If you have another solution besides netsh, please tell me

can find all wlan profile:

C:> netsh wlan show profile

Profiles on interface Wi-Fi:

Group policy profiles (read only)
---------------------------------
    <None>

User profiles
-------------
    All User Profile     : ModemN1
    All User Profile     : IsntModem

It should extract two ModemN1, IsntModem strings here And for each of these strings, put the strings in this command: netsh wlan show profile <WLAN_NAME> key=clear

C:> netsh wlan show profile IsntModem key=clear

Profile IsntModem on interface Wi-Fi:
=======================================================================

Applied: All User Profile

Solution

  • I'm sure this has been parsed before though couldn't find a duplicate for it, you can give this a try, seems to work fairly well:

    netsh wlan show profile |
    Select-String '(?<=All User Profile\s+:\s).+' |
    ForEach-Object {
        $wlan = $_.Matches.Value
        $passw = netsh wlan show profile $wlan key=clear |
            Select-String '(?<=Key Content\s+:\s).+'

        [pscustomobject]@{
            Name     = $wlan
            Password = $passw.Matches.Value
        }
    }
