In this post, we will see how to view all the wireless profiles and WiFi passwords which are saved in the computer.

When a computer is connected to a wireless network, a profile is created with all the wireless network parameters and password. This details can be viewed in command prompt by looking into “netsh”

netsh command to view the profile names

C:\Users\MyPC>netsh wlan show profiles
***output***

Profiles on interface Wi-Fi:
Group policy profiles (read only)
---------------------------------
    <None>
User profiles
-------------
    All User Profile : mywifi 
    All User Profile : mywifi2

netsh command to view profile details

C:\Users\MyPC>netsh wlan show profiles name="mywifi" key=clear
***output***

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

Applied: All User Profile

To view the profile password, we have to issue the command seperately and the output is in plain text.

Below PowerShell script generate full details of all wireless profiles in the computer

function Get-WirelessProfilePassword
{
    $ProfileNames = @()
    $profilePropList = @()
    
    #Get all the wlan profiles
    $wLAN_Profiles = & netsh wlan show profiles

    #Extract the profile names to the list
    $wLAN_Profiles | % {$ProfileNames += if($_.split(":")[1]){($_.split(":")[1]).trim()}}

    #looping through the profile names to get the profile parameters
    foreach($profileName in $ProfileNames){
        #generating the command for profile parameter
        $command = '& netsh wlan show profiles name="' + $profileName + '" key=clear'
        #invoking the command
        $profileProp = Invoke-Expression $command

        #looping though the result and processing the text to list of PSCustom object class
        foreach($prop in $profileProp) {
            if(!($prop.split("+:")[1]) -and ($prop.split("+:")[0] -notmatch "----")){
                $type = $prop.split("+:")[0]
            }
            if(!($prop.split("+:")[0] -match "----") -and ($prop.split("+:")[0] -ne $type)){ 
                $PropItem = New-Object PSObject -Property @{
                    Profile = $profileName
                    Type = $type.trim()
                    Category = $prop.split("+:")[0].trim()
                    Property = $prop.split("+:")[1]
                }
                $profilePropList+=$PropItem
            }
        }
    }
    $profilePropList 
}

#Calling the function
Get-WirelessProfilePassword | where {$_.Category -eq "Key Content" -or $_.Property -eq "SSID Name"} | select Profile, Category, Property

Result:

Profile  Category    Property  
-------  --------    --------  
mywifi   Key Content  098745632145
mywifi2  Key Content  easypassword

The result is a list of PSObjects which is easy to sort, filter and to pass on to other powershell codes.
