Function Get-SqlServerKeys { <# .SYNOPSIS Gets SQL Server Product Keys from local and remote SQL Servers. Works with SQL Server 2005-2014 .DESCRIPTION Using a string of servers, a text file, or Central Management Server to provide a list of servers, this script will go to each server and get the product key for all installed instances. Clustered instances are supported as well. Requires regular user access to the SQL instances, SMO installed locally, Remote Registry enabled and acessible by the account running the script. Uses key decoder by Jakob Bindslet (http://goo.gl/1jiwcB) .PARAMETER Servers A comma separated list of servers. This can be the NetBIOS name, IP, or SQL instance name .PARAMETER CentralMgmtServer Compiles list of servers to inventory using all servers stored within a Central Management Server. Requires having SQL Management Studio installed. .PARAMETER ServersFromFile Uses a text file as input. The file must be formatted as such: sqlserver1 sqlserver2 .NOTES Author : Chrissy LeMaire Requires: PowerShell Version 3.0, SQL Server SMO, Remote Registry Version: 0.8.3 DateUpdated: 2015-June-2 .LINK https://gallery.technet.microsoft.com/scriptcenter/Get-SQL-Server-Product-4b5bf4f8 .EXAMPLE Get-SqlServerKeys winxp, sqlservera, sqlserver2014a, win2k8 Gets SQL Server versions, editions and product keys for all instances within each server or workstation. .EXAMPLE Get-SqlServerKeys -CentralMgmtServer sqlserver01 Gets SQL Server versions, editions and product keys for all instances within sqlserver01's Central Management Server .EXAMPLE Get-SqlServerKeys -ServersFromFile C:\Scripts\servers.txt Gets SQL Server versions, editions and product keys for all instances listed within C:\Scripts\servers.txt #> #Requires -Version 3.0 [CmdletBinding(DefaultParameterSetName="Default")] Param( [parameter(Position=0)] [string[]]$Servers, # Central Management Server [string]$CentralMgmtServer, # File with one server per line [string]$ServersFromFile ) BEGIN { Function Unlock-SQLServerKey { param( [Parameter(Mandatory = $true)] [byte[]]$data, [int]$version ) try { if ($version -ge 11) { $binArray = ($data)[0..66] } else { $binArray = ($data)[52..66] } $charsArray = "B","C","D","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","6","7","8","9" for ($i = 24; $i -ge 0; $i--) { $k = 0 for ($j = 14; $j -ge 0; $j--) { $k = $k * 256 -bxor $binArray[$j] $binArray[$j] = [math]::truncate($k / 24) $k = $k % 24 } $productKey = $charsArray[$k] + $productKey if (($i % 5 -eq 0) -and ($i -ne 0)) { $productKey = "-" + $productKey } } } catch { $productkey = "Cannot decode product key." } return $productKey } } PROCESS { if ((Get-Host).Version.Major -lt 3) { throw "PowerShell 3.0 and above required." } if ([Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") -eq $null ) { throw "Quitting: SMO Required.
