找回已激活的SQL秘钥

    之前激活的秘钥已经忘记了，只能想办法从老机器上尝试找回秘钥。查了下用powershell会比较方便，也有现成的函数。

支持SQL Server 2008, 2008 R2

function Get-SQLServerKey {

## function to retrieve the license key of a SQL 2008 Server.

param ($targets = ".")

$hklm = 2147483650

$regPath = "SOFTWARE\Microsoft\Microsoft SQL Server\100\Tools\Setup"

$regValue1 = "DigitalProductId"

$regValue2 = "PatchLevel"

$regValue3 = "Edition"

Foreach ($target in $targets) {

$productKey = $null

$win32os = $null

$wmi = [WMIClass]"\\$target\root\default:stdRegProv"

$data = $wmi.GetBinaryValue($hklm,$regPath,$regValue1)

[string]$SQLver = $wmi.GetstringValue($hklm,$regPath,$regValue2).svalue

[string]$SQLedition = $wmi.GetstringValue($hklm,$regPath,$regValue3).svalue

$binArray = ($data.uValue)[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"

## decrypt base24 encoded binary data

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

}

}

$productKey = $charsArray[$k] + $productKey

If (($i % 5 -eq 0) -and ($i -ne 0)) {

$productKey = "-" + $productKey

}

}

$win32os = Get-WmiObject Win32_OperatingSystem -computer $target

$obj = New-Object Object
