在Powershell中设置IIS绑定证书时出现问题

我正在编写一个Powershell脚本，以浏览我的IIS绑定列表，找到任何具有特定“旧”证书指纹的证书，并用具有“新”指纹的证书替换它们的证书。这是因为我可以为许多绑定更新证书，因为我们在许多站点上使用相同的证书，所以我们需要将所有具有旧证书的绑定更新为新证书。下面是我的想法：

##### EDIT THESE VARIABLES #####
$SiteName = "movc-website-www"
$OldCertThumbprint = "‎76 ae 0b 2e b9 f7 45 ce 27 c4 02 6e 90 66 62 93 69 d7 5e 4c"
$ReplacementCertThumbprint = "‎7f fa 9f f3 90 b8 a2 d8 4c 98 51 47 a5 64 1d 90 f6 2f ca 73"

##### FUNCTIONS #####
Function ReplaceWebsiteBinding {
    Param(
        [string] $SiteName,
        [string] $OldCertThumbprint,
        [string] $ReplacementCertThumbprint
    );

    Import-Module WebAdministration;

    $ReplacedCount = 0

    $IISBindings = (Get-ItemProperty -Path "IIS:\Sites\$SiteName" -Name Bindings)
    for ($i=0; $i -lt ($IISBindings.Collection).Length; $i++) {
        if (($IISBindings.Collection[$i]).certificateHash -eq $OldCertThumbprint) {
            ($IISBindings.Collection[$i]).RebindSslCertificate($ReplacementCertThumbprint, "My")
            $ReplacedCount++
        }
    }

    Return $ReplacedCount
}

##### MAIN PROGRAM #####
$OldCertThumbprint = $OldCertThumbprint.Replace(" ", "").ToUpper()
$ReplacementCertThumbprint = $ReplacementCertThumbprint.Replace(" ", "").ToUpper()

# Check that cert with given thumbprints exist
$FoundCert = Get-ChildItem -Path Cert:\LocalMachine\My |
    Where-Object { $_.Thumbprint -eq $OldCertThumbprint } |
    Select-Object -ExpandProperty Thumbprint
if (!$FoundCert) {
    Write-Host "Old cert with thumbprint $OldCertThumbprint not found!"
    Exit
}

$FoundCert = Get-ChildItem -Path Cert:\LocalMachine\My |
    Where-Object { $_.Thumbprint -eq $ReplacementCertThumbprint } |
    Select-Object -ExpandProperty Thumbprint

if (!$FoundCert) {
    Write-Host "Replacement cert with thumbprint $ReplacementCertThumbprint not found!"
    Exit
}

# Associate new cert with bindings that have old cert
$ReplacedCount = ReplaceWebsiteBinding $SiteName $OldCertThumbprint $ReplacementCertThumbprint

Write-Host "Replaced $ReplacedCount binding(s)."

问题是，这不起作用，因为调用

.rebindslcertificate（…）

的行会给我以下Powershell错误：

Value does not fall within the expected range.
At (...)
+             ($IISBindings.Collection[$i]).RebindSslCertificate($Repla ...
+             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], ArgumentException
    + FullyQualifiedErrorId : System.ArgumentException

这并不是最有用的错误，我也不明白为什么我会得到它。在我看来，这些论点是正确的；指纹是由

Get ChildItem

代码找到的，“我的”看起来不错。我能想到的唯一一件事是，它可能在当前用户证书存储中查找，而不是在本地计算机证书存储中查找，这是所需证书所在的位置。有人能帮我解释为什么会发生此错误吗？

事实证明，我遇到的问题与所描述的相同（

重新绑定SLCertificate

证书与删除证书，然后调用

添加SLCertificate

）。由于某些愚蠢的原因从Windows中的证书对话框复制指纹时，它会在字符串的开头插入一个零宽度LTR字符，因此我的指纹无效。我在脚本的开头添加了一个对此的检查以防止：

if ($OldCertThumbprint -match "[\W-[\ ]]") {
    Write-Host "Old cert thumbprint contains non-word characters, maybe a zero-width LTR Unicode character at the beginning.  You almost certainly don't want this!  Aborting!"
    Exit
}
if ($ReplacementCertThumbprint -match "[\W-[\ ]]") {
    Write-Host "Replacement cert thumbprint contains non-word characters, maybe a zero-width LTR Unicode character at the beginning.  You almost certainly don't want this!  Aborting!"
    Exit
}

您的代码看起来是正确的。您是否以管理员身份运行？如果只运行以下代码，是否显示旧的和替换的指纹/主题？“$FoundCert=Get ChildItem-Path Cert:\LocalMachine\My”是，我以管理员身份运行。是的，将显示它们。要进一步验证防弹指纹，请使用“^[a-fA-F0-9]{40}$”。（假设sha1散列）
