在powershell中设置IIS绑定证书时发出

certificate iis ssl powershell

Jez · 技术社区 · 6 年前

我正在编写一个powershell脚本,以查看我的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。这是为了让我可以为许多绑定更新证书,因为我们对许多站点使用同一个证书,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 = "â76 ae 0b 2e b9 f7 45 ce 27 c4 02 6e 90 66 62 93 69 d7 5e 4c"
$ReplacementCertThumbprint = "â7f 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,因为电话 .RebindSslCertificate(...) 给出以下powershell错误:

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

并不是最有用的错误,我也不明白为什么会这样。我看这些论点没问题;指纹是 Get-ChildItem 代码和“我的”看起来不错。我唯一能想到的是,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。有人能帮我解释一下为什么会发生这个错误吗?

原来我也有同样的问题 here ( RebindSslCertificate 证书与删除它然后调用 AddSslCertificate )当出于愚蠢的原因从windows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的ltr字符,因此我的指纹无效。我在脚本的开头添加了一个检查以防止:

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
}
