Question

证书已安装在计算机上。现在我想给应用程序用户提供有关证书PrivateKey的读取权限。

Answer 1

这是答案。

创建了一个powershell脚本文件AddUserToCertificate.ps1

以下是脚本文件的内容。

param(
    [string]$userName,
    [string]$permission,
    [string]$certStoreLocation,
    [string]$certThumbprint
);
# check if certificate is already installed
$certificateInstalled = Get-ChildItem cert:$certStoreLocation | Where thumbprint -eq $certThumbprint

# download & install only if certificate is not already installed on machine
if ($certificateInstalled -eq $null)
{
    $message="Certificate with thumbprint:"+$certThumbprint+" does not exist at "+$certStoreLocation
    Write-Host $message -ForegroundColor Red
    exit 1;
}else
{
    try
    {
        $rule = new-object security.accesscontrol.filesystemaccessrule $userName, $permission, allow
        $root = "c:\programdata\microsoft\crypto\rsa\machinekeys"
        $l = ls Cert:$certStoreLocation
        $l = $l |? {$_.thumbprint -like $certThumbprint}
        $l |%{
            $keyname = $_.privatekey.cspkeycontainerinfo.uniquekeycontainername
            $p = [io.path]::combine($root, $keyname)
            if ([io.file]::exists($p))
            {
                $acl = get-acl -path $p
                $acl.addaccessrule($rule)
                echo $p
                set-acl $p $acl
            }
        }
    }
    catch 
    {
        Write-Host "Caught an exception:" -ForegroundColor Red
        Write-Host "$($_.Exception)" -ForegroundColor Red
        exit 1;
    }    
}

exit $LASTEXITCODE

现在将其作为部署的一部分运行。在powershell控制台窗口中运行上面脚本的示例。

C:\>.\AddUserToCertificate.ps1 -userName testuser1 -permission read -certStoreLocation \LocalMachine\My -certThumbprint 1fb7603985a8a11d3e85abee194697e9784a253

此示例为 \ LocalMachine \ My 中安装的证书上的用户 testuser1 授予读取权限，并且有拇指指纹 1fb7603985a8a11d3e85abee194697e9784a253

如果您使用的是ApplicationPoolIdentity，那么您的用户名将是'IIS AppPool \ AppPoolNameHere'

注意：您需要使用''，因为IIS和AppPool之间有空格。

Answer 2

上面的答案对我不起作用，因为$_.privatekey返回null。我设法访问了私钥并为我的应用程序池分配了“读取”权限，如下所示：

param (
[string]$certStorePath  = "Cert:\LocalMachine\My",
[string]$AppPoolName,
[string]$certThumbprint
)

Import-Module WebAdministration

$certificate = Get-ChildItem $certStorePath | Where thumbprint -eq $certThumbprint

if ($certificate -eq $null)
{
    $message="Certificate with thumbprint:"+$certThumbprint+" does not exist at "+$certStorePath
    Write-Host $message -ForegroundColor Red
    exit 1;
}else
{
    $rsaCert = [System.Security.Cryptography.X509Certificates.RSACertificateExtensions]::GetRSAPrivateKey($certificate)
    $fileName = $rsaCert.key.UniqueName
    $path = "$env:ALLUSERSPROFILE\Microsoft\Crypto\Keys\$fileName"
    $permissions = Get-Acl -Path $path

    $access_rule = New-Object System.Security.AccessControl.FileSystemAccessRule("IIS AppPool\$AppPoolName", 'Read', 'None', 'None', 'Allow')
    $permissions.AddAccessRule($access_rule)
    Set-Acl -Path $path -AclObject $permissions
}

Answer 3

作为上述脚本的替代。您可以使用PowerShell模块。我自己没试过，但模块看起来不错。 http://get-carbon.org/index.html

这是设置权限的命令 http://get-carbon.org/Grant-Permission.html

Answer 4

您可以使用WinHttpCertCfg.exe，一个证书配置工具链接：https://docs.microsoft.com/en-us/windows/desktop/winhttp/winhttpcertcfg-exe--a-certificate-configuration-tool

一些代码示例：

Set privatekeyAcces to Svc-LocalAgent$@mydomain.local
*.\WinHttpCertCfg.exe -g -c LOCAL_MACHINE\MY -s *.d365.mydomain.com  -a "Svc-LocalAgent$@mydomain.com"*

Answer 5

添加迈克尔·阿米蒂奇（Michael Armitage）脚本，这对于存在私钥值和为空的情况都适用

function setCertificatePermission {
    param($accountName, $certificate)
    if([string]::IsNullOrEmpty($certificate.PrivateKey))
    {
        $rsaCert = [System.Security.Cryptography.X509Certificates.RSACertificateExtensions]::GetRSAPrivateKey($certificate)
        $fileName = $rsaCert.key.UniqueName
        $path = "$env:ALLUSERSPROFILE\Microsoft\Crypto\Keys\$fileName"
        $permissions = Get-Acl -Path $path
        $access_rule = New-Object System.Security.AccessControl.FileSystemAccessRule($accountName, 'FullControl', 'None', 'None', 'Allow')
        $permissions.AddAccessRule($access_rule)
        Set-Acl -Path $path -AclObject $permissions
    } else{
            $user = New-Object System.Security.Principal.NTAccount($accountName)
            $accessRule = New-Object System.Security.AccessControl.CryptoKeyAccessRule($user, 'FullControl', 'Allow')
            $store = New-Object System.Security.Cryptography.X509Certificates.X509Store("My","LocalMachine")
            $store.Open("ReadWrite")
            $rwCert = $store.Certificates | where {$_.Thumbprint -eq $certificate.Thumbprint}
            $csp = New-Object System.Security.Cryptography.CspParameters($rwCert.PrivateKey.CspKeyContainerInfo.ProviderType, $rwCert.PrivateKey.CspKeyContainerInfo.ProviderName, $rwCert.PrivateKey.CspKeyContainerInfo.KeyContainerName)
            $csp.Flags = "UseExistingKey","UseMachineKeyStore"
            $csp.CryptoKeySecurity = $rwCert.PrivateKey.CspKeyContainerInfo.CryptoKeySecurity
            $csp.KeyNumber = $rwCert.PrivateKey.CspKeyContainerInfo.KeyNumber
            $csp.CryptoKeySecurity.AddAccessRule($AccessRule)
            $rsa2 = New-Object System.Security.Cryptography.RSACryptoServiceProvider($csp)
            $store.close()
        }
}
