c# - 如何使用C#验证Powershell .ps1脚本的签名？

Question

我有一些签名的.ps1脚本，我需要验证它们是否已从C#项目正确签名，是否有任何算法或库可以执行此操作？

谢谢!

您可以托管PowerShell引擎以使用Get-AuthenticodeSignature cmdlet对此进行检查，例如:

using System.Collections.ObjectModel;
using System.Management.Automation;
using System.Management.Automation.Runspaces;

private bool VerifyPowerShellScriptSignature()
{
    using (var runspaceInvoke = new RunspaceInvoke())
    {
        string path = "C:\\Windows\\system32\\WindowsPowerShell\\v1.0\\" +
                      "Modules\\PSDiagnostics\\PSDiagnostics.psm1";
        Collection<PSObject> results =
            runspaceInvoke.Invoke("Get-AuthenticodeSignature " + path);
        Signature signature = results[0].BaseObject as Signature;
        return signature == null ? false : 
                                  (signature.Status == SignatureStatus.Valid);
    }
}
