validation可执行文件是否已签名（用于签署该exe的signtool）

在我的应用程序中，我需要validation它是否已签名。 如果签名继续执行并退出应用程序，如果没有。 signtool将用于签署应用程序。 有没有C＃代码可以做到这一点？

Answer 1

这是一个实用方法：

var signed = IsSigned(@"c:\windows\explorer.exe"); ... public static bool IsSigned(string filePath) { if (filePath == null) throw new ArgumentNullException(nameof(filePath)); var file = new WINTRUST_FILE_INFO(); file.cbStruct = Marshal.SizeOf(typeof(WINTRUST_FILE_INFO)); file.pcwszFilePath = filePath; var data = new WINTRUST_DATA(); data.cbStruct = Marshal.SizeOf(typeof(WINTRUST_DATA)); data.dwUIChoice = WTD_UI_NONE; data.dwUnionChoice = WTD_CHOICE_FILE; data.fdwRevocationChecks = WTD_REVOKE_NONE; data.pFile = Marshal.AllocHGlobal(file.cbStruct); Marshal.StructureToPtr(file, data.pFile, false); int hr; try { hr = WinVerifyTrust(INVALID_HANDLE_VALUE, WINTRUST_ACTION_GENERIC_VERIFY_V2, ref data); } finally { Marshal.FreeHGlobal(data.pFile); } return hr == 0; } [StructLayoutAttribute(LayoutKind.Sequential, CharSet = CharSet.Unicode)] private struct WINTRUST_FILE_INFO { public int cbStruct; public string pcwszFilePath; public IntPtr hFile; public IntPtr pgKnownSubject; } [StructLayoutAttribute(LayoutKind.Sequential)] private struct WINTRUST_DATA { public int cbStruct; public IntPtr pPolicyCallbackData; public IntPtr pSIPClientData; public int dwUIChoice; public int fdwRevocationChecks; public int dwUnionChoice; public IntPtr pFile; public int dwStateAction; public IntPtr hWVTStateData; public IntPtr pwszURLReference; public int dwProvFlags; public int dwUIContext; public IntPtr pSignatureSettings; } private const int WTD_UI_NONE = 2; private const int WTD_REVOKE_NONE = 0; private const int WTD_CHOICE_FILE = 1; private static readonly IntPtr INVALID_HANDLE_VALUE = new IntPtr(-1); private static readonly Guid WINTRUST_ACTION_GENERIC_VERIFY_V2 = new Guid("{00AAC56B-CD44-11d0-8CC2-00C04FC295EE}"); [DllImport("wintrust.dll")] private static extern int WinVerifyTrust(IntPtr hwnd, [MarshalAs(UnmanagedType.LPStruct)] Guid pgActionID, ref WINTRUST_DATA pWVTData); 

Answer 2

  private bool IsAssemblySigned() { var assembly = Assembly.GetAssembly(GetType()); var assemblyName = assembly.GetName(); var key = assemblyName.GetPublicKey(); return key.Length > 0; }

我建议你使用’CryptUIWizDigitalSign’API。 此链接可用作参考。
