使用 C# CertAddCRLContextToStore 导入 CRL

问题描述

我正在尝试使用 C# 中的 Win32 api CertAddCRLContextToStore 将 crl 添加到我的证书存储中。下面的代码在尝试将 crl 内容解析为 CRL_CONTEXT 时不起作用并且失败。我们可以通过其他方式做到这一点吗？还是我的代码中遗漏了什么？

    private const int CERT_STORE_PROV_SYstem = 10;
    private const int CERT_SYstem_STORE_LOCAL_MACHINE = (2 << 16);

    public const int CERT_QUERY_OBJECT_FILE = 0x00000001;
    public const int CERT_QUERY_CONTENT_FLAG_PKCS7_SIGNED = 1 << 8;
    public const int CERT_QUERY_FORMAT_FLAG_BINARY = 1 << 1;
    public const int CERT_STORE_ADD_REPLACE_EXISTING = 1 << 3;

    [DllImport("CRYPT32.DLL",CharSet = CharSet.Auto,SetLastError = true)]
    public static extern IntPtr CertOpenStore(
      int storeProvider,int encodingType,IntPtr hcryptProv,int flags,string pvPara);

    [DllImport("CRYPT32.DLL",EntryPoint = "CryptQueryObject",SetLastError = true)]
    public static extern bool CryptQueryObject(
        int dwObjectType,[MarshalAs(UnmanagedType.LPWStr)] String pvObject,int dwExpectedContentTypeFlags,int dwExpectedFormatTypeFlags,int dwFlags,IntPtr pdwMsgAndCertEncodingType,IntPtr pdwContentType,IntPtr pdwFormatType,IntPtr phCertStore,IntPtr phMsg,ref IntPtr ppvContext);

    [DllImport("crypt32.dll",SetLastError = true)]
    private static extern bool CertAddCRLContextToStore(
      IntPtr hCertStore,IntPtr pCertContext,uint dwAdddisposition,IntPtr ppStoreContext);

    IntPtr hLocalCertStore = CertOpenStore(
              CERT_STORE_PROV_SYstem,IntPtr.Zero,CERT_SYstem_STORE_LOCAL_MACHINE,"CA");

    IntPtr pvContext = IntPtr.Zero;
    bool queryResult = CryptQueryObject(
            CERT_QUERY_OBJECT_FILE,@"sample.crl",CERT_QUERY_CONTENT_FLAG_PKCS7_SIGNED,CERT_QUERY_FORMAT_FLAG_BINARY,ref pvContext
        );

    // FAILS HERE 
    if (!queryResult)
    {
        throw new Exception("CryptQueryObject error #" + Marshal.GetLastWin32Error());
    }

    bool addResult = CertAddCRLContextToStore(
        hLocalCertStore,pvContext,CERT_STORE_ADD_REPLACE_EXISTING,IntPtr.Zero);

    if (!addResult)
    {
        throw new Exception("CryptQueryObject error #" + Marshal.GetLastWin32Error());
    }
