将私钥写入令牌

如何解决将私钥写入令牌

我使用 PKCS#11 来模拟令牌，我在 Windows 证书存储中有一个证书，上面写着“您有一个与此证书对应的私钥”。我尝试找到可以读取证书私钥的 WinAPI 函数（该证书位于证书存储区或 pfx 格式的硬盘驱动器中）。我怎么能做到这一点？ 我的功能

static void ImportPrivateKey(const char* fileName,const char* password)
{
    HCERTSTORE  hSystemStore;

    //Open the certificate store to be searched
    if(hSystemStore = CertOpenStore(
      CERT_STORE_PROV_SYSTEM,NULL,CERT_SYSTEM_STORE_CURRENT_USER,L"MY"))
        printf("Opened the MY system store. \n");
    else
        printf( "Could not open the MY system store.\n");

    PCCERT_CONTEXT  pDesiredCert = NULL;
    LPWSTR lpszCertSubject = L"7172gka"; // !!!!  Name of certificate to search 

    // Search certificate
    if(pDesiredCert=CertFindCertificateInStore(
      hSystemStore,MY_ENCODING_TYPE,CERT_FIND_SUBJECT_STR,lpszCertSubject,pDesiredCert))
    {
        printf("The desired certificate was found. \n");
    }
    else
    {
        printf("Could not find the desired certificate.\n");
    }

    DWORD dwSize = 0;
    CRYPT_KEY_PROV_INFO* pKeyInfo = NULL;

    if(!(CertGetCertificateContextProperty( 
      pDesiredCert,CERT_KEY_PROV_INFO_PROP_ID,&dwSize))) 
    { 
        printf("Error getting key property.\n"); 
    }

    if(pKeyInfo) 
        free(pKeyInfo);

    pKeyInfo = (CRYPT_KEY_PROV_INFO*)malloc(dwSize);

    if(!pKeyInfo) 
    { 
        printf("Error allocating memory for pKeyInfo.\n"); 
    }

    if(!(CertGetCertificateContextProperty( 
      pDesiredCert,pKeyInfo,&dwSize)))
    {
        printf("The second call to the function failed\n");
    }

    printf("%s\n",pKeyInfo->pwszProvName);
    if(pKeyInfo->dwKeySpec == AT_SIGNATURE)
        printf("Ok!\n");
}
