在Win 7下更改带命名密钥容器的密码信息

在运行Windows7的某些系统上,我们在 当我们调用 CryptAcquireCertificatePrivateKey()我们得到一个错误 crypt_e_no_key_属性(0x8009200B)。

并非所有的盒子都会发生这种情况。我们自然而然地认为它是一个不在网络上的域机器的东西,在那里它不能刷新它的域内容,但是我们让它在一些独立的机器上复制。

我的钥匙代码

if((StoreHandle = CertOpenStore(CERT_STORE_PROV_SYSTEM, 0, 0, CERT_SYSTEM_STORE_CURRENT_USER, QWARQ_CERT_STORE_NAME)) != NULL)
     {
        /* Look for certificate with matching user guid.            */
        if((CertContext = CertFindCertificateInStore(StoreHandle,PKCS_7_ASN_ENCODING | X509_ASN_ENCODING, 0, CERT_FIND_SUBJECT_STR,DataBuffer, NULL)) != NULL)
        {
           if(CryptAcquireCertificatePrivateKey(CertContext, 0,NULL, &CryptProvHandle, &KeySpec, &FreeHandle))
           {
           }
           else
           {
                   DWORD dwError=GetLastError();   //CRYPT_E_NO_KEY_PROPERTY
           }
        }
     }

下面是生成密钥/密钥容器的代码

if(CryptAcquireContext(&hCryptProv,KEY_CONTAINER_NAME, NULL,PROV_RSA_FULL, 0) == FALSE) //CRYPT_NEWKEYSET
{
    DWORD result = GetLastError();
    if (NTE_BAD_KEY_STATE  == result)
    {
        DebugLogging::DbgPrintF(TEXT("[CertInitialization] NTE_BAD_KEY_STATE - user has changed his password \n"), result);
        return false;
    }
    else if (NTE_BAD_KEYSET != result)
    {
        DebugLogging::DbgPrintF(TEXT("[CertInitialization] could not acquire CSP[0x%x]\n"), result);
        return false;
    }

    if(CryptAcquireContext(&hCryptProv, KEY_CONTAINER_NAME, NULL,PROV_RSA_FULL, CRYPT_NEWKEYSET) == FALSE) //CRYPT_NEWKEYSET
    {
        DWORD result = GetLastError();
        DebugLogging::DbgPrintF(TEXT("[CertInitialization] could not acquire CSP from new keyset[0x%x]\n"), result);
        return false;
    }
}
if(CryptGenKey(hCryptProv, AT_KEYEXCHANGE, RSA2048BIT_KEY |CRYPT_EXPORTABLE, &hKey)== FALSE)
{
    DebugLogging::DbgPrintF(TEXT("CertGeneration() could not generate key[%d]\n"),GetLastError());
    return false;
}
