C# X509Certificate2对安全令牌中私钥的访问

我必须使用存储在安全令牌中的证书。我可以从windows证书存储访问它，但该设备有密码，因此会显示一个带有输入字段的弹出窗口

这是我用于加载证书的代码：

static X509Certificate2 BuscarCertificado
    (StoreLocation location, StoreName name, 
    X509FindType findType, string findValue)
{
    X509Store store = new X509Store(name, location);
    try{
        store.Open(OpenFlags.ReadOnly);

        X509Certificate2Collection col = store.Certificates.Find
            (findType, findValue, true);

        return col[0];
    }
    finally { store.Close(); }
}

该设备是ACS加密设备64 0

是否可以在不显示此消息的代码中发送密码

谢谢您的帮助

我没有ACS加密软件64 0。但此代码适用于西门子CardOS v4.3B驱动程序CardOS API v5.2 build 15。你必须检查一下它是否也适合你

不，这是不可能的。@这是一个有趣的理论，但你能证明它吗？请忽略我的评论。Pepo的代码应该适合您。不过，它需要将PIN码存储在代码中的某个位置不推荐不，这是不可能的。@CryptoGuy这是一个有趣的理论，但你能证明它吗？请忽略我的评论。Pepo的代码应该适合您。不过，它需要将PIN码存储在代码中的某个位置。不推荐您的代码不适用于我的eToken Pro。它抛出一个exception:exception调用Main，其中包含1个参数：证书的公钥与指定的值不匹配。在此行：certForSigning.PrivateKey=rsaCsp；eToken Pro是否有CSP或微型驱动程序？西门子5.2有一个微型驱动器。但西门子CardOS API v3.2有一个CSP。我必须添加它才能使其工作cspParameters.KeyNumber=privateKey.CspKeyContainerInfo.KeyNumber；cspParameters.Flags=CspProviderFlags.UseExistingKey；cspParameters初始化后。eToken使用CSP，而不是minidriver。如果在cspParameters中设置KeyNumber和标志，它是否工作？我只有西门子卡多斯……我很高兴。但是，只有当它是CSP时，才应该设置附加属性。使用minidriver时，它会突然停止工作。您的代码对我的eToken Pro不起作用。它抛出一个exception:exception调用Main，其中包含1个参数：证书的公钥与指定的值不匹配。在此行：certForSigning.PrivateKey=rsaCsp；eToken Pro是否有CSP或微型驱动程序？西门子5.2有一个微型驱动器。但西门子CardOS API v3.2有一个CSP。我必须添加它才能使其工作cspParameters.KeyNumber=privateKey.CspKeyContainerInfo.KeyNumber；cspParameters.Flags=CspProviderFlags.UseExistingKey；cspParameters初始化后。eToken使用CSP，而不是minidriver。如果在cspParameters中设置KeyNumber和标志，它是否工作？我只有西门子卡多斯……我很高兴。但是，只有当它是CSP时，才应该设置附加属性。有了minidriver，它就会突然停止工作。
