获取证书KeyContainerName等属性

Question

我正在尝试使用自定义生成的证书签署 XML，该证书可通过此代码访问

private void buttonSelectCertificate_Click(object sender, EventArgs e)
{
   CertStoreLocation = (StoreLocation)cboStoreLocation.SelectedItem;
   CertStoreName = (StoreName)cboStoreName.SelectedItem;
   X509Store store = new X509Store(CertStoreName, CertStoreLocation);
            store.Open(OpenFlags.ReadOnly);
   X509Certificate2Collection scollection = X509Certificate2UI.SelectFromCollection(store.Certificates, "Certificate Select", "Select a certificate from the following list to get information on that certificate",  System.Security.Cryptography.X509Certificates.X509SelectionFlag.SingleSelection);
}

我不知道如何正确使用X509Certificate2Collection scollection 为了填写以下属性。

我也没有得到以下想法：

如果证书存储在这里 My = 5 那么我使用 CspProviderFlags.UseMachineKeyStore ？

如何从 X509Certificate2Collection scollection 获取 KeyContainerName？

最后，也许我获取填充 CspParameters class 所需的证书属性的方式完全错误，有什么线索吗？

感谢您的帮助！

// Get the key pair from the key store.
CspParameters parms = new CspParameters(1);         // PROV_RSA_FULL
parms.Flags = ??? CspProviderFlags.UseMachineKeyStore;  // Use Machine store
parms.KeyContainerName = ???;               // 
parms.KeyNumber = 2;                                // AT_SIGNATURE
RSACryptoServiceProvider csp = new RSACryptoServiceProvider(parms);

Answer 1

这里是答案

private void buttonSelectCertificate_Click(object sender, EventArgs e)
{
   CertStoreLocation = (StoreLocation)cboStoreLocation.SelectedItem;
   CertStoreName = (StoreName)cboStoreName.SelectedItem;
   X509Store store = new X509Store(CertStoreName, CertStoreLocation);
            store.Open(OpenFlags.ReadOnly);
   X509Certificate2Collection scollection = X509Certificate2UI.SelectFromCollection(store.Certificates, "Certificate Select", "Select a certificate from the following list to get information on that certificate",  System.Security.Cryptography.X509Certificates.X509SelectionFlag.SingleSelection);


  foreach (X509Certificate2 cert in scollection)
            {

                var rsa = cert.PrivateKey as RSACryptoServiceProvider;
                if (rsa == null) continue; // not smart card cert again

                if (!string.IsNullOrEmpty(rsa.CspKeyContainerInfo.KeyContainerName))
                {
                    // This is how we can get it! :)  
                    var keyContainerName = rsa.CspKeyContainerInfo.KeyContainerName;
                }
            }
}

而且我们也正常使用CspProviderFlags.UseMachineKeyStore

CspParameters parms = new CspParameters(1);         // PROV_RSA_FULL
parms.Flags = CspProviderFlags.UseMachineKeyStore;  // Use Machine store
