Question

我尝试签名Xml文件。这是代码（来自MSDN）：

RSACryptoServiceProvider Key = new RSACryptoServiceProvider();
SignXmlFile(XmlStart, XmlEnd, Key);

如何以密钥形式发送X509Certificate2？坦克！弗朗西斯

Answer 1

在这里，您将使用证书中的密钥（公钥/私钥）。

选项1）

X509Certificate2 cert = RetrieveCertificate("abcd");
var key = cert.PrivateKey;

private static X509Certificate2 RetrieveCertificateFromStore(string certificateName)
{
    X509Store store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
    store.Open(OpenFlags.OpenExistingOnly);
    var cert = store.Certificates.OfType<X509Certificate2>().AsEnumerable().FirstOrDefault(c => c.FriendlyName == certificateName);
    return cert;
}

从文件中检索证书：

    private static X509Certificate2 RetrieveCertificateFromFile(string certPath)
    {
        // string certPath = @"C:\Certificates\myCert.pfx";
        string certPass = "mycertPass";
        // Create a collection object and populate it using the PFX file
        X509Certificate2Collection collection = new X509Certificate2Collection();
        collection.Import(certPath, certPass, X509KeyStorageFlags.PersistKeySet);
        // Instead of foreach you can directly retrieve the certificate from collection as well.
        foreach (X509Certificate2 cert in collection)
        {
            // Import the certificates into X509Store objects
            return cert;
        }
        return null;
    }

选项2）

RSACryptoServiceProvider key = RetrieveKey(cert, EnumKeyType.Private);

c＃使用X509Certificate2签名Xml
