问密钥容器，足够安全，可以存储私钥？

EN

// Create the CspParameters object and set the key container 
// name used to store the RSA key pair.
CspParameters cp = new CspParameters();
cp.KeyContainerName = ContainerName;

// Create a new instance of RSACryptoServiceProvider that accesses
// the key container MyKeyContainerName.
RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cp);

// Display the key information to the console.
Console.WriteLine("Key retrieved from container : \n {0}", rsa.ToXmlString(true));
