CspParameters Constructor

CspParameters Constructor

Initializes a new instance of the CspParameters class.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public CspParameters()

This form of CspParameters initializes the ProviderType field to a value of 24, which specifies the PROV_RSA_AES provider. This default provider is compatible with the Aes algorithm.

For information about other provider types, see the ProviderType field.

The following code example creates a key container using the CspParameters class and saves the key in the container.

using System;
using System.IO;
using System.Security.Cryptography;

public class StoreKey
{
	public static void Main()
	{
		// creates the CspParameters object and sets the key container name used to store the RSA key pair
		CspParameters cp = new CspParameters();
		cp.KeyContainerName = "MyKeyContainerName";

		// instantiates the rsa instance accessing the key container MyKeyContainerName
		RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cp);
		// add the below line to delete the key entry in MyKeyContainerName 
		// rsa.PersistKeyInCsp = false; 

		//writes out the current key pair used in the rsa instance
		Console.WriteLine("Key is : \n" + rsa.ToXmlString(true));
	}
}
