Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

CspParameters.cs

Represents the key container name for CspParameters.

public: System::String ^ KeyContainerName;

public string? KeyContainerName;

val mutable KeyContainerName : string

Public KeyContainerName As String 

Field Value

String

Examples

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

using namespace System;
using namespace System::IO;
using namespace System::Security::Cryptography;
int main()
{
   
   // creates the CspParameters object and sets the key container name used to store the RSA key pair
   CspParameters^ cp = gcnew CspParameters;
   cp->KeyContainerName = "MyKeyContainerName";
   
   // instantiates the rsa instance accessing the key container MyKeyContainerName
   RSACryptoServiceProvider^ rsa = gcnew 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{0}", rsa->ToXmlString( true ) );
}

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));
    }
}

Public Class StoreKey
    
    Public Shared Sub Main()
        ' creates the CspParameters object and sets the key container name used to store the RSA key pair
        Dim cp As New CspParameters()
        cp.KeyContainerName = "MyKeyContainerName"
        
        ' instantiates the rsa instance accessing the key container MyKeyContainerName
        Dim rsa As 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 : "  & rsa.ToXmlString(True))
    End Sub
End Class

Remarks

Use the KeyContainerName field to specify a name for your key container. You can use the container name to retrieve the persisted key within that container.
