Ejemplos
En el ejemplo de código siguiente se crea un contenedor de claves y se recupera información sobre ese contenedor.
using namespace System;
using namespace System::Security::Cryptography;
using namespace System::Text;
int main()
{
RSACryptoServiceProvider^ rsa = gcnew RSACryptoServiceProvider;
try
{
// Note: In cases where a random key is generated,
// a key container is not created until you call
// a method that uses the key. This example calls
// the Encrypt method before calling the
// CspKeyContainerInfo property so that a key
// container is created.
// Create some data to encrypt and display it.
String^ data = L"Here is some data to encrypt.";
Console::WriteLine( L"Data to encrypt: {0}", data );
// Convert the data to an array of bytes and
// encrypt it.
array<Byte>^byteData = Encoding::ASCII->GetBytes( data );
array<Byte>^encData = rsa->Encrypt( byteData, false );
// Display the encrypted value.
Console::WriteLine( L"Encrypted Data: {0}", Encoding::ASCII->GetString( encData ) );
Console::WriteLine();
Console::WriteLine( L"CspKeyContainerInfo information:" );

Comentarios
Los valores válidos los determina el proveedor de servicios criptográficos que se usa para crear la clave. Los proveedores de servicios criptográficos generalmente se organizan en grupos o familias, cada uno de los cuales tiene su propio conjunto de formatos y procesos de datos. Dos familias que usan el mismo algoritmo, como el cifrado de bloques RC2, a menudo usan esquemas de relleno diferentes, longitudes de clave diferentes y modos predeterminados diferentes.
