Exemples

L’exemple de code suivant importe les informations clés créées à partir d’un RSAParameters objet dans un RSACryptoServiceProvider objet.

try
{
   //Create a new RSACryptoServiceProvider object. 
   RSACryptoServiceProvider^ RSA = gcnew RSACryptoServiceProvider;
   
   //Export the key information to an RSAParameters object.
   //Pass false to export the public key information or pass
   //true to export public and private key information.
   RSAParameters RSAParams = RSA->ExportParameters( false );
   
   //Create another RSACryptoServiceProvider object.
   RSACryptoServiceProvider^ RSA2 = gcnew RSACryptoServiceProvider;
   
   //Import the key information from the other 
   //RSACryptoServiceProvider object.  
   RSA2->ImportParameters( RSAParams );
}
catch ( CryptographicException^ e ) 
{
   //Catch this exception in case the encryption did
   //not succeed.
   Console::WriteLine( e->Message );
}

try
{
    //Create a new RSACryptoServiceProvider object. 
    using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())
    {
        //Export the key information to an RSAParameters object.
        //Pass false to export the public key information or pass
        //true to export public and private key information.
        RSAParameters RSAParams = RSA.ExportParameters(false);
