Beispiele

Im folgenden Codebeispiel werden Schlüsselinformationen importiert, die aus einem- RSAParameters Objekt in ein-Objekt erstellt wurden RSACryptoServiceProvider .The following code example imports key information created from an RSAParameters object into an RSACryptoServiceProvider object.

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);

        //Create another RSACryptoServiceProvider object.
        using (RSACryptoServiceProvider RSA2 = new 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 RSA As 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.
        Dim RSAParams As RSAParameters = RSA.ExportParameters(False)

        'Create another RSACryptoServiceProvider object.
        Using RSA2 As New RSACryptoServiceProvider()

            'RSACryptoServiceProvider object.  
            RSA2.ImportParameters(RSAParams)
        End Using
    End Using

Catch e As CryptographicException

    'not succeed.
