Beispiel

Im folgenden Codebeispiel werden die von einem RSAParameters-Objekt erstellten Schlüsselinformationen in ein RSACryptoServiceProvider-Objekt importiert.

Try
    'Create a new RSACryptoServiceProvider object. 
    Dim 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.
    Dim RSA2 As New RSACryptoServiceProvider()

    'Import the the key information from the other 
    'RSACryptoServiceProvider object.  
    RSA2.ImportParameters(RSAParams)


Catch e As CryptographicException
    'Catch this exception in case the encryption did
    'not succeed.
    Console.WriteLine(e.Message)
End Try

try
{
    //Create a new RSACryptoServiceProvider object. 
    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.
    RSACryptoServiceProvider RSA2 = new RSACryptoServiceProvider();

    //Import the 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. 
   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 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 );
}

    // 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 = new RSACryptoServiceProvider();

    // Import the 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.get_Message());
}
