Definitie
Belangrijk
Bepaalde informatie heeft betrekking op een voorlopige productversie die aanzienlijk kan worden gewijzigd voordat deze wordt uitgebracht. Microsoft biedt geen enkele expliciete of impliciete garanties met betrekking tot de informatie die hier wordt verstrekt.
Hiermee haalt u het providertype van een sleutel op.

Het providertype. De standaardwaarde is 1.
Voorbeelden
In het volgende codevoorbeeld wordt een sleutelcontainer gemaakt en wordt informatie over die container opgehaald.

// container is created.
// Create some data to encrypt and display it.

Console.WriteLine("Data to encrypt: " + data);
// Convert the data to an array of bytes and

Console.WriteLine("Encrypted Data: " + Encoding.ASCII.GetString(encData));
Console.WriteLine();

Console.WriteLine();
// Create a new CspKeyContainerInfo object.

Opmerkingen
Geldige waarden worden bepaald door de cryptografische serviceprovider die wordt gebruikt om de sleutel te maken. Cryptografische serviceproviders zijn over het algemeen ingedeeld in groepen of families, die elk een eigen set gegevensindelingen en -processen hebben. Twee families die gebruikmaken van hetzelfde algoritme, zoals de RC2-blokcode, gebruiken vaak verschillende opvullingsschema's, verschillende sleutellengten en verschillende standaardmodi.
