Opmerkingen

Gebruik deze klasse om aanvullende informatie te verkrijgen over een sleutelpaar, zoals de naam van de sleutelcontainer of het sleutelnummer.

In gevallen waarin een willekeurige sleutel wordt gegenereerd door de RSACryptoServiceProvider of de DSACryptoServiceProvider, wordt er pas een sleutelcontainer gemaakt wanneer u een methode aanroept die gebruikmaakt van de sleutel. Sommige eigenschappen van de CspKeyContainerInfo klasse genereren een CryptographicException als er geen sleutelcontainer is gemaakt.
