Comentarios

Use esta clase para obtener información adicional sobre un par de claves, como el nombre del contenedor de claves o el número de clave.

En los casos en los que o genera una clave RSACryptoServiceProviderDSACryptoServiceProvideraleatoria, no se creará un contenedor de claves hasta que llame a un método que use la clave. Algunas propiedades de la CspKeyContainerInfo clase producirán un CryptographicException si no se ha creado un contenedor de claves.
