Comentarios
Use la CspKeyContainerInfo propiedad para recuperar información adicional sobre un par de claves criptográficas. El objeto devuelto CspKeyContainerInfo describe si la clave es exportable y especifica el nombre del contenedor de claves, la información sobre el proveedor y otra información.
En los casos en los que se genera una clave aleatoria, no se creará un contenedor de claves hasta que se llame a un método que use la clave. Algunas propiedades del CspKeyContainerInfo objeto devuelto por la CspKeyContainerInfo propiedad producirán un CryptographicException si no se ha creado un contenedor de claves. Para asegurarse de que se ha creado un contenedor de claves, llame a un método como Encrypt, Decrypt, SignData, SignHash, etc., antes de llamar a la CspKeyContainerInfo propiedad .
