Poznámky

CspKeyContainerInfo Pomocí vlastnosti můžete načíst další informace o páru kryptografických klíčů. Vrácený CspKeyContainerInfo objekt popisuje, zda je klíč exportovatelný, a určuje název kontejneru klíčů, informace o zprostředkovateli a další informace.

V případech, kdy se vygeneruje náhodný klíč, se kontejner klíčů nevytvořil, dokud nezavoláte metodu, která tento klíč používá. Některé vlastnosti objektu CspKeyContainerInfo vrácené CspKeyContainerInfo vlastností vyvolá, CryptographicException pokud nebyl vytvořen kontejner klíčů. Před voláním CspKeyContainerInfo vlastnosti se ujistěte, že byl vytvořen kontejner klíčů, zavolejte metodu, například Encrypt, DecryptSignData, SignHash, atd.
