Açıklamalar

sınıfı RsaProtectedConfigurationProvider , bir yapılandırma dosyasında depolanan hassas bilgileri şifrelemek için size bir yol sağlar ve bu da yetkisiz erişime karşı korunmasına yardımcı olur. Yerleşik örneği, sağlayıcıyı bildirerek ve Örnekler bölümünde gösterildiği gibi bu sınıfın bir örneğini oluşturmak yerine yapılandırma dosyasında uygun ayarları yaparak kullanırsınız RsaProtectedConfigurationProvider .

nesnesi, RsaProtectedConfigurationProvider yapılandırma bölümlerini şifrelemek ve şifresini çözmek için sınıf tarafından RSA sağlanan şifreleme işlevlerini kullanır.
