2021-11-29T04:20:02.913+00:00 Hi,
Thanks for your information.
Can i protect a file(like text file, ini file, etc..) through key storage provider?
if it is possible, how can i achieve it in C#.Net? -

2021-11-29T05:27:46.48+00:00 Yes. The file data is the equivalent of rgbPlaintext. Using CNG is the same as Calling Native Functions from Managed Code.

I don't understand about CNG and Key storage provider.
What is CNG? Why does it required?
What is different between CNG and Key storage provider?My requirement is :
i have a C#.Net console application which collects some important data from a configuration file (.ini file). I want to protect/secure this configuration file in Windows operating system by using key storage provider.
How can i achieve it? -

CNG is a set of APIs which provide a abstract model for private key storage.
Have a look at SignHash which calls NCryptOpenStorageProvider. As far as I see, StorageProvider provides some services. -
