Hi Team,
I want to protect my application configuration file through Microsoft Key Storage Provider (Cryptography API: Next Generation (CNG)) mechanism.
How to use Microsoft Key Storage Provider in Windows 2010 and Windows Server 2016 Operating Systems?
Could you please help me on this?
I have gone through the below link which is supports only in Windows Server 2008 and Windows Vista.

It seems Windows Server 2008 and Windows Vista is the Minimum supported server and client. And for using CNG, please refer to the segment.
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?
Yes. The file data is the equivalent of rgbPlaintext. Using CNG is the same as Calling Native Functions from Managed Code.
Or you can SignHash the file and then VerifySignature .
Thanks for your response.
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?
What is CNG?
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.
Thanks for your response.
Could you please share C# Code of SignHash the file and then VerifySignature.?
Your link code implemented in C++ language.
Have given in newest posted question.
I think you have given key storage functions code related. Please share SignHash the file and then VerifySignature code in C#
