question about an application

Hello,

So I want to make an application ( in C#) that will protect folders with passwords, denying access if the one who attempts to open it, does not have the right password.

Initially I wanted to learn what System.Security.Cryptography does and what can be accomplished with using it, so I thought about doing this project. But someone told me that my idea with the folder protect cannot be done with any class from the .NET framework because I need something far more low level, etc.

Can you tell me a few tips on how would I start such an application, and if Cryptography class would have anything to do with it? I just want to use this class,to learn it.

Thanks.

You can learn that class from MSDN, and I'm sure there are many examples on Google to help with that class. But if you are just trying to learn how to use the Cryptography class, building a program that embeds itself into the operation system is completely the wrong direction. I would have no idea how to do it, but your program would have to be at a very low level in the operation system. It would be similar to writing a firewall or antivirus program.

This type of security is already done by Windows, its controled via user accounts in computer management, or the control panel, depending on which version you are using.

I would recommend you use C++ for this type of program, but it seems like you are only wanting to learn the Cryptopraphy class, not C++ and low-level design. You can type "System.Security.Cryptography" into Google or MSDN. I'm sure you will get hundreds of examples. I've been programming for 11 years, and this type of low-level code is over my head, and I have no intrest in learning it.
