c# - Solution for writting a program for keep secret photos -

The solution to write a program to keep the secret photo.

I have many secret photos of me and my friends and I do not want anyone to see it, I just use Winrar and set the password feature and hide some encrypted and folder software Use the. But I think it's not safe enough.

As I am a C # programmer, I want to develop an application to do it.

• I want to know a solution for encrypt and decrypt file.
• Do I have to write an audience application? If I look through ACSSee or other programs, then I'm afraid it will cache my file.
• As I know that when we type "delete. (File)", then it is not the actual removal, no one can recover it. How can I ensure that my app will literally remove it (can I modify the data and it can not be used before removing it)?

FYI

• My PC is not connected to the internet and I bought it to keep it, I just do not want to do another thing to see my photos. .
• If my PC was broken I would not be sent to repair it for anyone.
• I'm the only one who uses it.

Update

My picture is only photos of shame, in fact I want to know how to do this and what I wrote It's just "believe"

like "I bought it, not wanting to do my second thing to see my photos"

It is so strange that if I 400 If you've spent dollars, do something like that. I will know though everyone is just joking it. Sorry to not clarify this question.

I just want to know how someone hacks in this situation. And how to save them from the C # language.
