If it's "urgent", why didn't you google for the solution?

I searched, but i'm not getting the appropriate information. Can you please suggest me a site?

FFS, what didn't you understand about "use google"?

If you google "c encryption example", you'll get almost 12 MILLION results back. Here's one of them:

If you're going to be a programmer, you'd better learn how to use the resources at hand to figure out how to do things.

Solution 2

I googled encrypt file C typed as three words separated by two spaces. There were about 2.9 million hits and the second one led me to this little gem on MSDN: http://msdn.microsoft.com/en-us/library/aa382358(v=vs.85).aspx[^].

Finding that was easy.
You couldn't find it.
I don't expect that the code sample will help you in any way.

Sorry!
