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

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.

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!
