Ready to user sftp c++ library

I need a ready to use c++ library for transfering files via sftp in a windows MFC application.  I implement ftp functions in my application using the MFC CFtpConnection class, but need to add secure ftp.  The one I have found so far is Chilkat.  It looks good, but I wasn't able to find any info on whether it has a lot of overhead or is kind of messy.  Anyone have any experience with it?  Anyone know of another library that might be better?  Obviously, it would be nice if there was a free one available.

Filezilla is an open source ftp client and server - not a library.

You might want to look at how they implement the protocol in their code as an academic exercise,  see if the techniques they use are replicable in your own code. It could even be a straight copy if you don't have issues licensing your code with the GPL.

I'm afraid GPL won't work in my case.

I decided to use libcurl, which has a license agreement I can work with.
