Thanks.  I have actually looked at this library before.  It looks like it
might be able to do what I want, but my problem is that I don't really
understand how the protocol itself works very well.  I mean, from a high
level view, I thing something like this happens:

1) FTP client contacts server, sends command requesting secure connection.
2) Server responds by sending some sort of public key
3) Client uses key to encrypt the rest of the communication.

I don't really understand the nitty-gritty of what's going on, though.  I
can read the API for the library, but I am really lost as to how to use it.

I didn't see any docs on the site that clarify how it's supposed to be used. 
Did I miss something?  Is there somewhere else I should be looking?

Thanks
