You might be able to find third-party code for this, but no, there's nothing inside Flex or Flash to do this.
Have you considered setting up an SSL web server on the box instead, then sending the files up with HTTP POST? That you could do with Flex, with no special help. If you're wary of using HTTP due to bad experiences uploading files with a web browser, keep in mind that unlike with a browser, in Flash/Flex uploads are asynchronous -- the upload doesn't block your program -- and you can get progress update events.
