I've actually been intending to add the client side code to that package, but I simply haven't gotten around to it yet. It's actually not that complicated, but it does require some thought on the right interface for things like approving/rejecting server side certificates. If you open up an issue on Github for this, I'd be happy to continue the conversation there and we can try to get out a new version of the library. (I just don't want to spam the Cafe with an exploratory design discussion.)
