I'm trying to create a system where clients can encrypt messages, but
only the server can decrypt them. I'm configuring the context on the
server-side like so:

context_.set_options(boost::asio::ssl::context::default_workarounds
                                 | boost::asio::ssl::context::no_sslv2);
context_.set_password_callback(boost::bind(&server::get_password, this));
context_.use_private_key_file("server.pem", boost::asio::ssl::context::pem);

However, I can't find any way to load the public key on the clients.
Can I create a connection that relies on public-key encryption? Or do
the SSL classes expect me to use public-key encryption only to
generate symmetrical keys, ie with Diffie-Hellman?
