[boost] Can boost ASIO SSL run one way SSL?

Hi, There is an example for running boost::asio::ssl for boost::asio::ip::tcp connection, it uses 2 way SSL which client uses the key and certificates to have two way SSL handshake. My boss asked me if it can be used for one way SSL similar to HTTPS, I don't think so, but I could be wrong. Appreciate your advice. Thank you. Kind regards, jupiter
