[Boost-users] Asio SSL verify peer

Hi, Checking asio::ssl sample, the client side code contains a way to verify the server certificate as ctx.set_verify_mode(boost::asio::ssl::context::verify_peer); ctx.load_verify_file("ca.pem"); What parameters are checked by this function? Is it possible to check the parameters in certificate file manually? (I have gone through openssl manual, it seems openssl has functions for that) And also how can I do a client authentication using SSL? Thanks a lot, Lloyd
