Hi, I have gone through the asio ssl client and server sample and modified. The modification I have done is, added one more certificate to the client by using "ctx.load_verify_file("another_cert.pem");" Now I have two server certificates loaded for server authentication. These are self signed certificate. But in client is there any way to know which server is authenticated? In real case we will be using this for client-authentication, to know what kind of client is connected to the server. We have two types of client, and one client has only restricted privileges. Thanks, Lloyd
