Understanding SSL-Enabled REN Servers

You can enable a secure channel of communication between the clients and the REN server by enabling SSL on the REN server using openssl. The SSL protocol runs above Transmission Control Protocol/Internet Protocol (TCP/IP) and below higher-level protocols, such as HTTP and IMAP4. By using TCP/IP on behalf of higher-level protocols, openssl allows an SSL-enabled server to authenticate itself to an SSL-enabled client, a client to authenticate itself to a server, and both machines to establish an encrypted connection.
