Start it with no parameters to see usage. + +The server code was adapted from the Simple TLS Server on the OpenSSL Wiki. +The server code was modified to perform the echo function, and client code +was added to open a connection with the server and to send keyboard input +to the server. + +The new client code illustrates that: + +- Connection to the SSL server starts as a standard TCP 'connect'. +- Once connected with TCP, the client 'upgrades' to SSL using + SSL_connect(). +- When the SSL connection completes, data is sent and received using + SSL_write() and SSL_read(). +- Pretty simple. + +The cert.pem and key.pem files included are self signed certificates with the +"Common Name" of 'localhost'. + +Best to create the 'pem' files using an actual hostname. |
