With VLC's Mozilla plugin, it's even very easy to view both streams in

For someone's summer project, MingW is now supported for the OpenSSL
installer at http://www.slproweb.com/products.html

socketW is a project in C++, but has a very simple SSL encrypted server
& client example (and works on Windows, Linux,et al)

http://www.digitalfanatics.org/cal/socketw/index.html

Server side example:


#include "SocketW.h"
...
SWSSLSocket listener;
SWSSLSocket *mySocket;

listener.use_cert("cert.pem", "cert_key.pem");  // Load certificate

listener.bind(5555);
listener.listen();

mySocket = (SWSSLSocket *)listener.accept();

// send encrypted message to client...
mySocket->sendmsg("Hello Client!");

// disconnect and clean up
mySocket->disconnect();
delete mySocket;


Client side example:


#include "SocketW.h"
...
SWSSLSocket mySocket;

mySocket.use_verification("cert.pem", NULL);  // Trust the certificates in
                                               // cert.pem
mySocket.connect(5555, "localhost");

// Check verification
SWSSLSocket::verify_info vinfo = mySocket.get_verify_result();
if( vinfo.result != SWSSLSocket::CertOk ){
     // We don't trust the server
     mySocket.disconnect();
     exit(-1);
}

// receive encrypted message from server...
string msg = mySocket.recvmsg();

// disconnect
mySocket.disconnect();
