hi dear;
Thanks for tutorial in http://www.radicalrabbit.de. It was very helpful to me. I have question if I want to encrypt each frame of video streaming at each time how can I get it?

Hi Ben,

take a look at the SSL version of the MJPEG server Python script:

https://github.com/radicalrabbit/PyMjpegServer/blob/master/src/sslMjpegStreamServer.py

To wrap SSL encryption around the socket the following code block is used:

    server.socket = ssl.wrap_socket(server.socket,
                                    certfile=os.path.join(dir, 'newcert.pem'),
                                    keyfile=os.path.join(dir, 'newkey_nopass.pem'),
                                    server_side=True,
                                    ca_certs=os.path.join(dir, 'cacert.pem'),
                                    cert_reqs=ssl.CERT_REQUIRED,
                                    ssl_version=ssl.PROTOCOL_TLSv1)

For the MJPEG stream I use mutual encryption between server and client(s). You will need a CA certificate, a server certificate and a client certifiacte to make it run. Have a look at the according Wiki article in my blog. The following post explains how to create the required SSL/TLS certificates on a Linux system (e.g. Raspbian):

Follow the tutorial and you will get mutual SSL encryption for every package / frame sent by the MJPEG server.

Cheers
