Because in this case there is not an HTTP stack speaking over the port. 
It is not a "pull" or "poll", which yes of course an HTTPS request would 
provide. This is a bidirectional nearly raw TCP socket connection from 
the Browser via Flash, going over TCP to a server listening on some 
port. The server can of course take input over the socket, but there 
would not be any real gain in that over using some standard AJAX calls 
which would yes of course be able to take advantage of simple HTTPS. But 
to push data to the client (say, multiple streams of stock updates, 
logs, chat windows) without using any HTTP pull/poll request, the server 
has these nearly raw TCP sockets which end up firing Shock events on the 
browser.

See:
http://aflax.org/examples/sockets/sockets.html
http://www.heliant.net/~stsai/code/

So to perform this without pull/poll of the HTTP/S request cycle, I need 
to be able to encrypt and sign a message at the server and push the data 
along the TCP pipe to the browser, which has to be able to decrypt and 
verify the received data.
