Creating a custom SSL client/server

So far, we have been dealing more with the SSL or TLS client. Now, let us have a look at the server side briefly. As you are already familiar with the TCP/UDP socket server creation process, let's skip that part and just concentrate on the SSL wrapping part. The following code snippet shows an example of a simple SSL server:

import socket
import ssl

SSL_SERVER_PORT = 8000

if __name__ == '__main__':
    server_socket = socket.socket()
    server_socket.bind(('', SSL_SERVER_PORT))
    server_socket.listen(5)
    print("Waiting for ssl client on port %s" %SSL_SERVER_PORT)
    newsocket, fromaddr = server_socket.accept()
    # Generate your server's  public certificate and private key pairs.
    ssl_conn = ssl.wrap_socket(newsocket, server_side=True, certfile="server.crt", keyfile="server.key", ssl_version=ssl.PROTOCOL_TLSv1)
    print(ssl_conn.read())
    ssl_conn.write('200 OK\r\n\r\n'.encode())
    print("Served ssl client. Exiting...")
    ssl_conn.close...
