Opening a SSL socket connection in Python

Question

I'm trying to establish a secure socket connection in Python, and i'm having a hard time with the SSL bit of it. I've found some code examples of how to establish a connection with SSL, but they all involve key files. The server i'm trying to connect with doesn't need to receive any keys or certificates. My question is how do I essentially wrap a python socket connection with SSL. I know for a fact that the cipher i'm suppose to use is ADH-AES256-SHA, and the protocol is TLSv1. This is what i've been trying:

import socket import ssl  # SET VARIABLES packet, reply = "<packet>SOME_DATA</packet>", "" HOST, PORT = 'XX.XX.XX.XX', 4434  # CREATE SOCKET sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.settimeout(10)  # WRAP SOCKET ??? ssl.wrap_socket(sock, ssl_version="TLSv1", ciphers="ADH-AES256-SHA")  # CONNECT AND PRINT REPLY sock.connect((HOST, PORT)) sock.send(packet) print sock.recv(1280)  # CLOSE SOCKET CONNECTION sock.close() 

When I run this code, I don't get any errors, but I get a blank response. When trying to debug this code in the command line, by typing in python in the terminal and pasting in code line by line, I get what i'm assuming is a status code when running sock.send(packet). The integer response I get is 26. If anyone knows what this means, or can help in anyway it would be greatly appreciated. Thanks in advance!

Answer 1

Ok, I figured out what was wrong. It was kind of foolish of me. I had two problems with my code. My first mistake was when specifying the ssl_version I put in TLSv1 when it should have been ssl.PROTOCOL_TLSv1. The second mistake was that I wasn't referencing the wrapped socket, instead I was calling the original socket that I have created. The below code seemed to work for me.

import socket import ssl  # SET VARIABLES packet, reply = "<packet>SOME_DATA</packet>", "" HOST, PORT = 'XX.XX.XX.XX', 4434  # CREATE SOCKET sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.settimeout(10)  # WRAP SOCKET wrappedSocket = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_TLSv1, ciphers="ADH-AES256-SHA")  # CONNECT AND PRINT REPLY wrappedSocket.connect((HOST, PORT)) wrappedSocket.send(packet) print wrappedSocket.recv(1280)  # CLOSE SOCKET CONNECTION wrappedSocket.close() 

Hope this can help somebody!
