Opening a SSL socket connection in Python

stackoverflow.com › questions › 26851034 › opening-a-ssl-socket-connection-in-python

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!

You shouldn't be setting PROTOCOL_TLSv1 (or TLSv1). This restricts the connection to TLS v1.0 only. Instead you want PROTOCOL_TLS (or the deprecated PROTOCOL_SSLv23) that supports all versions supported by the library.

You're using an anonymous cipher, because for some reason you think you don't need a certificate or key. This means that there is no authentication of the server and that you're vulnerable to a man in the middle attack. Unless you really know what you're doing, I suggest you don't use anonymous ciphers (like ADH-AES256-SHA).

ssl – SSL/TLS module — MicroPython latest documentation

Wrap the given sock and return a new wrapped-socket object. The implementation of this function is to first create an SSLContext and then call the SSLContext.wrap_socket method on that context object. The arguments sock, server_side and server_hostname are passed through unchanged to the method call.

To test for the presence of SSL support in a Python installation, user code should use the following idiom: try: import ssl except ImportError: pass else: [ do something that requires SSL support ] This example connects to an SSL server, prints the server’s address and certificate, sends some bytes, and reads part of the response: import socket, ssl, pprint s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # require a certificate from the server ssl_sock = ssl.wrap_socket(s, ca_certs="/etc/ca_certs_file", cert_reqs=ssl.CERT_REQUIRED) ssl_sock.connect(('www.verisign.com', 443)) print(repr(ssl_sock.getpeername())) pprint.pprint(ssl_sock.getpeercert()) print(pprint.pformat(ssl_sock.getpeercert())) # Set a simple HTTP request -- use http.client in actual code.

That’s the normal Python socket layer. You then create a default SSL context which has all the best practices of the installed Python version. You can furthermore drop some protocols if you feel like it and your requirements allow for that. Next you wrap the socket into an SSL socket.

August 3, 2007 - Basically you just wrap a standard socket with an SSL socket: import socket s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(('localhost', 12345)) sslSocket = socket.ssl(s) print repr(sslSocket.server()) print repr(sslSocket.issuer()) sslSocket.write('Hello secure socket\n') s.close() The server is a bit more tricky, you need to install pyopenssl (apt-get install python-pyopenssl) for more SSL features.
