Hello everyone,
First, I wanted to thank everyone in advance for your help and any feedback
is appreciated. Here is what I am trying to accomplish:
I have this encrypted data that was sent across the network. The decryption
is a simple XOR with a 16 byte key. I started writing a basic Python

You need to be very careful in your terminology here.
Is it a string of hex values ie a string representation of a hex
value or is it a
I just reinstalled Python v2.6.2 due to a computer crash. I reinstalled
IDLE v2.6 but I was wondering if there is something better than IDLE.
I am using Ubuntu 9.04 so they do have some limited choices available.
Thanks for your input.

Take the 4 byte XOR key. If I convert them to int with Base 16
it takes the 4 and converts it to 0x34 when I in turn I actually need 0x41.
OK, thats because int is for converting strings. You need to use struct.unpack
to convert the 4 bytes into an int.
You also need to figure out how many
This is what I have so far,
import struct
EncryptString=313B372C2E2C63362E2128
XorKey=41424344
key = struct.unpack(d, XorKey)
num_ints = len(EncryptString)/11
data = struct.unpack(%dd% num_ints,EncryptString)
The above code generates an error the my string must be a string length of
16
When
Isn't it better to use
if __debug__:
I thought such an if statement always evaluated to False when the python
program was run in OPTIMIZED (-o) mode?
Cheers!!

Thanks for your reply Dave. I am capturing the data off the network
(wireshark) and saving it in WinHex for testing. I am actually building a
socket to decrypt the data, so prior to implementing my logic in the socket,
I figured I would write the algorithm in a quick script. Here is what I

I've been happy with WingIDE on Linux, fwiw. I'm still
a TextMate fanboy (if you use a Mac).

Sweet nice tip I love this list. Thank you.

Ken,
Two recommendations.
1) Komodo Edit 5. Free edition available from Activestate.
www.activestate,com
2) Wing IDE 101 Free Edition from www.wingware.com
my favorite of the freely available IDE's.
Good luck,
Robert

This is different to what I expected, it is a string of ascii bytes
representing hex values.
Is that the real format of your data? If so we need to split it into pairs and
use
int() to convert it. Or is your real data a string of bytes that happen to

Greetings,
I recently started learning Python and I have written a script that uses
a shelf on Mac OS X using Python 2.6. I recently attempted to move the
directory over to my Linux system, which also has Python 2.6 installed,
and run the script there.
The script works fine, but the shelf does
