nt'': 1a7eaf35
ks2: 9b134452
ks3: 835b40a8
Found Key: [73 6e f5 16 ff ff]
but 9370cafd is not the uid the real uid is: ca fd ca 13
do you hear about this problem???
thanks

yeah it's no secret that the .py is somewhat crappy, i pointed it out at the time and provided a proper parser. However this python string searching was preferred.
the py uses very simple logic to find the uid it string searches for
93 20and then just takes the bytes on the next line from position 20 to 34.
It violates almost every rule, in sane programming, but that's the way it is.
