This was a huge mess, the new is much cleaner hopefully.

nwztools/upgtools: rewrite keysig brute force search

2016-10-27T21:06:16+00:00

The new search has two new features:
- it takes advantage of the fact that DES keys are only 56-bit long (and not 64)
- it is now multithreaded
As a proof of concept, I ran it on the A10 series firmware upgrade and was able
to find the key in a few seconds using 4 threads. The search is still limited
to ascii hex passwords (seems to work on all devices I have tried thus far).

nwztools: cleanup the code

2016-08-30T07:21:05+00:00

There was a lot of copy and paste, and the code was just crap. This commit tries
to clarify the code and also document the encryption procedure. Hopefully I didn't
break anything.
