* nwztools/upgtools: rewrite keysig brute force searchAmaury Pouly2016-10-27
| | | | | | | | | | | 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). Change-Id: Ied080286d2bbdc493a6ceaecaaadba802b429666
