nwztools/upgtools: misc fixes

2017-04-25T01:23:57+00:00

* added KAS for nwz-x1000 (extracted from an NWZ-X1060 via "get_dnk_nvp kas")

* hint that -o is needed when extracting

nwztools: cleanup crypto, switch MD5 to Crypto++

2017-01-04T16:05:15+00:00

We already use Crypto++ for DES anyway, and using OpenSSL is not great because
of its incompatible licence.

nwztools/upg: move upg handling to its own file, completely rework kas handling

2017-01-04T16:04:38+00:00

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

nwztools/upgtools: add more brute force algorithms

2017-01-04T16:04:19+00:00

Allow to search for hex with upper case and alphanumeric. This is *much* slower
of course.

Add KAS for NWZ-E470

nwztools/upgtools: cleanup

2016-11-11T15:07:14+00:00

There is no need to store the key and sig since those are derived from the KAS
anyway.

nwztools/upgtools: sanitize series name and add keys

2016-10-31T16:51:18+00:00

Unify series names: e46x -> e460 to be consistent with Sony' name. Add keys
for various players that were cracked using upgtools. The real KAS would need
to be extracted from a target but at least we can open/create firmware upgrades.

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.

upgtools: add NWZ-E45x Series key and signature

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

Also fix a typo in the script makefile
