KLicence Brute-force Tool v1.0 (2012/10/06)
Copyright © MAGiC333X


[RELEASE NOTES]
Initial release of the KLicence Brute-force Tool.
Version 1.0, built on October 6, 2012 using Microsoft Visual C++ 2010 Express.

Use this program with caution. I will not be held responsible for any damage
caused by (the use of) this program or it's source code.

Source code is included as a donation to other developers.

Files included in this release:
- Compiled program (Win32): 'klicencebruteforce.exe'.
- Example ps3keys file: 'keys'.
- This README file: 'README.txt'.
- Source code: 'klicencebruteforce-src-1.0.rar'.
- GPL v3 for used libraries: 'gpl-3.0.txt'.

Special thanks to:
Asure (PS3Hax) - for the first steps in this subject and gaining my interrest.
PS3DevWiki - for the information on SELF files and NPDRM decryption algorithm.
naehrwert - if SCETool source code was available, i wouldn't have made this.


[DESCRIPTION]
This program will try to decrypt the metadata info of a SELF file that's been
encrypted using a developer KLicence, by trying all the possible keys in the
user-specified input keydata file. If the input keydata file contains the key
to decrypt the metadata info, then the key will be found. When a working key is
found, it will be written to the console.

It is VERY fast! On my Core2Quad Q6600 @ 3.2 GHz it does ~770.000 keys/second,
utilizing only a single thread/core. Moreover, it scales perfectly when running
multiple instances concurrently.
So, if you have a quad-core processor and you split your input keydata file
into four equally sized parts and run four instances of this program, each
using one part of the input keydata file, it will give you a nice x4 speedup!

This program is built for speed, not compatibility. This means that there is a
great chance that some SELF files won't be processed correctly. If this is the
case, try processing it with option '--minimize-validation' enabled. If it
still doesn't work, use option '--npdrm' together with '--metadata-info'. This
will result in the SELF file not being used or validated (the argument is still
mandatory though). This way you can force the program into brute-forcing the
metadata info of any SELF file.

Input ps3keys file must use format as used by SCETool. A sample ps3keys file is
provided: 'keys'.
The program will try all keys in the ps3keys file with name prefix 'NP_' as
possible KLicence keys before starting the brute-force attack. This has the
advantage that previously found keys can be added to the keys file. For an
example, see the included keys file: it has the InfinityWardKey added to it as
'NP_infinitywardkey'. Also, you can use comments in the keys file by starting a
line with '#' (just like an INI file).

Input keydata file is a binary file. This is the file that is used for the
brute-force attack. If the KLicence key is in this file, it will be found.

For more help on how to use this program, see the USAGE section below.


[CHANGELOG]
Version 1.0 (October 6, 2012)
- Initial release


[SOURCE CODE NOTES]
Source will build using Microsoft Visual C++ 2010 Express.

I've tried to keep the code portable, so making it compile on Linux shouldn't
cause too many problems. This is untested, however.

There is some room for improvement:
- Thorough testing for bugs/flaws.
- Don't read input keydata file fully to memory.
- Make brute forcing multi-threaded (it will scale perfectly!).
- Use another (faster) AES library to improve performance.
- Refactor: make coding style consistent.

Libraries used:
aes.h/aes.c - AES library from PolarSSL, GPL v2+.
common.h - Endianness swapping library by Youness Alaoui (KaKaRoTo), GPL v3.
Code may contain some parts from euss's ps3tools/fail0verlow tools, any licence
that came with these 'borrowed' source parts remain in effect.
A copy of the GPL v3 licence is included.

My source code is not protected by any licence, feel free to use it any way you
want. If improvements are made to the source code, I would be very pleased if
those improvements are made public.


[USAGE]
klicencebruteforce.exe [options]

Options                     Parameters       Decription
-n, --npdrm                      Overrides NPDRM key and IV used
                                             for decryption. Using this option
                                             in conjunction with '-m', causes
                                             skipping of even more self parts.

-k, --klicdeckey                      Overrides KLicenceDecryptKey used
                                             for decryption. This key will be
                                             used instead of 'NP_klic_key' from
                                             the ps3keys file. If used in
                                             conjunction with '-npdrm', then
                                             ps3keys file won't be used.

-m, --metadata-info                  Decrypt specified metadata info.
                                             If this option is used together
                                             with '-npdrm', then self file will
                                             not be used.

-i, --progress-interval              Sets the progress update interval
                                             (default=1000).

-p, --disable-progress                       Disables periodic progress updates

-x, --minimize-validation                    Minimizes validation. Parts of the
                                             self file that are not necessary
                                             for brute-forcing are skipped and
                                             most validity checks are disabled.

Parameters                  Values           Decryption
file                        filename         If filename contains spaces use
                                             quotes. Example: "file name.xyz".
millis                      decimal          Duration in milliseconds.
key16                       16 bytes hex     16 bytes key, hex notation.
key32                       32 bytes hex     32 bytes key, hex notation.
iv                          16 bytes hex     16 bytes IV, hex notation.
data64                      64 bytes hex     64 bytes data, hex notation.
