Hello All

All i need a Computer with 4x6990 Cards.
what i want to Know

Motherboard that can support 4 6990 Cards
Power Supply that support this all.
i want to put this System Open so No case. i am planning to build a Wood Case for this.
Cooling supply etc.
I am New 7 i have no idea of Computer stuff. so i am sure i will have a Super Doper Configuration.
Plus Kindly Share your ideas also. for Better performance & Quick result..

Cracking Nokia SL3 with oclHashcat-lite

Background

This can be described as an attack type suitable for mobile phone hash cracking. The attack name is 'borrowed' from the Nokia mobile phone security type. Method is to use hash cracking tools to extract code from Nokia phone hash developed by security researcher Alex on gsm scene known as bphreaks.

Cookbook

If you want to fully understand how it works you need to read and fully understand the following articles:

Mask attack
oclHashcat-lite
oclHashcat, Catalyst and ForceWare
Distributing workload in oclHashcat-lite
HCCAP format description
step-by-step howto

AMD Users only: Get latest catalyst driver! Minimum 11.4. This step is absolutely neccessary otherwise you will not find the code and you will not get an error message.
Get oclHashcat-lite v0.6 from its homepage and unpack it.
Open a command shell window and cd to the oclHashcat-lite installation directory.
Get your hash (SHA1). Its a 40 char hex-encoded string and looks like this: 21B1E417AF2DE6496772BCC2FE33D2593A9BB7A0
Get your salt (IMEI). Its a 15 char hex-encoded string and looks like this: 351523047837342 but you only use the first 14 chars from it. The last digit is just a checksum and we dont use it.
Prepare your salt. Prepend and Append 00 to the salt like this: 003515230478373400
The following command starts oclHashcat-lite. The string looks complicated but its static, it does not change. The only thing that changes is your hash and your salt. A smart user would put it into a .bat file!
oclHashcat-lite64 -m 1900 -n 80 -1 00010203040506070809 --outfile=out.txt 21B1E417AF2DE6496772BCC2FE33D2593A9BB7A0:003515230478373400 ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1
NOTE: The linux command is exactly the same.

I will now explain the parameters so you know what you are doing:

oclHashcat-lite64: The program name itself. If you have an 32 bit OS then you should use oclHashcat-lite32 instead.
-m 1900: This sets the hash-type of oclHashcat-lite. 1900 stands for SL3.
-n 80: This is the workload-amplifier and its the most important flag that controls the Performance of the program. If you want more speed, raise it. If you want less speed, lower it. This is if your desktop is lagging too much.
-1 00010203040506070809: This binds the charset to our custom charset 1. SL3 uses only a small charset of ten chars (0-9, binary encoded). We have to encode it in HEX, thats why they all have a leading zero.
--outfile=out.txt: This is where the cracked pass is stored.
21B1E417AF2DE6496772BCC2FE33D2593A9BB7A0:003515230478373400: The only thing that changes.
?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1: our “mask”. 15 times ?1 (which ist custom charset 1 we bound before)
Hardware

SL3 always uses the same algorithm and data. Because of that it's always a known max time till exhaust. For example for 2xHD6990 clocked to 880Mhz max time to finish all of the 100% available key-space will be ~1 day 11 hours. Because we have fixed hash data and fixed salt all calculation speeds depend only on our hardware, no brains involved 🙂

Queue multiple Hashes

To attack a few hashes one after another we create bash (on Linux) or batch (on Windows) files. These files are intended to run commands line by line.

Linux example:

export DISPLAY=:0
export LD_LIBRARY_PATH=$HOME/AMD-APP-SDK-v2.4-lnx64/lib/x86_64

./oclHashcat-lite64.bin -m 1900 -n 800 -1 00010203040506070809 --outfile=351514044968571.txt --session=35151404496857_1 514D1FCDE9231B61DAD191F7BC7675B87D8628B5:003515140449685700 ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1
./oclHashcat-lite64.bin -m 1900 -n 800 -1 00010203040506070809 --outfile=355933045509554.txt --session=35593304550955_1 B928680D8D7B1242BEBC8B7AC24FF2B90198E213:003559330455095500 ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1
Commands explained: tbd,

Very important parameter here is --session as it creates different restore files for each session, we have no risk of losing earlier restore files because of problems like overheating.

tbd, explain simple batch files and why they can cause problems.

Why the "salt" is not what you think it is

There is a big and important difference in the word “salt” regarding how SL3 describes it and how the hash-cracking community defines it.

Since hashcat is a product of the hash-cracking scene we are using our wording.

The hashcracking scene defines a salt as some data (usually a random string or the username) which is mixed together with the plaintext password while calculating the hash. How this mixing is done in detail differs on the algorithm implementation.

The salt value is stored together with the hash value. Each hash value hash its own salt value. This makes salts a very efficient solution to avoid multihash cracking and precomputing hash tables.

From the hashcat view on SL3 cracking, the “salt” is only the 14 digit IMEI number (plus the static prepending and appending zero values).

The SL3 scene defines a salt as the last four (hex) digits of the plaintext password (the mastercode). The IMEI is just the IMEI.

A graphical view on this detail:

H = Hash
P = Plaintext password
S = Salt
I = IMEI
Hashcracking scene:

HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH:00SSSSSSSSSSSSSS00:PPPPPPPPPPPPPPPPPPPPPPPPPPPPPP

SL3 scene:

HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH:00IIIIIIIIIIIIII00:PPPPPPPPPPPPPPPPPPPPPPSSSSSSSS

Restore session

tbd, explain --restore and --session and what can go wrong in combination with queue's

Why "random salt" sucks

tbd, explain the true random mastercode generator

I like your vision, Its great..........almost like the new world order.... I like it..

I have seen multiple 6990 in action, and i dont think they perform that well together......

Grotts ... saving the polar bear one hamster wheel at a time..cudos.

Welcome Graaan .. new member...
lots of info ... will take some do'n to digest .. for me anyway..
i only speak english ... well .. sort of..hahhaa

somebody translate ?
i have no idea what you are talking about .. until u get to
strapping 4 79's down ... that has my attention..haha

grotts,, u sure ? thats a shame.

best of luck Graaan .. dont forget to come back with
pics ... lots of pics .... Please.c.

I guess a ROG Xpender will be a good start, do they fit on the RIVE or is Asus made, or plan to make one for the RIVE ?

I'm better stay away of this tread, I may be tempted to build one too

This is for Unlocking Nokia cell Phones.
it is Legal & Many people using this method to unlock Nokia Phones.

here are some configurations people Built and The are working on it.

This is GPU Estimations

here is Person who is Using

Intel i7 CPU
500 GB - Hard DRIVE
8GB - DDR3 RAM
900 Walt - POWER SUPPLY
HD5970 4GB ( LIMITED EDITION ) Graphic Card ( 2 in each PC

Speed getting : 35-36 sec per salt

GPU Usage with Brute Force : 98%
GPU Temprature : 77-80%

Overclock Set to 900mhz
Memory Clock 1200mhz

I hope you people have idea what i m trying to build

Later i will add more details

Dear All with 2 x 6990 Cross Fire and over Clocking we found Code in 1 day, 20 hours, 10 hours.
i want this process more Fast.
So please Guys Share your Experince and Tell me What i do which system will be Great.

You should look on the side of peoples who make mining ( bitcoin ) they have similar system with AMD GPU, If you don’t want burn power connectors on the motherboard, you need to choose a model with extra connectors for the GPU, in your case the Rampage IV extreme will be a good choice, you will need also 2 PSU, 1 is not enough, they make an adaptor to power on the second PSU at the same time as the first one.

the psu adaptor look like this one
