plz tell me what is brute force ??

what work this option ,

anyone explain it?.......

n cryptography, a brute-force attack, or exhaustive key search, is a strategy that can, in theory, be used against any encrypted data.[1] Such an attack might be utilized when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the task easier. It involves systematically checking all possible keys until the correct key is found. In the worst case, this would involve traversing the entire search space. The key length used in the encryption determines the practical feasibility of performing a brute-force attack, with longer keys exponentially more difficult to crack than shorter ones. Brute-force attacks can be made less effective by obfuscating the data to be encoded, something that makes it more difficult for an attacker to recognise when he/she has cracked the code. One of the measures of the strength of an encryption system is how long it would theoretically take an attacker to mount a successful brute-force attack against it.
Brute-force attacks are an application of brute-force search, the general problem-solving technique of enumerating all candidates and checking each one.

How to Configure PC for SL3 unlocking
1. Required hardware: ATI Radeon HD 5xxx or Nvidia CUDA graphic card
2. Recomendded hardware: HD 5850, HD 5870 or HD 5970
3. High hardware system: TWO Dual HD 5970

Note:
On Nvidia CUDA GPU graphic cards, price of card over performance is not the best one,
so we NOT recommend to use Nvidia CUDA cards.
But, if you have to much money and want to throw away some money,
our software also support this cards too.

================================================== =============================

About Bruteforce Unlocking times:

Average medium unlocking times
(e.g. if have 100 phones, this is total time spent to unlock this 100 phones divided by 100)

ATI HD 5850: ~55 hours
ATI HD 5870: ~43 hours
ATI HD 5970: ~24 hours
Dual ATI HD 5970: ~12 hours


- Please do NOT make confusion regarding Maximum Unlocking time or some ONLY ONE phone unlocking time.
- This times depends mainly on how lucky or unlucky you was on JUST ONE SPECIFIC phone.
- For that reason we can NOT provide/calculate this value for ONLY ONE phone.
E.g. sometimes you could be lucky and get code just after 5 minutes, sometimes you could be unlucky
and get code in some longer time (need search almost whole 15 digits key-space).
- BUT, based on statistical laws, if have enough phones (let's say 50-100),
we can aproximate the average medium unlocking time.
- Also we not want to publish some false informations regarding maximum times (like some "other teams" do),
or other kind of dirty-tricks (like max. 48 hours, but need spent few days by pressing one button until
you are lucky and get one "free-slot" on some OVERLOADED server).

Now, with SL3 Local Bruteforce and MxKey, Time Control is IN YOUR HANDS.
Of course, depends on how many phones you have to unlock and how much you want to spend on hardware.

Note:
- This system require Down-plugging x16 Cards in x1 Connectors (because of choosen low cost motherboard)!
- It is not very well known, but the PCIe specification electrically supports down-plugging a card
in a smaller link connector, such as an x16 card in an x1 connector!
- We will make very soon an manual how to do this (Down-plugging x16 Cards in x1 Connectors).
- If you are in verry hurry and want to build this "High hardware" with TWO ATI HD 5970, please consider
some additional 50-100$ in total price
(for an motherboard with two PCIe x16 slots and enough space between slots for two HD 5970 cards)

Total price: $1688
Estimated selling price after one year: $1300
Cost to own this hardware for one year: $388


--------------------------------------------------------------------------------------------------------

"Entry level hardware" and "Medium hardware" prices can be even lower, but we choose same chasis,
motherboard and PSU as on "High hardware" to allow possibility for future hardware expansion with smaller costs!
