Now every time we use aircraft ngi regardless of the method.

2

Aircraft ngi will use the C.P. you or the central processing unit to process the passwords and try them

3

against the Hunchy.

4

So basically the processor or the C-p is what's being used in the tracking process.

5

Now this is usually the default behavior of most tools because the CPE is the brains of the computer

6

is the central processing unit and thus the default component that's used when the computer needs to

7

process data.

8

Now if we pause for a second I think a lot of computers also contain another processing unit which is

9

DGP to the GOP stands for the graphics processing unit and it's built and designed so that they can

10

carry out repetitive tasks very quickly.

11

For example rendering pixels on the screen is a very repetitive task because it literally loops over

12

each pixel on screen and displays data in it.

13

Therefore the process of key cracking is very similar in its essence to rendering pixels on screen for

14

example.

15

Basically it's a very repetitive task because we go through the wordlist and we take each password in

16

the word list and then try to test it against the handshake and see if it's valid or not.

17

So it's a very repetitive task.

18

And because the GOP views are optimized to carry out repetitive tasks very quickly they're actually

19

more efficient than simply use when it comes to cracking.

20

So if you have a good graphics card you can use that graphic card or GP you in the cracking process

21

instead of the C-p you.

22

And that way you'll be able to go through the wordlist and carry out the cracking process much faster

23

than if you would do it with the C.P. you and that's the main goal of this lecture I want to show you

24

how to use the GP and the cracking process instead of the C-p you and we'll see how fast that is compared

25

to the speed that we were getting with the C-p you know first of all before we do anything you need

26

to have a powerful GP you or at least a good graphics card.

27

We're going to use a tool called hash cut for the cracking process because aircraft engine does not

28

allow us to use the graphics card and the cracking.

29

I'm also going to do this from a Windows machine because most people use have drivers for Windows and

30

it'll be very difficult to install their drivers for Linux.

31

So if you're if you can install your driver for Linux then it's ok you can use hashcash from Linux exactly

32

the same way that I'm going to show it in this video but I'm showing you how to do it from windows because

33

it's actually much easier to install the drivers for a graphics card for Windows because most manufacturers

34

or release official drivers for Windows whereas when you go to Linux you might have to install third

35

party packages to get it to work.

36

So I have the Web site here for Hoshko.

37

I'm going to include in the resources now before you can use hash cat you'll have to download the driver

38

requirements for your GP you so you can see in here we have a list of the drivers that you need to download.

39

So if you have an AM DGP you you'll need to download the HMD radon software for Linux.

40

You'll have to download the MDG Depue pro driver and so on.

41

Now I'm on Windows so I'm just going to highlight this and I'm going to right click and search google

42

for it and you'll see the first results will come up with the right result.

43

So I'm just going to click it.

44

And then you can see I can download it from here.

45

And it is very easy.

46

Just double click the downloaded file.

47

Then next next next next.

48

And then your computer will restart and you'll have it installed.

49

Now I've already done all of that so I'm going to go back to Hosh cat and I'm going to go ahead and

50

download the binary of hash cut.

51

And as you can see now that's downloaded for me and it's gone in the download directory.

52

So it's zipped file it's a seven zip file you'll need an archive manager to open it.

53

I already have.

54

When you are installed so I'm just going to double click it and that's going to be opened in winter.

55

Now I'm going to click it's directory here click on extract to uncompress it and I'm going to choose

56

to uncompress it in my C directory.

57

I'm going to hit OK and that will basically put the files for hashcash in my C. directory.

58

Now the next step is going to be converting my handshake to a file that's compatible with hash cut.

59

Now when we capture the handshake as we've seen in all the previous lectures it's usually stored in

60

a file that has a copy extension so that c.a.p.

61

Now hashcash can't read the files so we'll have to convert this to a file that's compatible with Hauschka.

62

Now we can do that very easily using an online tool made by hashcash.

63

So I have tried here and again I'm going to include its link in the resources.

64

Now all you'll have to do is just go on Choose file choose the cap file that contains the handshake.

65

Click on Open and then put the network name in the SS ID field.

66

Now my network name is already started in there so it's UPC 7 2 3 7 6 2.

67

I'm gonna click on convert now as you can see now this automatically changes the file type to a hate

68

cap x file and it automatically downloads this for me as well.

69

So if I go to my downloads directory you can see that I have a new file here and it has a hate C-cup

70

X extension.

71

This is the extension that hashcash can read and understand.

72

Now I'm just going to rename this file and I'm going to call it handshake so that it's easier for us

73

to know.

74

Now we're all set.

75

I have my hand shake here and I also have my word list right here which is called Rock Q And I'm just

76

going to copy both of these files

77

and put them in the same directory as hashcash.

78

So I put hashcash in C so it's in my PC C and it's called Hauschka at and I'm going to paste the word

79

list on the handshake in here.

80

Now we're all set.

81

We have our wordlist on the handshake on the same directory as hashcash binary.

82

So now we're ready to use hash cut and all we have to do is we have to navigate here from Windows command

83

prompt then run Hauschka out against this handshake with the dictionary that we just copied.

84

So in the next lecture I'm going to show you how to use hash cut from the windows command prompt to

85

crack the handshake using the GP you instead of the C-p you.
