And the previous lecture we covered how to store our progress when going through a large wordlist.

2

This allows us to pause and Richoux so that we can stop our cracking session and then come back at a

3

different time and then start the session from where we left which is very handy when we have a large

4

wordlist.

5

Another issue that we might face when you use an a large wordlist is the disk space.

6

So a large word list would basically just take a lot of space from our desk.

7

The solution to this is to generate the wordlist use and crunch and pass it on the fly to aircraft N-G.

8

So basically we're going to be use in crunch to create the wordlist like we've seen before but instead

9

of saving the wordlist on disk we're going to make it produce the wordlist on screen.

10

So the result is going to be very similar to what we got when we opened our wordlist with John the Ripper

11

and the previous lecture and then we're going to pipe that output to aircraft energy which will read

12

that as input and process the wordlist on the fly as it's being generated on crunch.

13

This way the wordlist will not be stored in a specific file and it won't take a lot of disk space.

14

Now let me show you how to do that and it's going to become more clear.

15

So first of all before I do the whole command I'm just going to show you the command that we usually

16

use with crunch so easily do crunch and then we do the minimum number of characters followed by the

17

maximum number of characters.

18

And I'm going to set both to eight because this is the minimum number of characters that you can use

19

and with WPA a password.

20

Then we usually specify the characters to use to generate the wordlist.

21

Now I'm not going to specify any characters right now because I want to use all the characters so if

22

I don't specify any characters Cranch will use A B C D F G all the way up to Z by default.

23

So all I have to do now is just do minus 0 to specify the file to save the wordlist too.

24

And let's just say to all takes the now I'm going to hit enter and as you can see this file is going

25

to be huge is going to be one terabyte one thousand seven hundred fifty gigabytes.

26

And this much megabytes.

27

So it's going to be a huge file.

28

And I actually don't have enough space on my desk to store that file so I'm going to do Control-C And

29

what I'm going to do right now is I'm going to run the same command and I'm just going to omit the minus

30

argument.

31

So what I'm doing right now is crunch.

32

I'm telling it that I want you to generate passwords of length 8.

33

And I didn't specify any characters because I wanted to use all characters A to Z.

34

Now if you want to use specific characters you can just type them in here A B C D F G 1 two three.

35

As I showed you before.

36

So I'm going to hit enter with this and you'll see that it's still telling me that this is going to

37

take one terabyte 1750 gigabytes but it's displaying the results on screen.

38

It's not storing it in a file.

39

And if we let this run for a long period of time it'll actually display all possible combinations of

40

characters that have a length of eight characters and contain the characters A to Z.

41

Now I'm going to do Control-C to this because this is not useful for me.

42

I'm just doing this to show you.

43

But if you notice the output right now is very similar to the output that I got in the previous lecture

44

when I opened my wordlist use and John the Ripper when we were doing the pause and resume process.

45

So you can see that the result is being displayed on screen for Amena which is very cool.

46

So what I want to do right now is I want to pipe this result.

47

So we usually pipe using this character like we've seen before.

48

So what I want to do right now is I want to pipe the result of this command to aircraft engine.

49

And like I said earlier this command is producing a result very similar to the result that we got from

50

John in the previous lecture which means the output right now is exactly the same output that we got

51

from John in the previous lecture.

52

So the command that we're going to be passing this to can be exactly the same command that we used in

53

the previous lecture.

54

And it should work.

55

Therefore all I'm going to do is I'm going to do aircraft and G and I'm going to give it the OBSS idea

56

of my target network then I'm going to give it minus W.T. give it the wordlist.

57

And just like I did in my previous lecture I'm going to do a dash to tell it that use the output of

58

the previous command as the input for the wordlist.

59

Then I'm going to give it the handshake file which is called handshake 0 1 cup and that's it.

60

I'm good to go.

61

So we're doing a crunch.

62

Eight eight.

63

To generate passwords of length 8 from 8 izzi.

64

And again you can use any crunch command right here you can use any combination any characters any pattern

65

exactly the same way that I showed you and the crunch lecture then we're not using the minus option

66

because we don't want to save anything on disk.

67

We want the result to be displayed on screen and then we're piping that result to aircraft N-G.

68

Now two aircraft ngi were given that actually should not have a space here.

69

So we're giving it the best idea of the target network we're given at the dictionary and we're not actually

70

given a name for the dictionary we're only giving it a dash.

71

And this is because we're telling it that I want you to use the output of the previous command as the

72

input.

73

So this is exactly like we did in the previous lecture and then we're given a file that contains the

74

handshake.

75

Now if I enter I misspelled aircraft.

76

So it's like this.

77

Now if I hit enter

78

and as you can see now aircraft engine is working it's taken the passwords generated by crunch on the

79

fly and using them as the dictionary.

80

So the wordlist is not being stored on my desk my desk will not get full.

81

And this way we'll be able to use huge word lists for cracking.

82

The only problem right now is this word this is really really big and there is no way we can go through

83

it within one session.

84

So it would be great if we can save our progress and be able to stop and continue whenever we have the

85

time.

86

So in the next lecture I'm going to show you how to combine what we learned in this lecture and in the

87

previous lecture so that we can use a huge wordlist and use it directly with our crack energy without

88

saving it on disk and also be able to stop and rescue our progress.
