OK now that we've captured the handshake all we need to do to crack the WPA key is to create a wordlist

2

a word this is just a list of words and that aircraft engine is going to go through and try each one

3

of these words.

4

I guess the handshake until it successfully determines the WPA key.

5

So the battery or your wordlist is the more your chances are of cracking the key if the password wasn't

6

there in your worthless pile.

7

You will not be able to determine the WPA key.

8

No one talks to list over the word list that you can just download and use.

9

Or you can create your own words is use in this video tutorial.

10

We're going to use a tool called Crunch.

11

It's basically just a script that you specify the characters that you want in the passwords and it'll

12

create all possible combinations of these passwords.

13

So the format of the command of user and crunch is crunch minimum maximum the minimum is the minimum

14

number of characters of the password that you want to create.

15

So you can say I want a minimum of four five six whatever you want maximum is the maximum number of

16

characters in the passwords characters.

17

You're going to specify the characters that are going to be used to create the passwords so you can

18

specify a b c d g all the lower letters and then you can write the capital letters and you can put numbers

19

you can put symbols.

20

So here you'll specify the part the characters that you want and then he is very useful if you know

21

part of the password.

22

It's a pattern.

23

So for example if you're trying to guess a password and you've seen someone type this past or so you

24

know for example it starts with an A and ends with a B.

25

So you can use the pattern option and tell the crunch to create passwords that always start with a and

26

with B and it'll put all possible combinations of the characters that you put in here.

27

So for example in here in this example we have crunch that we're going to create passwords of minimum

28

of six characters and maximum of eight characters and the passwords are going to be combinations of

29

the characters.

30

One two three four five six.

31

And these symbols is going to be stored in a file called wordlist and the pattern is this this password

32

or that are going to be created.

33

They're always going to start with an array and they're always going to end with B.

34

So all the passwords though you're going to see in the file are going to always start with a and with

35

B and they'll have all the possible combinations of the characters you specified here between the A

36

and B B.

37

So let's just run it here and create a sample wordlist.

38

I'm going to crunch and then we're going to make.

39

I mean your mom 0 6 and Maxim or six or let's say more for maximal six.

40

And just so that doesn't take a lot of time going to make it short.

41

I'm going to say I'm going to put the characters.

42

So I'm going to just put one two three a week.

43

I'm going to throw this and sample or just

44

so crunchie is going to create a combination of passwords minimum of four characters maximum of six

45

characters and it's going to create all possible combinations of 1 to 3 A B and it's going to start

46

all that in a file called sample wordlist.

47

Now we can read this file we can just say cat simple word list and we can see all the passwords that

48

are stored in this file now.

49

So that's all the passwords crunch created for us.

50

So you can see it was nineteen thousand three hundred and seventy five combinations possible from only

51

1 to 3 AB.

52

Obviously the bigger the password that you put the mark the more characters you put the more passwords

53

that you can make and the more space they're going to take.

54

So let's just have a look on the pattern option.

55

So it will go crunch that's a minimum of five and a maximum of five.

56

So all passwords I want them to be five Carter-Long and then I'll put the characters which are 1 2 3

57

A B like before.

58

And then I'm going at the T option which is the pattern and I'm going to say I want a password.

59

Start with an A and end with a B and I want all possible combinations of my characters between the A

60

and B B and then we're going to specify the output file and let's call it hotter'n wordlist

61

and you can see here it's going to create 125 passwords.

62

Let's have a look on them.

63

And as you can see here it's always starting with an name always ending with B.

64

So you can use crunch now to create your wordlist and in the next video we're going to use the wordlist

65

and the handshake files to determine the actual WPA key.
