WEBVTT 00:00.450 --> 00:06.780 High now in this lecture we'll create a positive decree for cracking Wi-Fi a password. 00:06.780 --> 00:13.200 We complete a handshake capture with these networking this previous lecture and now you're going to 00:13.200 --> 00:14.830 create password dictionary. 00:15.210 --> 00:16.730 First to the wife Ania quote. 00:16.950 --> 00:18.610 So let's get into the work. 00:18.700 --> 00:21.780 We are using crunch tool for this matter. 00:21.780 --> 00:26.210 So type crunch and we need to common that too. 00:26.220 --> 00:29.370 What is the minimum and the maximum length of the password. 00:29.580 --> 00:38.430 So we are typing three as a minimum and fibres a maximum then common the tool what types of password 00:38.430 --> 00:39.930 combination we want to create. 00:39.930 --> 00:49.470 Like numbers letters or spatial characters then we add typing dash 0 4 output put the password and typing 00:49.470 --> 00:53.850 the name of the file where we want to save the password then proceed to. 00:53.910 --> 00:57.060 And the password will be create am saving the file. 00:57.390 --> 01:01.340 But now I create damn a password that it can stand better. 01:01.650 --> 01:04.560 After that we will work on the real one. 01:04.560 --> 01:10.710 So let's smoke and this is the password list that we created using all combination of three to five 01:10.710 --> 01:11.770 characters. 01:11.940 --> 01:17.390 And now we are deleting these because this one is a demo and now we are creating another one. 01:17.400 --> 01:22.880 In advance we if we notice something about a victim then we can apply this method. 01:22.890 --> 01:29.250 Like if we know about the victim password length then we can type in the common line minimum and maximum 01:29.250 --> 01:29.600 length. 01:29.700 --> 01:37.800 And if we know victims Bert the Bert the year or in his pay show day or spatial persons name or company 01:37.800 --> 01:45.450 name or anything related to the secret or special that victims could be using the password then we can 01:45.480 --> 01:53.160 apply these characters that we already know as first four or five characters or at least four or five 01:53.160 --> 01:54.300 characters. 01:54.300 --> 02:00.570 And if you think this is complicated towards 10th what I am talking for and then let's say in a practical 02:01.170 --> 02:08.790 and now we are doing copy and paste the same common that we did before and only teasing and using the 02:08.790 --> 02:16.020 characters that we don't know about victim password and typing at the rate of as that is that we don't 02:16.020 --> 02:17.790 know but we want to know. 02:17.990 --> 02:24.320 Okay here we're going to create only five characters password list for test purpose that you can understand 02:24.340 --> 02:24.900 easily. 02:24.960 --> 02:28.890 So press Enter then password you'd be saving the output file. 02:33.060 --> 02:36.820 This is the password last week for eating and now your ability. 02:36.840 --> 02:43.580 These fine because this one is also a demo file and now I'm gonna tell you the benefit of these advanced 02:43.590 --> 02:44.680 method. 02:44.730 --> 02:51.150 This is the method for creating the password so fast like if you know some purpose of that password. 02:51.150 --> 02:57.930 We could make it sure when the password is so long like 15 or 20 characters we only need to find out 02:57.930 --> 02:59.600 of which part of that password. 02:59.610 --> 03:05.490 We don't know like password is 15 characters and we already know five of them. 03:05.610 --> 03:13.470 Then we have to go only for 10 characters and it's much easier and time consuming than 15 characters 03:13.500 --> 03:14.050 right. 03:14.100 --> 03:15.080 Makes sense. 03:15.120 --> 03:19.250 Now we are going for the real one that we need to crack. 03:19.260 --> 03:28.370 Suppose we know the passwords Lent is 13 so we are typing 13 as a minimum and maximum characters. 03:28.380 --> 03:39.550 Then typing numbers from 1 to 9 you can write any of the numbers from 1 to 9 and 0. 03:39.760 --> 03:42.240 It takes more time to create passwords. 03:42.400 --> 03:48.160 So I live it because a zero is not a part of my victim password that I am looking for. 03:48.160 --> 03:53.650 You have to write all the numbers and letters that is necessary for your password that you are looking 03:53.650 --> 03:54.490 for. 03:55.050 --> 03:56.300 And to then type. 03:56.300 --> 04:02.760 Later here I am typing what letter is necessary for my password that I'm looking for. 04:02.760 --> 04:08.550 Suppose I know a little bit of that victim password and I am doing these to make it fast in the course 04:08.550 --> 04:09.600 video. 04:09.600 --> 04:13.730 If you don't know about the victim password characters war you need it. 04:13.800 --> 04:24.080 You should type A to Z then typing dash t option then typing what do you know about the password and 04:24.260 --> 04:27.130 then typing what he don't know about the password. 04:27.260 --> 04:36.630 As in at the rate of there are six characters that we don't know so we use six at the rate of. 04:36.630 --> 04:39.810 And we know seven characters as an me. 04:39.930 --> 04:42.210 So we typed then presenter 04:45.190 --> 04:46.590 is creating password. 04:46.900 --> 04:49.180 But here is the mistake I made. 04:49.180 --> 04:57.800 I didn't comment for output file where to save so it's just creating password not saving so I'm correcting 04:57.800 --> 05:10.740 my common again and typing dash 0 4 output and typing directory friending then presenter now which shows 05:11.070 --> 05:17.460 password security file will be two hundred twenty four megabyte and password combination will be more 05:17.490 --> 05:21.600 than 16 million and it's done so quickly. 05:21.810 --> 05:28.770 If we want we can make more password combination and if we want to make a large number of password dictionary 05:29.100 --> 05:35.970 and crack then we have to spend a long time or so deep in on your need to try and hear every possible 05:35.970 --> 05:42.600 combination has over move before the password that is generated because of we comment of admin on the 05:42.600 --> 05:47.950 comments line before we created the password get it all right. 05:47.970 --> 05:53.910 We knew only seven characters out of 30 enough that password we didn't know the last six characters 05:54.090 --> 05:58.640 of that password but now we know all the characters of that password. 05:58.680 --> 05:59.920 So let's check it. 06:00.030 --> 06:10.210 Is it here or not Yeah it's here on thirty four million thirty four thousand and three hundred and Twelfth 06:10.220 --> 06:11.140 number line. 06:11.630 --> 06:18.870 So we can crack these password after trying this large number of time and I hope you understand. 06:18.980 --> 06:21.460 Sounds complicated but it's not so much. 06:21.530 --> 06:21.890 Okay.
