00:00:00,360 --> 00:00:01,740

Hello and welcome.



2

00:00:02,160 --> 00:00:09,150

So in the previous lesson, we already use dynamic analysis to confirm what we found in the static analysis



3

00:00:09,570 --> 00:00:16,000

and we and also we managed to fish up the algorithm and confirm it using dynamic analysis.



4

00:00:16,740 --> 00:00:20,580

So now we are going to create Guijin using Python.



5

00:00:20,940 --> 00:00:27,540

And you can go to this online python compiler or any others, quite a number of them.



6

00:00:27,990 --> 00:00:29,180

And Kinescope.



7

00:00:30,100 --> 00:00:37,390

You can download this from the resource section, you had to type all this in, so let me explain what



8

00:00:37,390 --> 00:00:37,910

I did here.



9

00:00:38,530 --> 00:00:43,090

So the first line is to import time on you, as did.



10

00:00:44,350 --> 00:00:50,810

The second line is to ask the user to enter the name so you save it in the variable name.



11

00:00:52,000 --> 00:01:02,450

This line, who now is the current debt and saving a variable X and then this tree line is just a straight



12

00:01:02,890 --> 00:01:06,310

and show the year, the month and a day.



13

00:01:07,060 --> 00:01:11,680

And you can actually in if you do doing this important one is line 14.



14

00:01:12,430 --> 00:01:20,010

Line 14 is where we use a form specify which we up from analysis over here.



15

00:01:20,350 --> 00:01:28,650

This is a form specify it and then we reconstruct this Iraqi based on if I may specify.



16

00:01:29,470 --> 00:01:38,470

So here the first form I specify X will be a name because we already confirm during our debugging dynamic



17

00:01:38,590 --> 00:01:49,900

analysis that differs from specify e a name and then your second one is your year plus one, two, three,



18

00:01:49,900 --> 00:01:52,560

four, which coming from here.



19

00:01:52,570 --> 00:01:57,550

The second one is your year plus one, two, three, four.



20

00:01:59,830 --> 00:02:02,870

And then the third one is your money.



21

00:02:03,580 --> 00:02:08,440

So for money, I, Stutman for you is here, plus one, two, three, four.



22

00:02:09,590 --> 00:02:15,080

And the last one would be your day, so the day will be extended.



23

00:02:15,980 --> 00:02:16,340

All right.



24

00:02:16,350 --> 00:02:17,450

So we can it now.



25

00:02:19,710 --> 00:02:20,760

We can stop this.



26

00:02:24,400 --> 00:02:30,370

And come here and run our economy five.



27

00:02:35,630 --> 00:02:40,540

OK, so now you are going to enter a name secret.



28

00:02:42,320 --> 00:02:44,040

So what do you think will be this year?



29

00:02:44,090 --> 00:02:44,420

Key?



30

00:02:46,280 --> 00:02:48,290

All right, we can use our Keagan.



31

00:02:50,040 --> 00:02:56,850

So let's come back to al Qaeda and he asked for the name he entered



32

00:02:59,370 --> 00:03:09,110

into and you can see the KIGEN has generated Shiraki as three to five, five, six on it.



33

00:03:10,190 --> 00:03:19,710

So let's try to correct three, two, five, five, six on the crack, the three, two, five, five,



34

00:03:19,730 --> 00:03:21,200

six, one, eight.



35

00:03:23,310 --> 00:03:31,260

Well done, so our kitchen looks OK, so in this lesson, we've already learned how to do static analysis



36

00:03:31,470 --> 00:03:41,550

to analyze the algorithm and put in our relabelling of the variable names that we suspect to be the



37

00:03:41,550 --> 00:03:44,570

correct variables for Niemans here.



38

00:03:44,970 --> 00:03:52,080

And then we also analyzed the construction of the zero key and we only had suspicions.



39

00:03:52,530 --> 00:03:56,430

And then we use dynamic analysis to confirm how hypotheses.



40

00:03:56,880 --> 00:04:03,730

In the end, you confirm that he works and then we went on to create KIGEN using Python.



41

00:04:04,380 --> 00:04:07,880

So I hope this was instructive.



42

00:04:08,340 --> 00:04:13,800

So go ahead and try this now and you can see the output here two to one.



43

00:04:14,100 --> 00:04:24,930

He's coming from the year after year six is your month, which is June, month 18 is Xactly and then



44

00:04:24,930 --> 00:04:32,160

here last one is he promised specify combining all the above to create Yoshiaki.



45

00:04:32,670 --> 00:04:34,290

So that's all for this lesson.



46

00:04:34,870 --> 00:04:36,660

Thank you for watching.
