00:00:00,830 --> 00:00:08,090

All right, so here you can see that I'm on this website, Tools for new Starcom, I know this website



2

00:00:08,090 --> 00:00:12,620

name is very funny, but apparently that's the best hashing tool do right now.



3

00:00:13,430 --> 00:00:15,740

So let's calculate the hash.



4

00:00:15,740 --> 00:00:18,920

Let's start with MI five, which we have seen.



5

00:00:19,850 --> 00:00:22,910

So let's say I want to write.



6

00:00:23,210 --> 00:00:25,790

I love cyber.



7

00:00:27,270 --> 00:00:28,200

Security.



8

00:00:28,230 --> 00:00:35,220

All right, I love cyber security, not that I have.



9

00:00:35,760 --> 00:00:38,140

You know, what I've written is Somalia.



10

00:00:38,150 --> 00:00:38,970

It's Lorqess.



11

00:00:38,970 --> 00:00:42,110

And now let's see, I hash this, OK?



12

00:00:42,720 --> 00:00:45,030

You can see this is the hash resiled.



13

00:00:45,090 --> 00:00:46,910

OK, this is the hash.



14

00:00:46,920 --> 00:00:47,380

What is it?



15

00:00:48,030 --> 00:00:51,600

Just keep in mind about this has risen because we are going to need it.



16

00:00:51,900 --> 00:00:54,240

One F seven C five.



17

00:00:54,240 --> 00:00:54,760

One five.



18

00:00:54,790 --> 00:00:57,000

You have to remember this all.



19

00:00:57,000 --> 00:00:58,140

You can shoot it down.



20

00:00:58,140 --> 00:01:00,330

I love it for a couple of seconds.



21

00:01:04,760 --> 00:01:14,060

All right, now what I do is separate cyber and security and now let us see if the hash value changes.



22

00:01:15,480 --> 00:01:23,020

Of course, it has changed, you can see it has changed, the hash value has changed.



23

00:01:23,400 --> 00:01:26,280

So if you see this hash value you.



24

00:01:28,540 --> 00:01:38,390

One five seventy five, and if I give a speech are right here, the hash value is completely changed.



25

00:01:39,730 --> 00:01:43,240

So this is the hash.



26

00:01:43,250 --> 00:01:50,500

So even if you change one single bit, the entire value is going to change.



27

00:01:50,530 --> 00:01:50,950

OK.



28

00:01:52,690 --> 00:01:56,800

Another to say, I write, I want.



29

00:01:57,890 --> 00:01:59,090

To loan.



30

00:02:00,260 --> 00:02:07,670

Cryptography, I won't learn cryptography now you can see this hash value the length of this hash value,



31

00:02:08,000 --> 00:02:12,040

there is not as a two as the two.



32

00:02:12,050 --> 00:02:15,640

So you can see these are the number of hash.



33

00:02:15,650 --> 00:02:16,520

Who Ghadames.



34

00:02:16,910 --> 00:02:20,240

Let's go to a set of two, which is two fifty six.



35

00:02:20,720 --> 00:02:21,910

And let's hash this.



36

00:02:22,820 --> 00:02:25,210

Just see the hash.



37

00:02:25,700 --> 00:02:28,970

OK, just see the length of this hash.



38

00:02:29,490 --> 00:02:35,480

All I do is again I write I and again I'll hash this.



39

00:02:36,510 --> 00:02:46,230

It's going to change, right, and even let's see, I copy all this and irrespective of my input, irrespective



40

00:02:46,230 --> 00:02:53,130

of my input, the length of the input output is going to remain the same length.



41

00:02:53,820 --> 00:03:00,720

This is one of the most important properties of hash that irrespective of whatever length of input you



42

00:03:00,720 --> 00:03:05,020

give, the hash output is always going to be a fixed length.



43

00:03:05,490 --> 00:03:11,520

So as you can see, even if I remember this, even if I remove this, I'm sorry, the hash is going



44

00:03:11,520 --> 00:03:12,120

to teach.



45

00:03:13,010 --> 00:03:14,420

So this is how.



46

00:03:15,800 --> 00:03:23,120

Attackers, you know, carry out hashish and now you might ask a question, if you already have MI5



47

00:03:23,120 --> 00:03:25,850

in place, why do I need a city to physics?



48

00:03:26,570 --> 00:03:32,300

Well, even attackers can have a brute force attack and find out both attacks.



49

00:03:32,300 --> 00:03:39,980

But the more and the greater the length of the hash, the greater the size of the Indian got them,



50

00:03:40,490 --> 00:03:43,460

the more it gets difficult to crack the hatch.



51

00:03:43,490 --> 00:03:52,240

And as such, it is almost impossible to crack because no one has yet cracked a city to look at them.



52

00:03:52,880 --> 00:04:00,950

You're not going to dive deep into the algorithm because it's a lot of technical and mathematical.



53

00:04:01,280 --> 00:04:08,390

And since the scores is for people who want to get an overview of information security, I suggest that



54

00:04:08,390 --> 00:04:10,470

this is more than enough.



55

00:04:10,490 --> 00:04:10,880

All right.



56

00:04:11,150 --> 00:04:17,280

And so this was the practical or you can call a fun lab for hashing.



57

00:04:17,570 --> 00:04:23,900

Apart from that, you will never be asked to write the algorithm for all you have to do is go through



58

00:04:23,900 --> 00:04:25,940

different types of hashing algorithms.



59

00:04:26,510 --> 00:04:33,230

And if you need anything, if you need help in learning these algorithms just posted in the Onion section,



60

00:04:33,230 --> 00:04:36,520

I'd be very happy to help you out.



61

00:04:36,920 --> 00:04:37,370

All right.



62

00:04:37,640 --> 00:04:42,800

In the next lecture will again talk with some important concepts like digital signatures.



63

00:04:42,800 --> 00:04:46,090

So the authority and articles are necessary.



64

00:04:46,340 --> 00:04:47,490

So stay tuned.



65

00:04:47,750 --> 00:04:49,240

You are doing a great job.



66

00:04:49,250 --> 00:04:53,780

You're almost going to finish this wonderful section of cryptography.
