All right, so here you can see that I'm on this website, Tools for new Starcom, I know this website
name is very funny, but apparently that's the best hashing tool do right now.
So let's calculate the hash.
Let's start with MI five, which we have seen.
So let's say I want to write.
I love cyber.
Security.
All right, I love cyber security, not that I have.
You know, what I've written is Somalia.
It's Lorqess.
And now let's see, I hash this, OK?
You can see this is the hash resiled.
OK, this is the hash.
What is it?
Just keep in mind about this has risen because we are going to need it.
One F seven C five.
One five.
You have to remember this all.
You can shoot it down.
I love it for a couple of seconds.
All right, now what I do is separate cyber and security and now let us see if the hash value changes.
Of course, it has changed, you can see it has changed, the hash value has changed.
So if you see this hash value you.
One five seventy five, and if I give a speech are right here, the hash value is completely changed.
So this is the hash.
So even if you change one single bit, the entire value is going to change.
OK.
Another to say, I write, I want.
To loan.
Cryptography, I won't learn cryptography now you can see this hash value the length of this hash value,
there is not as a two as the two.
So you can see these are the number of hash.
Who Ghadames.
Let's go to a set of two, which is two fifty six.
And let's hash this.
Just see the hash.
OK, just see the length of this hash.
All I do is again I write I and again I'll hash this.
It's going to change, right, and even let's see, I copy all this and irrespective of my input, irrespective
of my input, the length of the input output is going to remain the same length.
This is one of the most important properties of hash that irrespective of whatever length of input you
give, the hash output is always going to be a fixed length.
So as you can see, even if I remember this, even if I remove this, I'm sorry, the hash is going
to teach.
So this is how.
Attackers, you know, carry out hashish and now you might ask a question, if you already have MI5
in place, why do I need a city to physics?
Well, even attackers can have a brute force attack and find out both attacks.
But the more and the greater the length of the hash, the greater the size of the Indian got them,
the more it gets difficult to crack the hatch.
And as such, it is almost impossible to crack because no one has yet cracked a city to look at them.
You're not going to dive deep into the algorithm because it's a lot of technical and mathematical.
And since the scores is for people who want to get an overview of information security, I suggest that
this is more than enough.
All right.
And so this was the practical or you can call a fun lab for hashing.
Apart from that, you will never be asked to write the algorithm for all you have to do is go through
different types of hashing algorithms.
And if you need anything, if you need help in learning these algorithms just posted in the Onion section,
I'd be very happy to help you out.
All right.
In the next lecture will again talk with some important concepts like digital signatures.
So the authority and articles are necessary.
So stay tuned.
You are doing a great job.
You're almost going to finish this wonderful section of cryptography.
