Show why the college in part.
I hope that you remember what Sha one is it is a very popular hash function that we use today of course
we have.
Five hours away.
That is not recommended by a well show.
While on this very popular hour.
I want to let you know that Google published documents showing two different to PBS with the same hash.
The ADL for shyam D5 aren't all other functions like this is to make sure that you can not really modify
a document of fire.
And then you just to create a hash and comp and you know okay this is what I create then nobody could
change their documented this fire because this hash matches.
So I want to show you slide just in case you.
It's been awhile since you since you learned about shine them D5.
So the idea is that we get to documents who can see their red and the green one and then we run chamois
and then we get it's just a hash tag.
Please know that.
It's huge.
It's not even close to the red one.
When you compare these Hashi's and this is a really good because even if you make a small change you
should get a new hatch.
What Google would Google did was they took two different PDA documents they ran.
Show why.
And yes they were able to get their same harsh it is called a coalition.
And this is really bad because in theory it means that I can do the following thing.
I can say saying JENNY MAY are saying you owe me 1000 dollars and then I can modify it like Vaise.
What's more I can Iran.
Siobhan Yeah well you all think that's whether it has modified this file since it was created.
Of course it is not that easy even when you analyze this document that was published by Google.
But this is what you can achieve when you find a collision.
It's just a matter of time.
Dad was see more and more Taus allowing you to take advantage of this new feature of this new coalition
that was this car.
In a way published by Google.
Yes I think it is time to move to shut to or shut three.
