Hello, welcome.
In the previous lesson, we used static analysis to try to make educated guesses on the algorithm for
creating zero key.
So to confirm it, we are now going to use a debugger for the dynamic analysis.
So a good place to put our bitcoin is probably over here or here.
So we put our break point by pressing F2 and then we run.
Make sure you look local in those iboga selected click on.
Right.
Caitlyn, yes.
OK, so now he's asking for your name, address, put hee hee hee hee, and for this year, he's going
to press the series of and check.
And he sells Bitcoin, so now we're going to analyze these memory over here, as well as the register
to see what happens when you start using effort.
So now we are here.
Let's press Effi.
And now he's going to name the suspects and no, we're not sure.
So now instead, step where we are now here, and he's going to push the address, the name is, which
is his address here.
So you can actually go to this address by going down here, Tongji, and then go to the address your
ex for that one.
He have a four for one, a have a four four.
So now we're here at a moment.
This memory is empty.
So now once you get that item takes issue, populate this with your name.
That is how hypothesis is now going to push this to this state.
So let's have it.
And now he's pushing to save money for four by the day, waiting for it, and then you're going to step
over step.
And now he's going to call.
After this call, this is going to populate this fourth parameter district parameter.
We want it from the input box so we assume is going to be the name.
Now, you can refer to it as the Google Right index.
Now, this is the index that the parameter is string.
And it took burm, according to the documentation he's about to receive the text, so we are right.
So this is where he's going to start idea Nimoy's silkie.
So we shall find out after we step with this.
So what happens in this address forfour, which contains the string?
And you see it here.
This is why we entered for the name, so we were right.
We were right in renaming this label as names.
Now, this confirms our suspicions.
That means this is we are also correct.
This should be the key.
So now have already got our name there.
Let's go continue to go through the second gate tonight, and we should be reading in the key from the
input box, which is here, Nikki.
So let's step over this effort.
OK, so now he has loaded the address and the radio, the string, which is going to store the key.
So he actually contain this address for storing the key this year key, which we enter so we can go
right now, one eight F, nine C for one.
You have 94 come down here.
That G and key in the new address, zero x one eight F, nine C four, which is the current X value
click.
OK, and now we are here.
Nothing yet.
So we are going to step through this one much my appointments and see if anything comes in here.
We are expecting it all.
Yes.
Which is why we entered.
And true enough, we get less.
So this, again, confirms that this key you correctly labor religious variable is key.
OK, next is going to get your local time.
And local time and is good new the city, too, so local time, let's tackle this now.
He continues to do so to this Denise.
Today, starting today, is the day of the job.
This is Chafin Hecks, so if you convert this to decimal, you should be 18.
So to this day, 18 of June.
So this is correct.
No, continue this tambour.
Steroids, and now the money is being moved to yes, the money's June six, so he's got.
So, you know, there is pushing all this to this day.
As we go right next, he's going to get a year to get this 75, so 75 X is two zero to one in decimal.
So the to zero to one.
Correct.
Now he's going to get one, two, three, four to the year.
And I guess you see me seven, so, so and so thanks for the sum of two to one plus one, two, three,
four.
So is adding your year to 104 and getting this result hex?
And he's going to push that to the states where.
And now it's going to look your name, so.
So after loading the name to the X. So this is your name?
Now he's going to push it to the states level, so why on this particular state and then it's going
to be upholstering as well, which is going to push to the state.
But before that, he's got a lot of us.
So a lot to ex, right.
So now he Texas called the upholstering.
So you're going to follow this in your memory.
So remember, this is upholstering is going to take all this data game on here and add in a year to
the one, two, three, four, as well as your name is going to take all those things and do something
with it and store the result in output stream.
So it's a good idea to follow this upholstering in memory.
So currently upholstering is now being calculated.
And Shawnees.
Yes.
So if you follow this address so that you can see the upholstering so one it have a Xeroform come down
to the memory here, press G to go to this address.
So key in this address, Eurex one eight at a zero four click.
OK, so you're not going to wait here and see what is going to be the calculator silkie.
So we are going to step through all this push, push, push and let's call this Grynet.
All this pushes here for this Binet.
So let's have it now and then have it again.
Have it in and take a look.
You see that the upholstering is now showing a dash, three, two, five, five, six, one, it so
noticed a pattern.
It is indeed coming from you is coming from the Navy Center then as a dash there because of the forest
fire.
So the first percentage is for the name, which is a second is a dash, which is appearing here and
in the third one.
Here is this tree to Phi Phi Phi Phi is to some of the year plus one, two, three, four.
Over here, the year is two zero two one two zero two one plus one, two, three, four.
Gives you three two five five four by six.
The sixth is this one is your Munt and then followed by one hit to this date, the 18th of June.
OK, so we know the algorithm now on how this Hiroki is being calculated.
So the rest of this is merely to compare.
As you can see here, there's some comparisons we make.
And then finally, he comes here to say that he's is right or wrong, so not knowing this, we can actually
rent a Legion kitchen.
So for that we do in the next lesson, we are going to use Biton to create Guijin.
