Now, after this, we see the logic of was once we have devalued value there, so we go now for the
check and final check is English not and English if we open up the file in notepad.
We are having here is English chick.
That's the metal that we want.
So here we use is English metal.
And in this we pass the value which is there from the cryptic text which we have got comma.
We pass here the word percentage that's equal to Pasic 40.
And in this effort, which means this particular line will check with the user to see if the decrypted
E has been found.
So here you print a blank line, the next you put in your C possible encryption break.
Then bring to the value of key plus SDR Woodvale with that concatenated again, see single code holding
single codes and the value of decrypted it that two hundred limited.
Then again, let's bring the blank line and then we give your print saying we are giving the message
to enter the four done.
Or just press and.
To
continue and let's close this year and whatever the user type, they could be using this input.
And then we check that if the response does not convert to Apple Dot.
Starts with you, you hear the case when we say the only descriptive text.
And finally, one, this is done.
We end this and we check here.
If name is equal to men, then all the men.
Now, let us save this file in the same spot when we have done all your examples.
So hacking advanced level and here will give, say, hacking, Virginia Saiful dot fever.
And now if we know, first of all, we have not given anything to be hacked.
So what we would give is first thing we will do is let us open the Virginia site for Demo Oleo.
And if we run this module, this is what is the encrypted text.
So now we will cooperate on the same thing over here and now we would run this module.
So let's save it.
One thing we made a mistake.
We have never will a state and you're just not as smart as it is, not one in which we have it means.
And the message also we would write down over your encrypted message format, 56 days X is NZ, E,
C, C, X, and if you then say Cucu, sorry, missed one more in me and let's see it.
Let us try to decrypt this particular vote.
Now, if you're not satisfied with this, we continue.
This is what we have doki astronomy and a particular textbook and using that.
So now we press the.
And so that is all we have basically hacked off can using a dictionary value.
So now if you just need to understand, whenever you run the particular values, this are just some
keywords that as we have done and if we press enter, we can get to go along with some more keywords
if it is not able to find it, if we give you an error message that unable to hack.
So now over here in this particular demo now, because the source code for this program is similar to
the previous hacking program that we have done, now, we want to be going line by line examination
because that is not required as already we have completed part of this in the earlier one.
So just a function that we have created in this program is your dictionary function, which basically
attempts to use each vote in your dictionary file to decrypt the ciphertext.
And when the decrypted text looks like an English word, according to your English module, then it
prints the decryption and it prompts the user to quit or do so over here.
If you just look at it, we have used your words.
One is equal to a four one dark red line.
So we have used red line method over here on the file object written from open.
Now, unlike the method which returns the full content of the file as a single string, the ridgelines
method returns a list of strings with each string as a single line from the fight.
So since that is one word in each line of the dictionary, the word variable contains a list of every
English word.
The rest of the program that we have over here is similar to your transposition cipher hacking one which
we have done.
So this requires absolutely no values.
It doesn't require a special understanding of the program as it is already done, all of you, to know
that we have written a program that checks your weakness for using a dictionary attack.
Now, let us look at how to have the beginning of Saiful, even when the key is a random group of letters
rather than some dictionary word in the particular case.
Now for that we will understand the concept of using the ASCII examination to find the snip.
Now, because ASCII examination is a process that we can use to determine the length of the original
key, which is used to encrypt the ciphertext.
And we can then use the frequency analysis to break each of this up.
These independent Charly's Bobridge was the first person to have broken the beginning cipher using this
process, but he never published his results.
Now his mother was later published by our friend Reg Pisarski at an early 20th century mathematician
who became the namesake of the metal.
So now let us look at the steps involved in the examination.
First is, you need to find the repeated sequences.
Now, let us understand this more in detail in the next edition.
That's it from the session.
Thank you very much.
