Now, in this session, we will be using the brute force approach to hack the transposition cipher of
the thousands of keys that could possibly be associated with the transposition cipher.
Now, the correct key now should be the only one that results in an eligible English.
So here in this particular example, we would be using the older example which we have created for Czech
English.
OK, where we have written transposition cipher Hackl program will find us the correct key using the
Czech English not be code or that we have written.
So now let us come and write down this old score for the Transpositions Saiful Hackl program.
So as normal we would be creating a file new file and we would be entering the code here and saving
it by any example, not by.
OK, now make sure wherever you are saving this particular fight in the same folder, you should have
the paper clip.
But also you should also have the Demo 13 file.
Also check English that we have seen.
Now, if you just go to your Windows Explorer here and look at our folder, that despite an intermediate
level here, we have the checking list or pivo, which we have already done now Demo 13 and we have
taken from our beginner level because in that we had created for decryption and the paper clip we had
imported.
And this dictionary is indeed from the last station that we have created.
So all these four files have to be there in the same folder where we want to see if the current file
that we're creating.
OK, so now let's go back here and create a file for transposition cipher Hakka program.
So the first thing we will do is write down here the import paper clip.
Then the next we have is check English
and the next we have this demo 13.
OK, now we define here the main method.
OK, now in this particular code, we would be writing down your message saying, my MSJ, that's equal
to OK, we are giving it in quotation marks.
OK, now here, before writing this message for decryption, what we would do is let us open.
Now in drive, we have this Demo 10, which is basically for encrypting.
So here we would put some text, say this is 510
hacking
intermediate level because we are trying
hacking with Trons position.
Sipho.
This message is used to.
Encrypted the text now we have written this particular message, let us splattered across multiple lines.
And.
Let's try to give your.
OK, and now let us try to run this particular course.
Now, this is what we are getting it as an encrypted message, so now we would copied on this.
OK, let's close this demo then.
As for now and here, we would paste that encrypted, which we want to decrypt using transposition,
hacking.
OK, so now if you just look at over them online, for example, Lemington, for example, we have Yoshiaki,
that is.
And this is the text that we have used.
OK, so now the same key would be used for decryption.
So once we are done doing this particular or executor's particular program now, what do we want to
do is if we want can move it like this.
OK.
And then after writing this, my message board here, let's not give these basis, let it be hazardous.
OK, now, before below this, we would have had a misty start.
Now that is equal to we are going to find another matter in this and that matter will be be transposition.
So we are calling that over here.
Haak trons position is to give their mind MSG's but amica would you want to.
Hecate OK then we check if we had Misty GST are is equal to none then we are going to give here princi
in single quotes say field.
To crack encryption or else we will give print as.
Copying her message to Clybourn.
OK, and we know that we will give another predicament where we would be printing the hacked Amnesty
Aschiana message and then we would see a paper clip not copy again, hacked Amnesty Hestia, OK.
And after this now we are supposed to define the hack Tranz position, SDR method, which is going to
be a message Asgeir as the not going into it.
And in this particular message or the method we are going to print, say, in single code hacking.
OK, close this then.
Now over here, basically Python programs that we're executing can be stopped at any time while executing
repressing controls on windows or control on machoism Linux.
OK, so here we are going to give a print command for the user leaving their text, say press control,
see on windows or control the say on Mac OS and Linux to which at any time when the program is executing.
Now after that, we would be using a brute force by looping through every possible key.
So we use here the key is still in the range of we are giving one comma the length of messages here
and in this four loop we are printing C trying keep hash, we print your percent s, then we give the
end of single code and print the value of SDR here.
Then we use C decrypt or decrypted text SDR.
That's equal to now.
We want to use the demo.
Then don't let us just open up the demo then file.
Let's open demo 30 and here we are having the decrypted messages here.
So we would be using demo 13.
Bot Decrypt message is still here.
We are passing the GST R and the message STF wanted to create the method again.
Hence we are using it for.
