i saw somebody commented on vir das' video, that "i have liked the video before even starting to watch".. I did the same for your video, before even starting to watch; because to me you make contents that's absolutely great and honestly nobody has even presented to me in such a way for the network security category
Sir you have helped me a lot sir during my exams time. Your explonation is very goood and clear. Keep maintian that sir. You are one of the best teacher in my study career. I was scared about this subject and i found you on youtube. Now i learned lot of subject. Thank you very much sir.
hi vasantha raj soon i will try to upload them . thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
hi mohammed thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
hi poornima thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
hi rishabh based on the plain text message we are supposed to take the matrix.if the matrix was not complete then fill with some dummy letters. and key should be numerical.
hi Mayur sure and i will try to upload it soon. thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
hi kumar you are correct in rail fence we have consider the key and based on key we need to do the transposition. i just forget to say that in the video. thanks for your observation and correction.
Sir the key should be given i think I am a makaut student in a message 'happy birthday to you"they construct it in solvation they take 2 line ..I can't understood why they take 2 lines
hi ramyasri soon i will try to upload them . thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
Thanks for the reply sir.. But I have then another question that, how they are going to decide where to put space during decryption? because we are transmitting stream that is without space?
hi Sanket Due to security issues there is no explanation regarding decryption process and i think there will be some other procedure for decryption. thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
hi Shashank May be due to security problems the decryption process for any algorithm was not explained in any material and they will give in a single line as the decryption process is reverse to encryption process. so we don't know exactly how the decryption process will be implemented.
Split cipher into two halves, write characters alternately from each half. M E M A T E O A A T (one half) E T E T H T G P R Y Recovered text is "meetmeatthetogaparty" While decrypting, if there are odd number of characters in the cipher text, write greater half as first line and smaller half as second line.
you can choose any of the order making sure to fill the whole rectangle with dummy characters also sir has explained it wrong so better refer to other source

your friends and subscribe to our channel.Keep following our channel.
sir u are amazing sir u have helped me alot in automata subject because of u i have passed the exam thankyou so much
Sir you used here 5*4 metric but you are saying for 5*5 ..kindly clear this doubt ?
Hi Sundeep, I assume that blank spaces should be added also to both of your examples?
Nicely explained
I like ur videos sir
Thank you sir...
Nice sir
What is the significance of key value in raw transposition.. result is same for any 5 digit key. 32541 or 12345 make no difference ?
Super
Thank you ❤
Why are you not explaining decryption process in the substitution and transposition method?
can u plz explain all the transpostion techniques?
Why you didn't consider the blank space in rail fence cipher?
Sir kindly explain how to decrypt the cipertext using row transposition
Wouldn,t the spaces between the words considered as a bit while converting from PT to CT?
Super sir I understood
Thank you. I have cns exam tomorrow. I am from bangalore University. Which all should you study and go?
hi poornima
thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
Thank you sir🙏🏻
Why don't u explain cryptanalysis of all these techniques
IN row transposition
If we create a 4*4 matrix and p.T is welcome to my session , then
While filling the table , all the letter how i fill?
hi rishabh
based on the plain text message we are supposed to take the matrix.if the matrix was not complete then fill with some dummy letters. and key should be numerical.
Okay
I got it
👏👏👏
Thanks Sir
sir if the plain text exceed the row no. i.e if it gets greater than the no. of digits in the key. then what should we do
Thanks a lot sir😊🙏
Sir, can you please explain "One Time Pad Cipher"?
hi Mayur
sure and i will try to upload it soon.
thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
Sir how to convert cipher Text to plain text in rail fence ciphers and row transposition cipher
cypher text : omahaseeyawaameyaala
Ty sir
Tq sir
sir,in rail fence cipher no of lines depend upon the key value but sir you do not mesane any key and you can draw one line why?
hi kumar
you are correct in rail fence we have consider the key and based on key we need to do the transposition. i just forget to say that in the video.
thanks for your observation and correction.
Sir the key should be given i think I am a makaut student in a message 'happy birthday to you"they construct it in solvation they take 2 line ..I can't understood why they take 2 lines
How we can do Row transposition with the help of two key?please explain.
Can u explain monoalphabetic technique?
Sir, You are awesome!
Sir can u plz explain polyalphabetic cipher&one time padding
Thank you sir
Plzz do a video on security mechanisms sir i need it it is helpful for me
hi ramyasri
soon i will try to upload them .
thanks for your interest towards our channel and share my sessions with your friends and subscribe to our channel.Keep following our channel.
please sir decryption method bhi bata diya kro
How to decrypt row transposition cipher?
Pls simple columnar, vernam, book cipher
Pleased with your teaching sir, pls make videos on RDBMS and Data Mining
Dear sir, Why you are not considering space character in plain text during encryption?
hi sanket
as this is transposition technique we should not consider the space as a character.
Thanks for the reply sir.. But I have then another question that, how they are going to decide where to put space during decryption? because we are transmitting stream that is without space?
hi Sanket
Due to security issues there is no explanation regarding decryption process and i think there will be some other procedure for decryption.
thanks for your interest towards our channel and share my sessions with

thanks sir. Will definitely share your videos.
Sir... in playfair...table.. can we take any other letters like pq or lm ... instead of I/J in a cell????
Only i j
Sir how to revert thease msg?i mean ct to pt from these two methods?
Thnx sir😍😍
sir in rail fence cipher how to get back plain text from cipher text
hi Shashank
May be due to security problems the decryption process for any algorithm was not explained in any material and they will give in a single line as the decryption process is reverse to encryption process. so we don't know exactly how the decryption process will be implemented.
Split cipher into two halves, write characters alternately from each half.
M E M A T E O A A T (one half)
E T E T H T G P R Y Recovered text is "meetmeatthetogaparty"
While decrypting, if there are odd number of characters in the cipher text, write greater half as first line and smaller half as second line.
This is columnar transposition..nt row
hi Nijjar
you are correct and i agree with you thanks for your observation and correction.
then how to decrypt the cipher text?
Sir why did you choose key only 32451? Is it rule?
you can choose any of the order making sure to fill the whole rectangle with dummy characters
also sir has explained it wrong so better refer to other source
Sir plz ak video compiler me b bnaeye.
sure suraj definitely i will try to upload.
Thnku sir
Pls provide the mcq in this concept i.e network security sir
can u upload video of iot(internet of think )ty computer science

thanks a lot becouse i got great knw from your video
What a out key in rail fence copher
I think it is columnar cipher... Not row cipher
here key used is 2........................................................
nice sir
