QHWZRUN VHFXULWB = NETWORK SECURITY WELL EXPLAINED THANK U SIR , DAY AFTER TOMORROW IS MY COMPUTER PROJECT AND THE TOPIC IS ABOUT CAESAR CIPHERING . TQS A LOT SIR.
By default it's 3 but in our university exam they made the last digit of our roll numbers the shift key... So 3 IS THE DEFAULT KEY, you'll be using that
the math is: Encryption: C = (p + k) mod 26 Decryption: p = (C - k) mod 26 Where C is ciphertext, p is plaintext, using the alphabet indexed from 0-25, and k is the shift. For a Caesar Cipher by definition/default the shift is 3. k is easily derived from the decryption equation, but given that it's mod 26 there's only 25 possibilities so it's easy to brute force. This should be trivially easy to convert to code. I don't write C#
sir there is one wrong value in encryption which is 'm', the encryption of 'm' is 's'.....not 'p' like that c=(p+k) mod 26 =(15+3) mod 26 =18 mod 26 =18 =s
Thank you so much. This video really helped me understand the calculation!
Crystal clear, neso academy is best. not any "n min engineering" can replace it😁
What?
@@maxius7119 its 5 minutes engineering
well explained the h.w is "network security" did took me a whole min to decrypt
Thank you Subramanian garu very EXPLAINATORY and Easy to understand 🙏 for work 👍
Nice explanation the homework answer is NERWORKSECURITY
NETWORKSECURITY
Great presentation
(-2) mod 26 = 26 - 2 = 24 -> Y The plaintext is NETWORK SECURITY
network security
Thanks
-3 not -2
thanks so much and good explantion
Network security I was dozing at first and i felt like I won't get it until I read the comments saying u explained very well phew😅 thanks I understand
Home. Work answer:-(decript) network security

Awesome! You made it clear for me. I have just subscribed to this channel!!!
excellent explanation. I've been following your videos and they make things really easy to understand. well done!
network security
is the answer
thank you neso❤
Please uplaod all the chapters as early as possible ... We just depend on your playlist ...
Thanks sir it is really helpful to me

WELL EXPLAINED THANK U SIR , DAY AFTER TOMORROW IS MY COMPUTER PROJECT AND THE TOPIC IS ABOUT CAESAR CIPHERING .
TQS A LOT SIR.
This explanation is perfect! You really helped me. Thank you so much💕💕
So helpful here
You’re home assignment is NETWORK SECURITY
Thank q. Sooooooo much this was my exam and u made u understand perfectly💯
Thank you very much 💕💕
very helpful
I really love the explaination in the network security
Great explanation!!
Thank you very much!
The plainText is Network Security
Wow great explanation…
Thank you so much mam
thanks!! for my test thursday :DD
Thanks sir! useful video !
thank you so much sir. This video really helped me
Thank you for explaining better
Sensational video.
Thank you very much, you are the best
Thank you so much sir!! U saved me
Good job
This is honestly so easy now. Thank you so much.
Upload all the chapters ASAP because this subject is there in my current sem and i only depend on ur lectures...

Thank u so much 😊
nice bro i can understand easily....

I agree, i got the same!

NETWORK SECURITY😊😊
Thank Neso Academy for this class, I have understood.
keep teaching that way
Convenient that nesoacademy has a y at the end to demonstrate the mod26 in action haha
Nice understood
good stuff thanks
PLEASE UPLOAD ALL CHAPTERS AS SOON AS POSSIBLE
Tqsm for this masterpiece!
Thank you
NESO ACADEMY THE BEST
Shift key=3 is fixed or it can be changed for some speacial condition???
By default it's 3 but in our university exam they made the last digit of our roll numbers the shift key... So 3 IS THE DEFAULT KEY, you'll be using that
thank you sir the answer is network security
THANKKK YOUUU
What app did u use sir ?
How do we decipher if there's no key given for Caeser Cipher??
Thank you so very much!!! This is more than helpful.
Sir kindly make the video on DES algorithm and 3DES
After decryption , the plaintext is networksecurity
We need more please !
If you can provide us codes for encryption using c# , we'll be grateful for u !!!
bimbo , if you cant code this , you better learn basic programming first
the math is:
Encryption: C = (p + k) mod 26
Decryption: p = (C - k) mod 26
Where C is ciphertext, p is plaintext, using the alphabet indexed from 0-25, and k is the shift. For a Caesar Cipher by definition/default the shift is 3. k is easily derived from the decryption equation, but given that it's mod 26 there's only 25 possibilities so it's easy to brute force.
This should be trivially easy to convert to code. I don't write C#
what is the reason to divide with 0 and at last u divided it with 1 .I want to know the reason sir🥰
Network Security 👍🏼
The answer for the Homework part is NETWORK SECURITY
i just did it too and got same
@@doatanu I thought everyone gets different answer
@@ajgaming2yearsago194 😂
Same revers for encryption
Sorry I don’t get it u are
You are using 25 in 26 mod
Can it be correct?
Please explain for me
please add subtitles, thank you!
Network security was the answer and btw the explanation is so DPDCLQJ !!!!
you said, AMAZING. [23]

MY HERO
Answer to H.W. : network security
sir how do you find the value of k? is it constat that the value of k is always 3?
if in answer the value for key will not be given in that case we will take the key value as 3.
Network Security!
NETWORK SECURITY - homework
Thanks to NA i need to know the de cryption this time.
Come here to learn about it…. Just for journal three book… great
Network security🔒
In Ceaser cipher always the key value is 3 ?
no their will be diff keys its all depends on the question or u can mention there which key u have taken
network security is the ans for homework
The plain text is Network security
Plaintext : NETWORK SECURITY
Nicee
sir there is one wrong value in encryption which is 'm', the encryption of 'm' is 's'.....not 'p'
like that
c=(p+k) mod 26
=(15+3) mod 26
=18 mod 26
=18
=s
Love the accent
Network Security- Answer
for the last encrypted digit B having index 1. how do we decrypt it (1 - 3) = -2 ??how do we doo that
(1-3)mod26 = -2 + 26= 24 which is 'y'
Add 26 to -2. You will get the answer 24 ---> Y
x-a , y-b , z-c for quick answer for only these 3 alphabet
ans is : network security
Decryption -= NETWORK SECURITY
NETWORK SECURITY is the homework answer and I used Caesar cipher wheel
Decrypted text is "network security”
Plain Text Is Network Security
Tamil Nadu?
thankkkkkssss'
❤️❤️❤️❤️❤️❤️
decrypted text is ---> "NETWORK SECURITY"
decryption of 'QHWZRUN VHFXULWB" = "NETWORK SECURITY"
How do you write z= w
