kudos ! wrapped under some minutes ! also M is not number of digits Its is decimal representation of string message. (Cryptography and NS by w stalling)
The calculation for 'd' doesen't work if we have large values for n, and phi of n, As it just becomes a Brute Forcing by counting each mod upto idk a thousand before until we get the correct value of 'n' Thats basically what my instructor replied with
For mod if u are do example 7mod3 First do 7/3=2.33333.. Then do 2.333-2=0.33333.. Then multiply it with the rhs i.e 3 You will get 1 Do the same for your problem
can you tell me what are the key distribution approaches for method authentication in cyber security ? i have exam.. is it the same you are explaining ? symmetric and asymmetric any other approches?
Your explanation of algorithm is good!. But, the question every learner should ask is how is decryption key sent over the internet to the receiver so that he can decrypt and read the message ? All i say is just don't blindly understand the algorithm without knowing the use of it.
GCD of 2 numbers = 1 means they are co-prime. GCD OF 20 AND 6 is not 1. Greatest common divider of 20 and 6 is 2. .... you said we can use 6, coz 6 is not a factor of 20. You are confusing factor with GCD. LOL 3:40 "YOU CANNOT TAKE 4 correct, coz gcd of 4 and 20 is 4, you cannot take 5 correct coz gcd of 5 and 20 is 5, you can take 6 LMAO, NO YOU CAN'T TAKE 6, coz although GCD OF 6 AND 20 IS NOT 6 (like 4 and 5 prev), it still is 2, AND 2 IS NOT EQUAL TO 1.
Your explanations are better than guides and notes .Thank you so much mam.
Thanks a lottttttttt 🙏🙏 You have taught so much in exam point of view ,, I have learned everything from you and wrote the exam thanks a lottttttttt
4:38 ed/mod pie(n)=1 this is how it should be right
we know that 1 mod(n) = 1/1 mod(n) OR 1 mod(n)=(1 mod(n))^-1 == 1 , thus ed= 1 mod pi(n) OR ed = 1/1 mod pi(n) , as a result ed mod pi(n) = 1
bro just consider e^-1(fi(n)) as an entity and move it to the other side , that was a mistake from the video
your notes are very clear and easy to understand. And the way you teach is fabulous ☺️💯💫

very nice explanation and it's very easy to understand for only single time.......
Its osm😁😁😁
Thanks for helping 🙂🙂
You’re welcome
Your way of explaining is too good
Thanks a lot
That is awesome series of Cryptography thank you
Madam, thanks a lot for ur kind clear explanation.....AthmaRam
How you taken Ed=1modΦ(n) as Ed modΦ(n)=1
how?
@@raomubashir3976 actually the formula is edmod(n)=1,she took wrong in video
@@VijayKumar-hn2hx right but now it's too late to talk about this , cuz i gave its paper yesterday 😅
@@raomubashir3976 🤣ok
Ed=1modn means edmodn=1
That is ed divides by n then get remainder is one
Best video i watched so far for this topic. Thank you
Excellently teaching mam and like ur flow of speaking and understood very well mam thank you very much
Time complexity and space complexity of RSA algorithm, where this algorithm is used
The calculation for 'd' doesen't work if we have large values for n, and phi of n, As it just becomes a Brute Forcing by counting each mod upto idk a thousand before until we get the correct value of 'n' Thats basically what my instructor replied with
Thank you...well defined class lecture with simple communication
1:50, those two numbers must be prime numbers
Your explanation way is very good to understand 🎉
very explicit thanks
ed=mod pie(n)
edmod pie(n)=1
?
?
Extended Euclidean algorithm
Ma'am, lectures are so nice. Please guide how can I get these notes?
Any tricks there ..to find d value faster
d=(∅n + 1)/e
We can easily find
Hi
Thankyou so much ma'am. All my doubts are getting cleared a day before exam :)
Superb Explaination 🔥🔥🔥
hlo mam u have explained the things so easily and it was very helpfull to me mam and so for that thank you mam.
Most welcome 😊
Love you for your explanation ❤️😇😘
Hmmm
Wow so easily u explained 👏👏👍
We have to take 2 prime numbers in the starting.
ohh maam what a cool way of explaining
Thaks a lot sister u helped me a lot for exam .
Tqsm ❤️u
Tanks a lot ma'am
U clear all my doubts 🥰🥰
p and q are large primes for better security
You are taking so clear
3:42 gcd of 20 and 6 is 2 so you can't take 6
P and Q should be prime ..pin
4:24 how did mod⌀(n) come to LHS?
same question
how did you calculate the huge cipher text value on a calculator and how did you do mod and all that stuff?
For mod if u are do example 7mod3
First do 7/3=2.33333..
Then do 2.333-2=0.33333..
Then multiply it with the rhs i.e 3
You will get 1
Do the same for your problem
@AmmaraIqbal-y9e thanks I actually figured this out on my and my exam's already done.
Thanks anyway ❤
How do we calculate 31 power 7 mod 33? Plz help me
Thanks for your explanation
Could you please explain how to implement it practically
don't understand at the time 4:25 .. plz tell me in deep
how do we assume m in this case?
by hit and trial?
won't it take a lot of time and calculations?
Any value works which satisfies the condition
Thanks a lot
your way of explaining is too good
Thanks a lot
Thank you it's very clear
good explanation
I love your voice mam ❤❤
can you tell me what are the key distribution approaches for method authentication in cyber security ? i have exam.. is it the same you are explaining ? symmetric and asymmetric any other approches?
Your explanation is super mam🫂🫂🫂
why edmod(fi(n))=1?
Explanation is good but there is no theory about the concept in video please include it in future videos
Nice explanation
Add Chinese remainder theorem in the cns playlists
How to calculate 31 power 7mod 33 c=4 ?please suggest me
Calculator
Should p and q be prime or co prime or not?
prime
Simple and easy ❤
how to do MITM in cryptool ???.. please make video on it!!.?
U first wrote d=e^-1modphy(n)
But by sub e=-1
Phy(n)=20
We get d =140
how did she get c=4
❤❤ thank you so much
Your explanation of algorithm is good!. But, the question every learner should ask is how is decryption key sent over the internet to the receiver so that he can decrypt and read the message ? All i say is just don't blindly understand the algorithm without knowing the use of it.
Can you please explain elliptic curve cryptography
great video
Hi madam. I have watched yours FLAT subject videos. I have passed that subject.
What is gcd here?
Tank you mam for your good explanation
thanks for helping us sis...it's very useful for us..
How to calculate GCD?
mam as you said in previous videos block cipher is symetric but here you said RSA is block cipher so it must be symetric but why RSA is asymetric
Can u please share the vedio of fermats & Euler's theorem in CNS by tomorrow
Is that prime large number or only large number youu have not given clarity mam can u tell
thank u mam,that's so helpfull
How e is 7 even 3 also have gcd will come as one
Can we choose m=2 ,In encryption ?
Nice mam but I have some doubts
whether it is prime or not explain??
Yes, prime
Plz complete the playlist soon
can u tell how to calculate mod in calc
you told that you wll say they are prime or not at the end of the video, but you didn't said??
Very much useful. 🥲
u need to explain how to do calculator, like us we don't know how to do in calculator
agar yeh que 29 ka aata h or isme encryption or decryption galat ho baaki D tak shi to kitne number milege?
Thank you ma'am 👍
whether the value of encryption and decryption can be same
how to find gcd vole (20,e)
It is large prime numbers in the beginning of the video.
can you make a video how to slove large power number in scienctific calculator like 234^2345
i think it is not possible to solve using scientific calculator
How I calculate modular in calculator
I think all are using same example only
What is trick for taking e value medam
If we take any values of the M value the answer will be same ....... If not same the answer will be wrong....
actually d is congurent not equal
GCD of 2 numbers = 1 means they are co-prime. GCD OF 20 AND 6 is not 1. Greatest common divider of 20 and 6 is 2. .... you said we can use 6, coz 6 is not a factor of 20.

How you let the value 31
Mam what about 'RC5' algorithm?
Who will say what is GCd means ?
what to write sha 512 for me tomorrow exam'
How is c=4??
thank you so much sister
encrypt the word "retaliate" and then decrypt it madam
how to do mod in the calculator
31 power 7 how did u do mod in calculator
Example- 34mod 33
Do
1) 34 divided by 33 . Remainder =1 is the answer.
34mod33=1
Please note. Private key in RSA is only d not d, n
