For making the equation equivalent to 21, we multiplied 3 to each sides.. now the eqn becomes 21*d= 3 mod 20..now 21 mod 20. Equals to 1.. so the eqn will be 1*d = 3 mod 20.. whenever the coefficient of d becomes 1 the value on the RHS side will be equal to d.. is it clear now,?
This method is so much easier than other methods... really helped me... Thank u very much
I've been looking for the best solution for days and this video suddenly popped up. Thank you for saving my exam!
Bro u just saved me more time in finding value of d bro,, Thank you so much❤
Bro what about bigger numbers like 121 and 151....?
Very nice trick
Thank you so much for this simplified method
thank youuuu , you helped me a looooottt ; i have an exame in cryptographie after tomorrow
ayo did you pass bro?
@@greenstonegecko yes i pass it
now i am seeing this video as my exam is after tmrw
@@ruzarfernandes8918 good luck bro
Is there a formula to make it easier with big numbers?
Your last step is not clearly understood. How is d= 3 where (21 x d) = 3 mod 20?

and atleast i subscribed for my first time thanks
Excellent
Make video on how to calculate e
e is a number relatively prime to fi n
Oh my god...this is so easy. Thank u bai
the genius always deserves the best blessing from God dad you rescued my mind Dad
Thank you, that was very easy and understandable
Thank you, keep supporting 😀
Bro awesome …..it was the easiest step 😍
Thank you so much
This method is not always working, try dx8 = mod 60.
What is the name of this algorithm?
Sum 1 ,
If equation will be multiple by 27
Isn't it will be 81× 27d ?
Thank you!!
Thank u sir 👍 it really helped alot...
Thanks and keep supporting
It really helped me
thank you so much,
how to solve for P=3,Q=11,E=7?
it don't work when in this example
n = 119
fi(n) 96
e = 5
thank you sir for simple explanation
thanks
Thanks keep supporting😄
Sir can you please teach how the public key (e) is calculated when private key (d) is given in the question
How to?
Thank u sooo soo much sir g
thanks a lot
Thanks u sir ❤
It is usesless for large numbers as it will consume a lot of time !
Thanks 🙏
bhai e niklana bhi batao
sir please tell 13 * d mod 60 = 1
Thank you gangy
Not really practical with big numbers.
Will be uploading another trick soon to solve it for big numbers
rsa algorithm n=221 and e=5 find d can you give me solution of this
can you please confirm if the answer is 177…
17*d=1mod 60.what is the d value
53
Thank u
dude 3 = 1 mod 60 is never ending decimal number
Please Calculate 7*d = 1 mod 60
Hi can you please find private key for P=143 and Q=11 , helps me alot....Thanks
*Not applicable for all numbers
nice one
5
you save me!
Збс, а русским как быть?!
Так все же понятно)))
Thank u
