The constraints for e is just {2 < e < r; gcd(e, r) = 1}, and it has to follow those constraints so that the encryption is one-to-one rather than many-to-one, where in the latter case it would not be reversible. More recent versions of RSA use the Carmichael's function, in this case λ(n), (which simplifies to lcm(p - 1, q - 1)) in those constraints rather than r (which is just the Eurler's totient function of n). It achieves the same results but has the benefit of faster decryption.

I usually never comment on videos but you’re an absolute legend mate, you exactly know how a student thinks and you know exactly what to teach, please upload more videos, i would love to learn coding from you, cheers

@linamoussadek6467

Why doesn't this have more views??? Thank you so much !!

@Moocow2003

Thank you so much for this tutorial! I could not wrap my head around turning the concepts behind encryption into code before this.

@granger1019

Fantastic. That equation for d was what I was struggling with after a geek for geeks article. Thank you.

@rudraprasad3

Bro you have only one video and a great one.

@thegreatpugtato

Holy shit this was actually huge for an assignment, made it so much easier and less stressful

@CloudCoder-c8h

Thank you for this informative and insightful video! This was easy to understand and very helpful.

@greenxdshadow6635

Thank you, saved me about a half hour of textbook reading

@pedropago

this dude just saved my finals, awesome video thank lord i found it

@michaiahf

How does D = 7? I don't understand that part. Is 7 just a random number that you are using as the message to send?

@emmrodriguez

flawlessly explained bro! thank you

@lucinali6617

I love it! I'm looking forward to learn programming with python with your video.

@นายเยิ้มยิ้มเเย้ม

thank you for make this vdo ,
I educating form this video  to prepare myself for upcoming exam.

@SirArghPirate

I don't get it; how does 3^(-1) % 20 equal 7 and not 0.33..

@georgia9337

So helpful and informational !!!

@zachahmad4097

Really nice video....definitely simple and yet makes  a lot of sense!

@MuhammadRaza-yd6sg

congrats on 200 subs!

@Its_Me_Butters

Simple AF, come back with more stuff dude!

@Листочек-ч3к

Thank you so much! The best explanation!!!
