RSA Algorithm - How does it work? - I'll PROVE it with an Example! -- Cryptography - Practical TLS

This is a fantastic video, thank you!

You sure deserve an award, sir!

You are indeed a gifted instructor! Thank you for such an amazing lucid explanation.

Great video. thanks a lot. However I've a question: Public Key will be sent to the other peer, while Private Key will be kept on sender. But once E is sent on the other side, how it knows the N, to do the encryption? He must receive both the E and N, to do the encryption. Right?

nice video but the title is misleading. This is not what a proof is

$number = 1909
$range = 1..[math]::Sqrt($number)
$factors = @()

foreach ($i in $range) {
if ($number % $i -eq 0) {
$factors += $i
$pair = $number / $i
if ($pair -ne $i) {
$factors += $pair
}
}
}

$factors = $factors | Sort-Object
Write-Output ("Factors of " + $number + ": " + ($factors -join ', ')) , it takes no time with this code, faster than blincking an eye

You're doing a fantastic job! I have a quick question: I have a SafePal wallet with USDT, and I have the seed phrase. (tag suit turtle raccoon orange fever main skull special hungry crystal mixture). What's the best way to send them to Binance?

Pretty sure E doesn’t need to be prime itself, just needs to be coprime with r

86 ????????

I ment you have jumped from 5 to 29 and you didn’t show us in the calculator how did you get the 86 ? You know we don’t we are learning you should slow done and explain in details 60 power 29 then what did you do ?

Too fast you did not work with 5 ! And jump on to 39 ! What is a reason for that ? Also when we rised the message to E you didn’t show us how did you get 86 ? Please don’t speed and explain in details

Bravo! I thought I will never understand this topic!

This is fascinating! I have watched a few of your videos and I'm completely blown away by your ability to explain these concepts. Keep it up!

this video is so amazing（づ￣3￣）づ╭❤～（づ￣3￣）づ╭❤～

this video and the content, as all of the content of this topic, is mind blowing !! so well explained with great examples, i learnt a lot today!! big thank you for all of this!!

thanks alot sir for clearing the concept with easy steps....... once again thanks alot

Excellent video. I was goofing off creating keys and encrypting short messages and found that the message value cannot exceed the product PQ. The values quickly cause overflows in Windows Calculator, does anyone recommend an app for manipulating this many significant digits?

Great video, however you haven't really proven, in the mathematical sense, that RSA works for all inputs, just for your specific input. I'm sure it's been proven, and maybe there are many proofs, but this was just an exercise to show that it works with the number 60.

hey man i just wanted to say a big thank you, i found this video from a reddit post, i was so close to leaving this topic off from my notes because i didnt understand it but im glad i didnt, thanks again and now im off to watch your DH video

Best explanation I've ever seen of RSA. Outstanding job!

Ur great 🎉

smooth explaining, thank you

Do every pairs of prime numbers create semi-prime number?

Better video than That British Asian dude.

Great video, thanks. How is it like today with AI? Are today's models able to defactor really big semi-prime numbers easily? How does it affect cryptography in general?

thanks it is so clear.

This is an awesome session of understanding RSA with a working example.

very cool video, thank you for explaining with math !

great

Please please keep teaching you are really making differences in peoples life. I would love to meet you in person and/or help/contribute in anyway possible.

thank you very much

Wow Ed makes it so clear and easy to understand.

Thank you so much!

Hamill Pine

U talk about technology like a fascinating story, perfect explanation, thank u

You're such a great instructor.

Amazing explanation, so easy to understand.

You are the best tutor I have ever seen

nice video keep it up

21 * 21 has factor of 21, 21*21 it's not semi prime

But if someone managed to get the public key wouldn’t they can decrypt all cipher tex?

wow you are a great teacher...later of a few videos finally I can understand 😂
