[@johnathonbatz662]

the mailbox analogy of everyone knowin the address of the mailbox being the public key, and only the mailbox owner with the keys to his own mailbox as the private key, is a really really really well done analogy. probably the best one ive seen so far with relating public/private keys as a concept to everyday life and making it easier to understand.

[@mjk012579]

Very clear and straightforward. I’ve been beating myself over the head with this topic in my fundamentals class and this just made the differences make a whole lot more sense

[@justArandomfellar]

same

[@tadeob_UB]

likewise

[@ender5023]

Same! This totally makes sense to me now!

[@SannySinghs]

LoL 221b BakerStreet . I have been trying to understand Asymmetric encryption concept for nearly 3 hours. None of the clips i watch explained as clearly as you do about exchanging public key. Well done. Thank you so much

[@simplyexplained]

You're the first one who noticed the address! Thanks for the kind words ;)

[@JonathanCoffey1087]

Same here, this idea helped me a little. Since most of these videos keep mentioning TONS of keys, why not use a lock analogy? We generate a key pair, one public and one private. Think of the public key as the unique "lock" you've just made. You can give that lock to as many friends as you want. If you send me your lock, I can put anything in a box and put your lock on it. Once secured with your custom lock, I can no longer open or see the contents of that box without your key that's paired with that lock.

[@juancamilo1370]

everyone talks about keys here and there but nobody mention the interchange step... good explanation!

[@teddyboggs1851]

As an American I can honestly say 221 baker is literally the only address I know in that entire country.

[@kairollmann]

And the next important thing to understand is: Asymmetric encryption algorithms take WAY longer than symmetric encryption algorithms. So people 1) use symmetric encryption to encrypt LARGE amounts of data / files, 2) encrypt the symmetric key with asymmetric encryption and 3) send that (asymmetrically) encrypted symmetric key together with the (symmetrically) encrypted file.

[@simplyexplained]

+Kai Rollmann jep, 100% true. Should've added that to the video.

[@Markd315]

And after that, probably how RSA can also be used to sign and verify data integrity.

[@lallu1122]

I never thought about it! Great!!

[@sivasankarclouddeveloper1114]

Thank you Kai Rollmann

[@uayfb1]

I believe that is how Pretty Good Privacy works.

[@scienceblossom6197]

It used to be super complicated for me but even watching this awesome video up to 02:16 helped me understand how public/private keys work in general and now it makes TOTAL sense. THANKS!

[@alvfig]

Great introduction, even for non-technical people. Thanks a lot! I'd love if you could make a similar video to digital signature.

[@ACEofMCB]

Awesome explanation and graphics for a visual understanding. I was looking for something simple to show friends and family and you've covered it better than I ever could, thank you!

[@aditi3112]

Wow..how clearly & beautifully explained. From a long -long time, I was highly confused why 2 keys in asymmetric encryption...never been able to understand...but your explanation made it clear completely. Tons of thanks to you :)

[@OHTV2016]

Excellent video, I’ve been watching many videos about this topic and you’re the only one who I actually understood from. Wonderful Job ❤️

[@falmanna]

Very nice and clear presentation

The key words here I was really looking for since a while are: "...algorithm will generate a public and private key that are mathematically linked to each othere. Public keys can be used to encrypt data and only the matching private key can be used to decrypt it.".

[@futuresocieties.]

High levels of security with mathematics.

[@JayLim-bn9fh]

Holy lil fuck! Thanks!

[@TheGadgetwiz]

This kind of irritated me because this was the reason I was watching the video. I wanted to know HOW that part worked. I already knew all the other pieces.

[@penguin-tc1cx]

@@TheGadgetwiz this channel and video is called "simply explained" for a reason... if you want to learn the more complex process behind it, you should do research or watch other videos. don't complain lmao

[@drabberfrog]

This is the first time I actually understood this after watching many videos about it. Thx

[@supadupaforever]

Thanks for keeping it simple, yet intriguingly educational for a layman curious as to how this technology works in the World Wide Web. Much appreciated sir!

[@marriagedance8657]

You deserve so much more subscribers.. Hats off

[@RM_1964]

Man you explained it in so much simple manner. I don't even need to note it anywhere. It was like a story that's in my head. Thanks a lot sir.

[@lakerfan4life308]

Excellent explanation on asymmetric encryption. I was uncertain on how could the encryption of locking/unlocking the data worked since the private key never crossed the wire. You introduced and delivered that difficult concept in an easy relatable manner. Thank you for that! Best video ever. I now feel more confident about asymmetric encryption.

[@anirudhpathak2559]

The best and clearest description of public-private key cryptography I have seen so far!

[@tmyh]

Great presentation, you make it easier to figure this new tech for a no-tech person. Keep the blockchain videos coming mate.

[@MegaKalkas]

You should also mention that encryption works in the other way too. An encrypted message with a private key can be decrypted only by the paired public key and this insures that the sender (or whoever encrypted the message) is indeed trusted.

[@germantarnoski7130]

Genius

[@AbhijitChandekar]

This is the best video on public key encryption. What i found was that, many other videos does not mention the fact that the public keys are exchanged between the two parties. Thank you to the maker of this video!!!

[@simplyexplained]

Glad you liked it!

[@chenbiton9469]

Really clarified this topic for me. Thank you for this video!

[@sabrinemaiz234]

its awesome how u explain thank you a lot, its beeing one year trying to unterstand this complex IT Security,but i couldnt with all videos in Internet. u just explain it in few minuts and i didnt need to repeat the video thausend time, thank you a lot for your hard work

[@fotoMwahine]

Thank you so much for this easy to understand explanation. Studying cybersecurity and symmetric/asymmetric encryption; this is right on time. Excellent!

[@Ahmad-iu8dq]

The mailbox analogy is a state of the art. Well done!

[@anandarivu]

This is the best video to understand the algorithm. I was always amused at how ssh works with keys. No one ever showed the exchange of public keys. Thanks a lot for the video.

After watching so many videos about encryption, this is the first one that makes sense to me. Thanks for the simple explanation and beautiful illustration!

Straight to the point ! Gives good groundwork to take this forward!

[@mr2_pg]

Thank you so much for this helpful video. You're communication and explanation skills are on point!

[@iCortex1]

This took years for my brain to click, it's hard to grasp when you don't have much experience (IE still in school) - but it all makes sense now :) If you're struggling with this concept don't give up, it finally clicked for me after revisiting the subject once in a while

[@emufandango]

You’ve got my sub! Thanks for the video, as I’ve been trying to understand this for quite a while, and no one else has been able to explain it to me. Simply put, Alice is encrypting the file in a way that only Bob can understand, and vice versa.

[@user-uf6fs2rn6s]

This really helped loud, clear and straight to the point!!! Thank you so much

[@Yell3x]

Thank you so much! This really answered all my remaining questions, just got taught it and asked things like, why would it be public when you can reverse the process and etc. That mailbox example really did it for me!

[@theartofhacking6896]

I was always struggling to grasp the concept of asymmetric keys but now, within only 4:40 mins it became crystal clear. Keep it up. :)

[@benny.6588]

Excellent, this kind of analogies, depicts better the problem for being understood, as the coffer or something like it, than a plain explanation declaring rules and results, because is better mentally thought in mind...beyond and respecting the math matter that is another more complex and low lever discussion. i love this class of analogy when is well applied. thanks for the video
