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.
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
same
likewise
Same! This totally makes sense to me now!
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
You're the first one who noticed the address! Thanks for the kind words ;)
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.
everyone talks about keys here and there but nobody mention the interchange step... good explanation!
As an American I can honestly say 221 baker is literally the only address I know in that entire country.

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.
+Kai Rollmann jep, 100% true. Should've added that to the video.
And after that, probably how RSA can also be used to sign and verify data integrity.
I never thought about it! Great!!
Thank you Kai Rollmann
I believe that is how Pretty Good Privacy works.
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!
Great introduction, even for non-technical people. Thanks a lot! I'd love if you could make a similar video to digital signature.
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!
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 :)
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!
Excellent video, I’ve been watching many videos about this topic and you’re the only one who I actually understood from. Wonderful Job ❤️
This is the first time I actually understood this after watching many videos about it. Thx
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.
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.
The best and clearest description of public-private key cryptography I have seen so far!
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.".
High levels of security with mathematics.
Mathematics that provide high levels of security.
Holy lil fuck! Thanks!
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.
@@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
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
You deserve so much more subscribers.. Hats off
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!
Great presentation, you make it easier to figure this new tech for a no-tech person. Keep the blockchain videos coming mate.
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!
excellent video, i had so much confusion with private and public key stuff ..you explained it so beautifully..your channel deserve the title
Thank you this is my first comment in the UA-cam you deserve it. Thank you.
This really helped loud, clear and straight to the point!!! Thank you so much
Best explanation of this concept I have come across so far. Thanks!!
Thanks man... I watched a lot of videos but was not able to clearly understand the exact concept, then I came across your video and yoo!! I understand the concept in no time... Thank you so much 😇😊
Straight to the point ! Gives good groundwork to take this forward!
Very nice and clear presentation
Thank you very much! First time I'm trying this new way of creating video's. Glad you liked it!
Firas almannaa what the different b/n Encryptions and programming

Omg, dude, this was so straightforward; thank you very much. Cryptography is one of those areas that blows my mind, and today I understood it with a simple video of you.
Thanks, you summed up a 2h lecture in 4 minutes. Lovely!
Brilliant explanation, thanks! I've been wracking my head over this for ages and then I saw this video. It makes way more sense now!
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.
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!!!
Glad you liked it!
Short, sweet, and to the point. Thanks for this great info condensed in short amount of time.
Really clarified this topic for me. Thank you for this video!
Thank GOD, finally I understood the concept, after days of research, this video and youtube channel should be on top))) Simplicity is genious.
Thank you so much.
Thank you. Watching mins before next lecture so that I stay aligned
Thank you so much for this easy to understand explanation. Studying cybersecurity and symmetric/asymmetric encryption; this is right on time. Excellent!
Which cert?
The is the best video on internet for this topic. Thanks a bunch!
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.
Glad you liked it! Cheers!
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.
Genius
the only video that explained it properlly, thank you very much!
Very pedagogically explain. Thanks, keep up the good work!
Thank you so much for this helpful video. You're communication and explanation skills are on point!
Excellent video. The most well explained I have found so far on the internet!
Damn. I understood after trying to understand for months. You're a life saver. Thanks for your amazing work.
This is probably the best explanation of this on UA-cam
Good content! the explanation is very easy to understand. I hope all concepts in this world has videos that explained them as good as this.
Thank you for explaining this in a way that now makes sense to me!! Much appreciated!!
Clear and concise. To the point with great graphical representation.
The mailbox analogy is a state of the art. Well done!
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
The mailbox example nailed it.. Thanks for the ghaphics and explanation.
The only video that help me to understand the topic really well. "Mathematically linked with each other..." is the key phrase of understanding. Thanks for video.
Your channel is amazing. Keep them coming!
thank you. finally someone who can explain
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
This solved my confusion very easily. Great presentation
Watched some of your videos - they are really cool, informative and accurate enough. Great job and thank you.
Really nice vid, clear and straight forward with a non-IT person like me. Thank you very much
You have definitely lived up to your channel name with this one. Nice work.
Finally! I understand this! Thanks for a clear, simple explanation.
It's really funny that I went through many short video but none was found an easy way to understand this concept.
This video and the analogy of mailbox messaging made the concept more easy to understand. Thanks
Simple and clean explanation. Kudos to you
I was able to understand how asymmetric encryption works in just 4:40 mins! Thanks a lot!!!
Just what is it, not how it works
Simply explained! I really enjoyed the video. Thanks for this.
Great job! I'm just going through Bitcoin's whitepaper and this video helped me a lot with understanding the mechanism behind bitcoin transactions. Thank you!
Fantastically explained! Thank you.
great video, thanks! the best explainer videos like this one take a complex topic and simplify it
that's very smooth explain of asymmetric encryption.
I have read many paragraph to learn that but i didn't understand.
very heplfull. thanks for that
Finally a video that explains it correctly and super clearly.
Excellent explanation - greatly appreciated!
Watched three videos on symmetrical Encryption , only this one made sense to me , good video
Brilliantly, simply explained!
Finally Understand it. Thanks man!
Best and simple explanation.. Thank you
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. :)
rightly and it is prosper.
Video truly worth watching. Thanks for the vivid explanation
Perfect explanation, better than my lecturer and now I got the idea clear.
blessed are the souls who impart such valuable information for free
Great explanation. It would be great to see you explain how you can be sure that you’re using the Alice (or bob) public key and not an attacker public key who would be in the middle.
sweet and simple , just what i needed , thanks a ton
I have a Cyber-Security Test coming up Tuesday. These videos have helped me a lot. Thank you.
Best explanation of this on youtube.
Perfect explain !! Thank you for your effort
You cleared my confusion. Thanks a ton. Good presentation too.

Beautifully explained. Thanks!
I now have a better understanding.
Beautifully put, thank you.
Thank you, this was a very good refresher and a great example to share with students.
Very good and clear explanation, thank you!
This video really helps explain this concept. Awesome presentation
Amazing illustration , Thanks so much
Clear and concise! Thanks!
Thanks for this. It is well explained and very easy to understand. Keep up good work.
thanks for helping me understand this concept!
Best explanation I have ever seen
Thank youu so much for this easy to understand explanation! Truly truly helpful :)
Thank you.. the concept was really well explained :)
