Public Key Cryptography - Computerphile

so this NEEDS then one way encryption? Like there's no wsy for this to work without it

Thank you

I understand that the more complicated explanation for this and yet fully appreciate your simplified description. Even when they full description of how it works is provided in chinhoyi start with your simplified description and then move on from there. Perfect perfect. Nice work!

iIcan't for the life of me find the most commonly used functions for asymmetric encryption. Can somebody help me out?

This is so clever and a very nice explanation as well

i still don't understand how it works.

Gold this Video is!! Making sense of the PKI within 3 minutes!!! So great to be alive at this time!

thank you for the gem! , easily explained !

the force is with this one

absolutely brilliant presentation. a clear, concise overview of the technology anyone can understand, in just five minutes.

🙏

But if you use the same public key every time people will be able to crack it? So you need to make a new every time.

If I'm there right from the beginning, when you and X exchanged your public keys, wouldn't I be able to read what you send to one another?

i can't find a concrete example. Everyone explains the process, no one offers an example.

Amazing Explanation Bro

Thank you for simplifying

Nice explanation! 😃

Awesome explaination, keep it up!

You know you’ve come to the right person to learn about Bitcoin and Cryptocurrency, when he started to explain how money works. There’s respect in explaining something that might be common sense to some, but not to others

Investing is a way to set aside money while you are busy with life and have that money work for you so that you can fully reap the rewards of your labor in the future. Invest wisely.

wooow now that's interesting!! I'm taking a university course on Cryptography almost finished with it, and I just understand this concept now haha. Well explained thank you so much!

something encrypted with the pubkey can't be decrypted with the pubkey?

The best explanation of the basic concepts ever! Thank you

this was super easy to follow -- thank you!!

This is a beautiful explanation

what does the G in PGP mean?

brilliant.... thanks

They've made crypto easy to buy and greed rules

Well explained in a simple, easy to grasp format!

Interesting 😇

This made my day.

Genius and brilliant

Before this video, I didn't know that I didn't know what is Public/Asymmetric Encryption. Beautiful Explanation.

just marvelous... Effortless learning...

amazing and clear explanation

Appreciate your video a lot! Now I got the AHA moment

el barto was here

I really appreciate the maker. It awesome

I love this video

Great explanation!

Thank you for this explanation. Really, really helpful, especially because the digital signing part is also clearly explained.

Genius

Wish I've found this before I've tortured some poor tech souls to death with my questions about PKE. But it would have been also nice if you told about public key fingerprint and the common practical ways of veryfying it. Because it's not so obvious, for those who hasn't used PKE before the problem of how to send it so that no one could tamper with the fingerprint if you need to verify fingerprint (and for that - to send it) in order to be sure that there's no tampering. Or, what's the point of sending your PK fingerprint in text in the same message where you send the PK itself if the bad actor can theoretically switch the real PK with this own and also change the fingerprint for it in that same message?

I didnt get it...

Algorithm.

28th Constitutional Amendment: Right to Encryption
Kidding, you already have that right
...or do you?

now i can safely say i know symmetric and asymmetric key cryptography

This is the best explanation on the internet.

Great video. When I don't understand something, I look for a different explanation and then I usually find it was very simple, but bad explained the first time.
