Public Key Encryption (Asymmetric Key Encryption)

In public key encryption, two different keys are used to encrypt and decrypt data.One is the public key and other is the private key. These two keys are mathematically related. They come as a pairs.

The public key encryption is also called asymmetric key encryption because two different keys are used.

Public key algorithm is used for different purpose from private key algorithm. It is used for verification and authentication.

In this video, I will use an example to demonstrate how to use public key.

When I watch educational videos by someone who doesn't have English as their first language I often find them hard to follow and I lose patience and stop watching. But your way of explaining things is absolutely brilliant! Many teachers talk too fast, but you give the brain a chance to absorb each piece of information one at a time, because you explain each point slowly and clearly. I'm going to watch all your videos Sunny. They are the best!

Hey Sunny! I just passed CISSP and used your videos to understand digital signatures, PKI, Kerberos. You are the best teacher I ve seen in my 32 years!

Thankyou so much Sunny, you have saved my sanity. You are one of the few people on all of you tube that point out that the reciever initiates the the sender, I have been going crazy but now it makes perfect sense!!!! Best wishes from Scotland and thank you again

[proptbro]

Best explanation on youtube thanks for clearing my confusion

[jamesharris]

I would love to see more videos about different algorithm types. Your explanations are so easy to understand. Thanks again Sunny!

Asymmetric key starts with the receiver having the private key - seems like everyone else failed to mention it, hence the confusion . Thank you for clearing that.

[tonydebaka]

i have watched about 20 videos explaining public and private keys. none come close to the way you explain them. thank you Sunny for such a marvelous, simple and easy to follow explainatiion. job well done

[christopherbrooks]

Thanks so much for making these videos. I hope your channel gets a lot more recognition. I appreciate your teaching methods, it really allows me to understand.

[ESEben]

Such a clear explanation about asymmetric key encryption! Thank you for the video!

[chillasey]

Sunny, I was reading this in my textbook and didn't quite understand. It made sense when you showed the diagram that showed the receiver is the one who generated the pair of keys for encryption. Thanks!

I read these topics many times, but when I saw this video 1st time I understood this process with your very simple and short explanation, thanks a lot Sunny.

Just want to say that you're my go-to guy when I need some tech explanation. You make it very easy to understand! A BIGH MAHALO to you Sunny!

[luisdelorbe]

My opinion is the same one of Tedwood Peacock's... Your explanation is exactly the one for us who begin in this wide world of computing.
One more time, professor Sunny, congrats!!... Please do not stop your videos!!

[mattredgate]

Similar to other comments on this video, you are the only person who states the process starts with the receiver! It all makes so much sense to me now. Thank you.

[Hanna-ynou]

These videos by Sunny are fantastic! SOOO helpful! Thank you!

[Deltainteractive]

Excellent work Sunny! Please keep making these videos.

[adamtechdays]

Sunny, your explanation on such a technical subject is excellent. Keep up this great work.

[mugume]

As always, you do an awesome job Sunny. Thank you so much for your wonderful videos. Keep going bro!

[uzmamahfooz]

My O Levels books didn't explain this topic so well. Great job!

[Userforeverneverever]

Great job on the video! I hope your channel grows!
