the entire semester i did not understand this but only 5 min i got it, thank you Sunny

Sunny, you are a treasure! I'm so grateful I stumbled upon your channel. Your explanations and visuals break the topics down so that it's so understandable. Thank you, thank you, thank you!! 🙏🏻

I must thank you sunny for wrapping up the whole topic meant for 1 and half hours in just 5 minutes. It was really educational and useful.

I can’t believe I didn’t stumble upon your videos earlier while studying for the CISA. Domain 5 has had some difficult concepts to understand and taking even 30 min to watch a few of your videos has finally made concepts click. Thank you so much, you’re a wonderful teacher!

Sunny, I just wanted you to know that today I provisionally passed SSCP and I would have not achieved it without your youtube lessons. You are the best teacher any student could hope for!

Sunny, your explanations are spot on. In your Public key video, you made clear, that the process starts with the receiver. Here you pointed out, that digital signature and encrypting the message are two distinct things. I watched a ton of videos to understand those concepts. No one made these differentiations. Hence, they are critical for the understanding. Thank you very much for your work.

Thanks for explaining this and other topics so clearly! I have watched lots of other videos by professors, experts and students but they all miss the point. You explain this and other topics so logically and clearly that it's a pleasure to watch. Thank you so much!

you explain it very well - the logic is sound and easy to follow unlike some people that gets trapped in the technical details before explaining the basic steps

You make any topic so simple yet clear. Thank you very much Sunny, I have always referred to your videos when in doubt.

You explain this better than anyone, Sunny. We are so blessed that you are on KZread. There are ones that talk for 1 hour and don't explain it as well as you have in 5 minutes. Thanks for explaining it so well!!!!

You are welcome! I am glad it helped.

Great explanation! Thank you! I only want to add that the reason we use a hashing algorithm before encrypting a digest, is to make the digital signature small. Because if the plain text message was 10GB in size, then using a hashing algorithm on it creates a small string of only a few bytes. But we if created the digital signature from the entire 10GB text message, then we would have to send 20GB worth of data - 10GB for the original message, and another 10GB for the digital signature used to verify that it was signed by Bob. In case anyone else was wondering why we use a hash algorithm to create a digest, before encrypting it with the private key to create a small digital signature. Remember, if any small change was made to the original message, the digest would be completely different, and that's why we can use this method to decrease the size of the digital signature.

I love this guy's videos. Simple and clear.

It's embarrassing how little I understood about this, and remarkable how clear this video makes the subject. Well done.

It was a very elaborative with example which i struggled a lot studying books and youtube it to clear my confusion. I appreciate the way you explain straightforward and simple.

Bob, I agree with the other positive comments. This is the absolute best explanation of digital signatures with email or memo that I have seen. Great job and thank you for this. 👍🙌

Sunny, you are my favorite. You are making it easier for me to understand things.

The best description of this topic I have found, very helpful, thanks very much!

Thank you Sunny! I was preparing myself on your channel for the cryptography exam for my dream job. I got the job and I explained digital signature, hash functions and PKI exactly the way you do on your channel. Thanks to you I had the best written exam among all the participants. Keep doing the great job!

Have a nice day sunny and please don't forget to enjoy yourself!

Finally I've managed to find a youtube video on this topic which makes complete sense thank you. The graphics explained this very well and now i understand at last
