Amazing how Tobey Maguire is saving Mary Jane at night and teaching people about computers in the day

Mike is a legend, he explains everything so well and makes it easy for anyone to understand.

Not gonna lie, I came for the information but I stayed for the pen colour change.

When I see Mike in the thumbnail, instant click.

This actually makes a lot more sense than the previous videos on digital signatures on this channels as it actually goes into the details. It was really unclear in my mind before but this is a great explanation of what actually happens.

Absolutly love how these guys discuss immensly complex topics, yet when it comes to verifier neither is all that sure how it's spelled! I feel so seen!!!

Thank you Dr. Michael Pound. Your explanations are so clear and mind-blowing. One of my favorite channels on Youtube!

Dr Pound is one of my favorite to listen to 🤩
But I feel like it would be nice if this episode included some more information and / or details about digital signatures (maybe some extra bits?😉)

Thanks for all the videos! I've been watching them and learning from them for years

Dr Mike Pound grounds and pounds every problem till it is solved.

9:41 Remember, none of these public keys is confidential. The problem is, you have to trust they are authentic, that they really came from the people they say they’re from.

Damn. I've caught up with watching Computerfile. Now I'm going to have to wait for more episodes to come out.

I love it, like every other of your videos. I'm just wondering one thing: He can explain everything so well, why wouldn't he do something like a full structured course with lectures and covering a topic (e.G. encryption, Web security, how the iternet works, ... ) as a whole with all the most important components. I would instantly sign up for that!

Love Mike! He needs his own channel! 🤩

This video was actually tremendously helpful. I had a rough understanding of PKI with RSA, but I always thought DSA was a totally different process.

I didn't know it was (effectively) just encrypting the hash of the message with an asymmetric key

[lucast]

Any chance of a video regarding the TPM (trusted platform module ) and how it works, just finished writing an essay and it came up and I found it rather interesting, keep up the great content !

[polares]

Please do videos about all the topics mentioned in the video. Can't wait to see them.

So informative yet informal and digestable. Many thanks
