this video DEFINETELY deserves more views. You have done a very good job sir

[@jaosberg]

Fantastic video! Well produced and a great focus on the "why's". This video is a gift to all CS-students.

[@valeriewang1473]

I like this reasoning perspective on why should we use this algorithm! this video definitely deserves more viewers

[@abreue5127]

Congratulations! Thank you for the content!

[@FreeDomSy-nk9ue]

Awesome stuff. Thank you

[@blowingupblocks]

thanks for the wonderful vid!

[@citclayton]

this video deserves more views!!

[@maksudahossain8482]

Excellent!

[@1UniverseGames]

Is it possible sir to show it in programming perspective like how it implemented. It will be helpful, also a bit of its Mathematical explanation

[@yannicklittek3314]

MAC explanation at 12:35

[@raquelbibi1436]

Please make a video about number two factor authentication (twitter) I got so confused cause give me so many numbers

[@lobaandrade3091]

okay so i was pirating movies and later that day i wanted to look at my grades but then i got an error message while signing in saying an attacker changed something. edit: i just turned on cookies and it works now lol

[@gam__04]

this video is so complicated 😧😧
