This was very well explained. Thank you. It amazes me how some modern textbooks are written by people who likely can't even explain the concepts in person.

and you also explained the name of 'XOR' . shouldn't we know the nature of a thing and then learn how to use it. it's really a good way to learn everything!
it's really a wonderful video explaining xor and encryption. compared with all other ones i watched this one just makes everything simple and easy for understanding. thank you! and i'm looking forward to more videos from you!!
what would happen in a situation in which there is an 8-bit symmetric binary encryption key, but a 16-bit binary value to encrypt using the XOR method. For example with a credit card number, turning each of the individual digits into 4-bit binary values, then combining every 4 into 16-bit chunks then encrypting them.
encryption is achieved by the function Y= E(K, X). using this function and given the key 1010011001, encryption the message 0011011 using the AND principle.
Original ASCII codes ARE in binary. Computers transmit them with pulses of electricity and store them with devices that can be on or off (such as transistors). We express ASCII codes in denary (base 10), and sometimes hexadecimal (base 16) because that makes it easier for computer scientists to talk about them. The XOR cipher only works with binary digits. You can't XOR base 10 numbers together. I'm not aware of a base 10 equivalent. Interesting question! :)KD
coming from a professional procrastinator, this video was very well put together and easy to follow. thanks a lot!
You are very welcome. Thanks for getting around to commenting :)KD

Thanks. If you don't mind, I will add these to the video description, so they become chapters? :)KD
First time I was able to put the XOR decryption process to practice, feels good thank you.
Delighted to help :)KD

This channel is a goldmine, thank you so much for your extraordinary work!
it's really a wonderful video explaining xor and encryption. compared with all other ones i watched this one just makes everything simple and easy for understanding.
thank you!
and i'm looking forward to more videos from you!!
Agree wonderful is the word I also typed. I was feeling like a moron for not understanding until I found this ! Mind blown!
Your explanation is unquestionable and I like how clear your voice is, keep it up! I've subscribed :)
Welcome aboard. :)KD
well summarized and easy to understand, nice video!
Here's the answer (spoiler!)
decrypted binary -> 01111010 01101001 01110000
decrypted ascii -> zip
Thank you :)KD
Well done.
Thanks for sharing your knowledge with others.
My pleasure :)KD
Thanks for the effort in making this video. It really clarify and thought us how to think about symmetric cryptography. 👏🏻
my pleasure :)KD
Simple and easy to understand. Thank you.
Beautiful explanation, thank you very much.
You're most welcome :)KD
This is SOOOOO appreciated.
You're very welcome :)KD
Great explanation boss!
Awesome video! TY 🔥👍
Very nice explained... THANK YOU
You are welcome. :)KD
Its really helpful 👌👍 thank you
excellent explanation! Thanks!
You are welcome ,and thank you :)KD
So clear, thank you!

Interesting question. Why not give it a try? :)KD
encryption is achieved by the function Y= E(K, X). using this function and given the key 1010011001, encryption the message 0011011 using the AND principle.
Awesome video
btw you make excellent videos! Are you involved in cyber security or computer engineering in any way?
Just a computer science teacher.
Computer Science JUST!! a computer science teacher, I think you're doing a great job
❤️ed your explanation
Thank you :)KD
can you do this without using binary digits? Like just with the original ASCII code?
Original ASCII codes ARE in binary. Computers transmit them with pulses of electricity and store them with devices that can be on or off (such as transistors). We express ASCII codes in denary (base 10), and sometimes hexadecimal (base 16) because that makes it easier for computer scientists to talk about them. The XOR cipher only works with binary digits. You can't XOR base 10 numbers together. I'm not aware of a base 10 equivalent. Interesting question! :)KD
good and easy explanation
:) thanks
Thanks for the comment. :) KD
The Vernam Cipher introduced this concept when it was patented in 1919
perfect explanation thanks!
Thank you. You are most welcome :)KD
if you guys wondering what was the result of encrypt the letter 'z' it was '/'' :)
this helped me!
YW :)KD
To the point! Thank you
what is the answer of this question
Not telling :)KD
Just wonderful wow
Thank you so much 😀KD
Thanks.
You're welcome :)KD
10/10
Thank you :)KD
Super
Thanks :)KD
Fucking good
