The Mathematics of Cryptography

►My Setup:

[jordancarpenter]

Simon Singh wrote a famous book detailing all of this in 1999 called “The Code Book”. With an impressive challenge of 10 ciphers to beat at the end that had a monetary prize. It was fascinating.

This is one of the coolest math YouTube videos that I'v seen.

I was half way through then I released I hadn't yet subscribed, my bad dude. Love your channel

[sahilkthakur]

Because of you I'm learning mathematics with curiosity and meaning.👍👍👍

[Engel-olrm]

Your channel was one of the factors in me wanting to study mathematics

[ilyaaslunat]

This is a really good video. I’m doing coding and cryptography as a module in my final year maths, and your covering the main points 😁😁😁

[pravatyadav]

Ur content are always original and exciting....makes me want to rewatch it time and again

You ever think about changing the name of your channel? You are doing lots of new amazing videos that are more geared towards the applications of mathematics to STEM fields, as opposed to talking about college majors as you did more frequently in the past. I like this transition of content in your channel as it attracts a wider audience instead of just college students. You could grow huge if your channel focused on these types of videos. Your college major videos were great and informative in the past, don't get me wrong, but now you've established a theme of mathematical applications that make your channel really unique and interesting!

Perfect in terms of detail, depth and presentation, thank you. On a level that I can just about grasp most of it, but not all of it without stopping and perhaps writting stuff down. I wish more topics were covered on YouTube on such a level.

I would like to recommend "The code book" written by Simon Singh

Honestly I really don't like doing math but this was so much fun to learn

[behnamasid]

You explaining things could not get any simpler. I'm really happy to be a subscriber to your channel

Today I learned that literally every number you can possibly think of had at least one thing in common.
Relatively prime.

The problem of passing notes in class is NOT ONLY that of secrecy. If someone knows that you have passed a note, even if they don't know what's in the note, you are STILL in trouble. Therefore, you have to (1) conceal the _contents_ of the note; (2) conceal the very _existence_ of the note.

100 youtube tutorials later I finally understood modulo arithmetic!Dude you a genius.

BEST VIDEO THAT EXPLAINED THIS MATH PROPERLY

I'm about to go to sleep and this is the perfect way to start a good night's sleep. Very good presentation. Keep it up.

The beginning, one after the caesar cipher, is actually called the Vigenerre cipher! It's much easier to decode with an alphabet grid- you use one side as the ciphertext letters, and the other for the Key phrase. Match each letter in the ciphertext to its key counterpart and bam. Same deal for encryption.

Cryptography was my second favourite module in my Maths degree.... only behind Number Theory ;)

Best video I have come across so far. Thank you for sharing!
