Secret Codes: A History of Cryptography (Part 1) 

This is an amazing episode ! If you continue doing interesting content like this then your destined to blow up ! First video I have seen 9n the ancient history of cryptography !

Fabulous! Can't wait to incorporate this video into some lessons for my students this fall. I learned a lot!

Thanks for finishing the video at just the right time the baroque piece ended.

Loved your video. Please make more such content!

Thank you so much for this much needed breakdown. It gave me a new appreciation for cryptography.

Great video! Great channel, I am enjoying them all. Thank You

I saw a post on Reddit, congratulations on the excellent video.

Amazing video! Great job!

This is the video content I was looking for, at this point in time. Thanks.

Absolutely magnificent

I really appreciate how respectful you were talking about my faith. It’s often that the Islamic golden age, the prophet Mohammed and his Hadith are not talked about so positively from a western perspective, so to hear it from you is refreshing. Thank you

love this video, teached me a lot. I am new to this, but I love it!

hey hey! Great video and fluid presenting! Just a friendly reminder about the findings of Ancient Egypt my friend: 1900 BC - The earliest known implementations of the use of cryptography date back to the Old Kingdom Of Egypt circa 1900 BC. Found carved into the wall in the main chamber of the tomb of a nobleman Khnumhotep II, were non-standard hieroglyphs. These are not thought to be serious attempts at secret communications, however, but rather to have been attempts at mystery, intrigue, or even amusement for literate onlookers. Though the inscription was not a form of secret writing, but incorporated some sort of the original text, and is the oldest known text to do so. 1500 BC - Somewhat later, clay tablets were found from Mesopotamia with inscriptions of enciphered writing that is clearly meant to protect information. The oldest dated at 1500 BC and was found to encrypt a craftsman’s recipe for pottery glaze, presumably commercially valuable. So grateful to be able use and innovate with tools left by the ones who came before us and, I am so grateful for insightful and informative videos like yours :) Keep up the great work!

Wow that is quality mate!

This is brilliant!

Thanks for the video!

Fantastic video!

Great video! Quick error that I saw though. You put Sparta on the wrong side of the Peloponnesus. It should be on the bottom right, not the bottom left.

Excellent content! I’ll subscribe to you channel before you blow up. Keep it up!

3:05 to 3:06 and this is why I love Monospaced fonts. The example doesn't use a mono-spaced font, so the letters do not properly align. (as P and Q in a normal font, use a different amount of space)

Nice job, thanks

7:27 “This is such a good cipher no one will ever break it never ever.” I used to do this stuff as part of a school club

Philosopher a lover of knowledge. A scientist.

There was once a wazir who eas fluent in STANDARD ARABIC, the Caliph wanted to bring him immediately for a trial. The Caliph writer who was a friend of that wazir made just one subtle intended grammar mistake. Once the wazir read that message, He quickly understood the trick and fleed for his life. They say the Caliph pardoned him ans said laughingly: If he is that genius, we need him here, and whipped the writer, then gave him some golden coins😂

Made my timbers shiver

lol i though this video had at least 10k views, really well done, you deserve more recogniction

1:25 No mention of NULL CIPHERS, why?

3:47 is how your keyboard is ordered lol

What about the Peasant's Revolt use of coded messages?

The Gallic wars took place BC, not AD, right?

Can you share with me some references concerning the algorithm RSA

6:16 Yaqub is Jacob

1:37 It's pronounced "sit-a-lee" (rhymes with Italy), not "sky-tale".

Look Morse code in the red line . It could be a cipher

Abu yusuf, I wounder where i heard that before

4:37 you mean the 9th century?

They were the dark ages compared the past & the future.

Old CGP music

Lmfao funny

5:01 That Islamic Golden Age was based on Hindi science and mathematics

do you know that arabic people was the best at it cyphering cendy or so many many arabic people and the zero was made by arab

Why do you think that Caesar was a dictator? Greta educational video spoiled by dumb statements.

do you recommend books like "Cryptography for Kids - Kids' Guide to Secret Cipher" to help my kids to understand cryptography?
