- Codes, ciphers, and mysterious plots. The history of cryptography, of hiding important messages, is as interesting as it is mysterious. I hope you enjoy! PART 2 COMING SOON.

6:17. It helps to pronounce when you realize their names are often the same as our English name. So he would be "Father of (Abu) Joseph Jacob (Yusef Ya'qub), Son of (Ibn) Isaac (Ishaq), from the House of Kindi (Al-Kindi)
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
So very much of Arab Muslim science and mathematics is of Hindu origin
You want to know a language that will give you depth whereby you'll be able to figure out hidden meanings? Classical Arabic. Arabic has diacritics and dots, but in the past, they used to write Arabic without diacritics and dots. If you learn Arabic, then learn it first with dots and diacritics, but if you're done, then go to the next level by understanding Arabic without diacritics and dots. This way you will maximize your depth. Your contextual comprehension will become better. Why is this? For example; without dots, the Arabic B, T and TH look exactly the same. So if you read without dots, you'll have to figure out the context by digging. It's like a code language. A secret language. Lots of letters will resemble each other without dots in Arabic.
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!
Amazing video! Great job!
Great video! Great channel, I am enjoying them all. Thank You
This is the video content I was looking for, at this point in time.
Thanks.
Thank you so much for this much needed breakdown. It gave me a new appreciation for cryptography.
I saw a post on Reddit, congratulations on the excellent video.
Wow that is quality mate!
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!
Absolutely magnificent
Excellent content! I’ll subscribe to you channel before you blow up. Keep it up!
This is brilliant!
Nice job, thanks
Thanks for the video!
love this video, teached me a lot. I am new to this, but I love it!
Read "The Code Book" authored by Simon Singh. It's a perfect book for people entering into this cryptography field. He gives detailed explanations of how a particular cryptographic technique developed, it's historical background and how it can be broken. He also narrates interesting historical stories regarding encryption
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.
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)
Fantastic video!
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😂
lol i though this video had at least 10k views, really well done, you deserve more recogniction
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
1:25 No mention of NULL CIPHERS, why?
Philosopher a lover of knowledge. A scientist.
Made my timbers shiver
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
The most famous asymmetric cryptography algorithm is extensively covered by any resource on cryptography.
1:37 It's pronounced "sit-a-lee" (rhymes with Italy), not "sky-tale".
I stopped the video to comment. I was going to say that is pronounced 'ski-thale".. Without doing any research I was positive that, sky-tale is wrong for sure
Nope. It's ΣΚΥΤΑΛΗ (skitalee) and the tonation goes like "italics".
4:37 you mean the 9th century?
6:16 Yaqub is Jacob
Abu yusuf, I wounder where i heard that before
Look Morse code in the red line . It could be a cipher
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
Make toilet by hindi science in india
That age isn't for one nation ots for all Muslims
not arabs wich what you think
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
Wrong, the concept of 0 was invented by the Hindi
No i am in my school so bye
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?
