passing notes in class just got a lot more interesting

When you crack Caesar ciphers, do they ask "Et tu, Brute force?" Hides from impending mob.
@d.tt.wilding7740
he's telling me this so enthusiastically like if he's helping me get away with a top secret. I almost feel bad for having nothing to hide
@squee6970
Brute force is pretty effective on Caesar

Enigma is a truly brilliant approach to cryptography. The weakness is the common wording of course. So we can take common words out of the cipher altogether. When using enigma one must not use common words at all. so we can make different substitutes for common words like "the"

I learned the Caesar Cipher in 4th grade. My teacher was awesome. edit: 5th grade.
@theoneshad0w508
How about a crash course series on this? Like if you agree.

I work with cryptography and I have to say: this video is amazing. Great way to teach the history of cryptography in a way easy to understand. Also very accurate and covered the most important topics of the history of cryptography
@DampeS8N
Very nice primer on encryption with examples. Great job! I hope you do a part 2.
@Kneedragon1962
It may be worth mentioning that the 'Bombe' made by Allen Turing and Tommy Flowers, was in many ways the world's first real electronic computer. It predated the American Colossus computer by about 4 years, and inspired it. Subsequently, Von Neuman (who had worked on Colossus) made a set of recommendations, should anyone attempt to build another one of these things. His recommendations led to the building of the first Von Neuman machines. All modern computers could reasonably be described as Von Neuman machines, because 75 years later they still comply almost exactly with Von Neuman's recommendations. Codes, specifically the Enigma, gave birth to modern computers. And, much as the NSA may annoy us, without espionage, there would be no computers.

Tips for simple but effective encryption (can be programmed in python) : 1) Include spaces, commas and dots in your alphabet list as 27, 28 and 29 respectively. 2) Carry out alphabet substitution. Example : a - t, b-k, c-s ...... 3) Then, apply vigenere cipher with long key. Example : "thispasswordissohardnobodywilleverguessit" 4) Don't use capitals. It makes it MUCH easier to crack. Your end text will be completely gibberish with random dots, comma and spaces. There will be no common word lengths such as 3 for "the", 1 for "I" and others.

This was an incredibly interesting episode, I ended up spending at least an hour reading about encryption and hashing after watching it. Very, very interesting indeed.
@laurafleming4377
You should cover quantum cryptography - it's actually unbreakable

6:16 There is a movie about that called ''The imitation game''
@Suedocode
No mention of public/private key encryption (RSA/ECC) or the current symmetric key encryption (AES)? The schemes you provided are technically symmetric key encryption, and it's such an important word/concept that I'm surprised it wasn't specifically pointed out. RSA, ECC, and AES are the most important and relevant encryption schemes. A topic about cryptography is rather silly without them, even if it's only rudimentary stuff. You don't need to describe the math behind it, but mention the concepts at the very least.
@CultureStress
I'm a little bummed you didn't finish with a bit about the Navajo Codetalkers. I know it's not exactly "encryption", but it seems relevant.
N/A
"When websites announce that hackers know everything about you, that's because their encryption methods were breakable" That's not true. Most of the time the website are broken into because of unpatched or misconfigures software. It's extremely rare to be hacked because of a flaw in in the encryption methods.
@heathermarcoux294
another giveaway worth mentioning is that in your message "scishow is the greatest" you use a common two letter word, and there's only a handful of two letter words those letters could be which makes it easier to guess the proper match. Also if you had used a single letter word, there's only two possible choices because the only single letter words are "I" and "A" (assuming you're not using txt lingo)
