You use bricks. They are unbreakable encryption system. I would go on explaining it, but... This video is about bricks. Bricks are...

Missed opportunity for a brilliant sponsorship. "For the next step, you're going to have to pause this video and go learn linear algebra. You can probably knock it out in a couple months by signing up for this video's sponsor..."

You explained this really well, like an Indian on a channel with 12 subscribers.



Everyone who studied at a university will recognize that this is, in fact, a compliment.

I don’t think it’s correct to call AES the most advanced symmetric encryption algorithm. AES was revolutionary for its time, but much faster algorithms exist today (e.g: Salsa20/ChaCha20), which are also far easier to implement securely. AES is very fast today, but only because it’s actually implemented in hardware at this point (e.g: the AES-NI extensions for x86), rather than in software. If implemented in software, it wouldn’t really be competitive anymore in terms of speed. Also, AES’s design lends itself to really insecure implementations (e.g: S-Box lookups based on secret data) which lead to side channel leaks.

Wow never thought I would see this here. Vincent Rijmen, one of the 2 guys who designed this system (Daemen and Rijmen → Rijndael) is a professor who gave me algebra at university.

I feel bad for someone who actually paused this video and actually spent months learning about linear algebra and took some university classes and unpaused the video when they masted it only to find out that their knowledge is thrown out of the window

How To Design A Completely Unbreakable Encryption System : Just scramble everything randomly. You didn't say you needed to be able to unencrypt it.

I’m a cryptographer. We don’t actually know whether AES is practically unbreakable or not — in fact nobody knows whether anything can be practically unbreakable at all, if you want to use a key more than once!

The best we have is “a lot of smart people have tried very hard to break it, and they haven’t managed to”.

As someone with an academic background in cryptography, I have to say that this video is a good introduction to AES :)

Answer: Watch this video. You're now fully qualified to "Design A Completely Unbreakable Encryption System"!

Description of the algorithm is pretty accurate.... However, calling it the most advanced encryption is actually wrong. Rijndael competed against two other ciphers for the AES designation. Twofish and Serpent were the others, and known at the time to be more complex and probably more secure. However, one of the reasons Rijndael won was because it was likely easier to make performant on any hardware, and the security margin - while less than the others - was still sufficient that we could trust it.

The only encryption that can't be cracked given infinite time is a one time pad. AES is "good enough" and serves a purpose of a private-key encryption system that can allow for a short, repeatable key for many encryptions.

"Sounds like a challenge."

Pulls out TI-81 calculator.

That 256 bit password in clear text is totally something I would use and have used silliness in my passwords before.

I used to use some form of "I hate this <company>" as my work password. But funny enough, I had to let a coworker log in for me once after an injury. The laughing was fun.

I like when "Brute Force" hacking in media are just used as magic hacking words.

[andrewthomson]

Just finished watching this on Nebula but for once I actually wanted to see the sponsor lol

[evanthesquirrel]

It doesn't matter how good the encryption is if your agents keep leaving passwords on post it notes

[ezforsaken]

AES encryption is usually very breakable because devs usually implement things awfully and/or use static values for some of the parameters required to encrypt.

[durak]

Not a bad explaination for this short of a time.
I would just add that this is a symmetric encryption and there is also asymmetric encryption.
And that Websites (and many other software) use a combination of both. One of the big problems with an encrypted connection is the key exchange, because both parties need the key, but that key should not be sent, because then everyone can read it. But this is a video for its own. :D

Funnily enough had a class about this exact same topic 2 days ago. This is very well explained
