Encryption as Fast As Possible

How does data travel around the internet without becoming publicly visible? Encryption! But what is encryption?...

I type with gloves so they can't get my fingerprints

Am I going crazy, or is his voice fluctuation in pitch/squeakiness?! :0

Nice video, but you might want to add an important thing in when you talk about this again. All encryption can be broken, but it's about it being resource intensive. For example, AES 256 can be broken, but it will take a computer about 10, 000 years to go through all the possible combinations that the password can be. However, a weaker encryption may take a few seconds or minutes.
(It's like other locks. No one would use a bike lock to protect their bank because it's not resource intensive enough. However, no one would use a bank lock to protect a bike because that's too resource intensive for the end user. But in both cases, you can break any lock if you have the right resource (equipment and time).)

Simple example of encryption: 
1234 => Your password
5=> encryption key
(1+5)(2+5)(3+5)(4+5) = 6789 => encrypted password.
Encryption key received by recipient => -5
So
 6-5;
7-5;
8-5;
9-5;
and voila

Did anyone noticed Linus's tabs "contract killing", "laundering" and "hire hitman"?!!

[TehOnlyShoe]

Well, I learnt a new lesson today. Throwing knives in the air is okay because Linus does it. Thanks Linus! My mother will be proud of me :D

WHO DOESN'T LOVE THIS FAST AS POSSIBLE VIDEOS AS I DO!? Thank You Linus Sebastian! Keep the greatest content up! :D

In Soviet Canada, Linus FOLLOWS YOU !

[Stikeofficial]

Was he actually throwing a real knife into the air and catching it :O. Also 89'th viewer here :D.

Just FYI"
LOLD me more then the green linus.

Linus, u (and your team) are awesome. Thanks for everything :)

[limitlessgames]

Always wondered what the little padlock was....You learn something new everyday. Usually encryption dosent make sense to me but this did! Thanks so much!

[Muriqa]

Hi Linus,
The server room is on fire again.
Just for your information.

Sarcastic. :)

[shrimpy]

Came for the encryption explanation, stayed for the guy's funny voice

[EBackwards]

You know what Linus, when I watch your video at 2x times the speed... your voice changes very little 0.o

Side Note: I've been sending my clients here as of late so they can learn more about anything computer related so keep it up!

Did you even read more than one article on this topic? Asymetric encryption like you explained it is usually not used to encrypt data. It's used to encrypt the session key of a symetric encryption algorithm to transfer it securely over the internet. That symetric algorithm is then used to encrypt the data.

[Fantasma]

Actually most public key encryption algorithms (like RSA) have a really high computational complexity, so they are used only to share the keys used by other symmetric algorithms (like AES128/192/256). Those algorithms are the ones used to encrypt the actual data. You can see that in the padlock of the web browser.
