This video talks about End-to-End Encryption, and basically why governments should not break it,
trying to get chat records and traces of fake messages.
Privacy is a big issue these days, and encryption is the cornerstone of all internet security and privacy.
In this video, See how it works in somewhat detail, where I will explain basics of encryption with Caesar cipher, then we will ramp it up and talk a bit about AES, talk a lot about Key Exchange protocols and Asymmetric Encryption techniques like Diffie Hellman Key Exchange and RSA, respectively.
We will also talk a bit about Trap door / one way functions, especially prime factorization.
Finally we will see the overview of Signal Protocol (and its two parts: Extended Triple Diffie Hellman and Double Ratchet), the method used by Whatsapp and Signal to encrypt its messages.
TOO MUCH TECHNICAL STUFF?
Well I end the video with a monologue about privacy and security, and why governments shouldn't break it.
Wow, I just described my whole video here.
Wish to read further about how WhatsApp's encryption works?

Thanks for watching!
Hate maths and science? You can always skip ahead, even though I recommend you watch the technical stuff.
But still, if you really don't want it, I would highly suggest to watch from 09:00 onwards, you really should not miss that.
Your channel is very informative
Brother Uttrakhand ke logon ke origin pe video banao plzz

Are bhai bhai Bhai ye math😂😂😂.
Itna time lga diya is research pe .Why the big fan sourav Bahuguna
This is the kind of content i pay my internet bill for. Thanks man!
Thanks a lot!!!😄
As someone who works in infosec, I really appreciate how you explained encryption is such simple language, and make the concept so much easier for everyone to grasp.
ofcourse one might want to argue that "encryption is a lot more complicated than that", but I honestly think that people understanding at the level you explained would already solve so much misunderstanding about encryption and why letting governments have back-doors aren't worth the cost to us as a society.
Thanks, didn’t realise this is getting views still.
Harshit brother, you are amazing. True gem of Uttarakhand. We need more youth like you in this country.

हेलो भाई जी आप विडियो एडिटिंग कौन से एप द्वारा करते हो
DaVinci resolve
Par is poore Ramayan me ye kyun nahi kaha gaya ki Pegasus message encrypt karne ke pehle aur encryption decode hone ke baad Jo signal display screen ke taraf jaata hai usko intercept karke screenshot jaisa kuch leta hai jiske saamne ye saare encryption fail hai.
10:00 😉👍
😄
Sir can whatsupp messages be traced?
Not yet.
Okk mere ek question ka answer dijiye brooo ..... Ki yadi ye WhatsApp encrypted hai or WhatsApp hmara data read nahi kr sakti to jb hm koi link WhatsApp pe paste krte hai ti wo INDEX ya Us link ke data ko fetch kaise kr leta hai ????
That all happens before you hit send and before encryption kicks in. All the processing is done on the phone in that case, you can try this:
If you paste a link and quickly send it without giving WhatsApp on your phone a chance to get a preview of your link, it will be sent as plain text link without any extra stuff.
Instagram isn’t end-to-end encrypted, and it generates the preview of the link after you send the message.
@@HarshitRautela so it means WhatsApp can read our message while we are typing ... ??
Even your keyboard knows what you are typing. WhatsApp or any other app like Telegram/signal can identify links, but that processing and data fetch is done on the phone, not on the servers of companies. That data isn’t stored and sent to the servers.

Sir can police trace whatsupp messages
Sir reply karo plz
the government will never read your messages in the utopia ecosystem. Decentralization will save this industry.
Arnab Goswami ki WhatsApp chat kaise leak huyi thi ? 😒
Not due to the failure of E2E.
Nothing... NOTHING you put on internet is safe from hacking.
End to End encryption is myth
It really isn't.
Wonderful
Thanks
