How End-to-End Encryption works | The Signal Protocol and Privacy Vs Security

English subtitles are available now! 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?
