End-to-end Message Encryption
https://arpitbhayani.me/masterclass In this video, we find how to implement a very very simple version of end-to-end WhatsApp-like message encryption. This is not even 1% of how WhatsApp does it but it gives a fair amount of idea on how we could do it. How do WhatsApp, Facebook, Signal actually do it? Answer: The Signal Protocol We do it with a very simple Public Key Cryptography and a Digital Signature. # Arpit's System Design Masterclass I teach an 8-week cohort-based course on System Design - a masterclass that helps you become great at designing scalable, fault-tolerant, and highly available systems. The program will have a blend of Live Classes happening on weekends, 1:1 Mentorship sessions happening on weekdays. The program is designed to be intense and crisp to accelerate overall learning.
