End to End encryption

In this video, I explain how End-to-End Encryption (E2EE) actually works by building and using my first npm package: kush-e2e. Instead of only discussing theory, we implement a complete encryption flow using modern cryptography concepts like ECDH key exchange, AES-256 encryption, and public/private key cryptography. We'll cover: • What End-to-End Encryption is • Symmetric vs Asymmetric Encryption • Why ECDH is used for key exchange • How a shared secret is generated • Encrypting and decrypting messages • Building and publishing an npm package • Using the kush-e2e library in JavaScript/TypeScript GitHub Repository: https://github.com/kushkumarkashyap7280/kush-e2e NPM Package: https://www.npmjs.com/package/kush-e2e If you enjoyed this video, consider subscribing to SUDO INIT for more content on JavaScript, TypeScript, System Design, Security, Backend Development, Open Source, and Computer Science.
