Cryptography 101: Anish Mohammed's Intro Session at Zu-grama Week 🔐

This is an Introduction to cryptography session taken by Anish Mohammed in Cryptography week of Zu-grama on 10th Feb, covering its historical evolution, key milestones, and its relevance to Web3. Anish introduces complicated elements on cryptography, cryptanalysis, the logic, mathematics & the history of cryptography including RSA, SHA, MD5, Hash function, ZK’s (zero knowledge) & FHE’s (Fully Homomorphic Encryption). He also mentions how cryptographic methods have developed over time and provide real-world analogies to simplify complex concepts. This video highlights the Cryptographic techniques in Web3.
