Week 2c: Entropy, Encoding & Encrypted Workflows
Goal Understand entropy and randomness as the foundation of cryptographic security, learn binary encoding (Base64, hex), and combine everything into practical encrypted workflows with best practices. Prerequisites: Week 2b (Symmetric Encryption) This is Part 3 of 3 - Covers entropy, encoding, workflows, and best practices. 1. Entropy and Randomness: The Foundation of Security What Is Entropy? Entropy is a measure of unpredictability (randomness). In cryptography: High entropy = Truly random, unpredictable Low entropy = Patterns, predictable Why it matters: ...
