HTTPS explained with carrier pigeons

Cryptography can be a hard subject to understand. It’s full of mathematical proofs. But unless you are actually developing cryptographic systems, much of that complexity is not necessary to understand what is going on at a high level. If you opened this article hoping to create the next HTTPS protocol, I’m […]

How Computers Make Random Numbers

Predictable Chaos How Computers make Random Numbers In software, and in engineering in general, there is necessity for reproducible randomness — numbers and images that seem random, that look and feel random, but are actually generated using definite algorithms. This is called pseudo-randomness, and we’ll be taking a closer look at simple ways […]
