A light‑hearted tour of the quirky ways we coax randomness out of lava‑lamps, Geiger counters, ambient noise, and good‑old motherboard sensors, because good cryptography needs a little chaos (and a lot of fun).

A dive into a custom ISA for RSA: modular‑instruction shortcuts, multiply‑subtract tricks, and exponentiation‑by‑squaring hacks that shave a few cycles off the dreaded big‑number math.
