Cryptography 101 with Alfred Menezes

Crypto legend Alfred Menezes just turned professor vibes into binge-watch energy with Cryptography 101 and a full playlist of YouTube courses. There’s everything from plain-English Building Blocks and real-world case studies to brain-benders like lattice math, the LLL reduction algorithm, and quantum-safe stars Kyber and Dilithium. Plus: brand-new resources for instructors. The community? Split. Alumni like zavec are having a nostalgia rush (“fantastic prof!”), while practical folks storm the thread with a single plea: stop the theory dump and give us a simple “what should I use” guide.

That tension hits peak drama when danhau begs for “a cheat sheet” — authentication, message signing, password storage — the works. Meanwhile, teleforce drops a power-up: Menezes’s classic Handbook of Applied Cryptography for free, which sparks the “homework vs cookbook” debate. Jokes fly fast: people ask if “Kyber” is a lightsaber, if “LLL” is a lullaby, and if hash-based signatures are just extra-strong hashtags. The strongest takes: academics love the deep dive; builders want flowcharts. The vibe? Professor goes Netflix, Reddit wants TL;DR. And with quantum-safe topics front and center, even non-tech readers get the message: tomorrow’s lock is different, and you can learn it here — just don’t forget the cheat sheet.
