Wrote a deep-dive on ML-KEM (FIPS 203): the post-quantum key exchange already shipping in Chrome, AWS, Cloudflare and the Linux kernel.

Fully interactive rundown, covers everything from polynomial rings and Module-LWE to encapsulation, decapsulation, and why the Fujisaki-Okamoto transform turns a toy into a real primitive.

No hand-waving. Actual math, actual intuition.

A Hacker's Guide to Post-Quantum Cryptography: ML-KEM & FIPS 203

Everything you need to understand the algorithm that's replacing RSA (in terms of Key Exchange), from polynomial rings to key encapsulation, with zero hand-waving.

The Futility of Lava Lamps: What Random Means

이 글은 Cloudflare가 인터넷 암호화에 사용한다고 홍보하는 용암 램프 기반 난수 생성이 실제로는 보안에 큰 기여를 하지 못하는 '보안 극장'임을 지적한다. 난수의 본질과 암호학적 의미를 설명하며, 일회용 패드(one-time pad)의 원리와 한계, 그리고 현대 암호화에서 256비트 키를 사용하는 인증된 암호화 방식이 어떻게 훨씬 효율적이고 안전한지를 상세히 다룬다. 또한, 난수 생성은 단순히 물리적 불확실성보다 키 관리와 정보 이론적 관점에서 이해해야 하며, Cloudflare가 실제로는 256비트 키에서 파생된 스트림 암호를 사용해 대규모 트래픽을 암호화한다고 설명한다.

Money moves in seconds. Contracts sign themselves with keys. Parcels track in real time.

Then we vote — with a pencil, on paper, handed to a stranger.

A quiet look at what verifiable digital voting could actually look like, and what the old system might really be protecting.

The Case for Verifiable Voting: Why Paper Is the Last Analogue Holdout

We trust cryptography with our savings, contracts, and parcels. Then we vote with a pencil mark on paper and hand it to a stranger. A look at what verifiable digital voting could actually be.

@bascule "Made you look". Comparative FFI study this AM. I had reason to examine #PyCA #cryptography after reading @filippo and seeing it used #CFFI, not #Cython, and Rust-ified its underlying #OpenSSL API exposure with #C linkage using #Rust #unsafe blocks. Go figure. I just use #libsodium for most things because it ROCKS.
