cryptography, security, and random thoughts

Hey! I'm David, cofounder of zkSecurity, research advisor at Archetype, and author of the Real-World Cryptography book. I was previously a cryptography architect of Mina at O(1) Labs, the security lead for Libra/Diem at Facebook, and a security engineer at the Cryptography Services of NCC Group. Welcome to my blog about cryptography, security, and other related topics.

I was a bit frustrated with the look of this website. In spite of people complimenting it a lot over the years, it felt like it had badly aged.

I’ve also slowly converted my dynamic websites (a lot of them being old PHP websites from back-in-the-days) to static websites. I know understand that it’s just so much less pain to manage static websites. I was against that trend when it happened a long time ago, I now realized that I was wrong.

The advent of AI and coding agents have made that task easy. I just have to get them to write a script to convert everything to static markdown files, and then another one to render a webpage from them. It doesn’t make too much sense to use frameworks like hugo at this point, it’s so easy to just build everything from scratch with an agent.

Anyway, here’s the new look, hope you like it!
