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.

The Real-World Cryptography book is done and shipping!

blog

Today I received the first copy of my book Real-World Cryptography! You can’t imagine how much sweat and love I put into this work in the last two years and a half. It’s the book I’ve always wanted to read, and it’s the book I thought the field was missing. It’s the book I wanted to have as a student when I was learning about hash functions and ciphers, and it’s the book I wish I could have referred to my fellow pentesters when they had questions about TLS or end-to-end encryption. It’s the book I’d use as a developer looking for cryptographic libraries and best practice. It’s the first book with a cryptocurrency chapter, and it’s the book cryptographers will read to learn about password-authenticated key exchanges, sponge functions, the noise protocol framework, post-quantum cryptography, and zero-knowledge proofs. Real-world cryptography is what the field of applied cryptography really looks like today. It’s all there.
