Hey! I'm David, cofounder of zkSecurity and the author of the Real-World Cryptography book. I was previously a crypto architect at O(1) Labs (working on the Mina cryptocurrency), before that I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

The Real-World Cryptography book is done and shipping! posted September 2021

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.

Thanks David, my book just arrived in the post despite some serious mail delays in Sydney, Australia due to various COVID outbreaks.

Going to love to spend some time going through this, and so far the content and illustrations are great. Keep on cryptin'!
