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.

Real-World Cryptography, a bit more than a year later posted February 2023

Three years ago, in the middle of writing my book Real-World Cryptography, I wrote about Why I'm writing a book on cryptography. I believed there was a market of engineers (and researchers) that was not served by the current offerings. There ought to be something more approachable, with less equations and theory and history, with more diagrams, and including advanced topics like cryptocurrencies, post-quantum cryptography, multi-party computations, zero-knowledge proof, hardware cryptography, end-to-end encrypted messaging, and so on.

The blogpost went viral and I ended up reusing it as a prologue to the book.

Now that Real-world cryptography has been released for more than a year, it turns out my 2-year bet was not for nothing :). The book has been very well received, including being used in a number of universities by professors, and has been selling quite well.

The only problem is that it mostly sold through Manning (my publisher), meaning that the book did not receive many reviews on Amazon.

So this is post is for you. If you've bought the book, and enjoyed it (or parts of it), please leave a review over there. This will go a long way to help me establish the book and allow more people to find it (Amazon being the biggest source of readers today).

Well done! You've reached the end of my post. Now you can leave a comment or read something else.
