Hey! I'm David, the author of the Real-World Cryptography book. I'm a crypto engineer at O(1) Labs on the Mina cryptocurrency, previously 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.

My talk on SHA-3 and derived functions at DEF CON 25 posted December 2017

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



Great talk, but please defer chats with the audience next time ;)
