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.

Atom invites posted March 2014

I have two invites for the new IDE by github. I can't try it because I don't own a mac and there are no versions for windows at the moment (not even linux). Weird, but eh, if you own a mac and want an invite just ask me in the comments !

Elliptic Curve Cryptography posted March 2014

A video I found about Elliptic Curve Cryptography that talks about the Discreet Logarithm Problem and the Diffie-Hellman Handshake with ECCs. Class is in english, with bits of german and even some french :)

Such a nice lecture, Christof Paar makes me think of a younger Gilbert Strang, seems to be a great professor. I was captivated until the end and I started liking ECCs again :)

Matt Whitlock - Elliptic Curve Cryptography, the Foundation of Bitcoin posted March 2014

Great lecture from Matt Whitlock, the video's quality is a bit off but the talk is really easy to understand and nicely paced.

And you can tell right away that he's a great educator: "I'll explain first why we use ECC, because in general I don't really understand things when I don't know how they're important" (not the exact words but you get the idea).

Hacking Week posted February 2014

A teacher from my uni (and who was teaching Programming last semester) is organizing a Hacking Week next week. Signs up are still possible there : http://hackingweek.fr/contestant/list/

It should be a Capture The Flag kind of contest. It should be interesting, although I'm going to ski with some friends so I won't be able to be really into it...
