From kafkatrap to honeytrap
The short version is: if you are any kind of open-source leader or senior figure who is male, do not be alone with any female, ever, at a technical conference. Try to avoid even being alone , ever, because there is a chance that a “women in tech” advocacy group is going to try to collect your scalp.

If you've nothing to hide, you've got nothing to fear
Since 1851 Amsterdam had a registry that recorded the following innocent pieces of data about the residents: Name, Date of birth, Address, Marital Status, Parents, Profession, Religion, Previous Addresses and Date of Death if deceased. For many years this system served well and was kept meticulously up to date.

Thomas Ptacek laid out a number of arguments against DNSSEC recently (and in a follow up ). We don't fully agree on everything, but it did prompt me to write why, even if you assume DNSSEC, DANE (the standard for speaking about the intersection of TLS and DNSSEC) is not a foregone conclusion in web browsers.

Auditing GitHub users’ SSH key quality
If you have just/as of late gotten an email about your keys being revoked, this is because of me, and if you have, you should really go through and make sure that no one has done anything terrible to you, since you have opened yourself to people doing very mean things to you for what is most likely a very long time.

What happens when DNS in China is poisoned and pointed at your server
I’ve been using the Internet in one form or another since the mid-80’s. In that time, I’ve seen a lot of strange stuff happening on our global network. On Tuesday, I experienced something extraordinary. It all started with a text message from my partner Ged at 8:30 AM: Mail server down. Please take a look […]

Reassessing Airport Security
News that the Transportation Security Administration missed a whopping 95% of guns and bombs in recent airport security “red team” tests was justifiably shocking. It’s clear that we’re not getting value for the $7 billion we’re paying the TSA annually. But there’s another conclusion, inescapable and disturbing to…

This means that BoringSSL is now powering Chromium (on nearly all platforms), Android M and Google's production services. For the first time, the majority of Google's products are sharing a single TLS stack and making…

Someone recently noticed a Washington Post story on the TSA that originally contained a detailed photograph of all the TSA master keys. It’s now blurred out of the Washington Post story, but the image is still floating around the Internet. The whole thing neatly illustrates one of the main problems with backdoors…

Is Extended Random a Malicious NSA Plot?
Dual_EC was almost certainly an NSA backdoor. Extended Random is the TLS extension that would have made it practical to exploit. Did NSA plant that one too? A look at the evidence.

The Moral Character of Cryptographic Work
Abstract: Cryptography rearranges power: it configures who can do what, from what. This makes cryptography an inherently political tool, and it confers on the field an intrinsically moral dimension. The Snowden revelations motivate a reassessment of the political and moral positioning of cryptography. They lead one to…

The God Login
I graduated with a Computer Science minor from the University of Virginia in 1992. The reason it’s a minor and not a major is because to major in CS at UVa you had to go through the Engineering School, and I was absolutely not cut out for that kind
