Fun with Cloudflare Breaking Things

So in moving to Hugo, and moving to a more personally defined blogging experience, I’ve come into a few interesting issues, stuff I might blog about in the future. As part of moving to Hugo, I also moved to using Cloudflare out in front of my site for a few reasons; DDoS protection (Which I never expect to use, but why not), DNS management, and so on.

Why Flipper Zero's U2F Implementation is a Mixed Bag

I’m not going to mince words, this is going to be a rant and it’s going to get messy. There’s going to be diagrams and everything. The Flipper Zero is amazing.

I wrote up a little app to determine whether or not your password has been compromised by testing it against the HIBP ( database of known-compromised passwords. It’s not particularly complex, but it does ensure your password doesn’t actually leave your system by using the k-Anonymity model provided by HIBP in their APIs. My code’s at, take a look!...

Adding U2F to Your Login in Ubuntu!

So I wrote this a few years ago for Ubuntu and it’s pretty useful, so I ported it over from my old blog. I have performed this configuration for Arch Linux as well and frankly I should write a blog about it, because it was a little fiddly. Anyway here’s the old blog. So one thing I really appreciate about Yubikeys is that they force the issue of security. They are a discrete, physical second factor....
