Ave's blog, but more random

this one will have more weird shit

This blog post contains parts I cut out from the main blog post I wrote on the topic, and as such is quite messy. Sorry!


I've owned Yubikeys for many years now, and have used them for anything from U2F and have always wondered what was (physically) going on inside them.

I, however, was too lazy to even Google until today. The only resources I could find were teardowns by HexView of Yubikey Neo and Yubikey 5 NFC.

These were quite impressive, and I was honestly surprised at just how little was in them, and how the author mentioned being able to melt the Neo in acetone. I honestly would've expected more, but I suppose that change came with Yubikey 5 series.
