      I lost another password. This time OpenBSD FDE. So obviously here's a head-first dive into the OpenBSD core source.https://blog.filippo.io/so-i-lost-my-openbsd-fde-password/ …

      Brute force tools are those rare pieces of software in which you are incredibly relieved every time you find a bug. Hope 🔄 disappointment.

      I FOUND IT! 🎉 I was reusing a buffer, corrupting all attempts after the first. Fixed that. Apparently... I mispelled an Italian word 😥

          Apparently buffers are still landmines, even in memory safe languages. :)

          I once wandered into an Umbrian bar. Bought a drink, held out some coins and said, "mi diaspace, non parlo Italiano"

          an Italian drunk to my right sighs and responds, "but you're speaking Italian right now."

          I try to learn “don’t worry, I don’t speak X” in as many languages as possible to spook foreign ppl who speak amongst them

          Since it's pbkdf2, presumably it could be sped up using something like h1kari's FPGA WPA2 & filevault cracking PoCs?

          So how long was it running over what sort of keyspace to give us an estimate of the time to brute force the FDE?
