Over this Memorial Day weekend I've got two major priorities -- one is to add something to the FAQ regarding certificate generation, and the other is to force myself to learn JavaFX [1].
Anyway. I figured to use recent heated -- pardon the pun -- discussions on this list as fodder for a small excursion into JavaFX, and Hotplate is the result. It's a small app that will let you toy around with different numbers and see how they, the Landauer bound, and the Margolus-Levitin limit, affect the time and heat required to brute-force a 128-bit cipher. If you're interested in looking at it, the very first thing you should do is visit http://java.com to get the latest version of the Java virtual machine. Once that's taken care of, you have two choices: 1. Hit http://sixdemonbag.org/Hotplate.jnlp and launch the application through Java Web Start. [2] 2. Download it from http://sixdemonbag.org/Hotplate.jar and double-click to execute. The application is signed in accordance with Java's normal practices. If you get a warning about an invalid signature, don't run it. If you don't trust Java's signing process, you can download a GnuPG-generated clearsig from http://sixdemonbag.org/Hotplate.jar.asc . Full source code is included inside the jarfile, and the entire thing is contributed to the public domain. Enjoy. [1] Not that I'm particularly keen on it, mind you, but the first question hiring managers ask in the DC metro area is, "Are you up with the latest Java technologies?" It pays to learn it just so you can get hired for a job where you'll never use it. [2] Probably the simplest, but not exactly recommended. Java Web Start is a pretty effective malware vector. But if you've got it installed already, well...
