Meanwhile the way Bruce Schneier is now using GPG is really only one conceptual leap away from full-blown Tinfoil Hat Linux usage: http://en.wikipedia.org/wiki/Tinfoil_Hat_Linux The difference between "tinfoil hatters" and reasonable people like Bruce Schneier now seems to be how concerned they are with their ability to destroy a harddrive, and TEMPEST.
the way Bruce Schneier is now using GPG Which way is that? Also, from your Tinfoil Hat Linux link, this idea is hilariously awesome: Keystroke monitoring — THL has gpggrid, a wrapper for GPG that lets you use a video game style character entry system instead of typing in your passphrase. Keystroke loggers get a set of grid points, not your passphrase. I wonder if it might be possible to implement that idea into other…
