I can’t imagine why, but I have something of a foil-hat reputation among my friends. They point to my lack of a cell phone (for various reasons), my avoidance of credit cards, my tendency to give fake addresses and phone numbers at Fry’s, and my incessant rants about Social Security numbers.
Given all that, I don’t know why it took me so long, but I finally generated a PGP keypair for myself. Whee! I also uploaded it to MIT’s keyserver and posted a link on my contact page. Not that I expect you to use it to email me your bank account number, or your mother’s maiden name…but if you really want to, now you can!
