Security Blanket

Today I turned on the FileVault thingie on my Mac, so every atom of my data is 128-bit encrypted (Pleasingly, there doesn’t seem to be any perceptible slowdown). On top of which, we’re running another 128 bits of encryption on the WiFi around the house, plus the link to the ongoing web host is via ssh which is RSA, uh I forget how many bits in my key. So these humble letters have been through a whole lotta bit-bangin’ along their route from my fingertips to your retina. Getting all this set up takes more work than it really ought to, but it’s getting easier, and once the arrangements are there, it totally doesn’t get in the way. Which is a good thing, because the Internet is a rough neighborhood, and in a rough neighborhood you don’t send your kids walking off to school alone. No more should you send your vulnerable little words out on its mean streets without some cryptographic Block Parents lending a hand.
