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.
