WN: How many (cryptographic) techniques did you use (in Kryptos)?
Sanborn: I would think five or six.
(WIRED Interview, 01/20/05)

So let’s see…

Morse Code (#1)

K1 (#2)

K2 (#3?, it’s not much different from K1…)

K3 (#4)

K4… worst case we’ve got like 2 or 3 cipher methods used here.

Did you hear that all you multi-steppers out there?  2 or 3…

Not 312.  Or 657.

If it doesn’t work after 3 cipher systems are in play, then IT’S NOT GOING TO WORK AT ALL.

I’m doing what I can to pound a few more nails in that particular coffin.
