The Password [via].
Seen that scene many times, but it wasn’t until recently that I connected it to something I read years ago.
The Code Breakers” by David Kahn is a classic book on the history of cryptology. In Chapter 2 he described the simple alphabet letter-shift that every schoolboy knows, but then he double-encrypts the shift with a password. Kahn used SWORDFISH as an example.
Using a simple alphabet shift from A to B:
TACKYRACCOONS reads SZBIXQZBBNNMR. Lot of repeated letters, but if you add a key like SWORDFISH to the shift, you get LWQBVGIUJGKJ, and it’s tougher to crack. That’s kind of how the WWII German Enigma machine worked.

I need an aural palate cleanser after that one, so let’s roll with this:
Have a great weekend or two, folks. We’ll keep the porch light on.
