My only complaint is that the math, which the comic spends a great deal of time discussing, is far less important than the non-obvious potential attacks and pitfalls in implementation (things like ECB).

@nick ... then this isn't really aimed at you.

In earlier stages of learning, simply keeping track of the parts of the process and how they inter-relate is a key learning goal. The parts you are concerned about are indeed important - but only after the student demonstrates some fundamental understanding of how an encryption protocol would operate in the first place.

And here I expected something from XKCD...
Pretty nice, although my head started to hurt towards the end... It is late Friday afternoon after alll. ;)

At least he's holding off on posts about the big arrest and the other "given a fake device" arrests. I have to admire a guy that doesn't jump right on the story of the moment. Thanks.

Damn, A non E mouse beat me to saying that.

I wonder if Mr. Monroe is reading this right now?

Love the way it goes through at more and more detailed levels. I could nitpick some things, of course, but basically it's great.

"A posting AFTER the Friday Squid? What is this world coming to?"

I'm not quite sure what happened either.

@ Bruce,

"I'm not quite sure what happened either."

You don't even have the old "Concord flyer" excuse of "you arrived before you left"...

Stick figures can be expressive. I thought the "little Bobby Tables" xkcd strip was the best introduction to some SQL vulnerabilities I'd seen.
