So, no way in heck would this work right?  Well, I can’t do the substitution in my head so I worked it out on paper.  K occurs 8 times in K4.  It’s the highest frequency number by 2 (ooohhh) so if there was a shift it would be to align E (PT) with K (CT).

It’s basically a Caesar shift of 6, or is it:



It looka lika no to me.

I was kind of wondering if you could apply the shift and see if any plaintext popped out but besides fox and axe, I got nuthin.

Oh well.
