So classically, steganography is the art of hiding something in plain sight.  Gary Phillips had made a point about the text in K4 that made me wonder.  Is it possible that the ciphertext of K4 can be found in the other parts of Kryptos?

Nothing to do but try it.  I printed off my grids of the ciphertext panels, the plaintext of those panels and the vigenere tableau.  The idea was to work from left to right and find the K4 text in order.  Perhaps the orientation of the letters would reveal something or I could cut them out and layer it as a grille  over one of the other sections.

Trying to find the K4 text in the enciphered Copperplate, I made it as far as OBKRUOXOGHULB before I ran out of text.  I chose not to start back at the beginning because I thought that would be stretching the concept a little too much.  To be sure the idea worked, I decided that if it didn’t fit the first time around then it just didn’t work.  I used this standard for the other sections.

Trying to find the K4 text in the plaintext of the Copperplate, I made it as far as OBKRUOXOGHULBSOLIFBBWF.  No luck.

Trying to find the K4 text in the Vigenere tableau was better but only as far as OBKRUOXOGHULBSOLIFBBWFLRVQQPRNGKSSO

Out of curiosity I tried to find the Morse code in K4, a reversal of the method.  I was stumped however and after looking at the letter frequency it becomes easily apparent that with it’s PT frequencies, the Morse code text could never fit into a depressed frequency ciphertext like K4.  For example, there are 14 I’s in the Morse code message and only 4 I’s in the K4 text.

A simple idea to use and reverse engineer but unfortunately, not a successful one.
