Editing Polybius square (section)

=== Method 3 ===
{| class="wikitable"
|-
! 
! 1 !! 2 !! 3 !! 4 !! 5
|-
! 1
| A || B || C || D || E
|-
! 2
| F || G || H || I/J ||K
|-
! 3
| L || M || N || O || P
|-
! 4
| Q || R || S || T || U
|-
! 5
| V || W || X || Y || Z
|}
An advanced variation, which involves the following: the obtained primary ciphertext (result From Method 2) is encrypted again. In this case, it is written out without being split into pairs.

 3425453443314154

The resulting sequence of digits is cyclically shifted to the left by one step (an odd number of steps [move 3 to the end]):

 4254534433141543

This sequence is again divided into groups of two:

 42 54 53 44 33 14 15 43

And is replaced with the final ciphertext according to the table:
{| class="wikitable"
|+
!Horizontal coordinate
|4
|5
|5
|4
|3
|1
|1
|4
|-
!Vertical coordinate
|2

|4
|3

|5
|3
|-
!Letter
|i
|u
|p
|t
|n
|q
|v
|o
|}

Thus, after encryption, we get "iuptnqvo".
