-The Myszkowski Transposition Cipher is a variant of Columnar Transposition.
-It deals with recurring letters in the keyword.
EXAMPLE:
Plaintext: Loving right is loving a person with self preservation
Keyword: marem
Write the plaintext in a grid. The number of letters of the keyword should be the same as the number of columns in the grid. In my example, the keyword I used has 5 letters. So it means that the number of columns of my grid is also 5. Next, number each letter of the keyword with its alphabetical order. Put the same number for the repeated letters of the keyword.
It becomes like this;
(Note: If the columns isn't balanced, add letter X)
M A R E M
3 1 4 2 3
-------------------
l o v i n
g r i g h
t i s l o
v i n g a
p e r s o
n w i t h
s e l f p
r e s e r
v a t i o
n x x x x
-Now, let's get the ciphertext. Let's start to the column headed by 1. Since it doesn't have a duplicate, we'll just directly read it off in columns. Here it is: ORIIEWEEAX
-Column number 2 just like the column 1, we'll just directly read it off in columns since it doesn't have a duplicate. Here it is: IGLGSTFEIX
-Next is column number 3. As you can see, there are two column #3. What we are going to do is to read the letters from each column starting from left to right.
-Now, let's apply it. Let's start with the column #3 in the left. As you can see, the first letter is the letter L. Next, let's look at the column #3 in the right. The first letter is the letter N. So, it will become LN. Back to the left, the second letter is the letter G. Next, back to the right, second letter is the letter H. It will become GH. Continuing the steps, we will get: LNGHTOVAPONHSPRRVONX
-And for the 4th column, just like the first two columns, read it off in columns directly. Here it is: VISNRILSTX
The final ciphertext is ORIIE WEEAX IGLGS TFEIX LNGHT OVAPO NHSPR RVONX VISNR ILSTX
