I have a task to decrypt custom made transposition cipher, as I'm not the cryptography expert, I would appreciate any help.
I've been given the table of characters ...
M A N B C
D E F G H
I K L O P
Q R S T U
V W X Y Z
... with images representing:
- swap
- up twice
- left twice
(There's no word about the order of these steps)
The hints are:
MAN
NP = CL
Texts to decode is: ET KO KF
I've tried to fit the steps for getting CL
out of NP
, but with no luck. Also, there's no sign if the characters are "pushed" while making steps, or the character we're moving is being swapped with the next letter (I'm not even sure if we're moving characters or columns or something else). I know it might seem not explained enough, but as I'm not an expert, I wanted to ask you as it might be some known pattern.
