The rail fence cipher (also called a zigzag cipher) is a classical type of transposition cipher. It derives its name from the manner in which encryption is performed, in analogy to a fence built with horizontal rails.
The Rail Fence cipher is a form of transposition cipher that gets its name from the way in which it is encoded. In the rail fence cipher, the plaintext is written downward and diagonally on successive "rails" of an imaginary fence, then moves up when it gets to the bottom. The message is then read off in rows.
The following Python code can be used to encrypt text with the affine cipher: # Prints a transposition table for an affine cipher. def affine ( a : int , b : int , s : str ): import string D = dict ( enumerate ( string . ascii_lowercase , start = 0 )) E = { v : k for k , v in D . items ()} size = len ( string . ascii_lowercase ) ret = "" print ...
For Python 3, you can use the method str.maketrans() text = "this is an example without capital letters" my_rot13 = str . maketrans ( "abcdefghijklmnopqrstuvwxyz" , "nopqrstuvwxyzabcdefghijklm" ) print ( text . translate ( my_rot13 )) # guvf vf na rknzcyr jvgubhg pncvgny yrggref
