WebThe rail fence cipher is a very old encryption scheme, pre-dating the Middle Ages. It was used as a field cipher by both sides in the US Civil War. The number of rails used to break up the message serves as the cryptographic key. The rail fence cipher is not very strong. WebIn cryptography, the clock was a method devised by Polish mathematician-cryptologist Jerzy Różycki, at the Polish General Staff's Cipher Bureau, to facilitate decrypting German …

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. See more In the rail fence cipher, the plaintext is written downwards diagonally on successive "rails" of an imaginary fence, then moving up when the bottom rail is reached, down again when the top rail is reached, and so on … See more Let $${\displaystyle N}$$ be the number of rails used during encryption. Observe that as the plaintext is written, the sequence of each letter's vertical position on the rails varies up and down … See more The term zigzag cipher may refer to the rail fence cipher as described above. However, it may also refer to a different type of cipher described by Fletcher Pratt in Secret and Urgent. It is "written by ruling a sheet of paper in vertical columns, with a letter at the head of … See more The cipher's key is $${\displaystyle N}$$, the number of rails.
