It is a transposition cipher that follows a simple rule for mixing up the characters in the plaintext to form the ciphertext. The Rail fence cipher (also called zigzag cipher) is a transposition cipher. For example, if the message is “GeeksforGeeks” and the number of rails = 3 then cipher is prepared as: As we’ve seen earlier, the number of columns in rail fence cipher remains equal to the length of plain-text message. Experience. How to make RSA that works with bigger p and q value? Can a smartphone light meter app be used for 120 format cameras? Usage. Given a plain-text message and a numeric key, cipher/de-cipher the given text using Rail Fence algorithm. Encrypt and decrypt a file with streams, using an appended initalisation vector java. Kifanga - Online tools (converter, solver, encryption / decryption, encoding / decoding, enciphering / deciphering, translator), with functionality to (convert, solve, decrypt / encrypt, decipher / cipher, decode / encode, translate) with source code written in JavaScript programming language. When you rearrange your text in a "wave" sort of pattern (down, down, up, up, down, down, etc. i success fully able to encrypt text with above patten. When we reach the bottom rail, we traverse upwards moving diagonally, after reaching the top rail, the direction is changed again. The message is written in a zigzag pattern on an imaginary fence, thus its name. So you can know for 99 characters there are 16 full sequences 6*16 = 96 and an additional 4 characters. Let cipher-text = “GsGsekfrek eoe” , and Key = 3, Hence original matrix will be of 3*12 , now marking places with text as ‘*’ we get. Rail fence cipher encryption and decryption is explained here with fully solved example in cryptography. After filling it, we traverse the matrix in zig-zag manner to obtain the original text. Below is an example. Another name for the cipher is zigzag cipher. For this example, we want to send the message “HELLO WORLD”. In the rail fence cipher, the plaintext is written downwards and diagonally on successive "rails" of an imaginary fence, then moving up when we reach the bottom rail. It is a transposition cipher that follows a simple rule for mixing up the characters in the plaintext to form the cipher text. Then we will loop through the string and creat the deciphered string with the corresponding decoded letters. Below is a program to encrypt/decrypt the message using the above algorithm. We will create an object with decoded letter for every alphabet. Example, Let’s say, we take an example of “INCLUDEHELP IS AWESOME”. In Rail Fence Cipher, given a plain-text message and a numeric key then cipher/decipher the given text using the Rail Fence algorithm. Then 1/3 = 'a's, 1/6 = 'c's and 1/2 = "b"s. Here is a simplification of the OP's answer in creating the decipher a, b & c strings. Once we’ve got the matrix we can figure-out the spots where texts should be placed (using the same way of moving diagonally up and down alternatively ). This article is about the Rail Fence Cipher.In this article, we will briefly study the basic Rail Fence cipher and examples aim to capture.We will cover types of messages in Rail Fence cipher. To learn more, see our tips on writing great answers.

In the rail fence cipher, the plain-text is written downwards and diagonally on successive rails of an imaginary fence. This cipher is used to encode a string by placing each character successively in a diagonal along a set of "rails". Railfence. edit https://en.wikipedia.org/wiki/Rail_fence_cipher. Morbi eu sem ultrices, porttitor mi eu, euismod ante. The railfence cipher offers essentially no communication security, and it will be shown that it can be easily broken even by hand. Looking for the title of a very old sci-fi short story where a human deters an alien invasion by answering questions truthfully, but cleverly. Asking for help, clarification, or responding to other answers. Everything will be written in ES6.
