Let us know in the comments if you are having any questions regarding this cryptography cipher Algorithm.Īnd if you found this post helpful, then please help us by sharing this post with your friends. It is a kind of transposition cipher which is also known as zigzag. HELLOWORLD Other cryptography algorithms: Here you will get rail fence cipher program in C and C++ for encryption and decryption.
The following is the Rail Fence Cipher encryption algorithm program in C++. Hence, we will write the program of the Rail Fence Cipher algorithm in C++, although, it’s very similar to C. For encryption we write the message diagonally in zigzag form in a matrix having total rows key and total columns message length.

We will use C++ to write this algorithm due to the standard template library support. The railfence cipher is a very simple, easy to crack cipher. Then reads off to get the ciphertext: HOLELWRDLO For example, if 3 “rails” and the message “HELLOWORLD” is used, the cipherer writes out: H. When the top rail is reached, the message is written downwards again until the whole plaintext is written out. In the rail fence cipher, the plain text is written downwards and diagonally on successive “rails” of an imaginary fence, then moving up when the bottom rail is reached. It derives its name from the way in which it is encoded. The rail fence cipher (also called a zigzag cipher) is a form of transposition cipher.
includeMainly done because it seemed fun, but posted it in case you find it useful. To encrypt plaintext in the Rail Fence Cipher technique, we have to write the plaintext in zig-zag lines across the rails, and then read off each rail. It's probably better to read with a 2D array though. In this post, we will discuss the Rail Fence Cipher. Quick lunch break experiment that doesn't use a two dimensional array. There are exceptions and some cipher systems may use slightly more, or fewer, characters when output versus the number that was input. In common parlance, “cipher” is synonymous with “ code“, as they are both a set of steps that encrypt a message however, the concepts are distinct in cryptography, especially classical cryptography.Ĭodes generally substitute different length strings of character in the output, while ciphers generally substitute the same number of characters as are input. It works by writing your message on alternate lines across the page, and then reading off each line in turn. To encipher or encode is to convert information into cipher or code. The Rail Fence Cipher (also called a zigzag cipher) is a form of transposition cipher. An alternative, less common term is encipherment.

I've gone over my code (although pretty brutal), it seems like it should work so I'm a bit confused.In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption-a series of well-defined steps that can be followed as a procedure. I thought I might have problems because my array lengths might be screwed up if the size is odd, but it is even for 10 so that doesn't seem to be the problem. Now everything generally works fine and will work but just when I thought I had finished everything it started screwing up like this. Anyhow, my problem is: for example when I enter some text, let's say "hello_test", the output is "el_etý~hlots". In the Rail Fence cipher, the message is written downwards on successive rails of an imaginary fence, then moving up when we get to the bottom (like a zig-zag). I'm trying to use the Rail Fence Cipher ( ) which is a transposition cipher. The type of encryption I'm trying to do is extremely simple. This part just takes text from a user though (I'm just posting it because it's simpler and that's where the problem seems to be). In the rail fence cipher, the plain text is written downwards and diagonally on successive rails of an imaginary fence, then moving up when we reach the. The code I will post is the basic encryption part of a program that also takes text documents and encrypts/decrypts them. I'm a beginner at C++ and could use some help to solve a bit of a problem on one of my first projects.
