Rail Fence Cipher

Description

The Rail Fence Cipher is form of transposition cipher that scrambles the letters. It does this by using a grid of x many rows, and the sender writes the plaintext in the grid in a vertical zig-zag pattern. The key for this cipher is the number of rows (x) that the sender decides to write the message across.

After writing the plaintext cross the grid, the ciphertext can be read off. This is done by reading each row across in descending order.

To decrypt, the letters just have to be arranged in the way they were put and read off in the zig-zag pattern. This makes it easy to decipher. Adding spaces between words into the grid can help, but only to a certain degree.
