Transposition Cipher Transposition Cipher is an encryption method which elements are rearranged.
There are many types of transposition cipher such as Rail Fence, Columnar Transposition and Double Transposition.
Rail Fence Rail Fence is the simplest form of Transposition Cipher which the plaintext is written down as a sequence of diagonals and read off as a sequence of rows.
For Example: The plaintext = WELCOME TO CRYPTOGRAPHY
Then the encryption algorithm will be
