columnar_transposition

This can be used to encrypt or decrypt a Columnar Transposition cipher.
This method is a development of the Scytale cipher that rearranges the encryption matrix used in the
Scytale method by the alphabetical ordering of the encryption key.

Playfair, Four-Square, Scytale, Columnar Transposition and Autokey methods. Further explanation on methods of classical cryptography can be found at Wikipedia; (<https://en.wikipedia.org/wiki/Classical_cipher>).
