Tool to decrypt/encrypt using a scytale. Scytale is a very basique transposition cipher used in ancient Greece and by spartans. A band is wrapped around a rod, a message is written, and when the band is unrolled a ciphertext appears.

**Scytale** Encryption uses a cylinder and a band characterized by its number of turns `L` of the band around the cylinder.

__Example:__ Code `DCODE` with a band `L=3`.

The message is written along the cylinder, one letter per band, and when the end is reached, go to a new line.

If needed, complete the last line with another character, e.g. `X` or `_`.

__Example:__

DCO |

DE_ |

The ciphered message is the band unrolled, (i.e the message read by column).

__Example:__ The cipher text is `DDCEO_`

**Scytale** Decryption requires to know the number `N` of letters by turn of the band (the size of the cylinder), or `L` the number of turns around the cylinder.

__Example:__ The ciphertext is `DDCEO_` (6-character long) and the band is `L=3`, then `N=2` (because 6/3=2).

Write the message on the band and wraps the band around the cylinder (of correct size) and the plain text should appear.

__Example:__

To make a real **scytale**, the parchment ribbon and rolled top-down around a wooden cylinder (a solid stem or a regular wood branch).

The Plutarch's staff is the other name given to the **Scytale**, because the philosopher Plutarch is one of the first to have described this encryption process.

The coincidence index is equal to the one of the original text (as it is a transposition cipher).

The plutarch's staff is the name given to an album of Blake and Mortimer.

One can crack **Scytale** by testing all possible size of the rectangle.

**Scytale** is a practical application of the Caesar Cipher.

8 to 6 centuries BC even if Plutarch describes it only 1 century BC
