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
