Type your text and set the rod diameter (number of rows), and the tool encrypts it the way the ancient Spartan scytale cipher wrapped a strip around a rod.
One of the oldest known ciphers, used by ancient Spartans. A strip of parchment was wound around a rod of a specific thickness; the message was written across the wraps and only lined up again on a rod of the same size.
It represents the rod's circumference — how many characters fit around one turn. The text is written across that many columns row by row, then read down each column to produce the ciphertext.
Yes. The scytale is a pure transposition (it only rearranges characters), and this tool tracks the exact grid, so decoding with the same number of columns returns your original text including spaces and punctuation.
