Encrypt and decrypt with the ancient Spartan scytale rod transposition cipher. Round-trip guaranteed. Scytale Cipher is a free online tool from the ToolsRift Text Encoding Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
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.
