Skip Cipher
The Skip Cipher tool encodes and decodes messages using a transposition technique that reads through the text by jumping a fixed number of characters at a time, producing a scrambled ciphertext that looks random but can be reversed with the correct skip interval. Unlike substitution ciphers such as Caesar or Vigenère that replace individual letters, transposition ciphers like the skip cipher rearrange the positions of letters without altering their identities, which creates a fundamentally different type of cryptographic transformation. The skip cipher shares conceptual roots with the rail-fence cipher and columnar transposition, and it was historically used for its simplicity in field communications where no encryption machinery was available. This tool supports both encryption and decryption with any skip value, and includes brute-force analysis to help you crack intercepted skip cipher messages when the interval is unknown.

How It Works
Define a skip pattern (e.g., skip every 3rd letter). Enter your message and the tool encrypts by skipping letters according to your pattern. Recipients with the same pattern can decrypt.
