Rail Fence Cipher

Calculates a simple substitution cipher by rearranging letters into a specific zigzag pattern, known as the Rail Fence Cipher. The tool encrypts plain text by simulating writing across multiple "rails," which determines the number of rows used for the transposition. It then reads the characters in sequence to produce a scrambled ciphertext that is visually displayed alongside the original input and the encryption parameters selected by the user. Individuals studying cryptography, learning about basic ciphers, or engaging in historical puzzle-solving find this utility useful. Users can experiment with different key values—the number of rails—to see how varying transposition methods alter the resulting encrypted message. It provides a clear visualization of the cipher process and includes functionality to decrypt messages, allowing users to reverse the scrambling process accurately.
