What is Rail Fence Cipher Tool

The Rail Fence Cipher Tool encrypts and decrypts text using the rail fence transposition cipher with a configurable number of rails (2-10). Characters are written in a zigzag pattern across the specified number of rows, then read off row by row to produce the ciphertext. Decryption reverses the process by reconstructing the zigzag pattern.
