Rail Fence Cipher Demo
EDUCATIONAL DEMONSTRATION ONLY — The Rail Fence cipher is a transposition cipher that writes the plaintext in a zigzag pattern across a number of "rails" (rows), then reads off each row to produce the ciphertext. Used since ancient times.

Frequently asked questions
Is the Rail Fence cipher secure?
No. With only N possible rails, it is trivially breakable by trying each one. It has no key space to speak of.
What is a transposition cipher?
A transposition cipher rearranges the order of characters without changing them. The Rail Fence is one of the simplest examples.
