Frequently Asked Questions
Is rail fence cipher secure for real secrets?
No. Rail fence is a classical transposition cipher for education and puzzles, not modern security.

Rails are the number of zigzag rows used to route characters before reading row by row. More rails change the transposition pattern.
Are spaces and punctuation removed?
No. The tool preserves every character exactly as typed, including spaces and punctuation.
