What this tool is for
Decode ROT13 text, and when the shift is unknown, list all twenty-five rotations at once so you can spot the readable one. That brute force view is the fastest way through a beginner cipher puzzle.
How to use it
- Paste the encoded text.
- Leave the rotation at 13 for standard ROT13.
- Switch to "show all rotations" if the shift is unknown.
