# ROT13 & ROT-N Cipher

> Shift letters by any amount — ROT13, ROT47 and every rotation in between, with a full table.

ROT-N shifts every letter forward by a fixed number of places, wrapping around at the end of the alphabet. ROT13 is the best-known variant because shifting 13 places twice returns the original text. ROT47 does the same across all printable ASCII, so it also transforms digits and punctuation.

## FAQ

### Is ROT13 secure?

Not remotely. There is no key — anyone who recognises the format can reverse it instantly. It exists to hide spoilers and punchlines from casual reading, not to protect anything.
