Question 1

How does ROT47 differ from ROT13?

Accepted Answer

ROT13 only rotates letters (A–Z, a–z). ROT47 rotates all 94 printable ASCII characters (! through ~, codes 33–126). This means digits and punctuation are also transformed, making output look more scrambled than ROT13.

Question 2

Is ROT47 secure?

Accepted Answer

No. ROT47 is a fixed, keyless substitution cipher with no secret component — anyone who knows the algorithm (publicly documented) can trivially reverse it. It is used for novelty, obfuscation in puzzles, and hiding spoilers — not for security.

Question 3

How do I encode and decode with ROT47?

Accepted Answer

ROT47 is self-inverse: encoding and decoding use the identical operation. Apply ROT47 to encoded text to decode it; apply it to plain text to encode it. This tool performs both automatically.
