ROT47

What ROT47 does

ROT47 cipher; also length and changed chars.

Practical limit for ROT47: Empty input fails. That is why output can differ from heavy desktop Crypto software. Read the tool-specific note again: ROT47 cipher; also length and changed chars.

How to use ROT47

1. Keep this tab on ROT47 (/crypto/rot47). Pasting into the wrong Crypto tool (for example Caesar Cipher) changes the job.
2. Paste or type the input ROT47 expects. Path hint: crypto · rot47. ROT47 with changed count.
3. Apply the ROT47 action only. Hex Encode is a different transform (Hex encode/decode with bytes.). ROT47 cipher; also length and changed chars.
4. Copy the output of ROT47 if you need it elsewhere. Size/complexity still follows: Empty input fails.
5. If the text job is actually Shift letters by N; optional digit rotation., leave ROT47 and open Caesar Cipher.

When not to use ROT47

Skip ROT47 when a neighbor tool matches better — start with Caesar Cipher or Hex Encode — or when the description already warns the job will fail. In the tool’s own words: ROT47 cipher; also length and changed chars.
