ROT Cipher
ROT1, ROT5, ROT13, ROT18, ROT47, ROT48 - decode with auto-detect or encode all variants at once.
Examples
Click to auto-detect
Uryyb, Jbeyq! (ROT13)
w6==0 (FC=:5P (ROT47)
Example
"Hello, World!" → all ROT variants
How it works
ROT13 rotates letters by 13 positions (A↔N, B↔O, …). It's its own inverse. ROT5 rotates digits (0–9) by 5. ROT18 = ROT13 + ROT5 (letters and digits). ROT47 rotates all printable ASCII (33–126) by 47. ROT48 is a variant of ROT47.
AUTO DETECT tries all variants and shows results - useful for CTF challenges where you don't know which ROT was used.
