What is ROT-47?

ROT-47 (short for “rotate by 47 places”) is a substitution cipher that rotates all visible ASCII characters between ! (ASCII 33) and ~ (ASCII 126). Unlike ROT-13, which only modifies letters, ROT-47 includes letters, numbers, and symbols — making it ideal for more robust data obfuscation.

Common Use Cases
  • Obfuscating short messages or strings in source code or emails
  • Learning basic cryptography concepts in a visual, hands-on way
  • Securing plain-text notes with lightweight encoding
  • Hiding strings in online content temporarily for later retrieval
