ROT13 Encrypt/Decrypt

Online ROT13 encryption/decryption tool supporting ROT13, ROT5, ROT18, ROT47 variants with one-click conversion



Documentation

This tool provides ROT-family substitution transforms, including ROT13, ROT5, ROT18, and ROT47, for quick reversible text obfuscation.

Key Features

  • Switch across four ROT variants
  • Real-time conversion while typing
  • Sample text loading and quick clear
  • Copy output and view character stats

Steps

  1. Select a ROT variant (for example, ROT13).
  2. Enter the source text.
  3. Read the live output on the right.
  4. Copy the result as needed.

Use Cases

  • Lightweight text obfuscation in communities
  • CTF and cryptography beginner exercises
  • Simple reversible transform demos

Notes

  • ROT is not secure encryption.
  • Applying ROT13 twice restores original text.
  • Use modern cryptography for sensitive data.
